QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
625 PM EDT SUN AUG 02 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 06/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.


DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD

FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 06/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.


DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
625 PM EDT SUN AUG 02 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 06/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.


DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
625 PM EDT SUN AUG 02 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 06/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.


DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
625 PM EDT SUN AUG 02 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 06/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.


DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
625 PM EDT SUN AUG 02 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 06/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.


DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD

PRELIM DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 06/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR

DAY 1...


...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.

DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.

DAYS 2/3...

...NORTHERN TO CENTRAL ROCKIES/NORTHERN PLAINS...

THE MODELS CONTINUE TO SHOW THE LOW-MID LEVEL RIDGE BREAKING DOWN
WITH A 700 MB WAVE AND POSSIBLE EMBEDDED LOW OR LOWS MOVING ACROSS
THE NORTHERN ROCKIES DAY 2 AND ACROSS THE NORTHERN PLAINS TO
POSSIBLY THE UPPER MS VALLEY DAY 3.  AHEAD OF THE WAVE PRE FRONTAL
CONVERGENCE AND UPPER DIVERGENCE MAXIMA HELP TO INDUCE ASCENT.
MODEL DIFFERENCES STEM FROM TIMING AND AMPLITUDE DIFFERENCES IN
THE 700 MB WAVE...WITH A CONTINUED LACK OF CLUSTERING OF
SOLUTIONS.  THE 12Z GFS WAS ON THE FASTER SIDE OF THE SUITE OF
SOLUTIONS WITH THE NAM AND ECMWF SLOWER.  MORE WEIGHTING WAS GIVEN
TO THE LATTER HALF BUT STILL A CONSENSUS APPROACH WAS USED...WITH
LESS WEIGHT ON THE HEAVIER NAM IN WESTERN WY DAY 2.  USED A BLEND
OF THE 00Z-12Z ECMWF/GFS/09Z SREF MEAN DAY 2....FOLLOWED BY A
BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z GEFS MEAN DAY 3 AS THE GFS
WAS HEAVIER FURTHER EAST INTO SOUTHWEST MN...COUNTERED BY THE GEFS
MEAN BETTER MATCHING THE UKMET AND ECMWF.

ON DAY 3....WHILE THE LEAD WAVE CROSSES THE DAKOTAS A SECOND WAVE
DEVELOPS IN THE PACIFIC NORTHWEST...WITH SCATTERED SHOWERS
DEVELOPING ON THE NORTHERN ROCKIES AGAIN AS A POOL OF MOISTURE
NEAR 700 MB AND VERTICAL VELOCITY MAXIMA DEVELOP. HERE THE MODELS
ARE IN BETTER AGREEMENT SO A STRAIGHT CONSENSUS WAS USED IN
ID/MT/WY.

...CENTRAL TO SOUTHERN PLAINS/MIDWEST/MS VALLEY/OH VALLEY...

ON DAY 2...A BAND OF SHOWER/STORMS DEVELOPS FROM THE SOUTHEAST
CORNER OF SD ACROSS NORTHEAST NE TO SOUTHWEST IA IN AN AREA OF LOW
LEVEL FRONTOGENESIS AND 850-700 MB THETA-E ADVECTION AND
CONVERGENCE.  THIS AREA SHEAR OUT DOWNSTREAM INTO THE MID MS
VALLEY DAY 3.

A PAIR OF 850-700 MB SHORTWAVES MOVING OUT OF THE ROCKIES HELP
INCREASE MOISTURE AND LIFT ACROSS
THE CENTRAL TO ADJACENT SOUTHERN PLAINS DAY 2.  LOW-MID LEVEL
THETA-E ADVECTION AND CONVERGENCE SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES OVER WESTERN KS AND NEAR THE WESTERN OK/TX BORDER,
MOVING EAST NORTHEAST ACROSS KS AND OK INTO MO. CONTINUED SLIGHT
RISK OF EXCESSIVE RAINFALL.  EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  MANUAL PROGS BLENDED THE
QPF FROM THE 00-12Z ECMWF/12Z UKMET/1Z NAM WITH LESS WEIGHT ON THE
GFS...WHICH MOVES THE 700 MB LOW FASTER AND BRINGS QPF FURTHER
NORTHEAST INTO IL/IN.  THIS IS OFFSET BY THE GEFS MEAN...WITH THE
GEFS MUCH FURTHER SOUTH IN IL/IN LIKE THE OTHER MODELS/09Z SREF
MEAN.
THE GFS APPEARS TO BE SUFFERING FROM CONVECTIVE/GRID SCALE
FEEDBACK.

...SOUTHEAST/FLORIDA...

A LOW PRESSURE AREA MOVING ONSHORE FROM THE GULF OF MEXICO ACROSS
NORTHERN FL THEN MOVES NORTHEAST OFF THE SOUTHEAST COAST.  LOW
LEVEL CONVERGENCE NEAR THE LOW AND ASSOCIATED FRONTAL BNDRY LEADS
TO COASTAL SHOWERS FROM GA ACROSS THE CAROLINAS.  A TIGHT RAINFALL
GRADIENT IS ANTICIPATED ALONG THE COASTS OF SC AND NC, SO ANY
WESTWARD SHIFT OF THE LOW TRACK COULD BRING AMOUNTS UP
SUBSTANTIALLY.

WITH THE LOW DEPARTING FL...HIGH PRESSURE BUILDS IN ACROSS THE
STATE.  THIS LEADS TO A RETURN OF A MORE TYPICAL AUGUST DIURNAL
PATTERN...WITH SHOWERS AND STORMS CONCENTRATED IN THE PEAK
AFTERNOON WARMTH.
LIGHT FLOW IN THE PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
DRIFTING INLAND EACH AFTERNOON. USED A COMPROMISE OF THE 00Z-12Z
GFS/ECMWF FOR THE QPF IN THIS REGION.

...NORTHEAST...

SHOWERS AND THUNDERSTORMS WITH MODERATE TO BRIEFLY HEAVY RAINFALL
ARE EXPECTED TO IMPACT NORTHERN NEW ENGLAND AND EASTERN NY MONDAY
EVENING. THE 15Z SREF MEAN SHOWS CAPES 1000-1500 J/KG WHILE THE
GFS ADVERTISES 850 HPA FLOW OF 30-40 KTS STREAMING ACROSS THE
REGION. THE PROGRESSION OF THE COLD FRONT ALLOWS SHOWERS AND
STORMS TO STEADILY MOVE EAST...MOVING OFF THE COAST TUE MORNING.
AFTER THIS OCCURS...CYCLONIC FLOW ACROSS THE GREAT LAKES INTO THE
NY ADIRONDACKS AND VT GREEN MOUNTAIN BRING SHOWERS TUE AFTERNOON
AND NIGHT AND POCKETS AND LOW LEVEL CONVERGENCE AND LIFT OCCUR
WHERE 700 MB RELATIVE HUMIDITY REMAINS ABOVE 70 PERCENT.  MANUAL
PROGS USED A GFS/UKMET/ECMWF/NAM MODEL CONSENSUS...ALONG WITH
CONTINUITY.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION

303 PM EDT SUN AUG 02 2015


PRELIM DAY 1 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 04/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
303 PM EDT SUN AUG 02 2015


PRELIM DAY 1 QPF DISCUSSION
VALID AUG 03/0000 UTC THRU AUG 04/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


...FLORIDA AND THE SOUTHERN ATLANTIC COAST...

AFTERNOON THUNDERSTORMS IN FLORIDA WILL HAVE A TENDENCY TO
MAXIMIZE ALONG THE EAST COAST...BUT ONLY BRIEFLY...AS
SOUTHWESTERLY FLOW ALOFT PROMOTES REASONABLY QUICK PROGRESSION
OFFSHORE. A LONGER LIVED FOCUSING MECHANISM WILL CONTINUE TO FAVOR
RAIN OVER THE WEST AND NORTHWEST COAST...NEAR AND NORTH OF TAMPA
BAY. THE GREATEST CONCERN FOR HEAVY RAIN IS JUST TO THE SOUTH OF A
SURFACE LOW PRESSURE CENTER...WHERE LOW LEVEL CONVERGENCE AND LOW
LEVEL INFLOW OFF THE GULF WILL BE MAXIMIZED FOR QUITE SOME
TIME...ESPECIALLY TONIGHT...AS THE LOW MOVES VERY SLOWLY EASTWARD.
THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH OF TAMPA
BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION HERE MAY BE
SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT RAINFALL
PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING. THE HIGH
RESOLUTION MODELS HAD GENERALLY OVER-FORECAST THIS EVENT UP TO
THIS POINT IN TIME...WHICH MAY BE RELATED TO RESOLUTION...AS THE
WEAKLY UNSTABLE ENVIRONMENT LENDS ITSELF TO SMALLER CONVECTIVE
ELEMENTS THAT DO NOT TRAIN ACROSS THE SAME POINTS SO EASILY.

CONDITIONS SUPPORTING HEAVY RAIN SHOULD INCREASE
TONIGHT...HOWEVER...WITH THE LOW LEVEL WIND FIELDS STRENGTHENING
ONSHORE...OWING TO A SLIGHT EASTWARD SLIDE OF THE SURFACE
LOW...AND IN RESPONSE TO NORTHERN STREAM JET FORCING THAT WILL
SUPPORT A MORE BROAD SCALE AMPLIFICATION OF THE EXISTING UPPER
LEVEL TROUGH.

THE SAME COULD BE SAID FOR THE COAST OF SOUTH CAROLINA...AND
POTENTIALLY PARTS OF ADJACENT GA/NC...WHERE DEEP MOISTURE HAD
REMAINED IN PLACE. DESPITE SOMEWHAT MARGINAL LAPSE RATES AND
INSTABILITY...STRONG HEATING HAD YIELDED LOCALLY STRONG AND SLOW
MOVING CELLS WITH HEAVY RAIN AS OF MIDDAY. AFTER AN EVENING
LULL...ACTIVITY SHOULD INCREASE AGAIN TOWARD MORNING...WITH THE
BROAD SCALE PATTERN AMPLIFYING TO BRING STRONGER SOUTHERLY FLOW
ONSHORE...AHEAD OF THE APPROACHING SURFACE LOW OVER FLORIDA. SOME
OF THE 00Z HI-RES MODELS INDICATED HEAVY RAIN FOR THE SC COAST
MONDAY MORNING...AND NOW MORE OF THE 12Z GUIDANCE HAS TRENDED IN
THIS DIRECTION.

WPC BLENDED THE PREVIOUS FORECAST OVER THE SOUTHEAST U.S. TOWARD
THE 12Z HI-RES MODELS.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE DEEPEST FORCING WILL TRACK TOWARD NEW
ENGLAND...WHILE THE GREATER INSTABILITY WILL REMAIN CENTERED BACK
TOWARD THE MIDWEST STATES. THE BEST COMBINATION IS IN
BETWEEN...WITH NUMEROUS MODELS PLACING A 24-HR QPF MAXIMUM ACROSS
MICHIGAN...WHERE MIDDAY CONVECTION HAD ALREADY ESTABLISHED
OUTFLOWS TO INTERCEPT INCREASING SOUTHWESTERLY FLOW LEVEL FLOW
FROM AN UNSTABLE SOURCE REGION.

MODELS HAD TRENDED TOWARD FAIRLY GOOD AGREEMENT...AND THE WPC
FORECAST WAS BASED LARGELY ON THE DETAILS OF THE 12Z NAM
CONEST...12Z GFS...AND THE 00Z SSEO MEAN AVAILABLE OUT THROUGH
MONDAY MORNING.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE YIELD
RELATIVELY GENEROUS COVERAGE OF CONVECTION TODAY THROUGH
MONDAY...ESPECIALLY OVER EASTERN UT AND WESTERN CO. PRECIPITABLE
WATER VALUES HERE WILL BE SLIGHTLY ABOVE CLIMATOLOGICAL
VALUES...AND WILL SUPPORT A RISK OF FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS ISOLATED RAINFALL TOTALS ABOVE
1.5 INCHES WILL BE POSSIBLE. LOCATIONS RECEIVING THE MOST RAINFALL
WILL LIKELY BE DETERMINED BY VERY SMALL SCALE CELL MERGERS AND
ACCIDENTAL RATHER THAN ORGANIZED TRAINING...GIVEN A RELATIVE LACK
OF STRONG INFLOW NEAR CLOUD BASE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE SUNDAY
EVENING...WITH THIS COMBINATION THEN MIGRATING TOWARD NORTHERN UT
/ NORTHWEST CO / SOUTHWEST WY ON MONDAY.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NORTHERN
NV/CA AND SOUTHERN OR...THEN MIGRATING DEEPER INTO CENTRAL AND
NORTHEAST OR ON MONDAY. A PLUME OF RICH MID LEVEL MOISTURE...BUT
MARGINAL INSTABILITY FOR SURFACE BASED PARCELS...SHOULD KEEP THE
MORE SUBSTANTIAL PRECIPITATION AMOUNTS TIED CLOSELY TO THE HIGHER
TERRAIN. SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE
SUGGESTS THAT ISOLATED ONE INCH AMOUNTS ARE POSSIBLE...ALTHOUGH
AMOUNTS LESS THAN 0.50 INCHES WILL BE MORE COMMON.

THE EASTERN EXTENT OF THE MONSOONAL MOISTURE SITS ATOP THE
SOUTHERN HIGH PLAINS...WHERE MOISTURE AND INSTABILITY HAVE
GRADUALLY FADED THE PAST FEW DAYS UNDER THE INFLUENCE OF REPEATED
LOCAL SCALE CONVECTION AND SOME DRYING AROUND A SURFACE HIGH
LOCATED IN THE MID MISSISSIPPI VALLEY. THROUGH MONDAY ADDITIONAL
SMALL SCALE CONVECTIVE CLUSTERS AND INDIVIDUAL THUNDERSTORM
DEVELOPMENT WILL BE MAINLY CONFINED TO EITHER SIDE OF AN AXIS FROM
SE CO TO W TX AROUND LUBBOCK. IT IS ALONG THAT AXIS THAT THERE IS
A FAIR MODEL CONSENSUS FOR HYDROLOGICALLY SIGNIFICANT 24-HOUR
AREAL AVERAGE TOTALS EXCEEDING A QUARTER INCH.

THROUGHOUT THE WESTERN U.S...WPC QPF BLENDED THE PREVIOUS FORECAST
TOWARD THE 12Z WRF-ARW AND THE 12Z GFS.

...FLORIDA...

DEEP TROPICAL MOISTURE RESIDING BENEATH A BROAD UPPER LEVEL TROUGH
WILL FEED SURGES OF CONVECTION THAT TRACK WEST TO EAST ACROSS THE
CENTRAL AND NORTHERN FLORIDA PENINSULA. THE GREATEST CONCERN IS
JUST TO THE SOUTH OF A SURFACE LOW PRESSURE CENTER...WHERE LOW
LEVEL CONVERGENCE AND LOW LEVEL INFLOW OFF THE GULF WILL BE
MAXIMIZED FOR QUITE SOME TIME...AS THE LOW MOVES VERY SLOWLY
EASTWARD. THIS INCLUDES THE STRETCH OF COAST FROM NEAR AND NORTH
OF TAMPA BAY UP THROUGH CEDAR KEY AND STEINHATCHEE. CONVECTION
HERE MAY BE SHALLOW AT TIMES...BUT STILL HIGHLY EFFICIENT AT
RAINFALL PRODUCTION GIVEN WARM RAIN PROCESSES AND TRAINING.
EFFICIENCY MAY BE ENHANCED DURING THE OVERNIGHT HOURS WHEN THE
BOUNDARY LAYER DECOUPLES AND STRONGER LOW LEVEL SOUTHWESTERLY
WINDS WILL CONTINUE TO PROGRESS ONSHORE. A BASIN AVERAGE OF 3 TO 4
INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY AND KBKV.

IT SHOULD BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION
GUIDANCE...SUCH AS THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE
POTENTIAL FOR AN ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE
TRAINING OCCURS. THERE IS SOME MODEL SPREAD ON WHERE THE QPF
MAXIMUM OCCURS.

ELSEWHERE...THE VERY HIGH MOISTURE CONTENT ON THE LARGER SCALE
SHOULD SUPPORT LOCALLY INTENSE RAIN RATES THROUGHOUT FLORIDA...BUT
THERE ARE FACTORS COMBATING A MORE ORGANIZED LARGE SCALE EXCESSIVE
RAIN THREAT. LAPSE RATES HAD GROWN LESS STEEP WITH TIME AFTER A
FEW DAYS OF ACTIVE CONVECTION...AND LAPSE RATES WERE NOT BEING
REPLENISHED GIVEN RELATIVELY LITTLE LIFT ASSOCIATED WITH THE WEAK
TROUGH / SHEAR ZONE. DAYTIME CONVECTION WILL TEND TO PROPAGATE
WITH DECENT FORWARD MOTION ALONG OUTFLOWS...CUTTING DOWN ON
RESIDENCE TIME OVER A GIVEN POINT.


...COASTAL SOUTH CAROLINA AND GEORGIA...

A NARROW ZONE NEAR THE COAST MAY RECEIVE TWO ROUNDS OF HEAVY RAIN
THROUGH MONDAY MORNING. THUNDERSTORMS DEVELOPING DURING AFTERNOON
HEATING WILL MOVE VERY SLOWLY. LATER IN THE NIGHT SOUTHERLY LOW
LEVEL FLOW WILL INCREASE UP TO AND POSSIBLY ONTO THE COAST OF
SOUTH CAROLINA...AHEAD OF AN APPROACHING WEAK BUT WELL DEFINED LOW
LEVEL CYCLONE MOVING THROUGH NORTHERN FLORIDA. MODELS SUCH AS THE
00Z WRF-ARW AND WRF-NMM PLACE HEAVY RAINFALL ONSHORE IN SC LATE
TONIGHT...WHILE OTHERS REMAIN JUST OFFSHORE. QUESTIONS ABOUT
PLACEMENT AND RECENT TRENDS TOWARD POOR LAPSE RATES IN THE LOWER
TO MIDDLE LEVELS CAUSED WPC TO STOP SHORT OF ADDING A SLIGHT RISK
FOR THIS AREA...BUT RICH MOISTURE WILL SUPPORT ISOLATED VERY HEAVY
RAIN RATES WHEREVER CONVECTION DOES FORM.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHTLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE AN AREA
OF SCATTERED TO BROKEN CONVECTION...WHICH COULD PRODUCE HEAVY TO
LOCALLY EXCESSIVE RAINFALL.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS)...NORTHERN NM AND SOUTHEAST UT. PRECIPITABLE WATER
VALUES HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS
ABOVE THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF
THE HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS
ARE POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND
BASED ON WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS
POSSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND NORTHERN NM SEEM TO BE IN THE
AREAS WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. A SLIGHT RISK AREA WAS ISSUED FOR THIS AREA.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. PRECIPITABLE WATER VALUES FROM
NORTHERN CA/SOUTHWEST OR THROUGH MUCH OF NV SHOULD TOP OUT BETWEEN
TWO AND THREE STANDARD DEVIATIONS ABOVE THE MEAN....AND MARGINAL
INSTABILITY SHOULD INITIATE CONVECTION MAINLY OVER THE TERRAIN.
SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE (LIKE THE 00Z
NAM CONEST) SUGGESTS THAT LOCAL 1.00+ INCH AMOUNTS ARE POSSIBLE
ACROSS THE TERRAIN OF CENTRAL NV. WITH A SHORT WAVE CROSSING THE
REGION FOR SYNOPTIC SCALE ASCENT...LOCAL QPF AMOUNTS OF THIS
MAGNITUDE ARE PLAUSIBLE. GIVEN THE HIGH MOISTURE CONTENT OF THE
AIR...A SEE TEXT WAS PLACED OVER NV.

ELSEWHERE...THE VERY HIGH MOISTURE CONTENT ON THE LARGER SCALE
SHOULD SUPPORT LOCALLY INTENSE RAIN RATES THROUGHOUT FLORIDA...BUT
THERE ARE FACTORS COMBATING A MORE ORGANIZED LARGE SCALE EXCESSIVE
RAIN THREAT. LAPSE RATES HAD GROWN LESS STEEP WITH TIME AFTER A
FEW DAYS OF ACTIVE CONVECTION...AND LAPSE RATES WERE NOT BEING
REPLENISHED GIVEN RELATIVELY LITTLE LIFT ASSOCIATED WITH THE WEAK
TROUGH / SHEAR ZONE. DAYTIME CONVECTION WILL TEND TO PROPAGATE

RESIDENCE TIME OVER A GIVEN POINT.


...COASTAL SOUTH CAROLINA AND GEORGIA...

A NARROW ZONE NEAR THE COAST MAY RECEIVE TWO ROUNDS OF HEAVY RAIN
THROUGH MONDAY MORNING. THUNDERSTORMS DEVELOPING DURING AFTERNOON
HEATING WILL MOVE VERY SLOWLY. LATER IN THE NIGHT SOUTHERLY LOW
LEVEL FLOW WILL INCREASE UP TO AND POSSIBLY ONTO THE COAST OF
SOUTH CAROLINA...AHEAD OF AN APPROACHING WEAK BUT WELL DEFINED LOW
LEVEL CYCLONE MOVING THROUGH NORTHERN FLORIDA. MODELS SUCH AS THE
00Z WRF-ARW AND WRF-NMM PLACE HEAVY RAINFALL ONSHORE IN SC LATE
TONIGHT...WHILE OTHERS REMAIN JUST OFFSHORE. QUESTIONS ABOUT
PLACEMENT AND RECENT TRENDS TOWARD POOR LAPSE RATES IN THE LOWER
TO MIDDLE LEVELS CAUSED WPC TO STOP SHORT OF ADDING A SLIGHT RISK
FOR THIS AREA...BUT RICH MOISTURE WILL SUPPORT ISOLATED VERY HEAVY
RAIN RATES WHEREVER CONVECTION DOES FORM.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE IN THE SOUTHWEST STATES REMAINS CONNECTED TO A
PLUME EMANATING FROM THE EASTERN PACIFIC UP THROUGH SONORA.
PORTIONS OF THE MOISTURE ARE THEN DIVERTED INTO THE GREAT BASIN
AND SOUTHERN PLAINS...FOLLOWING A MID LEVEL SHEAR AXIS LAID OUT
ROUGHTLY WNW TO ESE. THE HIGH MOISTURE CONTENT AIR...COMBINED WITH
MARGINAL INSTABILITY AND LIFT FROM A SHORT WAVE CROSSING THE
SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO PRODUCE AN AREA
OF SCATTERED TO BROKEN CONVECTION...WHICH COULD PRODUCE HEAVY TO
LOCALLY EXCESSIVE RAINFALL.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS)...NORTHERN NM AND SOUTHEAST UT. PRECIPITABLE WATER
VALUES HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS
ABOVE THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF
THE HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS
ARE POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND
BASED ON WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS
POSSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND NORTHERN NM SEEM TO BE IN THE
AREAS WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. A SLIGHT RISK AREA WAS ISSUED FOR THIS AREA.

FARTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. PRECIPITABLE WATER VALUES FROM
NORTHERN CA/SOUTHWEST OR THROUGH MUCH OF NV SHOULD TOP OUT BETWEEN
TWO AND THREE STANDARD DEVIATIONS ABOVE THE MEAN....AND MARGINAL
INSTABILITY SHOULD INITIATE CONVECTION MAINLY OVER THE TERRAIN.
SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE (LIKE THE 00Z
NAM CONEST) SUGGESTS THAT LOCAL 1.00+ INCH AMOUNTS ARE POSSIBLE
ACROSS THE TERRAIN OF CENTRAL NV. WITH A SHORT WAVE CROSSING THE
REGION FOR SYNOPTIC SCALE ASCENT...LOCAL QPF AMOUNTS OF THIS
MAGNITUDE ARE PLAUSIBLE. GIVEN THE HIGH MOISTURE CONTENT OF THE
AIR...A SEE TEXT WAS PLACED OVER NV.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD

FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/1200 UTC THRU AUG 05/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR



DAY 1...


...SOUTHEAST/FL...

DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL...GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS/ECMWF
CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A BIT
FURTHER NORTH...THE 00Z ECMWF A BIT FURTHER SOUTH). EACH SOLUTION
HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW AVERAGE
CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF. FOR
NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS IS
WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST MOVES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/ECMWF...THE HIGH RESOLUTION
GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM QPF. GIVEN
THE SPREAD IN PLACE... A SLIGHT RISK AREA WAS PLACED OVER MUCH OF
THE WESTERN PORTION OF THE PENINSULA FROM KTPA NORTHWEST INTO THE
BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN IA/NORTHERN AND CENTRAL IL INTO TO THE
MID AFTERNOON. WHILE THERE WILL BE ENOUGH MOISTURE AND LOW LEVEL
MOISTURE FLUX FOR LOCALLY HEAVY RAINFALL... THE CLUSTER SHOULD BE
MOVING WITH THE MID LEVEL FLOW...SO THE POTENTIAL FOR ORGANIZED
FLASH FLOODING DURING THIS TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/ECMWF...AND WAS AUGMENTED BY THE 00Z WRF ARW TO
BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN... INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. A SLIGHT RISK AREA WAS ISSUED TO COVER THE THREAT.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. PRECIPITABLE WATER VALUES FROM
NORTHERN
CA/SOUTHWEST OR THROUGH MUCH OF NV SHOULD TOP OUT BETWEEN TWO AND
THREE STANDARD DEVIATIONS ABOVE THE MEAN....AND MARGINAL
INSTABILITY SHOULD INITIATE CONVECTION MAINLY OVER THE TERRAIN.
SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE (LIKE THE 00Z
NAM CONEST) SUGGESTS THAT LOCAL 1.00+ INCH AMOUNTS ARE POSSIBLE
ACROSS THE TERRAIN OF CENTRAL NV. WITH A SHORT WAVE CROSSING THE
REGION FOR SYNOPTIC SCALE ASCENT...LOCAL QPF AMOUNTS OF THIS
MAGNITUDE ARE PLAUSIBLE. GIVEN THE HIGH MOISTURE CONTENT OF THE
AIR...A SEE TEXT WAS PLACED OVER NV.



DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT AT ALL.  THE 21Z SREF MEAN SHOWS
CAPE VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH
THE INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE
ROUNDS FOR PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A
BETTER OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH
FLOOD GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT
RAINFALL.  PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE
AREAS TO DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A
MODERATE RISK FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF
HAD A BETTER HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND
MIDWEST (EVEN WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS),
WITH THE 00Z UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z
GFS/00Z NAM/00Z UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE
WESTERN OK/TX BORDER, WHICH THE PAST COUPLE DAYS OF ECMWF RUNS
HAVE BEEN TRENDING TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
530 AM EDT SUN AUG 02 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/1200 UTC THRU AUG 05/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR



DAY 1...


...SOUTHEAST/FL...

DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL...GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS/ECMWF
CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A BIT
FURTHER NORTH...THE 00Z ECMWF A BIT FURTHER SOUTH). EACH SOLUTION
HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW AVERAGE
CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF. FOR
NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS IS
WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST MOVES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/ECMWF...THE HIGH RESOLUTION
GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM QPF. GIVEN
THE SPREAD IN PLACE... A SLIGHT RISK AREA WAS PLACED OVER MUCH OF
THE WESTERN PORTION OF THE PENINSULA FROM KTPA NORTHWEST INTO THE
BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN IA/NORTHERN AND CENTRAL IL INTO TO THE
MID AFTERNOON. WHILE THERE WILL BE ENOUGH MOISTURE AND LOW LEVEL
MOISTURE FLUX FOR LOCALLY HEAVY RAINFALL... THE CLUSTER SHOULD BE
MOVING WITH THE MID LEVEL FLOW...SO THE POTENTIAL FOR ORGANIZED
FLASH FLOODING DURING THIS TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/ECMWF...AND WAS AUGMENTED BY THE 00Z WRF ARW TO
BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN... INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. A SLIGHT RISK AREA WAS ISSUED TO COVER THE THREAT.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. PRECIPITABLE WATER VALUES FROM
NORTHERN
CA/SOUTHWEST OR THROUGH MUCH OF NV SHOULD TOP OUT BETWEEN TWO AND
THREE STANDARD DEVIATIONS ABOVE THE MEAN....AND MARGINAL
INSTABILITY SHOULD INITIATE CONVECTION MAINLY OVER THE TERRAIN.
SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE (LIKE THE 00Z
NAM CONEST) SUGGESTS THAT LOCAL 1.00+ INCH AMOUNTS ARE POSSIBLE
ACROSS THE TERRAIN OF CENTRAL NV. WITH A SHORT WAVE CROSSING THE
REGION FOR SYNOPTIC SCALE ASCENT...LOCAL QPF AMOUNTS OF THIS
MAGNITUDE ARE PLAUSIBLE. GIVEN THE HIGH MOISTURE CONTENT OF THE
AIR...A SEE TEXT WAS PLACED OVER NV.



DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT AT ALL.  THE 21Z SREF MEAN SHOWS
CAPE VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH
THE INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE
ROUNDS FOR PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A
BETTER OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH
FLOOD GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT
RAINFALL.  PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE
AREAS TO DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A
MODERATE RISK FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF
HAD A BETTER HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND
MIDWEST (EVEN WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS),
WITH THE 00Z UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z
GFS/00Z NAM/00Z UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE
WESTERN OK/TX BORDER, WHICH THE PAST COUPLE DAYS OF ECMWF RUNS
HAVE BEEN TRENDING TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
530 AM EDT SUN AUG 02 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/1200 UTC THRU AUG 05/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR



DAY 1...


...SOUTHEAST/FL...

DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL...GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS/ECMWF
CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A BIT
FURTHER NORTH...THE 00Z ECMWF A BIT FURTHER SOUTH). EACH SOLUTION
HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW AVERAGE
CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF. FOR
NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS IS
WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST MOVES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/ECMWF...THE HIGH RESOLUTION
GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM QPF. GIVEN
THE SPREAD IN PLACE... A SLIGHT RISK AREA WAS PLACED OVER MUCH OF
THE WESTERN PORTION OF THE PENINSULA FROM KTPA NORTHWEST INTO THE
BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN IA/NORTHERN AND CENTRAL IL INTO TO THE
MID AFTERNOON. WHILE THERE WILL BE ENOUGH MOISTURE AND LOW LEVEL
MOISTURE FLUX FOR LOCALLY HEAVY RAINFALL... THE CLUSTER SHOULD BE
MOVING WITH THE MID LEVEL FLOW...SO THE POTENTIAL FOR ORGANIZED
FLASH FLOODING DURING THIS TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/ECMWF...AND WAS AUGMENTED BY THE 00Z WRF ARW TO
BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN... INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. A SLIGHT RISK AREA WAS ISSUED TO COVER THE THREAT.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. PRECIPITABLE WATER VALUES FROM
NORTHERN
CA/SOUTHWEST OR THROUGH MUCH OF NV SHOULD TOP OUT BETWEEN TWO AND
THREE STANDARD DEVIATIONS ABOVE THE MEAN....AND MARGINAL
INSTABILITY SHOULD INITIATE CONVECTION MAINLY OVER THE TERRAIN.
SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE (LIKE THE 00Z
NAM CONEST) SUGGESTS THAT LOCAL 1.00+ INCH AMOUNTS ARE POSSIBLE
ACROSS THE TERRAIN OF CENTRAL NV. WITH A SHORT WAVE CROSSING THE
REGION FOR SYNOPTIC SCALE ASCENT...LOCAL QPF AMOUNTS OF THIS
MAGNITUDE ARE PLAUSIBLE. GIVEN THE HIGH MOISTURE CONTENT OF THE
AIR...A SEE TEXT WAS PLACED OVER NV.



DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT AT ALL.  THE 21Z SREF MEAN SHOWS
CAPE VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH
THE INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE
COMPLEXES NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE
ROUNDS FOR PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A
BETTER OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH
FLOOD GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT
RAINFALL.  PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE
AREAS TO DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A
MODERATE RISK FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE
COMPLEX NEAR KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF
HAD A BETTER HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND
MIDWEST (EVEN WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS),
WITH THE 00Z UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z
GFS/00Z NAM/00Z UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE
WESTERN OK/TX BORDER, WHICH THE PAST COUPLE DAYS OF ECMWF RUNS
HAVE BEEN TRENDING TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

...FL...

DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. A SLIGHT RISK AREA WAS PLACED OVER A
PORTION OF THE WEST COAST OF FL IN RESPONSE TO THE THREAT.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST SURGES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

THERE IS SOME SPREAD ON WHERE THE QPF MAXIMUM OCCURS. THIS SEEMS
TO BE TIED TO THE POSITION OF A SURFACE TROUGH ALONG THE WEST
COAST...AND THE LATITUDINAL DIFFERENCES RESULT IN A LOWER THAN
AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD BE NOTED THAT SOME OF
THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS THE 00Z WRF ARW AND 00Z
REGIONAL GEM...SHOW THE POTENTIAL FOR AN ADDITIONAL 6 TO 9 INCHES
OF RAINFALL WHERE TRAINING OCCURS. LIKE THE DIFFERENCES BETWEEN
THE 00Z GFS/ECMWF...THE HIGH RESOLUTION GUIDANCE ALSO SHOWS SPREAD
ON THE PLACEMENT OF MAXIMUM QPF. GIVEN THE SPREAD IN PLACE...A
SLIGHT RISK AREA WAS PLACED OVER MUCH OF THE WESTERN PORTION OF
THE PENINSULA FROM KTPA NORTHWEST INTO THE BIG BEND AREA.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE CROSSING THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED
TO PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION...WHICH COULD
PRODUCE HEAVY TO LOCALLY EXCESSIVE RAINFALL.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS)...NORTHERN NM AND SOUTHEAST UT. PRECIPITABLE WATER
VALUES HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS
ABOVE THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF
THE HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS
ARE POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND
BASED ON WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS
POSSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND NORTHERN NM SEEM TO BE IN THE
AREAS WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. A SLIGHT RISK AREA WAS ISSUED FOR THIS AREA.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. PRECIPITABLE WATER VALUES FROM
NORTHERN CA/SOUTHWEST OR THROUGH MUCH OF NV SHOULD TOP OUT BETWEEN
TWO AND THREE STANDARD DEVIATIONS ABOVE THE MEAN....AND MARGINAL
INSTABILITY SHOULD INITIATE CONVECTION MAINLY OVER THE TERRAIN.
SOME OF THE MORE AGGRESSIVE HIGH RESOLUTION GUIDANCE (LIKE THE 00Z
NAM CONEST) SUGGESTS THAT LOCAL 1.00+ INCH AMOUNTS ARE POSSIBLE
ACROSS THE TERRAIN OF CENTRAL NV. WITH A SHORT WAVE CROSSING THE
REGION FOR SYNOPTIC SCALE ASCENT...LOCAL QPF AMOUNTS OF THIS
MAGNITUDE ARE PLAUSIBLE. GIVEN THE HIGH MOISTURE CONTENT OF THE
AIR...A SEE TEXT WAS PLACED OVER NV.

VALID AUG 02/1200 UTC THRU AUG 05/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


SOUTHEAST/FL
~~~~~~~~~~~~
DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS AND 12Z
ECMWF CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A
BIT FURTHER NORTH...THE 12Z ECMWF A BIT FURTHER SOUTH). EACH
SOLUTION HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW
AVERAGE CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF.
FOR NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS
IS WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST SURGES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/12Z ECMWF...THE HIGH
RESOLUTION GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM
QPF. GIVEN THE SPREAD IN PLACE...A SLIGHT RISK AREA WILL BE PLACED
OVER MUCH OF THE WESTERN PORTION OF THE PENINSULA FROM KTPA
NORTHWEST INTO THE BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


MIDWEST/GREAT LAKES/OH VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN
IA/NORTHERN AND CENTRAL IL INTO TO THE MID AFTERNOON. WHILE THERE
WILL BE ENOUGH MOISTURE AND LOW LEVEL MOISTURE FLUX FOR LOCALLY
HEAVY RAINFALL... THE CLUSTER SHOULD BE MOVING WITH THE MID LEVEL
FLOW...SO THE POTENTIAL FOR ORGANIZED FLASH FLOODING DURING THIS
TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


WESTERN UNITED STATES
~~~~~~~~~~~~~~~~~~~~~
MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/12Z ECMWF...AND WAS AUGMENTED BY THE 00Z WRF
ARW TO BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/12Z ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. EITHER A SEE TEXT OR SMALL SLIGHT RISK AREA WILL BE
ISSUED FOR THIS AREA...WHICH MAY DEPEND ON COLLABORATION WITH
LOCAL OFFICES.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. AT THIS POINT...THE COVERAGE DOES NOT
APPEAR TO BE SUFFICIENT FOR A SLIGHT RISK AREA...BUT THIS WILL BE
MONITORED.


DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT.  THE 21Z SREF MEAN SHOWS CAPE
VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH THE
INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE COMPLEXES
NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE ROUNDS FOR
PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A BETTER
OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH FLOOD
GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT RAINFALL.
PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE AREAS TO
DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A MODERATE RISK
FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE COMPLEX NEAR
KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF HAD A BETTER
HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND MIDWEST (EVEN
WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS), WITH THE 00Z
UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z GFS/00Z NAM/00Z
UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE WESTERN OK/TX BORDER,
WHICH THE PAST COUPLE DAYS OF ECMWF RUNS HAVE BEEN TRENDING
TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD

PRELIM DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/1200 UTC THRU AUG 05/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


SOUTHEAST/FL
~~~~~~~~~~~~
DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS AND 12Z
ECMWF CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A
BIT FURTHER NORTH...THE 12Z ECMWF A BIT FURTHER SOUTH). EACH
SOLUTION HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW
AVERAGE CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF.
FOR NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS
IS WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST SURGES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/12Z ECMWF...THE HIGH
RESOLUTION GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM
QPF. GIVEN THE SPREAD IN PLACE...A SLIGHT RISK AREA WILL BE PLACED
OVER MUCH OF THE WESTERN PORTION OF THE PENINSULA FROM KTPA
NORTHWEST INTO THE BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


MIDWEST/GREAT LAKES/OH VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN
IA/NORTHERN AND CENTRAL IL INTO TO THE MID AFTERNOON. WHILE THERE
WILL BE ENOUGH MOISTURE AND LOW LEVEL MOISTURE FLUX FOR LOCALLY
HEAVY RAINFALL... THE CLUSTER SHOULD BE MOVING WITH THE MID LEVEL
FLOW...SO THE POTENTIAL FOR ORGANIZED FLASH FLOODING DURING THIS
TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


WESTERN UNITED STATES
~~~~~~~~~~~~~~~~~~~~~
MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/12Z ECMWF...AND WAS AUGMENTED BY THE 00Z WRF
ARW TO BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/12Z ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. EITHER A SEE TEXT OR SMALL SLIGHT RISK AREA WILL BE
ISSUED FOR THIS AREA...WHICH MAY DEPEND ON COLLABORATION WITH
LOCAL OFFICES.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. AT THIS POINT...THE COVERAGE DOES NOT
APPEAR TO BE SUFFICIENT FOR A SLIGHT RISK AREA...BUT THIS WILL BE
MONITORED.


DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT.  THE 21Z SREF MEAN SHOWS CAPE
VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH THE
INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE COMPLEXES
NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE ROUNDS FOR
PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A BETTER
OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH FLOOD
GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT RAINFALL.
PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE AREAS TO
DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A MODERATE RISK
FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE COMPLEX NEAR
KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF HAD A BETTER
HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND MIDWEST (EVEN
WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS), WITH THE 00Z
UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z GFS/00Z NAM/00Z
UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE WESTERN OK/TX BORDER,
WHICH THE PAST COUPLE DAYS OF ECMWF RUNS HAVE BEEN TRENDING
TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

PRELIM DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/1200 UTC THRU AUG 05/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


SOUTHEAST/FL
~~~~~~~~~~~~
DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS AND 12Z
ECMWF CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A
BIT FURTHER NORTH...THE 12Z ECMWF A BIT FURTHER SOUTH). EACH
SOLUTION HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW
AVERAGE CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF.
FOR NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS
IS WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST SURGES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/12Z ECMWF...THE HIGH
RESOLUTION GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM
QPF. GIVEN THE SPREAD IN PLACE...A SLIGHT RISK AREA WILL BE PLACED
OVER MUCH OF THE WESTERN PORTION OF THE PENINSULA FROM KTPA
NORTHWEST INTO THE BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


MIDWEST/GREAT LAKES/OH VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN
IA/NORTHERN AND CENTRAL IL INTO TO THE MID AFTERNOON. WHILE THERE
WILL BE ENOUGH MOISTURE AND LOW LEVEL MOISTURE FLUX FOR LOCALLY
HEAVY RAINFALL... THE CLUSTER SHOULD BE MOVING WITH THE MID LEVEL
FLOW...SO THE POTENTIAL FOR ORGANIZED FLASH FLOODING DURING THIS
TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


WESTERN UNITED STATES
~~~~~~~~~~~~~~~~~~~~~
MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/12Z ECMWF...AND WAS AUGMENTED BY THE 00Z WRF
ARW TO BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/12Z ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. EITHER A SEE TEXT OR SMALL SLIGHT RISK AREA WILL BE
ISSUED FOR THIS AREA...WHICH MAY DEPEND ON COLLABORATION WITH
LOCAL OFFICES.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. AT THIS POINT...THE COVERAGE DOES NOT
APPEAR TO BE SUFFICIENT FOR A SLIGHT RISK AREA...BUT THIS WILL BE
MONITORED.


DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT.  THE 21Z SREF MEAN SHOWS CAPE
VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH THE
INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE COMPLEXES
NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE ROUNDS FOR
PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A BETTER
OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH FLOOD
GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT RAINFALL.
PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE AREAS TO
DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A MODERATE RISK
FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE COMPLEX NEAR
KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF HAD A BETTER
HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND MIDWEST (EVEN
WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS), WITH THE 00Z
UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z GFS/00Z NAM/00Z
UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE WESTERN OK/TX BORDER,
WHICH THE PAST COUPLE DAYS OF ECMWF RUNS HAVE BEEN TRENDING
TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

VALID AUG 02/1200 UTC THRU AUG 05/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


SOUTHEAST/FL
~~~~~~~~~~~~
DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS AND 12Z
ECMWF CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A
BIT FURTHER NORTH...THE 12Z ECMWF A BIT FURTHER SOUTH). EACH
SOLUTION HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW
AVERAGE CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF.
FOR NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS
IS WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST SURGES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/12Z ECMWF...THE HIGH
RESOLUTION GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM
QPF. GIVEN THE SPREAD IN PLACE...A SLIGHT RISK AREA WILL BE PLACED
OVER MUCH OF THE WESTERN PORTION OF THE PENINSULA FROM KTPA
NORTHWEST INTO THE BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


MIDWEST/GREAT LAKES/OH VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN
IA/NORTHERN AND CENTRAL IL INTO TO THE MID AFTERNOON. WHILE THERE
WILL BE ENOUGH MOISTURE AND LOW LEVEL MOISTURE FLUX FOR LOCALLY
HEAVY RAINFALL... THE CLUSTER SHOULD BE MOVING WITH THE MID LEVEL
FLOW...SO THE POTENTIAL FOR ORGANIZED FLASH FLOODING DURING THIS
TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


WESTERN UNITED STATES
~~~~~~~~~~~~~~~~~~~~~
MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/12Z ECMWF...AND WAS AUGMENTED BY THE 00Z WRF
ARW TO BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/12Z ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. EITHER A SEE TEXT OR SMALL SLIGHT RISK AREA WILL BE
ISSUED FOR THIS AREA...WHICH MAY DEPEND ON COLLABORATION WITH
LOCAL OFFICES.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. AT THIS POINT...THE COVERAGE DOES NOT
APPEAR TO BE SUFFICIENT FOR A SLIGHT RISK AREA...BUT THIS WILL BE
MONITORED.


DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT.  THE 21Z SREF MEAN SHOWS CAPE
VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH THE
INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE COMPLEXES
NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE ROUNDS FOR
PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A BETTER
OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH FLOOD
GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT RAINFALL.
PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE AREAS TO
DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A MODERATE RISK
FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE COMPLEX NEAR
KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF HAD A BETTER
HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND MIDWEST (EVEN
WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS), WITH THE 00Z
UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z GFS/00Z NAM/00Z
UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE WESTERN OK/TX BORDER,
WHICH THE PAST COUPLE DAYS OF ECMWF RUNS HAVE BEEN TRENDING
TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

SOUTHEAST/FL
~~~~~~~~~~~~
DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS AND 12Z
ECMWF CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A
BIT FURTHER NORTH...THE 12Z ECMWF A BIT FURTHER SOUTH). EACH
SOLUTION HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW
AVERAGE CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIMUM QPF.
FOR NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS
IS WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST SURGES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/12Z ECMWF...THE HIGH
RESOLUTION GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM
QPF. GIVEN THE SPREAD IN PLACE...A SLIGHT RISK AREA WILL BE PLACED
OVER MUCH OF THE WESTERN PORTION OF THE PENINSULA FROM KTPA
NORTHWEST INTO THE BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


MIDWEST/GREAT LAKES/OH VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN
IA/NORTHERN AND CENTRAL IL INTO TO THE MID AFTERNOON. WHILE THERE
WILL BE ENOUGH MOISTURE AND LOW LEVEL MOISTURE FLUX FOR LOCALLY
HEAVY RAINFALL... THE CLUSTER SHOULD BE MOVING WITH THE MID LEVEL
FLOW...SO THE POTENTIAL FOR ORGANIZED FLASH FLOODING DURING THIS
TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


WESTERN UNITED STATES
~~~~~~~~~~~~~~~~~~~~~
MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/12Z ECMWF...AND WAS AUGMENTED BY THE 00Z WRF
ARW TO BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/12Z ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. EITHER A SEE TEXT OR SMALL SLIGHT RISK AREA WILL BE
ISSUED FOR THIS AREA...WHICH MAY DEPEND ON COLLABORATION WITH
LOCAL OFFICES.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. AT THIS POINT...THE COVERAGE DOES NOT
APPEAR TO BE SUFFICIENT FOR A SLIGHT RISK AREA...BUT THIS WILL BE
MONITORED.


DAYS 2/3...

ROCKIES/MONTANA
~~~~~~~~~~~~~~~
OF THE TWO DAYS, MONDAY APPEARS TO BE THE BETTER DAY FOR
AFTERNOON/EVENING CONVECTION ACROSS THIS REGION AS A SHORTWAVE
MOVING IN FROM THE PACIFIC HELPS SCOUR OUT THE REMAINING MOISTURE
FROM MUCH OF THE GREAT BASIN BY THE TIME TUESDAY AFTERNOON/EVENING
ROLLS AROUND, LEAVING THE NORTHERN CONTINENTAL DIVIDE AS THE
CENTER OF ACTION.  USED A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z
GFS HERE FOR THE MOST PART, OUTSIDE OF EASTERN MT WHERE THE LOWER
AMOUNTS OF THE 12Z/00Z ECMWF APPEARED MORE REASONABLE.
INSTABILITY IS PROGGED TO BE MINIMAL, SO THINK ANY FLASH FLOOD
THREAT WOULD BE ISOLATED ON MONDAY ACROSS THE INTERMOUNTAIN WEST.


PLAINS/MIDWEST/MS VALLEY
~~~~~~~~~~~~~~~~~~~~~~~~
COMBINED WITH THE USUAL NOCTURNAL LOW-LEVEL JET, A PAIR OF
SHORTWAVES MOVING OUT OF THE ROCKIES HELP INCREASE LOW-LEVEL
INFLOW ACROSS PORTIONS OF THE REGION.  CAPPING ACROSS THE REGION
IS QUITE MINIMAL, IF EXISTENT.  THE 21Z SREF MEAN SHOWS CAPE
VALUES RISING INTO THE 2000-3000 J/KG RANGE, WHICH ALONG WITH THE
INCREASING INSTABILITY SHOULD HELP DEVELOP CONVECTIVE COMPLEXES
NEAR THE WESTERN OK/TX BORDER, SD, AND TWO POSSIBLE ROUNDS FOR
PORTIONS OF KS, NE, AND MO.  TUESDAY APPEARS TO BE A BETTER
OVERALL SETUP THAN MONDAY FOR THESE COMPLEXES, BUT FLASH FLOOD
GUIDANCE IS RATHER LOW IN THIS REGION DUE TO RECENT RAINFALL.
PLACED SLIGHT RISKS OF EXCESSIVE RAINFALL ACROSS THESE AREAS TO
DEAL WITH THE FLASH FLOOD THREAT.  DECIDED AGAINST A MODERATE RISK
FOR TUESDAY AS EXACT PLACEMENT OF THE CONVECTIVE COMPLEX NEAR
KS/MO REMAINS UNCERTAIN.  THOUGHT THE 12Z/00Z ECMWF HAD A BETTER
HANDLE ON ACTIVITY ACROSS THE NORTHERN PLAINS AND MIDWEST (EVEN
WHEN CONSULTING THE 18Z AND 00Z GFS MASS FIELDS), WITH THE 00Z
UKMET HAVING SOME UTILITY ON TUESDAY.  THE 00Z GFS/00Z NAM/00Z
UKMET IDEAS SEEMED BETTER QPF-WISE NEAR THE WESTERN OK/TX BORDER,
WHICH THE PAST COUPLE DAYS OF ECMWF RUNS HAVE BEEN TRENDING
TOWARDS.


NORTHEAST
~~~~~~~~~
THUNDERSTORMS WITH MODERATE TO HEAVY RAINFALL ARE EXPECTED TO
IMPACT NORTHERN NEW ENGLAND AND PORTIONS OF NY MONDAY.  WHILE MASS
FIELDS IN THE GUIDANCE ARE SIMILAR, PROGRESSION ISSUES ARE SEEN IN
THE 00Z GFS AND 12Z/00Z ECMWF SOLUTIONS QPF-WISE.  HAVE LEANED ON
A COMPROMISE APPROACH BETWEEN THE TWO HERE SINCE THESE DIFFERENCES
WERE ALSO SEEN IN THE GUIDANCE AVAILABLE 24 HOURS AGO.  THE 21Z
SREF MEAN SHOWS CAPES >1000 J/KG WHILE THE 00Z GFS ADVERTISES 850
HPA INFLOW OF 30-50 KTS STREAMING INTO THE REGION.  THIS
COMBINATION SHOULD HELP ORGANIZE THUNDERSTORM ACTIVITY.  WHEN
CONSIDERING THE LOW FLASH FLOOD GUIDANCE IN NORTHERN NEW ENGLAND,
IT SEEMED PRUDENT TO REINTRODUCE A SLIGHT RISK OF EXCESSIVE
RAINFALL INTO THIS REGION.


FLORIDA/SOUTHEAST
~~~~~~~~~~~~~~~~~
A LOW PRESSURE AREA MOVING AWAY FROM THE REGION IS EXPECTED TO
CAUSE A NARROW AXIS OF HEAVY RAINFALL TO FALL DURING THE AFTERNOON
AND EVENING HOURS IN THE NORTH-CENTRAL PENINSULA.  LIGHT FLOW IN
THE SOUTHERN PENINSULA SHOULD LEAD TO SEA BREEZE CONVECTION
FOCUSING ACROSS THE INTERIOR/THE EVERGLADES/NEAR LAKE OKEECHOBEE.
USED A COMPROMISE OF THE 00Z GFS/12Z ECMWF FOR THE QPF PATTERN IN
THIS REGION.  A TIGHT RAINFALL GRADIENT IS ANTICIPATED ALONG THE
COASTS OF SC AND NC, SO ANY WESTWARD SHIFT OF THE LOW TRACK COULD
BRING AMOUNTS UP SUBSTANTIALLY.  STAY TUNED.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
225 AM EDT SUN AUG 02 2015


PRELIM DAY 1 QPF DISCUSSION
VALID AUG 02/1200 UTC THRU AUG 03/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


...SOUTHEAST/FL...

DEEP TROPICAL MOISTURE AND INSTABILITY WILL FEED SURGES OF
CONVECTION THAT TRACK ALONG A SURFACE TROUGH FROM THE EASTERN GULF
OF MEXICO ACROSS PORTIONS OF NORTHERN FL DURING DAY 1...PRODUCING
HEAVY TO EXCESSIVE RAINFALL. THE 00Z NAM APPEARS TO BE TOO QUICK
TO SCOUR THE MOISTURE AND DEVELOP A SURFACE WAVE ON THE
TROUGH...RESULTING INTO TOO LITTLE QPF FOR NORTHERN FL...GIVEN THE
MOISTURE PROFILE. THERE IS SOME SPREAD BETWEEN THE 00Z GFS AND 12Z
ECMWF CONCERNING THE POSITION OF THE MAXIMUM QPF (WITH 00Z GFS A
BIT FURTHER NORTH...THE 12Z ECMWF A BIT FURTHER SOUTH). EACH
SOLUTION HAS SUPPORT FROM OTHER MODELS...WHICH LEADS TO A BELOW
AVERAGE CONFIDENCE CONCERNING THE PLACEMENT OF THE MAXIUM QPF. FOR
NOW...A SOLUTION CLOSER TO THE 00Z GFS WAS PREFERRED...AS THIS IS
WHERE THE BEST LOW LEVEL CONVERGENCE IS EXPECTED.

THERE IS A LULL IN THE CONVECTION ACROSS PORTIONS OF NORTHERN AND
CENTRAL FL EARLY THIS MORNING...AS THE BEST MEAN LAYER INSTABILITY
REMAINS OFF THE WEST COAST OF THE PENINSULA. THE ACTIVITY SHOULD
REDEVELOP CLOSER TO 02/12Z...AS INSTABILITY INCREASES...AND THE
2.50 INCH PRECIPITABLE WATER PLUME OFF THE WEST COAST SURGES
EASTWARD. THE BEST LOW LEVEL MOISTURE FLUX IS CENTERED AROUND
02/18Z...AND SLOWLY TAILS OFF AFTER THAT TIME. THE BEST CONVECTION
IS EXPECTED BETWEEN 02/12Z AND 03/00Z...AFTER WHICH THE BEST LOW
AND MID LEVEL MOISTURE SHOULD BEGIN TO SLIDE TO THE EAST. THE HIGH
MOISTURE CONTENT OF THE AIR (ABOUT TWO STANDARD DEVIATIONS ABOVE
THE MEAN)...AS WELL AS THE POTENTIAL FOR TRAINING ACROSS PORTIONS
OF THE NORTHWEST PORTION OF THE PENINSULA...INDICATES THAT A BASIN
AVERAGE OF 3 TO 4 INCHES OF QPF SHOULD BE EXPECTED BETWEEN KCTY
AND KBKV.

AS MENTIONED EARLIER...THERE IS SOME SPREAD ON WHERE THE QPF
MAXIMUM OCCURS. THIS SEEMS TO BE TIED TO THE POSITION OF A SURFACE
TROUGH ALONG THE WEST COAST...AND THE LATITUDINAL DIFFERENCES
RESULT IN A LOWER THAN AVERAGE FORECAST FOR MAXIMUM QPF. IT SHOULD
BE NOTED THAT SOME OF THE 00Z HIGH RESOLUTION GUIDANCE...SUCH AS
THE 00Z WRF ARW AND 00Z REGIONAL GEM...SHOW THE POTENTIAL FOR AN
ADDITIONAL 6 TO 9 INCHES OF RAINFALL WHERE TRAINING OCCURS. LIKE
THE DIFFERENCES BETWEEN THE 00Z GFS/12Z ECMWF...THE HIGH
RESOLUTION GUIDANCE ALSO SHOWS SPREAD ON THE PLACEMENT OF MAXIMUM
QPF. GIVEN THE SPREAD IN PLACE...A SLIGHT RISK AREA WILL BE PLACED
OVER MUCH OF THE WESTERN PORTION OF THE PENINSULA FROM KTPA
NORTHWEST INTO THE BIG BEND AREA.

OVER THE EAST COAST OF FL...LOW LEVEL CONVERGENCE ALONG A SURFACE
BOUNDARY/SEA BREEZE SHOULD PROVIDE A FOCUS FOR CONVECTION FROM
KTTS THROUGH KFPR. THERE IS A MULTI MODEL SIGNAL FOR A SWATH OF
0.75 TO 1.00 INCHES OF QPF ALONG THIS AXIS. HIGH RESOLUTIONS
GUIDANCE (SUCH AS THE 00Z WRF NMMB) SUGGEST LOCALLY HIGHER AMOUNTS
(CLOSE TO 2.00 INCHES) ARE POSSIBLE.


...MIDWEST/GREAT LAKES/OH VALLEY...

MOISTURE AND INSTABILITY AHEAD OF A COLD FRONT CROSSING THE GREAT
LAKES AND MIDWEST DURING DAY 1 WILL FEED DEVELOPING
CONVECTION...WHICH MAY PRODUCE LOCALLY HEAVY RAINFALL...ESPECIALLY
ACROSS THE GREAT LAKES. THE 00Z NAM APPEARS TO BE TOO AGGRESSIVE
WITH THE DEVELOPMENT OF A SURFACE WAVE ON THE FRONT ACROSS
MI...WHICH LEADS TO STRONG LOW LEVEL CONVERGENCE AND A WELL
DEVELOPED CONVECTIVE LINE WITH HEAVY RAINFALL ACROSS THE LP OF MI.
THE 00Z GFS/12Z ECMWF APPEARED TO HAVE A BETTER HANDLE ON THE
TIMING AND STRENGTH OF THE FRONT...AND THE WPC QPF WAS BASED MORE
ON THIS BLEND.

THE FIRST BATCH OF CONVECTION DEVELOPS AHEAD OF A SHORT WAVE THAT
TRACKS OUT OF CENTRAL CANADA INTO THE GREAT LAKES BEFORE 02/18Z.
MOISTURE AND INSTABILITY AHEAD OF THE SHORT WAVE SHOULD BE
SUFFICIENT FOR A CLUSTER OF STRONG CONVECTION TO DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN
IA/NORTHERN AND CENTRAL IL INTO TO THE MID AFTERNOON. WHILE THERE
WILL BE ENOUGH MOISTURE AND LOW LEVEL MOISTURE FLUX FOR LOCALLY
HEAVY RAINFALL... THE CLUSTER SHOULD BE MOVING WITH THE MID LEVEL
FLOW...SO THE POTENTIAL FOR ORGANIZED FLASH FLOODING DURING THIS
TIME IS LOW.

THE MAIN THREAT FOR HEAVY RAINFALL COMES AFTER 02/18Z...AS A
STRONG SHORT WAVE DIVING SOUTH FROM CENTRAL CANADA CROSSES THE
UPPER GREAT LAKES. AHEAD OF THE SHORT WAVE AND SURFACE COLD
FRONT...A 40 TO 50 KNOT LOW LEVEL SOUTHWEST INFLOW TRANSPORTS
PRECIPITABLE WATER NEAR 1.50 INCHES INTO THE GREAT LAKES (MAINLY
WI/MI). MODEL SOUNDINGS SHOWED THAT INITIALLY DRY MID LEVELS
MOISTEN...SUGGESTING THAT THE COLUMN BECOMES MORE CONDUCIVE TO
HEAVY RAINFALL. THE MAIN THREAT FOR HEAVY RAINS SHOULD BE CENTERED
IN THE 30/00Z THROUGH 03/06Z TIME FRAME...AND A LARGE AREA OF 0.75
TO 1.25 INCHES OF QPF WAS PLACED OVER MI AND SOUTHEAST WI.

IT SHOULD BE NOTED THAT MOST GLOBAL/REGIONAL MODELS HAD MAXIMUM
QPF VALUES IN EXCESS OF 2.00 INCHES...THOUGH IN DIFFERENT
LOCATIONS (MAINLY ACROSS THE LP OF MI INTO NEARBY ONTARIO). THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE GENERALLY ABOVE 2.00
INCHES...AND THE 14 DAY PRECIPITATION TOTALS HAVE BEEN RELATIVELY
LIGHT...SUGGESTING DRY ANTECEDENT CONDITIONS. WHILE THE MOISTURE
PROFILE IS IMPRESSIVE...THE STORMS THAT DEVELOP SHOULD MOVE WITH
THE MID LEVEL FLOW...SO OUTSIDE OF TRAINING...THE THREAT FOR
ORGANIZED FLASH FLOODING APPEARS TO BE LOW.


...WESTERN UNITED STATES...

MONSOONAL MOISTURE CONTINUES TO SURGE INTO THE SOUTHWEST
STATES...AND PORTIONS OF THE MOISTURE ARE DIVERTED INTO THE GREAT
BASIN AND SOUTHERN PLAINS. THE HIGH MOISTURE CONTENT
AIR...COMBINED WITH MARGINAL INSTABILITY AND LIFT FROM A SHORT
WAVE ACROSS THE SOUTHERN ROCKIES AND GREAT BASIN...IS EXPECTED TO
PRODUCE AN AREA OF SCATTERED TO BROKEN CONVECTION ACROSS THE AREA.
CONVECTION COULD PRODUCE HEAVY TO LOCALLY EXCESSIVE
RAINFALL...ESPECIALLY ACROSS PORTIONS OF THE SOUTHERN ROCKIES AND
GREAT BASIN. FOR THE MOST PART...THERE WAS GOOD MODEL AGREEMENT
WITH THE OVERALL SYNOPTIC SETUP...INCLUDING THE PLACEMENT OF THE
SHORT WAVE. WITH THIS IN MIND...THE WPC QPF WAS BASED ON A BLEND
OF THE 00Z NAM/GFS/12Z ECMWF...AND WAS AUGMENTED BY THE 00Z WRF
ARW TO BETTER DEPICT HIGHER TERRAIN QPF MAXIMA.

CONVECTION CONTINUES TO DEVELOP ACROSS PORTIONS OF EASTERN NM
EARLY THIS MORNING...WHICH THEN TRACKS INTO NORTH TX. INSTABILITY
REMAINS IN PLACE ACROSS THE AREA...BUT THE LOW LEVELS CONTINUE TO
STABILIZE...SO ADDITIONAL DEVELOPMENT SHOULD BE ON THE NOSE OF LOW
LEVEL JET ACROSS WEST TX THROUGH 02/12Z OR SO. ADDITIONAL ACTIVITY
DOES NOT APPEAR TO HAVE ENOUGH INSTABILITY FOR A SUSTAINED HEAVY
RAIN THREAT. ADDITIONAL ACTIVITY IS EXPECTED ACROSS ACROSS EASTERN
NM DURING THE DAY ...AS PRECIPITABLE WATER VALUES NEAR AN INCH
FUEL CONVECTION THAT IS INITIALLY TIED TO THE TERRAIN.

CLUSTERS THAT DEVELOP IN EASTERN NM COULD SURVIVE INTO THE EVENING
HOURS...BEFORE FOLLOWING AN INSTABILITY AXIS ACROSS NORTH TX INTO
SOUTHWEST OK. THE LATEST NAM SIMULATED SATELLITE IMAGERY SUGGESTS
THAT A SMALL MCS COULD FORM ON THE NOSE OF A LOW LEVEL JET ACROSS
WEST TX IN THE 03/6Z TO 03/12Z TIME FRAME. WHILE AN MCS COULD
FORM...THERE IS NOT A STRONG MULTI MODEL SIGNAL FOR IT TO OCCUR.
THEREFORE...THE 00Z NAM MAY BE TOO HEAVY WITH ITS QPF ACROSS NORTH
TX...AND THE WPC QPF WAS BASED MORE CLOSELY ON A BLEND ON THE 00Z
GFS/12Z ECMWF HERE.

THE BEST THRUST OF MONSOONAL MOISTURE SHOULD OCCUR ACROSS NM INTO
THE SOUTHERN ROCKIES AND GREAT BASIN (AS SEEN ON THE LATEST HIGH
AND MID LEVEL LAYERED PRECIPITABLE WATER IMAGES). THERE IS GOOD
MODEL AGREEMENT THAT A SHORT WAVE TRACKS NORTH OUT OF AZ THROUGH
NV AND UT DURING THE AFTERNOON AND EVENING HOURS. THE SYNOPTIC
SCALE ASCENT ASSOCIATED WITH THE SHORT WAVE SHOULD ALLOW CLUSTERS
OF CONVECTION TO BLOSSOM ACROSS WESTERN CO (INCLUDING THE SAN JUAN
MOUNTAINS) INTO NEARBY SOUTHEAST UT. PRECIPITABLE WATER VALUES
HERE SHOULD RANGE BETWEEN TWO AND THREE STANDARD DEVIATIONS  ABOVE
THE MEAN...INCREASING THE THREAT FOR FLASH FLOODING. SOME OF THE
HIGH RESOLUTION GUIDANCE SUGGESTS LOCAL 2.00 INCH QPF AMOUNTS ARE
POSSIBLE WITH STORMS THAT TAP THE HIGH MOISTURE AIR...AND BASED ON
WHAT OCCURRED ACROSS WESTERN CO SAT...THIS SEEMS PLAUSIBLE.

THERE IS SOME UNCERTAINTY CONCERNING HOW WIDESPREAD THE HEAVY RAIN
THREAT WILL BE...BUT WESTERN CO AND SOUTHEAST UT SEEM TO BE IN THE
AREA WITH THE BEST COMBINATION OF LIFT/MOISTURE. WHILE BASIN
AVERAGE QPF AMOUNTS BETWEEN 0.25 AND 0.50 INCHES MAY BE COMMON IN
THE HIGHER TERRAIN...HIGHER AMOUNTS IN AREAS WHERE ONE AND THREE
HOUR FLASH FLOOD GUIDANCE VALUES ARE AN INCH OR LESS WILL CAUSE
PROBLEMS. EITHER A SEE TEXT OR SMALL SLIGHT RISK AREA WILL BE
ISSUED FOR THIS AREA...WHICH MAY DEPEND ON COLLABORATION WITH
LOCAL OFFICES.

FURTHER WEST...INSTABILITY AND MOISTURE COULD SUPPORT SCATTERED
CONVECTION WITH LOCALLY HEAVY RAINFALL ACROSS PORTIONS OF NV INTO
NORTHERN CA AND WESTERN OR. AT THIS POINT...THE COVERAGE DOES NOT
APPEAR TO BE SUFFICIENT FOR A SLIGHT RISK AREA...BUT THIS WILL BE
MONITORED.

EXCESSIVE RAINFALL DISCUSSION

852 PM EDT SAT AUG 01 2015

...VALID 01Z SUN AUG 02 2015 - 12Z SUN AUG 02 2015...
...REFERENCE AWIPS GRAPHIC UNDER...DAY 1 EXCESSIVE RAINFALL...


AFTER LOOKING AT THE 00Z RAOBS..AND RECENT SATELLITE AND RADAR
IMAGERY/TRENDS..PREVIOUS OUTLINED THREAT AREAS FOR POTENTIALLY
EXCESSIVE RAINS STILL APPEAR GOOD..SO SEE NO REASON TO DEVIATE
FROM THE EARLIER ISSUANCE.  THE NORTHERN FL PENINSULA STILL LOOKS
TO BE MOST FAVORED FOR MORE ORGANIZED HEAVY TO LOCALLY EXCESSIVE
RAINS..CONCENTRATED VICINITY OF THE LOW/MID LEVEL SHEAR AXIS AND
IN A PERSISTENT AND RATHER DEEP LAYERED ONSHORE FLOW REGIME.
PREVIOUS DISCUSSION FOLLOWS...

SLIGHT RISK OF RAINFALL EXCEEDING FFG TO THE RIGHT OF A LINE FROM

...FL...

THE SLIGHT RISK AREA IN FLORIDA WAS EXPANDED SOMEWHAT...TO INCLUDE
AREAS FARTHER SOUTH INTO THE TAMPA BAY AREA AND OVER THROUGH THE
CENTRAL PART OF THE PENINSULA. THE EXPECTATION IS THAT VERY HIGH
RAIN RATES ARE THE MAIN CONCERN...RATHER THAN PARTICULARLY
EXCESSIVE RAIN TOTALS. THE MODEL TRENDS HAVE BEEN TOWARD LESSER
EVENT TOTALS...AS CONVECTION WILL BE PRONE TO FORMING ALONG THE
COAST AND RADIATING OUT...QUICKLY PROPAGATING EAST THROUGH THE
MIXED BOUNDARY LAYER OVER THE PENINSULA...AND PROPAGATING MORE
SLOWLY WEST INTO THE BETTER INFLOW. WHILE THE POSSIBLITY FOR
EXTREME RAIN TOTALS...MORE THAN 5 INCHES POSSIBLE THROUGH
SUNDAY...REMAINS IN TACT NEAR THE COAST...THE OVERALL EVENT SHOULD
BE CHARACTERIZED MORE BY UNUSUALLY HIGH SHORT TERM RAIN RATES
GIVEN SUCH ANOMALOUS PW VALUES EXCEEDING 2.25 INCHES AT TIMES.


...PREVIOUS FL DISCUSSION...

A SLOWING FRONTAL BOUNDARY SHOULD BECOME QUASI STATIONARY ACROSS
PORTIONS OF THE SOUTHEAST STATES INTO THE WESTERN FL PANHANDLE.
THE FRONT SERVES TO FOCUS LOW LEVEL CONVERGENCE AND
INSTABILITY...WHICH TAPS DEEP TROPICAL MOISTURE (WITH PRECIPITABLE
WATER VALUES OF 2.25+ INCHES) TO PRODUCE CONVECTIVE CLUSTERS NEAR
THE FRONT...STRETCHING FROM ACROSS SOUTHEAST GA ACROSS NORTHERN FL
AND A PORTION OF THE WESTERN FL PANHANDLE. THE MID LEVEL STEERING
CURRENT IS FAIRLY WEAK...SUPPORTING SLOW CELL MOVEMENT ALONG THE
FRONT OVER THE ABOVEMENTIONED LOCATIONS. THE BEST CONCENTRATION OF
CONVECTIVE CLUSTERS IS EXPECTED ACROSS THE EASTERN FL PANHANDLE
ACROSS PORTIONS OF THE WEST COAST OF THE PENINSULA. OVER THIS
AREA...1.50 TO 3.00 INCHES OF QPF WAS PLACED...WITH THE HIGHEST
AMOUNTS BETWEEN KCTY AND KBKV.

THERE IS REMARKABLE CONSISTENCY AMONG THE VARIOUS 00Z
REGIONAL/GLOBAL SOLUTIONS PLACING 3.00 TO 4.00 INCHES OF QPF IN
THE ABOVEMENTIONED LOCATIONS. SOME OF THE 00Z HIGH RESOLUTION
MODEL SOLUTIONS PLACED MAXIMUM NEAR 8 INCHES (INCLUDING THE 00Z
WRF ARW/NMMB AND 00Z REGIONAL GEM..WHICH WAS CLOSER TO 11 INCHES
OF QPF) IN THIS AREA...OR JUST OFFSHORE. THESE AMOUNTS COULD BE
PLAUSIBLE...GIVEN THE DEEP MOISTURE IN PLACE AND SLOW
CELL/CLUSTER MOVEMENT. HOWEVER...SINCE THERE IS SOME SPREAD AS TO
WHETHER THE HIGHEST QPF AMOUNTS OCCUR JUST OFFSHORE OR ON LAND
OVER NORTHWEST FL...A MORE CONSERVATIVE APPROACH WAS USED FOR THE
WPC QPF. IN ANY EVENT...THE POTENTIAL FOR HIGH RAINFALL RATES AND
SLOW CELL MOTIONS NECESSITATE A SLIGHT RISK AREA FOR PORTIONS OF
NORTH FL.


...SOUTHWEST/GREAT BASIN...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS (SUCH AS THE 00Z
WRF ARW AND 00Z NAM CONEST) SUGGEST LOCAL AMOUNTS ABOVE 2
INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF THE VALUES THAT
THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD THREAT SHOULD BE
ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE DOWNPOURS SETTING
UP OVER PLACES THAT ARE MORE SUSCEPTIBLE.


...SOUTHERN HIGH PLAINS...

EARLY MORNING CONVECTION ACROSS NORTH TX SHOULD PRODUCE AN
MCV...WHICH CROSSES NORTH TX INTO SOUTHWEST OK THIS MORNING INTO
THE AFTERNOON. THE MCV SHOULD PROVIDE SUFFICIENT SUPPORT FOR
ADDITIONAL CONVECTION IN ITS PATH INTO THE AFTERNOON HOURS.
ADDITIONAL CONVECTION IS EXPECTED TO DEVELOP ACROSS NORTHEAST NM
THIS AFTERNOON AND EVENING...WHICH SHOULD FOLLOW THE SAME PATH AS
THE CONVECTION THIS MORNING...AS THE MID LEVEL RIDGE REMAINS IN
PLACE. AS THE LOW LEVEL FLOW INCREASES AGAIN ACROSS NORTH
TX/WESTERN OK/WESTERN KS AFTER 02/00Z...ADDITIONAL CONVECTION
COULD DEVELOP ON THE NOSE OF A LOW LEVEL JET NEAR 02/06Z ACROSS
NORTH TX...WHICH MOVES INTO SOUTHWEST OK. WHILE THERE IS SOME
MODEL COMMONALITY AMONG 00Z MODEL SOLUTIONS HERE...IT IT NOT CLEAR
IF A FULL BLOWN MCS DEVELOPS IN THE PRESENCE OF THE LOW LEVEL
JET...AS UPPER SUPPORT WILL BE LACKING...AND INFLOW OVERNIGHT WILL
COME FROM DRIER SOURCE REGIONS TO THE SOUTH OF THE SEMI-PERMANENT
WEAK FRONTAL ZONE.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
616 PM EDT SAT AUG 01 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/0000 UTC THRU AUG 05/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND ADJACENT STATES...

IT IS A WET PATTERN ACROSS FLORIDA...WITH A BROAD MID LEVEL TROUGH
AND WIDE ZONE OF VERY RICH MOISTURE TO EITHER SIDE OF THE TROUGH
AXIS. PRECIPITABLE WATER VALUES ARE RUNNING BETWEEN 1.9 AND 2.25
INCHES ON AVERAGE. THE LOW LEVEL REFLECTION / FRONTAL BOUNDARY
RELATED TO THE UPPER TROUGH IS STRETCHED WEST TO EAST ACROSS THE
GULF...WITH WEAK LOW PRESSURE TAKING SHAPE IN THE EASTERN GULF
CLOSE TO THE COAST OF NORTHWEST FLORIDA. GIVEN THE MOISTURE AND
THE PRESENCE OF THE TROUGH...WHICH PROMOTES A CORRIDOR OF ENHANCED
WIND FIELDS AND REPLENISHMENT OF STEEPER MID LEVEL LAPSE
RATES...THERE IS CONCERN OVER HEFTY RAIN RATES. EVOLUTION OF
INDIVIDUAL CONVECTIVE CELLS AND CLUSTERS...HOWEVER...MAKES THE
EVENT A LITTLE LESS PRONE TO WIDESPREAD EXCESSIVE RAINFALL.
CONVECTION FORMING OVER THE PENINSULA DURING THE DAY WILL
PROPAGATE QUICKLY EAST ACROSS THE LAND...CAUGHT UP IN MODERATE
SOUTHWESTERLY FLOW...AND THE WESTERN RING OF OUTFLOWS WILL
PROPAGATE MORE SLOWLY INTO THE INFLOW...PLACING QPF MAXIMA
GENERALLY OFFSHORE. ANY OF THIS ACTIVITY COULD PRODUCE BRIEF VERY
HEAVY RAIN RATES AND URBAN FLOODING. POTENTIAL FOR LONGER LASTING
HEAVY RAIN APPEARS LIMITED TO THE COAST...AND ESPECIALLY THE WEST
COAST OF FLORIDA...WITH CONVECTION FEEDING OFF THE LARGER
RESERVOIR OF MODERATE CAPE OVER THE GULF WATERS. THE RISK OF
EXCESSIVE RAINS IS GREATEST ALONG THE COAST FROM THE NORTH SIDE OF
TAMPA BAY THROUGH CEDAR KEY TO SAINT MARKS. THIS IS WHERE THE
CIRCULATION EMBEDDED WITHIN THE TROUGH IS FORECAST TO SHOW SLIGHT
DEEPENING...WITH MORE PERSISTENT VERTICAL MOTION HELPING TO
SUSTAIN HEAVY RAIN IN SPITE OF OUTFLOWS...ESPECIALLY LATE SATURDAY
NIGHT INTO SUNDAY.

OTHER DIURNAL ACTIVITY PRODUCING LOCALLY HEAVY RAIN IS EXPECTED IN
SOUTHERN SC TO SOUTHERN GA EACH DAY WHERE THE COLD FRONT HAD
FAILED TO PUSH TO THE COAST. WPC QPF HAD THIS REGION HANDLED
WELL...AND MINIMAL CHANGES WERE MADE...INCORPORATING THE 12Z
WRF-ARW AND NMM.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

THE REGION FROM THE HIGH PLAINS OF KS/NE TOWARD THE MIDWEST AND UP
INTO THE GREAT LAKES IS FORECAST TO EXPERIENCE SCATTERED OR
WIDESPREAD PRECIPITATION THROUGH SUNDAY AFTERNOON. THE MESOSCALE
DETAILS ARE DIFFICULT TO PIN DOWN GIVEN SUBTLE DIFFERENCES IN
MOISTURE DEPTH AND STRENGTH OF ASCENT STRETCHED ACROSS A
BACKGROUND OF OTHERWISE FAVORABLE LAPSE RATES AND LARGE SCALE
LIFT. JUDGING BY OBSERVATIONS...THE AXIS FROM EASTERN NE INTO
SOUTHERN IA AND NORTHERN MO SHOULD BE ACTIVE LATE TODAY AND
OVERNIGHT...WITH ADVECTION ON THE 310 K ISENTROPIC SURFACE NEAR
THE ENTRANCE REGION OF A STANDING 250 MB JET STREAK. ANOTHER
ACTIVE AXIS SHOULD BE FROM THE EASTERN DAKOTAS ACROSS SOUTHERN MN
ALONG A DEVELOPING WARM FRONT...AS A SHORTWAVE SHARPENS WITHIN
NORTHWESTERLY FLOW. A SECONDARY...STRONGER COLD FRONT WILL ALSO
ENTER NORTHERN ND/MN OVERNIGHT...RESULTING IN A THIRD RELATIVE
MAXIMUM OF ACTIVITY. ALL OF THIS SPREADS DOWNSTREAM INTO THE GREAT
LAKES ON SUNDAY...WITH BROAD WARM ADVECTION AND HEIGHT FALLS
SUPPORTING WIDESPREAD COVERAGE OF CONVECTION...ALTHOUGH MARGINAL
MOISTURE QUALITY AND RAPID MOVEMENT WOULD ARGUE AGAINST ANYTHING
TOO HEAVY IN THE AREAL AVERAGE QPF. THE MODEL SIGNALS SHOW
SIMILARITIES...BUT HAVE A NUMBER OF TIMING AND PLACEMENT
DISPARITIES...NOT THE LEAST OF WHICH IS THE FACT THAT SOME OF THE
12Z HI-RES MODELS INDICATE NO PRECIPITATION OVER NORTHERN IOWA
WHILE SOME OF THE GLOBAL GUIDANCE IS MAXIMIZED THERE. WPC SPLIT
THE DIFFERENCE TO SOME RESPECT...AS THE 310 K UPGLIDE MAY
INTERCEPT MOISTURE AND RESULT IN A PRECIP AXIS FARTHER
SOUTHWEST...BUT DEEP ASCENT AND MOISTURE CONVERGENCE INTO NORTHERN
IOWA SHOULD SUPPORT AT LEAST SOME PRECIPITATION. WE USED A BLEND
OF THE 12Z NAM CONEST...WRF-NMM...AND UKMET TO UPDATE THE FORECAST.


...WESTERN U.S...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS SUGGEST LOCAL
AMOUNTS ABOVE 2 INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF
THE VALUES THAT THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD
THREAT SHOULD BE ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE
DOWNPOURS SETTING UP OVER PLACES THAT ARE MORE SUSCEPTIBLE. FOR
QPF...THE NAM HAD A GOOD HANDLE ON THE SHEAR AXIS OVER AZ/NV...AND
ITS QPF LOOKED GOOD. WE USED A BLEND OF 40 PERCENT CONTINUITY WITH
50 PERCENT NAM AND 10 PERCENT GFS FOR AREAS WEST OF THE
CONTINENTAL DIVIDE. FOR AREAS EAST INTO CO/NM WE USED A SIMILAR
BLEND...BUT PREFERRED THE NAM CONUS NEST WHICH PICKED OUT MORE
DETAIL OVER COLORADO.


DAYS 2/3...

...PACIFIC NORTHWEST/NORTHERN ROCKIES/HIGH NORTHERN PLAINS...

THE MODELS SHOW A CYCLONIC CIRCULATION ACROSS THE PACIFIC WEST OF
CA SUPPORTS LOW LEVEL MOISTURE ADVECTION WITH CONVERGENCE
OCCURRING IN SOUTHERN OR SUN NIGHT WITH SHOWERS EXPECTED IN
SOUTHERN OR. ADDITIONAL LOW LEVEL CONVERGENCE MAXIMA DEVELOP WITH
A WAVE MOVING ONSHORE MON...PEAKING IN THE SOUTHERN OR CASCADES.
MANUAL QPF USED A BLEND OF THE 00Z-12Z ECMWF/12Z GFS/09Z SREF
MEAN.  THE 12Z UKMET WAS GIVEN LESS WEIGHT WITH ITS BULLS EYES
OVER WESTERN OR 12-21Z MON. A PAIR OF WAVES IMPACT THE REST OF THE
PACIFIC NORTHWEST AND NORTHERN ROCKIES...WITH ONE LEAD WAVE
DEPARTING THE ROCKIES ON TO THE NORTHERN PLAINS 12Z TUE WITH
SHOWERS DEVELOPING WITHIN THE 700 MB CONVERGENCE AXIS.  THE 12Z
NAM DEVELOPED A STRONGER CIRCULATION AFTER PRODUCING CONVECTION IN
WY MON NIGHT-EARLY TUE EXTENDING TO WESTERN SD...SO ITS AMOUNTS
APPEARED TO BE OVERDONE WITH POSSIBLE GRID SCALE FEEDBACK.
CONSEQUENTLY AMOUNTS ARE FCST TO BE LOWER THAN THE 12Z NAM.

...MIDWEST/GREAT LAKES/NORTHEAST...

A FRONTAL BOUNDARY AND PRE-FRONTAL LOW LEVEL CONVERGENCE ON THE
NOSE OF THE 850-700 MB JET HELP FOCUS RAINFALL.  THE WPC QPF USED
A CONSENSUS OF THE 00-12Z ECMWF/12Z GFS/12Z UKMET.  12Z NAM MI
AMOUNTS SHOULD NOT BE HIGH AS FORWARD PROPAGATION IS FAVORED BY
THE VEERING WIND PROFILES WITH TIME.
CONVECTION MOVES DOWNSTREAM INTO NY/PA AND NEW ENGLAND WITH
ENHANCEMENTS WHERE UPSLOPE FLOW DEVELOPS IN WINDWARD TERRAIN.  THE
FRONT REACHES THE COAST OF NEW ENGLAND ON TUE AND BEYOND INTO THE
OFFSHORE WATERS.
POST FRONTAL COLD ADVECTION DEVELOPS BUT MOST CONDITIONS PERSIST
SFC-700 MB AND LOW LEVEL ASCENT SUPPORT MORE SHOWERS IN THE NY
ADIRONDACKS AND VT GREEN MOUNTAINS.

...CENTRAL TO SOUTHERN ROCKIES EAST TO CENTRAL TO SOUTHERN
PLAINS...

ONE AREA OF SHOWERS/STORMS DEVELOPS WITHIN 850-700 MB THETA-E
ADVECTION AND FRONTOGENESIS IN A NORTHWEST SOUTHEAST AXIS
EXTENDING FROM THE WY/SD BORDER ACROSS NE AND THEN NORTHERN MO ON
DAY 3.
THE TRICK HERE IS THE MODELS DIFFER ON TIMING AND WHERE ANY
CIRCULATION CENTERS MAY DEVELOP WITHIN THE FRONTAL ZONE.

ON DAY 2...A 700 MB WAVE CROSSES OUT OF UT ACROSS CO AND NORTHERN
NM. ENHANCED MOISTURE AND LIFT ALONG AND AHEAD OF THE WAVE TRIGGER
SHOWERS AND STORMS ACROSS THE UT WASATCH AND THE RANGES OF CO DOWN
INTO NORTHEAST NM AND THEN THE HIGH PLAINS INTO THE TX PANHANDLE.
ON DAY 3 THIS WAVE CONTINUES NORTHEAST WITH SHOWERS AND STORMS
HEADING INTO OK/KS/MO.  THE DIFFER ON TIMING AND PHASING OF THE
700-500 MB WAVE SO A BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z
GFS/12Z NAM QPF WAS USED.

...SOUTHEAST/FLORIDA...

THE MODELS SHOW A PERSISTENT LOW LEVEL CIRCULATION WITH ENHANCED
MOISTURE AS BANDS OF 2.25 INCHES OF PRECIPITABLE WATER PERSIST OF
WEST CENTRAL FL.  LOCAL AMOUNTS OF 4-7" REMAIN POSSIBLE ALONG THE
COAST OF THE WESTERN FL PENINSULA SO SLIGHT RISK AREAS WERE
INCLUDED ON THE EXCESSIVE RAINFALL GRAPHICS EACH DAY.
THE AMOUNTS BEGIN TO TAPER AS THE LOW LEVEL CIRCULATION WEAKENS ON
DAY 3 AND PRESSURES RISE AS A RIDGE BUILDS ACROSS THE STATE.  WEAK
LOW LEVEL FLOW LEADS TO BOTH SEA BREEZES PROPAGATING INLAND WITH
INTERIOR SHOWERS/STORMS TUE AFTERNOON RESULTING FROM SEA BREEZE
AND LAKE BREEZE COLLISIONS.

THE 09Z SREF MEAN/12Z UKMET LOOK OVERDONE WITH AMOUNTS ACROSS
GA/SC/NC. THE 00-12Z UKMET RUNS HAVE BEEN TRYING TO SPIN UP
CONVECTIVE LOWS OVER THE SOUTHEAST WHICH INDUCES HEAVY RAINFALL
ALONG THE SOUTHEAST COAST. A COMPROMISE OF THE 00Z-12Z GFS/ECMWF
WAS USED IN THIS REGION...WITH THE 12Z CANADIAN GLOBAL ALSO USED
IN THE FL PENINSULA DAY 3.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
616 PM EDT SAT AUG 01 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/0000 UTC THRU AUG 05/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


MADE NO CHANGES TO THE PRELIM DAY 1 QPF.

DAY 1...

...FLORIDA AND ADJACENT STATES...

IT IS A WET PATTERN ACROSS FLORIDA...WITH A BROAD MID LEVEL TROUGH
AND WIDE ZONE OF VERY RICH MOISTURE TO EITHER SIDE OF THE TROUGH
AXIS. PRECIPITABLE WATER VALUES ARE RUNNING BETWEEN 1.9 AND 2.25
INCHES ON AVERAGE. THE LOW LEVEL REFLECTION / FRONTAL BOUNDARY
RELATED TO THE UPPER TROUGH IS STRETCHED WEST TO EAST ACROSS THE
GULF...WITH WEAK LOW PRESSURE TAKING SHAPE IN THE EASTERN GULF
CLOSE TO THE COAST OF NORTHWEST FLORIDA. GIVEN THE MOISTURE AND
THE PRESENCE OF THE TROUGH...WHICH PROMOTES A CORRIDOR OF ENHANCED
WIND FIELDS AND REPLENISHMENT OF STEEPER MID LEVEL LAPSE
RATES...THERE IS CONCERN OVER HEFTY RAIN RATES. EVOLUTION OF
INDIVIDUAL CONVECTIVE CELLS AND CLUSTERS...HOWEVER...MAKES THE
EVENT A LITTLE LESS PRONE TO WIDESPREAD EXCESSIVE RAINFALL.
CONVECTION FORMING OVER THE PENINSULA DURING THE DAY WILL
PROPAGATE QUICKLY EAST ACROSS THE LAND...CAUGHT UP IN MODERATE
SOUTHWESTERLY FLOW...AND THE WESTERN RING OF OUTFLOWS WILL
PROPAGATE MORE SLOWLY INTO THE INFLOW...PLACING QPF MAXIMA
GENERALLY OFFSHORE. ANY OF THIS ACTIVITY COULD PRODUCE BRIEF VERY
HEAVY RAIN RATES AND URBAN FLOODING. POTENTIAL FOR LONGER LASTING
HEAVY RAIN APPEARS LIMITED TO THE COAST...AND ESPECIALLY THE WEST
COAST OF FLORIDA...WITH CONVECTION FEEDING OFF THE LARGER
RESERVOIR OF MODERATE CAPE OVER THE GULF WATERS. THE RISK OF
EXCESSIVE RAINS IS GREATEST ALONG THE COAST FROM THE NORTH SIDE OF
TAMPA BAY THROUGH CEDAR KEY TO SAINT MARKS. THIS IS WHERE THE
CIRCULATION EMBEDDED WITHIN THE TROUGH IS FORECAST TO SHOW SLIGHT
DEEPENING...WITH MORE PERSISTENT VERTICAL MOTION HELPING TO
SUSTAIN HEAVY RAIN IN SPITE OF OUTFLOWS...ESPECIALLY LATE SATURDAY
NIGHT INTO SUNDAY.

OTHER DIURNAL ACTIVITY PRODUCING LOCALLY HEAVY RAIN IS EXPECTED IN
SOUTHERN SC TO SOUTHERN GA EACH DAY WHERE THE COLD FRONT HAD
FAILED TO PUSH TO THE COAST. WPC QPF HAD THIS REGION HANDLED
WELL...AND MINIMAL CHANGES WERE MADE...INCORPORATING THE 12Z
WRF-ARW AND NMM.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

THE REGION FROM THE HIGH PLAINS OF KS/NE TOWARD THE MIDWEST AND UP
INTO THE GREAT LAKES IS FORECAST TO EXPERIENCE SCATTERED OR
WIDESPREAD PRECIPITATION THROUGH SUNDAY AFTERNOON. THE MESOSCALE
DETAILS ARE DIFFICULT TO PIN DOWN GIVEN SUBTLE DIFFERENCES IN
MOISTURE DEPTH AND STRENGTH OF ASCENT STRETCHED ACROSS A
BACKGROUND OF OTHERWISE FAVORABLE LAPSE RATES AND LARGE SCALE
LIFT. JUDGING BY OBSERVATIONS...THE AXIS FROM EASTERN NE INTO
SOUTHERN IA AND NORTHERN MO SHOULD BE ACTIVE LATE TODAY AND
OVERNIGHT...WITH ADVECTION ON THE 310 K ISENTROPIC SURFACE NEAR
THE ENTRANCE REGION OF A STANDING 250 MB JET STREAK. ANOTHER
ACTIVE AXIS SHOULD BE FROM THE EASTERN DAKOTAS ACROSS SOUTHERN MN
ALONG A DEVELOPING WARM FRONT...AS A SHORTWAVE SHARPENS WITHIN
NORTHWESTERLY FLOW. A SECONDARY...STRONGER COLD FRONT WILL ALSO
ENTER NORTHERN ND/MN OVERNIGHT...RESULTING IN A THIRD RELATIVE
MAXIMUM OF ACTIVITY. ALL OF THIS SPREADS DOWNSTREAM INTO THE GREAT
LAKES ON SUNDAY...WITH BROAD WARM ADVECTION AND HEIGHT FALLS
SUPPORTING WIDESPREAD COVERAGE OF CONVECTION...ALTHOUGH MARGINAL
MOISTURE QUALITY AND RAPID MOVEMENT WOULD ARGUE AGAINST ANYTHING
TOO HEAVY IN THE AREAL AVERAGE QPF. THE MODEL SIGNALS SHOW
SIMILARITIES...BUT HAVE A NUMBER OF TIMING AND PLACEMENT
DISPARITIES...NOT THE LEAST OF WHICH IS THE FACT THAT SOME OF THE
12Z HI-RES MODELS INDICATE NO PRECIPITATION OVER NORTHERN IOWA
WHILE SOME OF THE GLOBAL GUIDANCE IS MAXIMIZED THERE. WPC SPLIT
THE DIFFERENCE TO SOME RESPECT...AS THE 310 K UPGLIDE MAY
INTERCEPT MOISTURE AND RESULT IN A PRECIP AXIS FARTHER
SOUTHWEST...BUT DEEP ASCENT AND MOISTURE CONVERGENCE INTO NORTHERN
IOWA SHOULD SUPPORT AT LEAST SOME PRECIPITATION. WE USED A BLEND
OF THE 12Z NAM CONEST...WRF-NMM...AND UKMET TO UPDATE THE FORECAST.


...WESTERN U.S...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS SUGGEST LOCAL
AMOUNTS ABOVE 2 INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF
THE VALUES THAT THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD
THREAT SHOULD BE ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE
DOWNPOURS SETTING UP OVER PLACES THAT ARE MORE SUSCEPTIBLE. FOR
QPF...THE NAM HAD A GOOD HANDLE ON THE SHEAR AXIS OVER AZ/NV...AND
ITS QPF LOOKED GOOD. WE USED A BLEND OF 40 PERCENT CONTINUITY WITH
50 PERCENT NAM AND 10 PERCENT GFS FOR AREAS WEST OF THE
CONTINENTAL DIVIDE. FOR AREAS EAST INTO CO/NM WE USED A SIMILAR
BLEND...BUT PREFERRED THE NAM CONUS NEST WHICH PICKED OUT MORE
DETAIL OVER COLORADO.


DAYS 2/3...

...PACIFIC NORTHWEST/NORTHERN ROCKIES/HIGH NORTHERN PLAINS...

THE MODELS SHOW A CYCLONIC CIRCULATION ACROSS THE PACIFIC WEST OF
CA SUPPORTS LOW LEVEL MOISTURE ADVECTION WITH CONVERGENCE
OCCURRING IN SOUTHERN OR SUN NIGHT WITH SHOWERS EXPECTED IN
SOUTHERN OR. ADDITIONAL LOW LEVEL CONVERGENCE MAXIMA DEVELOP WITH
A WAVE MOVING ONSHORE MON...PEAKING IN THE SOUTHERN OR CASCADES.
MANUAL QPF USED A BLEND OF THE 00Z-12Z ECMWF/12Z GFS/09Z SREF
MEAN.  THE 12Z UKMET WAS GIVEN LESS WEIGHT WITH ITS BULLS EYES
OVER WESTERN OR 12-21Z MON. A PAIR OF WAVES IMPACT THE REST OF THE
PACIFIC NORTHWEST AND NORTHERN ROCKIES...WITH ONE LEAD WAVE
DEPARTING THE ROCKIES ON TO THE NORTHERN PLAINS 12Z TUE WITH
SHOWERS DEVELOPING WITHIN THE 700 MB CONVERGENCE AXIS.  THE 12Z
NAM DEVELOPED A STRONGER CIRCULATION AFTER PRODUCING CONVECTION IN
WY MON NIGHT-EARLY TUE EXTENDING TO WESTERN SD...SO ITS AMOUNTS
APPEARED TO BE OVERDONE WITH POSSIBLE GRID SCALE FEEDBACK.
CONSEQUENTLY AMOUNTS ARE FCST TO BE LOWER THAN THE 12Z NAM.

...MIDWEST/GREAT LAKES/NORTHEAST...

A FRONTAL BOUNDARY AND PRE-FRONTAL LOW LEVEL CONVERGENCE ON THE
NOSE OF THE 850-700 MB JET HELP FOCUS RAINFALL.  THE WPC QPF USED
A CONSENSUS OF THE 00-12Z ECMWF/12Z GFS/12Z UKMET.  12Z NAM MI
AMOUNTS SHOULD NOT BE HIGH AS FORWARD PROPAGATION IS FAVORED BY
THE VEERING WIND PROFILES WITH TIME.
CONVECTION MOVES DOWNSTREAM INTO NY/PA AND NEW ENGLAND WITH
ENHANCEMENTS WHERE UPSLOPE FLOW DEVELOPS IN WINDWARD TERRAIN.  THE
FRONT REACHES THE COAST OF NEW ENGLAND ON TUE AND BEYOND INTO THE
OFFSHORE WATERS.
POST FRONTAL COLD ADVECTION DEVELOPS BUT MOST CONDITIONS PERSIST
SFC-700 MB AND LOW LEVEL ASCENT SUPPORT MORE SHOWERS IN THE NY
ADIRONDACKS AND VT GREEN MOUNTAINS.

...CENTRAL TO SOUTHERN ROCKIES EAST TO CENTRAL TO SOUTHERN
PLAINS...

ONE AREA OF SHOWERS/STORMS DEVELOPS WITHIN 850-700 MB THETA-E
ADVECTION AND FRONTOGENESIS IN A NORTHWEST SOUTHEAST AXIS
EXTENDING FROM THE WY/SD BORDER ACROSS NE AND THEN NORTHERN MO ON
DAY 3.
THE TRICK HERE IS THE MODELS DIFFER ON TIMING AND WHERE ANY
CIRCULATION CENTERS MAY DEVELOP WITHIN THE FRONTAL ZONE.

ON DAY 2...A 700 MB WAVE CROSSES OUT OF UT ACROSS CO AND NORTHERN
NM. ENHANCED MOISTURE AND LIFT ALONG AND AHEAD OF THE WAVE TRIGGER
SHOWERS AND STORMS ACROSS THE UT WASATCH AND THE RANGES OF CO DOWN
INTO NORTHEAST NM AND THEN THE HIGH PLAINS INTO THE TX PANHANDLE.
ON DAY 3 THIS WAVE CONTINUES NORTHEAST WITH SHOWERS AND STORMS
HEADING INTO OK/KS/MO.  THE DIFFER ON TIMING AND PHASING OF THE
700-500 MB WAVE SO A BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z
GFS/12Z NAM QPF WAS USED.

...SOUTHEAST/FLORIDA...

THE MODELS SHOW A PERSISTENT LOW LEVEL CIRCULATION WITH ENHANCED
MOISTURE AS BANDS OF 2.25 INCHES OF PRECIPITABLE WATER PERSIST OF
WEST CENTRAL FL.  LOCAL AMOUNTS OF 4-7" REMAIN POSSIBLE ALONG THE
COAST OF THE WESTERN FL PENINSULA SO SLIGHT RISK AREAS WERE
INCLUDED ON THE EXCESSIVE RAINFALL GRAPHICS EACH DAY.
THE AMOUNTS BEGIN TO TAPER AS THE LOW LEVEL CIRCULATION WEAKENS ON
DAY 3 AND PRESSURES RISE AS A RIDGE BUILDS ACROSS THE STATE.  WEAK
LOW LEVEL FLOW LEADS TO BOTH SEA BREEZES PROPAGATING INLAND WITH
INTERIOR SHOWERS/STORMS TUE AFTERNOON RESULTING FROM SEA BREEZE
AND LAKE BREEZE COLLISIONS.

THE 09Z SREF MEAN/12Z UKMET LOOK OVERDONE WITH AMOUNTS ACROSS
GA/SC/NC. THE 00-12Z UKMET RUNS HAVE BEEN TRYING TO SPIN UP
CONVECTIVE LOWS OVER THE SOUTHEAST WHICH INDUCES HEAVY RAINFALL
ALONG THE SOUTHEAST COAST. A COMPROMISE OF THE 00Z-12Z GFS/ECMWF
WAS USED IN THIS REGION...WITH THE 12Z CANADIAN GLOBAL ALSO USED
IN THE FL PENINSULA DAY 3.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
353 PM EDT SAT AUG 01 2015


PRELIM DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/0000 UTC THRU AUG 05/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR

DAY 1...

...FLORIDA AND ADJACENT STATES...

IT IS A WET PATTERN ACROSS FLORIDA...WITH A BROAD MID LEVEL TROUGH
AND WIDE ZONE OF VERY RICH MOISTURE TO EITHER SIDE OF THE TROUGH
AXIS. PRECIPITABLE WATER VALUES ARE RUNNING BETWEEN 1.9 AND 2.25
INCHES ON AVERAGE. THE LOW LEVEL REFLECTION / FRONTAL BOUNDARY
RELATED TO THE UPPER TROUGH IS STRETCHED WEST TO EAST ACROSS THE
GULF...WITH WEAK LOW PRESSURE TAKING SHAPE IN THE EASTERN GULF
CLOSE TO THE COAST OF NORTHWEST FLORIDA. GIVEN THE MOISTURE AND
THE PRESENCE OF THE TROUGH...WHICH PROMOTES A CORRIDOR OF ENHANCED
WIND FIELDS AND REPLENISHMENT OF STEEPER MID LEVEL LAPSE
RATES...THERE IS CONCERN OVER HEFTY RAIN RATES. EVOLUTION OF
INDIVIDUAL CONVECTIVE CELLS AND CLUSTERS...HOWEVER...MAKES THE
EVENT A LITTLE LESS PRONE TO WIDESPREAD EXCESSIVE RAINFALL.
CONVECTION FORMING OVER THE PENINSULA DURING THE DAY WILL
PROPAGATE QUICKLY EAST ACROSS THE LAND...CAUGHT UP IN MODERATE
SOUTHWESTERLY FLOW...AND THE WESTERN RING OF OUTFLOWS WILL
PROPAGATE MORE SLOWLY INTO THE INFLOW...PLACING QPF MAXIMA
GENERALLY OFFSHORE. ANY OF THIS ACTIVITY COULD PRODUCE BRIEF VERY
HEAVY RAIN RATES AND URBAN FLOODING. POTENTIAL FOR LONGER LASTING
HEAVY RAIN APPEARS LIMITED TO THE COAST...AND ESPECIALLY THE WEST
COAST OF FLORIDA...WITH CONVECTION FEEDING OFF THE LARGER
RESERVOIR OF MODERATE CAPE OVER THE GULF WATERS. THE RISK OF
EXCESSIVE RAINS IS GREATEST ALONG THE COAST FROM THE NORTH SIDE OF
TAMPA BAY THROUGH CEDAR KEY TO SAINT MARKS. THIS IS WHERE THE
CIRCULATION EMBEDDED WITHIN THE TROUGH IS FORECAST TO SHOW SLIGHT
DEEPENING...WITH MORE PERSISTENT VERTICAL MOTION HELPING TO
SUSTAIN HEAVY RAIN IN SPITE OF OUTFLOWS...ESPECIALLY LATE SATURDAY
NIGHT INTO SUNDAY.

OTHER DIURNAL ACTIVITY PRODUCING LOCALLY HEAVY RAIN IS EXPECTED IN
SOUTHERN SC TO SOUTHERN GA EACH DAY WHERE THE COLD FRONT HAD
FAILED TO PUSH TO THE COAST. WPC QPF HAD THIS REGION HANDLED
WELL...AND MINIMAL CHANGES WERE MADE...INCORPORATING THE 12Z
WRF-ARW AND NMM.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

THE REGION FROM THE HIGH PLAINS OF KS/NE TOWARD THE MIDWEST AND UP
INTO THE GREAT LAKES IS FORECAST TO EXPERIENCE SCATTERED OR
WIDESPREAD PRECIPITATION THROUGH SUNDAY AFTERNOON. THE MESOSCALE
DETAILS ARE DIFFICULT TO PIN DOWN GIVEN SUBTLE DIFFERENCES IN
MOISTURE DEPTH AND STRENGTH OF ASCENT STRETCHED ACROSS A
BACKGROUND OF OTHERWISE FAVORABLE LAPSE RATES AND LARGE SCALE
LIFT. JUDGING BY OBSERVATIONS...THE AXIS FROM EASTERN NE INTO
SOUTHERN IA AND NORTHERN MO SHOULD BE ACTIVE LATE TODAY AND
OVERNIGHT...WITH ADVECTION ON THE 310 K ISENTROPIC SURFACE NEAR
THE ENTRANCE REGION OF A STANDING 250 MB JET STREAK. ANOTHER
ACTIVE AXIS SHOULD BE FROM THE EASTERN DAKOTAS ACROSS SOUTHERN MN
ALONG A DEVELOPING WARM FRONT...AS A SHORTWAVE SHARPENS WITHIN
NORTHWESTERLY FLOW. A SECONDARY...STRONGER COLD FRONT WILL ALSO
ENTER NORTHERN ND/MN OVERNIGHT...RESULTING IN A THIRD RELATIVE
MAXIMUM OF ACTIVITY. ALL OF THIS SPREADS DOWNSTREAM INTO THE GREAT
LAKES ON SUNDAY...WITH BROAD WARM ADVECTION AND HEIGHT FALLS
SUPPORTING WIDESPREAD COVERAGE OF CONVECTION...ALTHOUGH MARGINAL
MOISTURE QUALITY AND RAPID MOVEMENT WOULD ARGUE AGAINST ANYTHING
TOO HEAVY IN THE AREAL AVERAGE QPF. THE MODEL SIGNALS SHOW
SIMILARITIES...BUT HAVE A NUMBER OF TIMING AND PLACEMENT
DISPARITIES...NOT THE LEAST OF WHICH IS THE FACT THAT SOME OF THE
12Z HI-RES MODELS INDICATE NO PRECIPITATION OVER NORTHERN IOWA
WHILE SOME OF THE GLOBAL GUIDANCE IS MAXIMIZED THERE. WPC SPLIT
THE DIFFERENCE TO SOME RESPECT...AS THE 310 K UPGLIDE MAY
INTERCEPT MOISTURE AND RESULT IN A PRECIP AXIS FARTHER
SOUTHWEST...BUT DEEP ASCENT AND MOISTURE CONVERGENCE INTO NORTHERN
IOWA SHOULD SUPPORT AT LEAST SOME PRECIPITATION. WE USED A BLEND
OF THE 12Z NAM CONEST...WRF-NMM...AND UKMET TO UPDATE THE FORECAST.


...WESTERN U.S...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS SUGGEST LOCAL
AMOUNTS ABOVE 2 INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF
THE VALUES THAT THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD
THREAT SHOULD BE ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE
DOWNPOURS SETTING UP OVER PLACES THAT ARE MORE SUSCEPTIBLE. FOR
QPF...THE NAM HAD A GOOD HANDLE ON THE SHEAR AXIS OVER AZ/NV...AND
ITS QPF LOOKED GOOD. WE USED A BLEND OF 40 PERCENT CONTINUITY WITH
50 PERCENT NAM AND 10 PERCENT GFS FOR AREAS WEST OF THE
CONTINENTAL DIVIDE. FOR AREAS EAST INTO CO/NM WE USED A SIMILAR
BLEND...BUT PREFERRED THE NAM CONUS NEST WHICH PICKED OUT MORE
DETAIL OVER COLORADO.

DAYS 2/3...

...PACIFIC NORTHWEST/NORTHERN ROCKIES/HIGH NORTHERN PLAINS...

THE MODELS SHOW A CYCLONIC CIRCULATION ACROSS THE PACIFIC WEST OF
CA SUPPORTS LOW LEVEL MOISTURE ADVECTION WITH CONVERGENCE
OCCURRING IN SOUTHERN OR SUN NIGHT WITH SHOWERS EXPECTED IN
SOUTHERN OR. ADDITIONAL LOW LEVEL CONVERGENCE MAXIMA DEVELOP WITH
A WAVE MOVING ONSHORE MON...PEAKING IN THE SOUTHERN OR CASCADES.
MANUAL QPF USED A BLEND OF THE 00Z-12Z ECMWF/12Z GFS/09Z SREF
MEAN.  THE 12Z UKMET WAS GIVEN LESS WEIGHT WITH ITS BULLS EYES
OVER WESTERN OR 12-21Z MON. A PAIR OF WAVES IMPACT THE REST OF THE
PACIFIC NORTHWEST AND NORTHERN ROCKIES...WITH ONE LEAD WAVE
DEPARTING THE ROCKIES ON TO THE NORTHERN PLAINS 12Z TUE WITH
SHOWERS DEVELOPING WITHIN THE 700 MB CONVERGENCE AXIS.  THE 12Z
NAM DEVELOPED A STRONGER CIRCULATION AFTER PRODUCING CONVECTION IN
WY MON NIGHT-EARLY TUE EXTENDING TO WESTERN SD...SO ITS AMOUNTS
APPEARED TO BE OVERDONE WITH POSSIBLE GRID SCALE FEEDBACK.
CONSEQUENTLY AMOUNTS ARE FCST TO BE LOWER THAN THE 12Z NAM.

...MIDWEST/GREAT LAKES/NORTHEAST...

A FRONTAL BOUNDARY AND PRE-FRONTAL LOW LEVEL CONVERGENCE ON THE
NOSE OF THE 850-700 MB JET HELP FOCUS RAINFALL.  THE WPC QPF USED
A CONSENSUS OF THE 00-12Z ECMWF/12Z GFS/12Z UKMET.  12Z NAM MI
AMOUNTS SHOULD NOT BE HIGH AS FORWARD PROPAGATION IS FAVORED BY
THE VEERING WIND PROFILES WITH TIME.
CONVECTION MOVES DOWNSTREAM INTO NY/PA AND NEW ENGLAND WITH
ENHANCEMENTS WHERE UPSLOPE FLOW DEVELOPS IN WINDWARD TERRAIN.  THE
FRONT REACHES THE COAST OF NEW ENGLAND ON TUE AND BEYOND INTO THE
OFFSHORE WATERS.
POST FRONTAL COLD ADVECTION DEVELOPS BUT MOST CONDITIONS PERSIST
SFC-700 MB AND LOW LEVEL ASCENT SUPPORT MORE SHOWERS IN THE NY
ADIRONDACKS AND VT GREEN MOUNTAINS.

...CENTRAL TO SOUTHERN ROCKIES EAST TO CENTRAL TO SOUTHERN
PLAINS...

ONE AREA OF SHOWERS/STORMS DEVELOPS WITHIN 850-700 MB THETA-E
ADVECTION AND FRONTOGENESIS IN A NORTHWEST SOUTHEAST AXIS
EXTENDING FROM THE WY/SD BORDER ACROSS NE AND THEN NORTHERN MO ON
DAY 3.
THE TRICK HERE IS THE MODELS DIFFER ON TIMING AND WHERE ANY
CIRCULATION CENTERS MAY DEVELOP WITHIN THE FRONTAL ZONE.

ON DAY 2...A 700 MB WAVE CROSSES OUT OF UT ACROSS CO AND NORTHERN
NM. ENHANCED MOISTURE AND LIFT ALONG AND AHEAD OF THE WAVE TRIGGER
SHOWERS AND STORMS ACROSS THE UT WASATCH AND THE RANGES OF CO DOWN
INTO NORTHEAST NM AND THEN THE HIGH PLAINS INTO THE TX PANHANDLE.
ON DAY 3 THIS WAVE CONTINUES NORTHEAST WITH SHOWERS AND STORMS
HEADING INTO OK/KS/MO.  THE DIFFER ON TIMING AND PHASING OF THE
700-500 MB WAVE SO A BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z
GFS/12Z NAM QPF WAS USED.

...SOUTHEAST/FLORIDA...

THE MODELS SHOW A PERSISTENT LOW LEVEL CIRCULATION WITH ENHANCED
MOISTURE AS BANDS OF 2.25 INCHES OF PRECIPITABLE WATER PERSIST OF
WEST CENTRAL FL.  LOCAL AMOUNTS OF 4-7" REMAIN POSSIBLE ALONG THE
COAST OF THE WESTERN FL PENINSULA SO SLIGHT RISK AREAS WERE
INCLUDED ON THE EXCESSIVE RAINFALL GRAPHICS EACH DAY.
THE AMOUNTS BEGIN TO TAPER AS THE LOW LEVEL CIRCULATION WEAKENS ON
DAY 3 AND PRESSURES RISE AS A RIDGE BUILDS ACROSS THE STATE.  WEAK
LOW LEVEL FLOW LEADS TO BOTH SEA BREEZES PROPAGATING INLAND WITH
INTERIOR SHOWERS/STORMS TUE AFTERNOON RESULTING FROM SEA BREEZE
AND LAKE BREEZE COLLISIONS.

THE 09Z SREF MEAN/12Z UKMET LOOK OVERDONE WITH AMOUNTS ACROSS
GA/SC/NC. THE 00-12Z UKMET RUNS HAVE BEEN TRYING TO SPIN UP
CONVECTIVE LOWS OVER THE SOUTHEAST WHICH INDUCES HEAVY RAINFALL
ALONG THE SOUTHEAST COAST. A COMPROMISE OF THE 00Z-12Z GFS/ECMWF
WAS USED IN THIS REGION...WITH THE 12Z CANADIAN GLOBAL ALSO USED
IN THE FL PENINSULA DAY 3.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
353 PM EDT SAT AUG 01 2015


PRELIM DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/0000 UTC THRU AUG 05/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR

DAY 1...

...FLORIDA AND ADJACENT STATES...

IT IS A WET PATTERN ACROSS FLORIDA...WITH A BROAD MID LEVEL TROUGH
AND WIDE ZONE OF VERY RICH MOISTURE TO EITHER SIDE OF THE TROUGH
AXIS. PRECIPITABLE WATER VALUES ARE RUNNING BETWEEN 1.9 AND 2.25
INCHES ON AVERAGE. THE LOW LEVEL REFLECTION / FRONTAL BOUNDARY
RELATED TO THE UPPER TROUGH IS STRETCHED WEST TO EAST ACROSS THE
GULF...WITH WEAK LOW PRESSURE TAKING SHAPE IN THE EASTERN GULF
CLOSE TO THE COAST OF NORTHWEST FLORIDA. GIVEN THE MOISTURE AND
THE PRESENCE OF THE TROUGH...WHICH PROMOTES A CORRIDOR OF ENHANCED
WIND FIELDS AND REPLENISHMENT OF STEEPER MID LEVEL LAPSE
RATES...THERE IS CONCERN OVER HEFTY RAIN RATES. EVOLUTION OF
INDIVIDUAL CONVECTIVE CELLS AND CLUSTERS...HOWEVER...MAKES THE
EVENT A LITTLE LESS PRONE TO WIDESPREAD EXCESSIVE RAINFALL.
CONVECTION FORMING OVER THE PENINSULA DURING THE DAY WILL
PROPAGATE QUICKLY EAST ACROSS THE LAND...CAUGHT UP IN MODERATE
SOUTHWESTERLY FLOW...AND THE WESTERN RING OF OUTFLOWS WILL
PROPAGATE MORE SLOWLY INTO THE INFLOW...PLACING QPF MAXIMA
GENERALLY OFFSHORE. ANY OF THIS ACTIVITY COULD PRODUCE BRIEF VERY
HEAVY RAIN RATES AND URBAN FLOODING. POTENTIAL FOR LONGER LASTING
HEAVY RAIN APPEARS LIMITED TO THE COAST...AND ESPECIALLY THE WEST
COAST OF FLORIDA...WITH CONVECTION FEEDING OFF THE LARGER
RESERVOIR OF MODERATE CAPE OVER THE GULF WATERS. THE RISK OF
EXCESSIVE RAINS IS GREATEST ALONG THE COAST FROM THE NORTH SIDE OF
TAMPA BAY THROUGH CEDAR KEY TO SAINT MARKS. THIS IS WHERE THE
CIRCULATION EMBEDDED WITHIN THE TROUGH IS FORECAST TO SHOW SLIGHT
DEEPENING...WITH MORE PERSISTENT VERTICAL MOTION HELPING TO
SUSTAIN HEAVY RAIN IN SPITE OF OUTFLOWS...ESPECIALLY LATE SATURDAY
NIGHT INTO SUNDAY.

OTHER DIURNAL ACTIVITY PRODUCING LOCALLY HEAVY RAIN IS EXPECTED IN
SOUTHERN SC TO SOUTHERN GA EACH DAY WHERE THE COLD FRONT HAD
FAILED TO PUSH TO THE COAST. WPC QPF HAD THIS REGION HANDLED
WELL...AND MINIMAL CHANGES WERE MADE...INCORPORATING THE 12Z
WRF-ARW AND NMM.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

THE REGION FROM THE HIGH PLAINS OF KS/NE TOWARD THE MIDWEST AND UP
INTO THE GREAT LAKES IS FORECAST TO EXPERIENCE SCATTERED OR
WIDESPREAD PRECIPITATION THROUGH SUNDAY AFTERNOON. THE MESOSCALE
DETAILS ARE DIFFICULT TO PIN DOWN GIVEN SUBTLE DIFFERENCES IN
MOISTURE DEPTH AND STRENGTH OF ASCENT STRETCHED ACROSS A
BACKGROUND OF OTHERWISE FAVORABLE LAPSE RATES AND LARGE SCALE
LIFT. JUDGING BY OBSERVATIONS...THE AXIS FROM EASTERN NE INTO
SOUTHERN IA AND NORTHERN MO SHOULD BE ACTIVE LATE TODAY AND
OVERNIGHT...WITH ADVECTION ON THE 310 K ISENTROPIC SURFACE NEAR
THE ENTRANCE REGION OF A STANDING 250 MB JET STREAK. ANOTHER
ACTIVE AXIS SHOULD BE FROM THE EASTERN DAKOTAS ACROSS SOUTHERN MN
ALONG A DEVELOPING WARM FRONT...AS A SHORTWAVE SHARPENS WITHIN
NORTHWESTERLY FLOW. A SECONDARY...STRONGER COLD FRONT WILL ALSO
ENTER NORTHERN ND/MN OVERNIGHT...RESULTING IN A THIRD RELATIVE
MAXIMUM OF ACTIVITY. ALL OF THIS SPREADS DOWNSTREAM INTO THE GREAT
LAKES ON SUNDAY...WITH BROAD WARM ADVECTION AND HEIGHT FALLS
SUPPORTING WIDESPREAD COVERAGE OF CONVECTION...ALTHOUGH MARGINAL
MOISTURE QUALITY AND RAPID MOVEMENT WOULD ARGUE AGAINST ANYTHING
TOO HEAVY IN THE AREAL AVERAGE QPF. THE MODEL SIGNALS SHOW
SIMILARITIES...BUT HAVE A NUMBER OF TIMING AND PLACEMENT
DISPARITIES...NOT THE LEAST OF WHICH IS THE FACT THAT SOME OF THE
12Z HI-RES MODELS INDICATE NO PRECIPITATION OVER NORTHERN IOWA
WHILE SOME OF THE GLOBAL GUIDANCE IS MAXIMIZED THERE. WPC SPLIT
THE DIFFERENCE TO SOME RESPECT...AS THE 310 K UPGLIDE MAY
INTERCEPT MOISTURE AND RESULT IN A PRECIP AXIS FARTHER
SOUTHWEST...BUT DEEP ASCENT AND MOISTURE CONVERGENCE INTO NORTHERN
IOWA SHOULD SUPPORT AT LEAST SOME PRECIPITATION. WE USED A BLEND
OF THE 12Z NAM CONEST...WRF-NMM...AND UKMET TO UPDATE THE FORECAST.


...WESTERN U.S...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS SUGGEST LOCAL
AMOUNTS ABOVE 2 INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF
THE VALUES THAT THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD
THREAT SHOULD BE ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE
DOWNPOURS SETTING UP OVER PLACES THAT ARE MORE SUSCEPTIBLE. FOR
QPF...THE NAM HAD A GOOD HANDLE ON THE SHEAR AXIS OVER AZ/NV...AND
ITS QPF LOOKED GOOD. WE USED A BLEND OF 40 PERCENT CONTINUITY WITH
50 PERCENT NAM AND 10 PERCENT GFS FOR AREAS WEST OF THE
CONTINENTAL DIVIDE. FOR AREAS EAST INTO CO/NM WE USED A SIMILAR
BLEND...BUT PREFERRED THE NAM CONUS NEST WHICH PICKED OUT MORE
DETAIL OVER COLORADO.

DAYS 2/3...

...PACIFIC NORTHWEST/NORTHERN ROCKIES/HIGH NORTHERN PLAINS...

THE MODELS SHOW A CYCLONIC CIRCULATION ACROSS THE PACIFIC WEST OF
CA SUPPORTS LOW LEVEL MOISTURE ADVECTION WITH CONVERGENCE
OCCURRING IN SOUTHERN OR SUN NIGHT WITH SHOWERS EXPECTED IN
SOUTHERN OR. ADDITIONAL LOW LEVEL CONVERGENCE MAXIMA DEVELOP WITH
A WAVE MOVING ONSHORE MON...PEAKING IN THE SOUTHERN OR CASCADES.
MANUAL QPF USED A BLEND OF THE 00Z-12Z ECMWF/12Z GFS/09Z SREF
MEAN.  THE 12Z UKMET WAS GIVEN LESS WEIGHT WITH ITS BULLS EYES
OVER WESTERN OR 12-21Z MON. A PAIR OF WAVES IMPACT THE REST OF THE
PACIFIC NORTHWEST AND NORTHERN ROCKIES...WITH ONE LEAD WAVE
DEPARTING THE ROCKIES ON TO THE NORTHERN PLAINS 12Z TUE WITH
SHOWERS DEVELOPING WITHIN THE 700 MB CONVERGENCE AXIS.  THE 12Z
NAM DEVELOPED A STRONGER CIRCULATION AFTER PRODUCING CONVECTION IN
WY MON NIGHT-EARLY TUE EXTENDING TO WESTERN SD...SO ITS AMOUNTS
APPEARED TO BE OVERDONE WITH POSSIBLE GRID SCALE FEEDBACK.
CONSEQUENTLY AMOUNTS ARE FCST TO BE LOWER THAN THE 12Z NAM.

...MIDWEST/GREAT LAKES/NORTHEAST...

A FRONTAL BOUNDARY AND PRE-FRONTAL LOW LEVEL CONVERGENCE ON THE
NOSE OF THE 850-700 MB JET HELP FOCUS RAINFALL.  THE WPC QPF USED
A CONSENSUS OF THE 00-12Z ECMWF/12Z GFS/12Z UKMET.  12Z NAM MI
AMOUNTS SHOULD NOT BE HIGH AS FORWARD PROPAGATION IS FAVORED BY
THE VEERING WIND PROFILES WITH TIME.
CONVECTION MOVES DOWNSTREAM INTO NY/PA AND NEW ENGLAND WITH
ENHANCEMENTS WHERE UPSLOPE FLOW DEVELOPS IN WINDWARD TERRAIN.  THE
FRONT REACHES THE COAST OF NEW ENGLAND ON TUE AND BEYOND INTO THE
OFFSHORE WATERS.
POST FRONTAL COLD ADVECTION DEVELOPS BUT MOST CONDITIONS PERSIST
SFC-700 MB AND LOW LEVEL ASCENT SUPPORT MORE SHOWERS IN THE NY
ADIRONDACKS AND VT GREEN MOUNTAINS.

...CENTRAL TO SOUTHERN ROCKIES EAST TO CENTRAL TO SOUTHERN
PLAINS...

ONE AREA OF SHOWERS/STORMS DEVELOPS WITHIN 850-700 MB THETA-E
ADVECTION AND FRONTOGENESIS IN A NORTHWEST SOUTHEAST AXIS
EXTENDING FROM THE WY/SD BORDER ACROSS NE AND THEN NORTHERN MO ON
DAY 3.
THE TRICK HERE IS THE MODELS DIFFER ON TIMING AND WHERE ANY
CIRCULATION CENTERS MAY DEVELOP WITHIN THE FRONTAL ZONE.

ON DAY 2...A 700 MB WAVE CROSSES OUT OF UT ACROSS CO AND NORTHERN
NM. ENHANCED MOISTURE AND LIFT ALONG AND AHEAD OF THE WAVE TRIGGER
SHOWERS AND STORMS ACROSS THE UT WASATCH AND THE RANGES OF CO DOWN
INTO NORTHEAST NM AND THEN THE HIGH PLAINS INTO THE TX PANHANDLE.
ON DAY 3 THIS WAVE CONTINUES NORTHEAST WITH SHOWERS AND STORMS
HEADING INTO OK/KS/MO.  THE DIFFER ON TIMING AND PHASING OF THE
700-500 MB WAVE SO A BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z
GFS/12Z NAM QPF WAS USED.

...SOUTHEAST/FLORIDA...

THE MODELS SHOW A PERSISTENT LOW LEVEL CIRCULATION WITH ENHANCED
MOISTURE AS BANDS OF 2.25 INCHES OF PRECIPITABLE WATER PERSIST OF
WEST CENTRAL FL.  LOCAL AMOUNTS OF 4-7" REMAIN POSSIBLE ALONG THE
COAST OF THE WESTERN FL PENINSULA SO SLIGHT RISK AREAS WERE
INCLUDED ON THE EXCESSIVE RAINFALL GRAPHICS EACH DAY.
THE AMOUNTS BEGIN TO TAPER AS THE LOW LEVEL CIRCULATION WEAKENS ON
DAY 3 AND PRESSURES RISE AS A RIDGE BUILDS ACROSS THE STATE.  WEAK
LOW LEVEL FLOW LEADS TO BOTH SEA BREEZES PROPAGATING INLAND WITH
INTERIOR SHOWERS/STORMS TUE AFTERNOON RESULTING FROM SEA BREEZE
AND LAKE BREEZE COLLISIONS.

THE 09Z SREF MEAN/12Z UKMET LOOK OVERDONE WITH AMOUNTS ACROSS
GA/SC/NC. THE 00-12Z UKMET RUNS HAVE BEEN TRYING TO SPIN UP
CONVECTIVE LOWS OVER THE SOUTHEAST WHICH INDUCES HEAVY RAINFALL
ALONG THE SOUTHEAST COAST. A COMPROMISE OF THE 00Z-12Z GFS/ECMWF
WAS USED IN THIS REGION...WITH THE 12Z CANADIAN GLOBAL ALSO USED
IN THE FL PENINSULA DAY 3.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
353 PM EDT SAT AUG 01 2015


PRELIM DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 02/0000 UTC THRU AUG 05/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR

DAY 1...

...FLORIDA AND ADJACENT STATES...

IT IS A WET PATTERN ACROSS FLORIDA...WITH A BROAD MID LEVEL TROUGH
AND WIDE ZONE OF VERY RICH MOISTURE TO EITHER SIDE OF THE TROUGH
AXIS. PRECIPITABLE WATER VALUES ARE RUNNING BETWEEN 1.9 AND 2.25
INCHES ON AVERAGE. THE LOW LEVEL REFLECTION / FRONTAL BOUNDARY
RELATED TO THE UPPER TROUGH IS STRETCHED WEST TO EAST ACROSS THE
GULF...WITH WEAK LOW PRESSURE TAKING SHAPE IN THE EASTERN GULF
CLOSE TO THE COAST OF NORTHWEST FLORIDA. GIVEN THE MOISTURE AND
THE PRESENCE OF THE TROUGH...WHICH PROMOTES A CORRIDOR OF ENHANCED
WIND FIELDS AND REPLENISHMENT OF STEEPER MID LEVEL LAPSE
RATES...THERE IS CONCERN OVER HEFTY RAIN RATES. EVOLUTION OF
INDIVIDUAL CONVECTIVE CELLS AND CLUSTERS...HOWEVER...MAKES THE
EVENT A LITTLE LESS PRONE TO WIDESPREAD EXCESSIVE RAINFALL.
CONVECTION FORMING OVER THE PENINSULA DURING THE DAY WILL
PROPAGATE QUICKLY EAST ACROSS THE LAND...CAUGHT UP IN MODERATE
SOUTHWESTERLY FLOW...AND THE WESTERN RING OF OUTFLOWS WILL
PROPAGATE MORE SLOWLY INTO THE INFLOW...PLACING QPF MAXIMA
GENERALLY OFFSHORE. ANY OF THIS ACTIVITY COULD PRODUCE BRIEF VERY
HEAVY RAIN RATES AND URBAN FLOODING. POTENTIAL FOR LONGER LASTING
HEAVY RAIN APPEARS LIMITED TO THE COAST...AND ESPECIALLY THE WEST
COAST OF FLORIDA...WITH CONVECTION FEEDING OFF THE LARGER
RESERVOIR OF MODERATE CAPE OVER THE GULF WATERS. THE RISK OF
EXCESSIVE RAINS IS GREATEST ALONG THE COAST FROM THE NORTH SIDE OF
TAMPA BAY THROUGH CEDAR KEY TO SAINT MARKS. THIS IS WHERE THE
CIRCULATION EMBEDDED WITHIN THE TROUGH IS FORECAST TO SHOW SLIGHT
DEEPENING...WITH MORE PERSISTENT VERTICAL MOTION HELPING TO
SUSTAIN HEAVY RAIN IN SPITE OF OUTFLOWS...ESPECIALLY LATE SATURDAY
NIGHT INTO SUNDAY.

OTHER DIURNAL ACTIVITY PRODUCING LOCALLY HEAVY RAIN IS EXPECTED IN
SOUTHERN SC TO SOUTHERN GA EACH DAY WHERE THE COLD FRONT HAD
FAILED TO PUSH TO THE COAST. WPC QPF HAD THIS REGION HANDLED
WELL...AND MINIMAL CHANGES WERE MADE...INCORPORATING THE 12Z
WRF-ARW AND NMM.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

THE REGION FROM THE HIGH PLAINS OF KS/NE TOWARD THE MIDWEST AND UP
INTO THE GREAT LAKES IS FORECAST TO EXPERIENCE SCATTERED OR
WIDESPREAD PRECIPITATION THROUGH SUNDAY AFTERNOON. THE MESOSCALE
DETAILS ARE DIFFICULT TO PIN DOWN GIVEN SUBTLE DIFFERENCES IN
MOISTURE DEPTH AND STRENGTH OF ASCENT STRETCHED ACROSS A
BACKGROUND OF OTHERWISE FAVORABLE LAPSE RATES AND LARGE SCALE
LIFT. JUDGING BY OBSERVATIONS...THE AXIS FROM EASTERN NE INTO
SOUTHERN IA AND NORTHERN MO SHOULD BE ACTIVE LATE TODAY AND
OVERNIGHT...WITH ADVECTION ON THE 310 K ISENTROPIC SURFACE NEAR
THE ENTRANCE REGION OF A STANDING 250 MB JET STREAK. ANOTHER
ACTIVE AXIS SHOULD BE FROM THE EASTERN DAKOTAS ACROSS SOUTHERN MN
ALONG A DEVELOPING WARM FRONT...AS A SHORTWAVE SHARPENS WITHIN
NORTHWESTERLY FLOW. A SECONDARY...STRONGER COLD FRONT WILL ALSO
ENTER NORTHERN ND/MN OVERNIGHT...RESULTING IN A THIRD RELATIVE
MAXIMUM OF ACTIVITY. ALL OF THIS SPREADS DOWNSTREAM INTO THE GREAT
LAKES ON SUNDAY...WITH BROAD WARM ADVECTION AND HEIGHT FALLS
SUPPORTING WIDESPREAD COVERAGE OF CONVECTION...ALTHOUGH MARGINAL
MOISTURE QUALITY AND RAPID MOVEMENT WOULD ARGUE AGAINST ANYTHING
TOO HEAVY IN THE AREAL AVERAGE QPF. THE MODEL SIGNALS SHOW
SIMILARITIES...BUT HAVE A NUMBER OF TIMING AND PLACEMENT
DISPARITIES...NOT THE LEAST OF WHICH IS THE FACT THAT SOME OF THE
12Z HI-RES MODELS INDICATE NO PRECIPITATION OVER NORTHERN IOWA
WHILE SOME OF THE GLOBAL GUIDANCE IS MAXIMIZED THERE. WPC SPLIT
THE DIFFERENCE TO SOME RESPECT...AS THE 310 K UPGLIDE MAY
INTERCEPT MOISTURE AND RESULT IN A PRECIP AXIS FARTHER
SOUTHWEST...BUT DEEP ASCENT AND MOISTURE CONVERGENCE INTO NORTHERN
IOWA SHOULD SUPPORT AT LEAST SOME PRECIPITATION. WE USED A BLEND
OF THE 12Z NAM CONEST...WRF-NMM...AND UKMET TO UPDATE THE FORECAST.


...WESTERN U.S...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS SUGGEST LOCAL
AMOUNTS ABOVE 2 INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF
THE VALUES THAT THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD
THREAT SHOULD BE ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE
DOWNPOURS SETTING UP OVER PLACES THAT ARE MORE SUSCEPTIBLE. FOR
QPF...THE NAM HAD A GOOD HANDLE ON THE SHEAR AXIS OVER AZ/NV...AND
ITS QPF LOOKED GOOD. WE USED A BLEND OF 40 PERCENT CONTINUITY WITH
50 PERCENT NAM AND 10 PERCENT GFS FOR AREAS WEST OF THE
CONTINENTAL DIVIDE. FOR AREAS EAST INTO CO/NM WE USED A SIMILAR
BLEND...BUT PREFERRED THE NAM CONUS NEST WHICH PICKED OUT MORE
DETAIL OVER COLORADO.

DAYS 2/3...

...PACIFIC NORTHWEST/NORTHERN ROCKIES/HIGH NORTHERN PLAINS...

THE MODELS SHOW A CYCLONIC CIRCULATION ACROSS THE PACIFIC WEST OF
CA SUPPORTS LOW LEVEL MOISTURE ADVECTION WITH CONVERGENCE
OCCURRING IN SOUTHERN OR SUN NIGHT WITH SHOWERS EXPECTED IN
SOUTHERN OR. ADDITIONAL LOW LEVEL CONVERGENCE MAXIMA DEVELOP WITH
A WAVE MOVING ONSHORE MON...PEAKING IN THE SOUTHERN OR CASCADES.
MANUAL QPF USED A BLEND OF THE 00Z-12Z ECMWF/12Z GFS/09Z SREF
MEAN.  THE 12Z UKMET WAS GIVEN LESS WEIGHT WITH ITS BULLS EYES
OVER WESTERN OR 12-21Z MON. A PAIR OF WAVES IMPACT THE REST OF THE
PACIFIC NORTHWEST AND NORTHERN ROCKIES...WITH ONE LEAD WAVE
DEPARTING THE ROCKIES ON TO THE NORTHERN PLAINS 12Z TUE WITH
SHOWERS DEVELOPING WITHIN THE 700 MB CONVERGENCE AXIS.  THE 12Z
NAM DEVELOPED A STRONGER CIRCULATION AFTER PRODUCING CONVECTION IN
WY MON NIGHT-EARLY TUE EXTENDING TO WESTERN SD...SO ITS AMOUNTS
APPEARED TO BE OVERDONE WITH POSSIBLE GRID SCALE FEEDBACK.
CONSEQUENTLY AMOUNTS ARE FCST TO BE LOWER THAN THE 12Z NAM.

...MIDWEST/GREAT LAKES/NORTHEAST...

A FRONTAL BOUNDARY AND PRE-FRONTAL LOW LEVEL CONVERGENCE ON THE
NOSE OF THE 850-700 MB JET HELP FOCUS RAINFALL.  THE WPC QPF USED
A CONSENSUS OF THE 00-12Z ECMWF/12Z GFS/12Z UKMET.  12Z NAM MI
AMOUNTS SHOULD NOT BE HIGH AS FORWARD PROPAGATION IS FAVORED BY
THE VEERING WIND PROFILES WITH TIME.
CONVECTION MOVES DOWNSTREAM INTO NY/PA AND NEW ENGLAND WITH
ENHANCEMENTS WHERE UPSLOPE FLOW DEVELOPS IN WINDWARD TERRAIN.  THE
FRONT REACHES THE COAST OF NEW ENGLAND ON TUE AND BEYOND INTO THE
OFFSHORE WATERS.
POST FRONTAL COLD ADVECTION DEVELOPS BUT MOST CONDITIONS PERSIST
SFC-700 MB AND LOW LEVEL ASCENT SUPPORT MORE SHOWERS IN THE NY
ADIRONDACKS AND VT GREEN MOUNTAINS.

...CENTRAL TO SOUTHERN ROCKIES EAST TO CENTRAL TO SOUTHERN
PLAINS...

ONE AREA OF SHOWERS/STORMS DEVELOPS WITHIN 850-700 MB THETA-E
ADVECTION AND FRONTOGENESIS IN A NORTHWEST SOUTHEAST AXIS
EXTENDING FROM THE WY/SD BORDER ACROSS NE AND THEN NORTHERN MO ON
DAY 3.
THE TRICK HERE IS THE MODELS DIFFER ON TIMING AND WHERE ANY
CIRCULATION CENTERS MAY DEVELOP WITHIN THE FRONTAL ZONE.

ON DAY 2...A 700 MB WAVE CROSSES OUT OF UT ACROSS CO AND NORTHERN
NM. ENHANCED MOISTURE AND LIFT ALONG AND AHEAD OF THE WAVE TRIGGER
SHOWERS AND STORMS ACROSS THE UT WASATCH AND THE RANGES OF CO DOWN
INTO NORTHEAST NM AND THEN THE HIGH PLAINS INTO THE TX PANHANDLE.
ON DAY 3 THIS WAVE CONTINUES NORTHEAST WITH SHOWERS AND STORMS
HEADING INTO OK/KS/MO.  THE DIFFER ON TIMING AND PHASING OF THE
700-500 MB WAVE SO A BLEND OF THE 00-12Z ECMWF/12Z UKMET/12Z
GFS/12Z NAM QPF WAS USED.

...SOUTHEAST/FLORIDA...

THE MODELS SHOW A PERSISTENT LOW LEVEL CIRCULATION WITH ENHANCED
MOISTURE AS BANDS OF 2.25 INCHES OF PRECIPITABLE WATER PERSIST OF
WEST CENTRAL FL.  LOCAL AMOUNTS OF 4-7" REMAIN POSSIBLE ALONG THE
COAST OF THE WESTERN FL PENINSULA SO SLIGHT RISK AREAS WERE
INCLUDED ON THE EXCESSIVE RAINFALL GRAPHICS EACH DAY.
THE AMOUNTS BEGIN TO TAPER AS THE LOW LEVEL CIRCULATION WEAKENS ON
DAY 3 AND PRESSURES RISE AS A RIDGE BUILDS ACROSS THE STATE.  WEAK
LOW LEVEL FLOW LEADS TO BOTH SEA BREEZES PROPAGATING INLAND WITH
INTERIOR SHOWERS/STORMS TUE AFTERNOON RESULTING FROM SEA BREEZE
AND LAKE BREEZE COLLISIONS.

THE 09Z SREF MEAN/12Z UKMET LOOK OVERDONE WITH AMOUNTS ACROSS
GA/SC/NC. THE 00-12Z UKMET RUNS HAVE BEEN TRYING TO SPIN UP
CONVECTIVE LOWS OVER THE SOUTHEAST WHICH INDUCES HEAVY RAINFALL
ALONG THE SOUTHEAST COAST. A COMPROMISE OF THE 00Z-12Z GFS/ECMWF
WAS USED IN THIS REGION...WITH THE 12Z CANADIAN GLOBAL ALSO USED
IN THE FL PENINSULA DAY 3.

THE PRESENCE OF THE TROUGH...WHICH PROMOTES A CORRIDOR OF ENHANCED
WIND FIELDS AND REPLENISHMENT OF STEEPER MID LEVEL LAPSE
RATES...THERE IS CONCERN OVER HEFTY RAIN RATES. EVOLUTION OF
INDIVIDUAL CONVECTIVE CELLS AND CLUSTERS...HOWEVER...MAKES THE
EVENT A LITTLE LESS PRONE TO WIDESPREAD EXCESSIVE RAINFALL.
CONVECTION FORMING OVER THE PENINSULA DURING THE DAY WILL
PROPAGATE QUICKLY EAST ACROSS THE LAND...CAUGHT UP IN MODERATE
SOUTHWESTERLY FLOW...AND THE WESTERN RING OF OUTFLOWS WILL
PROPAGATE MORE SLOWLY INTO THE INFLOW...PLACING QPF MAXIMA
GENERALLY OFFSHORE. ANY OF THIS ACTIVITY COULD PRODUCE BRIEF VERY
HEAVY RAIN RATES AND URBAN FLOODING. POTENTIAL FOR LONGER LASTING
HEAVY RAIN APPEARS LIMITED TO THE COAST...AND ESPECIALLY THE WEST
COAST OF FLORIDA...WITH CONVECTION FEEDING OFF THE LARGER
RESERVOIR OF MODERATE CAPE OVER THE GULF WATERS. THE RISK OF
EXCESSIVE RAINS IS GREATEST ALONG THE COAST FROM THE NORTH SIDE OF
TAMPA BAY THROUGH CEDAR KEY TO SAINT MARKS. THIS IS WHERE THE
CIRCULATION EMBEDDED WITHIN THE TROUGH IS FORECAST TO SHOW SLIGHT
DEEPENING...WITH MORE PERSISTENT VERTICAL MOTION HELPING TO
SUSTAIN HEAVY RAIN IN SPITE OF OUTFLOWS...ESPECIALLY LATE SATURDAY
NIGHT INTO SUNDAY.

OTHER DIURNAL ACTIVITY PRODUCING LOCALLY HEAVY RAIN IS EXPECTED IN
SOUTHERN SC TO SOUTHERN GA EACH DAY WHERE THE COLD FRONT HAD
FAILED TO PUSH TO THE COAST. WPC QPF HAD THIS REGION HANDLED
WELL...AND MINIMAL CHANGES WERE MADE...INCORPORATING THE 12Z
WRF-ARW AND NMM.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

THE REGION FROM THE HIGH PLAINS OF KS/NE TOWARD THE MIDWEST AND UP
INTO THE GREAT LAKES IS FORECAST TO EXPERIENCE SCATTERED OR
WIDESPREAD PRECIPITATION THROUGH SUNDAY AFTERNOON. THE MESOSCALE
DETAILS ARE DIFFICULT TO PIN DOWN GIVEN SUBTLE DIFFERENCES IN
MOISTURE DEPTH AND STRENGTH OF ASCENT STRETCHED ACROSS A
BACKGROUND OF OTHERWISE FAVORABLE LAPSE RATES AND LARGE SCALE
LIFT. JUDGING BY OBSERVATIONS...THE AXIS FROM EASTERN NE INTO
SOUTHERN IA AND NORTHERN MO SHOULD BE ACTIVE LATE TODAY AND
OVERNIGHT...WITH ADVECTION ON THE 310 K ISENTROPIC SURFACE NEAR
THE ENTRANCE REGION OF A STANDING 250 MB JET STREAK. ANOTHER
ACTIVE AXIS SHOULD BE FROM THE EASTERN DAKOTAS ACROSS SOUTHERN MN
ALONG A DEVELOPING WARM FRONT...AS A SHORTWAVE SHARPENS WITHIN
NORTHWESTERLY FLOW. A SECONDARY...STRONGER COLD FRONT WILL ALSO
ENTER NORTHERN ND/MN OVERNIGHT...RESULTING IN A THIRD RELATIVE
MAXIMUM OF ACTIVITY. ALL OF THIS SPREADS DOWNSTREAM INTO THE GREAT
LAKES ON SUNDAY...WITH BROAD WARM ADVECTION AND HEIGHT FALLS
SUPPORTING WIDESPREAD COVERAGE OF CONVECTION...ALTHOUGH MARGINAL
MOISTURE QUALITY AND RAPID MOVEMENT WOULD ARGUE AGAINST ANYTHING
TOO HEAVY IN THE AREAL AVERAGE QPF. THE MODEL SIGNALS SHOW
SIMILARITIES...BUT HAVE A NUMBER OF TIMING AND PLACEMENT
DISPARITIES...NOT THE LEAST OF WHICH IS THE FACT THAT SOME OF THE
12Z HI-RES MODELS INDICATE NO PRECIPITATION OVER NORTHERN IOWA
WHILE SOME OF THE GLOBAL GUIDANCE IS MAXIMIZED THERE. WPC SPLIT
THE DIFFERENCE TO SOME RESPECT...AS THE 310 K UPGLIDE MAY
INTERCEPT MOISTURE AND RESULT IN A PRECIP AXIS FARTHER
SOUTHWEST...BUT DEEP ASCENT AND MOISTURE CONVERGENCE INTO NORTHERN
IOWA SHOULD SUPPORT AT LEAST SOME PRECIPITATION. WE USED A BLEND
OF THE 12Z NAM CONEST...WRF-NMM...AND UKMET TO UPDATE THE FORECAST.


...WESTERN U.S...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS SUGGEST LOCAL
AMOUNTS ABOVE 2 INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF
THE VALUES THAT THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD
THREAT SHOULD BE ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE
DOWNPOURS SETTING UP OVER PLACES THAT ARE MORE SUSCEPTIBLE. FOR
QPF...THE NAM HAD A GOOD HANDLE ON THE SHEAR AXIS OVER AZ/NV...AND
ITS QPF LOOKED GOOD. WE USED A BLEND OF 40 PERCENT CONTINUITY WITH
50 PERCENT NAM AND 10 PERCENT GFS FOR AREAS WEST OF THE
CONTINENTAL DIVIDE. FOR AREAS EAST INTO CO/NM WE USED A SIMILAR
BLEND...BUT PREFERRED THE NAM CONUS NEST WHICH PICKED OUT MORE
DETAIL OVER COLORADO.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
243 PM EDT SAT AUG 01 2015


PRELIM DAY 1 QPF DISCUSSION
VALID AUG 02/0000 UTC THRU AUG 03/0000 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...

...FLORIDA AND ADJACENT STATES...

IT IS A WET PATTERN ACROSS FLORIDA...WITH A BROAD MID LEVEL TROUGH
AND WIDE ZONE OF VERY RICH MOISTURE TO EITHER SIDE OF THE TROUGH
AXIS. PRECIPITABLE WATER VALUES ARE RUNNING BETWEEN 1.9 AND 2.25
INCHES ON AVERAGE. THE LOW LEVEL REFLECTION / FRONTAL BOUNDARY
RELATED TO THE UPPER TROUGH IS STRETCHED WEST TO EAST ACROSS THE
GULF...WITH WEAK LOW PRESSURE TAKING SHAPE IN THE EASTERN GULF
CLOSE TO THE COAST OF NORTHWEST FLORIDA. GIVEN THE MOISTURE AND
THE PRESENCE OF THE TROUGH...WHICH PROMOTES A CORRIDOR OF ENHANCED
WIND FIELDS AND REPLENISHMENT OF STEEPER MID LEVEL LAPSE
RATES...THERE IS CONCERN OVER HEFTY RAIN RATES. EVOLUTION OF
INDIVIDUAL CONVECTIVE CELLS AND CLUSTERS...HOWEVER...MAKES THE
EVENT A LITTLE LESS PRONE TO WIDESPREAD EXCESSIVE RAINFALL.
CONVECTION FORMING OVER THE PENINSULA DURING THE DAY WILL
PROPAGATE QUICKLY EAST ACROSS THE LAND...CAUGHT UP IN MODERATE
SOUTHWESTERLY FLOW...AND THE WESTERN RING OF OUTFLOWS WILL
PROPAGATE MORE SLOWLY INTO THE INFLOW...PLACING QPF MAXIMA
GENERALLY OFFSHORE. ANY OF THIS ACTIVITY COULD PRODUCE BRIEF VERY
HEAVY RAIN RATES AND URBAN FLOODING. POTENTIAL FOR LONGER LASTING
HEAVY RAIN APPEARS LIMITED TO THE COAST...AND ESPECIALLY THE WEST
COAST OF FLORIDA...WITH CONVECTION FEEDING OFF THE LARGER
RESERVOIR OF MODERATE CAPE OVER THE GULF WATERS. THE RISK OF
EXCESSIVE RAINS IS GREATEST ALONG THE COAST FROM THE NORTH SIDE OF
TAMPA BAY THROUGH CEDAR KEY TO SAINT MARKS. THIS IS WHERE THE
CIRCULATION EMBEDDED WITHIN THE TROUGH IS FORECAST TO SHOW SLIGHT
DEEPENING...WITH MORE PERSISTENT VERTICAL MOTION HELPING TO
SUSTAIN HEAVY RAIN IN SPITE OF OUTFLOWS...ESPECIALLY LATE SATURDAY
NIGHT INTO SUNDAY.

OTHER DIURNAL ACTIVITY PRODUCING LOCALLY HEAVY RAIN IS EXPECTED IN
SOUTHERN SC TO SOUTHERN GA EACH DAY WHERE THE COLD FRONT HAD
FAILED TO PUSH TO THE COAST. WPC QPF HAD THIS REGION HANDLED
WELL...AND MINIMAL CHANGES WERE MADE...INCORPORATING THE 12Z
WRF-ARW AND NMM.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

THE REGION FROM THE HIGH PLAINS OF KS/NE TOWARD THE MIDWEST AND UP
INTO THE GREAT LAKES IS FORECAST TO EXPERIENCE SCATTERED OR
WIDESPREAD PRECIPITATION THROUGH SUNDAY AFTERNOON. THE MESOSCALE
DETAILS ARE DIFFICULT TO PIN DOWN GIVEN SUBTLE DIFFERENCES IN
MOISTURE DEPTH AND STRENGTH OF ASCENT STRETCHED ACROSS A
BACKGROUND OF OTHERWISE FAVORABLE LAPSE RATES AND LARGE SCALE
LIFT. JUDGING BY OBSERVATIONS...THE AXIS FROM EASTERN NE INTO
SOUTHERN IA AND NORTHERN MO SHOULD BE ACTIVE LATE TODAY AND
OVERNIGHT...WITH ADVECTION ON THE 310 K ISENTROPIC SURFACE NEAR
THE ENTRANCE REGION OF A STANDING 250 MB JET STREAK. ANOTHER
ACTIVE AXIS SHOULD BE FROM THE EASTERN DAKOTAS ACROSS SOUTHERN MN
ALONG A DEVELOPING WARM FRONT...AS A SHORTWAVE SHARPENS WITHIN
NORTHWESTERLY FLOW. A SECONDARY...STRONGER COLD FRONT WILL ALSO
ENTER NORTHERN ND/MN OVERNIGHT...RESULTING IN A THIRD RELATIVE
MAXIMUM OF ACTIVITY. ALL OF THIS SPREADS DOWNSTREAM INTO THE GREAT
LAKES ON SUNDAY...WITH BROAD WARM ADVECTION AND HEIGHT FALLS
SUPPORTING WIDESPREAD COVERAGE OF CONVECTION...ALTHOUGH MARGINAL
MOISTURE QUALITY AND RAPID MOVEMENT WOULD ARGUE AGAINST ANYTHING
TOO HEAVY IN THE AREAL AVERAGE QPF. THE MODEL SIGNALS SHOW
SIMILARITIES...BUT HAVE A NUMBER OF TIMING AND PLACEMENT
DISPARITIES...NOT THE LEAST OF WHICH IS THE FACT THAT SOME OF THE
12Z HI-RES MODELS INDICATE NO PRECIPITATION OVER NORTHERN IOWA
WHILE SOME OF THE GLOBAL GUIDANCE IS MAXIMIZED THERE. WPC SPLIT
THE DIFFERENCE TO SOME RESPECT...AS THE 310 K UPGLIDE MAY
INTERCEPT MOISTURE AND RESULT IN A PRECIP AXIS FARTHER
SOUTHWEST...BUT DEEP ASCENT AND MOISTURE CONVERGENCE INTO NORTHERN
IOWA SHOULD SUPPORT AT LEAST SOME PRECIPITATION. WE USED A BLEND
OF THE 12Z NAM CONEST...WRF-NMM...AND UKMET TO UPDATE THE FORECAST.


...WESTERN U.S...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS SUGGEST LOCAL
AMOUNTS ABOVE 2 INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF
THE VALUES THAT THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD
THREAT SHOULD BE ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE
DOWNPOURS SETTING UP OVER PLACES THAT ARE MORE SUSCEPTIBLE. FOR
QPF...THE NAM HAD A GOOD HANDLE ON THE SHEAR AXIS OVER AZ/NV...AND
ITS QPF LOOKED GOOD. WE USED A BLEND OF 40 PERCENT CONTINUITY WITH
50 PERCENT NAM AND 10 PERCENT GFS FOR AREAS WEST OF THE
CONTINENTAL DIVIDE. FOR AREAS EAST INTO CO/NM WE USED A SIMILAR
BLEND...BUT PREFERRED THE NAM CONUS NEST WHICH PICKED OUT MORE
DETAIL OVER COLORADO.

EXCESSIVE RAINFALL DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1100 AM EDT SAT AUG 01 2015

...VALID 15Z SAT AUG 01 2015 - 12Z SUN AUG 02 2015...
...REFERENCE AWIPS GRAPHIC UNDER...DAY 1 EXCESSIVE RAINFALL...


SLIGHT RISK OF RAINFALL EXCEEDING FFG TO THE RIGHT OF A LINE FROM
10 S LEE 30 SE BOW 30 NNE PGD 10 N SRQ 30 WSW PIE 70 SE AAF
45 WSW AAF 25 N AAF 20 ESE TLH 30 E 40J 15 NNW OCF 10 S LEE.


..FL...

THE SLIGHT RISK AREA IN FLORIDA WAS EXPANDED SOMEWHAT...TO INCLUDE
AREAS FARTHER SOUTH INTO THE TAMPA BAY AREA AND OVER THROUGH THE
CENTRAL PART OF THE PENINSULA. THE EXPECTATION IS THAT VERY HIGH
RAIN RATES ARE THE MAIN CONCERN...RATHER THAN PARTICULARLY
EXCESSIVE RAIN TOTALS. THE MODEL TRENDS HAVE BEEN TOWARD LESSER
EVENT TOTALS...AS CONVECTION WILL BE PRONE TO FORMING ALONG THE
COAST AND RADIATING OUT...QUICKLY PROPAGATING EAST THROUGH THE
MIXED BOUNDARY LAYER OVER THE PENINSULA...AND PROPAGATING MORE
SLOWLY WEST INTO THE BETTER INFLOW. WHILE THE POSSIBLITY FOR
EXTREME RAIN TOTALS...MORE THAN 5 INCHES POSSIBLE THROUGH
SUNDAY...REMAINS IN TACT NEAR THE COAST...THE OVERALL EVENT SHOULD
BE CHARACTERIZED MORE BY UNUSUALLY HIGH SHORT TERM RAIN RATES
GIVEN SUCH ANOMALOUS PW VALUES EXCEEDING 2.25 INCHES AT TIMES.

...PREVIOUS FL DISCUSSION...

A SLOWING FRONTAL BOUNDARY SHOULD BECOME QUASI STATIONARY ACROSS
PORTIONS OF THE SOUTHEAST STATES INTO THE WESTERN FL PANHANDLE.
THE FRONT SERVES TO FOCUS LOW LEVEL CONVERGENCE AND
INSTABILITY...WHICH TAPS DEEP TROPICAL MOISTURE (WITH PRECIPITABLE
WATER VALUES OF 2.25+ INCHES) TO PRODUCE CONVECTIVE CLUSTERS NEAR
THE FRONT...STRETCHING FROM ACROSS SOUTHEAST GA ACROSS NORTHERN FL
AND A PORTION OF THE WESTERN FL PANHANDLE. THE MID LEVEL STEERING
CURRENT IS FAIRLY WEAK...SUPPORTING SLOW CELL MOVEMENT ALONG THE
FRONT OVER THE ABOVEMENTIONED LOCATIONS. THE BEST CONCENTRATION OF
CONVECTIVE CLUSTERS IS EXPECTED ACROSS THE EASTERN FL PANHANDLE
ACROSS PORTIONS OF THE WEST COAST OF THE PENINSULA. OVER THIS
AREA...1.50 TO 3.00 INCHES OF QPF WAS PLACED...WITH THE HIGHEST
AMOUNTS BETWEEN KCTY AND KBKV.

THERE IS REMARKABLE CONSISTENCY AMONG THE VARIOUS 00Z
REGIONAL/GLOBAL SOLUTIONS PLACING 3.00 TO 4.00 INCHES OF QPF IN
THE ABOVEMENTIONED LOCATIONS. SOME OF THE 00Z HIGH RESOLUTION
MODEL SOLUTIONS PLACED MAXIMUM NEAR 8 INCHES (INCLUDING THE 00Z
WRF ARW/NMMB AND 00Z REGIONAL GEM..WHICH WAS CLOSER TO 11 INCHES
OF QPF) IN THIS AREA...OR JUST OFFSHORE. THESE AMOUNTS COULD BE
PLAUSIBLE...GIVEN THE DEEP MOISTURE IN PLACE AND SLOW
CELL/CLUSTER MOVEMENT. HOWEVER...SINCE THERE IS SOME SPREAD AS TO
WHETHER THE HIGHEST QPF AMOUNTS OCCUR JUST OFFSHORE OR ON LAND
OVER NORTHWEST FL...A MORE CONSERVATIVE APPROACH WAS USED FOR THE
WPC QPF. IN ANY EVENT...THE POTENTIAL FOR HIGH RAINFALL RATES AND
SLOW CELL MOTIONS NECESSITATE A SLIGHT RISK AREA FOR PORTIONS OF
NORTH FL.


...SOUTHWEST/GREAT BASIN...

MOISTURE AND INSTABILITY WERE SOMEWHAT TYPICAL FOR THE MONSOON
SEASON PER REGIONAL 12Z SOUNDINGS. DRY LOW LEVEL AIR EXTENDED UP
THROUGH A FAIR DEPTH IN SOUNDINGS FROM AZ TO NV...WHICH WILL CUT
DOWN ON PRECIPITATION EFFICIENCY...ALTHOUGH ENHANCED MID AND HIGH
LEVEL MOISTURE WILL LEND 0.75 TO 1.25 INCH PRECIPITABLE WATER TO
THUNDERSTORMS FORMING ON THE HIGH TERRAIN. A SHEAR AXIS AT THE
WESTERN PERIPHERY OF THE MID LEVEL RIDGE EXTENDED ACROSS WESTERN
NV NEAR THE CA BORDER...DOWN INTO CENTRAL AZ. AN EMBEDDED
SHORTWAVE TROUGH WILL LIFT NORTHWARD TODAY OUT OF AZ TOWARD
SOUTHERN NV. LIFT ASSOCIATED WITH THE SHORT WAVE COULD ALLOW FOR
GREATER ORGANIZATION OF CONVECTION...AND GIVEN THE EXPECTED
MOISTURE PROFILES...ISOLATED HEAVY RAINFALL. THE MODEL QPF SIGNAL
IS THAT OF AN AVERAGE DAY IN THE WESTERN U.S...WITHOUT MUCH
SPECIFIC FOCUS. SOME HIGH RESOLUTION SOLUTIONS (SUCH AS THE 00Z
WRF ARW AND 00Z NAM CONEST) SUGGEST LOCAL AMOUNTS ABOVE 2
INCHES...BUT AGAIN THIS IS TOWARD THE LOWER END OF THE VALUES THAT
THOSE MODELS TYPICALLY GENERATE. THE FLASH FLOOD THREAT SHOULD BE
ON SMALL SCALES AND DEPENDENT ON BRIEFLY INTENSE DOWNPOURS SETTING
UP OVER PLACES THAT ARE MORE SUSCEPTIBLE.


...SOUTHERN HIGH PLAINS...

EARLY MORNING CONVECTION ACROSS NORTH TX SHOULD PRODUCE AN
MCV...WHICH CROSSES NORTH TX INTO SOUTHWEST OK THIS MORNING INTO
THE AFTERNOON. THE MCV SHOULD PROVIDE SUFFICIENT SUPPORT FOR
ADDITIONAL CONVECTION IN ITS PATH INTO THE AFTERNOON HOURS.
ADDITIONAL CONVECTION IS EXPECTED TO DEVELOP ACROSS NORTHEAST NM
THIS AFTERNOON AND EVENING...WHICH SHOULD FOLLOW THE SAME PATH AS
THE CONVECTION THIS MORNING...AS THE MID LEVEL RIDGE REMAINS IN
PLACE. AS THE LOW LEVEL FLOW INCREASES AGAIN ACROSS NORTH
TX/WESTERN OK/WESTERN KS AFTER 02/00Z...ADDITIONAL CONVECTION
COULD DEVELOP ON THE NOSE OF A LOW LEVEL JET NEAR 02/06Z ACROSS
NORTH TX...WHICH MOVES INTO SOUTHWEST OK. WHILE THERE IS SOME
MODEL COMMONALITY AMONG 00Z MODEL SOLUTIONS HERE...IT IT NOT CLEAR
IF A FULL BLOWN MCS DEVELOPS IN THE PRESENCE OF THE LOW LEVEL
JET...AS UPPER SUPPORT WILL BE LACKING...AND INFLOW OVERNIGHT WILL
COME FROM DRIER SOURCE REGIONS TO THE SOUTH OF THE SEMI-PERMANENT
WEAK FRONTAL ZONE.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
449 AM EDT SAT AUG 01 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 01/1200 UTC THRU AUG 04/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


...SOUTHERN PLAINS...

DEEP MOISTURE AND INSTABILITY FROM THE MONSOONAL FLOW OVER THE
SOUTHWEST IS TRANSPORTED INTO THE SOUTHERN PLAINS ON A
STRENGTHENING LOW LEVEL SOUTHERLY FLOW. THE MOISTURE AND
INSTABILITY SHOULD FEED DEVELOPING CONVECTIVE COMPLEXES ALONG AN
ELEVATED BOUNDARY EXTENDING ACROSS NORTH TX AND PORTIONS OF
SOUTHWEST OK...WHICH MAY PRODUCE HEAVY TO EXCESSIVE RAINFALL. FOR
THE MOST PART...THERE WAS GOOD OVERALL AGREEMENT WITH THE SYNOPTIC
SETUP. HOWEVER...THERE WAS SOME MODEL SPREAD CONCERNING THE
PLACEMENT OF THE MAXIMUM QPF (LATITUDINAL DIFFERENCES ACROSS NORTH
TX BEING THE BIGGEST FORECAST CONCERN). A BLEND OF THE 00Z
NAM/GFS/ECMWF WAS USED TO PRODUCE THE LARGE SCALE WPC QPF...AND
THE 00Z WRF ARW/00Z REGIONAL GEM WERE USED TO BETTER DEFINE THE
PLACEMENT OF THE MAXIMUM QPF.

EARLY MORNING CONVECTION ACROSS NORTH TX SHOULD PRODUCE AN
MCV...WHICH CROSSES NORTH TX INTO SOUTHWEST OK THIS MORNING INTO
THE AFTERNOON. THE MCV SHOULD PROVIDE SUFFICIENT SUPPORT FOR
ADDITIONAL CONVECTION IN ITS PATH INTO THE AFTERNOON HOURS.
CONVECTION IS EXPECTED TO DEVELOP ACROSS NORTHEAST NM THIS
AFTERNOON AND EVENING...WHICH SHOULD FOLLOW THE SAME PATH AS THE
CONVECTION THIS MORNING...AS THE MID LEVEL RIDGE REMAINS IN PLACE.
AS THE LOW LEVEL FLOW INCREASES AGAIN ACROSS NORTH TX/WESTERN
OK/WESTERN KS AFTER 02/00Z...ADDITIONAL CONVECTION COULD DEVELOP
ON THE NOSE OF A LOW LEVEL JET NEAR 02/06Z ACROSS NORTH TX...WHICH
MOVES INTO SOUTHWEST OK. WHILE THERE IS SOME MODEL COMMONALITY
AMONG 00Z MODEL SOLUTIONS HERE...IT IT NOT CLEAR IF A FULL BLOWN
MCS DEVELOPS IN THE PRESENCE OP THE LOW LEVEL JET. FOR NOW...A
MORE CONSERVATIVE APPROACH WAS USED FOR QPF. IT SHOULD BE NOTED
THAT SOME OF THE HIGH RESOLUTION GUIDANCE (ESPECIALLY THE 00Z
REGIONAL GEM...00Z WRF ARW AND 00Z NAM CONEST) PRODUCE AMOUNTS IN
EXCESS OF 3 INCHES. THE HIGH MOISTURE CONTENT OF THE AIRMASS MAKES
THAT PLAUSIBLE...SO A SLIGHT RISK WAS RETAINED FOR THIS AREA.


...SOUTHWEST/GREAT BASIN/CA...

DEEP MOISTURE AND INSTABILITY IN THE MONSOONAL FLOW ACROSS THE
SOUTHWEST AND GREAT BASIN CONTINUES DURING DAY 1...WHICH FEEDS
DEVELOPING CONVECTION ACROSS THE REGION. THERE IS A MULTI MODEL
SIGNAL THAT A SHORT WAVE TRACKING OUT OF NORTHWEST MEXICO CROSSES
AZ ON ITS WAY INTO SOUTHERN AND WESTERN NV. THE LIFT ASSOCIATED
WITH THE SHORT WAVE COULD ALLOW MORE ORGANIZATION OF
CONVECTION...AND GIVEN THE EXPECTED MOISTURE PROFILES...LOCALLY
HEAVY TO POSSIBLY EXCESSIVE RAINFALL IS POSSIBLE. THERE WAS SOME
MODEL SPREAD CONCERNING THE EXTENT OF THE CONVECTION...ESPECIALLY
ACROSS NV/NORTHERN CA. THE 00Z NAM/GFS WERE MORE GENEROUS WITH
COVERAGE...AS WELL AS HIGHER QPF AMOUNTS. THE 00Z ECMWF WAS LESS
GENEROUS WITH BOTH...SO FOR NOW A BLEND OF THE 00Z NAM/GFS/ECMWF
WAS USED TO CREATE THE LARGER SCALE WPC QPF. THE 00Z WRF ARW/NMMB
SOLUTIONS WERE EMPLOYED TO BETTER DEFINE QPF AMOUNTS IN THE HIGHER
TERRAIN OF AZ AND NV.

HIGH MOISTURE CONTENT AIR (WITH PRECIPITABLE WATER VALUES TOPPING
OUT NEAR 1.75 INCHES ACROSS PORTIONS OF AZ) AND MARGINAL
INSTABILITY SHOULD AGAIN COMBINE TO PRODUCE AT LEAST SCATTERED
CONVECTION NM/AZ INTO PORTIONS OF NORTHERN CA AND MUCH OF NV.
INITIALLY...THE CONVECTION SHOULD BE TIED TO THE TERRAIN...WHERE
LOCAL UPSLOPE ACROSS PORTIONS OF
NM/SOUTHERN CO SHOULD HELP FOCUS INSTABILITY AND MOISTURE. ACROSS
THE TERRAIN OF NM AND AZ...AREAS OF 0.25 TO 0.50 INCHES OF QPF ARE
EXPECTED. FOR THIS MOST PART...THESE VALUES ARE BELOW THE ONE AND
THREE HOUR FLASH FLOOD GUIDANCE NUMBERS.

THERE IS A MULTI MODEL CONSENSUS THAT A DECENT SHORT WAVE TRACKS
OUT OF NORTHWEST MEXICO ACROSS AZ INTO SOUTHERN AND CENTRAL
NV...MAINLY AFTER 01/18Z. THE SHORT WAVE SHOULD PRODUCE ENOUGH
LIFT TO SUPPORT MORE ORGANIZED CONVECTION ACROSS NORTHWEST AZ INTO
PORTIONS OF SOUTHERN AND CENTRAL NV AND NEARBY EAST CENTRAL CA.
WHILE THE BASIN AVERAGE QPF VALUES SHOULD BE LESS THAN 0.50
INCHES...THE HIGH MOISTURE CONTENT AIR (WITH PRECIPITABLE WATER
VALUES BETWEEN THREE AND FOUR STANDARD DEVIATIONS ABOVE THE MEAN)
SUGGEST THAT LOCAL HIGHER AMOUNTS ARE POSSIBLE...AND SOME HIGH
RESOLUTION SOLUTIONS (SUCH AS THE 00Z WRF ARW AND 00Z NAM CONEST)
SUGGEST LOCAL 2-3 INCH AMOUNTS. SINCE IT IS NOT CLEAR WHERE THESE
AMOUNTS WILL OCCUR...A SEE TEXT WAS ISSUED FOR MUCH OF WESTERN
AZ/SOUTHERN AND CENTRAL NV. SHOULD THE FOCUS FOR CONVECTION BECOME
CLEARER LATER TODAY...THIS COULD BE UPGRADED TO A SLIGHT RISK.


...SOUTHEAST/GULF COAST...

A WEAKENING FRONTAL BOUNDARY PROVIDES LOW LEVEL CONVERGENCE AND A
FOCUS FOR DEVELOPING CONVECTION ACROSS THE SOUTHEAST AND FL DURING
DAY 1. THE ABUNDANCE OF MOISTURE IN THE COLUMN...AS WELL AS SLOW
CELL MOTION DUE TO A WEAK STEERING FLOW...SUGGESTS THAT CONVECTION
THAT DEVELOPS WILL PRODUCE HEAVY TO EXCESSIVE RAINFALL OVER
PORTIONS OF NORTHWEST FL. THERE WAS GENERALLY GOOD MODEL AGREEMENT
CONCERNING THE OVERALL SYNOPTIC SETUP. HOWEVER...THERE WERE
PLACEMENT DIFFERENCES WITH RESPECT TO THE MAXIMUM QPF (OVER LAND
AS OPPOSED TO JUST OFFSHORE). THE PLACEMENT DIFFERENCES WILL
RESULT IN A LOWER THAN AVERAGE CONFIDENCE FORECAST.

A SLOWING FRONTAL BOUNDARY SHOULD BECOME QUASI STATIONARY ACROSS
PORTIONS OF THE SOUTHEAST STATES INTO THE WESTERN FL PANHANDLE.
THE FRONT SERVES TO FOCUS LOW LEVEL CONVERGENCE AND
INSTABILITY...AND TAPS DEEP TROPICAL MOISTURE (WITH PRECIPITABLE
WATER VALUES OF 2.25+ INCHES) TO PRODUCE CONVECTIVE CLUSTERS NEAR
THE FRONT...STRETCHING FROM ACROSS SOUTHEAST GA ACROSS NORTHERN FL
AND A PORTION OF THE WESTERN FL PANHANDLE. THE MID LEVEL STEERING
CURRENT IS FAIRLY WEAK...SUPPORTING SLOW CELL MOVEMENT ALONG THE
FRONT OVER THE ABOVEMENTIONED LOCATIONS. THE BEST CONCENTRATION OF
CONVECTIVE CLUSTERS IS EXPECTED ACROSS THE EASTERN FL PANHANDLE
ACROSS PORTIONS OF THE WEST COAST OF THE PENINSULA. OVER THIS
AREA...1.50 TO 3.00 INCHES OF QPF WAS PLACED...WITH THE HIGHEST
AMOUNTS BETWEEN KCTY AND KBKV.

THERE IS REMARKABLE CONSISTENCY AMONG THE VARIOUS 00Z
REGIONAL/GLOBAL SOLUTIONS PLACING 3.00 TO 4.00 INCHES OF QPF IN
THE ABOVEMENTIONED LOCATIONS. SOME OF THE 00Z HIGH RESOLUTION
MODEL SOLUTIONS PLACED MAXIMUM NEAR 8 INCHES (INCLUDING THE 00Z
WRF ARW/NMMB AND 00Z REGIONAL GEM..WHICH WAS CLOSER TO 11 INCHES
OF QPF) IN THIS AREA...OR JUST OFFSHORE. THESE AMOUNTS ARE
PLAUSIBLE...GIVEN THE DEEP MOISTURE IN PLACE AND SLOW CELL/CLUSTER
MOVEMENT. HOWEVER...SINCE THERE IS SOME SPREAD AS TO WHETHER THE
HIGHEST QPF AMOUNTS OCCUR JUST OFFSHORE OR ON LAND OVER NORTHWEST
FL...A MORE CONSERVATIVE APPROACH WAS USED FOR THE WPC QPF. IN ANY
EVENT...THE POTENTIAL FOR HIGH RAINFALL RATES AND SLOW CELL
MOTIONS NECESSITATE A SLIGHT RISK AREA FOR PORTIONS OF NORTHWEST
FL.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

SHORT WAVES IN THE MID LEVEL FLOW PUSH A COLD FRONT ACROSS THE
NORTHERN PLAINS INTO THE GREAT LAKES...CENTRAL PLAINS AND MIDWEST
DURING DAY 1. STRONG INSTABILITY AND SUFFICIENTLY DEEP MOISTURE
SHOULD RESULT IN ORGANIZED CONVECTION ALONG THE FRONT...WHICH
COULD PRODUCE LOCALLY HEAVY RAINFALL. FOR THE MOST PART...THERE
WAS DECENT MODEL AGREEMENT WITH THE MASS FIELDS OVER THE
REGION...SO THE WPC QPF WAS BASED ON A BLEND OF THE 00Z
NAM/GFS/ECMWF. THE QPF WAS AUGMENTED BY THE 00Z WRF ARW/NMMB AS
NEEDED TO BETTER DEFINE WHERE THE BEST QPF AMOUNTS WERE PLACED.

A STRONG SHORT WAVE TRACKING FROM SD INTO IA SHOULD PUSH ALONG A
SURFACE FRONT ACROSS THE NORTHERN PLAINS INTO THE GREAT LAKES AND
MIDWEST. AHEAD OF THE FRONT...MOISTURE SIPHONED FROM THE SOUTHERN
PLAINS ON A LOW LEVEL SOUTHWEST FLOW FEEDS CONVECTION DEVELOPING
IN THE PRESENCE OF STRONG INSTABILITY ACROSS NE/IA. THIS SHOULD
RESULT IN CLUSTERS OR LINES OF CONVECTION DEVELOPING AHEAD OF THE
FRONT IN THE PRESENCE OF DEEP MOISTURE (WITH PRECIPITABLE WATER
VALUES TOPPING 1.50 INCHES). MODEL SOUNDINGS SHOWED DRY MID LEVELS
AT THE TIME OF CONVECTION INITIATION...WHICH SUPPORTS LESS OF A
HEAVY RAIN THREAT. HOWEVER...THE COLUMN MOISTENS WITH TIME...AND
LOCALLY HEAVY RAINFALL BECOMES POSSIBLE AFTER 02/00Z ACROSS
PORTIONS OF SOUTHEAST NE INTO SOUTHWEST IA. ALONG THIS
TRACK...0.50 TO 0.75 INCHES OF QPF ARE EXPECTED.

IT SHOULD BE NOTED THAT BOTH THE 00Z NAM/GFS HAS MAXIMUM QPF
AMOUNTS OVER 2.00 INCHES ALONG THIS AXIS...THOUGH NOT IN THE SAME
LOCATION. THE HIGHER MOISTURE VALUES IN THE COLUMN COULD SUPPORT
LOCALLY HIGHER AMOUNTS...BUT THE CONVECTION SHOULD KEEPING MOVING
DUE TO STRONG MID LEVEL WINDS. WHILE LOCALLY HEAVY RAINFALL IS
POSSIBLE...ORGANIZED FLASH FLOODING IS NOT EXPECTED.


...NORTHEAST...

A SHORT WAVE IN THE FAST MID LEVEL FLOW TAPS INSTABILITY AND
SUFFICIENT MOISTURE FOR LOW TOPPED CONVECTION...MAINLY ACROSS NEW
ENGLAND DURING DAY 1. THERE WAS GENERALLY GOOD MODEL AGREEMENT ON
THE SEQUENCE OF EVENTS...THOUGH THERE WAS SOME SPREAD CONCERNING
HOW MUCH MOISTURE (AND ULTIMATELY INSTABILITY) WILL BE AVAILABLE
FOR QPF WITH DEVELOPING CONVECTION. THE 00Z ECMWF APPEARED TO BE
PRODUCING THE MOST INSTABILITY ACROSS NORTHERN NEW ENGLAND AHEAD
OF THE SHORT WAVE...WHICH MAY BE TOO AGGRESSIVE GIVEN THE MOISTURE
AND INSTABILITY PROFILES. BECAUSE OF THIS...THE WPC QPF WAS BASED
PRIMARILY ON A BLEND OF THE 00Z NAM/GFS.

A SHORT WAVE CROSSING ONTARIO/QUEBEC EARLY DURING DAY 1 TRACKS
ACROSS NORTHERN NEW ENGLAND AFTER 01/18Z. AHEAD OF THE SHORT WAVE
(AND A WEAK SURFACE REFLECTION)...THE LOW LEVEL FLOW BACKS ENOUGH
TO TAP PRECIPITABLE WATER VALUES NEAR 1.00 INCHES...WHICH IS
FUNNELED PRIMARILY INTO NORTHERN NEW ENGLAND. MODEL SOUNDINGS
SUGGESTED INSTABILITY MAY BE THE LIMITING FACTOR...AS THE SHEAR
PROFILE LOOKS FAVORABLE FOR SOME ORGANIZATION. THE BEST CONVECTIVE
ACTIVITY SHOULD CROSS NORTHERN NEW ENGLAND BEFORE 02/00Z. GIVEN
THE MID LEVEL FLOW...QPF AMOUNTS SHOULD BE LIMITED TO 0.25 INCHES
ACROSS NORTHERN VT/NORTHERN NH AND NORTHERN AND WESTERN ME.



DAYS 2/3...

THE WEST
~~~~~~~~
THE GUIDANCE HAS COME INTO MUCH BETTER AGREEMENT IN THIS REGION.
COMPROMISED BETWEEN THE 00Z WPC QPF/12Z AND 00Z ECMWF/00Z GFS/OLD
00Z GEFS-BASED REFORECAST PATTERN WISE.  ENERGY MOVING THROUGH THE
GREAT BASIN/NV EARLY ON COULD LEAD TO LOCALIZED PROBLEMS FROM AN
EXCESSIVE RAINFALL PERSPECTIVE AS 700 HPA INFLOW OF 15-25 KTS IS
PROGGED WHICH COULD ORGANIZE CONVECTION -- IT SHOULD NOT BE PULSE.
 FOR THE TIME BEING, HAVE NOT INCLUDED AN EXCESSIVE RAINFALL AREA.
 THIS WILL NEED TO BE EVALUATED BY LATER SHIFTS.


GREAT LAKES/MIDWEST
~~~~~~~~~~~~~~~~~~~
A VARIETY OF CONVECTIVE SYSTEMS ARE POSSIBLE IN THIS REGION AS A
FRONTAL BOUNDARY AND RESULTANT OUTFLOW BOUNDARIES FROM EARLIER
CONVECTION HELP FOCUS RAINFALL.  THE 06Z/12Z WPC QPF IS CLOSEST TO
A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z WPC QPF ACROSS IL/MI --
STILL BELIEVE MI AMOUNTS SHOULD NOT BE EXTREME AS COMPLEXES
UPSTREAM SHOULD AT LEAST PARTIALLY INTERCEPT THE AVAILABLE
MOISTURE/INSTABILITY BUT DID NUDGE AMOUNTS SLIGHTLY UPWARDS.
TRENDS IN THE NAM OVER ITS PAST DAY OF RUNS HAVE DECREASED BY
ONE-THIRD ACROSS MI.  ACROSS THE MIDWEST (NE/IA) MONDAY, LIKED THE
PRECIPITATION PATTERN SHOWN BY THE 00Z GFS/00Z UKMET/00Z ECMWF
(DESPITE POSSIBLE MASS FIELD ISSUES WITH THE STRENGTH OF A 700 HPA
LOW MOVING INTO THE REGION IN THE 00Z GFS) AS CONVECTION SHOULD
PROPAGATE EAST-SOUTHEAST TO SOUTHEAST AT THE EDGE OF THE CAP.
INCLUDED A SLIGHT RISK OF EXCESSIVE RAINFALL IN THIS AREA DUE TO
THE RELATIVELY LOW FLASH FLOOD GUIDANCE CAUSED BY RECENT RAINS.


NORTHERN TX/OK/KS/CENTRAL HIGH PLAINS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
FOLLOWED THE THOUGHTS OF THE MODEL DIAGNOSTICS DISCUSSION AND
STAYED AWAY FROM THE MUCH WETTER 00Z GFS NEAR THE WY/NE/CO BORDER
JUNCTION ON MONDAY.  OTHERWISE, USE OF THE 18Z GFS MASS FIELDS AND
THE 31/00Z GEFS-BASED REFORECAST LED TO A SOLUTION THAT RESEMBLES
THE 00Z NAM/00Z ECMWF ON SUNDAY ACROSS NORTHERN TX/WESTERN OK.
INCLUDED A SLIGHT RISK OF EXCESSIVE RAINFALL IN THIS REGION AS
SOILS HAVE SATURATED AND COULD FURTHER SATURATE IN THE MEANTIME.
THE CONVECTION WILL LIKELY HAVE SOME CAP ISSUES AND REMAIN FORWARD
PROPAGATING INTO/THROUGH PORTIONS OF OK.


NORTHEAST
~~~~~~~~~
USED A COMPROMISE OF THE 00Z GFS/00Z ECMWF IN THIS REGION TO COME
UP WITH THE AMOUNTS EXPECTED, WHICH SLOWED DOWN PROGRESSION FROM
00Z AND 06Z WPC QPF CONTINUITY.  ON MONDAY, STRONG LOW-LEVEL
INFLOW (PER THE 00Z GFS) AND SUFFICIENT INSTABILITY (PER THE 21Z
SREF MEAN) ALONG WITH THE LOW FLASH FLOOD GUIDANCE VALUES ACROSS
NORTHERN NEW ENGLAND COULD LEAD TO FLASH FLOODING, SO INCLUDED A
SLIGHT RISK FOR DAY 3 IN THE EXCESSIVE RAINFALL PRODUCT.


SOUTHEAST/FLORIDA
~~~~~~~~~~~~~~~~~
A COMPROMISE OF THE 00Z GFS/00Z ECMWF LOOKED REASONABLE IN THIS
REGION.  VARIOUS MODEL RUNS OVER THE PAST DAY OR SO HAVE BEEN
TRYING TO SPIN UP CONVECTIVE LOWS OVER THE SOUTHEAST WHICH DRAGS
HEAVY RAINFALL INLAND OF THE COAST OF THE LOWER EASTERN SEABOARD.
THE 00Z UKMET/00Z CANADIAN TRENDED AWAY FROM THIS SCENARIO.  LOCAL
AMOUNTS OF 4-7" REMAIN POSSIBLE EACH DAY ALONG THE COAST OF THE
NORTHWESTERN FL PENINSULA AND THE EASTERN PANHANDLE MAINLY DURING
THE MORNING HOURS (06Z-15Z), SO SLIGHT RISK AREAS WERE INCLUDED ON
THE EXCESSIVE RAINFALL GRAPHICS EACH DAY.  THE AVAILABLE MOISTURE
SUPPORTS HOURLY RAIN RATES IN THE 2.5-3" AN HOUR RANGE, WHICH
SHORT SEGMENTS OF ORGANIZED CONVECTION COULD ACCOMPLISH.  LIKE
YESTERDAY, THE 21Z SREF MEAN LOOKS OVERDONE WITH AMOUNTS INLAND
ACROSS SC/NC, SO BELIEVE THE PROBABILISTIC QPF IS ALSO OVERDONE IN
THIS REGION.

QUANTITATIVE PRECIPITATION FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
449 AM EDT SAT AUG 01 2015


FINAL DAY 1...DAY 2 AND DAY 3 QPF DISCUSSION
VALID AUG 01/1200 UTC THRU AUG 04/1200 UTC
REFERENCE AWIPS GRAPHICS UNDER...PRECIP ACCUM - 24HR


DAY 1...


...SOUTHERN PLAINS...

DEEP MOISTURE AND INSTABILITY FROM THE MONSOONAL FLOW OVER THE
SOUTHWEST IS TRANSPORTED INTO THE SOUTHERN PLAINS ON A
STRENGTHENING LOW LEVEL SOUTHERLY FLOW. THE MOISTURE AND
INSTABILITY SHOULD FEED DEVELOPING CONVECTIVE COMPLEXES ALONG AN
ELEVATED BOUNDARY EXTENDING ACROSS NORTH TX AND PORTIONS OF
SOUTHWEST OK...WHICH MAY PRODUCE HEAVY TO EXCESSIVE RAINFALL. FOR
THE MOST PART...THERE WAS GOOD OVERALL AGREEMENT WITH THE SYNOPTIC
SETUP. HOWEVER...THERE WAS SOME MODEL SPREAD CONCERNING THE
PLACEMENT OF THE MAXIMUM QPF (LATITUDINAL DIFFERENCES ACROSS NORTH
TX BEING THE BIGGEST FORECAST CONCERN). A BLEND OF THE 00Z
NAM/GFS/ECMWF WAS USED TO PRODUCE THE LARGE SCALE WPC QPF...AND
THE 00Z WRF ARW/00Z REGIONAL GEM WERE USED TO BETTER DEFINE THE
PLACEMENT OF THE MAXIMUM QPF.

EARLY MORNING CONVECTION ACROSS NORTH TX SHOULD PRODUCE AN
MCV...WHICH CROSSES NORTH TX INTO SOUTHWEST OK THIS MORNING INTO
THE AFTERNOON. THE MCV SHOULD PROVIDE SUFFICIENT SUPPORT FOR
ADDITIONAL CONVECTION IN ITS PATH INTO THE AFTERNOON HOURS.
CONVECTION IS EXPECTED TO DEVELOP ACROSS NORTHEAST NM THIS
AFTERNOON AND EVENING...WHICH SHOULD FOLLOW THE SAME PATH AS THE
CONVECTION THIS MORNING...AS THE MID LEVEL RIDGE REMAINS IN PLACE.
AS THE LOW LEVEL FLOW INCREASES AGAIN ACROSS NORTH TX/WESTERN
OK/WESTERN KS AFTER 02/00Z...ADDITIONAL CONVECTION COULD DEVELOP
ON THE NOSE OF A LOW LEVEL JET NEAR 02/06Z ACROSS NORTH TX...WHICH
MOVES INTO SOUTHWEST OK. WHILE THERE IS SOME MODEL COMMONALITY
AMONG 00Z MODEL SOLUTIONS HERE...IT IT NOT CLEAR IF A FULL BLOWN
MCS DEVELOPS IN THE PRESENCE OP THE LOW LEVEL JET. FOR NOW...A
MORE CONSERVATIVE APPROACH WAS USED FOR QPF. IT SHOULD BE NOTED
THAT SOME OF THE HIGH RESOLUTION GUIDANCE (ESPECIALLY THE 00Z
REGIONAL GEM...00Z WRF ARW AND 00Z NAM CONEST) PRODUCE AMOUNTS IN
EXCESS OF 3 INCHES. THE HIGH MOISTURE CONTENT OF THE AIRMASS MAKES
THAT PLAUSIBLE...SO A SLIGHT RISK WAS RETAINED FOR THIS AREA.


...SOUTHWEST/GREAT BASIN/CA...

DEEP MOISTURE AND INSTABILITY IN THE MONSOONAL FLOW ACROSS THE
SOUTHWEST AND GREAT BASIN CONTINUES DURING DAY 1...WHICH FEEDS
DEVELOPING CONVECTION ACROSS THE REGION. THERE IS A MULTI MODEL
SIGNAL THAT A SHORT WAVE TRACKING OUT OF NORTHWEST MEXICO CROSSES
AZ ON ITS WAY INTO SOUTHERN AND WESTERN NV. THE LIFT ASSOCIATED
WITH THE SHORT WAVE COULD ALLOW MORE ORGANIZATION OF
CONVECTION...AND GIVEN THE EXPECTED MOISTURE PROFILES...LOCALLY
HEAVY TO POSSIBLY EXCESSIVE RAINFALL IS POSSIBLE. THERE WAS SOME
MODEL SPREAD CONCERNING THE EXTENT OF THE CONVECTION...ESPECIALLY
ACROSS NV/NORTHERN CA. THE 00Z NAM/GFS WERE MORE GENEROUS WITH
COVERAGE...AS WELL AS HIGHER QPF AMOUNTS. THE 00Z ECMWF WAS LESS
GENEROUS WITH BOTH...SO FOR NOW A BLEND OF THE 00Z NAM/GFS/ECMWF
WAS USED TO CREATE THE LARGER SCALE WPC QPF. THE 00Z WRF ARW/NMMB
SOLUTIONS WERE EMPLOYED TO BETTER DEFINE QPF AMOUNTS IN THE HIGHER
TERRAIN OF AZ AND NV.

HIGH MOISTURE CONTENT AIR (WITH PRECIPITABLE WATER VALUES TOPPING
OUT NEAR 1.75 INCHES ACROSS PORTIONS OF AZ) AND MARGINAL
INSTABILITY SHOULD AGAIN COMBINE TO PRODUCE AT LEAST SCATTERED
CONVECTION NM/AZ INTO PORTIONS OF NORTHERN CA AND MUCH OF NV.
INITIALLY...THE CONVECTION SHOULD BE TIED TO THE TERRAIN...WHERE
LOCAL UPSLOPE ACROSS PORTIONS OF
NM/SOUTHERN CO SHOULD HELP FOCUS INSTABILITY AND MOISTURE. ACROSS
THE TERRAIN OF NM AND AZ...AREAS OF 0.25 TO 0.50 INCHES OF QPF ARE
EXPECTED. FOR THIS MOST PART...THESE VALUES ARE BELOW THE ONE AND
THREE HOUR FLASH FLOOD GUIDANCE NUMBERS.

THERE IS A MULTI MODEL CONSENSUS THAT A DECENT SHORT WAVE TRACKS
OUT OF NORTHWEST MEXICO ACROSS AZ INTO SOUTHERN AND CENTRAL
NV...MAINLY AFTER 01/18Z. THE SHORT WAVE SHOULD PRODUCE ENOUGH
LIFT TO SUPPORT MORE ORGANIZED CONVECTION ACROSS NORTHWEST AZ INTO
PORTIONS OF SOUTHERN AND CENTRAL NV AND NEARBY EAST CENTRAL CA.
WHILE THE BASIN AVERAGE QPF VALUES SHOULD BE LESS THAN 0.50
INCHES...THE HIGH MOISTURE CONTENT AIR (WITH PRECIPITABLE WATER
VALUES BETWEEN THREE AND FOUR STANDARD DEVIATIONS ABOVE THE MEAN)
SUGGEST THAT LOCAL HIGHER AMOUNTS ARE POSSIBLE...AND SOME HIGH
RESOLUTION SOLUTIONS (SUCH AS THE 00Z WRF ARW AND 00Z NAM CONEST)
SUGGEST LOCAL 2-3 INCH AMOUNTS. SINCE IT IS NOT CLEAR WHERE THESE
AMOUNTS WILL OCCUR...A SEE TEXT WAS ISSUED FOR MUCH OF WESTERN
AZ/SOUTHERN AND CENTRAL NV. SHOULD THE FOCUS FOR CONVECTION BECOME
CLEARER LATER TODAY...THIS COULD BE UPGRADED TO A SLIGHT RISK.


...SOUTHEAST/GULF COAST...

A WEAKENING FRONTAL BOUNDARY PROVIDES LOW LEVEL CONVERGENCE AND A
FOCUS FOR DEVELOPING CONVECTION ACROSS THE SOUTHEAST AND FL DURING
DAY 1. THE ABUNDANCE OF MOISTURE IN THE COLUMN...AS WELL AS SLOW
CELL MOTION DUE TO A WEAK STEERING FLOW...SUGGESTS THAT CONVECTION
THAT DEVELOPS WILL PRODUCE HEAVY TO EXCESSIVE RAINFALL OVER
PORTIONS OF NORTHWEST FL. THERE WAS GENERALLY GOOD MODEL AGREEMENT
CONCERNING THE OVERALL SYNOPTIC SETUP. HOWEVER...THERE WERE
PLACEMENT DIFFERENCES WITH RESPECT TO THE MAXIMUM QPF (OVER LAND
AS OPPOSED TO JUST OFFSHORE). THE PLACEMENT DIFFERENCES WILL
RESULT IN A LOWER THAN AVERAGE CONFIDENCE FORECAST.

A SLOWING FRONTAL BOUNDARY SHOULD BECOME QUASI STATIONARY ACROSS
PORTIONS OF THE SOUTHEAST STATES INTO THE WESTERN FL PANHANDLE.
THE FRONT SERVES TO FOCUS LOW LEVEL CONVERGENCE AND
INSTABILITY...AND TAPS DEEP TROPICAL MOISTURE (WITH PRECIPITABLE
WATER VALUES OF 2.25+ INCHES) TO PRODUCE CONVECTIVE CLUSTERS NEAR
THE FRONT...STRETCHING FROM ACROSS SOUTHEAST GA ACROSS NORTHERN FL
AND A PORTION OF THE WESTERN FL PANHANDLE. THE MID LEVEL STEERING
CURRENT IS FAIRLY WEAK...SUPPORTING SLOW CELL MOVEMENT ALONG THE
FRONT OVER THE ABOVEMENTIONED LOCATIONS. THE BEST CONCENTRATION OF
CONVECTIVE CLUSTERS IS EXPECTED ACROSS THE EASTERN FL PANHANDLE
ACROSS PORTIONS OF THE WEST COAST OF THE PENINSULA. OVER THIS
AREA...1.50 TO 3.00 INCHES OF QPF WAS PLACED...WITH THE HIGHEST
AMOUNTS BETWEEN KCTY AND KBKV.

THERE IS REMARKABLE CONSISTENCY AMONG THE VARIOUS 00Z
REGIONAL/GLOBAL SOLUTIONS PLACING 3.00 TO 4.00 INCHES OF QPF IN
THE ABOVEMENTIONED LOCATIONS. SOME OF THE 00Z HIGH RESOLUTION
MODEL SOLUTIONS PLACED MAXIMUM NEAR 8 INCHES (INCLUDING THE 00Z
WRF ARW/NMMB AND 00Z REGIONAL GEM..WHICH WAS CLOSER TO 11 INCHES
OF QPF) IN THIS AREA...OR JUST OFFSHORE. THESE AMOUNTS ARE
PLAUSIBLE...GIVEN THE DEEP MOISTURE IN PLACE AND SLOW CELL/CLUSTER
MOVEMENT. HOWEVER...SINCE THERE IS SOME SPREAD AS TO WHETHER THE
HIGHEST QPF AMOUNTS OCCUR JUST OFFSHORE OR ON LAND OVER NORTHWEST
FL...A MORE CONSERVATIVE APPROACH WAS USED FOR THE WPC QPF. IN ANY
EVENT...THE POTENTIAL FOR HIGH RAINFALL RATES AND SLOW CELL
MOTIONS NECESSITATE A SLIGHT RISK AREA FOR PORTIONS OF NORTHWEST
FL.


...CENTRAL PLAINS/MIDWEST/GREAT LAKES...

SHORT WAVES IN THE MID LEVEL FLOW PUSH A COLD FRONT ACROSS THE
NORTHERN PLAINS INTO THE GREAT LAKES...CENTRAL PLAINS AND MIDWEST
DURING DAY 1. STRONG INSTABILITY AND SUFFICIENTLY DEEP MOISTURE
SHOULD RESULT IN ORGANIZED CONVECTION ALONG THE FRONT...WHICH
COULD PRODUCE LOCALLY HEAVY RAINFALL. FOR THE MOST PART...THERE
WAS DECENT MODEL AGREEMENT WITH THE MASS FIELDS OVER THE
REGION...SO THE WPC QPF WAS BASED ON A BLEND OF THE 00Z
NAM/GFS/ECMWF. THE QPF WAS AUGMENTED BY THE 00Z WRF ARW/NMMB AS
NEEDED TO BETTER DEFINE WHERE THE BEST QPF AMOUNTS WERE PLACED.

A STRONG SHORT WAVE TRACKING FROM SD INTO IA SHOULD PUSH ALONG A
SURFACE FRONT ACROSS THE NORTHERN PLAINS INTO THE GREAT LAKES AND
MIDWEST. AHEAD OF THE FRONT...MOISTURE SIPHONED FROM THE SOUTHERN
PLAINS ON A LOW LEVEL SOUTHWEST FLOW FEEDS CONVECTION DEVELOPING
IN THE PRESENCE OF STRONG INSTABILITY ACROSS NE/IA. THIS SHOULD
RESULT IN CLUSTERS OR LINES OF CONVECTION DEVELOPING AHEAD OF THE
FRONT IN THE PRESENCE OF DEEP MOISTURE (WITH PRECIPITABLE WATER
VALUES TOPPING 1.50 INCHES). MODEL SOUNDINGS SHOWED DRY MID LEVELS
AT THE TIME OF CONVECTION INITIATION...WHICH SUPPORTS LESS OF A
HEAVY RAIN THREAT. HOWEVER...THE COLUMN MOISTENS WITH TIME...AND
LOCALLY HEAVY RAINFALL BECOMES POSSIBLE AFTER 02/00Z ACROSS
PORTIONS OF SOUTHEAST NE INTO SOUTHWEST IA. ALONG THIS
TRACK...0.50 TO 0.75 INCHES OF QPF ARE EXPECTED.

IT SHOULD BE NOTED THAT BOTH THE 00Z NAM/GFS HAS MAXIMUM QPF
AMOUNTS OVER 2.00 INCHES ALONG THIS AXIS...THOUGH NOT IN THE SAME
LOCATION. THE HIGHER MOISTURE VALUES IN THE COLUMN COULD SUPPORT
LOCALLY HIGHER AMOUNTS...BUT THE CONVECTION SHOULD KEEPING MOVING
DUE TO STRONG MID LEVEL WINDS. WHILE LOCALLY HEAVY RAINFALL IS
POSSIBLE...ORGANIZED FLASH FLOODING IS NOT EXPECTED.


...NORTHEAST...

A SHORT WAVE IN THE FAST MID LEVEL FLOW TAPS INSTABILITY AND
SUFFICIENT MOISTURE FOR LOW TOPPED CONVECTION...MAINLY ACROSS NEW
ENGLAND DURING DAY 1. THERE WAS GENERALLY GOOD MODEL AGREEMENT ON
THE SEQUENCE OF EVENTS...THOUGH THERE WAS SOME SPREAD CONCERNING
HOW MUCH MOISTURE (AND ULTIMATELY INSTABILITY) WILL BE AVAILABLE
FOR QPF WITH DEVELOPING CONVECTION. THE 00Z ECMWF APPEARED TO BE
PRODUCING THE MOST INSTABILITY ACROSS NORTHERN NEW ENGLAND AHEAD
OF THE SHORT WAVE...WHICH MAY BE TOO AGGRESSIVE GIVEN THE MOISTURE
AND INSTABILITY PROFILES. BECAUSE OF THIS...THE WPC QPF WAS BASED
PRIMARILY ON A BLEND OF THE 00Z NAM/GFS.

A SHORT WAVE CROSSING ONTARIO/QUEBEC EARLY DURING DAY 1 TRACKS
ACROSS NORTHERN NEW ENGLAND AFTER 01/18Z. AHEAD OF THE SHORT WAVE
(AND A WEAK SURFACE REFLECTION)...THE LOW LEVEL FLOW BACKS ENOUGH
TO TAP PRECIPITABLE WATER VALUES NEAR 1.00 INCHES...WHICH IS
FUNNELED PRIMARILY INTO NORTHERN NEW ENGLAND. MODEL SOUNDINGS
SUGGESTED INSTABILITY MAY BE THE LIMITING FACTOR...AS THE SHEAR
PROFILE LOOKS FAVORABLE FOR SOME ORGANIZATION. THE BEST CONVECTIVE
ACTIVITY SHOULD CROSS NORTHERN NEW ENGLAND BEFORE 02/00Z. GIVEN
THE MID LEVEL FLOW...QPF AMOUNTS SHOULD BE LIMITED TO 0.25 INCHES
ACROSS NORTHERN VT/NORTHERN NH AND NORTHERN AND WESTERN ME.



DAYS 2/3...

THE WEST
~~~~~~~~
THE GUIDANCE HAS COME INTO MUCH BETTER AGREEMENT IN THIS REGION.
COMPROMISED BETWEEN THE 00Z WPC QPF/12Z AND 00Z ECMWF/00Z GFS/OLD
00Z GEFS-BASED REFORECAST PATTERN WISE.  ENERGY MOVING THROUGH THE
GREAT BASIN/NV EARLY ON COULD LEAD TO LOCALIZED PROBLEMS FROM AN
EXCESSIVE RAINFALL PERSPECTIVE AS 700 HPA INFLOW OF 15-25 KTS IS
PROGGED WHICH COULD ORGANIZE CONVECTION -- IT SHOULD NOT BE PULSE.
 FOR THE TIME BEING, HAVE NOT INCLUDED AN EXCESSIVE RAINFALL AREA.
 THIS WILL NEED TO BE EVALUATED BY LATER SHIFTS.


GREAT LAKES/MIDWEST
~~~~~~~~~~~~~~~~~~~
A VARIETY OF CONVECTIVE SYSTEMS ARE POSSIBLE IN THIS REGION AS A
FRONTAL BOUNDARY AND RESULTANT OUTFLOW BOUNDARIES FROM EARLIER
CONVECTION HELP FOCUS RAINFALL.  THE 06Z/12Z WPC QPF IS CLOSEST TO
A COMPROMISE OF THE 12Z AND 00Z ECMWF/00Z WPC QP
