AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
253 PM CDT SAT AUG 30 2014

.DISCUSSION...
THE 19Z SURFACE ANALYSIS AND AREA 88-D RETURNS ALL INDICATE THAT
SHOWERS AND STORMS WERE CONTINUING TO DEVELOP IN THE UNSEASONABLY
MOIST ATMOSPHERE ACROSS THE FORECAST AREA. TEMPS WERE RANGING FROM
85 TO AROUND 90 AT MOST LOCATIONS. EXPECT SHOWERS AND STORMS TO
CONTINUE TO DEVELOP THROUGH THE EVENING AND OVERNIGHT HOURS AS PWAT
VALUES ARE EXPECTED TO REMAIN AT AROUND TWO INCHES THROUGH 12Z
SUNDAY. A COUPLE OF SHORT WAVES WILL MOVE NORTH-NORTHEAST THROUGH
LOUISIANA AND INTO SOUTHERN ARKANSAS AND NORTHWEST MISSISSIPPI INTO
WEST TENNESSEE TONIGHT. THIS WILL FURTHER RESULT IN A SLOW INCREASE
IN SHOWERS AND STORMS OVERNIGHT AND WILL KEEP PRECIP CHANCES IN THE
LIKELY CATEGORY FOR THE FORECAST AREA TONIGHT.

THE MODELS ARE SIMILAR IN PROGRESSIVELY MOVING THE SHORT WAVES
NORTHEAST AWAY FROM THE FORECAST AREA INTO KENTUCKY BY BETWEEN 18Z
SUNDAY AND 00Z MONDAY. WILL TREND TOWARD LESSENING POPS AS THE DAY
CONTINUES TOWARD JUST CHANCE POPS FOR THE AFTERNOON. IN THE WAKE OF
THE SHORT WAVES...SLIGHT MID LEVEL RIDGING WILL OCCUR ACROSS THE
REGION ON MONDAY AND TUESDAY ACROSS THE TENNESSEE VALLEY. WILL KEEP
IN ONLY A SLIGHT CHANCE POP FOR THE FORECAST AREA MONDAY AND TUESDAY
AND HAVE SLIGHTLY BUMPED UP TEMPS THROUGH THIS TIME PERIOD WITH MORE
SUNSHINE EXPECTED.

DURING THIS SAME TIME PERIOD...THE MODELS ARE FAIRLY SIMILAR IN
MOVING A SHORT WAVE AT 500 MILLIBARS AND AN ASSOCIATED SURFACE COLD
FRONT SOUTHEAST THROUGH THE UPPER MIDWEST BY 00Z TUESDAY. THE COLD
FRONT IS EXPECTED TO MOVE FURTHER SOUTHEAST INTO THE GREAT LAKES
THROUGH OHIO VALLEY REGION BY AROUND 12Z TUESDAY. WEAK SURFACE HIGH
PRESSURE WILL FOLLOW THE SOUTHEAST PUSH OF THE COLD FRONT INTO THE
GREAT LAKES REGION BY 00Z WEDNESDAY. THE FRONTAL BOUNDARY WILL LOSE
ITS UPPER LEVEL SUPPORT AS IT MOVES INTO THE TENNESSEE VALLEY...AND
IS EXPECTED TO WASH OUT ACROSS MIDDLE TENNESSEE BY EARLY WEDNESDAY.
THE ECMWF MODEL AND TO A LESSER DEGREE...THE GFS MODEL...KEEP THE
REMNANTS OF THE FRONTAL BOUNDARY CLOSE TO THE FORECAST AREA BY
WEDNESDAY...SO EXPECT THAT THERE COULD BE SOME SCATTERED SHOWERS AND
STORMS BY WEDNESDAY AFTERNOON. WILL SLIGHTLY BUMP UP PRECIP CHANCES
FOR WEDNESDAY TOWARD GUIDANCE VALUES.

WILL CONTINUE WITH A MAINLY DIURNAL MENTION OF SHOWERS AND STORMS
DURING THE LATTER PART OF THE EXTENDED FORECAST PERIODS. HAVE
COMPROMISED BETWEEN THE WARMER GFS TEMPS VERSUS THE SLIGHTLY COOLER
ECMWF MODEL GUIDANCE INVOLVING EXTENDED TIME FRAME TEMP FORECAST.

THROUGH THE TAF PERIOD AT KHSV AND KMSL...BUT VIS COULD DROP TO MVFR
CONDITIONS IN STRONGER STORMS. THUNDERSTORMS WILL CONTINUE TOWARDS

THE MS AND TN VALLEY IS IN BETWEEN HIGH PRESSURE OFF IN THE ATLANTIC

OVER LA AND MS AHEAD OF THE TROUGH. A SMALL DISTURBANCE MOVING
THROUGH PROVIDED THE FEW SHOWERS SEEN AROUND THIS AREA THIS MORNING.
OTHERWISE THE MAJORITY OF THE PRECIP HAS STAYED TO OUR WEST THUS
FAR.

WITH THE SUN PEEKING OUT IN A FEW LOCATIONS...THIS WILL ALLOW FOR
ASSISTANCE IN INSTABILITY THIS AFTERNOON. CURRENT OBS SHOW DEW
POINTS IN THE HUN CWA HAVE IMPROVED AND ARE NOW AROUND 7O. SOUTHERLY

CAPE VALUES COULD GET UP TO 1000 TO 15000 J/KG AROUND THE TN VALLEY
THIS AFTERNOON. THE MAIN SHORT WAVE WILL MOVE IN LATER THIS
AFTERNOON/EVENING. AT THIS TIME...WOULD STILL BE LOOKING AT GUSTY
WINDS AND HEAVY DOWNPOURS TO OCCUR WITH STORMS AS THEY MOVE ACROSS
THE AREA.

AS FOR CHANGES IN THE GRIDS...LOWERED POPS FOR THIS MORNING AS WE
SEEMED TO BE TOO DRY AND STABLE TO GET ANY PRECIP TO MOVE EASTWARD

A RETURN TO WARMER AND GENERALLY DRIER WEATHER IS FORECAST FOR

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
401 AM CDT SAT AUG 30 2014

.DISCUSSION...
A DAY OF TRANSITION FROM A HOT/DRY PATTERN TO ONE MORE UNSETTLED...
AS RAIN CHANCES RETURN TO THE TENNESSEE VALLEY. THE UPPER RIDGE
THAT BROUGHT THE VERY WARM/HOT TEMPERATURES ACROSS THE REGION HAS
SHIFTED TO THE SE COAST...IN RESPONSE TO THE NORTHERN STREAM
DIPPING FURTHER SOUTHWARD OVER THE WESTERN AND CENTRAL CONUS. THE
WATER VAPOR LOOP DEPICTED A SERIES OF UPPER DISTURBANCES HEADED
EASTWARD TOWARD THE PACIFIC NW REGION...SOUTH OF A VORTEX SITUATED
ACROSS NORTHERN ALASKA. EAST OF THIS...A FEED OF MID/UPPER LEVEL
MOISTURE CONTINUED STREAMING NORTHWARD FROM THE GULF AND CENTRAL
AMERICA. AT THE SURFACE...A SOUTHERLY FLOW WAS ALSO BRINGING DEEPER
LOWER LEVEL GULF MOISTURE ACROSS THE REGION. DEWPOINTS AT OR ABOVE
70F WERE NOTED MAINLY SOUTH OF THE I-20 CORRIDOR. SHOWER ACTIVITY
ASSOCIATED WITH THE MOISTURE SURGE MOVING NORTHWARD WAS APPARENT
VIA REGIONAL RADAR WELL TO OUR SOUTH...AND BEGINNING TO SHOW ON OUR
HYTOP RADAR...S-SW OF THE RDA.

THUS THE WEEKEND TO `END` SUMMER 2014 WILL BE AN UNSETTLED ONE...AS
RAIN CHANCES INCREASE THROUGHOUT TODAY AND TONIGHT. GIVEN THE
SHOWER ACTIVITY APPROACHING FROM THE SOUTH...HAVE SCATTERED SHOWER
CHANCES THIS MORNING...BECOMING LIKELY THIS AFTERNOON AND EVENING.
BOTH THE NAM AND GFS FORECAST PRECIP WATER AMOUNTS RISING AT OR
ABOVE 2 INCHES THIS AFTERNOON/EVENING. THUS GUSTY WINDS IN THE
40-50 MPH RANGE...LOCALLY HEAVY RAINFALL...AND FREQUENT LIGHTNING
WILL ACCOMPANY THE STRONGER STORMS. IN ADDITION...A BIT MORE SHEAR
WAS FORECAST FOR OUR NW ALABAMA GROUP...SO A STRONG STORM CANNOT BE
RULED OUT. EVEN WITH A POTENTIAL FOR HEAVY RAINS...THE ON-GOING DRY
GROUND SHOULD BE ABLE TO ABSORB THE FIRST DOSES OF RAINFALL INTO
THE EVENING. BUT TRAINING/REPEATING EPISODES OF HEAVY RAIN COULD
CHANGE THIS...SOMETHING WE WILL MONITOR.

RAIN CHANCES WILL DIMINISH FOR THE VALLEY EAST OF THE NW ALABAMA
DURING SUNDAY...AS A MOISTURE MAXIMUM ADVECTS TO THE NORTH. LEFT IN
LIKELY RAIN CHANCES ACROSS FAR NW ALABAMA ON SUN... GIVEN A SIGNAL
OF SOMEWHAT BETTER LIFT/MOISTURE CONVERGENCE OVER THIS AREA.
THROUGH MONDAY...HAVE RAINFALL TOTALS ACROSS THE AREA RANGING FROM
OVER 1/2 OF AN INCH OVER NE AL...TO 1.3 OVER THE NW.

A RETURN TO WARMER AND GENERALLY DRIER WEATHER IS FORECAST FOR
LABOR DAY MON...AS A SOUTHERLY FEED FROM THE SOUTH CONTINUES. WITH
MORE SUN THAN CLOUDS...HIGH TEMPERATURES ON THE HOLIDAY SHOULD WARM
BACK INTO THE LOWER 90S (AFTER A BRIEF "COOL DOWN" IN THE 80S
DURING THE WEEKEND). STAYED CLOSER TO THE SLIGHTLY MILDER ECMWF...
WITH LOWER 90 HIGH TEMPERATURES THE RULE FOR MUCH OF NEXT WEEK.
APPARENT TEMPERATURES WILL RISE INTO THE MID/UPPER 90S FOR MUCH OF
THE PERIOD...WITH SOME NEAR 100 READINGS NEXT TUE/WED. ISOLATED
SHOWER/T-STORM CHANCES WILL CONTINUE DURING THE PERIOD.

EXPECTED TO MOVE ACROSS MIDDLE TENNESSEE BY WEDNESDAY...AND MAY LEAD
TO A LOW CHANCE POP FOR WEDNESDAY. HAVE MOVED UP PRECIP CHANCES FROM
THE SLIGHT CATEGORY TO THE CHANCE CATEGORY FOR THIS TIME PERIOD DUE
TO THE EXPECTED TRIGGER...DECENT LOW LEVEL MOISTURE AND HOT TEMPS.

WILL FURTHER MAINTAIN AT LEAST SLIGHT CHANCE POPS THROUGH THE END OF

NEARLY 1.80 INCHES BY 12Z SATURDAY.

WILL CONTINUE WITH LIKELY PRECIP CHANCES ESPECIALLY BY SATURDAY
AFTERNOON AND CONTINUE GOING POPS INTO SUNDAY FOR THE FORECAST AREA.
DUE TO HIGH PWAT VALUES ABOVE TWO INCHES...THERE COULD DEFINITELY BE
SOME HEAVY RAINFALL BETWEEN LATE SATURDAY AND INTO SUNDAY MORNING.
THE SERIES OF SHORT WAVES ARE EXPECTED TO SLIDE NORTHEAST OF THE
FORECAST AREA BY BETWEEN 12Z AND 18Z MONDAY. HAVE SHARPLY REDUCED
PRECIP CHANCES BY LABOR DAY INTO THE 20 PERCENT CATEGORY FOR MAINLY
DIURNAL AFTERNOON/EVENING STORMS.

THE ECMWF AND GFS MODELS ARE SIMILAR AFTER MONDAY IN DEVELOPING A MID
TO UPPER LEVEL RIDGE AXIS AGAIN ACROSS THE REGION. THERE WILL BE
LESSENING PRECIP CHANCES EXPECTED INTO MID WEEK AND MORE WARM AIR
EXPECTED INTO THE MID LEVELS. WILL SLIGHTLY INCREASE TEMPS INTO THE
MID 90S THROUGH THE REST OF THE EXTENDED FORECAST PERIODS. THE MODELS
ATTEMPT TO DROP A WEAK FRONTAL BOUNDARY OUT OF THE CENTRAL PLAINS
STATES THROUGH THE GREAT LAKES REGION ON TUESDAY...TO THE LOWER OHIO
VALLEY BY 12Z WEDNESDAY. A WEAK SHORT WAVE AT 500 MILLIBARS IS
EXPECTED TO MOVE ACROSS MIDDLE TENNESSEE BY WEDNESDAY...AND MAY LEAD
TO A LOW CHANCE POP FOR WEDNESDAY. HAVE MOVED UP PRECIP CHANCES FROM
THE SLIGHT CATEGORY TO THE CHANCE CATEGORY FOR THIS TIME PERIOD DUE
TO THE EXPECTED TRIGGER...DECENT LOW LEVEL MOISTURE AND HOT TEMPS.

WILL FURTHER MAINTAIN AT LEAST SLIGHT CHANCE POPS THROUGH THE END OF
THE EXTENDED FORECAST PERIODS MAINLY DUE TO DIURNAL SHOWERS AND
STORMS BEING A POSSIBILITY. WILL KEEP TEMPS GENERALLY AS A COMPROMISE
BETWEEN THE SLIGHTLY COOLER ECMWF MODEL NUMBERS AND THE WARMER GFS

218 PM CDT FRI AUG 29 2014

.DISCUSSION...
THE 19Z SURFACE ANALYSIS...IR/VISIBLE SATELLITE IMAGERY AND FORECAST
SOUNDINGS INDICATE THAT THE FORECAST AREA IS STILL SOMEWHAT UNDER THE
INFLUENCE OF A WEAKENING MID TO UPPER LEVEL RIDGE OF HIGH PRESSURE.
TEMPS WERE RANGING FROM THE UPPER 80S IN NORTHEAST ALABAMA...TO THE
LOWER 90S ELSEWHERE. LOW LEVEL WINDS WERE BECOMING MORE SOUTHERLY
ACROSS THE AREA...WHICH WILL EVENTUALLY RESULT IN INCREASING
DEWPOINTS AND LOW LEVEL MOISTURE BY TONIGHT.

THE FIRST IN A SERIES OF SHORT WAVES AT 500 MILLIBARS WILL MOVE
NORTH-NORTHEAST OUT OF LOUISIANA AND INTO SOUTHWEST ARKANSAS...TOWARD
WESTERN MISSISSIPPI BY 12Z SATURDAY. HAVE KEPT PRECIP CHANCES AS IS
TONIGHT ACROSS THE FORECAST AREA...AS IT WILL LIKELY BE CLOSER TO
MORNING BEFORE ANY ORGANIZED AREAS OF SHOWERS/STORMS MAKE IT INTO THE

.DISCUSSION...
/ISSUED 522 AM CDT FRI AUG 29 2014/
ANALYSIS OF EVENING SOUNDING DATA AND WV SATELLITE IMAGERY INDICATE
THAT A SEASONABLY STRONG MID-LEVEL RIDGE REMAINS CENTERED ACROSS
THE SOUTHEASTERN ATLANTIC COAST THIS MORNING...AND THIS FEATURE IS
EXPECTED TO REMAIN IN PLACE TODAY AND TONIGHT. FURTHER UPSTREAM...A
WEAK 500-MB SHORTWAVE TROUGH CURRENTLY ACROSS THE CENTRAL PLAINS IS
PROGGED TO SHIFT EASTWARD ACROSS THE MISSOURI VALLEY...WITH A RATHER
STRONG BELT OF MID-TROPOSPHERIC SOUTHWESTERLY WINDS EXPECTED TO
EVOLVE WITHIN THE INCREASING HEIGHT GRADIENT BETWEEN THIS FEATURE AND
THE RIDGE TO THE SOUTHEAST. ANOTHER WEAK DISTURBANCE OVER THE LOWER
MISSISSIPPI VALLEY WILL LIFT NORTHEASTWARD ACROSS WESTERN TENNESSEE
AND KENTUCKY LATER TODAY IN THIS REGIME...BUT WITH STRONGEST FORCING
FOR UVM REMAINING WEST OF THE REGION ONLY AN INCREASE IN CIRROFORM
CLOUDS IS EXPECTED. DUE TO THE HIGH/THIN NATURE OF THE CLOUD
COVER...THIS WILL HAVE ONLY A MINOR IMPACT ON HIGH TEMPERATURES...
WITH VALUES AROUND A DEGREE OR SO COOLER THAN THOSE OBSERVED ON
THURSDAY.

FOR THE REMAINDER OF THE SHORT TERM PERIOD...GUIDANCE FROM GFS/NAM IS
IN GOOD AGREEMENT THAT THE CENTRAL PLAINS MID-LEVEL WAVE WILL SHEAR
APART AND LIFT NORTHEASTWARD ACROSS THE UPPER MISSISSIPPI
VALLEY/GREAT LAKES AND INTO SOUTHERN QUEBEC BY SUNDAY EVENING. THIS
WILL EFFECTIVELY FORCE THE SOUTHEASTERN CONUS RIDGE TO DEAMPLIFY AND
EXPAND SOUTHWESTWARD INTO THE WESTERN GULF...SETTING UP A STRONGER
SOUTHWEST FLOW ALOFT AND RICH TROPICAL MOISTURE FETCH ACROSS THE
LOCAL AREA. SHOWERS/THUNDERSTORMS WILL LIKELY BEGIN TO INCREASE FROM
THE SOUTHWEST VERY EARLY SATURDAY MORNING...AS PWATS RISE TO 2+
INCHES AND WEAK ISENTROPIC ASCENT BECOMES EVIDENT BETWEEN THE
300-320K SURFACES. ALTHOUGH SOME MODEL GUIDANCE SUGGESTS THE PASSAGE
OF A WEAK MID-LEVEL VORT MAX OVERNIGHT...IT APPEARS THAT MOST OF THE
ATMOSPHERIC LIFT WILL BE GENERATED BY VEERING WINDS/WARM ADVECTION
WITHIN THE LOWER TROPOSPHERE AND WILL KEEP POPS IN THE CHANCE RANGE
AS A RESULT. FURTHERMORE...A LINGERING WEDGE OF DRY AIR MAY LIMIT
THE NORTHEASTWARD EXTENT OF PRECIPITATION ACROSS NE ALABAMA/SRN
TENNESSEE. GLOBAL MODELS CONTINUE TO GENERATE A STRONGER
CONVECTIVELY-INDUCED VORT MAX OVER THE NW GULF COAST TONIGHT...WHICH
WILL LIKELY LIFT NORTHEASTWARD INTO THE LOWER MISSISSIPPI VALLEY AND
BEGIN TO ENHANCE RAIN CHANCES FURTHER ACROSS THE NW HALF OF THE
FORECAST AREA TOMORROW AFTERNOON. ACROSS THE SOUTHEAST HALF OF THE
AREA...INFLUENCE FROM THE SOUTHEASTERN CONUS RIDGE WILL BE STRONGER
AND HAVE REDUCED POPS INTO THE CHANCE RANGE. THIS VORT MAX IS
EXPECTED TO BECOME INCREASINGLY STRETCHED/SHEARED AS IT LIFTS
NORTHEASTWARD...BUT WILL LIKELY CONTINUE TO PROVIDE A HIGHER COVERAGE
OF SHOWERS/STORMS FOR THE NW HALF OF THE AREA ON SATURDAY
NIGHT/SUNDAY MORNING. CONDITIONS WILL IMPROVE FOR ALL LOCATIONS BY
SUNDAY AFTERNOON...AS THE REMNANTS OF THE WAVE LIFT NORTHEASTWARD
AWAY FROM THE AREA. THICK CLOUDS WILL KEEP HIGHS IN THE MID 80S
TOMORROW...WITH LOWER 90S POSSIBLE SUNDAY AFTERNOON AS CLOUDS
DIMINISH. LOWS SATURDAY/SUNDAY MORNINGS WILL BE IN THE UPPER
60S/LOWER 70S.

SOUTHWEST FLOW ALOFT WILL PERSIST ACROSS THE CENTRAL TENNESSEE
VALLEY ON SUNDAY NIGHT...WITH THE POTENTIAL FOR ANOTHER DISTURBANCE
WARRANTING A LOW CHANCE POP AT THIS TIME. HOWEVER...CONDITIONS WILL
BEGIN TO CHANGE FROM MONDAY THROUGH THE REMAINDER OF THE EXTENDED
PERIOD...AS THE SUBTROPICAL RIDGE EXPANDS WESTWARD TO ENCOMPASS MOST
AREAS FROM THE SOUTHERN PLAINS TO THE SOUTHEASTERN ATLANTIC COAST.
FORECAST SOUNDINGS SUGGEST THAT PWATS WILL FALL INTO THE 1.4-1.6 INCH
RANGE DURING THIS PERIOD...AND WITH NO CLEAR EVIDENCE OF SYNOPTIC
SCALE FORCING FOR UVM EXPECT ONLY ISOLATED DIURNAL CONVECTION AT
BEST. HIGH TEMPERATURES WILL WARM BACK INTO THE LOWER/MID 90S...BUT
DEWPOINTS WILL BE MUCH HIGHER THAN WHAT WE HAVE EXPERIENCED FOR THE

FORECAST AREA TOMORROW AFTERNOON. ACROSS THE SOUTHEAST HALF OF THE
AREA...INFLUENCE FROM THE SOUTHEASTERN CONUS RIDGE WILL BE STRONGER
AND HAVE REDUCED POPS INTO THE CHANCE RANGE. THIS VORT MAX IS
EXPECTED TO BECOME INCREASINGLY STRETCHED/SHEARED AS IT LIFTS
NORTHEASTWARD...BUT WILL LIKELY CONTINUE TO PROVIDE A HIGHER COVERAGE
OF SHOWERS/STORMS FOR THE NW HALF OF THE AREA ON SATURDAY
NIGHT/SUNDAY MORNING. CONDITIONS WILL IMPROVE FOR ALL LOCATIONS BY
SUNDAY AFTERNOON...AS THE REMNANTS OF THE WAVE LIFT NORTHEASTWARD
AWAY FROM THE AREA. THICK CLOUDS WILL KEEP HIGHS IN THE MID 80S
TOMORROW...WITH LOWER 90S POSSIBLE SUNDAY AFTERNOON AS CLOUDS
DIMINISH. LOWS SATURDAY/SUNDAY MORNINGS WILL BE IN THE UPPER
60S/LOWER 70S.

SOUTHWEST FLOW ALOFT WILL PERSIST ACROSS THE CENTRAL TENNESSEE
VALLEY ON SUNDAY NIGHT...WITH THE POTENTIAL FOR ANOTHER DISTURBANCE
WARRANTING A LOW CHANCE POP AT THIS TIME. HOWEVER...CONDITIONS WILL
BEGIN TO CHANGE FROM MONDAY THROUGH THE REMAINDER OF THE EXTENDED
PERIOD...AS THE SUBTROPICAL RIDGE EXPANDS WESTWARD TO ENCOMPASS MOST
AREAS FROM THE SOUTHERN PLAINS TO THE SOUTHEASTERN ATLANTIC COAST.
FORECAST SOUNDINGS SUGGEST THAT PWATS WILL FALL INTO THE 1.4-1.6 INCH
RANGE DURING THIS PERIOD...AND WITH NO CLEAR EVIDENCE OF SYNOPTIC
SCALE FORCING FOR UVM EXPECT ONLY ISOLATED DIURNAL CONVECTION AT
BEST. HIGH TEMPERATURES WILL WARM BACK INTO THE LOWER/MID 90S...BUT
DEWPOINTS WILL BE MUCH HIGHER THAN WHAT WE HAVE EXPERIENCED FOR THE
PAST COUPLE OF DAYS -- LEADING TO HEAT INDEX VALUES IN THE 100-105
DEGREE RANGE.

SOUTH INTO OUR FORECAST AREA...SKIES WERE MOSTLY SUNNY ACROSS
SOUTHERN MIDDLE TENNESSEE AND NORTHERN ALABAMA...WITH TEMPS RANGING
FROM THE UPPER 80S TO THE LOWER-MID 90S.

A MOSTLY CLEAR AND MILD NIGHT IS EXPECTED TONIGHT ACROSS THE FORECAST

OVER NORTHWESTERN ALABAMA...WHICH HAD MORE MORNING CUMULUS
DEVELOPMENT YESTERDAY. A WEAK FRONTAL BOUNDARY WILL LINGER WELL TO

HIGH PRESSURE REMAINS IN CONTROL OF THE WEATHER ACROSS THE TENNESSEE
VALLEY THIS MORNING. FOG...PARTICULARLY DENSE IN THE SCOTTSBORO AREA
EARLIER THIS MORNING HAS LIFTED. BASED ON CURRENT TEMPERATURES AT 10
AM AND ABUNDANT SUNSHINE EXPECTED...EXPECT HIGHS TO REACH THE 90 TO
95 DEGREE RANGE IN MOST LOCATIONS. IT WILL FEEL A GOOD BIT WARMER
OVER NORTHWESTERN ALABAMA...WHICH HAD MORE MORNING CUMULUS
DEVELOPMENT YESTERDAY. A WEAK FRONTAL BOUNDARY WILL LINGER WELL TO
OUR NORTH OVER SOUTHERN KENTUCKY AND EXTREME NORTHERN TENNESSEE
TODAY. THIS MAY SINK SLIGHTLY FURTHER SOUTH AND GIVE THE NASHVILLE
AREA SOME ISOLATED STORM DEVELOPMENT LATER THIS AFTERNOON. DRIER AIR
IN PLACE...ESPECIALLY OVER NORTHERN ALABAMA...WILL KEEP ANY
CONVECTION FROM DEVELOPING OVER OUR SOUTHERN MIDDLE TENNESSEE
COUNTIES AND NORTHERN ALABAMA.

DESPITE SOME MUGGY CONDITIONS EARLY THIS MORNING...MIXING SHOULD
DROP DEWPOINTS SIGNIFICANTLY AS THE DAY PROGRESSES...MUCH LIKE

SHORT TERM MODELS REMAIN IN GOOD AGREEMENT IN DEPICTING A STRONG MID-
LEVEL HIGH PRESSURE CELL TO BUILD ACROSS NORTH/CENTRAL FLORIDA THIS
MORNING...AS A 500-MB TROUGH CONTINUES TO ADVANCE EASTWARD ACROSS THE
CENTRAL ROCKIES. A BROAD INVERTED TROUGH LOCATED BETWEEN THESE TWO
FEATURES CURRENTLY EXTENDS FROM THE WESTERN GULF OF MEXICO NORTH-
NORTHEASTWARD INTO THE MISSISSIPPI DELTA REGION...BUT WILL HAVE
LITTLE IF ANY IMPACT ON THE LOCAL WEATHER CONDITIONS TODAY AS
SUBSIDENCE ASSOCIATED WITH THE SOUTHEASTERN RIDGE WILL DOMINATE.
ASIDE FROM A FEW HIGH-LEVEL CIRRUS CLOUDS...MOSTLY SUNNY SKIES WILL
PREVAIL WITH TEMPERATURES WARMING INTO THE MID 90S. FORTUNATELY IT
APPEARS THAT BOUNDARY LAYER DEWPOINTS WILL MIX OUT INTO THE UPPER
50S/LOWER 60S PROVIDING LOWER HEAT INDICES. ELEVATED WARM ADVECTION
AND AT LEAST WEAK LOW-LEVEL CONVERGENCE TO THE NORTH OF THE REGION
MAY SUPPORT ISOLATED/WIDELY SCATTERED SHOWERS AND STORMS ACROSS
MIDDLE TENNESSEE AND THE CUMBERLAND PLATEAU...AND HAVE INCLUDED A
VERY LOW POP FOR OUR TENNESSEE COUNTIES THIS AFTERNOON TO REFLECT
THIS.

CONSENSUS OF NWP GUIDANCE SUGGESTS THAT THE ROCKIES MID-LEVEL TROUGH
WILL GRADUALLY SHIFT EASTWARD INTO THE CENTRAL PLAINS TONIGHT WHILE
THE ANTICYCLONE ACROSS NORTH/CENTRAL FLORIDA BEGINS TO BUILD
NORTHWARD ALONG THE COASTS OF NC/SC/GA. AS THIS OCCURS...THE NORTHERN
PORTION OF THE INVERTED TROUGH WILL BECOME DETACHED FROM THE
REMAINDER OF THE TROUGH AXIS AND LIFT NORTHWARD OVER THE LOWER
MISSISSIPPI VALLEY AND EVENTUALLY INTO THE OHIO VALLEY BY FRIDAY
EVENING. SYNOPTIC SCALE FORCING ASSOCIATED WITH THIS FEATURE WILL BE
RATHER WEAK AND DISPLACED TO THE WEST OF THE FORECAST AREA...AND ITS
PASSAGE SHOULD THEREFORE RESULT IN ONLY A MODEST INCREASE IN HIGH
CLOUDS BY LATE FRIDAY AFTERNOON. HOWEVER...THE INCREASE IN CLOUDS
WILL LIKELY NOT OCCUR EARLY ENOUGH TO PREVENT TEMPERATURES FROM
WARMING INTO THE MID 90S ONCE AGAIN. A NOTICEABLE INCREASE IN LOW-
LEVEL SOUTHERLY WINDS TOMORROW WILL BEGIN TO ADVECT MOISTURE
NORTHWARD ACROSS THE REGION BY TOMORROW AFTERNOON...AND HEAT INDEX
VALUES MAY BE A BIT HIGHER AS A RESULT.

THE CENTRAL PLAINS MID-LEVEL TROUGH IS FORECAST TO SLOWLY SHEAR APART
AND LIFT NORTHEASTWARD INTO THE CENTRAL GREAT LAKES BY SATURDAY
EVENING. INCREASING SOUTH-SOUTHWESTERLY GRADIENT FLOW ALOFT BETWEEN
THIS FEATURE AND THE SOUTHEASTERN ATLANTIC COAST MID-LEVEL HIGH WILL
PROMOTE A RAPID RETURN OF DEEP-LAYER MOISTURE BY LATE FRIDAY
NIGHT...WITH PWATS RISING INTO THE 2+ INCH RANGE FOR MOST OF THE
AREA. STRONG WARM/MOIST ADVECTION ALONE WILL WARRANT AT LEAST LOW
CHANCE POPS FOR SHOWERS/THUNDERSTORMS BETWEEN 6-12Z SATURDAY...WITH
COVERAGE OF PRECIPITATION EXPECTED TO INCREASE SUBSTANTIALLY DURING
THE DAY ON SATURDAY AS THESE PROCESSES CONTINUE. VARIOUS GLOBAL
MODELS ALSO CONTINUE TO INDICATE STRONGER SYNOPTIC SCALE ASCENT
ARRIVING DURING THE PERIOD FROM LATE SATURDAY THROUGH SUNDAY MORNING
-- POSSIBLY IN THE FORM OF ONE OR MORE CONVECTIVELY ENHANCED
VORTICITY MAXIMA EMANATING FROM WIDESPREAD CONVECTION ACROSS THE
NORTH CENTRAL GULF. THUS...WILL MAINTAIN LIKELY POPS THROUGH SUNDAY
ALTHOUGH ACTIVITY MAY BE DIMINISHING DURING THE AFTERNOON HOURS.

FOR THE REMAINDER OF THE EXTENDED PERIOD...FLOW CONDITIONS ACROSS
MUCH OF THE CONUS WILL BE DOMINATED BY THE SOUTHERN PORTION OF A
STRONG LONGWAVE TROUGH -- WHICH IS FORECAST TO SPREAD EASTWARD ACROSS
CANADA THROUGH MID-WEEK -- AND A RETROGRADING SUBTROPICAL RIDGE WHICH
WILL ENCOMPASS MUCH OF THE SOUTHERN CONUS BETWEEN 30-35 N LATITUDE.
WITH THIS IN MIND...WILL ONLY CARRY A SLIGHT CHANCE POP FROM MONDAY-
TUESDAY WITH HIGH TEMPERATURES WARMING BACK INTO THE LOWER 90S. AS
THE CENTER OF THE RIDGE AXIS BECOMES ESTABLISHED WEST OF THE REGION
BY MID-WEEK...A WEAK NORTHWEST FLOW MAY BE INDUCED OVER THE TENNESSEE
VALLEY...RESULTING IN A SLIGHTLY HIGHER PROBABILITY FOR SHOWERS AND
STORMS.

MID-LEVEL RIDGING OVER THE SE STATES REMAINED IN PLACE...HELPING
TO CONTINUE GENERALLY DRY CONDITIONS...AND WARM TO HOT TEMPERATURES
ACROSS THE TENNESSEE VALLEY. WELL TO OUR EAST BETWEEN THE OUTER BANKS
AND BERMUDA...HURRICANE CRISTOBOL CONTINUED CHURNING ACROSS THE
WESTERN ATLANTIC WHILE MOVING TO THE NNE...WITH NO IMPACT FROM IT
ACROSS THIS AREA. TO OUR WEST...A TROUGH AMPLIFYING ACROSS THE
INTERMOUNTAIN WEST WILL MOVE EASTWARD...AND RETURN RAIN CHANCES TO
THIS REGION FOR THE UPCOMING WEEKEND.

BEFORE THEN...ANOTHER NIGHT...WITH MILD TO WARM LATE SUMMER TEMPS IS
EXPECTED. OVERNIGHT LOWS SHOULD COOL INTO THE MID/UPPER 60S WITH
LIGHT WINDS. THE LIGHT WINDS AND CLEAR SKIES...AND SLIGHTLY HIGHER
DEWPOINT VALUES COULD RESULT IN MORE PATCHY FOG DEVELOPING DURING THE
OVERNIGHT AND DAYBREAK HOURS. THE MORE FOG PRONE AREAS...LIKE NEAR
BODIES OF WATER AND SHELTERED LOCATIONS WILL HAVE BETTER ODDS OF

THE ON-GOING FORECASTS FROM THE DAY SHIFT HAVE THE MAIN PARAMETERS

/ISSUED 923 PM CDT WED AUG 27 2014/
MID-LEVEL RIDGING OVER THE SE STATES REMAINED IN PLACE...HELPING
TO CONTINUE GENERALLY DRY CONDITIONS...AND WARM TO HOT TEMPERATURES
ACROSS THE TENNESSEE VALLEY. WELL TO OUR EAST BETWEEN THE OUTER BANKS
AND BERMUDA...HURRICANE CRISTOBOL CONTINUED CHURNING ACROSS THE
WESTERN ATLANTIC WHILE MOVING TO THE NNE...WITH NO IMPACT FROM IT
ACROSS THIS AREA. TO OUR WEST...A TROUGH AMPLIFYING ACROSS THE
INTERMOUNTAIN WEST WILL MOVE EASTWARD...AND RETURN RAIN CHANCES TO
THIS REGION FOR THE UPCOMING WEEKEND.

BEFORE THEN...ANOTHER NIGHT...WITH MILD TO WARM LATE SUMMER TEMPS IS
EXPECTED. OVERNIGHT LOWS SHOULD COOL INTO THE MID/UPPER 60S WITH
LIGHT WINDS. THE LIGHT WINDS AND CLEAR SKIES...AND SLIGHTLY HIGHER
DEWPOINT VALUES COULD RESULT IN MORE PATCHY FOG DEVELOPING DURING THE
OVERNIGHT AND DAYBREAK HOURS. THE MORE FOG PRONE AREAS...LIKE NEAR
BODIES OF WATER AND SHELTERED LOCATIONS WILL HAVE BETTER ODDS OF
EXPERIENCING FOG.

THE ON-GOING FORECASTS FROM THE DAY SHIFT HAVE THE MAIN PARAMETERS
IN GOOD SHAPE...THEREFORE NO CHANGES WERE NEEDED.

PACKAGE. OTHERWISE NOT A BAD AUGUST DAY WITH TEMPS IN THE MID/UPPER
80S AND DEWPOINTS IN THE LOWER 60S. TONIGHT WILL ALSO BE A QUIET
NIGHT WITH LOWS DROPPING INTO THE MID 60S. THURSDAY LOOKS TO BE
DRY BUT A LITTLE WARMER THAN TODAY...WITH HIGHS IN THE LOW/MID 90S.
THURSDAY NIGHT WILL CONTINUE DRY WITH LOWS AGAIN MAINLY IN THE MID
60S.

FRIDAY...KEPT A SLIGHT POP IN FOR FRIDAY NIGHT BUT WOULD NOT BE
SURPRISED IF THE ENTIRE DAY/NIGHT WOULD BE DRY...AS MODELS ARE
HINTING AT HOLDING OFF THE TIMING OF THE PCPN.

SATURDAY/SUNDAY...THE UPPER RIDGE MOVES EAST ALLOWING FOR A COUPLE OF
UPPER TROFS TO APPROACH THE CWA OVER THE WEEKEND. TIMING OF PCPN THIS
FAR OUT IS TRICKY ATTM...BUT IT DOES LOOK LIKE THE CHC OF PCPN WILL
BE INCREASING. SINCE PW`S ARE ARND 2 INCHES LOCALIZED HVY RAIN LOOKS
LIKE A GOOD BET. ALSO CANT RULE OUT SOME STRONG WIND GUSTS WITH THE
HVY RAIN. HOWEVER ATTM NOT EXPECTING WIDESPREAD SVR WX OVER THE
HOLIDAY WEEKEND.

BY MONDAY THE UPPER WAVES WILL BE EAST OF THE CWA. THUS EXPECT
THE SHRA/TSRA ACTIVITY TO BEGIN TO TAPER OFF. HOWEVER A CDFNT IS NOW
APPROACHING FROM THE MIDWEST. BY TUESDAY/WEDNESDAY THE CDFNT IS
PROGGED TO SAG CLOSER TOWARDS THE TN VALLEY...THIS WILL KEEP A LOW
POP IN FOR THIS TIMEFRAME.
