/ISSUED 233 AM CDT SAT JUL 26 2014/
WATER VAPOR AND MODEL ANALYSIS INDICATES A LARGE UPPER LEVEL
ANTICYCLONE OVER THE SOUTHERN CONUS. A POTENT UPPER LOW WAS
POSITIONED TO ITS NORTH OVER SASKATCHEWAN WITH A JET CORE IN BETWEEN
FROM THE NRN ROCKIES THRU THE GREAT LAKES AND OHIO VALLEY.

HOT WEATHER IS EXPECTED TODAY AND SUNDAY, WITH INCREASING MOISTURE
OWING TO HEAT INDEX VALUES OF 100-105F. WE SPLIT THE DIFFERENCE ON
THE MOS TEMPS (GFS HAS BEEN TYPICALLY TOO WARM), BUT THE ADVECTION
OF 850MB TEMPS IN THE L-M20S MAKE READINGS IN THE L-M90S SEEM VERY
PLAUSIBLE. FORECAST SOUNDINGS INDICATE A FORMIDABLE CAPPING INVERSION
TODAY, SO FEW CLOUDS ARE EXPECTED. DEW POINTS OF NEAR OR JUST ABOVE
70F WILL RETURN ON SUNDAY AS PERSISTENT S-SWLY FLOW OCCURS. THE CAP
MAY YET BE STRONG ENOUGH TO PREVENT DEEP CONVECTION, BUT WILL KEEP
ISOLATED T AS A POSSIBILITY DURING THE LATE AFTERNOON. IF THE CAP CAN
BREAK, INSTABILITY/CAPE AND A DRIER 8-5H LAYER WOULD SUPPORT
DOWNBURST ACTIVITY.

THE COLD FRONT ARRIVES SUNDAY EVENING IN SOUTHERN TN. ROBUST
CONVECTIVE ACTIVITY LOOKS TO BE ONGOING ALONG THE FRONT OVER EASTERN
TN WHICH SHOULD TEND TO BACK-BUILD WWD INTO THE FAVORABLE 25-35KT
LOW LEVEL INFLOW (9-8H LEVELS) AND THETA-E RIDGE POSN. THE CAPPING
INVERSION WILL LIKELY HOLD DEVELOPMENT BACK UNTIL THIS OCCURS. THE
CAP ALSO LENDS TO LOWER CONFIDENCE AS TO AREAL COVERAGE OF STORMS
SUNDAY NIGHT. MID LEVEL NWLY FLOW OF 30-35KT WILL INCREASE EFFECTIVE
BULK SHEAR VALUES, BUT NOT CERTAIN IF THIS WILL BE SUFFICIENT FOR A
SUPERCELL STORM MODE VS MULTI-CELL CLUSTERS AS UPPER LEVEL WINDS
REMAIN RELATIVELY WEAK. THE SPC OUTLOOK EMPHASIZING AREAS TO OUR NE
LOOKS GOOD, BUT A COUPLE OF SEVERE STORMS MAY OCCUR IN OUR AREA
SUNDAY NIGHT AS WELL.

AS HAS BEEN ADVERTISED, THE MEDIUM RANGE MODELS CONTINUE TO TAKE THE
UPPER LOW SE INTO THE A DEEPER TROF POSITION BY EARLY NEXT WEEK OVER
THE EASTERN CONUS WHILE THE RIDGE RETROGRADES WWD A ACROSS THE
ROCKIES/SWRN CONUS. THIS WILL BRING ANOTHER WELCOME PERIOD OF BELOW
AVERAGE TEMPS AND LOWER HUMIDITY THRU THE MIDDLE TO END OF NEXT WEEK.

A MODERATELY STRONG NORTHWEST FLOW ALOFT PREVAILS ACROSS THE CENTRAL
TENNESSEE VALLEY THIS MORNING...WITH THE MID-LEVEL TROUGH AXIS NOW
LOCATED TO THE SOUTHEAST OF THE LOCAL AREA. THIS HAS TRANSLATED TO
VERY PLEASANT EARLY MORNING TEMPERATURES/DEWPOINTS FOR LATE
JULY...WITH PATCHY VALLEY FOG LEADING TO VISIBILITY REDUCTIONS
GENERALLY IN THE 3-5 MILE RANGE.

DURING THE PERIOD FROM TODAY THROUGH SATURDAY...MODELS REMAIN
CONSISTENT IN FORECASTING A STRONG SUBTROPICAL RIDGE -- CURRENTLY
CENTERED ACROSS NEW MEXICO AND THE TEXAS PANHANDLE -- TO BUILD
EASTWARD OVER THE CENTRAL PLAINS AND INTO THE LOWER MISSISSIPPI
VALLEY. SUBSTANTIAL HEIGHT RISES ALOFT WILL RESULT IN THE DEVELOPMENT
OF A PRONOUNCED INVERSION IN THE 850-800 MB LAYER...WHICH WILL WORK
IN TANDEM WITH THE DRY AIRMASS IN PLACE TO LIMIT PRECIPITATION
CHANCES TO A SILENT 5 PERCENT. A COUPLE OF WEAK VORTICES DROPPING
SOUTHWARD IN THE NORTHERLY FLOW ALOFT MAY BRING PERIODS OF ENHANCED
HIGH-LEVEL CLOUDS COVER TO THE REGION TODAY/TONIGHT...BUT WE ARE
GENERALLY EXPECTING MOSTLY CLEAR SKIES WITH THE EXCEPTION OF
SCATTERED CUMULUS THIS AFTERNOON. BASED ON THIS REASONING...HIGH
TEMPERATURES TODAY WILL LIKELY RISE TO AROUND 90 FOR ALL BUT THE
HIGHER TERRAIN LOCATIONS...WITH WIDESPREAD HIGHS IN THE LOWER/MID 90S
SATURDAY AND SUNDAY. FORTUNATELY...DEEP BOUNDARY LAYER MIXING IS
EXPECTED ON SATURDAY AND SHOULD PREVENT SIGNIFICANT CONCERNS FOR HIGH
HEAT INDEX VALUES.

LITTLE CHANGE IN THIS PATTERN IS ANTICIPATED UNTIL SATURDAY NIGHT...
WHEN A POWERFUL MID-LATITUDE TROUGH WILL DIG SOUTHEASTWARD INTO THE
NORTHERN PLAINS/UPPER MISSISSIPPI VALLEY -- FORCING THE SUBTROPICAL
RIDGE TO RETROGRADE WESTWARD INTO THE SOUTHERN ROCKIES. SEVERAL OF
THE GLOBAL MODELS SUGGEST AT LEAST A GLANCING IMPACT FROM A WELL-
DEFINED VORTICITY MAX...WHICH IS PROGGED TO BE ROUNDING THE NORTHERN
PERIPHERY OF THE RIDGE AND MOVING EASTWARD ACROSS KANSAS/MISSOURI ON
SATURDAY. THIS FEATURE OR ITS REMNANTS MAY SHIFT SOUTHEASTWARD ACROSS
NORTHERN ALABAMA ON SUNDAY...PERHAPS PROVIDING ENOUGH FORCING FOR
UVM TO ERODE THE CAP -- ESPECIALLY AS AFTERNOON TEMPERATURES RISE
INTO THE LOWER/MID 90S AND LOW-LEVEL DEWPOINTS INCREASE INTO THE
LOWER 70S. THUS...WE HAVE DECIDED TO INCLUDE A 20 POP FOR ISOLATED
CONVECTION SUNDAY AFTERNOON. POINT FORECAST SOUNDINGS FROM THE
NAMBUFR/GFSBUFR/ECMWF INDEED SHOW THE CAPPING INVERSION WEAKENING
AND LIFTING SUNDAY AFTERNOON. IN THE ABSENCE OF CONVECTION...HEAT
INDEX VALUES WILL BE DANGEROUSLY HIGH IN THE 100-105 DEGREE RANGE.

MODELS SUGGEST THAT THE MID-LATITUDE TROUGH OVER THE UPPER
MISSISSIPPI VALLEY AT THE BEGINNING OF THE EXTENDED PERIOD WILL
CONTINUE TO DIG SOUTHEASTWARD OVER THE GREAT LAKES BEFORE ASSUMING A
NEGATIVE TILT OVER THE EASTERN GREAT LAKES REGION BY 00Z TUESDAY. A
STRONG SURFACE COLD FRONT ASSOCIATED WITH THIS FEATURE WILL SHIFT
SOUTHWARD...REACHING SOUTHERN MIDDLE TENNESSEE BY 12Z MONDAY.
THUNDERSTORMS WILL INCREASE FROM LATE SUNDAY NIGHT THROUGH MONDAY AS
THE COLD FRONT PUSHES SOUTHWARD OVER THE LOCAL AREA...WITH FORECAST
SOUNDINGS CONTINUING TO SUGGEST AN ELEVATED THREAT FOR STRONG/SEVERE
STORMS DURING THIS PERIOD. A DRY NORTHWEST FLOW ALOFT WILL PREVAIL

AREA FORECAST DISCUSSION

440 AM CDT FRI JUL 25 2014

.DISCUSSION...
A MODERATELY STRONG NORTHWEST FLOW ALOFT PREVAILS ACROSS THE CENTRAL
TENNESSEE VALLEY THIS MORNING...WITH THE MID-LEVEL TROUGH AXIS NOW
LOCATED TO THE SOUTHEAST OF THE LOCAL AREA. THIS HAS TRANSLATED TO
VERY PLEASANT EARLY MORNING TEMPERATURES/DEWPOINTS FOR LATE
JULY...WITH PATCHY VALLEY FOG LEADING TO VISIBILITY REDUCTIONS
GENERALLY IN THE 3-5 MILE RANGE.

DURING THE PERIOD FROM TODAY THROUGH SATURDAY...MODELS REMAIN
CONSISTENT IN FORECASTING A STRONG SUBTROPICAL RIDGE -- CURRENTLY
CENTERED ACROSS NEW MEXICO AND THE TEXAS PANHANDLE -- TO BUILD
EASTWARD OVER THE CENTRAL PLAINS AND INTO THE LOWER MISSISSIPPI
VALLEY. SUBSTANTIAL HEIGHT RISES ALOFT WILL RESULT IN THE DEVELOPMENT
OF A PRONOUNCED INVERSION IN THE 850-800 MB LAYER...WHICH WILL WORK
IN TANDEM WITH THE DRY AIRMASS IN PLACE TO LIMIT PRECIPITATION
CHANCES TO A SILENT 5 PERCENT. A COUPLE OF WEAK VORTICES DROPPING
SOUTHWARD IN THE NORTHERLY FLOW ALOFT MAY BRING PERIODS OF ENHANCED
HIGH-LEVEL CLOUDS COVER TO THE REGION TODAY/TONIGHT...BUT WE ARE
GENERALLY EXPECTING MOSTLY CLEAR SKIES WITH THE EXCEPTION OF
SCATTERED CUMULUS THIS AFTERNOON. BASED ON THIS REASONING...HIGH
TEMPERATURES TODAY WILL LIKELY RISE TO AROUND 90 FOR ALL BUT THE
HIGHER TERRAIN LOCATIONS...WITH WIDESPREAD HIGHS IN THE LOWER/MID 90S
SATURDAY AND SUNDAY. FORTUNATELY...DEEP BOUNDARY LAYER MIXING IS
EXPECTED ON SATURDAY AND SHOULD PREVENT SIGNIFICANT CONCERNS FOR HIGH
HEAT INDEX VALUES.

LITTLE CHANGE IN THIS PATTERN IS ANTICIPATED UNTIL SATURDAY NIGHT...
WHEN A POWERFUL MID-LATITUDE TROUGH WILL DIG SOUTHEASTWARD INTO THE
NORTHERN PLAINS/UPPER MISSISSIPPI VALLEY -- FORCING THE SUBTROPICAL
RIDGE TO RETROGRADE WESTWARD INTO THE SOUTHERN ROCKIES. SEVERAL OF
THE GLOBAL MODELS SUGGEST AT LEAST A GLANCING IMPACT FROM A WELL-
DEFINED VORTICITY MAX...WHICH IS PROGGED TO BE ROUNDING THE NORTHERN
PERIPHERY OF THE RIDGE AND MOVING EASTWARD ACROSS KANSAS/MISSOURI ON
SATURDAY. THIS FEATURE OR ITS REMNANTS MAY SHIFT SOUTHEASTWARD ACROSS
NORTHERN ALABAMA ON SUNDAY...PERHAPS PROVIDING ENOUGH FORCING FOR
UVM TO ERODE THE CAP -- ESPECIALLY AS AFTERNOON TEMPERATURES RISE
INTO THE LOWER/MID 90S AND LOW-LEVEL DEWPOINTS INCREASE INTO THE
LOWER 70S. THUS...WE HAVE DECIDED TO INCLUDE A 20 POP FOR ISOLATED
CONVECTION SUNDAY AFTERNOON. POINT FORECAST SOUNDINGS FROM THE
NAMBUFR/GFSBUFR/ECMWF INDEED SHOW THE CAPPING INVERSION WEAKENING
AND LIFTING SUNDAY AFTERNOON. IN THE ABSENCE OF CONVECTION...HEAT
INDEX VALUES WILL BE DANGEROUSLY HIGH IN THE 100-105 DEGREE RANGE.

MODELS SUGGEST THAT THE MID-LATITUDE TROUGH OVER THE UPPER
MISSISSIPPI VALLEY AT THE BEGINNING OF THE EXTENDED PERIOD WILL
CONTINUE TO DIG SOUTHEASTWARD OVER THE GREAT LAKES BEFORE ASSUMING A
NEGATIVE TILT OVER THE EASTERN GREAT LAKES REGION BY 00Z TUESDAY. A
STRONG SURFACE COLD FRONT ASSOCIATED WITH THIS FEATURE WILL SHIFT
SOUTHWARD...REACHING SOUTHERN MIDDLE TENNESSEE BY 12Z MONDAY.
THUNDERSTORMS WILL INCREASE FROM LATE SUNDAY NIGHT THROUGH MONDAY AS

SOME LINGERING PARTLY CLOUDY CONDITIONS ARE EXPECTED THROUGH THE
EARLY EVENING HOURS IN MOST LOCATIONS. IN OUR EXTREME SOUTHEASTERN
COUNTIES MOSTLY CLOUDY CONDITIONS MAY STILL OCCUR THROUGH THE EARLY
EVENING HOURS...BEFORE DISSIPATING.

MODEL GUIDANCE IS FORECASTING FOG IN SOME LOCATIONS PRETTY HARD
TONIGHT. SINCE LIGHT WINDS AND CLEARING SKIES ARE EXPECTED...INCLUDED
PATCHY FOG AFTER MIDNIGHT. EVENING OR MIDNIGHT SHIFT MAY HAVE TO
INCREASE FOG COVERAGE OR DENSITY MORE...BUT FOR NOW HOLDING THE
CONSERVATIVE ROUTE IN GRIDS.

ALTHOUGH MUCH DRIER AIR WILL BRIEFLY PUSH INTO THE AREA FROM THE
NORTHWEST OVERNIGHT AND ON FRIDAY...THE VERY STRONG 596 MB UPPER
LEVEL RIDGE OVER THE SOUTHWEST WILL BUILD EASTWARD FRIDAY THROUGH
SUNDAY. MODELS PROG 1000-500 MB THICKNESS VALUES INCREASING TO
AROUND 580 MB BY SATURDAY AND THEN 582 MB BY SUNDAY. THIS WILL
MEAN HOT CONDITIONS WILL BUILD INTO NORTHERN ALABAMA AND SOUTHERN
MIDDLE TENNESSEE...DESPITE A FRONT HAVING JUST PASSED THROUGH AREA
RECENTLY. HIGH TEMPERATURES WERE ADJUST UP SLIGHTLY ON SATURDAY AND
SUNDAY. BELIEVE HIGHS WILL REACH 95 TO 97 DEGREES DURING THAT
TIMEFRAME. SOME GUIDANCE IS SHOWING 98 OR 99 AT KMSL ON SUNDAY. AT
THE SAME TIME...STRONGER SOUTHWEST FLOW WILL ALSO BRING ABUNDANT LOW
LEVEL MOISTURE BACK INTO THE PICTURE BY SATURDAY AND SUNDAY. THIS
WILL SET THE STAGE FOR DANGEROUS HEAT INDEX VALUES IN THE UPPER 90S
AND AROUND 100 DEGREES DURING THAT TIMEFRAME...WITH THE WORST
CONDITIONS EXPECTED ON SUNDAY. HEAT INDEX VALUES ON SUNDAY COULD
APPROACH 105 DEGREES. SO BE PREPARED AND DRINK PLENTY OF FLUIDS OVER

SOME LINGERING PARTLY CLOUDY CONDITIONS ARE EXPECTED THROUGH THE

COUNTIES MOSTLY CLOUDY CONDITIONS MAY STILL OCCUR THROUGH THE EARLY
EVENING HOURS...BEFORE DISSIPATING.

MODEL GUIDANCE IS FORECASTING FOG IN SOME LOCATIONS PRETTY HARD
TONIGHT. SINCE LIGHT WINDS AND CLEARING SKIES ARE EXPECTED...INCLUDED
PATCHY FOG AFTER MIDNIGHT. EVENING OR MIDNIGHT SHIFT MAY HAVE TO
INCREASE FOG COVERAGE OR DENSITY MORE...BUT FOR NOW HOLDING THE
CONSERVATIVE ROUTE IN GRIDS.

RECENTLY. HIGH TEMPERATURES WERE ADJUST UP SLIGHTLY ON SATURDAY AND
SUNDAY. BELIEVE HIGHS WILL REACH 95 TO 97 DEGREES DURING THAT
TIMEFRAME. SOME GUIDANCE IS SHOWING 98 OR 99 AT KMSL ON SUNDAY. AT

THE ANOMALOUS JULY PATTERN CONTINUES, WITH A RELATIVELY WEAK SURFACE
COLD FRONT SITTING JUST NORTH OF THE HUN CWFA AT 08Z. THIS WAS BEING
MARKED BY A CLUSTER OF SHOWERS AND THUNDERSTORMS AROUND MIDNIGHT, BUT
THIS HAS SINCE DISSIPATED DESPITE THE PRESENCE OF A MID-LEVEL
SHORTWAVE. WITH THE DISSIPATION OF THE CONVECTION, THE FOCUS NOW
SHIFTS TO FOG, AS SEVERAL LOCATIONS HAVE SEEN VISIBILITY RAPIDLY DROP
OFF WITH CLEARING. THERE IS LITTLE DRY AIR ADVECTION OCCURRING
IMMEDIATELY BEHIND THE FRONT; LOWER DEWPOINTS ARE STILL SITTING
ROUGHLY ALONG THE TN-KY STATE LINE.

BASED UPON CURRENT OBSERVATIONS AND CLEARING SKIES, AND THE FAIRLY
WIDESPREAD PRECIPITATION YESTERDAY, DENSE FOG SHOULD BECOME AN
INCREASING PROBLEM AS WE APPROACH SUNRISE. SO WE WILL ISSUE A DENSE
FOG ADVISORY, WHICH WILL BE IN EFFECT THROUGH 9 AM.

NEAR-TERM MODELS HAVE HAD A FAIRLY GOOD HANDLE ON THE CONVECTION
SITUATION THIS MORNING, WITH SEVERAL INDICATING THE HUN CWFA GETTING
SPLIT BY WEAKENING/DISSIPATING CONVECTION TO THE NORTH (AS HAPPENED
BETWEEN 12-2AM) AND STORMS THAT RE-FIRE LATER TODAY TO THE SOUTH.
CONSIDERING THE MID/UPPER-LEVEL DRY AIR RAPIDLY PUSHING INTO THE
AREA (PER WATER VAPOR), THIS SCENARIO IS LOOKING MORE AND MORE
REASONABLE. SO FORECAST POPS FOR TODAY WILL EMPHASIZE THE MORNING
HOURS, ANTICIPATING THE ARRIVAL OF DRIER AIR FOR AFTERNOON, AND SKEW
HIGHER TO THE SOUTH AND EAST WHERE MOISTURE WILL LINGER THE LONGEST.
HIGHS TODAY ARE TOUGH, AS ADVECTION IS NOT EXPECTED TO BE COLD AS
MUCH AS DRY; SO MOS CONSENSUS OF UPPER 80S LOOKS GOOD.

THE REST OF THE SHORT TERM SHOULD BE DRY AS DRY MID/UPPER-LEVEL AIR
SETTLES IN OVER THE REGION. NIGHT TIME TEMPERATURES WILL REMAIN BELOW
NORMAL IN LIGHT OF DRIER-THAN-NORMAL DEWPOINTS AND DECENT RADIATIONAL
COOLING, BUT HIGH TEMPERATURES WILL QUICKLY RISE DUE TO GOOD
INSOLATION AND DRY AIR. IN FACT, THE MOS CONSENSUS PUSHES HIGHS INTO
THE MID AND UPPER 90S SATURDAY AS MID-LEVEL RIDGING MAKES A BRIEF
ATTEMPT TO BUILD OVER THE MID-SOUTH. HOWEVER, THE GFS HAS AVERAGED
2-4 DEGREES TOO WARM THIS SUMMER (THE NAM WARM BIAS IS LESS
PRONOUNCED BUT STILL EXISTS) SO THE FORECAST WILL UNDERCUT THE MOS.

THE FLIRTATION WITH THE HEAT AND HUMIDITY WILL BE SHORT-LIVED, AS
ANOTHER ANOMALOUSLY DEEP (3-4 STANDARD DEVIATIONS BELOW NORMAL)
TROUGH IS EXPECTED TO DIG OVER THE EASTERN CONUS SUNDAY-MONDAY, WITH
THE SURFACE FRONT PROGGED TO PASS ACROSS THE HUN CWFA MONDAY MORNING.
THIS WILL MEAN ANOTHER SURGE OF INCREASED RAIN/STORM POTENTIAL,
THOUGH THE OVERNIGHT ARRIVAL MAY LIMIT COVERAGE. THE MESOSCALE SETUP
IS TYPICAL FOR JULY--DECENT INSTABILITY BUT LITTLE SHEAR.

BEHIND THE FRONT, ONCE AGAIN, A DRY FORECAST IS EXPECTED FOR THE
REST OF THE FORECAST PERIOD (THROUGH WEDNESDAY) AS DRIER AIR
ASSOCIATED WITH THE TROUGH SETTLES IN OVER THE AREA. HIGH
TEMPERATURES SHOULD FALL BACK (AGAIN) TO 5-10 DEGREES BELOW NORMAL
WITH LOWS 10-15 DEGREES BELOW NORMAL. THE GFSX MOS SEEMS TOO WARM IN
THIS REGIME, AND HAVE TRENDED TOWARDS A MODIFIED PERSISTENCE BASED ON
SIMILAR PATTERNS FROM EARLIER THIS SUMMER.

/ISSUED 352 AM CDT THU JUL 24 2014/
THE ANOMALOUS JULY PATTERN CONTINUES, WITH A RELATIVELY WEAK SURFACE
COLD FRONT SITTING JUST NORTH OF THE HUN CWFA AT 08Z. THIS WAS BEING
MARKED BY A CLUSTER OF SHOWERS AND THUNDERSTORMS AROUND MIDNIGHT, BUT
THIS HAS SINCE DISSIPATED DESPITE THE PRESENCE OF A MID-LEVEL
SHORTWAVE. WITH THE DISSIPATION OF THE CONVECTION, THE FOCUS NOW
SHIFTS TO FOG, AS SEVERAL LOCATIONS HAVE SEEN VISIBILITY RAPIDLY DROP
OFF WITH CLEARING. THERE IS LITTLE DRY AIR ADVECTION OCCURRING
IMMEDIATELY BEHIND THE FRONT; LOWER DEWPOINTS ARE STILL SITTING
ROUGHLY ALONG THE TN-KY STATE LINE.

BASED UPON CURRENT OBSERVATIONS AND CLEARING SKIES, AND THE FAIRLY
WIDESPREAD PRECIPITATION YESTERDAY, DENSE FOG SHOULD BECOME AN
INCREASING PROBLEM AS WE APPROACH SUNRISE. SO WE WILL ISSUE A DENSE
FOG ADVISORY, WHICH WILL BE IN EFFECT THROUGH 9 AM.

NEAR-TERM MODELS HAVE HAD A FAIRLY GOOD HANDLE ON THE CONVECTION
SITUATION THIS MORNING, WITH SEVERAL INDICATING THE HUN CWFA GETTING
SPLIT BY WEAKENING/DISSIPATING CONVECTION TO THE NORTH (AS HAPPENED
BETWEEN 12-2AM) AND STORMS THAT RE-FIRE LATER TODAY TO THE SOUTH.
CONSIDERING THE MID/UPPER-LEVEL DRY AIR RAPIDLY PUSHING INTO THE
AREA (PER WATER VAPOR), THIS SCENARIO IS LOOKING MORE AND MORE
REASONABLE. SO FORECAST POPS FOR TODAY WILL EMPHASIZE THE MORNING
HOURS, ANTICIPATING THE ARRIVAL OF DRIER AIR FOR AFTERNOON, AND SKEW
HIGHER TO THE SOUTH AND EAST WHERE MOISTURE WILL LINGER THE LONGEST.
HIGHS TODAY ARE TOUGH, AS ADVECTION IS NOT EXPECTED TO BE COLD AS
MUCH AS DRY; SO MOS CONSENSUS OF UPPER 80S LOOKS GOOD.

THE REST OF THE SHORT TERM SHOULD BE DRY AS DRY MID/UPPER-LEVEL AIR
SETTLES IN OVER THE REGION. NIGHT TIME TEMPERATURES WILL REMAIN BELOW
NORMAL IN LIGHT OF DRIER-THAN-NORMAL DEWPOINTS AND DECENT RADIATIONAL
COOLING, BUT HIGH TEMPERATURES WILL QUICKLY RISE DUE TO GOOD
INSOLATION AND DRY AIR. IN FACT, THE MOS CONSENSUS PUSHES HIGHS INTO
THE MID AND UPPER 90S SATURDAY AS MID-LEVEL RIDGING MAKES A BRIEF
ATTEMPT TO BUILD OVER THE MID-SOUTH. HOWEVER, THE GFS HAS AVERAGED
2-4 DEGREES TOO WARM THIS SUMMER (THE NAM WARM BIAS IS LESS
PRONOUNCED BUT STILL EXISTS) SO THE FORECAST WILL UNDERCUT THE MOS.

THE FLIRTATION WITH THE HEAT AND HUMIDITY WILL BE SHORT-LIVED, AS
ANOTHER ANOMALOUSLY DEEP (3-4 STANDARD DEVIATIONS BELOW NORMAL)
TROUGH IS EXPECTED TO DIG OVER THE EASTERN CONUS SUNDAY-MONDAY, WITH

403 PM CDT WED JUL 23 2014

.DISCUSSION...
A BROKEN LINE OF SHOWERS AND THUNDERSTORMS CONTINUE TO SLOWLY PUSH
SOUTH THROUGH CULLMAN...MARSHALL...AND DEKALB COUNTIES. ADDITIONAL
SCATTERED STRONG AND MARGINALLY SEVERE STORMS CONTINUE TO DEVELOP
OVER LAUDERDALE COUNTY AT THIS TIME AS WELL. IN BETWEEN ACTIVITY HAS
MOSTLY DISSIPATED AS THE ATMOSPHERE HAS BEEN WORKED OVER BY EARLIER
CONVECTION.

THIS ACTIVITY HAS FORMED ALONG A PREFONTAL TROUGH AXIS AHEAD OF THE
MAIN COLD FRONT WHICH CURRENTLY STRETCHES FROM SOUTHERN OHIO
SOUTHWEST INTO NORTHERN MISSOURI. EXPECT SCATTERED TO LIKELY SHOWERS
AND STORMS TO CONTINUE THIS EVENING...WITH LIKELY COVERAGE OVER
EXTREME NW ALABAMA.

RUC13 HAS HAD A GOOD HANDLE ON CONVECTION SO FAR. MODELS ALL SHOW THE
MAIN COLD FRONT APPROACHING SOUTHERN MIDDLE TENNESSEE AROUND
MIDNIGHT. BOTH GFS40 AND RUC13 SHOW A MORE CONCENTRATED AREA OF
SHOWERS AND THUNDERSTORMS REDEVELOPING AHEAD OF THIS FRONT BETWEEN 2
AM AND 7 AM...ALTHOUGH GFS40 DISSIPATES THIS ACTIVITY QUICKLY TOWARDS
DAYBREAK. RUC13 LOOKS MORE REASONABLE AND KEEPS THIS ACTIVITY GOING
WHILE SHIFTING IT SOUTHWARD TOWARD THE TENNESSEE RIVER DURING THE
MORNING HOURS ON THURSDAY. PWATS REMAIN BETWEEN 1.5 AND 1.8 INCHES
OVERNIGHT INTO TUESDAY MORNING AHEAD OF THE FRONT AND WITH CAPE
VALUES ALOFT REMAINING AROUND 1000 J/KG...THUS THE RUC13 POPS SEEM
MORE REASONABLE. LOCALLY HEAVY RAINFALL CAUSING SOME FLASH FLOODING
IS POSSIBLE...ESPECIALLY WITH WEAK FLOW EXPECTED UPSTREAM OF THE
FRONT AND POSSIBLE TRAINING OF STORMS.

DRIER AIR WILL PUSH INTO THE AREA FROM THE NORTHWEST TUESDAY
MORNING. THUS TAPERED POPS DOWN FROM SOUTHEAST TO NORTHWEST DURING
THE AFTERNOON HOURS...TAKING OUT POPS ENTIRELY FOR EXTREME NW
ALABAMA. KEPT A 60 POP MAINLY SOUTH OF THE TENNESSEE RIVER THURSDAY
MORNING INTO THE AFTERNOON HOURS...WITH LOWER ISOLATED TO SCATTERED
POP TO THE NORTHWEST. LOCALLY HEAVY RAINFALL CAUSING FLASH FLOODING
WILL REMAIN POSSIBLE THROUGH THE DAY ON THURSDAY...MAINLY SOUTH OF
THE TENNESSEE RIVER. CLOUDS AND PRECIPITATION SHOULD MAKE FOR A COOL
DAY ON THURSDAY WITH HIGHS ONLY CLIMBING INTO THE LOWER TO MID 80S.

EXPECT SHOWERS AND STORMS TO END BY LATE THURSDAY AFTERNOON...AS THE
FRONT SHIFTS SOUTH OF THE CULLMAN COUNTY. A FEW CLOUDS COULD LINGER
INTO THURSDAY NIGHT.

DESPITE THE FRONTAL PASSAGE...COOLER AIR DOES NOT PUSH INTO THE AREA
BEHIND THE FRONT. DRIER AIR WILL...BUT AN UPPER RIDGE BEHIND THE
FRONT SHOULD RAISE HIGH TEMPERATURES BACK INTO THE LOWER 90S QUICKLY
ON FRIDAY. MODELS CONTINUE TO BUILD THIS RIDGE IN FROM THE WEST
THROUGH SUNDAY...BEFORE ANOTHER COLD FRONT APPROACHES THE AREA
SATURDAY NIGHT INTO SUNDAY. SHOWER AND THUNDERSTORM CHANCES INCREASE
AHEAD OF THIS SYSTEM AGAIN SUNDAY NIGHT INTO MONDAY. STRONGER SHEAR
CONTINUES TO BE SHOWN BY MODELS AND THIS WILL LIKELY INCREASE THE
POSSIBILITY OF STRONGER TO SEVERE STORMS DEVELOPING.

VERY COOL AIR COULD MOVE INTO THE AREA BEHIND THIS SYSTEM EARLY NEXT
WEAK. LOWERED HIGH TEMPERATURES MONDAY AND TUESDAY TO REFLECT THIS.

.AVIATION...
/ISSUED 1247 PM CDT WED JUL 23 2014/
FOR 18Z TAFS...COMBINATION OF WEAK SFC BOUNDARY AND UPPER LEVEL
TROUGH WILL MAINTAIN UNSETTLED WEATHER ACROSS THE REGION OVER THE

WITH VICINITY SHOWERS THROUGH THE PERIOD TO ACCOUNT FOR UNCERTAINTY.
ALSO KEPT A WINDOW OF THUNDERSTORM POTENTIONAL WITH MVFR VSBYS
THROUGH MID AFTN AT KHSV BASED ON CURRENT RADAR AND MESOSCALE TRENDS.
MODEL GUIDANCE INDICATES A HIGH PROBABILITY OF CONVECTION LATE
TONIGHT/EARLY THURSDAY AND INCLUDED A WINDOW OF MVFR CONDITIONS DUE
TO THUNDERSTORMS DURING THAT PERIOD. OVERALL WIND FIELD SHOULD BE
LIGHT ASIDE FROM BRIEFLY TURBULENT WITHIN/NEAR THUNDERSTORMS.
