Area forecast discussion, Jul 31, 5:30 PM EDT, 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
530 PM EDT SUN JUL 31 2011

.SYNOPSIS...
A WEAK COLD FRONT WILL SLOWLY PUSH SOUTH ACROSS THE REGION...THEN
GRADUALLY DISSIPATE ACROSS SOUTH GEORGIA AND THE CAROLINA COAST ON
MONDAY. STRONG HIGH PRESSURE WILL BUILD OVER THE AREA TUESDAY AND
WEDNESDAY. ANOTHER WEAK COLD FRONT WILL APPROACH THE SOUTHERN
APPALACHIAN REGION LATE NEXT WEEK.

&&

.NEAR TERM /THROUGH MONDAY/...
ROBUST POP TO BE CARRY INTO EARLY EVENING ALONG AND SE OF CONVECTIVE
LINE ACRS THE PIEDMONT AND SOUTH OF ENCROACHING NORTHERN CWFA
OUTFLOW...WITH A SHOTGUN LOW OR SLIGHT CHANCE ELSEWHERE.

AS UPPER TROF DIGS OFF E COAST AND RIDGE AXIS RETREATS TO CENTRAL
PLAINS...EXPECT H5 DIFFLUENT FLOW OVER THE AREA THRU THIS EVE. WITH
CAPE VALUES NEAR 1000 J/KG...SFC DEW POINTS IN THE 70S...INCREASED
MOISTURE THRU THE COLUMN AND PWATS OVER 2 INCHES...EXPECT NUMEROUS
SHWRS AND TSTMS ACROSS THE CWA THRU THIS EVE. THERE IS A CHC OF
ISOLD STRONG WIND GUSTS BUT WITHOUT DRY MID LEVEL AIR THE MAIN
CONCERN WILL BE PERIODS OF HVY RAIN W/TSTMS...ESP IN AREAS THAT
PICKED UP 1-2IN OF RAIN YDA. CONVECTION WILL TAPER OFF LATE THIS EVE
AND SHOULD DIE OUT OVERNIGHT...EXCEPT A FEW LINGERING SHWRS WILL BE
PSBL IN THE S CWA. MRNG LOWS WILL COOL TO WITHIN A DEG OR TWO OF
AVG. SFC BOUNDARY PUSHES WELL S OF CWA MON WHILE NW DIFFLUENT FLOW
ALOFT CONTINUES SO WE HELD ON TO SLIGHT CHC POPS ACROSS FAR S CWA
THRU EARLY AFTN. TEMPS WILL BE COOLER BUT STILL A COUPLE DEG ABOVE
AVG.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
AS OF 130 PM SUNDAY...A RATHER STRAIGHTFORWARD SHORT TERM FORECAST
IS IN THE OFFING. THE RETURN OF STRONG UPPER RIDGING AND SUBSIDENCE
WILL ENGULF THE AREA TUE AND PERSIST THROUGHOUT WED. THE OP MODELS
DISAGREE WITH THE DEGREE OF DOWNWARD FORCING AND MLVL MOISTURE
SOMEWHAT...WITH THE 12Z GFS ADDING MORE ACU THAN THE OTHER
MODELS...HOWEVER THIS WILL HAVE LITTLE IMPACT ON THE SENSIBLE WX TO
BE EXPECTED. MODEL CROSS SECTIONS SHOW TWO DISTINCT PERIODS OF
SUBSIDENCE...THE SECOND REINFORCING THE FIRST ON WED. WITH THIS IN
MIND...AND A NEBULOUS DRY SFC FLOW...MAX TEMPS SHOULD RESPOND INTO
THE U90S NON/MTNS AND L90S MTN VALLEYS TUE...AND A COUPLE DEGREES
HOTTER ON WED. A GOOD MIXING OF DRY AIR TO THE SFC WILL ALLEVIATE ANY
HEAT INDEX CONCERNS BOTH DAYS...BUT AMBIENT TEMPS WILL CREATE THE
USUAL INCREASED HEAT ISSUES...SUCH AS ENCLOSED SPACES AND PERSONAL
HYDRATION. A S/W ROUNDING THE RIDGE WILL MAKE A RUN FOR THE CWFA
LATE WED AND IT/S MOISTURE LEVELS WILL BE ENTRAINED WITH THE
PREVAILING DRY AIR...HOWEVER ISOLATED -SHRA/TSTMS ARE POSSIBLE ACROSS
THE NRN NC MTNS WED EVENING AS THIS SYSTEM NEARS.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AS OF 1210 PM SUNDAY...THE GLOBAL MODELS ARE IN GOOD AGREEMENT THAT
THE SUBTROPICAL RIDGE WILL REMAIN MORE OR LESS PARKED OVER THE
SOUTHERN PLAINS THROUGH THE MEDIUM RANGE....RESULTING IN PERSISTENT
N/NW FLOW OVER MUCH OF THE SOUTHEAST/MID-ATLANTIC. ALTHOUGH THE
MODELS ARE ALSO IN AGREEMENT THAT A WEAK FRONTAL BOUNDARY WILL SAG
INTO THE REGION BY THURSDAY...NONE ARE PARTICULARLY BULLISH ON
CONVECTIVE PRECIP THU AFTERNOON. THIS ISNT TOO SURPRISING...
CONSIDERING THAT W AND NW LOW LEVEL FLOW IN ADVANCE OF THE FRONT
PROBABLY DICTATES THAT THERE WILL NOT BE A GREAT DEAL OF MOISTURE IN
PLACE. NEVERTHELESS...ITS RARE TO SEE A SURFACE BOUNDARY MOVE OVER
THE AREA THIS TIME OF THE YEAR WITHOUT AT LEAST SCATTERED DIURNAL
CONVECTION....SO CHANCE POPS WILL BE RETAINED ACROSS MOST OF THE
AREA DURING THIS TIME. IN FACT...AT LEAST SLIGHT CHANCE DIURNAL POPS
WILL LINGER INTO NEXT WEEKEND...AS THE MODELS ARE HINTING AT ANOTHER
FRONTAL BOUNDARY DROPPING INTO THE AREA LATE IN THE PERIOD. TEMPS
WILL GENERALLY REMAIN ABOVE NORMAL...ALTHOUGH SLIGHTLY COOLER
THICKNESS VALUES MAY YIELD MAXES A LITTLE CLOSER TO CLIMO FRI AND
SAT.

&&

.AVIATION /22Z SUNDAY THROUGH FRIDAY/...
AT KCLT AND ELSEWHERE...EXPECT SCT-NUMEROUS SHWRS/TSTMS THIS
AFTN-EVE. EXPECT TEMPO GROUPS FOR ALL TERMINALS AT SOME TIME THRU
THIS EVE FOR VRB WINDS...TSRA...LOW CIGS AND LOW VSBY. TOWARD
MIDNIGHT CONVECTION SHOULD DIMINISH...THEN LOOK FOR AREAS OF FOG
LATE TONIGHT...PREDOMINANTLY MVFR...BECMG IFR AT KAVL. AFTER EARLY
MRNG FOG LOW CLOUD CIGS LINGER THRU THE MRNG...PSBLY MVFR BUT KEPT
THAT LAYER SCT ATTM.

OUTLOOK...SFC BOUNDARY WILL PUSH S OF THE AREA MONDAY  WITH DRIER
CONDITIONS EXPECTED THRU MID WEEK...THEN INCRSNG AFTN CONVECTION AND
MRNG FOG.
