AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 236 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/... AS UPPER TROF DIGS OFF E COAST AND RIDGE AXIS RETREATS TO CENTRAL PLAINS...EXPECT H5 DIFLUENT 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. CONVECITON 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 DIFLUENT 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 /19Z 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.
