AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 218 PM EDT TUE JUL 31 2012 .SYNOPSIS... WEAK HIGH PRESSURE WILL BUILD OVER THE REGION TONIGHT AND LINGER THROUGH THE WEEKEND. A COLD FRONT IS EXPECTED TO MOVE ACROSS THE REGION ON MONDAY FOLLOWED BY ANOTHER HIGH PRESSURE BUILDING IN FROM THE NORTH ON TUESDAY. && .NEAR TERM /THROUGH WEDNESDAY/... WATER VAPOR IMAGERY SHOWS STRONGEST VORT LOBE PUSHING INTO THE NW MTNS WITH BEST FORCING AHEAD OF IT...KICKING OFF WIDESPREAD SHWRS AND ISOLD TSTMS...ESP ACROSS THE FOOTHILLS AND PIEDMONT. WITH OVERCAST SKIES...SHWRS AND COOLER AIR ACROSS THE CWA...THE LATE AFTN TEMP FCST WAS SCALED BACK. CAPE VALUES HAVE REMAINED QUITE LOW ALSO SO HAVE LIMITED TS MENTION TO THE CHC RANGE. AREAS OF HEAVY RAIN IN WHAT APPEARS TO BE A VERY LOW-TOPPED MCS SHOULD CONTINUE TO CAUSE ISOLD LOW-END FLOODING ISSUES UNTIL THE SYSTEM MOVES E OF THE AREA LATER TODAY...AND RAINFALL RATES AROUND CLT WILL HAVE TO BE WATCHED. CONVECTION WILL TAPER OFF THIS EVE BUT ISOLD SHWRS ARE EXPECTED TO LINGER LATE TONIGHT...ESP OVER THE SE CWA. MRNG LOWS WILL BE NEAR TO SLIGHTLY BELOW AVG AND AREAS OF FOG ARE LIKELY...ESP NEAR LAKES AND RIVERS. THE SHORTWAVE TRACKS WELL E WED BUT ANOTHER WEAK IMPULSE WILL DROP DOWN OVER THE REGION IN CONTINUING NW FLOW ALOFT. WITH MOISTURE PROFILES BEING MORE SHALLOW...AND LESS UPPER FORCING... HAVE CHC POPS ACROSS MOST OF THE CWA THU AFTN. HIGHS WILL BE NEAR AVG. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... AS OF 2 PM EDT TUE...RATHER PERSISTENT E COAST TROUGHING WILL REMAIN IN PLACE THROUGH THU...WITH HEIGHTS FORECAST TO SLOWLY RISE ON FRI. POORLY RESOLVED WEAK SHORT WAVES IN THE MODELS MAKE IT DIFFICULT TO DISPLAY TOO MUCH CONFIDENCE IN ANY ONE FEATURE. BOTH THE GFS AND NAM DO SHOW SOME MODEL RESPONSE EARLY WED NIGHT OVER THE PIEDMONT AS AN APPARENT SHORT WAVE MOVES BY AND A WEAKENING BOUNDARY PROVIDES SOME LOW LEVEL CONVERGENCE. THEREFORE...WILL HAVE SOME SCATTERED TYPE POPS IN THAT AREA DURING THE EVENING HOURS. DRYER AIR ARRIVES BY LATE WED NIGHT AS WEAK HIGH PRESSURE BUILDS IN FROM THE NW. THURSDAY SHOULD FEATURE CONSIDERABLE SUNSHINE AND HOT AFTERNOON TEMPS. MODEL SOUNDINGS IN BUFKIT SHOW CONSIDERABLE INSTABILTY BY LATE THU AFTERNOON AND SOME MODEL QPF RESPONSE DURING THE EVENING OVER THE PIEDMONT IN THE WEAKLY CONVERGENT FLOW. HENCE...WILL ADD SOME WIDELY SCATTERED TYPE POPS FOR THAT TIMEFRAME...BUT ENDING ANY CONVECTIVE THREAT BY MIDNIGHT. ON FRIDAY...ANOTHER WEAK SHORT WAVE DURING THE AFTERNOON HAS THE POTENTIAL TO TRIGGER MORE WIDESPREAD CONVECTION SO WILL HAVE SOLID SCATTERED POPS FOR THAT. LEANED TOWARD THE BIAS CORRECTED GMOS FOR MAX/MIN TEMPS AS IT HAS BEEN PERFORMING VERY WELL. TEMPS THROUGH THE SHORT TERM WILL BE A CATEGORY OR SO ABOVE AVERAGE. && .LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... AS OF 115 PM EDT TUESDAY...THE UPPER PATTERN WILL TRANSITION OVER THE WEEKEND FROM A MEAN TROUGH OVER THE SE U.S. TO A FLAT RIDGE. THEREFORE...THE ACTIVE NORTHERN STREAM WAVES WILL REMAIN NORTH OF THE AREA. THIS PATTERN FAVORS TYPICAL SUMMERTIME SENSIBLE WEATHER. THEREFORE...WE A EXPECT A STRONG DIURNAL PATTERN TO THE DAILY CONVECTION. HOWEVER WITH WEAKLY UPSLOPE FLOW...SOME NOCTURNAL SHOWERS ARE NOT OUT OF THE QUESTION OVER THE MOUNTAINS. TEMPERATURES ARE EXPECTED TO REMAIN ABOUT A CATEGORY ABOVE AVERAGE SAT AND SUN. A MODEL CONSENSUS INDICATES THAT A VIGOUROUS WAVE WILL MOVE ACROSS THE GREAT LAKES SUN THROUGH MON WHICH WILL CAUSE HEIGHTS TO GRADUALLY FALL AGAIN ACROSS THE SE. A SHORTWAVE IS EXPECTED TO CROSS THE AREA ON MON WHILE AT THE SURFACE A COLD FRONT WILL APPROACH FROM THE NW LATE IN THE DAY AND MOVE INTO THE AREA ON MON NIGHT. HPC KEEPS THE FRONT NORTH OF THE AREA INTO TUE...BUT ECM TAKES THE BOUNDARY SOUTH OF THE FORECAST AREA ON TUE WITH THE GFS LAYING THE FRONT OVER THE AREA. THESE TRIGGERING MECHANISMS SUPPORT MORE SOLID POPS IN THE FORECAST FOR MON INTO TUE. MAX TEMPS WILL CONTINUE ABOVE AVERAGE WITH 80S MTNS AND LOWER 90S PIEDMONT. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... AT KCLT...AS SHORTWAVE AND ASSOC AREA OF CONVECTION MOVES IN EXPECT AT LEAST TEMPO MVFR CIG WITH PERIODS OF IFR EXPECTED IN HEAVIER SHWRS. SCT TS ALSO PSBL WITH A TEMPO TS 18-22Z.
