AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 303 PM EDT WED JUL 11 2012 .SYNOPSIS... A WEAK COOL FRONT WILL SLOWLY SAG SOUTH OF THE REGION WHILE WEAK BUT MOIST HIGH PRESSURE NOSES IN OVER THE NEXT SEVERAL DAYS. BERMUDA HIGH PRESSURE WILL BUILD INTO THE REGION LATER THIS WEEKEND AND LINGER THROUGH NEXT WEEK. && .NEAR TERM /THROUGH THURSDAY/... WEATHER AND PATTERN MUCH DIFFERENT THAN TUESDAY. WIDESPREAD SHRA ACROSS THE MTNS AND FOOTHILLS WITH SCT SHRA DEVELOPING ELSEWHERE. ONLY ISOLATED TSRA OCCURRING ATTM. INSTABILITY MUCH LOWER THAN PREVIOUS DAYS WITH CLOUDS AND PRECIP KEEPING TEMPS DOWN. THIS IS IN ADDITION TO THE SFC BOUNDARY MOVING TO OUR SOUTH BRINGING IN A SLIGHTLY COOLER AIRMASS OVERALL. BEST INSTABILITY AND DCAPE VALUES ARE CURRENTLY ACROSS NE GA AND THE WRN UPSTATE WHERE LESS PRECIP HAS FALLEN AND MORE SUNSHINE HAS OCCURRED. ALTHOUGH WIDESPREAD SHRA WILL CONTINUE OVER THE MTNS AND DEVELOP ELSEWHERE THRU THE AFTERNOON AND CONTINUE INTO THE EVENING...TSRA COVERAGE WILL REMAIN ON THE LOW SIDE. BEST CHC FOR TSRA WILL BE OUTSIDE OF THE MTNS WITH BEST CHC OF SVR ACROSS NE GA AND THE UPSTATE. EXPECT ONLY ISOLATED SVR ATTM. HAVE BEEN WATCHING THE MTNS REGARDING FLOOD POTENTIAL. THE ATMOS THERE IS VERY MOIST WITH HIGH PW. THERE HAS BEEN SOME ISOLATED OFF AND ON HEAVY RAIN OVER THIS AREA. HOWEVER...QPF VALUES HAVE GENERALLY BEEN MODERATE AT BEST. THERE IS MORE SYNOPTIC SCALE FORCING THIS AFTERNOON WITH SHORT WAVE MOVING IN AND DIVERGENCE FROM THE RIGHT ENTRANCE REGION OF THE UPPER JET. THESE FEATURES WEAKEN OVERNIGHT AND SHIFT WEST AND NORTH OF THE AREA. THE MOISTURE WILL REMAIN HIGH ALONG WITH GOOD LOW LEVEL FORCING AS H925 TO H85 VEER TO E AND SE. HOWEVER...WITH THE LACK OF INSTABILITY AND WANING QG FORCING...THE THREAT OF PROLONGED HEAVY RAIN HAS DIMINISHED. IN FACT...HPC HAS BACKED OFF SIGNIFICANTLY ON THE QPF GUIDANCE FOR OUR AREA AND MOVED IT WEST TO THE BETTER FORCING. THEREFORE...WILL NOT ISSUE A WATCH FOR THE MTNS...BUT WILL KEEP AN EYE ON ANY ISOLATED FLOOD PROBLEMS. SHUD BE ANOTHER DAY OF DEVELOPING WIDESPREAD SHRA AND ISOLATED TO SCT TSRA THU. LOW LEVEL FLOW REMAINS CONDUCIVE FOR RAIN...BUT THE SYNOPTIC SCALE AND QG FORCING REMAIN BETTER TO OUR NORTH AND WEST. THEREFORE...DO NOT EXPECT ANY SIGNIFICANT HEAVY RAINFALL AREAS. INSTABILITY AND DCAPE REMAIN LIMITED THU...BUT CANNOT RULE OUT AN ISOLATED SVR STORM DURING THE AFTERNOON. CLOUDS AND PRECIP WILL KEEP HIGHS BELOW NORMAL ONCE AGAIN. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/... AS OF 230 PM WEDNESDAY...AN UPPER RIDGE BUILDS BACK WESTWARD FROM THE NORTH ATLANTIC DURING THE SHORT TERM...INCREASING HEIGHTS ACRS THE SOUTHEAST CONUS. THE SFC HIGH WILL BE CENTERED NORTH OF THE USUAL BERMUDA HIGH SETUP...KEEPING LLVL FLOW OUT OF THE SOUTHEAST. FCST SNDGS SHOW VERY MOIST PROFILES CONTINUE INTO FRIDAY NIGHT...BUT SOME MID LVL DRYING OCCURS INTO SATURDAY. MODELS IN GOOD AGREEMENT ON PLENTY OF STRATUS LINGERING WITHIN THE SELY UPSLOPE FLOW ON FRIDAY...WITH SOME BREAKING UP OF CLOUDS FROM SOUTHEAST TO NORTHWEST DURING THE DAY. SBCAPE GENERALLY ONLY 1000-1500 J/KG WITH LOW DCAPE. SO HIGH POPS CONTINUE WITH LOW SVR THREAT. ON SATURDAY...MORE MIXING AND CLEARING OF CLOUDS EXPECTED...ALLOWING FOR MORE INSOLATION...WARMER MAX TEMPS AND HIGHER DCAPE. SBCAPE IS PROGGED TO BE A LITTLE HIGHER ON SATURDAY...BUT RIDGING ALOFT MAY LIMIT COVERAGE SOMEWHAT. SO CONVECTION MAY BE MORE SCATTERED IN NATURE...WITH MORE CELLS HAVING POTENTIAL TO PRODUCE LARGE HAIL AND DAMAGING WINDS. QPF DOES NOT LOOK TO BE HEAVY AS UPPER FORCING BECOMES NEUTRAL. BUT LOCALLY HEAVY RAIN IS STILL EXPECTED...ESP ALONG BLUE RIDGE WITH PERSISTENT SELY FLOW. MAX TEMPS STILL A COUPLE CATEGORIES BELOW NORMAL FRIDAY...THEN SHUD BE A CATEGORY OR TWO WARMER ON SATURDAY...ASSUMING STRATUS SCATTERS OUT. MIN TEMPS BOTH NIGHTS NEAR OR SLIGHTLY ABOVE NORMAL UNDER STRATUS. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... AT 1230 PM TUESDAY...THE CLIMB BACK TO NORMAL MID-JULY TEMPERATURES WILL CONTINUE ON SUNDAY AS BERMUDA HIPRES REESTABLISHES ITSELF. MODEL RESPONSE REMAINS ROBUST ENUF TO CONTINUE TO ADVERTISE SOLID MAINLY DIURNAL DEEP CONVECTIVE CHANCES. THERE LOOKS TO BE NOMINAL CHANGE IN THE WEAK PRESSURE PATTERN ATOP THE SE CONUS THROUGH MONDAY AND A TYPICAL MID-SUMMER DAY IS EXPECTED...SEASONABLY WARM AND HUMID WITH SMALL AND/OR SLIGHT DIURNAL TSTM POSSIBILITIES. A PERSISTENCE FCST WILL BE FEATURED FOR TUESDAY. THE LATEST ECMWF IS HINTING AT AN OHIO VALLEY WEAKNESS DEVELOPING ON DAY 7 WHICH MAY ALLOW FOR MORE MOISTURE TO HEAD UP OUR WAY BY THE END OF THE PERIOD BUT AT THIS POINT FOR NEXT THURSDAY...PRETTY MUCH A CLIMO FCST IS ANTICIPATED. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... AT KCLT AND ELSEWHERE...A DIFFICULT SITUATION FOR AVIATION CONCERNS CONTINUES THIS TAF PERIOD. COPIOUS MOISTURE AND NON STOP WEAK FORCING WILL RESULT IN CONTINUED NUMEROUS TO WIDESPREAD SHOWERS AND SCT TO NUMEROUS THUNDERSTORMS ACROSS THE AREA THIS AFTERNOON AND EVENING. FOLLOWING THE NEW TAF TS RULES...HAVE QUITE A BIT OF TS MENTIONED THRU THE PERIOD. LOW VFR WITH TEMPO VFR THE MAIN IMMEDIATE CONCERN OUTSIDE OF THE MTNS...WITH PRECIP ON THE DOOR STEP AT KAVL. HAVE TAKEN CURRENT CONDITIONS INTO EFFECT...AND HAVE MVFR EARLY THIS AFTERNOON THEN VFR THE REST OF THE AFTERNOON AND EARLY EVENING. MAIN RESTRICTION THREAT WILL BE CONVECTIVE CELLS THRU EVENING... AMENDMENTS AS CELLS APPROACH AIR FIELDS. OVERNIGHT...COPIOUS LOW LEVEL MOISTURE AND ELY TO SLY FLOW WILL LEAD TO MVFR THEN IFR CIGS WITH GENERALLY MVFR VSBY...IFR AT KAVL. SHRA WITH ISOLATED TSRA WILL CONTINUE AS WELL. EXPECT ONLY SLOW IMPROVEMENT TO MVFR CIGS AND GENERALLY VFR VSBY BY MID MORNING. MVFR CIGS LIKELY TO CONTINUE TO THE END OF THE PERIOD. WIDESPREAD SHRA WITH DEVELOPING TSRA LIKELY AGAIN THURSDAY. OUTLOOK...WIDESPREAD SHRA/TSTMS WILL CONTINUE THROUGH THE END OF THE WEEK. A MOIST AIRMASS WILL SUPPORT RESTRICTIONS IN LATE NIGHT AND EARLY MORNING FOG AND STRATUS. MORE SUMMER-LIKE CONDITIONS WILL RETURN FOR THE WEEKEND WITH WARMER TEMPERATURES...LESS CONVECTION AND LESS IN THE WAY OF MORNING RESTRICTIONS.
