Area forecast discussion, Jun 7, 3:07 PM EDT, 9 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 307 PM EDT SAT JUN 7 2008 .SYNOPSIS... UPPER LEVEL HIGH PRESSURE WILL CONTINUE ACROSS THE AREA THROUGH THE WEEKEND...THEN WEAKEN DURING THE MIDDLE OF NEXT WEEK. THIS WILL RESULT IN TEMPERATURES WELL ABOVE NORMAL FOR THIS TIME OF YEAR CONTINUING INTO EARLY NEXT WEEK. && .NEAR TERM /THROUGH SUNDAY/... LOW LEVEL CONVERGENCE SHOULD MAXIMIZE ACROSS THE NC MOUNTAINS BETWEEN 21Z AND 00Z. ISOLATED CELLS HAVE BEEN TRIGGERING NEAR THE TN BORDER THROUGHOUT THE AFTERNOON...AND COVERAGE SHOULD EXPAND INTO EARLY EVENING BEFORE STEADILY WANING THROUGH MIDNIGHT WITH THE LOSS OF DAYTIME HEATING. WILL RETAIN MOUNTAIN ISOLATED TO SCATTERED COVERAGE INTO THE EVENING HOURS...WITH ISOLATED DEVELOPMENT EXTENDING OUT INTO THE NC FOOTHILLS THROUGH LATE EVENING. LAPS INSTABILITY IS QUITE IMPRESSIVE ACROSS THE MTNS...WITH SFC BASED CAPE VALUES 2000 TO 3000 J/KG...BUT VERY WARM PROFILES SHOULD GREATLY LIMIT ANY HAIL POTENTIAL. DOWNDRAFT CAPE VALUES IN EXCESS OF 1000 J/KG...ALONG WITH LINGERING MID LEVEL DRY AIR UNDER THE RIDGE...WILL SLIGHTLY INCREASE THE DOWNBURST POTENTIAL. WILL CONTINUE TO FEATURE MIN TEMPS ON THE WARM SIDE OF MOS OVERNIGHT. HIGHS LOOK TO BE ANOTHER DEGREE OR SO WARMER TOMORROW THAN TODAY...AND HEAT INDEX VALUES MAY REACH 102 TO 104 IN THE PIEDMONT. HOWEVER...ANOTHER AFTERNOON OF SLIGHT DEWPOINT MIXOUT SHOULD PROVIDE JUST ENOUGH DRYING TO KEEP THE PIEDMONT BELOW HEAT ADVISORY CRITERIA. ISOLATED TO SCATTERED CONVECTION SHOULD ONCE AGAIN BEGIN NEAR THE BLUE RIDGE SUNDAY AFTERNOON...BUT INCREASINGLY MOVE OUT OVER THE ADJACENT FOOTHILLS...AND POSSIBLY EVEN THE PIEDMONT...IN SLIGHTLY BETTER WESTERLY SHEAR ALOFT. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... AS OF 240 PM SATURDAY...SHORT RANGE MODELS AGREE THAT THE AXIS OF THE H5 RIDGE WILL SHIFT EAST ACROSS THE ATLANTIC ON MONDAY. BROAD H5 TROF WILL SLIDE ACROSS THE APPALACHIANS ON TUESDAY. AT THE SFC...ATLANTIC HIGH PRESSURE COMBINED WITH AN GREAT LAKES LOW WILL ALLOW DEEP RETURN FLOW ACROSS THE DEEP SOUTH MONDAY AND TUESDAY. THE INFLUX MOISTURE AND FALLING HEIGHTS WILL LIKELY LEAD TO A BIT MORE CONVECTION EACH DAY...ESPECIALLY OVER THE MTNS. I WILL INDICATE SCHC TO CHC POPS ACROSS THE MTNS AND FOOTHILLS AND 10 POPS EAST. MONDAY...H85 TEMPS AND LLVL THICKNESSES SUPPORTS A FORECAST OF NEAR RECORD HIGH TEMPS. SEE CLIMATE SECTION BELOW. LOWERING FIELDS SHOULD RESULT IN A 3-4 DEGREE DROP IN HIGH TEMPERATURES ON TUESDAY. LOW/HIGH TEMPERATURES WILL REMAIN WELL ABOVE NORMAL...THE WARMER MEMBER OF THE TEMPERATURE GUIDANCE WAS USED IN THE FORECAST. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... AS OF 250 PM SATURDAY...I USED A BLEND OF THE GFS AND ECMWF FOR THE EXTENDED RANGE. WED THROUGH FRI...IT APPEARS THAT THE H5 RIDGE WILL RETURN ACROSS THE DEEP SOUTH. HOWEVER...LLVL THICKNESSES AND H85 TEMPS WILL REMAIN LESS THAN THE CURRENT HEAT WAVE. IN ADDITION...GULF AND ATLANTIC MOISTURE WILL REMAIN GREATER ACROSS THE FORECAST AREA. WARM TEMPERATURES AND MILD DWPTS WILL LIKELY ALLOW DIURNAL INSTABILITY TO DEVELOP ACROSS THE REGION EACH DAY. I WILL ADVERTISE A SLIGHT INCREASE IN COVERAGE THROUGH THE PERIOD...ANTICIPATING WEAK UPPER SUPPORT AND GREATER SFC CONVERGENCE INTO FRI AND SAT WITH A BREAK DOWN IN RIDGING. I WILL USE A BLEND OF HPC AND MEX TEMPERATURE GUIDANCE...SUPPORTING TEMPS AT OR ABOVE NORMAL THROUGH THE PERIOD. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... CONVECTIVE COVERAGE CONTINUES TO BLOSSOM THIS AFTERNOON ALONG THE NC BLUE RIDGE AND IN THE VICINITY OF THE SMOKIES. KAVL WILL SEE THE GREATEST CHANCE OF TSRA IN THE VICINITY OF THE AIRPORT...BUT VERY SLOW MOVEMENT OF THE THUNDERSTORMS WILL LIMIT COVERAGE. OUTSIDE OF THE MTNS...FEW TO SCATTERED CUMULUS ARE EXPECTED UNTIL SUNDOWN...WITH CLEARING SKIES OVERNIGHT. KAVL REACHED MVFR VSBY BRIEFLY THIS MORNING...AND A REPEAT LOOKS LIKELY TOWARD DAYBREAK SUNDAY. THE POTENTIAL FOR MVFR FOG WILL BE EVEN GREATER IF ANY TSRA ACTIVITY REACHES THE AIRPORT THIS EVENING. LIGHT W TO SW WINDS ARE EXPECTED THROUGH THE PERIOD. A VERY BRIEF PERIOD OF DUE WESTERLY FLOW IS POSSIBLE ONCE AGAIN AS MIXING DEVELOPS AT KCLT SUNDAY MORNING. CONVECTIVE CUMULUS WILL REDEVELOP WITH HEATING LATE SUNDAY MORNING. ONLY KAVL HAS A CHANCE OF SEEING ANY THUNDERSTORMS NEAR THE TERMINAL LOCATION PRIOR TO 18Z...BUT THE ODDS ARE FAIRLY REMOTE. OUTLOOK...THE HIGH PRESSURE RIDGE OVER THE AREA WILL START TO BREAK DOWN SUNDAY NIGHT THROUGH TUESDAY...BEFORE REASSERTING ITSELF BY MID WEEK. EXPECT ISOLATED TO SCATTERED AFTERNOON AND EVENING THUNDERSTORMS EACH DAY SUNDAY THROUGH THURSDAY. BRIEF MVFR VISIBILITY RESTRICTIONS CAN ALSO BE EXPECTED EACH MORNING AROUND DAYBREAK AT KAVL. && .CLIMATE... HERE ARE THE DAILY RECORD HIGH TEMPERATURES AND THE YEAR IN WHICH THEY LAST OCCURRED FOR GSP...CLT...AND AVL.
