NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Jun 12, 3:32 PM EST, 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 432 PM EDT TUE JUN 12 2012 .SYNOPSIS... A MUCH DRIER AIR MASS WILL BEGIN TO BUILD ACROSS THE SOUTHERN APPALACHIAN REGION TONIGHT AS A COLD FRONT MOVES OFF TO THE EAST. SURFACE HIGH PRESSURE IS EXPECTED TO REMAIN OVER THE WESTERN CAROLINAS AND NORTHEAST GEORGIA INTO EARLY NEXT WEEK. && .NEAR TERM /THROUGH WEDNESDAY/... AS OF 430 PM...A QUICK UPDATE TO ADJUST POP/TEMP/DWPT GRIDS TO FIT LATEST TRENDS. OVERALL...NO MAJOR CHANGES. THE BULK OF CONVECTION IS FIRING NEAR THE BLUE RIDGE ESCARPMENT. THIS ACTIVITY IS DRIFTING SE INTO THE ADJACENT FOOTHILLS AND PIEDMONT. SO THE HIGH POPS ACRS THE EASTERN ZONES FOR THE NEXT FEW HOURS STILL LOOKS GOOD. PREVIOUS DISCUSSION... CONVECTION DEVELOPING OVER THE MTNS AND BLUE RIDGE NEARLY AS EXPECTED. SHRA NEAR KCLT MOVING EASTWARD A LITTLE SLOWER THAN EXPECTED. STILL EXPECT NUMEROUS COVERAGE OVER MOST OF THE AREA AS THE CONVECTION FIRING OVER THE MTNS MOVES OFF INTO THE FOOTHILLS AND PIEDMONT AND ADDITIONAL CONVECTION FIRES OVER THE ERN CWFA. THE UPPER SAV RIVER VALLEY AND IMMEDIATE TN BORDER AREA HAS THE LEAST CHC OF ANY CONVECTION...BUT TOO SOON TO SAY THEY WON/T SEE ANY. FCST SOUNDINGS SHOW MODERATE INSTABILITY WITH VERY MOIST AIR MASS REMAINS IN PLACE OVER THE AREA THRU EARLY EVENING. MESOSCALE ANALYSIS CONFIRMS THIS WITH LITTLE TO NO DCAPE OVER THE AREA. DCAPE IS FORECAST TO INCREASE SLIGHTLY OVER NC. WITH LITTLE TO NO SHEAR IN PLACE...ORGANIZED OR WIDESPREAD SVR SEEMS UNLIKELY. HOWEVER...CANNOT RULE OUT AN ISOLATED WET MICROBURST. ISOLATED HEAVY RAIN COULD ALSO DEVELOP IF STORMS CAN TRAIN OVER THE SAME AREA GIVEN THE MOIST PW VALUES IN PLACE. EXPECT THE CONVECTION TO TAPER OFF WITH LOSS OF HEATING...BUT SHRA MAY LINGER INTO THE EARLY MORNING AS WEAK FORCING CONTINUES WITH A WEAK FRONT MOVING IN. PATCHY FOG EXPECTED AS WELL...UNLESS THE FRONT MOVES IN FASTER WITH DRIER LOW LEVELS AND WEAK MIXING. LOWS WARM ONCE AGAIN WITH READINGS 5 TO 10 DEGREES ABOVE NORMAL. DRIER AIR MASS MOVES IN BEHIND THE FRONT WED. HOWEVER...MOISTURE WILL LINGER/POOL OVER THE SWRN MTNS AND NC/SC/GA ESCARPMENT IN THE DEVELOPING ELY FLOW. THIS AREA WILL SEE THE BEST COMBINATION OF MOISTURE AND INSTABILITY TO PRODUCE MAINLY ISOLATED AFTERNOON CONVECTION. THE REST OF THE AREA SHUD SEE CU. COULD BE SOME BRIEF GUSTY WINDS THU MORNING AS MIXING TAPS THE SLIGHTLY STRONGER WINDS ON THE LEADING EDGE OF THE ENCROACHING AIR MASS. HIGHS SHUD BE WITHIN A COUPLE OF DEGREES OF NORMAL. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... AS OF 230 PM TUESDAY... BY WEDNESDAY EVENING HIGH PRESSURE SYSTEM WILL HAVE DRIFTED INTO EASTERN CANADA WITH SURFACE RIDGE EXTENDING SOUTHWARD INTO THE CAROLINAS AND EXTREME NORTHEAST GEORIGA. AIR MASS GENERALLY WILL BE DRY... BUT EASTERLY AND SOUTHEASTERLY FLOW AROUND SOUTHERN PERIPHERY OF HIGH WILL ADVECT SOME F MOISTURE WEST INTO THE SAVANNAH RIVER VALLEY AND SOUTHERN APPALACHIANS. AT THE PRESENT TIME... AIR MASS APPEARS TOO DRY AND STABLE BOTH THURSDAY AND FRIDAY TO SUPPORT PRECIPITATION EXCEPT FOR DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS OVER THE HIGHER TERRAIN. HIGH TEMPERATURES WILL BE FAIRLY UNIFORM BOTH DAYS RANGING FROM THE LOWER 80S IN THE NORTHEAST TO THE MID 80S IN THE SOUTH. MOUNTAIN VALLEY TEMPERATURES WILL RANGE FROM THE MID 70S TO LOWER 80S. LOW TEMPERATURES WILL BE IN THE LOWER AND MID 60S WITH SOME 50S IN THE MOUNTAIN VALLEYS. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... AS OF 200 PM TUESDAY...FRIDAY THROUGH MONDAY...DRY AND UNSEASONABLY COOL CONDITIONS ARE EXPECTED DURING THIS PERIOD WITH A PERSISTENT UPPER LOW OFF THE ATLANTIC COAST ALLOWING FOR A STRONG NORTHERLY JET TO RESIDE OVER THE REGION. AT THE SURFACE...CONTINENTAL HIGH PRESSURE WILL REMAIN CENTERED OVER NEW ENGLAND WITH RIDGING EXTENDING SW ACROSS OUR CWA. I WILL MAINTAIN DRY FORECAST OVER THE PIEDMONT AS MODEL SOUNDINGS SHOW STRONG CAPPING INVERSIONS DURING THE PERIOD. HOWEVER...A COMBINATION OF UPSLOPE FLOW AND DIURNAL INSTABILITY COULD SUPPORT THE DEVELOPING OF ISOLATED THUNDERSTORMS IN THE BLUE RIDGE MTNS EACH DAY. SO I CARRIED SLIGHT CHANCE POPS MAINLY IN THE AFTERNOON THERE. TEMPERATURES WILL REMAIN 5-10 DEGREES BELOW THE SEASONAL AVERAGES FRIDAY INTO MONDAY WITH A SLIGHT WARMING TREND BY TUESDAY. && .AVIATION /21Z TUESDAY THROUGH SUNDAY/... AT KCLT...MVFR CIGS WITH VCSH SHUD BECOME LOW VFR BY 20Z AS THE SHRA MOVE EAST. TSRA EXPECTED TO DEVELOP THRU THE LATE AFTERNOON WITH COVERAGE AND CONFIDENCE HIGH ENUF TO INCLUDE IN TAF. TIMING OF ANY RESTRICTIONS IS STILL IN QUESTION...SO KEPT TSRA VFR FOR NOW AND WILL AMD AS CELLS NEAR AIRFIELD. TSRA END BY EARLY EVENING WITH SOME SHRA POSSIBLE TIL MIDNIGHT. LOOKS LIKE MVFR FOG A GOOD BET...BUT TIMING MAY BE A LITTLE OFF...ESP IF WEAK FRONT MOVES IN A LITTLE FASTER WITH DRIER NLY FLOW. EXPECT VFR CU WITH NLY TO NELY WINDS AND POSSIBLE GUSTS WITH MIXING WED MORN. ELSEWHERE...XCPT FOR KHKY WHERE MVFR SHUD LIFT SHORTLY...VFR WITH INCREASING CHC OF TSRA THRU THE AFTERNOON. AS AT KCLT...COVERAGE AND CONFIDENCE HIGH ENUF TO INCLUDE IN TAF. TIMING OF ANY RESTRICTIONS IS STILL IN QUESTION...SO KEPT TSRA VFR FOR NOW AND WILL AMD AS CELLS NEAR AIRFIELDS. TSRA END BY EARLY EVENING WITH SOME SHRA POSSIBLE TIL MIDNIGHT. LOOKS LIKE MVFR FOG A GOOD BET MOST LOCATIONS...BUT TIMING MAY BE A LITTLE OFF...ESP IF WEAK FRONT MOVES IN A LITTLE FASTER WITH DRIER NLY FLOW. EXPECT VFR CU WITH NLY TO NELY WINDS AND POSSIBLE GUSTS WITH MIXING WED MORN. OUTLOOK...GENERALLY DRY CONDITIONS ARE NOW EXPECTED BEHIND A COLD FRONT WEDNESDAY AFTERNOON THROUGH SATURDAY. HOWEVER...ISOLATED AFTERNOON TSTMS WILL DEVELOP OVER THE MTNS EACH DAY...WHICH COULD HAVE SOME AFFECT ON OPERATIONS AT KAVL.
