NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Jul 28, 1:04 PM EST, 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 204 PM EDT SAT JUL 28 2012 .SYNOPSIS... A WEAK COLD FRONT WILL SLOWLY SETTLE SOUTHEAST ACROSS THE REGION THROUGH THE WEEKEND BEFORE GRADUALLY DISSIPATING ON TUESDAY. HIGH PRESSURE WILL THEN DOMINATE THROUGH THE MIDDLE OF NEXT WEEK. && .NEAR TERM /THROUGH SUNDAY/... AS OF 200 PM...DEWPOINTS HAVE MIXED OUT INTO THE LOW TO MID 60S ACROSS THE NORTHERN UPSTATE AND THE NC FOOHILLS DOWN TO CHARLOTTE. DEWPOINTS CONTINUE TO POOL TO THE EAST/SOUTH OF THE LEE TROUGH THROUGH THE SOUTHERN UPSTATE TO SOUTH OF CHARLOTTE WITH LOW TO MID 70S THERE. BASED ON THE DRYER AIR WORKING IN...EXPECT THAT CONVECTION WILL REMAIN WIDELY SCATTERED ACROSS WESTERN AREAS THIS AFTERNOON. THE BEST COVERAGE WILL OCCUR DURING THE LATE AFTERNOON/EARLY EVENING HOURS ALONG THE MOISTURE GRADIENT AND WHERE SBCAPES ARE THE HIGHEST IN EXCESS 2000J. LOOKS LIKE 55DBZ CORES TO 24K WILL BE ENOUGH FOR SEVERE TODAY BASED ON DCAPES >1000J. DAMAGING MICROBURSTS WILL BE THE PRIMARY SEVERE THREAT. THE AFTERNOON CONVECTION WILL BE DRIVEN BY A SHORT WAVE MOVING SE THROUGH THE AREA ALONG WITH A WEAKENING SURFACE COLD FRONT WHICH WILL SLIP INTO THE LEE TROUGH POSITION TONIGHT. AS THE UPPER WAVE DEPARTS AND WITH THE LOSS OF HEATING...CONVECTION SHOULD WANE ACROSS SOUTHERN AREAS BY 04Z. FOR THE OVERNIGHT...IT SHOULD BE CLEAR TO PARTLY CLOUDY AND WARM AGAIN WITH LOWS REMAINING ABOVE AVERAGE. AREAS OF MOUNTAIN VALLEY FOG ARE LIKELY LATE TONIGHT. ON SUNDAY...WEAK SURFACE HIGH PRESSURE WILL RIDGE SOUTHWARD ACROSS THE AREA AS THE WEAK FRONTAL/MOISTURE BOUNDARY MOVES SE OF THE AREA. FORECAST SOUNDINGS INDICATE THAT A MID LEVEL INVERSION WILL SERVE TO CAP ANY DEEP CONVECTION FROM DEVELOPING. THE ONLY EXCEPTION MAY BE THE HIGHEST PEAKS. WITH STRONG INSOLATION ON SUNDAY...EXPECT ANOTHER VERY WARM/TO HOT DAY. HIGHS WILL REACH THE LOW TO MID 90S OUTSIDE OF THE MOUNTAINS WITH LOW TO MID 80S MOUNTAIN VALLEYS. HOWEVER... DEWPOINTS ARE FORECAST TO MIX OUT INTO THE LOWER TO MID 60S...WITH EVEN SOME 50S IN THE MOUNTAINS...SO HUMIDITY LEVELS WILL BE BELOW MID SUMMER AVERAGE LEVELS. && .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/... AT 200 PM EDT SATURDAY...THE MEAN EAST COAST UPPER TROUGH WILL PERSIST FROM SUNDAY NIGHT THROUGH TUESDAY. A SHORTWAVE WILL MOVE INTO THE TROUGH ON SUNDAY NIGHT...ROUNDING ITS BASE ON MONDAY. THE MODELS SHOW THE GREATEST MOISTURE OFF TO OUR EAST AND SOUTH ALONG THE REMAINS OF A SURFACE FRONT...BUT MODEL TIME HEIGHTS SHOW A THIN MOIST LAYER AT AROUND 800 MB. THE GFS AND NAM HAVE THEIR USUAL DISPARITY IN REGARDS TO INSTABILITY...BUT EVEN A MEAN OF THE TWO WOULD HAVE CAPE EXCEEDING 1000 J/KG...AND PLENTY OF DRY AIR EXISTS FOR EVAPORATIVE COOLING. WITH WEAK SHEAR...PULSE TYPE SEVERE THUNDERSTORMS WOULD NOT BE OUT OF THE QUESTION. WEAK STEERING FLOW MAY ALLOW SOME THUNDERSTORMS TO PUT DOWN LOCALLY HEAVY RAINFALL... BUT WITH MOISTURE RATHER LIMITED...NO WIDESPREAD HYDROLOGICAL PROBLEMS ARE FORESEEN. TEMPERATURES WILL RUN AROUND NORMAL. AN UPPER IMPULSE WILL MOVE INTO THE TROUGH ON TUESDAY. THE MODELS SHOW MORE MOISTURE OVER THE AREA...AS THE REMAINS OF THE OLD BOUNDARY LIFT NORTH ACROSS OUR AREA AS A WARM FRONT. THE GFS SOUNDING FOR TUESDAY APPEARS QUITE SIMILAR TO MONDAY...EXCEPT THAT IT HAS SLIGHTLY BETTER WIND SHEAR. AGAIN...PULSE THUNDERSTORMS WILL BE THE MAIN MODE OF CONVECTION...WITH SLIGHTLY BETTER STEERING FLOW KEEPING RAINFALL TOTALS FORM BECOMING PROBLEMATIC...DESPITE DEEPER MOISTURE DEPICTED IN MODEL TIME HEIGHTS. TEMPERATURES WILL REMAIN NEAR NORMAL. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... AT 200 PM EDT SATURDAY...AN EAST COAST UPPER TROUGH WILL PERSIST FROM WEDNESDAY INTO FRIDAY...THEN WILL DEAMPLIFY ON SATURDAY. AT THE SURFACE...WEAK HIGH PRESSURE WILL REMAIN OVER OUR AREA...WITH NORMAL SUMMERTIME MOISTURE EXPECTED. WEAK UPPER IMPULSES MOVING THROUGH THE TROUGH WILL BE DIFFICULT TO TIME...BUT WILL BE THE BEST FORCING FOR ANYTHING OTHER THAN HEAT OR OROGRAPHICALLY INDUCED CONVECTION. POPS WILL BE HELD AT NEAR CLIMATOLOGICAL NORMALS...WITH CHANCE POPS IN THE MOUNTAINS...AND SLIGHT CHANCE IN THE LEE...MAXIMIZED WITH AFTERNOON HEATING. THE LOWEST POPS WILL BE ON SATURDAY...WITH THE EXPECTED INCREASE IN MID LEVEL TEMPERATURES AS THE UPPER TROUGH WEAKENS. TEMPERATURES WILL BE NEAR OF SLIGHTLY BELOW NORMAL UNDER THE UPPER TROUGH...WITH A SLIGHT INCREASE SATURDAY AS HEIGHTS RISE ALOFT. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... AT KCLT...MAIN ISSUE FOR THE NEAR TERM IS CONVECTIVE THREAT. BASED ON LATEST STORM SCALE MODEL RUNS...IT STILL LOOKS LIKE THUNDERSTORMS WILL BE NEAR OR OVER THE AIRFIELD IN THE 22Z-01Z TIMEFRAME AS AN UPPER WAVE PASSES BY ALONG WITH A WEAK FRONTAL BOUNDARY. AFTER CONVECTION PASEES SE OF THE AIRFIELD AROUND 01Z...EXPECT SCATTERING VFR DEBRIS CLOUDS FOR THE OVERNIGHT. SOME LIGHT FOG MAY DEVELOP AROUND SUNRISE IF RAIN OCCURS AT AIRFIELD. SUNDAY SHOULD BE A VFR DAY AS A CAPPING INVERSION WILL KEEP CONVECTIONIN CHECK.I ELSEWHERE...BEST CHANCE FOR THUNDERSTORMS WILL BE OVER EASTERN AREAS...SO WILL CARRY A TEMPO FOR TSRA AT KHKY LATE THIS AFTERNOON. ELSEWHERE...POPS TOO LOW TO WARRANT ANYTHING BUT A VCTS/CB FOR NOW. CONVECTION WILL WANE QUICKLY AFTER 00Z WITH SCATTERING VFR DEBRIS CLOUDS FOR THE OVERNIGHT. SOME MVFR FOG POSSIBLE AT KAVL LATE TONIGHT. SUNDAY WILL BE A VFR DAY WITH A CAPPING INVERSION KEEPING CONVECTION IN CHECK. OUTLOOK...SCATTERED AFTERNOON AND EVENING THUNDERSTORMS ARE EXPECTED EACH DAY THROUGH THE MIDDLE OF NEXT WEEK...WITH THE MOUNTAIN VALLEYS HAVING THE BEST CHANCE OF MORNING FOG OR LOW CLOUDS.
