The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Aug 11, 3:47 PM EST, 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 447 PM EDT THU AUG 11 2011 .SYNOPSIS... HIGH PRESSURE WILL MOVE FROM THE OHIO VALLEY TODAY TO THE EAST COAST ON FRIDAY. A COLD FRONT WILL THEN APPROACH THE AREA FROM THE NORTHWEST LATE SATURDAY AND MOVE OVER THE CAROLINAS EARLY SUNDAY BRINGING SHOWERS AND THUNDERSTORMS. && .NEAR TERM /THROUGH FRIDAY/... THE CONVECTION SHOULD BE FAIRLY ROBUST ACROSS THE ERN PIEDMONT EARLY THIS EVENING...WITH SE LOW LEVEL INFLOW AND SOME WESTERLY SHEAR OVER THE TOP ALLOW STORMS TO BECOME SOMEWHAT ORGANIZED AND SLIGHTLY LONGER LIVED. A WEAK SHORTWAVE IS MOVING IN FROM THE W...BUT THE ISOLD CONVECTION IN THE WRN HALF COULD BE ASSOCIATED WITH OUTFLOWS AS MUCH AS UPPER SUPPORT AT THIS POINT. POPS HAVE BEEN PUSHED TO CATEGORICAL IN THE ERN PIEDMONT THROUGH EARLY EVENING...WITH ISOLD ACROSS THE MTNS. OVERNIGHT...EXPECT THE CONVECTION TO DISSIPATE BUT SHOWERS COULD LINGER THRU THE NIGHT...ESP IN NC...DUE TO CONTINUED LOW LEVEL SELY FLOW AND DECENT LOW LEVEL MOISTURE. CLOUDS SHOULD LINGER AS WELL HELPING TO KEEP LOWS AROUND NORMAL. WEAK SHORT WAVE ENERGY MOVES ACROSS THE AREA FRIDAY IN THE LINGERING UPPER TROF. AT THE SFC...AN INVERTED TROF DEVELOPS OVER THE AREA BETWEEN HIGH PRESSURE PASSING BY TO THE NORTH AND A WEAK LOW PRESSURE CENTER OVER SRN GA. LOW LEVEL FLOW WILL REMAIN SELY WITH CONTINUED LOW LEVEL MOISTURE. EXPECT CONVECTION TO DEVELOP ONCE AGAIN AND COULD BE EVEN MORE WIDESPREAD THAN THU. HAVE KEPT POP AT SCT COVERAGE FOR NOW...BUT LIKELY MAY BE NEEDED OUTSIDE OF THE MTNS. WITH THE LINGERING CLOUDS AND LOWER THICKNESSES...HIGH TEMPS WILL BE RIGHT AROUND NORMAL. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... AS OF 130 PM THURSDAY...THE SHORT TERM FCST PICKS UP AT 00Z ON SATURDAY WITH THE BEGINNING OF A MARKEDLY MORE ACTIVE PERIOD. VARIOUS LOBES OF SHORTWAVE ENERGY IN THE MID/UPPER LVLS PROPAGATE TOWARDS THE FCST AREA AS THE UPPER LVL TROF DIGS DOWN OVER THE UPPER MISS RIVER VALLEY AND ARRIVES AT OUR DOORSTEP BY 00Z SUNDAY. ON SATURDAY...THE SFC HIGH SLIDES OFF THE ATLANTIC SEABOARD CAUSING OUR LOW LVL WINDS TO CONTINUE TO VEER AROUND TO SOUTHERLY. LOW AND MID LVL MOISTURE WILL QUICKLY RAMP UP IN THE AFTERNOON/EVENING WITH PWAT VALUES INCREASING ABOVE CLIMATOLOGY. LATEST MODEL SOUNDINGS GENERATE SOME HEALTHY INSTABILITY OVER MOST OF THE CWFA...HOWEVER BEST FORCING AND MOISTURE INFLUX IS EXPECTED SUNDAY MORNING DURING THE MINIMUM INSOLATION PERIOD. REGARDLESS...BY SAT EVENING I RAMP POPS UP TO LIKELY OVER MOST OF THE NC MTS AND HIGH END SOLID CHANCE ELSEWHERE. TEMPS SHOULD BE RIGHT AROUND CLIMO WITH HIGHS AROUND 90 OVER THE LOWER ELEVATIONS AND LOW TO MID 80S FOR THE MTS. ON SUNDAY...THE FRONTAL BOUNDARY WILL MOVE OVER THE FCST AREA EARLY WITH COOLER AND DRIER NWLY FLOW IN ITS WAKE. I EXPECT WIDESPREAD SHOWERS AND TS WITH SOME ORGANIZED SVR POTENTIAL...HOWEVER THE BEST DYNAMICS DO NOT COINCIDE WITH THE BEST HEATING...SO INSTABILITY WILL BE SOMEWHAT MINIMAL DURING THE FROPA. THINGS WILL DRY OUT SUNDAY EVENING AS THE FRONT MOVES SE OF THE CWA AND I LOWER POPS TO CHANCE OVER THE MTS FOR ANY LINGERING NW FLOW MOISTURE. TEMPS WILL LIKELY BE A BIT BELOW CLIMO WITH THE WIDESPREAD CLOUD COVER AND PRECIP. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... AT 2 PM EDT THURSDAY...AN UPPER TROUGH WILL REMAIN ALONG THE EAST COAST FROM MONDAY THROUGH THURSDAY. A COLD FRONT WILL DEPART OUR AREA TO THE SOUTHEAST ON SUNDAY NIGHT...THEN RELATIVELY COOL AND DRY HIGH PRESSURE WILL BUILD OVER THE AREA FROM THE NORTHEAST THROUGH THURSDAY. POPS WILL BE MINIMAL...AND MAINLY BASED IN THE MOUNTAINS FOR OROGRAPHIC EFFECTS. TEMPERATURES WILL RESEMBLE LATE SUMMER OF EARLY AUTUMN. && .AVIATION /21Z THURSDAY THROUGH TUESDAY/... AT KCLT...LINE OF TSTMS FILLING IN WEST OF THE AIRFIELD WILL YIELD TEMPO THUNDER AT KCLT THROUGH 23Z. EXPECT WIND GUSTS FROM THE NW AT LEAST 20 KT...BUT THESE COULD BE CONSIDERABLY STRONGER IF THE LINE OR CELLS ORGANIZE AS THEY MOVE THROUGH. OTHERWISE...WILL SEE VFR CIGS CONTINUE TONIGHT INTO FRI ON LIGHT LOW LEVEL EASTERLY FLOW. ELSEWHERE...THE MAIN CONVECTION IS ALREADY EAST OF A KAND TO KGSP TO KHKY LINE...BUT ADDITIONAL ISOLD TO SCT ACTIVITY WILL BE POSSIBLE AS AN UPPER SHORTWAVE ARRIVES AND ALONG LOW LEVEL OUTFLOWS FROM EARLIER STORMS. OTHERWISE...EXPECT VFR CIGS TO CONTINUE OVERNIGHT INTO FRI AS SELY FLOW ACTS ON LINGERING LOW LEVEL MOISTURE. BEST CHC FOR ANY FOG IS AT KAVL. DID NOT MENTION ANY SHRA BUT THEY COULD LINGER OVERNIGHT AT THE NC SITES AS WELL. EXPECT AN EVEN BETTER DAY FOR CONVECTION FRI BUT TOO EARLY TO INCLUDE IN TAFS ATTM. KEPT VFR CIGS THRU THE PERIOD. WINDS ARE TRICKY WITH WEAK LOW PRESSURE AND LEE TROF IN PLACE. HAVE TRENDED TOWARD A MDL BLEND WITH E TO SE WIND BECOMING NE OVERNIGHT. KAVL THE EXCEPTION WHERE N WIND CONTINUES. OUTLOOK...EVEN BETTER CONVECTION CHANCES SATURDAY AND SUNDAY. A COLD FRONT SHOULD BRING MUCH DRIER WEATHER MON AND TUE.
