Scattered severe storms affected Upstate South Carolina during the afternoon hours.
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 Jul 17, 1:33 PM EST, 1 hour 32 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 233 PM EDT TUE JUL 17 2007 .SYNOPSIS... A WARM AND MOIST AIR MASS WILL LINGER OVER THE AREA THROUGH THURSDAY. A COLD FRONT WILL CROSS THE AREA ON FRIDAY...FOLLOWED BY DRIER AND COOLER AIR THAT WILL LINGER THROUGH THE WEEKEND. && .NEAR TERM /THROUGH WEDNESDAY/... MAIN FORECAST PROBLEM IN NEAR TERM IS THE AMOUNT OF CONVECTION TO EXPECT EACH PERIOD. FOR TONIGHT...STILL EXPECTING RATHER WIDESPREAD COVERAGE OF THUNDERTORMS...AT LEAST DURING THE EVENING HOURS. THUNDERSTORMS COULD PERSIST UNTIL AROUND MIDNIGHT IN THE NC PIEDMONT/FOOTHILLS. MODEL DETAILS NOT EXACTLY IN AGREEMENT...BUT THEY DO AGREE THAT AN AREA OF DECENT LIFT/OMEGA WILL MOVE FROM NE GA...ACROSS UPSTATE SC AND INTO NC AROUND MIDNIGHT. LATEST RUC FORECAST ALSO SUPPORTS THIS IDEA. THEREFORE WILL FORECAST LIKELY POPS IN THE UPSTATE...WESTERN NC THIS EVENING TRANSITIONING INTO THE NC PIEDMONT FOOTHILLS 03Z-06Z TIMEFRAME. COULD HAVE A RATHER DECENT CONVECTIVE COMPLEX EVOLVE SO I HAVE ALSO BEEFED UP THE QPF FIELD FOR TONIGHT AS PRECIPITABLE WATER FORECAST TO BE AROUND 2 INCHES AND HAVE CODED THE MENTION OF HEAVY RAIN. EXPECT THINGS TO SETTLE DOWN AFTER MIDNIGHT WITH LOW CLOUDS/FOG FILLING IN BEHIND THUNDERSTORMS. STAYED WITH MOS BLEND FOR OVERNIGHT LOWS. ON WED. THE QUESTION AGAIN IS HOW MUCH CONVECTION TO EXPECT. FORCING DOES NOT APPEAR TO BE AS GOOD SO I HAVE ACTUALLY GONE BELOW SREF POPS. RESULT IS SOLID CHANCE POPS MOUNTAINS RANGING TO LOW CHANCE PIEDMONT AREAS. ANOTHER VERY WARM DAY IS IN STORE FOR WED PER MOS BLEND. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... THE UPPER TROUGH OVER THE EASTERN USA AMPLIFIES ON THURSDAY AND FRIDAY...AS A PAIR OF SHORTWAVES DIVES INTO ITS BASE. CONVECTIVE ACTIVITY WILL BE EXTINGUISHED WEDNESDAY NIGHT AS THE ATMOSPHERE STABILIZES. ALTHOUGH MODEL GUIDANCE POPS ARE RATHER LOW ON THURSDAY...DEEP MOISTURE...INSTABILITY...AND THE PASSAGE OF A WEAK UPPER IMPULSE SUGGEST THAT LOW CHANCE POPS ARE IN ORDER. BY THE TIME DIURNALLY DRIVEN ACTIVITY WANES THURSDAY EVENING...THE FIRST SHORTWAVE APPROACHES...SUGGESTING THAT CONVECTION MAY LINGER LATER INTO THE NIGHT. A COLD FRONT ASSOCIATED WITH THE SECOND AND STRONGER SHORTWAVE WILL CROSS THE AREA ON FRIDAY. MODEL TIME HEIGHTS DIFFER ON THE AMOUNT OF UPWARD VERTICAL MOTION WITH THIS BOUNDARY...AND THE GULF WILL BE CLOSED DURING ITS PASSAGE...SO FOR NOW POPS WILL BE LIMITED TO HIGH CHANCE. TEMPERATURES WILL BE SEVERAL DEGREES ABOVE NORMAL THURSDAY...DESPITE FALLING HEIGHTS...IN WEAK WARM ADVECTION. TEMPERATURES FALL TO AROUND OR JUST BELOW NORMAL ON FRIDAY UNDER INCREASED CLOUD COVER. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... AN ANOMALOUS UPPER LEVEL TROUGH WILL PERSIST OVER EASTERN NORTH AMERICA THROUGH THE EXTENDED PACKAGE. THE MAIN SURFACE FEATURE IS A FRONT WHICH STALLS SUFFICIENTLY FAR ENOUGH TO OUR EAST TO KEEP WIDESPREAD DEEP MOISTURE AT BAY. WITH A EASTERLY FLOW BEHIND THE FRONT...SOME CHANCE MAY EXIST FOR UPSLOPE OROGRAPHIC CONVECTION ALONG THE BLUE RIDGE ESCARPMENT...PARTICULARLY IN GA AND SC...WHICH WILL NOT BE AS DEEPLY INTO THE COOLER AND MORE STABLE AIR MASS. POPS HAVE BEEN LOWERED SIGNIFICANTLY FROM HPC GUIDANCE...BUT MAY STILL BE A BIT HIGH FOR HPC SKY COVER...WHICH WAS ADJUSTED UP SLIGHTLY. BETWEEN THE UNSEASONABLY LOW HEIGHTS ALOFT...AND THE COOLER SURFACE MASS...TEMPERATURES WILL BE BELOW NORMAL. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... RATHER COMPLICATED SET OF TAFS BECAUSE EXPECT CONVECTION TO BE RATHER WIDESPREAD LATE THIS AFTERNOON/EVENING AND MAYBE HANG ON AS LATE AS MIDNIGHT AROUND KCLT. RADAR ALREADY SHOWING SCATTERED THUNDERSTORMS OVER SC/NC WITH NUMEROUS OVER NE GA. ALTHOUGH GFS/NAM DIFFER IN THE THEIR DETAILS...THEY ARE IN AGREEMENT THAT AN AREA OF SIGNIFICANT LIFT/OMEGA WILL TRAVERSE UPSTATE SC INTO NC FROM ABOUT 00Z-06Z. RUC LENDS SUPPORT FOR THIS AS WELL. SO I AM TRENDING TOWARD FORECASTING A CONVECTIVE COMPLEX TO MOVE FROM NE GA...ACROSS UPSTATE SC AND INTO NC PIEDMONT BY 04Z. BULK OF THIS MAY STAY SOUTH OF KAVL. THUS...HAVE INCLUDED A 4 HOUR TEMPO GROUP FOR THUNDER AT ALL SITES WITH MVFR CONDITIONS. SINCE I AM EXPECTING QUITE A BIT OF RAINFALL WHICH SHOULD SATURATE LOWER LEVELS OF COLUMN...HAVE ALSO FORECASTED LATE NIGHT IFR STRATUS AND MVFR FOG. EXPECT IFR CONDTIONS TO IMPROVE TO VFR BY 15Z ON WED. AVIATION OUTLOOK...DIURNAL CONVECTION IS EXPECTED TO CONTINUE WED AND THU AFDTERNOONS. TEMPO MVFR CONDITIONS CAN BE EXPECTED IN ANY THUNDERSTORM...AND VERY BRIEF IFR VSBY POSSIBLE IN HEAVY DOWNPOURS. EARLY MORNING IFR/MVFR VSBY RESTRICTIONS DUE TO FOG CAN BE EXPECTED...ESPECIALLY WHERE AFTERNOON AND EVENING RAIN OCCURS...AND KAVL WILL SEE THE BEST CHANCE OF TEMPO IFR CONDITIONS EACH MORNING. A COLD FRONT WILL CROSS THE REGION ON FRIDAY WHICH SHOULD PROVIDE BETTER COVERAGE OF THUNDERSTORMS AND A BETTER CHANCE FOR A PERIOD OF MVFR/IFR CONDITIONS IN A THUNDERSTORM. THE FRONT WILL SHUNT RAINFALL AND MORNING FOG TO THE SOUTH OF THE REGION ON SAT AND SUN. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...NONE. NC...NONE. SC...NONE. && SYNOPSIS...JAT NEAR TERM...LG SHORT TERM...JAT LONG TERM...JAT AVIATION...LG
