The episode as NWS GSP wrote it up.
A well organized MCS moved into the North Carolina Mountains around 8 a.m. EDT. The line weakened as it crossed the mountains, though it still downed a number of trees and produced small hail. The line did not produce any additional severe weather after emerging into the foothills, though it did hold together as it moved across the foothills and western piedmont and even produced periodic small hail.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Apr 26, 6:06 AM EST, 1 hour 16 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 706 AM EDT THU APR 26 2012 .SYNOPSIS... A COLD FRONT WILL APPROACH THE AREA FROM THE NORTH RESULTING IN UNSETTLED WEATHER TODAY. THIS COLD FRONT IS EXPECTED TO BECOME STATIONARY FROM WEST TO EAST ACROSS OUR AREA FRIDAY AND SATURDAY. THE FRONT WILL MOVE OFF TO THE SOUTH SUNDAY AS CANADIAN HIGH BUILDS OVER THE REGION. THEN THE HIGH WILL LINGER THROUGH EARLY PART OF NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... AS OF 7 AM...A WELL ORGANIZED BOW ECHO WILL SWEEP INTO THE WESTERN NC MTNS AROUND 8AM AND WILL REMAIN UNTIL 10AM. THIS LINE WILL BRING A RISK OF DAMAGING WINDS AND HAIL...SPS HAS BEEN ISSUED. I WILL RAMP UP POPS AND MENTION SVR TSRA IN THE FORECAST. ELSEWHERE...WINDS CONTINUE TO REMAIN ABOVE GUIDANCE...I HAVE INCREASED EARLY MORNING WINDS SOUTH OF THE WARM FRONT. NORTH OF THE FRONT...I WILL ADD THE MENTION OF FOG. AS OF 4 AM...THE SFC WARM FRONT WAS LOCATED GENERALLY ACROSS THE NRN MTNS EAST ALONG THE I-40 CORRIDOR. THE FRONT IS EXPECTED TO MOVE NORTH OF THE CWA BY SUNRISE. OBS SOUTH OF THE FRONT SHOW VERY MILD TEMPERATURES...IN THE U50S ACROSS THE MTNS VALLEYS TO MID TO U60S EAST. THESE TEMPERATURES MAY COOL A COUPLE OF DEGREES BEFORE SUNRISE...MAINLY DUE TO DECREASING MID TO HIGH CLOUD COVER. A FEW SPOTS WITH THE MTN VALLEYS COULD SEE FOG EARLY THIS MORNING. OTHERWISE...MOST SITES WILL SEE SW WINDS GRADUALLY STRENGTHEN THROUGH SUNRISE...MARGINAL GUSTS POSSIBLE ACROSS NE GA AND SC EAST OF I-85. A MCS WAS OVER WESTERN KY AND TRACKING SE AT 8Z...IF THE MCS SURVIVES...IT WOULD REACH THE EXTREME WESTERN NC MTNS BETWEEN 13Z TO 14Z. I WILL KEEP POPS LOW THROUGH SUNRISE...THEN BEGIN TO INCREASE POPS TO CHC ACROSS THE MTNS FOR SHRA/TSRA BY 14Z. BY MID MORNING...THE CENTER OF THE CLIPPER IS FORECAST TO REACH THE NRN OHIO RIVER VALLEY AS HIGH PRESSURE REMAINS ACROSS FL. THE PRESSURE GRADIENT SHOULD RANGE BETWEEN 4 TO 6 MBS BY MID MORNING...RELAXING A MB OR TWO DURING THE AFTERNOON. MIXING TO 4 TO 5 KFT SHOULD RESULT IN GUSTY SW WINDS FROM 15Z THROUGH SUNSET...GUSTING TO 20 TO 25 KTS...A LITTLE STRONGER OVER THE SC UPSTATE. HIGH TEMPS ARE FORECAST TO RANGE FROM THE MID 70S ACROSS THE MTN VALLEYS TO LOW TO MID 80S EAST. ANY CONVECTION SHOULD REMAIN ACROSS THE NC MTNS THROUGH MID DAY. HOWEVER...THE COLD FRONT ASSOCIATED WITH THE CLIPPER IS FORECAST TO SWEEP ACROSS THE SOUTHERN APPALACHIANS LATE THIS AFTERNOON. THROUGH THE EVENING HOURS...THE SW TO NE FRONT MAY PUSH EAST OVER THE FOOTHILLS AND PIEDMONT. FORECAST SOUNDINGS ACROSS THE CWA THIS MORNING INDICATE A SIGNIFICANT H8 INVERSION. THIS INVERSION SHOULD KEEP THE FOOTHILLS AND PIEDMONT CAPPED THROUGH MUCH OF THE DAY. ACROSS THE MTNS...THE VALUES OF CIN ASSOCIATED WITH THE INVERSION IS LESS...AND THE POTENTIAL FOR UPSTREAM CONVECTION TRACKING ACROSS THE MTNS IS CERTAINLY POSSIBLE. I WILL KEEP CHC POPS OVER THE MTNS AND SCHC OR LESS POPS EAST THROUGH 20Z. INTO THE EARLY EVENING HOURS...THE APPROACH OF THE COLD FRONT WILL WEAKEN THE INVERSION AND CONVECTION SHOULD GRADUALLY DEVELOP ALONG AND AHEAD OF THE FRONT. I WILL INCREASE POPS TO LIKELY ACROSS THE TN BORDER COUNTIES AND INDICATE SCT POPS EAST. FORECAST SOUNDINGS ACROSS THE MTNS INDICATE THAT LLVL HELICITY WILL INCREASE TO AROUND 200 M2/S2...EHI ABOVE 2...AND SWEAT CLOSE TO 400. THE SHEAR COMBINED WITH SFC BASED CAPES AROUND 2K J/KG AND WBZ AROUND 7.5 KFT SHOULD FAVOR THE DEVELOPMENT OF SVR TS...ESPECIALLY ALONG THE TN LINE. SPC OUTLOOKS THIS AREA WITH A SLIGHT RISK...HIGHLIGHTING THE POSSIBILITY OF SVR HAIL AND WIND. WE WILL CONTINUE TO MENTION THE THREAT OF SVR TSRA ACROSS THE NC MTNS IN THE HWO. TONIGHT...CONVECTION WILL GRADUALLY ASHE OUT AROUND MIDNIGHT...LIKELY LEAVING ISO SHRA AND TSRA NEAR THE GA/SC/NC INTERSECTION INTO THE EARLY MORNING HOURS. NAM AND GFS INDICATE THAT COOLER THICKNESSES WILL SLOWLY PUSH SOUTH ACROSS THE REGION OVERNIGHT. USING A BLEND OF MOS...LOW TEMPERATURES ARE EXPECTED TO RANGE FROM THE L50S ACROSS THE MTNS TO NEAR 60 ACROSS THE UPPER SAVANNAH RIVER VALLEY. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... AS OF 330 AM THURSDAY...THE SHORT TERM FORECAST PICKS UP AT 12Z ON FRIDAY WITH THE EASTERN CONUS UPPER TROF SLOWLY LIFTING NE AND THE SOUTHERN STREAM BECOMES FAIRLY ZONAL. A WEAK UPPER RIDGING WILL BUILD INTO THE SOUTHEAST U.S. SATURDAY AND ANOTHER UPPER TROF OVER QUEBEC DIGS SOUTH BY EARLY SUNDAY. AT THE SURFACE...A LOW PRESSURE WILL MOVE OFF THE NEW ENGLAND COAST THURSDAY NIGHT/EARLY FRIDAY...AND DRAG A COLD FRONT SOUTHWARD INTO OUR AREA. THE LATEST MODELS CONTINUE TO INDICATE THAT THE FRONT BECOMES STATIONARY INVOF THE SOUTHERN EDGE OF THE CWA BY 12Z FRIDAY. THEN THE FRONT WILL LIFT BACK NORTHWARD BY FRIDAY AFTERNOON. THE LATEST MODEL SOUNDINGS HAVE TRENDED WEAKER WIND SHEAR AND LESS CAPE VALUES THAN THE PREVIOUS RUNS. NEVERTHELESS...WITH SOME DEGREE OF CONVERGENCE AND WEAK DIURNAL INSTABILITY...WE COULD SEE A DEVELOPMENT OF SHOWERS AND THUNDERSTORMS ALONG THE FRONTAL BOUNDARY. A MODEL BLEND FOR POPS RESULTS IN SOLID CHANCE POP WORKING FROM SW TO NE DURING THE DAY AND INTO FRIDAY EVENING. THE FRONT WILL LIFT NORTH OF THE AREA SATURDAY AS THE SUBTROPICAL HIGH BUILDS OVER THE SOUTHEAST U.S. THE FRONT WILL REMAIN JUST TO OUR NORTH KEEPING OUR WEATHER MOSTLY DRY AND WARMER TEMPS. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... AS OF 230 AM THURSDAY...THE MEDIUM RANGE FORECAST PICKS UP AT 12Z ON SUNDAY WITH WEAK UPPER RIDGING OVER THE CAROLINAS AND AN UPPER TROF PERSISTING OVER THE NORTHEASTERN STATES. HEIGHTS BEGIN TO RISE MONDAY AS THE UPPER TROF ROTATES OFF THE NEW ENGLAND COAST AND UPPER RIDGING BUILDS INTO THE SOUTHEAST U.S. BY EARLY NEXT WEEK. AT THE SURFACE...BOTH THE HPC AND THE GFS INDICATE THAT CANADIAN SURFACE HIGH OVER THE GREAT LAKES AND NORTHEAST STATES WILL PUSH A BACKDOOR COLD FRONT SOUTH ACROSS OUR FORECAST AREA ON SUNDAY. IN THE WAKE OF THE FRONTAL PASSAGE...COLD AIR DAMMING IS EXPECTED FOR SUNDAY NIGHT AND MONDAY. WITH DECENT MOISTURE AND WEAK LLVL FORCING...HAVE MENTIONED SLIGHT CHANCE POP OVER THE PIEDMONT AND SOLID CHANCE FOR NC MOUNTAINS AND FOOTHILLS. THE CONTINENTAL HIGH BECOMES SUBTROPICAL HIGH AND REMAINS OVER THE SOUTHEAST U.S. TUE/WED KEEPING A FRONTAL SYSTEM WELL TO OUR NORTH DURING THE PERIOD. HOWEVER...WE CANNOT RULE OUT THE POSSIBILITY OF AFTERNOON SHOWERS AND THUNDERSTORMS TUE/WED DUE TO INCREASING MOIST SOUTHERLY FLOW AND DIURNAL INSTABILITY. DAYTIME TEMPS WILL BE A FEW DEGREES BELOW NORMAL MON/TUE...THEN BACK ABOVE NORMAL WEDNESDAY. && .AVIATION /11Z THURSDAY THROUGH MONDAY/... AT KCLT...WINDS WILL REMAIN SSW AS A WARM FRONT MOVES NORTH. SW WINDS ACROSS THE TERMINAL THIS MORNING WILL GRADUALLY STRENGTHEN FROM THE PRE DAWN HOURS ON. A 4 TO 6 MB PRESSURE GRADIENT MAY DEVELOP BY MID MORNING AS THE CENTER OF THE CLIPPER LOW MOVES OVER THE OHIO RIVER VALLEY. MIXING TO 4 TO 5 KFT SHOULD RESULT IN GUSTY SW WINDS FROM 14Z THROUGH SUNSET...GUSTING TO 20 TO 25 KTS. A COLD FRONT ASSOCIATED WITH THE CLIPPER WILL PUSH NW TO SE ACROSS THE REGION DURING THE LATE AFTERNOON TO EARLY EVENING HOURS. SHRA AND TSRA SHOULD DEVELOP ALONG AND AHEAD OF THE FRONT...COVERAGE APPEAR TOO LITTLE AT THIS POINT TO ADD TO THE TAF. WINDS SHOULD DECOUPLE AND VEER NW AFTER 0Z. ELSEWHERE...FOG AND LOW CLOUDS WILL REMAIN OVER KHKY THROUGH 13Z...THEN THE WARM FRONT SHOULD LIFT NORTH. SW WINDS ACROSS THE TERMINAL THIS MORNING WILL GRADUALLY STRENGTHEN FROM THE PRE DAWN HOURS ON. A BAND OF SHRA/TSRA MAY REACH KAVL AROUND 14Z. A 4 TO 6 MB PRESSURE GRADIENT MAY DEVELOP BY MID MORNING AS THE CENTER OF THE CLIPPER LOW MOVES OVER THE OHIO RIVER VALLEY. MIXING TO 4 TO 5 KFT SHOULD RESULT IN GUSTY SW WINDS FROM 14Z THROUGH SUNSET...GUSTING TO 20 TO 25 KTS...A LITTLE STRONGER OVER THE SC UPSTATE. A COLD FRONT ASSOCIATED WITH THE CLIPPER WILL PUSH NW TO SE ACROSS THE REGION DURING THE LATE AFTERNOON TO EARLY EVENING HOURS. SHRA AND TSRA SHOULD DEVELOP ALONG AND AHEAD OF THE FRONT. WINDS SHOULD DECOUPLE AND VEER NW AFTER 0Z. OUTLOOK...A COLD FRONT WILL APPROACH FROM THE NORTH THROUGH FRIDAY. MAINLY PM SHOWERS/THUNDERSTORMS AND MORE WIDESPREAD RESTRICTIONS WILL BE POSSIBLE LATE IN THE WEEK AS THE FRONT DIPS FARTHER SOUTH INTO THE AREA.
