Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 20 minutes after it went out.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Aug 23, 11:15 AM EDT, 2 hours 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1115 AM EDT THU AUG 23 2007

.SYNOPSIS...
AN UPPER RIDGE WILL REMAIN OVER THE SOUTHEAST THROUGH THE END
OF THE WEEK...BEFORE A COLD FRONT APPROACHES THE WESTERN CAROLINAS
LATE IN THE WEEKEND. THE FRONT WILL BECOME STATIONARY OVER THE
REGION AND SLOWLY DISSIPATE EARLY NEXT WEEK AS THE UPPER RIDGE
BUILDS BACK OVER THE REGION ONCE AGAIN.

&&

.NEAR TERM /THROUGH TONIGHT/...
SKIES ARE CLEARING OUT OVER MOST OF THE CWFA AS OF 11 AM...WITH SOME
CU BEGINNING TO DEVELOP OVER SOME THE WESTERN MTNS AND ACROSS THE
UPSTATE. THE STALLED BOUNDARY THAT IS BISECTING NC ALONG I-77 MAY
HELP INITIATE SOME CONVECTION ACROSS THE I-77 CORRIDOR. ALSO...A
SLIGHT UPSLOPE COMPONENT TO THE LOW LEVEL WIND FLOW...SHOULD HELP
CONVECTION DEVELOP OVER THE MTNS AND FOOTHILLS BY MID AFTN. MADE
MINOR ADJUSTMENTS TO POP...MAINLY INCREASING TO SOLID CHC ACROSS THE
I-77 CORRIDOR AND SOUTHERN UPSTATE COUNTIES...WHERE DIFFERENTIAL
HEATING BOUNDARY IS LOCATED. BASED ON 12Z GSO SOUNDING AND RUC/NAM12
DATA...SEVERE THREAT THIS AFTN LOOKS UNCHANGED FROM EARLIER
THINKING. SO FEEL HWOGSP IS IN GOOD SHAPE.
OTHERWISE...TEMP/DEWPOINTS/WINDS ALL LOOK ON TRACK FOR THE REST OF
TODAY. MAX TEMPS EXPECTED TO BE IN THE LOWER 90S ACROSS NE
ZONES...TO MID 90S ACROSS THE UPSTATE.

SHRA AND TSRA WILL GRADUALLY DIMINISH THIS EVENING AND DEBRIS CLOUDS
SHOULD LINGER UNTIL MIDNIGHT. OTHERWISE...TONIGHT SHOULD BE FAIRLY
QUIET AND DRY. LOW TEMPERATURES FRI AM SHOULD FALL IN THE LOW TO MID
70S BY SUNRISE.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
AXIS OF THE H5 RIDGE WILL EXTEND NE TO SW ACROSS THE FORECAST AREA
ON FRIDAY. SO DEEP LAYER FORCING WILL BE ABSENT. HOWEVER...LLVL
UPSLOPE FLOW WILL AGAIN BE PRESENT WITH GOOD CONVERGENCE ACROSS THE
HIGH TERRAIN. BOTH THE NAM AND GFS HAVE A MODERATE AMOUNT OF CAPE
OVER THE MOUNTAINS AND WESTERN FOOTHILLS DURING THE AFTERNOON...WITH
LESS INSTABILITY OVER OVER THE PIEDMONT. PLAN TO CARRY 30/40 POPS
MTNS AND FOOTHILLS AND 20 POPS FARTHER EAST. LLVL THICKNESSES ARE UP
AROUND 1340 ON THE NAM AND 1335 ON THE GFS. THIS IS CERTAINLY GOOD
FOR 90S IN THE MOUNTAINS AND FOOTHILLS. AND WITH HIGHER
DEWPOINTS...IT WILL STILL ABOUT AS BAD AS IT DID ON THOSE DAYS WE
HIT TRIPLE DIGIT HIGHS OF LATE.

A NORTHERN STREAM LONG WAVE TROF DIMPLES THE WESTERLIES ON SATURDAY.
IT LOOKS WEAKER THAN IT DID ON PREVIOUS RUNS...WHICH HAS BEEN PAR
FOR THE COURSE FOR THIS SUMMER. THE H5 RIDGE AXIS...DESPITE
WEAKENING A LITTLE...WILL STILL EXTEND FROM NE TO SW ACROSS THE
MOUNTAINS. SO ONCE AGAIN THERE WILL BE LITTLE IN THE WAY OF UPPER
LEVEL FORCING. THE LLVL FLOW WILL BE EVEN WEAKER ON SATURDAY...BUT I
SUSPECT WINDS IN THE 1000-850 LAYER WILL TAKE ON A SLIGHTLY
STRONGER WESTERLY COMPONENT AHEAD OF THE LONG WAVE OVER ERN
TN...WHICH SHOULD CONTINUE GOOD CONVERGENCE ACROSS THE MOUNTAINS.
THE NAM DOES THIS AND DEVELOPS QUITE A BIT OF CONVECTION OVER THE
MOUNTAINS AND ACROSS THE LEE AS A RESULT...AND I/LL KEEP SOLID
CHANCE POPS OVER THE HIGH TERRAIN AND FOOTHILLS TO ACCOUNT FOR THIS.
IF THE NAMS/S 1450+ METER THICKNESS VERIFY ON SAT...WE MAY BE
LOOKING AT HIGHS APPROACHING 100 AGAIN IN THE LEE.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
LATEST GFS TAKES A SURFACE FRONT ABOUT AS FAR EAST AS THE NC MTNS
SUNDAY AFTERNOON. WITH DOWNSLOPE FLOW AHEAD OF THE FRONT...MAX TEMPS
SHOULD ONCE AGAIN BE WELL IN THE 90S. AFTER COLLABORATING WITH
NEIGHBORING OFFICES...I RAISED MAX TEMPS A FEW DEGREES. I KEPT IN
SCATTERED SHOWERS AND THUNDERSTORMS AS THERE SHOULD BE SOME
CONVECTION WITH THE FRONT AND A WEAK H5 SHORT WAVE...BUT I WOULDN/T
EXPECT COVERAGE WL BE ANY GREATER THAN IN THE TWO PRECEDING DAYS.
HEIGHTS RISE AGAIN NEXT WEEK...AND I NOTICE THAT THE GFS LAYER RH/S
IN THIS RUN ARE LOWER THAN THEY HAVE BEEN IN PAST RUNS IN THE
MON-WED TIME RANGE. I DIDN/T CHANGE ANYTHING BEYOND SUNDAY WITH THIS
PACKAGE...BUT I WOULD LOOK FOR A DRIER AND WARMER TREND IN THE
FORECAST AS THE RIDGE LOOKS AS IF IT WILL ONCE AGAIN BE STRONGER...
DRIER AND FARTHER WEST THAN INITIALLY EXPECTED.

&&

.AVIATION /15Z THURSDAY THROUGH MONDAY/...
STILL SOME MVFR CIGS AT HKY...BUT LOOK TO MIX OUT TO 6000 OR MORE FT
BY 18Z. OTHERWISE...VFR THIS AFTN WITH SCT TS ACROSS THE REGION (SEE
BELOW).

THIS AFTERNOON...THE CENTER OF THE H5 RIDGE PUSHES WEST...ALLOWING A
WEAK VORT TO SLIDE SOUTH ACROSS THE CENTRAL CAROLINAS. MODERATE
INSTABILITY...WEAK LIFT...AND INVERTED PIEDMONT TROF SHOULD YIELD
SOME DEEP CONVECTION. AT THIS TIME...THE GREATEST COVERAGE IS
EXPECTED ALONG THE I-77 CORRIDOR AND THE HIGHER TERRAIN AFTER 18Z. I
WILL INCLUDE A MENTION OF VCSH OR VCTS AT ALL TERMINALS THIS
AFTERNOON. I WILL TEMPO TSRA FOR ALL TERMINALS (SAVE KCLT) FROM
20-02. NORTHEAST TO EAST WIND SHOULD CONTINUE ACROSS THE TERMINALS
THROUGH THE PERIOD...REMAINING LESS THAN 10 KTS.

ISOLATED TO WIDELY SCATTERED AFTERNOON CONVECTION AND LIGHT MORNING
FOG WILL BE POSSIBLE THROUGH THE REMAINDER OF THE WEEK...ESPECIALLY
IN THE MTNS. COVERAGE OF CONVECTION MAY INCREASE OVER THE WEEKEND...
AS A FRONT APPROACHES FROM THE NORTHWEST.

&&

.GSP WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
NC...NONE.
SC...NONE.
