Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 15 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, Jul 17, 2:01 PM EDT, 2 hours 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
201 PM EDT TUE JUL 17 2012

.SYNOPSIS...
BERMUDA HIGH PRESSURE WILL CONTINUE TO CONTROL OUR WEATHER THROUGH
MID-WEEK. A FRONTAL BOUNDARY OVER THE OHIO VALLEY IS EXPECTED TO
DROP SOUTH...INTO THE SOUTHEAST STATES LATE FRIDAY. THE FRONT WILL
REMAIN OVER OR JUST SOUTH OF THE REGION THROUGH THE WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AT 200 PM EDT TUESDAY...THE CLOSED UPPER LOW OVER FL IS EXPECTED TO
OPEN UP AND DRIFT SLOWLY NORTHWEST INTO GA TONIGHT...WHILE A FLAT
RIDGE REMAINS FROM THE TN VALLEY TO THE MID ATLANTIC COAST.
CONVECTION DEVELOPING OVER THE MOUNTAINS THIS AFTERNOON WILL DRIFT
SLOWLY SE INTO THE FOOTHILLS. ADDITIONAL ACTIVITY IS EXPECTED TO
DEVELOP IN THE PIEDMONT LATE THIS AFTERNOON. MODEL SOUNDINGS
REMAIN FAVORABLE FOR GUSTY WINDS. ACTIVITY WILL DIMINISH WITH THE
LOSS OF HEATING THIS EVENING. OVERNIGHT LOWS WILL BR AROUND
CLIMATOLOGICAL NORMALS.

ON WEDNESDAY THE UPPER LOW OVER GA OPENS UP AND DRIFTS FARTHER
NORTH...BUT THE MODELS ARE NOT CLEAR ON WEATHER UPPER IMPULSES
ROUNDING THIS LOW REACH THE OUR AREA. MODEL SOUNDINGS REMAIN
SUPPORTIVE OF CONVECTION...WITH CAPE IN EXCESS OF 1000 J/KG.
CONVECTIVE COVERAGE SHOULD BE AT LEAST AS GREAT AS TODAY...AND EVEN
GREATER IF THE UPPER LOW CAN PROVIDE ADDITIONAL SUPPORT. MAXIMUM
TEMPERATURES WILL REMAIN ABOVE NORMAL AS THE UPPER RIDGE REMAINS
OVER THE AREA. THE HEAT INDEX IS EXPECTED TO APPROACH 100 DEGREES IN
AREAS ALONG AND EAST OF INTERSTATE 77...BUT SHOULD REMAIN BELOW
ADVISORY CRITERIA OF 105 DEGREES.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 200 PM TUESDAY...THE SHORT TERM PERIOD WILL GRADUALLY SEE
SOMEWHAT OF A PATTERN CHANGE BY THE CLOSE OF FRIDAY. THE WEAK UPPER
LOW IS FORECAST TO BE OVER THE MIDLANDS OF SC AT THE BEGINNING OF THE
PERIOD WHICH THEN SHOULD MOVE EASTWARD AS HEIGHTS FALL SOMEWHAT
ALONG THE EAST COAST THANKS TO A DIGGING UPPER TROUGH OVER NORTHERN
NEW ENGLAND. BY THE END OF THE PERIOD...A WEAK NW FLOW REGIME IS
FORECAST TO PREVAIL. AT THE SURFACE...A VERY WEAK PRESSURE PATTERN
WILL PERSIST WITH GENERALLY WEAK HIGH PRESSURE ACROSS THE SOUTHERN
APPALACHIANS WITH A LEE TROUGH TO THE EAST. WITH BOUNDARY LAYER
MOISTURE REMAINING HIGH...EXPECT THAT DIURNALLY ENHANCED CONVECTION
WILL BE THE RULE THROUGH THU. LATE DAY CONVECTION ON WED SHOULD WANE
DURING THE EVENING PER LOW LEVEL CIN ADVERTISED IN BUFKIT SOUNDINGS.
CONVECTIVE COVERAGE SHOULD RAMP UP AGAIN ON THU. SEE NO REASON TO
DEVIATE FROM THE RATHER ROBUST AFTERNOON POPS WITH THE GREATEST
COVERAGE MOUNTAIN AREAS. WILL BACK OFF POPS AGAIN THU NIGHT AS LOW
LEVEL CIN DEVELOPS.

THE NORTHERN STREAM TROUGH WILL CONTINUE TO DIG INTO FRI WITH SHEAR
GRADUALLY INCREASING TO ALMOST 20KT IN THE SFC-6KM LAYER. A WEAK
FRONT IS FORECAST TO ENTER THE AREA ON FRI. WITH THE SURFACE
CONVERGENCE AND INCREASING SHEAR EXPECT GOOD CONVECTIVE COVERAGE
WITH LIKELY POPS JUSTIFIED. SOME ORGANIZED CONVECTIVE CLUSTERS COULD
GET GOING ON FRI AND POSE AN ENHANCED SEVERE THREAT. USED A BLEND OF
BIAS CORRECTED MOS TO GENERATE TEMP FIELDS.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 2 PM TUESDAY...A WEAK COLD FRONT WILL SLOWLY SAG SOUTHWARD
FRIDAY NIGHT WITH A CONTINUING SHOWER/THUDNERSTORM THREAT
ESPECIALLY ACROSS SOUTHERN AREAS. THE FRONT WILL STALL OVER
OVER...OR JUST SOUTH OF THE FA ON SATURDAY. THE PRESENCE OF THE
BOUNDARY WILL SERVE TO GENERATE SHOWERS AND THUNDERSTORMS WITH THE
BEST COVERAGE OUTSIDE OF THE MOUNTAINS SAT AND SUN AFTERNOONS. THE
BOUNDARY GRADUALLY WASHES OUT BY MON WHICH MEANS WE SHOULD RETURN
TO A MORE TYPICAL JULY PATTERN...WITH SCATTERED DIURNAL
CONVECTION BOTH MON AND TUE. STAYED CLOSE TO HPC GUIDANCE. MAX
TEMPS ARE FORECAST TO BE A COUPLE CATEGORIES BELOW AVERAGE THROUGH
THE WEEKEND THANKS TO ENHANCED CLOUD COVER AND WEAK CAD REGIME.
TEMPS ARE FORECAST TO WARM TO NEAR NORMAL MON AND THEN A LITTLE
ABOVE AVERAGE ON TUE.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
AT KCLT...SCATTERED CONVECTION IS EXPECTED TO DEVELOP TODAY...BUT
UNLESS IT OCCURS OVER THE TERMINAL...A RESTRICTION IS NOT LIKELY.
CONFIDENCE IS HIGH ENOUGH TO CARRY TS AND A LOW VFR CIG WITH CB. A
GUIDANCE CONSENSUS DOES NOT FAVOR MORNING FOG...AND MODEL TIME
HEIGHTS SUGGEST LESS CUMULUS AND MORE CIRRUS AFTER MIDNIGHT. LIGHT
WINDS REA EXPECTED TO FAVOR THE SW BY LATER THIS AFTERNOON.

ELSEWHERE...CONVECTION WILL HAVE THE MOST COVERAGE IN THE
MOUNTAINS...MAKING KAVL MOST VULNERABLE...BUT CONFIDENCE IS NOT HIGH
ENOUGH FOR RESTRICTIONS. WILL CARRY TS AND LOW VFR CIG WITH CB THIS
AFTERNOON. LATE TONIGHT LOW CLOUDS SHOULD DECREASE...WHILE ANVIL
DEBRIS REMAINS. GUIDANCE STILL LIKE DAYBREAK FOG AT KAVL...BUT IS
NOT VERY SUPPORTIVE AT FOOTHILL SITES. GIVEN THAT GUIDANCE HAS BEEN
OVERDONE AT KAVL...VFR WILL BE MAINTAINED THERE AT THIS TIME. LIGHT
WINDS WILL TAKE ON A WESTERLY COMPONENT...EXCEPT AT KAVL WHERE THEY
WILL CHANNEL UP VALLEY FROM THE NW.

OUTLOOK...SCATTERED THUNDERSTORMS WILL CONTINUE LATE WEDNESDAY...
ESPECIALLY OVER THE MOUNTAINS. A COLD FRONT WILL REACH THE AREA
THURSDAY...REMAINING INTO THE WEEKEND...AND INCREASING THE CHANCE
OF THUNDER...LOW CIGS...AND FOG.
