The radar

The Greer radar (KGSP), 128 km from the middle of the area, began a volume at 20:49 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

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.

The nearest sounding before it

Greensboro/Hi Pt, NC (KGSO), launched 12:00Z, 8.8 hours before the alert went out and 130 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, May 10, 3:00 PM EDT, 1 hour 49 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
300 PM EDT TUE MAY 10 2005

.SHORT TERM (TONIGHT THROUGH FRIDAY)...
COVERAGE OF DEEP CONVECTION WILL CONTINUE TO INCREASE THRU LATE DAY
ALONG AND AHEAD OF EASTWARD WOBBLING MID-LVL S/WV...CURRENTLY
SPINNING TOWARD NE GA. POCKETS OF MODERATE INSTABILITY COMBINED WITH
JUST WITH ENUF SHEAR...ESPECIALLY IN THE PIEDMONT...TO SUPPORT SOME
MULTI-CELL CLUSTERS INTO THE EARLY EVENING. ISOLATED SEVERE WEATHER
THREAT WILL CONTINUE AS WELL WITH PRIMARY THREAT BEING LARGE HAIL
THANKS TO LOW WET BULB ZERO HEIGHTS. GIVEN THE COMBINATION OF
WEAKENING DEEP LAYER FORCING AND BLYR STABILIZATION THANKS TO
LOSS OF HEATING...CVRG EXPECTED TO WANE SLOWLY DURING THE EVENING
HOURS.

ON WEDNESDAY...IT CONTINUES TO LOOK LIKE WE WILL BE UNDER MEAN
NORTHERLY FLOW THROUGH A DEEP LAYER BETWEEN BUILDING UPPER RIDGE TO
OUR WEST AND UPPER LOW ALONG COAST. SOME DEGREE OF LLVL EASTERLY FLOW
DEVELOPS WITHIN WEAKLY FORCED ATMOSPHERE...SO COULD BE DIURNAL FOCUS
OF TSTMS NEAR THE HIGHER TERRAIN OR PERHAPS EAST OF THE CWFA WHERE
BETTER LLVL CONVERGENCE LOOKS TO SET UP. AT ANY RATE...A SHOTGUN
SLIGHT CHANCE FOR DIURNAL STORMS FOR ALL AREAS WILL CONTINUE.

STRENGTHENING UPPER RIDGE TO BUILD OVER THE CWFA THURSDAY...LEADING
TO WHAT LOOKS LIKE A PRETTY SUPPRESSED ATMOSPHERE...BUT NAM/GFS IN
GOOD AGREEMENT WITH ORIENTATION AND MAGNITUDE OF E-W ORIENTED
INSTABILITY AXIS ACRS NC...SO A SLIGHT CHANCE FOR AFT/EVE STORMS
WILL BE PLACED IN THIS AREA. TRICKY FCST SETTING UP FOR THU
NITE/FRIDAY AS UPPER RIDGE LINGERS BUT A BACKDOOR FRONT APRCHS.
THIS BNDRY COULD BE THE FOCUS FOR DEEP CONVECTION...PROBABLY
JUST DURING THE DAYTIME HOURS ON FRIDAY...AND HOW MUCH COOLER AIR
WORKS INTO CENTRAL/WESTERN NC BEHIND FRIDAY LEAVES MAXES
QUESTIONABLE AS WELL.
&&

.LONG TERM (FRIDAY NIGHT THROUGH TUESDAY)...
HAVE CLOSELY FOLLOWED HPC SCENARIO OF ECMWF THROUGH THE MEDIUM
RANGE. THIS SCENARIO WILL BRING A SURFACE FRONT IN FROM THE WEST ON
SUNDAY THAT WILL LAY DOWN ACROSS THE FORECAST AREA ON MONDAY. AS A
RESULT...A THREAT OF SHOWERS AND THUNDERSTORMS WILL EXIST THROUGHOUT
THE MEDIUM RANGE PERIOD...PARTICULARLY SUNDAY AND MONDAY. WILL LIMIT
POP TO CHANCE AT THIS POINT. TEMPS WILL FOLLOW HPC GUIDANCE.
&&

.AVIATION...
PASSAGE OF UPPER LOW AND COLD AIR ALOFT WILL KEEP MODERATE
INSTABILITY ACROSS THE WESTERN CAROLINAS INTO THE EARLY EVENING.
EXPECT MOST TAF SITES TO EVENTUALLY HAVE A BRUSH WITH
THUNDERSTORMS...MOST LIKELY AT KAVL THROUGH THE MID AFTERNOON AND
KCLT DURING THE LATE AFTERNOON. WILL AMEND TAFS AS CONVECTIVE TRENDS
DICTATE. APART FROM CONVECTIVE STORMS...CLOUDS SHOULD REMAIN VFR.
CONVECTION SHOULD WANE IN THE MID TO LATE EVENING LEAVING A GREAT
DEAL OF CONVECTIVE DEBRIS OVERNIGHT. NEXT SET OF TAFS WILL MOST
LIKELY DEAL WITH FOG AT LOCATIONS THAT EXPERIENCE PRECIP. AFTER THE
FOG BURNS OFF...MAINLY CIRRUS WITH A LIGHT NE FLOW IN THE MORNING.
