The radar

The Greer radar (KGSP), 84 km from the middle of the area, began a volume at 20:06 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, 8.1 hours before the alert went out and 183 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, Jul 22, 3:18 PM EDT, 48 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
318 PM EDT SUN JUL 22 2012

.SYNOPSIS...
A WEAK RIDGE WILL BUILD ACROSS THE REGION FROM THE SOUTHEAST TONIGHT
AND REMAIN DOMINANT THROUGH EARLY PART OF THE WEEK. THEN A SERIES
SHORTWAVE TROUGHS WILL INFLUENCE OUR WEATHER THROUGH THE WEEKEND.

&&

.NEAR TERM /THROUGH MONDAY/...
NUMEROUS TSRA ACROSS THE NRN FOOTHILLS AND NWRN PIEDMONT WITH SLIDE
SOUTH AND EAST THRU THE AFTERNOON. SOLID SCT CONVECTION EXPECTED
ACROSS THE NRN MTNS AND SRN FOOTHILLS AND PIEDMONT. CHC OF
CONVECTION LESSENS SOUTH AND WEST OF THESE AREAS. KEPT SCT
CONVECTION OVER THE MTNS...WITH ISOLATED MOST OF NE GA AND THE
UPSTATE. STRONG INSTABILITY HAS DEVELOPED WITH LOTS OF SUNSHINE OVER
THE AREA. ALTHOUGH NOT EXTREME...DCAPE IS HIGHER THAN PAST COUPLE OF
DAYS AND IS FORECAST TO REMAIN MODERATE THRU THE AFTERNOON. STILL
EXPECT SVR CHC TO BE HIGHER TODAY WITH DAMAGING DOWNBURST WINDS THE
MAIN THREAT...AND FLOODING CHC TO BE LOWER WITH LOWER PW VALUES THAN
PREVIOUS DAYS.

CONVECTION SHUD DISSIPATE QUICKLY THIS EVENING LEAVING MOSTLY CLEAR
TO PARTLY CLOUDY SKIES. LOWS CONTINUE TO BE NEAR TO SLIGHTLY ABOVE
NORMAL.

RIDGE AXIS BEGINS TO STRENGTHEN MONDAY BUT REMAINS TO OUR SOUTHWEST.
ALTHOUGH THE NRN STREAM FLOW IS GENERALLY TO OUR NE...WE WILL BE
CLOSE ENUF FOR A SHORT WAVE RIDING THRU THE FLOW TO CROSS AT LEAST
THE NORTH AND ERN PORTION OF THE CWFA. H7 TEMPS INCREASE WITH THE
RIDGING...BUT THE NAM DOES NOT INCREASE AS MUCH AS THE GFS. THE TEMPS
AND DEWPOINTS ARE HIGH ENUF MONDAY AFTERNOON THAT SFC PARCELS WILL
OVERCOME THE CAP SO CONVECTION INITIATES...EVEN ON THE GFS. ALSO THE
SHORT WAVE SHUD PRODUCE ENUF FORCING TO OVERCOME THE CAP AS WELL. A
LEE TROF WILL REMAIN IN PLACE OVER THE AREA PROVIDING LOW LEVEL
CONVERGENCE. THEREFORE...HAVE INCREASED POP TO THE 40 PERCENT RANGE
OVER THE NORTH AND 30 PERCENT OVER THE SOUTH AND WEST CLOSER TO THE
RIDGE. INSTABILITY WILL NOT BE QUITE AS STRONG WITH THE WARMER MID
LEVEL TEMPS...BUT DCAPE WILL BE SIMILAR OR SLIGHTLY HIGHER THAN
TODAY...ISOLATED SVR AGAIN POSSIBLE. HIGHS A COUPLE OF DEGREES
WARMER THAN SUNDAY.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
AS OF 200 PM SUNDAY...WITH ENERGY PROGGED TO ROTATE INTO THE
NORTHEAST CONUS MONDAY NIGHT AND TUESDAY...UPPER HEIGHTS ATOP
THE CWFA WILL LOWER A TAD AND EFFECTIVE NW FLOW WILL INCREASE
LEADING TO DEVELOPING LEE/PIEDMONT TROUGHING. SENSIBLE WX FCST WILL
FEATURE SCATTERED...DIURNALLY ENHANCED TSTMS...ESPECIALLY ACRS THE
NORTHERN TIER OF THE CWFA. AIDED BY A LLVL DOWNSLOPE COMPONENT...
WILL PLAN ON BOOSTING MAX TEMPS A FEW DEG F ABOVE PERSISTENCE...
FEATURING PIEDMONT MIDDLE 90S.

NOT SURPRISINGLY GIVEN THE LINGERING PATTERN...THERE IS A CHANCE FOR
MCS ACTIVITY TO AFFECT A PORTION OF THE REGION THROUGH TUESDAY NIGHT
AND WILL PLAN ON MAINTAINING A HEDGE SLIGHT CHANCE POP FOR AREAS
NORTH OF I-40 INTO EARLY WEDNESDAY MORNING. THE MEAN PATTERN CHANGES
LITTLE THROUGH WEDNESDAY AS UPPER HEIGHTS CONTINUE TO FALL A BIT.
CONDITIONS LOOK TO REMAIN CONDUCIVE FOR ADDITIONAL DIURNALLY ENHANCED
TSTMS CWFAWIDE. WITH ADDITIONAL CLOUDS AND DEEP CONVECTION...AN
INFLUX OF LESS WARM AIR WILL MAKE INROADS INTO W NC.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AS OF 200 PM SUNDAY...THE LATEST MEDIUM RANGE MODELS INDICATE THAT
A FRONTAL BOUNDARY OVER THE OH VALLEY DROPS SOUTH ACROSS THE REGION
ON WEDNESDAY AS AN UPPER TROF DEEPENS OVER THE MID ATLANTIC REGION.
THEN THE FRONT PUSHES BACK TO THE NORTH BY THURSDAY AS A WEAK UPPER
RIDGE BUILDS IN FROM THE WEST. ANOTHER UPPER TROF DEVELOPS OVER THE
GREAT LAKES INTO THE MID ATLANTIC FRI-SAT WITH ANOTHER FRONTAL
BOUNDARY DROPPING SOUTH ACROSS THE REGION. WITH CONTINUED HIGH PW
VALUES AND MODERATE DIURNAL INSTABILITY...EXPECT SCATTERED AFTERNOON
THUNDERSTORMS EACH DAY. TEMPERATURES WILL REMAIN A COUPLE DEGREES
ABOVE AVG THROUGH THE PERIOD.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
AT KCLT...CONVECTION ONGOING CLOSE ENUF TO KCLT TO INCLUDE TEMPO VFR
TSRA WITH THIS PACKAGE. WILL KEEP THE TEMPO THRU 00Z AND AMD AS
CELLS APPROACH THE AIRFIELD. CONVECTION SHUD QUICKLY DISSIPATE THIS
EVENING. ANY LOW CLOUD SHUD REMAIN NORTH OF THE AIRFIELD OVERNIGHT.
CURRENTLY HAVE JUST MVFR VSBY...BUT IF TSRA MOVE OVER THEN MVFR
POSSIBLE. WIND SHUD RETURN SWLY THIS AFTERNOON...THEN LIGHT S TO
CALM OVERNIGHT WITH SWLY WIND MONDAY.

ELSEWHERE...CONVECTION APPROACHING KHKY AND HAVE INCLUDED MVFR TSRA
THERE. TSRA WILL BE NEAR KAVL AS WELL...BUT MUCH LESS CHC AT THE SC
SITES. THEREFORE...KEPT THEM CONVECTION FREE. CONVECTION SHUD
DISSIPATE QUICKLY THIS EVENING. LOW CLOUD POSSIBLE BY MORNING AT
KHKY WITH IFR FOG LIKELY AT KAVL. CONDITIONS COULD BE WORSE AT KHKY
WITH CONVECTION LIKELY TO MOVE OVER THIS AFTERNOON. BRIEF MVFR FOG
AROUND DAYBREAK AT KAND. ANY RESTRICTIONS SHUD LIFT QUICKLY MONDAY
MORNING. GENERALLY SWLY WIND THIS AFTERNOON BECOMES CALM OVERNIGHT
WITH W TO SW WIND MONDAY. KAVL THE EXCEPTION WITH SLY WIND BECOMING
CALM OVERNIGHT AND NLY MONDAY MORNING.
