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, 8.0 hours before the alert went out and 230 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 28, 2:04 PM EDT, 1 hour 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
204 PM EDT SAT JUL 28 2012

.SYNOPSIS...
A WEAK COLD FRONT WILL SLOWLY SETTLE SOUTHEAST ACROSS THE REGION
THROUGH THE WEEKEND BEFORE GRADUALLY DISSIPATING ON TUESDAY. HIGH
PRESSURE WILL THEN DOMINATE THROUGH THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
AS OF 200 PM...DEWPOINTS HAVE MIXED OUT INTO THE LOW TO MID 60S
ACROSS THE NORTHERN UPSTATE AND THE NC FOOHILLS DOWN TO CHARLOTTE.
DEWPOINTS CONTINUE TO POOL TO THE EAST/SOUTH OF THE LEE TROUGH
THROUGH THE SOUTHERN UPSTATE TO SOUTH OF CHARLOTTE WITH LOW TO MID
70S THERE. BASED ON THE DRYER AIR WORKING IN...EXPECT THAT
CONVECTION WILL REMAIN WIDELY SCATTERED ACROSS WESTERN AREAS THIS
AFTERNOON. THE BEST COVERAGE WILL OCCUR DURING THE LATE
AFTERNOON/EARLY EVENING HOURS ALONG THE MOISTURE GRADIENT AND
WHERE SBCAPES ARE THE HIGHEST IN EXCESS 2000J. LOOKS LIKE 55DBZ
CORES TO 24K WILL BE ENOUGH FOR SEVERE TODAY BASED ON DCAPES
>1000J. DAMAGING MICROBURSTS WILL BE THE PRIMARY SEVERE THREAT.

THE AFTERNOON CONVECTION WILL BE DRIVEN BY A SHORT WAVE MOVING SE
THROUGH THE AREA ALONG WITH A WEAKENING SURFACE COLD FRONT WHICH
WILL SLIP INTO THE LEE TROUGH POSITION TONIGHT. AS THE UPPER WAVE
DEPARTS AND WITH THE LOSS OF HEATING...CONVECTION SHOULD WANE ACROSS
SOUTHERN AREAS BY 04Z. FOR THE OVERNIGHT...IT SHOULD BE CLEAR TO
PARTLY CLOUDY AND WARM AGAIN WITH LOWS REMAINING ABOVE AVERAGE.
AREAS OF MOUNTAIN VALLEY FOG ARE LIKELY LATE TONIGHT.

ON SUNDAY...WEAK SURFACE HIGH PRESSURE WILL RIDGE SOUTHWARD ACROSS
THE AREA AS THE WEAK FRONTAL/MOISTURE BOUNDARY MOVES SE OF THE AREA.
FORECAST SOUNDINGS INDICATE THAT A MID LEVEL INVERSION WILL SERVE TO
CAP ANY DEEP CONVECTION FROM DEVELOPING. THE ONLY EXCEPTION MAY BE
THE HIGHEST PEAKS. WITH STRONG INSOLATION ON SUNDAY...EXPECT ANOTHER
VERY WARM/TO HOT DAY. HIGHS WILL REACH THE LOW TO MID 90S OUTSIDE OF
THE MOUNTAINS WITH LOW TO MID 80S MOUNTAIN VALLEYS. HOWEVER...
DEWPOINTS ARE FORECAST TO MIX OUT INTO THE LOWER TO MID 60S...WITH
EVEN SOME 50S IN THE MOUNTAINS...SO HUMIDITY LEVELS WILL BE BELOW
MID SUMMER AVERAGE LEVELS.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/...
AT 200 PM EDT SATURDAY...THE MEAN EAST COAST UPPER TROUGH WILL
PERSIST FROM SUNDAY NIGHT THROUGH TUESDAY. A SHORTWAVE WILL MOVE
INTO THE TROUGH ON SUNDAY NIGHT...ROUNDING ITS BASE ON MONDAY. THE
MODELS SHOW THE GREATEST MOISTURE OFF TO OUR EAST AND SOUTH ALONG
THE REMAINS OF A SURFACE FRONT...BUT MODEL TIME HEIGHTS SHOW A THIN
MOIST LAYER AT AROUND 800 MB. THE GFS AND NAM HAVE THEIR USUAL
DISPARITY IN REGARDS TO INSTABILITY...BUT EVEN A MEAN OF THE TWO
WOULD HAVE CAPE EXCEEDING 1000 J/KG...AND PLENTY OF DRY AIR EXISTS
FOR EVAPORATIVE COOLING. WITH WEAK SHEAR...PULSE TYPE SEVERE
THUNDERSTORMS WOULD NOT BE OUT OF THE QUESTION. WEAK STEERING FLOW
MAY ALLOW SOME THUNDERSTORMS TO PUT DOWN LOCALLY HEAVY RAINFALL...
BUT WITH MOISTURE RATHER LIMITED...NO WIDESPREAD HYDROLOGICAL
PROBLEMS ARE FORESEEN. TEMPERATURES WILL RUN AROUND NORMAL.

AN UPPER IMPULSE WILL MOVE INTO THE TROUGH ON TUESDAY. THE MODELS
SHOW MORE MOISTURE OVER THE AREA...AS THE REMAINS OF THE OLD
BOUNDARY LIFT NORTH ACROSS OUR AREA AS A WARM FRONT. THE GFS
SOUNDING FOR TUESDAY APPEARS QUITE SIMILAR TO MONDAY...EXCEPT THAT
IT HAS SLIGHTLY BETTER WIND SHEAR. AGAIN...PULSE THUNDERSTORMS WILL
BE THE MAIN MODE OF CONVECTION...WITH SLIGHTLY BETTER STEERING FLOW
KEEPING RAINFALL TOTALS FORM BECOMING PROBLEMATIC...DESPITE DEEPER
MOISTURE DEPICTED IN MODEL TIME HEIGHTS. TEMPERATURES WILL REMAIN
NEAR NORMAL.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
AT 200 PM EDT SATURDAY...AN EAST COAST UPPER TROUGH WILL PERSIST
FROM WEDNESDAY INTO FRIDAY...THEN WILL DEAMPLIFY ON SATURDAY. AT THE
SURFACE...WEAK HIGH PRESSURE WILL REMAIN OVER OUR AREA...WITH NORMAL
SUMMERTIME MOISTURE EXPECTED. WEAK UPPER IMPULSES MOVING THROUGH THE
TROUGH WILL BE DIFFICULT TO TIME...BUT WILL BE THE BEST FORCING FOR
ANYTHING OTHER THAN HEAT OR OROGRAPHICALLY INDUCED CONVECTION. POPS
WILL BE HELD AT NEAR CLIMATOLOGICAL NORMALS...WITH CHANCE POPS IN
THE MOUNTAINS...AND SLIGHT CHANCE IN THE LEE...MAXIMIZED WITH
AFTERNOON HEATING. THE LOWEST POPS WILL BE ON SATURDAY...WITH THE
EXPECTED INCREASE IN MID LEVEL TEMPERATURES AS THE UPPER TROUGH
WEAKENS. TEMPERATURES WILL BE NEAR OF SLIGHTLY BELOW NORMAL UNDER
THE UPPER TROUGH...WITH A SLIGHT INCREASE SATURDAY AS HEIGHTS RISE
ALOFT.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
AT KCLT...MAIN ISSUE FOR THE NEAR TERM IS CONVECTIVE THREAT. BASED
ON LATEST STORM SCALE MODEL RUNS...IT STILL LOOKS LIKE THUNDERSTORMS
WILL BE NEAR OR OVER THE AIRFIELD IN THE 22Z-01Z TIMEFRAME AS AN
UPPER WAVE PASSES BY ALONG WITH A WEAK FRONTAL BOUNDARY. AFTER
CONVECTION PASEES SE OF THE AIRFIELD AROUND 01Z...EXPECT SCATTERING
VFR DEBRIS CLOUDS FOR THE OVERNIGHT. SOME LIGHT FOG MAY DEVELOP
AROUND SUNRISE IF RAIN OCCURS AT AIRFIELD. SUNDAY SHOULD BE A VFR
DAY AS A CAPPING INVERSION WILL KEEP CONVECTIONIN CHECK.I

ELSEWHERE...BEST CHANCE FOR THUNDERSTORMS WILL BE OVER EASTERN
AREAS...SO WILL CARRY A TEMPO FOR TSRA AT KHKY LATE THIS AFTERNOON.
ELSEWHERE...POPS TOO LOW TO WARRANT ANYTHING BUT A VCTS/CB FOR NOW.
CONVECTION WILL WANE QUICKLY AFTER 00Z WITH SCATTERING VFR DEBRIS
CLOUDS FOR THE OVERNIGHT. SOME MVFR FOG POSSIBLE AT KAVL LATE
TONIGHT. SUNDAY WILL BE A VFR DAY WITH A CAPPING INVERSION KEEPING
CONVECTION IN CHECK.

OUTLOOK...SCATTERED AFTERNOON AND EVENING THUNDERSTORMS ARE EXPECTED
EACH DAY THROUGH THE MIDDLE OF NEXT WEEK...WITH THE MOUNTAIN VALLEYS
HAVING THE BEST CHANCE OF MORNING FOG OR LOW CLOUDS.
