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.

Area forecast discussion, May 27, 10:33 AM EDT, 2 hours 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1033 AM EDT FRI MAY 27 2011

.SYNOPSIS...
A STATIONARY FRONT WILL REMAIN OVER THE AREA TODAY AND THEN
DISSIPATE.  AN UPPER LEVEL RIDGE WILL BUILD OVER OUR REGION AND
CREATE SUMMER LIKE WEATHER THROUGH MUCH OF NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AT 1430Z...THE LATEST RUC ANALYZED A VORT MAX ENTERING THE CWFA AS
IT MOVES THRU THE AXIS OF A SHARP UPPER TROF AXIS EXTENDING FROM
LAKE ERIE SOUTH TO THE FL PANHANDLE. THE OVERALL TROF IS PIVOTING
FROM NEUTRAL TO NEGATIVE TILT AND LIFTING OUT. BUT EMBEDDED
SHORTWAVE ENERGY WILL CONTINUE TO WORK THRU THE CYCLONIC
FLOW...KEEPING A CONDUCIVE DYNAMIC ENVIRONMENT FOR CONVECTION THRU
THE AFTN. IN THE LLVLS...A WEAKENING SFC WAVE WAS ANALYZED OVER THE
UPPER OHIO VALLEY...WITH A DISSIPATING STALLED COLD FRONT JUST WEST
OF THE APPALACHIANS TO THE NRN GULF. LLVL MOISTURE IS ABUNDANT TO
THE EAST OF THE BNDRY...WITH SFC DEWPTS IN THE 60S ACRS THE CWFA TO
LWR 70S ALONG COASTAL PLAIN. THE 12Z GSO/FFC SNDGS SHOW FCST CAPE
VALUES IN THE 1000-2000 J/KG RANGE...AND THE 14Z LAPS ALREADY SHOWS
OVER 1000 J/KG ALONG SERN FRINGE OF THE CWFA. SO LIKELY SHWRS/TSTMS
ACRS THE ERN 2/3RDS OF CWFA STILL LOOKS GOOD. FREEZING LEVEL ARND 12
TO 12.5 KFT...MOIST MID LVLS AND WEAKER SHEAR THAN LAST FEW DAYS
WILL KEEP SVR THREAT FAIRLY LOW. A FEW ISOLD STORMS PRODUCING LARGE
HAIL AND DAMAGING WINDS IS EXPECTED MAINLY OVER PIEDMONT COUNTIES.
THAT THREAT IS MENTIONED IN THE HWO. OTHERWISE...TEMPS LOOK ON TRACK
WITH MOSTLY CLOUDY SKIES AND WIDESPREAD SHWRS...HIGHS NEAR NORMAL.

AXIS OF DEAMPLIFYING EASTERN CONUS TROUGH IS PROGGED TO SHIFT
DOWNSTREAM OF THE CWFA TONIGHT AND WITH LAYER RH DIMINISHING
ACCORDINGLY...SHOWER CHANCES WILL DIMINISH AS THE NIGHT WEARS
ON...ALTHOUGH CONSIDERABLE CLOUDS SHOULD LINGER.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 225 AM FRIDAY... A DEEP LAYER RIDGE WILL GRADUALLY BUILD
OVER THE REGION THROUGH THE WEEKEND. A SW TO NE ORIENTED SFC RIDGE
AXIS WILL ALSO BUILD ACROSS THE REGION...KEEPING THE FLOW
LIGHT...BUT GENERALLY OUT OF THE S TO SE ACROSS OVER THE FA. MODEL
SOUNDINGS SHOW A LITTLE BIT OF A CAP...BUT ENOUGH MOISTURE SHOULD
POOL ACROSS THE MTNS AND FOOTHILLS FOR SCT AFTN CONVECTION ON
SATURDAY. POPS ARE LOWER ON SUNDAY AS THE RIDGE BUILDS ALOFT.
HOWEVER...THERE IS STILL A FAIR AMOUNT OF INSTABILITY...AND ISOLATED
TO SCT AFTN CONVECTION SHOULD DEVELOP OVER THE MTNS. TEMPS WILL RISE
INTO THE MID 80S ON SAT AND WILL APPROACH 90 ON SUN. TEMPS WILL RUN
5 TO 10 DEGREES COOLER OVER THE MTNS.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
AS OF 120 AM FRIDAY...A STRONG DEEP LAYER RIDGE WILL KEEP THE REGION
UNDER AN UNSEASONABLY HOT AIRMASS MONDAY THROUGH WEDNESDAY. WE HAVE
NO POPS MONDAY...A SMALL AREA OF SLIGHT CHANCE POPS OVER THE MTNS
TUE...AND A LARGER AREA OF SLIGHT CHANCE POPS OVER THE MTNS AND
FOOTHILLS AND WED. IN OTHER WORDS...WELL BELOW CLIMO POPS. THIS
SEEMS REASONABLE AS WE WILL BE A LITTLE SOUTH OF STRONG RIDGE.
HOWEVER...THE GFS IS QUITE UNSTABLE EACH DAY. I WON/T RAISE THE POPS
ON THIS SHIFT...BUT WE MIGHT HAVE A LITTLE BETTER COVERAGE THAN
ADVERTISED IN THE WRN ZONES EACH DAY. A BACK DOOR COLD FRONT IS
EXPECTED TO MOVE ACROSS THE REGION WEDNESDAY NIGHT. THE 00 UTC RUN
OF THE GFS MATCHES UP QUITE WELL WITH YDAY/S HPC FRONTAL POSITION IN
THIS REGARD. THE FRONT SHOULD BE ACCOMPANIED BY SCT
CONVECTION...THOUGH THE SYNOPTIC SCALE FORCING WILL BE WEAK.

&&

.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
AT KCLT...SHOWERS SHOULD AFFECT THE TERMINAL FROM MID-MORNING ONWARD
AND THERE ALSO REMAINS THE POSSIBILITY OF MVFR CONDITIONS EITHER IN
ADVANCE OF THE PCPN OR ACCOMPANYING HEAVIER SHOWERS. FROM LATE
MORNING INTO THE AFTERNOON...SHOWER ACTIVITY MAY OCCUR WITH EMBEDDED
TSTM. 06Z NAM DEPICTS A DEEP CONVECTIVE LULL FROM MID-AFTERNOON
ONWARD AS DEEP MOISTURE BAND MOVES OFF THE EAST. ADDITIONAL SHOWER
AND/OR TSTM DEVELOPMENT IS POSSIBLE INTO THE NIGHT AND LATE NIGHT
FLIGHT RESTRICTIONS LOOK PROBABLE.

ELSEWHERE...BAND OF WIDESPREAD SHOWERS ACRS THE WESTERN FA EARLY
THIS MORNING WILL CONTINUE TO MAKE STEADY EASTWARD PROGRESS THRU
MIDDAY WITH ADDITIONAL DEEP CONVECTIVE DEVELOPMENT IN WAKE OF LEAD
IMPULSE THIS AFTERNOON. EXPECT A HIGH LIKELIHOOD OF LOW CIG/VSBYS
OVERNIGHT.

OUTLOOK...A DRY AND WARM AIR MASS IS EXPECTED TO SETTLE OVER THE
FORECAST AREA THIS WEEKEND AND WILL REMAIN INTO THE MID WEEK.
DIURNAL SHRA/TSRA ARE POSSIBLE EACH AFTERNOON AND EVENING ACROSS THE
MTNS AND ADJACENT FOOTHILLS.
