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, Sep 5, 3:09 PM EDT, 1 hour 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
309 PM EDT MON SEP 5 2011

.SYNOPSIS...
A STATIONARY FRONT WILL REMAIN ACROSS OUR AREA TONIGHT AS THE
REMNANT TROPICAL LOW TRACKS NORTHEAST SPREADING DEEP MOISTURE OVER
THE CAROLINAS THROUGH TUESDAY.  THE LOW WILL MOVE OUT OF THE AREA
LATER IN THE WEEK AS IT CONTINUES TO WEAKEN.

&&

.NEAR TERM /THROUGH TUESDAY/...
HEAVY RAIN STILL LIKELY OVER PORTIONS OF THE MTNS AND ADJACENT
FOOTHILLS. SVR WX BECOMING THE MAIN THREAT OUTSIDE OF THE MTNS. COLD
FRONT REMAINS STALLED NEAR THE SPINE OF THE APPALACHIANS TONIGHT
WHILE THE REMNANT LOW FROM LEE MOVES NORTHEAST ALONG THE FRONT. MDLS
CONTINUE TO SHOW THE BEST FRONTOGENETICAL AND DEFORMATION ZONE
FORCING REMAINING WEST OF THE SPINE. THAT SAID...PW VALUES ACROSS THE
AREA ARE 2 STANDARD DEVIATIONS ABOVE NORMAL WHILE SLY LOW LEVEL
WINDS IN THE 30 KT RANGE WILL CONTINUE THRU THE NITE.
THEREFORE...THE MOST LIKELY LOCATIONS TO SEE WIDESPREAD HEAVY
RAINFALL WILL BE IN THE PRIME UPSLOPE AREAS ALONG THE BLUE RIDGE AND
NEAR THE TN BORDER CLOSER TO THE BETTER SYNOPTIC FORCING. THE HEAVY
RAIN OUTSIDE OF THOSE AREAS WILL LIKELY BE MORE ISOLATED AND
CONFINED TO LOCATIONS THAT SEE REPEATED CONVECTION AND/OR OVER MORE
URBAN ARES. WILL LEAVE THE FLOOD WATCHES AS IS...BUT INDICATE THE
NEW THINKING IN THE WORDING. WHILE THE FLOOD THREAT HAS
DIMINISHED...THE SEVERE CHANCES HAVE INCREASED. HEATING OUTSIDE OF
THE MTNS HAS LEAD TO MODERATE INSTABILITY ALONG AND SOUTH OF I-85.
BULK SHEAR AND HELICITY VALUES REMAIN QUITE HEIGHT. THIS COMBINED
WITH LOW LCL HEIGHTS WILL LEAD TO A SIGNIFICANT TORNADO THREAT
THROUGH THE EVENING AND POSSIBLY OVERNIGHT.

COLD FRONT BEGINS TO MOVE TUESDAY AS THE LOW MOVES ALONG THE FRONT
AND INTO OUR AREA. DRY SLOT MOVES IN BEHIND THE FRONT HELPING TO END
HEAVY PRECIP FROM WEST TO EAST ACROSS THE AREA OUTSIDE OF THE MTNS
DURING THE MORNING. HEAVY RAIN COULD LINGER ACROSS THE MTNS...AT
LEAST THRU THE MORNING. STRONG SLY LOW LEVEL FLOW AND MODERATE
INSTABILITY WILL CONTINUE AHEAD OF THE FRONT. THEREFORE...LOCATIONS
AHEAD OF THE FRONT WILL RETAIN A TORNADO THREAT UNTIL THE FRONT
MOVES EAST OF THE AREA DURING THE LATE AFTERNOON. EXPECT THE HEAVY
RAIN THREAT AND PRECIP TO DIMINISH ACROSS THE MTNS DURING THE
AFTERNOON WITH THE SVR THREAT DIMINISHING AS WELL.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 230 PM MONDAY...12Z GFS AND NAM IN GOOD AGREEMENT THAT REMNANT
LOW FROM ONCE TS LEE WILL BE OVER THE WESTERN CAROLINAS AT 00Z WED
WITH A CONVERGENCE ZONE EAST OF THE CENTER. EXPECT THAT A CONVECTIVE
LINE OF STORMS ASSOCIATED WITH THE CONVERGENCE AREA WILL BE JUST
EAST OF THE FORECAST AREA AT THE BEGINNING OF THE PERIOD WITH THE
AREA EAST OF THE MOUNTAINS DRY SLOTTED. HENCE EXPECT ONLY SOME
SCATTERED SHOWERS OVER THE MOUNTAINS AS THE SURFACE LOW MOVES
SLOWLY NE TUE NIGHT. THE UPPER LOW WEST OF THE MOUNTAINS IS
EXPECTED TO MOVE ONLY VERY SLOWLY NORTHWARD INTO THE LOWER OHIO
VALLEY BY THU. LOOKS LIKE A PERSISTENT DOWNSLOPE FLOW AND A DRYING
AIRMASS WILL PRECLUDE ANY SHOWERS OUTSIDE OF THE MOUNTAINS BOTH
WED AND THU. ENOUGH MOISTURE SHOULD REMAIN OVER THE MOUNTAINS FOR
WIDELY SCATTERED TO SCATTERED SHOWERS THROUGH THE PERIOD. THE
SHOWERS WILL BE DIURNALLY ENHANCED EACH AFTERNOON...AND UPSLOPE
AREAS COULD SEE A SHOWER ANY TIME. CONSIDERABLE CLOUDINESS ON WED
WILL TEMPER MAX TEMPS AND KEEP THEM BELOW AVERAGE...BUT WITH
INCREASING SUNSHINE ON THU EXPECT MAX TEMPS SHOULD TOP OUT NEAR
AVERAGE VALUES.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 1 PM MONDAY...THE EXTENDED PORTION OF THE FORECAST LEANED
HEAVILY ON THE HPC/ECMWF FORECAST. THE REMNANT UPPER LOW PREVIOUSLY
ASSOCIATED WITH TS LEE IS FORECAST TO CONTINUE TO MEANDER ACROSS THE
TN VALLEY THROUGH THE END OF THE WEEK AND THEN GRADUALLY MOVE
EASTWARD AND SLOWLY FILL ACROSS THE SOUTHERN APPALACHIANS THE
FIRST OF NEXT WEEK. PERSISTENT...BUT GENERALLY WEAK DOWNSLOPE FLOW
EAST OF THE MOUNTAINS THROUGH SUNDAY...AND A MID LEVEL INVERSION
SUGGESTS GENERALLY DRY WEATHER IN THE PIEDMONT AREAS WITH ENHANCED
CU FIELDS DURING THE AFTERNOON HOURS. IN THE
MOUNTAINS...SUFFICIENT MOISTURE AND LAPSE RATES SHOULD EXIST FOR
SOME LOW TOPPED SHOWERS TO DEVELOP DIURNALLY EACH AFTERNOON. ON
MONDAY...WITH THE UPPER TROUGH MOVING EASTWARD ACROSS THE
AREA...SCATTERED AFTERNOON SHOWERS POSSIBLE ALL AREAS.
TEMPERATURES THROUGH THE PERIOD WILL AVERAGE ABOUT A CATEGORY
BELOW SEASONAL NORMS.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
AT KCLT AND ELSEWHERE...CONDITIONS OUTSIDE OF THE MTNS HAVE NOT BEEN
AS DIRE AS PREV FCST AS RAIN HAS BEEN SPOTTY. THAT SAID...PRECIP IS
EXPECTED TO BECOME WIDESPREAD LATER THIS AFTERNOON OR EARLY EVENING
WITH AT LEAST MVFR CONDITIONS EXPECTED. CONDITIONS DETERIORATE INTO
THE IFR RANGE THIS EVENING OR OVERNIGHT AS PRECIP...LOW LEVEL
MOISTURE AND UPSLOPE FLOW CONTINUE. CONDITIONS SHUD IMPROVE OUTSIDE
OVER THE WRN NON-MTN SITES AFTER DAYBREAK AS PRECIP SLOWLY COMES TO
AN END. LOW CONDITIONS COULD CONTINUE AT KCLT/KAVL THRU THE END OF
THE PERIOD. S TO SE WINDS WILL CONTINUE THRU THE NITE WITH LOW END
GUSTS FROM TIME TO TIME. THIS COULD CAUSE SOME LOW LEVEL WIND SHEAR
PROBLEMS. WINDS REMAIN S TO SW TUE MORNING WITH LOW END GUSTS
POSSIBLE AGAIN.

OUTLOOK...CONDITIONS SHOULD IMPROVE DURING THE AFTERNOON AS DRY SLOT
WORKS IN FROM THE WEST...HOWEVER CLOUDS COULD LINGER OVER THE MTNS.
THE FORECAST FOR MID-WEEK IS VERY UNCERTAIN DUE TO LOW CONFIDENCE IN
THE EVENTUAL PROGRESSION OF A REMNANT LOW.
