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

Charleston AFB, SC (KCHS), launched 12:00Z, 6.0 hours before the alert went out and 221 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Columbia, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 22, 1:46 PM EDT, 12 minutes earlier.

Area forecast discussion, Aug 22, 1:46 PM EDT, 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE COLUMBIA SC
146 PM EDT MON AUG 22 2005

.SHORT TERM (TONIGHT THROUGH WEDNESDAY)...
THE DIFFUSE FRONT EXTENDING THROUGH THE FORECAST AREA PLUS STRONG
HEATING HAS HELPED CAUSE SCATTERED THUNDERSTORMS THIS AFTERNOON.
EXPECT COVERAGE WILL CONTINUE TO INCREASE AS THE MID-LEVEL SHORTWAVE
TROUGH SHOWN ON THE WATER VAPOR IMAGERY MOVING INTO WESTERN GEORGIA
APPROACHES THE FORECAST AREA. THE HIGHER MAV POPS APPEAR BETTER
TONIGHT...MAINLY FOR THIS EVENING BECAUSE OF THIS FEATURE.
INSTABILITY HAS BECOME MODERATE WITH LI/S NEAR -7 IN THE SOUTH PART
SO SEVERE WIND GUSTS MAY OCCUR WITH SOME OF THE STORMS. THERE SHOULD
BE LESS OF A SEVERE HAIL THREAT BECAUSE OF RELATIVELY WARM MID-LEVEL
TEMPERATURES. THE LATEST SPC MESO ANALYSIS SHOWS H5 TEMPERATURES
NEAR -5. SLOW MOVEMENT AND HIGH PRECIPITABLE WATER ALSO SUPPORTS
VERY HEAVY RAIN WITH SOME OF THE THUNDERSTORMS.

BELIEVE THE DIFFUSE FRONT WILL REMAIN IN THE FORECAST AREA WITH
A SERIES OF MID-LEVEL SHORT WAVE TROUGHS THROUGH WEDNESDAY. MOST OF
THE GUIDANCE IS IN CLOSE AGREEMENT WITH THE MAV POPS AND PLAN TO
FOLLOW.

&&

.LONG TERM (WEDNESDAY NIGHT THROUGH MONDAY)...
THE THUNDERSTORM CHANCE APPEARS LOW DURING THE EXTENDED PERIOD. THE
GFS SHOWS SURFACE RIDGING DOMINATING THURSDAY AND FRIDAY. AN ONSHORE
FLOW SHOULD CAUSE AN INCREASE IN LOW-LEVEL MOISTURE SATURDAY THROUGH
MONDAY. H5 RIDGING SHOULD LIMIT INSTABILITY THROUGH THE PERIOD. PLAN
TO KEEP SLIGHT CHANCE OF MAINLY AFTERNOON AND EVENING THUNDERSTORMS.
