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, 11.7 hours before the alert went out and 151 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 NATIONAL WEATHER SERVICE COLUMBIA SC 200 PM EDT SUN AUG 21 2005 .SHORT TERM (TONIGHT THROUGH TUESDAY)... THE STRONG HEATING AND SURFACE TROUGH EXTENDING THROUGH THE FORECAST AREA ARE SUPPORTING THUNDERSTORMS THIS AFTERNOON. EXPECT COVERAGE WILL REMAIN ISOLATED BECAUSE OF THE UPPER-LEVEL RIDGING. INSTABILITY HAS BECOME MODERATE SO STRONG WIND MAY OCCUR WITH A FEW OF THE THUNDERSTORMS LATE THIS AFTERNOON AND EVENING. THE SURFACE TROUGH SHOULD CONTINUE TO EXTEND THROUGH THE FORECAST AREA MONDAY. EXPECT THUNDERSTORM COVERAGE WILL BE GREATER BECAUSE OF LOWERING H5 HEIGHTS AHEAD OF THE APPROACHING COLD FRONT. PLAN TO USE THE HIGHER MAV GUIDANCE. THE COLD FRONT APPEARS TO BECOME DIFFUSE...BUT WITH CONTINUED TROUGHING IN THE FORECAST AREA AND LOWER H5 HEIGHTS PLAN TO CONTINUE POPS AROUND 50 PERCENT MONDAY NIGHT AND TUESDAY WHICH IS CLOSE TO THE MAV GUIDANCE AND THE CONSENSUS POP. TEMPERATURES SHOULD BE JUST BELOW THE HEAT ADVISORY CRITERIA MONDAY BECAUSE OF MORE CLOUDINESS. THE GUIDANCE TEMPERATURES ARE CLOSE THROUGH THE PERIOD AND PLAN TO FOLLOW. && .LONG TERM (TUESDAY NIGHT THROUGH SUNDAY)...
