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 00:00Z, 1.7 hours before the alert went out and 143 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.

IN ADDITION...THE SEABREEZE IS STILL EVIDENT ON RADAR AND IS NOW INTO FAR WRN PORTIONS OF THE CWFA. THIS SHOULD INTERACT WITH THE DEVELOPING CONVECTION AND MAKE EXISTING STORMS GROW RATHER RAPIDLY WITH PLENTY OF MOISTURE TO WORK WITH (PWATS AOA 2) AND INSTABILITY (CAPES 2500-3500 J/KG AND LI/S OF -7 TO -10). GOING LATER INTO THE EVE...ONCE THE SEABREEZE LOSES ITS PUNCH...THE BOUNDARY TO THE NW WILL BECOME MORE OF A FOCUS IN THE SC COUNTIES BY 13/06Z PER THE RUC AND META AND SHOULD DO SO RATHER WELL.
