Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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
Roanoke, VA (KRNK), launched 12:00Z, 7.5 hours before the alert went out and 26 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.

WITH MORE CONVECTIVE NATURE POTENTIAL EAST OF THERE PENDING
HEATING. SHORT RANGE MODELS ALSO SHOW BEST HELICITY/SHEAR ACROSS
THE FAR EASTERN PIEDMONT AS WELL WHERE LOW LEVEL FLOW WILL TURN
