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
Birmingham, AL (KBMX), launched 12:00Z, 11.2 hours before the alert went out and 39 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.

SURFACE FRONT REMAINS NORTHWEST OF THE AREA THIS AFTERNOON...BUT NUMEROUS SMALLER SCALE BOUNDARIES IN PLACE ACROSS CENTRAL ALABAMA. WHAT APPEARED TO BE AN UNDULAR BORE HAS GENERATED AN DIFFERENTIAL HEATING ZONE IN WEST CENTRAL ALABAMA AND AN OUTFLOW BOUNDARY WAS LOCATED FROM NEAR HEFLIN TO MONTGOMERY.
