How Bad Will the Storms Be?
As explained by NWS:
“The position of the warm front will have the greatest impact on the environment Wednesday afternoon and evening. Models want to bring the warm front into the area oriented along I-24 (with the warmest and most unstable air south and west of I-24 in the Slight/Enhanced/Marginal Risk areas) Wednesday afternoon. But, if that front moves further north and east, the severe threat will spread north and east with it.
Damaging wind gusts remain the primary threat with any severe thunderstorms that develop, but large hail, flooding, and a few tornadoes will all be possible.
