The episode as NWS JAX wrote it up.
A surface ridge was across north Florida while a trough was draped across south central Georgia. A mid level short wave trough traversed southeast Georgia during the afternoon over a very moist and unstable air mass. Steering motion was slow but primarily to the east. Numerous storms fired across the area during the afternoon and evening as the sea breezes and their outflows converged between Highway 301 and Interstate 95.
