The combination of a sagging surface front across south Georgia and the sea breeze fronts over a very unstable low level air mass produced widespread severe storms across the forecast area during the afternoon and evening hours. A passing upper level short wave trough also aided convection which enhanced mid level lapse rates during the afternoon.

The episode as NWS JAX wrote it up.
The combination of a sagging surface front across south Georgia and the sea breeze fronts over a very unstable low level air mass produced widespread severe storms across the forecast area during the afternoon and evening hours. A passing upper level short wave trough also aided convection which enhanced mid level lapse rates during the afternoon.
