What happened
The episode as NWS JAX wrote it up.
The east coast and west coast sea breezes interacted with outflows from storms over southeast Georgia. These boundaries merged across the Suwannee River Valley of north Florida during the evening hours as a short wave trough was passing over the region in the mid levels. This feature increased vertical instability, and surface based instability was high was CAPEs over 2500 J/kg. A few severe storms erupted from Lake City to Gainesville which produced hail and damaging winds.
