The episode as NWS JAX wrote it up.
A surface trough edged farther southward over Georgia while a surface ridge axis was south of the area. Light steering flow enabled the sea breezes to penetrate inland each day. Over a moist and unstable airmass, the sea breeze and outflow boundaries triggered scattered severe storms over the area during the afternoon and evening.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Jul 10, 2:09 PM EST, 5 hours 36 minutes earlier.
