The episode as NWS JAX wrote it up.
An active pattern as a mid level trough rotated over the region with a couple of embedded short wave troughs bringing a couple rounds of strong to severe storms across the local area. Best instability was over northeast Florida where more heating occurred prior to storm arrival under SW flow. Strong shear was present which favored wind gusts in storms.
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 Aug 7, 12:57 PM EST, 3 minutes earlier.
