The episode as NWS JAX wrote it up.
Sea breezes and outflows converged across inland areas during the afternoon with strong to severe storms producing wet microbursts.
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 16, 12:10 PM EST, 4 hours 7 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 110 PM EDT SAT JUL 16 2016 .NEAR TERM /Through Sunday/... Storms were developing along the east coast and west coast sea breezes, and also across the interior this afternoon. Some storms may become strong to possibly severe, with strong wind gusts, frequent lightning and heavy downpours. Storms should merge across the interior late this afternoon and into the early evening before dissipating with loss of daytime heating. Debris clouds will linger into the overnight hours before clearing. Overnight lows will be in the 70s. Bermuda ridge axis across the middle of the region will lift northward to southeast Georgia on Sunday, providing a light southeasterly steering flow. The east coast sea breeze will push inland a little quicker, with storms pushing into the interior and the western side of the region by the early evening. Locally heavy rainfall and gusty wet downbursts are possible. Near normal to slightly above normal high temperatures are expected, with highs in the low to mid 90s. Heat indices will be in the 102-107F range once again. .SHORT TERM.../Sunday Night Through Tuesday/... Western Atlantic surface high pressure ridge axis will slide from just North of the region Sunday night to near the FL/GA line Monday afternoon, where it will remain nearly stationary through Tuesday. As the ridge slides South a trough of low pressure will move into the Southeastern states. With this pattern the flow will be largely onshore. This will allow the East coast sea breeze to push further inland. Will focus most convection Monday afternoon West of interstate 95. Will again focus convection more inland Tuesday, but the proximity of the trough will also help to enhance convection over SE GA. Temperatures this period will trend near to slightly above normal. && .LONG TERM.../Tuesday Night Through Saturday/... Persistent pattern with surface ridge over Western Atlantic will break down toward the end of the week. Convective focus will be inland early in the period due to onshore flow, then become more broad in coverage with the pattern change. Temperatures are expected to remain at or above normal this period. && .AVIATION... Showers and storms were forming along the east coast sea breeze and also developing across the interior this afternoon. Brief MVFR/IFR conditions are possible for any storms that move near/over the TAF sites into the early evening. VFR conditions forecast overnight with light winds. Patchy ground fog is possible at KVQQ near daybreak. && .MARINE... The evening wind surge is creating southerly winds in the 10-15 knot range tonight. The axis of western Atlantic ridging will extend across the southeast Georgia waters on Sunday. Southerly surface winds Sunday morning will become southeast in the near shore waters during the early afternoon hours as the sea breeze pushes inland. East to southeast winds will prevail over the regional waters Monday and Tuesday. Rip Currents: Low risk. && .PRELIMINARY POINT TEMPS/POPS...
