The episode as NWS JAX wrote it up.
A short wave trough moved across SE GA in the afternoon and evening which enhanced diurnal storms over an unstable airmass.
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 8, 3:19 PM EST, 1 hour 51 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 419 PM EDT Thu Aug 8 2019 ...HEAT ADVISORY CONDITIONS POSSIBLE FOR FRIDAY... .NEAR TERM... Scattered showers and storms are continuing to build over the region along outflow boundaries and convergences, progressing eastward towards the coastline. A training of storms over the Ichetucknee area may lead to excessive rainfall and localized flooding, with convection finally dissipating later on this evening. Westerly flow will persist overnight and into tomorrow morning, with surface winds being consistently out of the southwest. Overnight low temperatures will be in the mid 70s for inland areas and in the upper 70s for coastal areas and beaches. .SHORT TERM /Friday and Saturday/... Northwesterly flow will become more westerly with the beginning of the weekend, as frontal boundary to the north begins to show signs of weakening. This will result in moist air with high PWAT values reaching as high as 2.3 inches. A weak low-level shortwave may serve to enhance storm development going into the weekend, but otherwise scattered diurnal showers are to be expected for the most part which will mostly disperse overnight. Max temps will peak on Friday with values ranging from the lower 90s for parts of inland northeast Florida, to just below 100 degrees for parts of inland southeast Georgia. Temperatures are expected to come down slightly during the weekend, with inland temps in the lower to mid 90s and coastal area temperatures being in the lower 90s for both days. Heat index temperatures are expected to range between 105-110 degrees, potentially resulting in Heat Advisory conditions on Friday and Saturday. Overnight low temperatures will be in the mid 70s for inland areas and in the upper 70s along the coastlines. .LONG TERM /Sunday through Wednesday/... Over the course of Sunday and Monday, the remnants of the frontal boundary will have completely moved off towards the northeast. By midweek, ridging over the southern Florida from out of the east along with a descending cold front to the north of Georgia will result in a strong southwesterly flow across the region. This flow will bring in very humid and moist conditions, with PWAT values measuring near 2.5 inches. This could lead to more widespread convection in the coming week. High temperatures are expected to cool very slightly by midweek, with high temperatures ranging between the lower to mid 90s for inland areas and in the lower 90s along the coast. Apparent "feels like" temps will be over 100 degrees during this span, with heat index temperatures reaching just below 110 for inland areas in southeast Georgia. Overnight low temperatures will be in the mid to lower 70s for inland areas and in the upper 70s for locations near coasts and shorelines. && .AVIATION... Small Pop-up showers and storms expected through the afternoon hours and have continued trend of VCSH to VCTS in the 18-20z time frame at all TAF sites, except have kept predominant shower activity at GNV as decent shower activity and isolated storms pushing in from the west. Some tempo MVFR CIGS will be possible at GNV/SGJ in the higher moisture levels there, while will remain mostly VFR at the TAF sites around JAX and SSI. Low level wind flow will be west around 10 knots except becoming S-SW along the coastal TAF sites this afternoon. Storm chances will fade at the TAF sites around sunset (00Z) with mainly VFR conds expected overnight. Some low stratus/fog will be possible just after sunrise at GNV/VQQ/SGJ and have placed some MVFR VSBYS and Scattered Clouds in the 500-800 ft range for now. && .MARINE... With the surface trough to the north and High Pressure ridging in the south, continue to expect mainly offshore S-SW flow at 10-15 knots with seas 2 to 4 feet. Sea breeze will remain pinned close to the coast with a slight shift to the S/SE at the beaches at 10-15 knots. Offshore moving storms will reach the local waters will continue to impact local waters throughout the afternoon and into the evening, with gusty winds associated with storms as a likely risk. Rip Currents: Persistent long period swell with late afternoon seabreezes warrants a continued Moderate Risk for Ne Fl and Se Ga beaches through Friday. && .PRELIMINARY POINT TEMPS/POPS...
