The episode as NWS JAX wrote it up.
Prevailing SW flow forced the sea breeze merger toward the Atlantic coast in the afternoon and evening where a few strong to severe storms produced gusty winds and some wind damage.
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 18, 12:49 PM EST, 2 hours 56 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 149 PM EDT Thu Jul 18 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... Issued at 147 PM EDT Thu Jul 18 2024 For the latest NE FL and SE GA Daily Key Messages please visit: https://www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf A short wave trough moving west to east across SE GA enhanced afternoon showers and storms with a broken line of west coast sea breeze convection pressing toward the east coast across NE FL. The east coast sea breeze was starting to move inland triggering additional isolated showers and storms near the Atlantic coast. Expect a continued increase in storms over the next 2-4 hrs toward the I-95 corridor and St. Johns River basin as westward moving convection converges with the east coast sea breeze. Another area of enhanced area of storms will likely focus across parts of SE GA and NE FL roughly from the Okefenokee Swamp toward the St. Marys river where outflows converge later this afternoon. The main hazards in storms will continue to be gusty wet downbursts, with magnitude potential a little stronger today with gusts of 40-60 mph possible. Locally flooding rainfall will continue to be a concern, especially where boundaries merge with locally heavy rainfall rates of 2-4 inches/hour possible. Rainfall will tapper off with loss of diurnal instability and in the wake of the departing short wave trough this evening, with dry conditions expected after midnight and mild, but muggy lows in the low to mid 70s. Some shallow ground fog and mist will be possible toward sunrise especially where recent heavy rainfall occurred. && .SHORT TERM... (Friday through Saturday night) Issued at 147 PM EDT Thu Jul 18 2024 High pressure will be centered to the east through Saturday, with troughing to the northwest. The location of the high will yield a flow from the south southwest. This will be an unsettled period, with convection initiating each afternoon as diurnal heating destabilizes the airmass. Convection will begin well inland, on the Gulf sea breeze, then build east across area. Storms will diminish in strength and coverage during the evening hours with loss of heating. With the expected flow, the each coast sea breeze will struggle to get past I95, so anticipate a secondary max in convection near the I95 corridor later in the afternoon, as inland storm converge with activity that develops on the east coast sea breeze. The high will begin to move more toward the east northeast Saturday night. This pattern change will be a significant change in the long term period. && .LONG TERM... (Sunday through next Thursday) Issued at 147 PM EDT Thu Jul 18 2024 The surface high pressure ridge will be located to the east northeast on Sunday, and will drift further to the northeast later in the period. With this pattern, the flow will largely be from the southeast. This will make the east coast sea breeze dominant this period. Therefore, convection is expected to initiate each afternoon due to diurnal heating, with a focus on the east coast sea breeze. As the sea breeze moves inland, convective chances over eastern zones will decrease. The 500mb pattern is largely stacked on the surface ridge, so not expecting the upper flow to push convection back east. So, best chances east early afternoon, then inland later in the afternoon, with convergence over I75 corridor from Gulf sea breeze. Convection will diminish during the evening hours with loss of heating. In general temperatures will trend a few degrees above normal this period. && .AVIATION... (18Z TAFS) Issued at 132 PM EDT Thu Jul 18 2024 TEMPO groups are included for all terminals over the next 3-4 hours due to TS with MVFR restrictions and wind gusts of 25 kts. As of 30-40 kts are possible today in stronger cells. Convection will press offshore of the local Atlantic coast and decrease in coverage from west to east through 22-01z. Lingering debris clouds overnight with dry conditions by 06z. Potential for MVFR due to shallow ground fog/mist after 07z 7/19 with a land breeze from the SW 2-4 kts at coastal terminals through 12z Friday. After daybreak, SW winds will increase with lingering debris clouds. Showers and isolated storms will approach GNV from the SW through 18z. && .MARINE... Issued at 147 PM EDT Thu Jul 18 2024 High pressure across south Florida will continue through Saturday with fronts lingering across south Georgia. This will continue prevailing southwest winds with a daily Atlantic coast sea breeze near the immediate coast and mainly afternoon and evening thunderstorms. The ridge will build north of the local waters early next week which will bring a prevailing southeasterly wind pattern across the local waters and increase morning and early afternoon rainfall potential with building combined seas. Rip Currents: Moderate rip current risk for all local beaches through Friday. The rip current risk increases early next week (Moderate to possibly High) as ESE winds develop over the near shore Atlantic waters and swells increase. && .PRELIMINARY POINT TEMPS/POPS...
