The episode as NWS JAX wrote it up.
Sea breeze storms were more limited given drier mid and upper level air over the region, but a few strong to severe storms formed during the evening hours across inland areas.
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 13, 12:58 PM EST, 6 hours 32 minutes earlier.
Area Forecast Discussion National Weather Service Jacksonville FL 158 PM EDT SAT AUG 13 2016 .NEAR TERM...This afternoon through Sunday... Both sea breezes were developed and advancing inland this afternoon with NNW to SSE oriented cloud streaks indicative of the low level ridge axis just north of the local area and prevailing steering flow pushing convection to the NNW. A few cells were starting to pop across Flagler and St. Johns counties this hour...and anticipate additional initiation farther west across NE Florida through the afternoon. Area of enhanced cumulus near our western Ga zones will also start to precipitate soon. Through the afternoon and into the early evening...sea breeze and convective outflow forcing will focus across the interior of the CWA with outflow/boundary mergers between the I-75 and Highway 301 corridors with clearing across our zones generally east of the St. Johns River basin into the evening. Drier and cooler mid/upper level air over the area on the WNW side of an upper level low retrograding across S Fl will keep convection scattered in coverage...but could also enhance downburst potential with evaporative cooling and steeper lapse rates present in stronger cells. The main convective concerns will be strong gusty winds of 40-50 mph and excessive lightning across interior locations late this afternoon and evening. High temps will top out in the low/mid 90s inland with the coast already cooling into the mid 80s with the east coast sea breeze pushing inland. Tonight convective will fade in coverage and intensity after sunset across our western zones with clearing skies after midnight. Could see some patchy fog and low stratus form inland across the Suwannee River Valley after midnight as low temps fall into the low/mid 70s inland to upper 70s/near 80 along the Atlantic coast and St. Johns River basin. Sunday the upper level low will be across the eastern Gulf with a deeper and more moist southerly upper level flow over the area on the eastern side of the vortex. In addition to cooler temps and a moisture surge from the south...increasing PVA rotating northward around the low will sweep across our Fl zones during peak heating...then progress northward across our SE Ga zones into the evening. In the lower levels a stronger easterly flow is expected...which will push the east coast sea breeze inland a bit faster than today and focus the highest rain chances across our inland zones toward the I-75 corridor where sea breezes/outflows will converge as upper level dynamical support pivots above and low level instability is maximized. In total...appears convective ingredients will be more favorable for strong to isolated severe storms Sunday afternoon across our inland zones which could produce strong downbursts. Temperatures will remain near recent values with highs in the low/mid 90s inland to upper 80s coast. .SHORT TERM /Monday through Tuesday Night/... High pressure at surface and aloft strengthen somewhat while moving very little during this period...enhancing onshore component of low-level flow. This should continue pattern with better rainfall chances over the interior counties compared to coastal counties. Consensus guidance following this with chance POP values well inland...slight chance values closer to the coast due to lesser expected coverage. High temps both days will range from upper 80s coast to around 90 i-95 corridor and 90-95 range further inland. .LONG TERM...Wednesday Through Saturday/... Little change in surface/upper pattern until Thursday...as shortwave trough moves eastward over mid-Atlantic region Thursday/Friday...causing upper ridge over our area to weaken and shift south/east..leading to a more southerly surface flow over our area Fri/Sat. This will support better rain chances for coastal counties. Near normal temperatures are forecast for coastal counties...slightly above normal further inland. && .AVIATION... Prevailing VFR conditions with restrictions possible this afternoon and evening in scattered convection at inland terminals. Atlantic coast sea breeze was west of SGJ...SSI and soon CRG with TS not advertised...while VCTS was still included at the other terminals through this evening. Precip will fade inland with a NNW drift with clearing skies overnight. SREF model guidance suggested a low potential for some patchy shallow ground fog and low stratus mainly near and west of the I-75 corridor Sunday morning but confidence not high enough at this time to include in forecast for GNV. && .MARINE... Surface high pressure will dominate northeast of the local waters which will continue a prevailing southeast flow over the local waters. Daytime sea breezes will increase magnitudes to near 15 kts at times along the coast with nocturnal land breezes shifting the winds offshore early in the morning. Combined seas will generally range below 3 ft. Rip Currents: Low risk today and Sunday. && .PRELIMINARY POINT TEMPS/POPS...
