A pseudo-warm front lifted up the Florida peninsula through the day. This lift combined with daytime heating and increased moisture produced isolated strong to pulse severe storms along the sea breezes and boundary mergers.

Area Forecast Discussion National Weather Service Jacksonville FL 130 PM EDT Sat Sep 6 2025 ...New NEAR TERM, SHORT TERM, LONG TERM, AVIATION, MARINE, HYDROLOGY... .NEAR TERM... (Through Tonight) Issued at 127 PM EDT Sat Sep 6 2025 For the latest NE FL and SE GA Daily Key Messages please visit: https://www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf Moisture continues to lift northward along old frontal boundary into NE FL as PWATs have surged back around 2 inches and surface dewpoints have increased into the mid/upper 70s. The low level onshore flow and convergence has produced scattered showers along the I-95 corridor of coastal NE FL, which is still on track to shift inland with the East Coast sea breeze pushing across inland NE FL and meeting up with the Gulf Coast sea breeze front near the I-75 corridor and expect scattered to numerous showers along with embedded storms with locally heavy rainfall potential due to the increased moisture and slow storm motion at 10 mph or less. Convection over inland areas fades after sunset, leaving partly to mostly cloudy skies ahead of approaching front from the Northwest. Temps return to normal to above normal levels as the cloud cover will hold Min Temps in the lower 70s inland and mid to upper 70s along the Atlantic Coast. While some isolated showers will be possible through the night, the increasing low level moisture will likely lead to low stratus and patchy fog development in most inland areas, especially towards sunrise Sunday morning. && .SHORT TERM... (Sunday through Monday night) Issued at 127 PM EDT Sat Sep 6 2025 Higher layer moisture returns across the entirety of the area on Sunday, pooling ahead of another cold front approaching from the northwest. The front will cross the area Sunday Night, losing steam and stalling just south of the region on Monday. The higher moisture will result in more numerous showers and thunderstorms to return across the area Sunday, supported by both the lift of the lingering boundary to our south as well as the stronger boundary approaching from the north and west. With these two separate boundaries, hi-res guidance is in pretty good agreement in painting almost two separate areas of convective initiation, one being south of I-10 in Florida and a second over far interior GA with the daytime heating ahead of the front. The thermodynamic profile is not tremendously impressive across the region tomorrow, though some pockets of lingering dry air aloft combining with a bump up in effective shear with the front and upper level shortwave could be enough to yield some isolated stronger downbursts in the 40-50 mph range. Some activity may linger through at least the first half of the night as well with any remaining mesoscale boundaries as well as near the coast with the added nighttime coastal convergence along the front. Highs Sunday will be quite warm, in the low 90s for most inland and mid to upper 80s east of about the I-95 corridor. Lows in the 70-75 degree range will be common Sunday Night. Another northeast wind type of event sets up on Monday as high pressure tries to build into the region from the north and combines with offshore troughing associated with the nearly stalled front. Drier air advection aloft will not be as significant as with the previous event, and therefore expecting more numerous showers with some embedded thunderstorms to stream onshore Monday, especially over northeast FL, though moisture will certainly be plentiful enough across GA for at least a 20-40% chance of rain, especially closer to the coast/further south and east you go. Beach/coastal hazards such as higher rip current risk, elevated surf, and minor coastal flooding/beach erosion will be on the rise Monday associated with the strong offshore pressure gradient, which will also featuring breezy northeasterly winds in the 10-20G25-30 mph range across much of the area. As expected behind the front and with the breezy flow, high temps drop more below normal as low to mid 80s will be common. Some showers persist closer to the coast once again Monday Night with lows ranging from the upper 60s north and west to low to mid 70s south and east. && .LONG TERM... (Tuesday through next Saturday) Issued at 127 PM EDT Sat Sep 6 2025 No significant changes with the pattern expected through at least Wednesday as high pressure remains situated to the north of the region and the highest shower/t'storm chances remain over northeast FL and especially towards the coasts. Yet another frontal boundary moves towards and into the region by the Thursday/Friday time frame as long range guidance also suggests upper troughing/a cut off low may dip as far south as into the Gulf by Friday. This push both near the surface and aloft could bring either another surge of drier air into the region if we end up on the west side of the upper trough/low, or a feed of southwesterly Gulf moisture on the east side of the upper low/trough depending on how the pattern plays out. Either way, a more October-like amplified pattern looks to stick around through at least the next 7 days at this time. Temperatures trend near to slightly below normal for the long term period. && .AVIATION... (18Z TAFS) Issued at 127 PM EDT Sat Sep 6 2025 Widely scattered showers have developed across most of the NE FL TAF locations early this afternoon and plan to continue to handle these with VCSH and some brief MVFR CIGS, while SSI terminal should remain rain-free through tonight. Better organized convection is expected over inland NE FL near the I-75 corridor later this afternoon and still plan to include a PROB30 group at the GNV terminal for potential TSRA activity and lower MVFR CIGS/VSBYS from about 20-24Z time frame before rainfall chances decrease at all NE FL TAF sites after 00Z. Lingering mid/high level clouds expected through the overnight hours, then towards morning some boundary layer cooling and increase moisture levels is expected to lead to low level IFR/MVFR stratus and patchy MVFR vsbys, but Hi-Res model guidance continues to flip-flop on how much stratus coverage is expected, so will continue to trend downward into MVFR CIGS for all inland locations with TEMPO for IFR/LIFR conds at VQQ at the very least. Slow improving conditions through the Sunday morning hours and with diurnal heating expecting to add in VCSH at all NE FL TAF sites once again, along with lingering MVFR CIGS. && .MARINE... Issued at 127 PM EDT Sat Sep 6 2025 Onshore flow pattern continues as a weak warm front lifts north and stalls across the northeast Florida and coastal waters through tonight. A cold front will approach from the north as the stalled warm front morphs into a coastal trough on Sunday, increasing rain and thunderstorm chances over the waters. By Monday, the cold front reach the Georgia waters and send a surge of northeasterly winds southward down the coast. A period of small craft advisory conditions are possible Monday and Tuesday with gradually weakening northeasterly winds Wednesday onward. The front will continue toward south Florida through the week with a reinforcing front pushing towards the local waters by next weekend. Rip Currents: Moderate risk of rip currents through the weekend with light onshore flow and surf/breakers around 2 feet. Still expecting high risk of rip currents early next week with the upcoming surge of NE winds on Monday/Tuesday along with surf/breakers of at least 4-6 ft, with high surf headlines possible. && .HYDROLOGY... Issued at 127 PM EDT Sat Sep 6 2025 Surge of NE winds early next week will combine with already above normal astronomical tides due to the full moon and expect at least Minor Coastal Flooding during high tide cycles along the Atlantic Coastal beachfront locations as well as down the St. Johns River Basin. Still too early to determine these water levels will reach Moderate or greater flooding criteria next week. && .PRELIMINARY POINT TEMPS/POPS...
