-- Changed Discussion --
(00Z TAFS) Issued at 814 PM EDT Sat May 25 2024 A gust front will push across the SGJ terminal just after 00Z, with surface winds briefly shifting to northerly and increasing to 20-30 knots. Thunderstorm activity at SGJ will be possible towards 01Z through around 02Z, with MVFR conditions expected during a brief period of heavier downpours around 01Z. Anvil rainfall may linger at CRG and JAX in the wake of this convection through around 01Z, with VFR conditions otherwise prevailing at the regional terminals. The gust front will likely press southward towards the GNV terminal after 01Z, with a brief wind shift to northerly around 10 knots expected through around 02Z. VFR conditions should prevail at the regional terminals through at least 06Z. MVFR to IFR conditions are then expected to develop after 07Z through around sunrise at GNV and VQQ. VFR conditions should then prevail after 13Z. Outside of thunderstorm activity, variable winds of 5-10 knots through around 02Z will diminish overnight, with west-northwesterly surface winds of 5-10 knots resuming towards 14Z. The Atlantic sea breeze boundary will then push onshore before noon on Sunday, with surface winds shifting to easterly around 10 knots at SGJ after 16Z and southeasterly around 10 knots at SSI after 18Z. These onshore winds will then progress inland across the Duval County terminals by 20Z.

&& .SHORT TERM... (Sunday through Monday night) Issued at 228 PM EDT Sat May 25 2024 With an upper level ridge extending across the Gulf of Mexico, west- southwest steering flow will be in place, before a cold front begins to move in from the northwest late Monday. Hot and mostly dry conditions are expected, with a few showers possible as the Gulf coast sea breeze meets up with the Atlantic sea breeze along the east coast during the late afternoon into early evening on Sunday. Otherwise, the next chance of showers will be from late Monday afternoon into evening along the northern SE GA counties ahead of an incoming cold front nears the area. Temperatures will be on the warmer side, with Sunday seeing the warmer daytime temperatures. The highest temperatures will be focused toward the I-95 corridor as daytime temperatures will range in the low to mid 90s with heat index values around 100 degrees. && .LONG TERM... (Tuesday through next Saturday) Issued at 228 PM EDT Sat May 25 2024 On Tuesday a cold front will make its way the area, bringing scattered showers and storms to spread from SE GA and south to NE FL. The possibility for stronger storms Tuesday afternoon as some passing shortwaves aloft will bring some instability and additional lift to the area. By Wednesday the front will shift to central FL and eventually stalling over central FL, bringing chances of convection over the north central FL counties, with the potential for scattered showers and storms on Thursday and Friday. Temperatures will begin to `cool` a bit after the cold front`s passage. The drier air mass will bring a return of cool morning lows in the 60s for the latter half of next week. Highs will then range from the upper 80s in SE GA to the mid 90s in north-central FL. | && .MARINE... Issued at 228 PM EDT Sat May 25 2024 .MARINE...Tranquil boating conditions are expected through the weekend with high pressure in the area and prevailing offshore flow. Afternoon sea breeze development is anticipated each afternoon. The main concern will be the potential for thunderstorms mainly during the early evening hours tonight which could contain strong winds. Storm chances lessen Sunday and Monday before being renewed by an incoming cold front Tuesday. RIP CURRENTS...Moderate risk continues through Monday due to increased crowds at area beaches. Despite low surf (less than 2 feet) and weak swell, rip currents are still possible especially near piers and jetties. && .HYDROLOGY... Issued at 200 AM EDT Sat May 25 2024 Moderate river flooding due to `backwater` is forecast to begin next week from Thursday to Friday for the Santa Fe at Three Rivers Estates (lower Santa Fe basin). The Satilla River basin remains in Minor Flood stage and portions of the Suwannee are expected to rise into Minor Flood stage by early next week. && .PRELIMINARY POINT TEMPS/POPS...
