235 FXUS62 KJAX 271720 AFDJAX Area Forecast Discussion National Weather Service Jacksonville FL 120 PM EDT Fri Jun 27 2025 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... (Through Tonight) Issued at 117 PM EDT Fri Jun 27 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 Southerly flow around the mid/upper level low pressure to the west of the region will continue to increase moisture levels with PWATs pushing close to 2 inches this afternoon. This combined with surface heating into the lower 90s and inland moving Gulf/Atlantic sea breezes will result in scattered to numerous showers and storms between the US 301 and I-75 corridors. Cooler air aloft will continue to support strong updrafts and isolated severe storms with damaging downburst winds and marginally severe hail at times over inland areas. A slow shift towards Southwest flow through the evening hours will continue this convection through sunset with some of the weakening storms actually drifting back towards the East Coast through midnight, while the rest of the strong storm activity will shift into inland SE GA as the Gulf/Atlantic sea breeze merger continues to zipper towards the NW. Most of the convection should end around midnight with fair skies and mild temps in the 70s overnight, along with some patchy inland fog possible towards morning in areas that received rainfall this afternoon. In addition to this, the increasing low level SW flow will start convection over the NE Gulf/Big Bend region towards morning, and a few of this showers/possible isolated storms may spill into the I-75 corridor near GNV/OCF around sunrise as well. && .SHORT TERM... (Saturday through Sunday night) Issued at 117 PM EDT Fri Jun 27 2025 Surface high pressure will be centered to the east this period, with ridge extending across central FL. The resulting low level flow will prevail from the southwest. This will allow the Gulf sea breeze to prevail, with it colliding with the east coast sea breeze west of I95. With ample moisture, and diurnal heating providing instability, numerous afternoon and evening thunderstorms can be expected each day this weekend. The greatest chance for storms will be over eastern counties due to the sea breeze interactions. The convection will diminish during the evening hours, with mainly dry overnights forecast. Temperatures will trend a little above normal this period. && .LONG TERM... (Monday through next Friday) Issued at 117 PM EDT Fri Jun 27 2025 Surface high pressure will remain centered to the east of the region this period, with ridging extending across central FL. A weak trough will develop over the southeastern US. A trough aloft will also develop over the southeastern US this period. Above average precipitation chances are expected this period, with mainly afternoon and evening thunderstorms each day. Temperatures will trend near to a little above average through the week. && .AVIATION... (18Z TAFS) Issued at 1219 PM EDT Fri Jun 27 2025 Inland moving sea breezes from both coasts will still support best storm chances at GNV/VQQ/JAX and will continue TEMPO groups for potential gusty wind/MVFR CIGS/VSBYS with storm activity, likely in the 18-22Z time frame at JAX, 19-23Z time frame at VQQ and 20-24Z time frame at GNV, lesser chances exist the closer to the Atlantic Coast and will leave PROB30 at CRG/SGJ, and just VCSH at SSI through the evening hours. Left over VFR convective debris through the overnight hours, with fairly low fog chances, so will likely only include the usual MVFR fog at VQQ from 07-11Z. Shower activity will kick off towards the end of the upcoming TAF period and will likely add VCSH to all TAF sites after 15Z Saturday. && .MARINE... Issued at 117 PM EDT Fri Jun 27 2025 Atlantic high pressure will extend its axis westward across the Florida peninsula through early next week as surface troughing gradually sharpens over the southeastern states, creating a prevailing offshore wind flow. Afternoon and evening showers and thunderstorms will likely push eastward across our local waters each day, with daily strong storm potential. Daily afternoon into evening south-southeasterly wind surges expected along the nearshore waters as the Atlantic sea breeze shifts inland. Winds and seas are expected to remain below SCA criteria through this weekend and into early next week. Rip Currents: Low to Moderate Rip Current Risk will continue through the upcoming weekend with surf/breakers in the 1-2 ft range, as a general southwest flow is expected, along with daily sea breeze in the surf zone during the afternoon/evening hours. && .PRELIMINARY POINT TEMPS/POPS...
