525 FXUS62 KTAE 012303 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 703 PM EDT Wed May 1 2024 ...New AVIATION... .NEAR TERM... (Through Thursday) Issued at 316 PM EDT Wed May 1 2024 The Sea breeze is currently making its way inland across the eastern Florida Panhandle and Big Bend with isolated showers and a few lightning strikes developing. Coverage should remain rather sparse and will quickly fade after sunset. Another round of fog, possibly locally dense, is expected tonight, mostly across the Florida Panhandle and Big Bend, though it could nudge its way into southern Alabama and southern Georgia. Lows tonight will be in the mid-60s. Generally southeasterly flow is expected tomorrow, though another sea breeze may set up across the eastern Big Bend. This could collide with the Atlantic sea breeze late in the afternoon, yielding scattered showers and storms near the Suwannee River, eastern Big Bend, and I-75 corridor. Looking at forecast soundings, dry air aloft and steep low-level lapse rates could result in some gusty winds with the strongest storms. DCAPE values peak around 1000 J/kg in the eastern Big Bend, which usually tends to be favorable for some stronger winds during these summertime sea breeze scenarios. Elsewhere, showers and storms are currently not expected. Highs tomorrow afternoon will peak near 90 away from the coast with mid- 80s near the beaches. && .SHORT AND LONG TERM... (Thursday night through Tuesday) Issued at 316 PM EDT Wed May 1 2024 High pressure will sit off the southeast Atlantic seaboard through the weekend which will lead to the chance for some seabreeze convection. In addition to that, a couple of shortwaves pass just to our north. This could enhance shower and thunderstorm development over the weekend. The best chances look to be on Saturday where we could see isolated to scattered storms in SE AL and the FL counties but up in SW GA they may be more scatter to widespread. On Sunday, the disturbance is a favors a more northern track, keeping the best chances for pop along and then within several counties of the I-75 corridor for SW GA. Monday and Tuesday, conditions should dry out in terms of precip. Expect daytime highs generally in the upper 80s to low 90s with overnight lows generally in the low to mid 60s. && .AVIATION... (00Z TAFS) Issued at 702 PM EDT Wed May 1 2024 Isolated pop-up showers and thunderstorms will continue this evening around all terminals except for ABY. The convection will end by 01z. Overnight, another round of fog is expected to affect all terminals, except ABY. ECP and TLH terminals will be impacted by possibly dense fog, resulting in LIFR vsbys (and VLIFR for TLH with 1/4SM vsbys) between 08z and 13z Thursday morning. The DHN terminal will be along the edge of the fog bank where it may be affected with potentially IFR conditions. The ABY terminal may fall to MVFR cigs, but is expected to remain VFR as it will likely be too far north for the fog to settle in. The VLD terminal is forecast to fall to MVFR but, confidence is low given persistence trends which would bring cigs down to LIFR. Conditions are expected to return to VFR by mid morning. && .MARINE... Issued at 316 PM EDT Wed May 1 2024 High pressure off the Atlantic will lead to tranquil boating conditions through the period. Light winds, generally out of the southeast, are expected with seas around 1 to 2 feet into the weekend. There may be a small chance of showers and thunderstorms Saturday and Sunday morning for waters east of Apalachicola. && .FIRE WEATHER... Issued at 316 PM EDT Wed May 1 2024 Generally southeasterly to southerly transport winds around 10 mph are expected each day across the area. Daily sea breeze pattern will promote winds becoming more southerly during the afternoon, especially over the Florida zones. This combined with high mixing heights during the afternoon will yield good to locally excellent dispersions each afternoon. Isolated showers and thunderstorms will be possible Thursday afternoon near the Suwannee River and I-75 corridor and Friday afternoon across southwest Georgia. Rain chances increase on Saturday across the entire forecast area with the greatest rain chances over southwest Georgia. && .HYDROLOGY... Issued at 316 PM EDT Wed May 1 2024 No changes to the forecast as minor river flooding remains on the Lower Suwannee this afternoon and should fall below minor flood stage in the next day or so. With rainfall amounts staying below 0.50 inches the next few days, no additional riverine flooding is expected. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
