380 FXUS62 KTAE 202341 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 741 PM EDT Sun Sep 20 2026 ...New UPDATE, AVIATION... .KEY MESSAGES... Issued at 730 PM EDT Sun Sep 20 2026 - Unseasonably warm temperatures will continue through the next couple days. Highs will range from the low to middle 90s across inland areas. - Rain chances continue through Monday. Afternoon thunderstorms this evening, and possibly again tomorrow, may have gusty winds and small hail, in addition to lightning. && .UPDATE... Issued at 730 PM EDT Sun Sep 20 2026 The main update to the forecast this evening was to increase POPs across much of the area, especially across the Florida Panhandle, for the next few hours. A few clusters of showers and storms, a few strong to severe, continue across portions of southeastern Alabama and the Florida Panhandle. Some of these thunderstorms have had descending hail cores that have produced very locally damaging winds across portions of SE Alabama and do expect them to continue for a few hours as this cluster of storms moves through the Florida Panhandle. Elsewhere, a few showers and rumbles of thunder linger for southwestern Georgia and the Florida Big Bend, but these should remain sub- severe. && .SHORT TERM AND LONG TERM... (This Evening through Saturday) Issued at 306 PM EDT Sun Sep 20 2026 The closed upper low over the eastern Gulf will continue spinning, gradually moving west through the next day or so, providing the region with enough forcing for ascent to produce unsettled weather. On Tuesday, a shortwave moving across the Tennessee Valley will pull this upper low northeast and away it goes, taking rain chances with it. Increasingly drier northeast air begins to filter into the region beginning on Wednesday and persisting through the weekend, keeping rain chances near or below 10%. Expect daytime highs generally in the low to mid 90s through Wednesday, Thursday through Saturday highs will look to be in the mid to upper 80s. Overnight lows follow a similar pattern with lows generally in the low to mid 70s through Thursday morning, dropping into the mid to upper 60s Friday and Saturday. && .AVIATION... (00Z TAFS) Issued at 730 PM EDT Sun Sep 20 2026 Clusters of showers and storms are forecast to near KECP in the next few hours, so have included TEMPO groups for TSRA to account for that potential. Elsewhere, light to moderate rain and an occasional lightning strike remains possible the next few hours before most of the rain/storms wind down by 04Z/05Z or so. VFR conditions are generally forecast to prevail through the night, although a brief period of MVFR to IFR ceilings are possible at KVLD, with a lesser chance at KTLH and KABY. Hi-res guidance suggests the best opportunity for showers/storms Monday afternoon to be near KVLD, KTLH, and KECP, so have included PROB30s for those sites with this TAF issuance. Confidence wasn`t quite high enough to include showers/storms for KABY and KDHN with this TAF package, but it`s something we`ll monitor in future packages. && .MARINE... Issued at 306 PM EDT Sun Sep 20 2026 Gentle to moderate east to northeast breezes expected through midweek with high pressure generally north of the waters. Within the seabreeze zone, moderate onshore flow will develop each afternoon into the evening before switching offshore during the overnight hours. Isolated showers and thunderstorms are expected through midweek as well. A cold front is slated to move through the Gulf waters later this week. Expect moderate to fresh northeast winds to accompany the front towards next weekend. && .FIRE WEATHER... Issued at 306 PM EDT Sun Sep 20 2026 High pressure remains anchored to our north continuing northeast transport winds into early this week. Isolated to scattered showers and storms will develop each afternoon into the evening hours with the better coverage along and south of I-10 associated with the seabreeze. Erratic and gusty winds, in addition to lightning, are the main concerns. Afternoon minRHs will fall into the mid-40s to mid-50s over the next few days. Heat indices the next few days will be between 96-104F during the afternoon hours. Low dispersions today will be located from I-75 south into the Florida Big Bend. && .HYDROLOGY... Issued at 306 PM EDT Sun Sep 20 2026 Generally around an inch of rainfall is expected over the next week from afternoon showers and thunderstorms. Isolated higher amounts could be possible under any downpours. There are currently no riverine flooding concerns. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
