194 FXUS62 KTAE 301046 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 646 AM EDT Wed Sep 30 2026 ...New AVIATION... .KEY MESSAGES... Issued at 644 AM EDT Wed Sep 30 2026 - An unseasonably hot and humid air mass is forecast to return by Thursday and continue into the weekend with heat indices reaching the mid 90s to lower 100s. - Rain chances are forecast to increase substantially this weekend with several rounds of showers and storms possible across the region. A Marginal Risk (level 1 of 4) for excessive rainfall is in effect for parts of Southeast Alabama and the Florida Panhandle for Friday and Saturday. && .SHORT TERM AND LONG TERM... (Today through Tuesday) Issued at 146 AM EDT Wed Sep 30 2026 Surface high pressure across the Mid-Atlantic States continues to move offshore. This return to south-southeasterly flow will allow moisture advection to ramp up across the region with PWATs surging to 2 to 2.5 inches by this weekend and remaining fairly intact throughout most of next week. An approaching cold front looks to cause widespread showers and storms beginning Friday and lasting through passage on Monday. The front is expected to get hung up across our Gulf waters leading to continued unsettled weather next week as high PWATs drive what`s likely to be continuous overrunning precip as northeast flow prevails behind the front. This multi-day rain event has the potential to pile decent rainfall accumulations across our coastal counties. The Weather Prediction Center is forecasting 4 to 7 inches along the immediate coastline and around 2 to 4 inches across inland FL Panhandle and SE Alabama. It should be noted that some model guidance is depicting the potential to see around 7 to 10 inches along the immediate coastline, we`ll need to monitor this situation closely over the coming days. Otherwise, expect temps to remain elevated through Friday before precip chances really ramp up this weekend. Generally, daytime highs look to be in the upper 80s to low 90s with a dip this weekend into the 80s with a further dip by next Tuesday into the 70s. Overnight generally look to remain in the upper 60s to low 70s throughout most of the period, it`s not until Tuesday morning that lows dip into the mid 60s. && .AVIATION... (12Z TAFS) Issued at 644 AM EDT Wed Sep 30 2026 Prevailing VFR conds expected this TAF cycle. The main exception is invof VLD where a brief window of reduced vsbys from patchy fog is possible until about 13Z. Winds increase up to 10 kts out of the SE late this morning thru the aftn with isolated convection primarily near the coast. The potential, albeit low, remains for showers to encroach on ECP/TLH/VLD, so have VCSH holds. A t-storm or two still cannot be ruled out near ECP between 18Z & 0Z. -TSRA. && .MARINE...
