078 FXUS62 KTAE 151949 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 249 PM EST Sat Nov 15 2025 ...New SHORT TERM, LONG TERM, AVIATION, MARINE, FIRE WEATHER, HYDROLOGY... .KEY MESSAGES... Issued at 1223 PM EST Sat Nov 15 2025 - The probability for Dense Fog impacting Sunday morning travel is at least 50% along and south of I-10 FL, the Flint River Valley, and near the Suwanee Valley FL. - Elevated Fire Weather Concerns this evening over portions of Southwest Georgia and again Monday afternoon over portions of Southeast Alabama and Southwest Georgia for critically low Relative Humidity. - Small Craft Operators Should Exercise Caution tonight through Sunday, and there is a 60% chance of a High Rip Current Risk along Walton, Bay, and West-facing Gulf County beaches Sunday. && .SHORT TERM... (This Evening through Sunday) Issued at 1223 PM EST Sat Nov 15 2025 A pleasant and dry Saturday afternoon and evening with above average temperatures well into the 70s away from the coast. The dry air mass with RH values in the lower to middle 20s (closer to the 10th percentile of guidance), mainly from the Flint River Valley eastward in Southwest GA, is contributing to elevated fire weather concerns through this evening with easy fire starts possible. Moving on into tonight and Sunday morning, the main weather concern will be the potential for fog, some of which could be dense. While a very moist air mass will be in place, guidance is all over the place with respect to the placement of fog, 1) Due to a low-level jet w/elevated surface winds, especially northwest of the FL Big Bend and 2) Uncertainty in how stout the low-level inversion becomes which will influence strength of the surface winds. Fog developing after midnight could be intermittent (touch and go) given elevated winds, but where the surface wind relaxes most, dense fog will be possible. Highest probability (AOA 50%) for Dense Fog impacting Sunday morning travel until ~9 AM ET/8 AM CT is along and south of I-10 FL, Flint River Valley, and near the Suwanee Valley FL. Another pleasant day is in store Sunday with breezy west winds and continued above average temperatures in advance of a dry cold front. Wind gusts from late morning through the afternoon will be around 20 mph. This will lead to brisk onshore flow along the Emerald and portions of the Forgotten Coasts, with a 60% chance of a High Rip Current Risk along Walton, Bay, and West-facing Gulf County beaches Sunday. && .LONG TERM... (Sunday night through next Friday) Issued at 1223 PM EST Sat Nov 15 2025 Above average temperatures are in store for the work week with dry weather until the next chance of rain on Friday. Winds are expected to be light after a dry cold frontal passage Sunday night, and with a moist air mass in place mainly across the FL Counties Monday morning, additional fog is possible in the Eastern Panhandle and Big Bend. A very dry air mass will again be in place by Monday afternoon with dew points closer to the 10th percentile of guidance, decreasing into upper 20s/ lower 30s moving northward into Southeast AL and especially Southwest GA. This would again result in elevated fire weather concerns over portions of Southeast Alabama and Southwest Georgia for critically low Relative Humidity. The next chance of rain is Friday into Saturday, with ECENS and its more robust mid-level shortwave over TN Valley more bullish compared to the GEFS. PoPs of 20-40% suffice for now, highest northwest of the FL Big Bend, with rainfall amounts/drought implications discussed further in the Hydrology section at the bottom. Cannot rule out strong storms, with a small number of ensembles hinting at this, as Bulk Shear increases to around 30 kt and at least some surface-based instability, generally west of the Apalachicola and Flint Rivers. Otherwise, Thursday and Friday should feature breezy Southerly winds with gusts around 20 to 25 mph possible. && .AVIATION... (18Z TAFS) Issued at 1223 PM EST Sat Nov 15 2025 VFR conditions are generally expected until midnight. Throughout the overnight hours, patchy to areas of fog are likely over the Florida Panhandle and Big Bend, along with portions of southern Georgia. MVFR to IFR vsbys could impact terminals TLH and VLD, there`s currently medium confidence in restrictions. To the north, across DHN and ABY a cold front approaches which will result in increasing low level wind shear during the overnight hours. After sunrise tomorrow morning, fog will disperse and low level wind shear will be reduced as the atmosphere mixes out. && .MARINE... Issued at 1223 PM EST Sat Nov 15 2025 Tranquil boating conditions this evening, before westerly winds increase overnight and continue into Sunday in the 15 to 20 knot range, with seas building 2 to 3 feet. Winds begin to subside in the wake of a cold frontal passage Sunday night, but seas remain elevated until slowly subsiding to 1 to 2 feet on Monday. As such, Small craft operators should exercise caution beginning tonight to the west of Apalachicola, then east of Apalachicola on Sunday into Sunday night. As a moist and relatively warm air mass moves over the cooler waters of Apalachee Bay late Sunday into early Monday, patchy maritime fog is possible. More tranquil boating conditions return by late Monday through Wednesday as high pressure settles over the waters. As the high center moves east and a low center approaches the Mississippi Valley, southeasterly winds will increase by Thursday, with the potential for Small Craft Advisory conditions increasing. && .FIRE WEATHER... Issued at 1223 PM EST Sat Nov 15 2025 Brisk westerly transport winds on Sunday in advance of a dry cold front will lead to dispersions on the higher side, but not expected to be critically high, along with much higher afternoon RH compared to the past couple of days (generally in the 50s). The dry cold frontal passage Sunday night will usher in a much drier air mass for Monday afternoon, with RH tanking to around 20% moving northward of the FL border further into Southeast AL and Southwest GA, but rising through the 30s and 40s in the FL Counties southward toward the Gulf coast. Northerly 20 ft winds will be light, so the main concern will be easier fire starts given the low RH, leading to elevated fire weather conditions on Monday afternoon and evening. Given the light northerly transport winds on Monday afternoon, dispersions will be fair at best, and cannot rule out some pockets of lower values. On Tuesday, RH values may dip into the 30s again in Southeast AL and Southwest GA, but are expected to remain above critical levels at this time. Dispersions may improve to fair by Tuesday afternoon. Looking ahead, the next chance of wetting rains is Friday into Saturday, with highest chances generally west of the Apalachicola and Flint Rivers. But the chance for this precipitation to put a dent in the ongoing drought is low. && .HYDROLOGY... Issued at 1223 PM EST Sat Nov 15 2025 Much of the region remains in Severe (D2) to Extreme (D3) drought according to the latest US Drought Monitor. This is resulting in streamflows of below to much below normal across much of the area for this time of year. Despite increased rainfall chances Friday into Saturday, especially northwest of the Apalachicola and Flint Rivers, forecast amounts are not expected to put a dent in the drought unless they reach the 90th percentile of the ensembles, which is only around a 20% chance. && .SPOTTER INFORMATION STATEMENT...
