001 FXUS62 KTAE 250150 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 850 PM EST Mon Nov 24 2025 ...New UPDATE... .KEY MESSAGES... Issued at 847 PM EST Mon Nov 24 2025 - Another round of widespread patchy to dense fog impacting travel is likely Tuesday morning. - A Marginal risk (level 1 out of 5) of severe weather is in effect Tuesday night/Wednesday morning for our central and western counties. Associated total rainfall amounts are unlikely to impact drought conditions. - High confidence in below average temperatures during the second half of the week, with low temperatures near freezing on Friday and Saturday mornings. - Fire Weather concerns increase Thanksgiving Day and Friday with low relative humidity and ongoing drought conditions. && .UPDATE... Issued at 850 PM EST Mon Nov 24 2025 The forecast is in good shape, so no updates are needed. Fog and low clouds are already forming over Wakulla and Franklin Counties. This patch will grow and spread north-northwest for the rest of this evening into the overnight. This is already well reflected in the forecast. For those driving on Tuesday morning, allow extra time. Slow down, especially when approaching intersections and bus stops. Fog will quickly lift off the ground about 3 hours after sunrise. && .SHORT TERM... (This Evening through Tuesday) Issued at 203 PM EST Mon Nov 24 2025 Another round of patchy to dense fog looks to impact much of the region tonight and tomorrow morning. Surface winds will be oriented more out of the SE through the night which may favor our central and western counties for higher probabilities of dense fog coverage which is in line with some of our hi-res guidance. Still, with low confidence in the exact spatial distribution of fog, fog was put in the forecast for most of the region tonight. There is a low-end chance for some low-topped showers tomorrow morning in our extreme western counties in a zone of enhanced warm air advection ahead of our next system. && .LONG TERM... (Tuesday night through next Sunday) Issued at 203 PM EST Mon Nov 24 2025 Tuesday night/Wednesday morning sees the arrival of an approaching front that will usher in a pattern change away from the warm and moist weather of the past few days and into a cool and dry pattern. Ahead of the front, a band of showers and thunderstorms will sweep through the area. Moderate deep-layer shear and curved hodographs in the warm sector indicate at least a low-end severe threat - limited primarily by the weak forcing as the parent shortwave weakens and shoots NE. Any severe weather will likely be confined to our northwestern counties and will be somewhat dependent on the magnitude of surface heating that is able to occur ahead of the front. For now, the Storm Prediction Center has placed much of our central and western regions in a Marginal (level 1 out of 5) risk for severe weather. Regardless of severe weather, associated rain totals are meager at best, with mean QPF around 0.1-0.25" across the region, and even the 90th percentile rainfall totals struggling to exceed 0.75-1". In all, while any rainfall is welcome, this system will not significantly impact the current drought conditions. Temperatures and moisture plummet following frontal passage on Wednesday. Thanksgiving day will be fairly cool, with highs in the low 60s/high 50s, and lows dropping well into the 30s Thursday night/Friday morning. Fire weather conditions will quickly become a concern with this setup as dewpoints drop into the 20s on Thursday and into mid-teens on Friday before beginning to increase this weekend. With some elevated gradient winds as a ridge sets in to our north, fire concerns will be maximized on Thursday and Friday as it overlaps with widespread low-critical RHs and very dry fuels thanks to the ongoing drought. Please make sure to exercise caution and listen to local officials on fire guidelines - especially if you are planning on any outdoor cooking or flames during the holidays. Our next chance for rain is late this weekend as a low pressure system may develop and push a front through our area - although confidence is low at this point due to varying solutions in model guidance. && .AVIATION... (00Z TAFS) Issued at 640 PM EST Mon Nov 24 2025 At 2330z, satellite imagery and web cams showed low clouds along the coast south and southwest of TLH, with cigs under 010. These clouds will spread north-northwest across TLH this evening. Cigs will then lower for the rest of the evening, until it lowers to the ground and becomes fog that will linger until a few hours after sunrise. These low clouds will continue to spread northwest this evening, reaching DHN. Despite the stirring effect of some wind, DHN`s hilltop location should be favorable for intersecting the low cloud deck. Further south, ECP will be near the left edge of the stratus deck spreading NW from TLH to DHN. With lower confidence, have not indicated dense fog in the forecast at ECP for now. ABY may be in a more favorable zone between low stratus to the west and low stratus to the east. For VLD, we will be watching low stratus gather this evening over southeast Georgia, expanding west to near the terminal overnight. All terminals will see rapid improvement in visibility 3 hours after sunrise. Low clouds will linger until midday, then scatter out during the afternoon. && .MARINE... Issued at 203 PM EST Mon Nov 24 2025 Light to moderate southeasterly to southerly winds develop tonight and linger through Wednesday morning ahead of a cold front. A few showers and storms are forecast to move through as the front moves through Tuesday night into Wednesday. Winds turn northerly and increase to Advisory levels late Wednesday night into Thursday. Advisory level winds are forecast more often than not Friday and Saturday as winds clock around to the east by Saturday. && .FIRE WEATHER... Issued at 203 PM EST Mon Nov 24 2025 Southerly flow ahead of an advancing cold front develops Tuesday. A few showers are forecast Tuesday afternoon for the western Florida Panhandle and western portions of southeastern Alabama ahead of the cold front. Chances for a wetting rain remain medium to high (50-70 percent) for a line along and west of Panama City, FL to Albany, GA and low to medium (10-50 percent) east of that line with lower chances the more south and east you go. Much drier air filters in behind the front for Thanksgiving Day and Friday, sending MinRH values to between 20 to 30 percent Thursday and 15 to 25 percent Friday. There remains a low (10 percent) chance of winds exceeding 15 mph Thursday, so there is the potential for Critical Fire Weather conditions on Thanksgiving; of course, that largely depends on how much rain there is Tuesday night into Wednesday and where it falls. && .HYDROLOGY... Issued at 203 PM EST Mon Nov 24 2025 Rainfall amounts are generally forecast to be less than 0.50" across the region with the most forecast to fall north and west of a line from Albany, GA and Panama City, FL. There is a very low (10 percent) chance for 1" or more of across portions of southeast Alabama and the western Florida Panhandle. Rain chances and amounts dwindle east of that line to less than 0.10". Another opportunity for rain arrives late in the weekend into early next week. No flooding is anticipated from any of these rain chances/totals. As of Thursday, November 19, 2025, the US Drought Monitor now has the area around the Florida-Georgia state line outlined in Exceptional Drought (D4), which is the highest category on the drought monitor. This is the first time since the 2011-2012 winter that any part of our area of responsibility has been outlined in Exceptional Drought.
