045 FXUS62 KTAE 291343 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 943 AM EDT Fri Aug 29 2025 ...New UPDATE... .UPDATE... Issued at 942 AM EDT Fri Aug 29 2025 The previous forecast appears to be on track. A transition to a soggier pattern is expected today with cloudy skies and passing showers and storms across the area. && .NEAR TERM... (Today and tonight) Issued at 207 AM EDT Fri Aug 29 2025 Much cooler day is on tap for the area as shortwave rounds a broad east coast upper level trough and interacts with a weak stationary front draped across the forecast area. Light stratiform rain was occuring this morning well to our west and northwest. This activity should drift east through the morning will likely bring light rain showers to our southeast Alabama and Panhandle counties through the early afternoon. Further east across the Florida Big Bend and southern Georgia uncertainty for rain and storms development is a little higher. This uncertainty likely comes from how cloud cover could influence the instability that will develop through the day. If cloud cover maintains to stay thin through the morning, it will increase confidence in the thunderstorm potential for the latter part of the day. Severe weather isn`t likely but some nuisance flooding can`t be ruled out in some of the stronger storms. As the shortwave pushes through by the evening, much of the activity should begin to diminish, but broad troughing still in place will lead to the potential for isolated showers continuing into the overnight hours. Another weak shortwave approaches the region from the west late tonight and into Saturday so more development of showers can`t be ruled out by early Saturday morning. && .SHORT TERM... (Saturday through Sunday night) Issued at 207 AM EDT Fri Aug 29 2025 A stationary front remains stalled over the area through this weekend, leading to a rather wet, unsettled weather pattern. PWATs will climb to around 1.9 to 2.1 inches across the area, which is around the 75-90th percentile for late August. As a few ripples in the mid-level flow round the base of the large eastern US trough and move across the area, weak frontal waves may develop at times, enhancing the rain chances. Given that we`re expecting periods of showers and storms, the timing of such waves is rather uncertain, but most of the activity will be during the daytime hours over land and overnight over the waters. Rain chances area wide are around 70- 90%. With an abundantly moist atmosphere, locally heavy rain will be possible in storms and some nuisance flooding will be possible in areas that receive multiple waves of rain. The boundary sags a bit southward on Sunday, keeping the highest rain chances (60-80%) in the Florida counties and 40-50% elsewhere. North of the boundary, northeast flow will prevail, which usually results in cooler-than-expected temperatures thanks to cloud cover lingering for a longer time. Thus, knocked Saturday`s highs down a couple of degrees into the upper 70s to lower 80s in southeast Alabama and southwest Georgia with low to mid 80s elsewhere. Sunday is pretty similar, though a couple degrees warmer. Lows both nights will be in the upper 60s to lower 70s. && .LONG TERM... (Monday through Thursday) Issued at 207 AM EDT Fri Aug 29 2025 The large trough over the eastern US nudges slightly eastward and our front sags ever so slightly southward. The front doesn`t make it very far south and gets stuck around Central Florida by mid week. High pressure does begin to build across the eastern US through mid- week. Progressively each day, rain chances will drop little by little, but the gradient of daily rain chances remains the same -- higher south, lower north. The next larger trough late next week will send a stronger cold front to our area, but its influence won`t be felt until after this period. Highs will slowly climb back up into the mid to upper 80s again through the course of the week. Lows will stay in the upper 60s to low 70s. && .AVIATION... (12Z TAFS) Issued at 624 AM EDT Fri Aug 29 2025 A mix of VFR/MVFR conditions is likely today as increasing clouds and rain chances move in through the morning and afternoon. Most activity through 18z should be without thunder, especially for western terminals at DHN/ECP. After 18z TSRA chances increase, especially at TLH/ABY/VLD. Most TSRA chances should decrease after 00z, but light rain showers will likely remain possible late into the TAF period along with potential redevelopment of more widespread MVFR/IFR conditions as low ceilings develop. && .MARINE... Issued at 207 AM EDT Fri Aug 29 2025 A stationary front will waver over the marine area through the weekend bringing periods of showers and thunderstorms. Gentle breezes will continue through the weekend with seas around 1 to 2 feet. To the north of the front, winds will be northeasterly, but south of the front, winds will be westerly to southwesterly. The front dips south of the marine area Sunday night into early next week. High pressure builds in over the eastern US, tightening the pressure gradient over the waters. Thus, winds will become moderate to fresh out of the northeast. Cautionary conditions are possible Sunday and Monday nights with seas building to 2 to 3 feet. && .FIRE WEATHER... Issued at 207 AM EDT Fri Aug 29 2025 Increasingly moist air mass is expected today and into this weekend with the chance for wetting rains peaking on Saturday across much of the region. Wet conditions continue into Sunday mainly south of I- 10. Easterly transport winds expected on Friday with directions becoming more variable through the weekend depending on the evolution of the frontal system. Dispersions will likely remain low through the next several days. && .HYDROLOGY... Issued at 207 AM EDT Fri Aug 29 2025 Models are still struggling a bit with the placement of the heavy rainfall over the weekend. However, the trend is for the bulk of Friday and Saturday`s rainfall to be over the land areas, while Sunday onward, the rain is more near the coast and offshore. Models do tend to struggle with the placement of stationary fronts, particularly with how far north the front can make it. Areas closest to the front will have the heaviest rain potential. Most likely, areas north of I-10 will see about 1 inch of rain on average, with areas south of I-10 seeing about 1-3 inches as an areal average. But, reasonable worst case scenario (10% chance of seeing more than these totals) through the weekend yields isolated pockets of 3 to 6 inches. This would cause nuisance-type flooding of poor drainage, low-lying, or urban areas. These higher-end totals would be more confined to areas along and south of I-10. Most of the rivers can take several inches of rain with no problem, but the most vulnerable river would be the Sopchoppy which just fell out of action stage about 30 hours ago. It would take about 4 inches of rain to bring it back to action stage and about 6 inches to bring to minor flood. The St. Marks at Newport has also been elevated lately, and it would take about 2-3 inches to bring the river back into action stage. && .SPOTTER INFORMATION STATEMENT...
