296 FXUS62 KTAE 310541 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 141 AM EDT Sun Aug 31 2025 ...New NEAR TERM, SHORT TERM, LONG TERM, AVIATION, MARINE, FIRE WEATHER, HYDROLOGY... .NEAR TERM... (Today and tonight) Issued at 122 AM EDT Sun Aug 31 2025 Stationary boundary is draped from north central Florida westward through our Gulf waters. Surface high pressure located in the northeast US with ridging riding down the Appalachians will induce northeast surface winds across the Tri-State region. This will usher in drier air through the northern half of our CWA, hold the front at bay from moving much at all, and pin the seabreeze this afternoon closer to the coast. With higher PWATs located south of I10 and the seabreeze pinned, have better rain chances (30-50%) relegated in coastal sections, southeast Big Bend and extreme southern Georgia if convection moves that far northward. Otherwise, mostly sunny skies are on tap, northeast winds of 10-15 mph and highs in the mid to upper 80s. Tonight, lows will fall into the mid to upper 60s. && .SHORT AND LONG TERM... (Monday through Saturday) Issued at 122 AM EDT Sun Aug 31 2025 A broad upper level trough will prevail over the eastern half of the country through much of the upcoming week. At the surface, an axis of surface high pressure will extend down the eastern portion of the Appalachians through much of the upcoming week and give much of the forecast area broad northeasterly flow. Light south and southwesterly flow develops late in the week and temperatures will warm. The upcoming week will generally be dry given the lack of appreciable moisture for shower/storm development. The broad frontal system that lingered over the forecast area through the weekend will continue to slowly push south on Labor Day as the axis of the surface high noses south into the forecast area. Any rain showers will likely be confined well to our south with only portions of the southeast Big Bend possibly seeing rain on Monday as these locations reside closer to the old frontal boundary. Tuesday and Wednesday will continue to see northeasterly flow across the region but as the next shortwave in the broad upper level trough approaches, we will begin to see light southerly return flow ahead of another cold front. This will begin to increase rain chances across the area on Wednesday, but given the lack of any appreciable low-level moisture rain chances are likely to remain quite low. For Thursday and into the upcoming weekend, the cold front will likely begin to stall but dry mid-level air in the upper level trough should supress much of the shower and storm potential and help temperatures warm back up into the low 90s. && .AVIATION... (06Z TAFS) Issued at 122 AM EDT Sun Aug 31 2025 Beginning to get patchy MVFR cigs reported in southern Georgia and along the Florida coast. A moist northeasterly flow will aid in stratus development through the rest of the overnight into Sunday morning. There is some disagreement in near term guidance WRT coverage of stratus and leaned with the NBM guidance which is a little more pessimistic compared to LAMP/CONShort. Overall, not much change from the previous set of TAFs. IFR/MVFR cigs are expected to continue developing and affect the TAFs through around 14-16Z Sunday morning. Afterwards, a return to VFR or a mix of MVFR and VFR through 18Z then VFR in the afternoon hours. Seabreeze is expected to be located closer to the coast with rain decent rain chances south of I10 but confidence is not high enough to mention at TLH. && .MARINE... Issued at 122 AM EDT Sun Aug 31 2025 A frontal boundary over the nearshore waters will continue to settle further south into the Gulf into Tuesday. Northeasterly winds will be light through today but will likely increase Sunday night into Tuesday as the pressure gradient tightens. This could lead to periods of cautionary or near-advisory conditions, especially in waters west of Apalachicola. The frontal boundary moves east Wednesday with winds decreasing and becoming generally westerly later in the week. && .FIRE WEATHER... Issued at 122 AM EDT Sun Aug 31 2025 A drying trend takes hold over the next few days with afternoon and evening showers and thunder storms confined to the I-75 corridor of FL and the FL Big Bend. Moderate East-Northeast transport winds will be in place thru Tuesday with mixing heights away from the coast topping out around 5,000 feet. This promotes pockets of high afternoon dispersion across inland regions today and Monday. && .HYDROLOGY... Issued at 122 AM EDT Sun Aug 31 2025 As the frontal system slides south the higher rainfall totals will move south with it. Some rain is possible across the southeast Big Bend this afternoon but rainfall totals will be light and no hydrological concerns are anticipated. && .SPOTTER INFORMATION STATEMENT...
