635 FXUS62 KTAE 080101 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 901 PM EDT Mon Sep 7 2026 ...New UPDATE... .KEY MESSAGES... Issued at 856 PM EDT Mon Sep 7 2026 - Showers and thunderstorms will remain in the forecast each day for the next 7 days. The greatest chance will come during the afternoon through early evening hours. - Heat indices will run in the upper 90s to lower 100s Tuesday and Wednesday with increasing heat indices later this week. && .UPDATE... Issued at 856 PM EDT Mon Sep 7 2026 The east coast sea breeze has made it through the eastern half of our area with only a few showers left. Thus, little coverage of showers or storms is expected on land for the rest of the evening with most of the activity being confined offshore. Thus, rain chances and temperatures were adjusted for current trends. This only resulted in a slight reduction in rain chances but no other significant rain chances. && .SHORT TERM... (This Evening through Tuesday) Issued at 319 PM EDT Mon Sep 7 2026 Weak frontal boundary is analyzed this morning along and just south of I10 from the east coast of Florida westward into the Florida panhandle then northwest towards central Alabama and Mississippi. North of the area, high pressure is located throughout the Great Lakes with wedging strengthening through the southern Appalachians reinforcing the turning of the low level winds more northeasterly to easterly with drier air working in from the north as well. Satellite derived PWATs are 1.6-1.8" north of the Florida state line to near 2 inches closer to the coast. Aloft, ridging is located across the central US and troughing is located down the eastern seaboard southwest to the Gulf. Drier air will continue moving south as the wedging extends further southwest towards southern Alabama and the surface boundary pushes southward across the Florida peninsula. PWATs range from 1.4" in the wiregrass to 1.9" along the coast. The central US mid level ridging elongates and extends towards the southeast US coast adding in increasing mid level subsidence through the area. The increasing drier air and subsidence will act to suppress greater coverage of convection Tuesday and lowered rain chances especially west and north of the Florida Big Bend. As low level flow turns northeast and east, the east coast seabreeze will generally be the main driver for the better coverage of convection whereas the Gulf coast seabreeze will generally be pinned closer to the coast. High temperatures will generally reach the lower 90s. Lowered dewpoints in the afternoon by 1-2 degrees which yields heat index values in the upper 90s to mid 100s; this should preclude heat related headlines Tuesday afternoon. && .LONG TERM... (Tuesday night through next Sunday) Issued at 319 PM EDT Mon Sep 7 2026 The same general setup from Tuesday will apply to Wednesday. Easterly flow remains with high pressure to the north and subsidence aloft as mid level ridging reaches the southeast US coast. Lowered rain chances Wednesday by 10-20%, especially north of the Florida State line where lower PWATs will reside with the highest of rain chances along the coast and then the Big Bend later in the day as the east coast seabreeze arrives. Ridging shifts off the east coast Thursday as a trough enters the central US and Midwest. At the same time, surface ridging weakens and the front to the south dissipates setting up a return to deep layer southwesterly flow. This will bring moist air back from the Gulf with PWATs jumping back up to 2-2.2" into the weekend. Rain chances will remain elevated as subsidence moves east with the Gulf coast seabreeze taking shape each day with southwest surface and low level winds. Highs will generally reach the low 90s each day with heat index values in the low to mid 100s. Though further out, there may be a need for heat advisories beginning Thursday for portions of the area as dewpoints creep back up on southwest winds. && .AVIATION... (18Z TAFS) Issued at 113 PM EDT Mon Sep 7 2026 A few showers and storms may develop later this afternoon or evening across far south GA and into FL. Confidence is on the lower side at the moment. Otherwise, VFR conditions are expected. && .MARINE... Issued at 319 PM EDT Mon Sep 7 2026 Winds turn northeast to east tonight and for the next couple of days as high pressure builds out through the Carolinas with speeds generally moderate to fresh. Easterly winds will die off quickly on Wednesday night and then becoming gentle southwesterlies on Thursday. Chances for showers and thunderstorms will continue into the weekend. && .FIRE WEATHER... Issued at 319 PM EDT Mon Sep 7 2026 Surface winds will gradually shift from northeast this afternoon to east Tuesday and Wednesday as high pressure shifts into the Carolinas and some drier air pushes towards the Gulf coast. Higher rain chances will also shift towards the Florida counties and Big Bend during this time. High pressure shifts off the east coast beginning THursday with winds clocking around to southwesterly. This will draw up increasing moisture from the Gulf as well as increasing rain chances and coverage of storms area wide into the weekend. Highs will generally reach the lower 90s each day. Heat indices the next couple of days will be in the upper 90s to lower 100s; somewhat higher heat indices will return Thursday with increasing moisture possibly necessitating heat advisory headlines in portions of the area as heat indices may approach 108-110F. && .HYDROLOGY... Issued at 319 PM EDT Mon Sep 7 2026 No flooding is expected for the next 7 days. Short-lived nuisance runoff issues are possible beneath the heaviest thunderstorms. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
