951 FXUS62 KTAE 011350 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 950 AM EDT Mon Sep 1 2025 ...New UPDATE... .UPDATE... Issued at 948 AM EDT Mon Sep 1 2025 The forecast is on track. && .NEAR TERM... (Today and tonight) Issued at 233 AM EDT Mon Sep 1 2025 Little change is expected through tonight. In the grand scheme of our seasons around the tri-state region, fake fall is making a house call. If you look at normal temperatures, they do not typically even start the process of showing a sustained drop until after September 15. So think of this as either fake fall, or a reprieve from the summer weather that is still normal as we start September. A broad upper low centered over the U.S. Mid-Atlantic region has a fairly large cyclonic envelope, with a broad upper trough extending down through the Carolinas and Georgia. Meanwhile at the surface, a long fetch of NE wind is funneling down the Carolina and Georgia coastal plain and across our region, in the squeeze between high pressure near Lake Ontario and low pressure between NC and Bermuda. The NE flow will tap into the heart of a drier air mass over eastern Virginia and reinforce our drier and not-so-hot air mass on Monday. Shower chances on Monday will be confined to the SE Big Bend region, where deeper moisture and PW values of 1.5 to 1.8 inches will hang on. In contrast, anywhere north of I-10 will have drier Precipitable Water (PW) values of 1 to 1.5 inches, which is too dry to support deep, moist convection. With high temperatures on Monday running 2-5 degrees below normal and a moderate breeze all day long, it will feel uncommonly tolerable for this time of year. && .SHORT TERM AND LONG TERM... (Tuesday through Sunday) Issued at 233 AM EDT Mon Sep 1 2025 Broad upper trough across the eastern third of the US will remain in place as one upper low over the northeast US weakens and moves northeast while a stronger upper low dives from Canada towards the northern Great Lakes. Northeast low level flow will continue with high pressure over the Appalachians and the pesky stationary boundary to our south. As a cold front advances into the upper midwest Wednesday, aforementioned high pressure gets shunted eastward as well as the stationary boundary gaining momentum to push northeast and away from the region. This will break the low level northeast flow and send a pair of cold fronts toward the Gulf coast as the upper low spins across the Great Lakes region and back into southern Canada; the first arriving Friday but with dry air in place the arrival will be of little fanfare. The second front is at the end of this forecast period and appears to slow as it reaches the Gulf coast. PWATs will be fairly low (1.1-1.3 inches) through midweek with continued northeast low level flow and drier air from the Appalachians. The seabreeze will be pinned closer to the coast and low rain chances there and the southeast Big Bend. Heading into later this week, the northeast flow clocks to more of a westerly component with PWATs slowly increasing but more mid level dry air keeping rain chances low. It may not be till later next weekend that we experience an increase in rain chances with the second front possibly stalling and PWATs jumping back towards 2 inches. Temperature-wise through the week highs will slowly tick up into the low to mid 90s by Saturday while lows will mainly be in the middle 60s to lower 70s. && .LONG TERM... && .AVIATION... (12Z TAFS) Issued at 613 AM EDT Mon Sep 1 2025 VFR through the period. Northeast winds persist with some gustiness this afternoon at all sites up to 15-20 knots. && .MARINE... Issued at 233 AM EDT Mon Sep 1 2025 Small craft advisories remain in effect for the Gulf waters through this morning in waters east of Apalachicola and this afternoon in waters west of Apalachicola. Additional advisories may be needed tonight into Tuesday morning as well. As high pressure is anchored to our north and a stationary front to our south, northeast winds between these two features will persist into mid week. Nightly offshore surges are expected till then with ongoing advisories currently and possibly needed tonight as near 20 knot winds develop through Apalachee Bay transitioning to off the panhandle coast. Towards the end of this work week, winds slacken and clock to the west as the stationary boundary moves eastward. && .FIRE WEATHER... Issued at 233 AM EDT Mon Sep 1 2025 High pressure to the north will promote northeast winds over the next few days as well as drier air. Transport winds this afternoon will range between 15 to 20 mph while slightly lower speeds into mid week. Mixing heights will range between 4000 to 6000 feet with afternoon humidities falling into the low to mid 40 percent range. High dispersions today will be located through most of the Florida districts as well as the Alabama wiregrass region. Rain chances through mid week will be located mainly near the coast and southeast Florida Big Bend. && .HYDROLOGY... Issued at 233 AM EDT Mon Sep 1 2025 Comparably drier conditions will continue this week by late August and early September standards. Generally speaking, rainfall amounts through next weekend will average an inch or less. Therefore, no flash or riverine flooding is expected. && .SPOTTER INFORMATION STATEMENT...
