| Area Forecast Discussion National Weather Service Tallahassee FL 122am EDT Tuesday September 8 2026 ...New SHORT TERM, LONG TERM, Marine IRE WEATHER,Hydrology .KEY MESSAGES... Issued at 122am EDT Tuesday September 8 2026 - A reduction in convective coverage is expected today and Wednesday, most notably north of the Florida state line. Coverage will once again increase starting Thursday as the air mass moistens. - Moderate heat-related impacts are expected each day for the next week, with heat index values reaching the 98-106 degree range each afternoon. There is a low chance of dangerous heat index values exceeding 107 degrees this weekend and early next week over our Florida counties. .SHORT TERM... (Today and Tonight) Issued at 122am EDT Tuesday September 8 2026 A turn to NE-E low-mid level flow over the last 24 hours has advected somewhat drier air across areas northwest of an Apalachicola-to-Valdosta line, where PW values (Precipitable Water values) have dropped into the 1.6 to 1.8 inch range. South of that line, PWs are still in the very moist 1.9 to 2.1 inch range. Within the drier air, it will be tough to eek out any convection today, partly due to the drier air and partly due to quick development of a strong 500 mb high across the Tennessee Valley, with corresponding height rises and warming aloft across our region. Further south in the moister air, scattered showers and storms are still expected, particularly late in the afternoon with the arrival of the Atlantic seabreeze in continued NE-E background flow. The background flow will pin the Gulf seabreeze very close to the coast, confining early-mid afternoon seabreeze convection to coastal communities. Long Term (Wednesday through Monday) Issued at 122am EDT Tuesday September 8 2026 Little change is expected during the day on Wednesday, compared with Tuesday. On Wednesday evening, the high pressure wedge nosing down the Carolina and Georgia Piedmont will start to quickly weaken, as the parent surface high abrupartly ejects from coastal NC out to Bermuda. Our low-mid level flow will turn easterly and southeasterly on Wednesday evening, then south and southwesterly on Thursday. Deeper moisture, which is currently only sidelined as far as the SE Big Bend and our Gulf waters, will easily return across the entire region from Wednesday night and Thursday. Meanwhile, Tuesday's strong 500 mb high development over the Tennessee Valley will dissipate and wash out just as quickly on Thursday, leading to geographically broad height falls, along with corresponding cooling aloft. This will take much of the lid off convective development, so a quick rebound in coverage of air mass convection is expected on Thursday, with that increased coverage continuing Friday. From Saturday through next Monday, a 500 mb high northeast of the Bahamas will expand in our direction and retrograde across the Carolinas and southern Appalachians by late Monday. Our upper heigheights will modestly rise. A surface high will get a foothold near the Delmarva region, turning our low-level flow from southerly to easterly on Monday. This pattern evolution will start to eat away at rain chances north of the FL state line, as rising heigheights and a turn to low-level easterly flow start to erode the northern edge of the maritime tropical air mass. Throughout the long term period, temperatures will run at or a little above early-mid September normals. Climatologically by Sept. 15, average temperatures have only cooled about 2-3 degrees from their summer season peak in mid July-mid August, so the continuation of warm/hot and humid weather is to be expected in the first 2 weeks of September. After September 15, normal temperatures start to cool off a degree about every 3-4 days through mid-November. For those waiting expectantly for cooler weather, you will be waiting longer, as the CPC 8-14 Day outlook valid Sep. 15-21 shows the likelihood of above normal temperatures. So we will be waiting a while longer for the first cool mornings of the fall season. Marine Issued at 122am EDT Tuesday September 8 2026 Moderate to fresh easterly breezes will continue over the waters through Wednesday morning. High pressure near the North Carolina Outer Banks will quickly exit east late Wednesday, allowing breezes to decrease and clock around southerly by Thursday. Light to gentle south and southwesterly breezes will continue through Saturday. Fire Weather Issued at 122am EDT Tuesday September 8 2026 Northeast to easterly transport winds of 10 to 15 mph will prevail through Wednesday morning. Over Southeast Alabama and Chattahoochee Valley districts, this will contribute to high dispersion values this afternoon. A somewhat drier air mass will be in place today and Wednesday , then a turn to southerly winds on Wednesday night and Thursday will bring a quick return of a moister air mass. After reduced coverage of thunderstorms today and Wednesday, the increased moisture on Thursday will push the daily thunderstorm coverage back up, continuing through the weekend. Patchy fog is possible around sunrise on Wednesday morning along and southeast of a line from Tallahassee to Valdosta. Hydrology Issued at 122am EDT Tuesday September 8 2026 No flooding is expected for the next 7 days. NOAA Tallahassee FL Office: Watches - Warnings - Advisories FL...None. GA...None. AL...None.
