| Area Forecast Discussion National Weather Service Tallahassee FL 945pm EDT Monday September 14 2026 ...New .KEY MESSAGES... Issued at 933pm EDT Monday September 14 2026 - Moderate to locally dangerous heat-related impacts are expected today and Tuesday, with heat index values generally reaching 100-108 degrees, especially over the Florida counties. - Small craft advisories are likely Tuesday night through Thursday as well as high risk for rip currents. Issued at 933pm EDT Monday September 14 2026 No major changes to tonight's forecast were required. A backdoor front is steadily dropping southward into the Wiregrass region this evening. This boundary is accompanied by a thin band of mid- level clouds and sub 70s dew points. As a result, we are looking at widespread low 70s for min temperatures by tomorrow morning and a preview of even cooler readings the following two nigheights as a drier airmass settles in further. .SHORT TERM... (This Evening through Wednesday Night) Issued at 228pm EDT Monday September 14 2026 Upper level ridging over the Southeast U.S. will continue to be the major influencer of our weather as the ridge strengthens for the next couple of days. The strong ridge will keep temperatures in the 90s, and bring in light northeast flow. This will reduce our atmospheric moisture, limiting PWATs (Precipitable Waters) to around 1.5" inland. The pro/con in this scenario is that: Con - it will still be hot. Pro - it will be less humid. The chances for rain will be minimal over land, as the ridge should keep shower/thunderstorm chances over the Gulf. At the surface, high pressure extending down the Apalachians will lead a "backdoor cold front" from our northeast that will increase our winds. Breezy conditions could begin as soon as Tuesday afternoon, and continue through Thursday until upper level the ridge retreats westward due to an inverted trough moving north- northwestward into the Gulf. Temperatures will be in the upper 90s this afternoon and mid-90s along the immediate coast. with heat indices ranging from 100-107 degrees. Expect lows tonight to be in the low-mid 70s. Temperatures Tuesday and Wednesday will be in the low to mid 90s, with max heat indices around 100-105 degrees. Overnight lows will be in the 70s with upper 60s Wednesday night into Thursday morning. For the rest of today, there may be some showers/thunderstorms along the Forgotten Coast with Probability of Precipitation ranging round 20-40% with better chances in the SE Big Bend. There's little to no chance for showers/thunderstorms for the remainder of the Short Term, except for localized areas along the coast, mainly in the SE Big Bend on Tuesday. Long Term (Thursday through next Sunday) Issued at 228pm EDT Monday September 14 2026 An inverted trough will move into the Gulf on Thursday, pushing the upper level ridge back westward. This will shift our winds back to southerly and increase our PWATs (Precipitable Waters) back to around 2 inches by the weekend. Temperatures will be not as hot in the upper 80s to low 90s however, dew points will increase back into the 70s. Afternoon Probability of Precipitation will return to 30-40%, with higher chances by the weekend. Marine Issued at 228pm EDT Monday September 14 2026 Beginning Tuesday, surface ridging taking place along the Appalachians Mountains that will extend south and into the Northern Gulf will create a pressure gradient increasing our marine winds. This will turn our current light northwesterly flow to a stronger easterly wind beginning, at earliest, Tuesday night through Thursday. This will result in winds reaching the threshold needed of 20 kts for a small craft advisory during this time. An upper level low will kick out this pattern, delivering a more moist airmass which will increase rain chances over the Gulf into the weekend. Fire Weather Issued at 228pm EDT Monday September 14 2026 High pressure overhead will continue our warm temperatures and generally dry conditions. Transport winds will become easterly on Tuesday with speeds of 10-15 mph and increase to 15-20 mph for Wednesday. As drier air will be filtering in, MinRH values will be in the mid-30s to mid-40s% for Tuesday and Wednesday. As somewhat breezy conditions build this week, dispersion values will increase to high for the Florida and Alabama Wiregrass regions, and the ANF near and along I-10. Healthy dispersions are expected to continue for Wednesday, with pockets of high dispersions throughout all the districts. Temperatures will be in the 90s with heat indices ranging from 100-107 through Tuesday. When the drier air filters in, heat indices will be lower, as well as windier conditions (previously mentioned). Hydrology Issued at 228pm EDT Monday September 14 2026 No flooding concerns over the next several days. NOAA Tallahassee FL Office: Watches - Warnings - Advisories FL...None. GA...None. AL...None.
