| Area Forecast Discussion National Weather Service Tallahassee FL 850pm EDT Monday September 29 2025 ...New Issued at 844pm EDT Monday September 29 2025 No updates made to the forecast this evening. Additional low-level clouds like last night will again roll into the area from the northeast overnight leading to overcast skies by morning. Near Term (Through Tuesday) Issued at 143pm EDT Monday September 29 2025 The moist east flow around the north side of Tropical Storm Imelda continues to bring in cloud cover and widely scattered light showers this afternoon. The showers will largely fade this evening, but another stratus deck will move into the area again tonight. This will keep lows rather warm in the upper 60s to lower 70s. While there won't be quite as much moisture tomorrow to work with, mostly cloudy skies with isolated light showers will still be possible. The best chance (20-30% will be near the I-75 corridor into the Suwannee Valley. Nudged highs down a degree or two with highs mostly in the mid 80s for Tuesday given the cloud cover and persistent northeasterly flow. .SHORT TERM & Long Term (Tuesday night through Sunday) Issued at 143pm EDT Monday September 29 2025 As Imelda turns out to sea, a backdoor cold front moves south through our area Wednesday. Wednesday will see generally less stratus as moisture decreases, so highs will be in the upper half of the 80s. Thursday, behind the front, cooler air tries to make its way down from the Appalachians. It doesn't quite look like a stratus/cold air wedge setup yet on Thursday, so highs will still be in the low to mid 80s. Beyond Thursday, the cold front stalls to the south of our marine area and high pressure really establishes itself over the Appalachians and Northeast US. Meanwhile, a mid-level shortwave over the western Gulf will impart southwesterly flow aloft above the surface northeast flow. This is usually a more classic stratus/cold air damming setup for us, and there is the potential the highs could bust on the high side heading into the weekend. Right now, forecast highs are generally in the low to mid 80s, but global models at this juncture usually don't handle ambient conditions in these scenarios well. For now, have started nudging highs downward from guidance, but we could very well see highs struggle to get out of the 70s, especially over southern Georgia, where there is about a 50/50 shot at this. The tight pressure gradient between our high to the north and front to our south will result in breezy conditions heading into the weekend. Gusts of 20-30 mph will be common each afternoon from Thursday through the weekend. A weak inverted trough or area of low pressure may develop along the front over the weekend, which will send more moisture back into our area and increase rain chances. Right now, it appears this will be more stratiform rain rather than thunderstorms with the front to our south. While heavy rain is not expected, we'll keep an eye on things just in case the front wobbles back to the north near the coast. Long Term Marine Issued at 143pm EDT Monday September 29 2025 Impactful marine conditions are expected later this week. There is about a 60-90% chance of Small Craft Advisory conditions beginning as early as Wednesday night and continuing through the weekend. There is also about a 10-20% chance of gale-force gusts each night from Thursday night to Saturday night in the nocturnal surges. From CWF Synopsis: Moderate to fresh north to northeast breezes will continue for the next couple days with nocturnal surges resulting in cautionary conditions. A cold front moves through the marine area Wednesday into Thursday, which will increase winds to near advisory level. The front stalls to our south, and the pressure gradient tightens between it and the large sprawling high building to the north. This will result in a prolonged period of small craft advisory conditions with gusts to near 30 knots. Seas will also build from 2 to 4 feet early in the week to 5 to 8 feet late in the week into the weekend. Fire Weather Issued at 143pm EDT Monday September 29 2025 Northeasterly transport winds around 15-20 mph will continue over the next several days. Mixing heigheights will gradually increase day by day, leading to increasing dispersions by Wednesday and Thursday with high dispersions possible Thursday afternoon. A cold front will move through the area Wednesday, which will bring a shot of drier air to the region with min RH values dropping into the mid to upper 30s. Winds will also increase Thursday and beyond, which may increase fire weather concerns late in the week into the weekend. Hydrology Issued at 143pm EDT Monday September 29 2025 Outside of light showers over the next day or two, no significant rainfall is anticipated until this weekend. A front stalls to our south late in the week into the weekend, which may increase rain chances, but most likely totals remain under an inch for the most part. As of now, flooding is not expected.
