987 FXUS62 KTBW 111315 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 915 AM EDT Sat Oct 11 2025 ...New UPDATE... .UPDATE... Issued at 914 AM EDT Sat Oct 11 2025 A stubborn stratus deck covers most of the area this morning as abundant low level moisture remains in place. The low clouds will generally be rather slow to erode and lift as the low level moisture only slowly scours out so expecting mostly cloudy skies to linger for much of the day. This combined with troughing aloft should keep highs from reaching climatological normal values, which will yield highs around 3-5 degrees below normal for most areas today. Other than some minor adjustments to sky cover this morning based on recent satellite trends, the forecast remains on track at this time. && .KEY MESSAGES... Issued at 144 PM EDT Fri Oct 10 2025 - Hazardous marine conditions will continue through the weekend. Winds of 20 to 25 knots are forecast in coastal waters north of Englewood, creating seas of 5 to 8 feet offshore and 3 to 5 feet nearshore. Tampa Bay will see wave heights of 2 to 4 feet south of the Interbay Peninsula to Egmont Key. - There is only a 10% to 20% chance of showers near the coast today, with a 20% to 30% chance of showers across the interior. The highest potential will be in the late afternoon. It will be mostly cloudy and breezy today. - Nice, drier weather is forecast through midweek before gradual warming takes place late in the week. The next significant cold front arrives late next weekend. && .DISCUSSION... Issued at 222 AM EDT Sat Oct 11 2025 With an upper-level low over North Florida, a Nor`easter is taking shape off the Florida east coast. This setup has dragged slightly more mild and a significantly drier airmass over the western half of the peninsula in the mid and upper-levels. The gradient also remains strong, favoring a continued gusty flow across coastal waters. However, the more fall-like weather conditions have not yet translated to the surface areawide. While dewpoints across the Nature Coast and Big Bend region have dropped in the low-to-mid 60s, dewpoints remain in the 70s across Central and Southwest Florida. It`ll really take another day for this to fully sink in - and that is because low-level NE flow is still feeding moisture into the area as the low organizes off the East Coast. Over the next 24 hours or so, the low will pull away as the trough axis positively tilts over the Eastern Seaboard, forcing the storm system up the east coast in the Carolinas into the vicinity of the Carolinas. The system will then start to shear out as a strong ridge builds in from the west and squeezes the trough between itself and the subtropical ridge to the east. As this occurs, ridging will build back in across the Florida peninsula, allowing winds to subside somewhat - and gradually, the winds will veer to a more ENE direction and eventually easterly direction. This will allow temperatures to warm during the second-half of the week, with dewpoints also creeping back up as well. Overall, though, the forecast looks fairly benign during the work week. Rain chances are low, skies should be mostly sunny, and the mornings and evenings in particular will feel pretty good. It`ll still be warmer in the afternoons (especially later in the week) - but still not quite as warm as it has been. Overall, it should be a fairly nice stretch of weather to carry us into the weekend when change will be on the horizon once more as another front approaches the region. && .AVIATION... (12Z TAFS) Issued at 732 AM EDT Sat Oct 11 2025 A combination of MVFR/IFR CIGs are in place this morning across most of the region, though coverage of low CIGs is not quite as extensive for SWFL terminals. The low CIGs will be slow to scatter out this morning and will likely linger through around 18Z before VFR conditions then return area-wide through the remainder of the day period. Surface winds will be out of the N-NE today and breezy at times with gusts around 15-20 kts winds should then fall to 5-10 kts overnight. && .MARINE... Issued at 222 AM EDT Sat Oct 11 2025 Hazardous marine conditions continue across coastal waters as gusty winds of 20 to 25 knots build seas up to 8 feet offshore, making conditions hazardous for small craft. Winds are forecast to begin subsiding overnight, and seas will gradually subside in response. However, this will take several hours, and slightly lighter but still gusty winds on Sunday still favor conditions requiring small craft to exercise caution on Sunday. As winds and seas become lighter during the workweek, marine conditions will improve. && .FIRE WEATHER... Issued at 222 AM EDT Sat Oct 11 2025 Gusty northeast winds will keep some higher dispersions in play as a drier airmass moves into the region. However, low-level moisture will remain sufficient to keep min RH values in the 50% to 70% range. Thus, red flag concerns are low at this time through the week. && .PRELIMINARY POINT TEMPS/POPS...
