197 FXUS62 KTBW 161855 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 255 PM EDT Sat Aug 16 2025 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .DISCUSSION... Issued at 255 PM EDT Sat Aug 16 2025 Deep moisture, precipitable water around 2.0 inches, will remain across much of the area through Monday, with the slightly less across southwest Florida. A light easterly flow will continue which will allow for a decent sea breeze each afternoon and this combined with daytime heating will lead to scattered to numerous afternoon and evening showers and thunderstorms with activity drifting west out into the Gulf each night. For Tuesday and Wednesday, some drier air will try to move in from the northeast, but this depends a lot on the track of Erin. If it tracks closer to the southeast U.S. then we`ll see more drier air wrapping southward around it into the Florida peninsula, but if it stays further out we`ll see less. For now it looks like we`ll have enough moisture for at least scattered afternoon and evening convection each of these days with a more northeast to north flow. For the Thursday into next weekend the flow will shift to a more westerly direction with plenty of moisture remaining across the region for scattered showers and thunderstorms. However, this flow (Regime 4) will favor the interior and eastern half of the Florida peninsula for scattered to numerous showers and thunderstorms during the afternoon and evening hours, with isolated to scattered convection over the eastern Gulf waters moving onshore during the late night and morning hours. && .AVIATION... (18Z TAFS) Issued at 255 PM EDT Sat Aug 16 2025 Scattered showers and thunderstorms are expected into this evening which could cause some MVFR/local IFR conditions along with gusty erratic winds. Otherwise, VFR conditions are expected to prevail through the TAF forecast period. Light winds will become west northwest with the sea breeze at the TAF sites near the coast this afternoon, then become light again later this evening into Sunday morning. && .MARINE... Issued at 255 PM EDT Sat Aug 16 2025 Relatively light east winds will turn onshore with the sea breeze each day through Monday, remaining below headlines. Scattered showers and thunderstorms will be possible over the Gulf during the nighttime and early morning hours, then most activity will shift over land through the rest of each day. By the middle of next week a more north to northeast flow will setup, but still be rather light with winds 10 knots or less. && .FIRE WEATHER... Issued at 255 PM EDT Sat Aug 16 2025 No fire weather concerns for the next several days as relative humidity values will remain above critical levels and winds less than 10 mph, except gusty and erratic in the vicinity of showers and thunderstorms. Warm and humid summertime conditions will continue, with scattered showers and thunderstorms each day. && .PRELIMINARY POINT TEMPS/POPS...
