488 FXUS62 KTBW 230015 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 815 PM EDT Fri Aug 22 2025 ...New UPDATE, AVIATION... .UPDATE... Issued at 815 PM EDT Fri Aug 22 2025 The west to southwest flow with abundant moisture, precipitable over 2 inches, will continue across the area through the weekend. Therefore, the scattered to numerous showers and thunderstorms will continue and with so much moisture in place they could occur at almost anytime. There will also be the potential for some locally heavy rainfall in spots, especially from areas around Tampa Bay north where repeat convection moving off the gulf is most likely. Overall the forecast looks on track with no changes needed at this time. && .AVIATION... (00Z TAFS) Issued at 815 PM EDT Fri Aug 22 2025 Abundant moisture with an unstable airmass will lead to scattered to numerous showers and thunderstorms. The favored time for this convection at the TAF sites is late tonight into early Saturday afternoon, but could see a shower or thunderstorm at almost anytime. MVFR/local IFR conditions will be possible in the convection, otherwise VFR conditions should prevail. Light southwest tonight will become southwest to west at around 10 knots by Saturday afternoon, except gusty and erratic near showers and thunderstorms && .DISCUSSION... Issued at 158 PM EDT Fri Aug 22 2025 W/SW flow in place across the area will continue through the weekend as a boundary lingers across north Florida and the SE US and the ridge axis remains across the FL Straits. This will keep morning and early afternoon timing for convection. A slight risk for excessive rainfall will be in place for tomorrow for the northern Nature Coast, as the area has received plenty of rainfall today and grounds are saturated. The boundary then shifts to across the southern half of Florida for the first half of next week, keeping deep moisture across the area and the earlier storm timing. Winds transition back to the E/SE for the rest of the week, shifting the main convection timing to the afternoon and evening with the seabreeze. Temperatures will generally be in the upper 80s to lower 90s for highs, with mid 70s to lower 80s for lows. && .MARINE... Issued at 158 PM EDT Fri Aug 22 2025 W/SW flow will continue across the waters, keeping the best chances for convection over the waters mainly in the overnight and morning hours. Winds transition back to the E/SE mid-week, shifting storm timing more to the evening and overnight hours as storms push offshore. Winds remain below any headlines through the period. && .FIRE WEATHER... Issued at 158 PM EDT Fri Aug 22 2025 Scattered to numerous showers and storms are expected each day through the middle of next week beginning along the coast and shifting inland through the day. && .PRELIMINARY POINT TEMPS/POPS...
