516 FXUS62 KTBW 071828 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 228 PM EDT Sun Sep 7 2025 .DISCUSSION... Broad troughing remains aloft over the eastern half of the U.S. this afternoon while at the surface, a weak area of low pressure lingers over the eastern Gulf as a frontal boundary slowly moves over northern Florida. This setup has led to a moist southwest flow, with showers ongoing over the Gulf last night and early this morning now starting to move more inland and this trend will continue through the rest of the afternoon and evening. Locally heavy rainfall will continue to be a threat across the region and we do still have a marginal risk for excessive rainfall for the entire area. Increased rain chances will continue really through mid-week as the upper-level trough swings gradually swings eastward and the frontal boundary very slowly sinks southward across the peninsula. This will lead to a continued marginal risk for excessive rainfall at least through Wednesday before some relatively drier air moves into the southeast for the end of the week into the start of the weekend. This drier air will not make it very far southward but will lower rain chances for the northern part of our forecast area and thus lower the excessive rainfall threat for those same areas. It will be a different story south of wherever the dry air boundary lands, and those locations can expect continued high rain chances. && .AVIATION... (18Z TAFS) VFR conditions are expected outside of convection. Best storm chances for the rest of the afternoon and evening will be for KLAL and southwest Florida. Otherwise, a few leftover showers will linger, but then a quiet overnight period is expected before another round of showers and storms starting possibly early morning near the coast, but then more late morning/early afternoon activity will develop. && .MARINE... Weak low pressure will continue to spin over the easter Gulf for the next several days, bringing scattered to numerous showers and storms each day. Best chances will be mainly for the late night and morning hours, but will be possible at just about any time. No headlines are expected, though winds and seas will be higher in and near storms. && .FIRE WEATHER... No fire weather concerns for the next several days as relative humidity values will remain above critical levels. Warm and humid summertime conditions will continue, with scattered showers and thunderstorms each day. && .PRELIMINARY POINT TEMPS/POPS...
