458 FXUS62 KTBW 282336 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 736 PM EDT Thu Aug 28 2025 ...New UPDATE, AVIATION... .FOR THE EVENING UPDATE... Issued at 726 PM EDT Thu Aug 28 2025 Weak high pressure remains over the Florida peninsula with light onshore boundary layer flow. Scattered showers and isolated thunderstorms over the eastern interior will gradually push east of the forecast area over the next couple of hours. Skies are currently mostly clear over the coastal counties of west central and southwest Florida...which will persist overnight. Considerable high cloudiness was located over the interior due to the convection in that region. Skies will become mostly clear across inland areas around or shortly after midnight. && .DISCUSSION... The current setup is a surface quasi-stationary boundary and upper level ridge axis in the very south of Florida; this general situation will remain throughout the weekend and early next week. With that in mind, a W/SW seabreeze flow will prompt scattered to numerous showers and thunderstorms. That is, morning convection will initiate on the Gulf coast and build up and concentrate inland and the east coast in the afternoon and evening hours. The main synoptic change to modify weekend weather conditions is a surface frontal boundary pushing through the SE U.S. This combination of a W/SW flow and frontal system will increase PW and bring up PoPs over the state. With increased rain chances, flooding risk is elevated, particularly Sunday and Monday. As for temperatures, highs will remain in the lower to mid 90s today and Friday, but increased cloud cover and rain chances will drop temperatures a few degrees during the weekend. && .AVIATION... (00Z TAFS) Issued at 726 PM EDT Thu Aug 28 2025 Predominately VFR conditions will continue tonight and Friday. A chance of afternoon showers will develop mainly vcnty LAL/PGD/FMY/RSW Thursday afternoon with LCL MVFR CIGs and IFR VSBYs. && .MARINE... A lingering frontal boundary will remain over or just north of the coastal zones through the weekend, allowing rain chances to gradually increase. Despite the proximity of the front, winds and seas are expected to remain light outside of daily thunderstorms. && .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 increasing showers and thunderstorms each day through the weekend. && .PRELIMINARY POINT TEMPS/POPS...
