584 FXUS62 KTBW 020722 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 322 AM EDT Mon Jun 2 2025 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .DISCUSSION... Issued at 322 AM EDT Mon Jun 2 2025 In the upper levels, a deep trough axis is stretched out from eastern Canada through the Mid-Atlantic states, while a developing short wave over the Mississippi Delta is rounding the base of the trough and will reach the eastern Gulf by this evening. This shortwave will then cutoff from the main flow and linger through at least Wednesday night in the vicinity of Florida before lifting out to the north during the second half of the week. At the surface, weak and somewhat variable westerly flow is holding in place today. With deep moisture remaining across southwest Florida from the remnants of a stalled front, scattered showers and storms are developing over the eastern Gulf early this morning and shifting east into the Florida Peninsula, mainly south of the Tampa Bay. By mid afternoon, these storms over the waters will be fading out, with the focus of convection shifting into the interior through the late afternoon, but high resolution models are hinting that storms could build back west into the coast during the early evening hours. By Tuesday, broad surface high pressure will setup north of Florida, favoring southeast to east flow that will hold through at least Thursday. As moisture increases from the southeast, the previously mentioned shortwave will drop temperatures aloft, increasing instability, while developing a weak surface wave. As a result, scattered to widespread showers and storms are expected Tuesday through Wednesday night before the shortwave and surface wave lift out. Thursday through the weekend, the surface high will ridge across the central Florida Peninsula, resulting in light southeast to southerly flow. This pattern will bring scattered to numerous showers and storms, mainly in the afternoon and early evening. && .AVIATION... (06Z TAFS) Issued at 322 AM EDT Mon Jun 2 2025 Showers are shifting onshore from the Gulf this morning across southwest Florida and will bring periods of reduced flight categories to area terminals south of the Tampa Bay through at least the morning. For KRSW, KFMY, and KPGD, these storm chances will continue through the entire afternoon, with potential for several periods of disruptions. Farther north around KTPA, KPIE, and KLAL, the most likely time for storm impacts will be between 19-02z as storms build back to the west. && .MARINE... Issued at 322 AM EDT Mon Jun 2 2025 High pressure will gradually build in north of Florida today and Tuesday, with light and variable flow today becoming southeasterly and easterly Tuesday through Thursday, then more southerly by Friday. Showers and storms developing over the eastern Gulf early this morning will shift onshore through the rest of the morning and early afternoon, mainly from around the Tampa Bay south. The rest of the week, the highest rain chances will be in the afternoon and early evening as storms push west into the coastal waters from the Florida Peninsula. Wind speeds and sea heights will generally remain less than headline criteria, but daily thunderstorms will produce locally hazardous boating conditions. && .FIRE WEATHER... Issued at 322 AM EDT Mon Jun 2 2025 Drier air over the Nature Coast will drop relative humidity percentages into the upper 30s this afternoon, but widespread critically low humidity is not expected. && .PRELIMINARY POINT TEMPS/POPS...
