280 FXUS62 KTBW 070029 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 829 PM EDT Sun Jul 6 2025 ...New UPDATE, AVIATION... .UPDATE... Issued at 828 PM EDT Sun Jul 6 2025 Isolated spotty showers continue to develop across the Tampa Bay area, aided by a couple lingering boundaries and local axis of increased instability. Some CAMs are hinting that this may continue through the evening and into the night. However, increased stability over land should keep this confined to only a very small portion of the coastline, if this does continue to occur. Otherwise, the forecast remains on track this evening as the WSW flow continues. && .DISCUSSION... The upper low has moved further west into the Gulf today while TD Chantal and remnants move through the Carolinas with the local area between these features. The latest surface analysis continues to indicate a weak boundary remains stretched across the I-4 corridor with generally light-moderate SW flow over the Peninsula. Most of the area is fairly rain free early this afternoon since earlier outflows pushed well inland much sooner than typical Gulf seabreeze. But, the area remains in a very moist airmass and unstable environment during additional diurnal heating, so expect additional WNW moving showers and thunderstorms through the late afternoon and evening hours. Then with typical regime 5 expected E Gulf convection to redevelop overnight as the warm and humid conditions continue. SW flow through Monday before transitioning to more typical summertime pattern as the Bermuda high pressure ridge axis builds back over and meanders over the FL Peninsula mid-late week and into next weekend with afternoon and evening thunderstorm patterns and warm near normal temps. && .AVIATION... (00Z TAFS) Issued at 828 PM EDT Sun Jul 6 2025 Some coastal showers will continue overnight in the vicinity of Tampa Bay Area terminals as a WSW flow continues while SWFL remains quiet until early tomorrow morning and inland areas after sunrise. With this flow continuing, the window for thunderstorms will be earlier and shorter, before thunderstorms transition inland. This will continue to linger into Tuesday before conditions begin to change Wednesday and late week back to a more typical afternoon and evening window for thunderstorms. && .MARINE... Southwesterly flow will continue through Monday then weak high pressure will build over the Central Gulf with generally light winds and slight seas through the week. Expect daily summertime showers and storms to produce brief gusty winds that will increase choppy seas in and near convection. && .FIRE WEATHER... Warm and humid summertime conditions will continue through the week with seabreezes along with scattered to numerous showers and thunderstorms each day. && .PRELIMINARY POINT TEMPS/POPS...
