.UPDATE... Issued at 924 AM EDT Fri Sep 26 2025
Radar is showing a few very light showers over the northeastern gulf waters, but otherwise it is a very pleasant morning with mostly sunny skies across west central and southwest Florida. Southwest winds ahead of a frontal boundary to the northwest will persist through the day. Latest model guidance shows showers and storms developing along the sea breeze this afternoon as it pushes inland and ahead of this frontal boundary. The highest rain chances appear to be from Manatee County northward and over the interior. Near seasonal temperatures expected topping out in the upper 80s to low 90s. Forecast looks good with no changes needed at this time.
