.DISCUSSION... Issued at 320 AM EDT Sun Sep 7 2025
Currently at the surface, a weak area of low pressure is lingering over the eastern Gulf, with southwest low level flow continuing to pump deep moisture into the forecast area through at least mid week. This will result in numerous to widespread showers and thunderstorms, with a marginal risk of excessive rainfall leading to flooding each day as training storms allow a few spots to accumulate several inches of rain. Rainfall timing for the next few days will look similar to yesterday, with overnight showers and a few storms over the eastern Gulf pushing into the coast at times during the early morning hours, then the focus of convection will shift to over the Florida Peninsula during the afternoon. Otherwise, the rain and clouds will keep afternoon temperatures slightly below normal, with highs from the mid 80s to around 90.
By mid week, a mid level trough will slowly swing into the southeastern US then will lose steam during the second half of the week. At the surface, this will pull a weak frontal boundary south into the Florida Peninsula. This will bring a drier airmass into the Nature Coast Friday and Saturday, but without the benefit of stronger upper level support, numerous storm coverage is still expected south of Interstate 4.

.MARINE... Issued at 320 AM EDT Sun Sep 7 2025
A weak surface area of low pressure will continue to swirl over the eastern and central Gulf waters throughout the first half of the week, bringing scattered to numerous thunderstorms each day. Timing of rain chances will be mainly in the overnight and morning hours, then thunderstorms will develop over the Florida Peninsula in the afternoon, with a few storms possibly shifting back into the coastal waters during the evening. Late next week, easterly winds should favor a more typical afternoon thunderstorm pattern. No headlines are expected, although daily thunderstorms will produce locally hazardous winds.

.FIRE WEATHER... Issued at 320 AM EDT Sun Sep 7 2025
