Issued at 200am EST Sunday Nov 1 2026

Early morning water vapor and IR satellite imagery is showing a shortwave trough over the northeastern Gulf swinging into the Florida Peninsula today, bringing increased atmospheric moisture and a period of disturbed weather. As strong surface high pressure holds north of the state, breezy easterly flow will continue across the area today, with showers and light rain continuing to stream west into the forecast area through the morning, then scattered to numerous showers and storms will shift onshore from the Gulf this afternoon and evening as the shortwave continues to build in. Cooler mid level temperatures in the vicinity of the shortwave will result in steeper lapse rates, which should allow for increased chances of thunder today, but with unidirectional wind shear, the main storm threat other than lightning will be for some areas of heavy rainfall. This shortwave is forecast to cut off from the main flow and linger over Florida Monday and into early Tuesday, with increased rain chances continuing.

By midweek, an upper level trough will be crossing the Mississippi River Valley into the eastern US, with a developing surface low forecast to lift northeast through the Great Lakes through late in the week. This system will develop a weak cold front that will sweep through the southeastern US Wednesday before making a dry frontal passage through the Florida Peninsula Thursday night and Friday. While temperatures will briefly warm up ahead of this front Tuesday through Thursday, cooler air will fill in behind the front, with overnight lows forecast to drop into the upper 50s to mid 60s by Saturday morning.

High pressure holding north of Florida is keeping the persistent breezy easterly flow in place through early next week. Winds will continue to run at Small Craft Exercise Caution levels through at least early Tuesday, approaching Small Craft Advisory levels at times. In addition, an upper level disturbance will result in increased coverage of showers and thunderstorms today and Monday, producing locally higher winds and hazardous boating conditions. Wind speeds will subside Tuesday through the rest of the week as the pressure gradient begins to relax.

Fire Weather
Issued at 200am EST Sunday Nov 1 2026

Deep moisture will hold across the area today and Monday, bringing increased coverage of showers and thunderstorms. Breezy east and northeast winds will continue each day.
