1220am EDT Fri August 28 2026

Issued at 1202am EDT Fri August 28 2026 High pressure surface and aloft will persist over west central and southwest Florida for the next several days. Light southerly boundary layer flow will shift to the southwest this morning with scattered to numerous showers and thunderstorms developing over the coastal counties. The showers/storms will push inland during the afternoon hours and increase in areal coverage. A few storms may be strong with wind gusts of 40 to 50 MPH.

Over the weekend, light east to southeast boundary layer flow will develop which will hold the west coast sea breeze boundary over the coastal counties. The east coast sea breeze boundary will push across the peninsula through the day with scattered showers and storms. Areal coverage of storms will increase over the coastal counties late in the day as the east coast sea breeze boundary collides with the west coast sea breeze boundary. A few storms may be strong with damaging wind gusts.

Similar pattern will hold through the middle of next week. Some drier air aloft will advect over the northern forecast area which will decrease areal coverage of storms across the nature coast, with highest probability of precipitation over southwest Florida in region of best available deep layer moisture. The drier air aloft may increase the risk for a few strong storms each day.

Marine
Issued at 1202am EDT Fri August 28 2026 High pressure will hold over the waters through the forecast period with generally light winds and seas. The main hazard will be scattered to numerous showers and thunderstorms, mainly during the evening and overnight hours, which may produce locally gusty winds and rough seas.

Fire Weather
Issued at 1202am EDT Fri August 28 2026 No fire weather hazards are expected as sufficient moisture will keep minimum afternoon relative humidity values well above critical levels for the next several days.
