KEY MESSAGES

- Chance of showers and thunderstorms expected today and tonight. - Mainly light to gentle east to southeast breezes will continue into the weekend, though occasional periods of moderate breezes will occur, especially south of the Island Chain.

DISCUSSION

Issued at 1030 PM EDT Fri Aug 28 2026

A surface ridge stretching across Central Florida is resulting in light to gentle easterly breezes along the Keys this evening. The latest sounding indicated ample CAPE, but with a tiny nose of low level inhibition. As a result, convective activity has been sparse. But what has been able to sprout had a good chance of becoming quite deep. Conditions are seasonable with temperatures in the mid 80s and dew points in the mid 70s.

Through the overnight, winds should increase a slight bit, but remain largely light. High instability with weak inhibition will remain through the night. Mesoscale models do indicate further convective development through the night and towards morning. The likely triggers will be the copious boundaries present across the area. Will maintain at least low chance PoPs. Expect overnight lows to be broadly in the lower to mid 80s with dew points holding in the mid 70s.

MARINE

Issued at 1030 PM EDT Fri Aug 28 2026

A surface ridge across Central Florida, along with the usual evening pickup, will result in light to gentle easterly breezes picking up to a gentle to moderate breeze. Only minor first period wind transitional wording has been adjusted in the evening marine update.

(00Z TAFS) Issued at 1030 PM EDT Fri Aug 28 2026
