- A typical summertime pattern will continue through the holiday weekend. Rain chances will remain at seasonable levels (20-30%), with the usual hot and muggy conditions.

DISCUSSION

Issued at 430 AM EDT Sat Jul 4 2026

Sloppy surface through lower level ridging across Florida and the southeast is responsible for light mostly southeasterly breezes across the Keys this morning. Conditions are seasonable with temperatures in the lower 80s with dew points in the upper 70s. Last evenings sounding indicated ample instability and deep layered moisture. As a result, a few clusters of showers with an embedded thunderstorm or two have been present across the forecast area.

The western flank of Atlantic ridging will build across the Florida Peninsula this weekend. This will result in light to gentle mostly southeasterly breezes across the Keys this weekend. This seasonable regime will persist well into next week, and result in near normal temperatures with highs near 90 and lows in the lower 80s. Dew points will linger in the mid to upper 70s. Nebulous flow aloft and dominant ridging through the lower troposphere should result in near normal slight to low chances for showers and thunderstorms.

MARINE

Issued at 430 AM EDT Sat Jul 4 2026

Weak ridging will meander across the Florida Peninsula through the weekended and into next week. This will keep breezes light to gentle and broadly southeasterly. No major changes made in the morning marine forecast.

(06Z TAFS) Issued at 430 AM EDT Sat Jul 4 2026
