DISCUSSION

Issued at 1030 PM EDT Sat Aug 29 2026

A broad Atlantic ridge reaches westward through the Southeastern United States this evening and is maintaining light to gentle broadly easterly breezes across the Keys this evening. This evenings sounding indicated precipitable water just north of the 90th percentile at 2.2 inches. In addition, inhibition was very weak with good CAPE. These variables along with a lack of mid and upper level ridging was supportive of scattered showers with embedded thunderstorms. Some of the thunderstorms rapidly developed into strong cells. In recent hours, activity has waned substantially, now with just a few showers dotting our southern waters. Seasonable conditions are in place with temperatures in the mid 80s and dew points in the mid to upper 70s.

No significant change to the weather setup is expected overnight. An overall wetter than normal pattern will continue due to the high deep layered moisture, ample CAPE, minimal inhibition, and the usual enhanced nocturnal confluence. Expect the quiet weather in the very near term to give way to increasing shower and thunderstorm coverage. Expect overnight lows in the lower to mid 80s with dew points remaining in the mid to upper 70s.
