Expect scattered showers and thunderstorms throughout Friday, with the heaviest rainfall likely occurring from the early to late morning hours. A weak trough moving along the coast, combined with light wind shear, increasing Gulf moisture, and an unstable atmosphere, will create a favorable environment for heavier rainfall, particularly near the coast.

Rain could be heavy at times, with some areas near the coast picking up as much as three-quarters of an inch. A few stronger storms could also produce wind gusts of 40–50 mph.

High temperatures will be in the lower 90s, with low temperatures in the lower 80s. Heat index values could vary between 105 and 108 degrees during the day.

On Friday evening and overnight, expect some patchy fog along and near the coast due to the increased moisture in the area.

Scattered Light Weekend Showers and Thunderstorms

On Saturday and Sunday, expect scattered light showers and thunderstorms all throughout each day with patchy fog due to the high moisture content on both nights, especially near the coast.

Temperatures will be in the lower 90s as the highs with the lows lingering in the lower 80s. Heat index values will range between 105 and 108 on Saturday.

Partly cloudy skies will remain Saturday and Sunday. Winds will be from the south at 10-15 mph for both days.
