Jacksonville is starting Sunday under mostly cloudy skies, with temperatures in the upper 70s and a steamy afternoon ahead. Highs should reach about 87 degrees before showers and thunderstorms become more likely during the afternoon. The rain may offer some relief, but it will not exactly cancel summer.
The National Weather Service Jacksonville office forecasts scattered to numerous showers and thunderstorms today, with low-level east-northeasterly flow. Storm coverage should increase during the afternoon as showers move inland from the Atlantic, and heat index values could approach 100 degrees before clouds and rain build in, according to the National Weather Service.
Scattered to numerous showers and thunderstorms are expected, and isolated stronger storms are possible, especially west of the Interstate 95 corridor. The strongest cells could bring frequent lightning, brief heavy rain, gusty winds of 35 to 45 mph and possibly small hail.
Storm Chances Stay High Through Wednesday
Sunday night will have lows of 70 to 75 degrees, with continued overnight coastal showers or thunderstorms. Monday brings another hot day, with temperatures in the upper 80s to lower 90s and showers and thunderstorms.
Rain chances rise to 60% Tuesday, when another high near 89 is expected, followed by continued showers and thunderstorms Wednesday. Slow-moving storms could produce locally heavy downpours, while breezy northeast winds become more noticeable along the coast and the Interstate 95 corridor.
Cooler, Breezier Pattern Arrives Late Week
Cooler temperatures arrive Thursday through Saturday. Northeast winds are expected to strengthen Thursday and Friday, bringing rougher marine conditions.
A moderate rip-current risk is expected at Jacksonville-area beaches through midweek. Beachgoers should stay out of the water when thunderstorms are nearby and follow posted surf advisories.
