Jacksonville, FL – Jacksonville faces a prolonged stretch of intense summer weather as daily thunderstorms and oppressive heat combine through Saturday, raising the risk of flash flooding and dangerous afternoon heat. Residents should expect heavy downpours and strong storms each afternoon and evening, with the highest chance for severe weather coming Thursday and Friday.
According to the National Weather Service, a persistent pattern of moisture will trigger repeated rounds of showers and thunderstorms, especially between 2 p.m. and 8 p.m. each day. Heat index values could climb past 105°F on Wednesday and Thursday, with high humidity and temperatures in the low 90s. Some storms may bring damaging winds, brief street flooding, and frequent lightning—especially across downtown Jacksonville, Orange Park, and along I-295.
Drivers should avoid flooded roadways and watch for rapidly changing conditions, particularly during the afternoon commute. Keep devices charged and consider alternate outdoor plans, as sudden downpours could delay events or close parks. Thursday appears to be the stormiest day, with near-constant thunderstorm coverage from midday into the evening. Friday and Saturday remain unsettled, though rain chances drop slightly by Sunday.
