Jacksonville drivers may need extra caution Friday afternoon as thunderstorms build along I-95, bringing sudden downpours and gusty winds. Hot September air fuels storm chances through the weekend, raising concerns for outdoor events, travel, and Friday night football games.
According to the National Weather Service in Jacksonville, Thursday will stay sunny and dry with a high near 88. Winds increase Friday, shifting northeast with gusts up to 18 mph as storm chances rise to 20 percent in the afternoon. Conditions stay unsettled into the weekend, with higher chances of evening showers and isolated storms each day.
Saturday and Sunday both bring 30 percent rain chances after 2 p.m., paired with highs in the lower 90s. That mix of heat and humidity will push heat index values well above 95, adding to health risks for outdoor workers, athletes, and vulnerable residents. Lightning delays are possible for football games and weekend festivals.
Travelers should watch for ponding on roadways, especially I-10 and I-95, during downpours. Storms may cause short-lived traffic slowdowns but are not expected to bring widespread flooding. Residents should hydrate often, limit strenuous outdoor activity, and keep weather alerts active for changing conditions.
The pattern turns wetter early next week, with storm chances increasing to 60–70 percent by Monday and Tuesday.
Warnings could be issued if thunderstorm activity intensifies. Stay alert for updated advisories.
