Jacksonville, Fla. – Soaring summer heat and a sudden surge of afternoon thunderstorms could disrupt commutes and outdoor plans across Jacksonville this Thursday, with risks extending well into the weekend. Area drivers, especially on I-295, should prepare for slick conditions and rapid changes in visibility as storms intensify after midday.
According to the National Weather Service, a slight chance of showers will give way to widespread thunderstorms across Jacksonville and Duval County after 11 a.m. Thursday. Temperatures are expected to reach 93°F, with humidity making it feel even hotter. Residents are urged to avoid unnecessary travel and keep devices charged in case of isolated power outages.
By Thursday afternoon, strong downpours and gusty winds will impact major roadways, including I-295 and US-17. Outdoor activities should be rescheduled or closely monitored for lightning risks. The threat of storms lingers into Thursday night, but daytime impacts pose the greatest risk for traffic delays and flooding in low-lying areas.
Friday will bring mostly sunny skies early, but another round of afternoon thunderstorms is possible as highs reach 94°F. Weekend plans could be interrupted by a 50% chance of showers and storms after 2 p.m. Saturday, with temperatures climbing near 96°F — one of the hottest stretches this month.
Localized flooding, power disruptions, and delays for outdoor events remain a concern, especially for communities along the St. Johns River and near NAS Jacksonville. Stay weather-aware and check for real-time alerts before heading out.
Rain and thunderstorm chances stay elevated through Monday, keeping conditions unsettled into next week. Keep an eye out for additional advisories as more storm activity is possible.
