Jacksonville, FL – Afternoon storms could disrupt travel and July 4th weekend plans across Northeast Florida as a stretch of unsettled weather begins Wednesday. Daily downpours and isolated thunderstorms are expected from midweek through Sunday, bringing potential flash flooding, slick roads, and lightning hazards—especially along I-95 and U.S. 1.
According to the National Weather Service in Jacksonville, storm chances climb sharply by 2 p.m. Wednesday, with gusts reaching 18 mph and rain chances hitting 90%. That trend continues through Thursday and Independence Day, when another round of strong thunderstorms is expected by late afternoon. Rainfall could be heavy at times, with minor flooding possible in low-lying areas.
City-specific impacts will vary: Jacksonville’s Southside and Riverside neighborhoods could see brief street flooding. Beaches and outdoor events are at high risk for weather-related delays. Boaters and beachgoers should monitor marine alerts and be ready to move inland quickly.
Thursday and Friday each carry an 80% chance of thunderstorms, mainly in the afternoon and evening. By Saturday and Sunday, rain chances remain high at 70% as humidity and daytime heating trigger more convection. Temperatures will hover in the upper 80s to near 90°F daily.
Residents are urged to charge devices, limit outdoor plans during peak storm hours (2–8 p.m.), and never drive through flooded roads.
