Jacksonville woke Thursday to partly cloudy skies and muggy air near 80 degrees, but the quieter start will not last. Showers and thunderstorms are expected to build after 10 a.m., with a high near 89, heat-index values up to 102 and gusty east winds that could reach 24 mph.
The National Weather Service in Jacksonville puts the chance of rain at 50% for Thursday, with the best odds from late morning through the afternoon. Rainfall will generally be light, but a few storms could produce brief heavy downpours, lightning and sudden wind gusts, with about a tenth to a quarter-inch of rain possible.
Storms And Gusty Winds Build Through The Afternoon
Temperatures should peak around midday before slipping into the mid-80s as clouds and rain spread across the area. East winds will run 6 to 16 mph, with gusts as high as 24 mph, so drivers should watch for ponding water and sharply reduced visibility beneath heavier cells.
Thursday night remains mostly cloudy, with a chance of showers and thunderstorms, a low near 77 and southeast winds gusting as high as 23 mph. The unsettled pattern is expected to continue into Friday, when showers and thunderstorms become likely and the heat index could reach 106.
High Rip Current Risk Continues At Northeast Florida Beaches
Beachgoers face a high risk of dangerous rip currents through Thursday evening along Northeast Florida beaches. The advisory remains in effect through 8 p.m., and the safest choice is to swim near a lifeguard, avoid the water during storms and never try to overpower a rip current by swimming straight toward shore.
If caught in a rip current, the National Weather Service advises swimmers to stay calm and float, then move parallel to the shoreline until free of the current. Anyone unable to escape should face the beach and signal for help.
Storm Chances Stay Elevated Through Labor Day
Friday and Saturday both bring highs near 91 with a 60% chance of showers and thunderstorms, while Sunday reaches about 92 with storms likely. Labor Day looks slightly cooler near 88, but the chance of rain rises to 80%, making indoor backup plans a smart addition to cookouts, beach trips and outdoor errands.
The latest update sharpens the beach safety picture from Hoodline’s earlier forecast, with the rip-current threat now elevated and heavier rain potential focused on Thursday and Friday. Thunderstorms may be routine for late summer, but lightning, flooding and fast-changing beach conditions are not worth gambling on.
