Jacksonville is waking up to a muggy, mostly cloudy Sunday before temperatures climb near 93 degrees. The heat index could reach 103, and afternoon thunderstorms are expected to bring a sharper turn in the weather after a hot start. Some storms may be strong enough to produce damaging wind gusts, lightning and brief flooding rain.
Storm Risk Builds After Lunch
The latest update from National Weather Service Jacksonville puts the first shower and thunderstorm chances between 1 and 4 p.m., followed by more likely storms through the afternoon and evening. Rain chances rise to 60%, with roughly a quarter- to half-inch of rain possible in Jacksonville.
The strongest storms could bring sudden downburst winds and locally heavy rain, with activity potentially lingering after sunset. No watches, warnings or advisories are currently posted for the Jacksonville area, but residents should have a way to receive alerts and move indoors quickly if thunder roars.
Labor Day Looks Cooler And Wetter
Monday brings some relief from the heat, with a high near 88 degrees, but the forecast is much wetter. Showers and thunderstorms are likely throughout the day, with a 90% chance of rain and another half-inch to three-quarters of an inch possible.
Tuesday stays unsettled with a high near 87 and a 70% chance of showers and thunderstorms, while Wednesday remains stormy with a high near 88. The forecast turns a little warmer by Thursday, reaching about 90 degrees, but afternoon thunderstorms remain likely.
Beachgoers Should Watch The Water
Northeast Florida beaches face a moderate rip current risk this weekend, even as storms add another reason to keep an eye on the sky. Swimmers should stay near lifeguards, avoid entering the water during storms and wait at least 30 minutes after the last thunder before returning outdoors.
Sunday's stronger-storm concern is a notable update to the holiday-weekend pattern outlined in Hoodline's earlier forecast. For Jacksonville, the practical plan is simple: get outdoor errands done early, keep the umbrella nearby and treat the afternoon sky as a changing situation.
