Jacksonville is starting Labor Day under a muggy, mostly cloudy sky, with temperatures in the mid-70s and a much better chance of rain building through the day. Showers and thunderstorms are expected to become likely from late morning into the afternoon, bringing a cooler high near 86 degrees but a serious risk of slow-moving downpours and localized flooding.
Storms Build Through The Afternoon
Rain chances rise through the morning before peaking around 70% during the early-to-mid afternoon. The strongest coverage is expected between roughly 11 a.m. and 5 p.m., when storms could bring heavy rain, frequent lightning and sudden gusty winds.
The National Weather Service Jacksonville office says the main concern is localized flooding, especially along the coast and in parts of Northeast Florida near and south of the stalled front. Weak steering winds could allow storms to move slowly or repeatedly cross the same neighborhoods, so water may collect quickly on poorly drained streets.
North winds should run about 2 to 9 mph before turning more northeast and becoming breezier near the coast. No watches, warnings or advisories are posted for Jacksonville, but residents should move indoors when thunder is audible and avoid driving through flooded roadways.
Rain Lingers Into Monday Night
Showers and thunderstorms remain likely this evening before gradually becoming more scattered overnight. Monday night will stay mostly cloudy with a low around 76 degrees, and another quarter-inch to half-inch of rain is possible in some areas.
The latest outlook is a cooler and wetter adjustment from earlier holiday-weekend guidance, with the focus now shifting from heat to repeated downpours. Hoodline previously reported on the weekend heat and storm setup.
Storm Chances Continue Through Wednesday
Tuesday brings another chance of showers and thunderstorms, with a high near 85 degrees and rain chances around 60%. Northeast winds could gust as high as 17 mph, and storms may push inland from the coast before becoming more active during the afternoon.
Wednesday looks wetter again, with an 80% chance of showers and thunderstorms and a high near 87. The National Weather Service expects heavy downpours to remain possible as onshore flow continues.
Beachgoers Face Increasing Rip Current Risk
Area beaches have a moderate rip current risk Monday, with the threat expected to increase to high by Wednesday as persistent onshore winds build. Breakers could reach 3 to 5 feet, so swimmers should stay near lifeguards, avoid the water during storms and never enter the surf if conditions look rough.
Temperatures rebound toward the upper 80s and around 90 degrees from Thursday into the weekend, but daily storm chances remain in the forecast. In other words, Jacksonville's holiday weather may cool off, but the umbrellas are not getting the day off.
