Jacksonville is waking up to a classic Monday mess on May 11, 2026, with patchy, locally dense fog socking in parts of the metro. Visibility is taking a hit on low-lying roads and bridges, and the morning commute is likely to slow to a crawl in spots. Temperatures started off in the low 70s and are headed for the upper 80s under muggy, mostly cloudy skies. Scattered showers and thunderstorms are expected to pop this afternoon during peak heating, with the best shot at heavier storms late in the day and into the evening. If you have outdoor plans, keep a quick shelter option in mind and be ready for the timing to shuffle around.
Fog And The Morning Commute
The National Weather Service in Jacksonville issued a Special Weather Statement early Monday flagging patchy to locally dense fog from Lake City east along I-10 into the Jacksonville area. Visibility may drop to around a mile or less in some locations. Drivers are urged to use low beams, ease off the gas, and leave extra stopping distance. River corridors, bridges, and shaded streets are the most likely trouble spots. Forecasters expect the fog to lift and thin by mid-morning as the sun climbs and the air mixes out.
Afternoon Storms And Timing
As daytime heating ramps up, scattered showers and thunderstorms are expected to move into the metro between about 1 p.m. and 4 p.m. Storm chances peak roughly between 4 p.m. and 5 p.m., with additional showers and storms possible into Monday night. Forecasters put rain coverage around 50 to 60 percent, with most spots picking up a tenth to a quarter of an inch of rain, and a few neighborhoods seeing heavier downpours. An isolated strong storm could kick out damaging wind gusts, small hail, and frequent lightning, so outdoor events should have a solid backup plan.
Winds, Marine And Beach Safety
Winds stay light to moderate today, but they are expected to turn breezy out of the northeast on Tuesday, with gusts climbing into the 20s of mph near the coast. A Small Craft Advisory may be posted for parts of the local waters late tonight through Tuesday as conditions toughen up for smaller vessels. Rip current risk is also expected to increase Tuesday into Wednesday as the onshore flow strengthens. Boaters should think twice about small-boat trips, and swimmers should stick close to lifeguard stands and listen to posted warnings at area beaches.
What To Do
Plan for a slower-than-usual drive this morning, and keep those low beams on in foggy stretches. Have a rain plan ready for the afternoon, and pay attention to lightning if you are outside. Secure loose patio furniture, tents, and other lightweight gear before gusty bursts roll through, and always check the latest marine forecast before heading out on the water.
