Jacksonville is waking up to mostly cloudy skies and 75°F on Thursday, May 28, 2026, with muggy air already making it feel sticky. Showers and thunderstorms are likely between about 8 a.m. and 4 p.m., with a high near 89°F and the potential for gusty winds in the stronger cells. Expect brief but heavy downpours that can knock down visibility and slow afternoon commutes.
Afternoon Storms And Flooding Risk
The National Weather Service in Jacksonville expects storms to concentrate along the I-95 corridor and the beaches today, with about an 80% chance of precipitation. Rainfall totals this afternoon are generally forecast to be a quarter to a half-inch, but a wetter pattern through next week could stack up to 3-5 inches overall, with pockets topping 6 inches in a few spots. That kind of repeat action raises the odds of localized street and storm-drain flooding where storms train or stall. Stronger cells may also bring gusty, erratic winds and frequent lightning.
Commute, Beaches And Outdoor Plans
Drivers should plan a little extra time and be ready for short stretches of ponding and sharply reduced visibility under heavier cells. Beachgoers should keep an eye on lifeguard flags and be ready to clear the water quickly if thunder gets close; for context, see our May 25 story on surf and rip-current risk. Anyone organizing outdoor events will likely have better luck shifting activities to the morning hours or moving them under solid cover.
Overnight And Weekend Outlook
Showers and thunderstorms are likely tonight before about 8 p.m., then become more scattered overnight, with a low near 73°F and a chance of patchy downpours. Friday stays unsettled, with highs near 86°F and a 70-90% chance of storms; stronger afternoon cells could dump a half-inch to three-quarters of an inch of rain in a short burst. The soggy pattern is expected to roll through the weekend and into early next week, so repeated rounds of heavy rain and localized flooding remain the main concerns.
Quick Safety Tips
Avoid driving through standing water and head indoors when you hear thunder, since lightning can strike well away from a storm's core. At the beach, swim near lifeguards and follow posted flags, and boaters should check conditions before leaving the harbor. Stay tuned to the National Weather Service and local news outlets for forecast updates and any changes to alerts.
