Possible fog and stratus are forecast early Wednesday in Jacksonville, with the city expected to reach about 88 degrees. A slight chance of showers is forecast from 1 to 2 p.m., followed by a slight chance of showers and thunderstorms after 2 p.m.

East Winds Pick Up By Afternoon

The National Weather Service Jacksonville forecast puts the rain chance at 30%, with scattered showers and embedded storms possible over northeast Florida during the afternoon. Storms could produce locally heavy rainfall.

No watches or warnings are listed for Jacksonville. Along the Atlantic coast, temperatures may stay a little cooler than inland neighborhoods, but the humidity will keep the afternoon feeling like a full return to summer.

Thursday And Friday Turn More Stormy

Thursday repeats the 87-degree pattern with a 30% chance of afternoon showers and thunderstorms. Friday is the more unsettled day, with storms likely after 2 p.m. and a 60% rain chance, while overnight temperatures remain in the mid-70s.

Saturday may reach near 88, while Sunday is expected to be cooler, around the lower 80s. Rain chances stay elevated: 40% Saturday and 60% Sunday, when storms become more likely later in the day. It is the latest turn in a stormier stretch.

Cooler, Wetter Pattern Arrives Monday

Tuesday brings highs across northeast Florida in the upper 70s to low 80s, alongside strong northeasterly winds and waves of showers.

For Jacksonville residents, Wednesday offers a decent outdoor window before storms become more common, while anyone planning early-next-week activities should keep rain gear and a flexible schedule handy. The current forecast lists no weather advisories, but conditions can change as the wetter pattern approaches.
