Florida – Warm sunshine already pours over Jacksonville streets this morning, and the air feels more like early June than early March. Temperatures surge toward 90°F today, but a surge of moisture arriving soon will spark thunderstorms and soaking showers across northeast Florida before Friday.
According to the National Weather Service in Jacksonville, clear skies dominate early with light south winds increasing to 5–10 mph by late morning. Afternoon highs climb near 90°F, an unusually warm level for mid-March across Duval County.
Clouds increase later tonight as humidity builds. Temperatures remain mild near 67°F, creating the unstable setup that fuels tomorrow’s storms.
By Thursday morning, showers begin forming west of Jacksonville before spreading across the region. Rain chances climb to nearly 90 percent during the afternoon as thunderstorms develop across northeast Florida.
Meteorologists warn that brief downpours and lightning could disrupt travel along I-95, I-295, and the Arlington Expressway. Winds may gust to 22 mph, and heavier showers could briefly reduce visibility.
Keep umbrellas nearby and allow extra time if traveling through downtown Jacksonville or toward the beaches.
Conditions begin improving later Thursday evening as rain gradually moves offshore. Cooler air filters in behind the system.
Friday feels noticeably different. Sunshine returns with highs near 74°F and lighter winds, offering a comfortable break after the stormy stretch.
Another unsettled pattern develops this weekend. Scattered showers may redevelop Saturday afternoon, while a stronger round of rain and thunderstorms becomes possible Sunday during peak spring break travel across Florida highways and airports.
Long-range outlooks hint at continued warmth across the Southeast heading deeper into March as spring officially arrives on March 20.
