JACKSONVILLE, FL – The city wakes under a gray veil this early Friday as thick fog rolls across the St. Johns River. Streetlights blur, headlights glow dull through the mist, and visibility dips to just a few hundred feet in spots from Baldwin to Amelia Island. It’s a quiet but potentially hazardous start across northeast Florida.
According to the National Weather Service in Jacksonville, dense fog is developing across inland and coastal counties, including Nassau, Duval, Clay, and St. Johns, with visibility occasionally dropping below one-quarter mile. Drivers on I-10, I-95, and U.S. 301 should allow extra time for reduced visibility and slow-moving traffic through the early morning hours. The fog is expected to lift gradually by mid-morning as sunshine breaks through.
Once the haze clears, much warmer air will surge in. Highs will climb into the lower 80s today and continue through the weekend, offering a stretch of near-summer warmth before the next change Sunday. Light winds today turn southwesterly Saturday, pushing inland temperatures to the mid-80s. A weak front will approach late Sunday, bringing a 20% chance of showers or isolated thunderstorms, mainly west of Jacksonville. Any rainfall will be brief, but gusty winds could accompany stronger cells along I-75 and the Suwannee Valley.
By early next week, drier and cooler air moves in behind the front. Monday and Veterans Day look breezy and bright with highs in the 60s. Longer-range trends suggest another warm-to-cool shift mid-November — a pattern that could hint at Florida’s first early winter cooldown before Thanksgiving.
