JACKSONVILLE, Fla. – Warm air clings to North Florida this morning, but signs of a sharp seasonal turn are already in motion. Fog drapes over stretches of I-10 and U.S. 301, thick enough in spots to slow early traffic near river crossings and low-lying marshes. The stillness won’t last long — by late Monday, a strong front will sweep through, bringing a clear sky and the coldest air of the season.
According to the National Weather Service in Jacksonville, dense fog will linger through midmorning before sunshine returns and temperatures surge into the mid-80s. A few brief showers or isolated thunderstorms could flare near the coast later today, followed by gusty winds and a dramatic cooldown. By Monday afternoon, winds will shift northwest at 15 to 25 mph as cooler, drier air spills in from Georgia and the Panhandle.
Temperatures will plummet Monday night into the low 30s inland and upper 30s along the St. Johns River basin. Patchy frost may form early Tuesday, particularly west of I-95 near Lake City, Baldwin, and Starke. Veterans Day will dawn bright but brisk — highs struggle to reach the mid-50s under a crisp blue sky.
Gardeners and homeowners should protect tender plants and cover outdoor pipes where possible. Pet owners are urged to bring animals indoors during Tuesday’s chilly dawn hours.
By midweek, sunshine dominates again with moderating temperatures in the upper 60s and low 70s. For now, it’s a full November weather pivot — from muggy warmth to jacket weather in just 36 hours, signaling the Sunshine State’s first real fall-to-winter transition.
