Florida – Clear skies stretch over Jacksonville this morning as a light north breeze drifts across lawns and parking lots, setting up a mild early-December pattern that shifts quickly through the weekend. Sunlight stays bright, but subtle changes are already underway as warmer southern flow begins rebuilding ahead of Saturday’s jump into the low 70s.

According to the National Weather Service, temperatures rise toward 67°F today with only a gentle wind shifting south by afternoon. Roads stay dry, and visibility remains wide open—ideal weather for early holiday travel, decorating, or outdoor errands before the weekend’s wind shift tightens conditions.

Meteorologists now track a warmer pocket of air sliding into Northeast Florida on Saturday. Highs reach the low 70s, and skies stay mostly sunny. To be fair, it will feel more like late fall than early winter, but the warmth doesn’t last. A cooler, breezier push arrives Sunday, dropping highs to the lower 70s with a sharp evening fall into the 30s across inland areas.

That quick cool-down may surprise travelers returning home late Sunday. Gusts strengthen from the northwest, and temperatures tumble enough to bring a crisp December bite—especially along exposed stretches of I-295 and the St. Johns River bridges. While winter hazards like black ice remain unlikely here, Floridians should watch for rapid cool-downs that challenge evening outdoor plans.

Monday stays bright but noticeably cooler with highs in the low 50s, a reminder that winter patterns are edging south even if the state remains frost-free for now.
