Florida – Frost coats rooftops and parked cars this morning as cold air presses deep into northeast Florida. Breath hangs in the air, lawns crunch underfoot, and temperatures hover near freezing as a rare winter chill settles in fast.
According to the National Weather Service in Jacksonville, a Freeze Warning and Cold Weather Advisory remain in effect through mid-morning. Sub-freezing temperatures have dipped as low as 24 degrees inland, with wind chills falling into the low 20s before sunrise. These conditions pose risks to people, pets, plants, and exposed pipes.
Across Duval, Clay, Nassau, and St. Johns counties, residents are waking to one of the coldest mornings of the season. In Jacksonville, frost is widespread, especially away from the immediate coast. Drivers may encounter slick spots on bridges and overpasses where condensation froze before dawn.
Temperatures rebound quickly later today under full sunshine. Highs climb into the mid-50s, easing cold stress but not eliminating concerns. Sensitive plants damaged this morning will not recover, and unprotected pipes remain vulnerable during future cold nights.
Cold air lingers into the weekend. Saturday stays mild during the day, near 60, but another cold night follows. By early Sunday, temperatures again drop into the low 30s, with frost likely inland. Patchy showers arrive Sunday afternoon, followed by another cold push Sunday night.
MLK Day looks dry and pleasant during the afternoon, with highs near 55. However, early morning frost remains possible, especially in rural areas. The pattern stays active into next week, with repeated cold mornings across north Florida.
Residents should continue cold-weather precautions. Protect pipes, cover plants, bring pets indoors, and check on neighbors sensitive to cold.
