The temperature at Jacksonville International Airport dropped to 37.9 degrees at 4:56 a.m., marking the chilliest reading of the season so far. The wind chill at the Northside airport made it feel even colder, dipping to 33 degrees.

The cold front sweeping across the Sunshine State brought some of the lowest temperatures seen since last winter, a sharp turn for a region accustomed to mild fall weather. The overnight chill caught many off guard, with residents reaching for heavy coats and turning up the heat.

The cold snap is part of a broader pattern of unseasonably cold air moving through Florida, though forecasters expect temperatures to moderate as the day progresses. Still, the early-morning low serves as a reminder that winter is approaching, and local officials are urging residents to take precautions, particularly for vulnerable populations and pets.

For a community that prides itself on outdoor living, the brief freeze is a test of resilience—and a signal that the region's mild climate is not immune to the broader shifts in weather patterns that have brought more extreme temperature swings in recent years.
