Record Cold Continues, Relief by Week's End

An arctic air mass will continue to linger over the Deep South today, keeping temperatures across Florida well below normal. Temperatures at or below freezing this morning will continue until around 9 or 10 am. Some locations across North Florida may experience freezing temperatures through noon. Freeze warnings remain in effect for nearly the entire state through the mid morning.

Highs this afternoon will reach only into the mid 40s over the northern half of the state, with only low to mid 50s expected further south. Breezy north-northwest winds of 10-15 mph will make conditions feel much colder, especially during the morning, as wind chills will range from the teens over the north to lower 20s in the south. Wind Chill Advisories and Wind Chill Warnings are in effect for nearly the entire state, including the Keys.

Tonight, Freeze Watches and Freeze Warnings continue as freezing temperatures will once again reach as far south as the South Florida mainland. Lows are forecast to drop into the upper teens to low 20s from the Panhandle to North Central Florida, with mid to upper 20s forecast for the remainder of Central Florida southward into interior South Florida.

Temperatures in the Keys are forecast to dip into the low to mid 40s. Locations along the immediate coast will be slightly warmer; however, a brief period of temperatures at or below freezing cannot be completely ruled out. Durations of sub-freezing temperatures will be around 12-14 hours across North Florida, 6-12 hours across Central Florida, and 3-6 hours across South Florida.

Hard Freeze conditions could harm or kill vegetation, exposed pipes, automobiles and any small to medium animals that remain outdoors. Please use the 5-P's of cold weather safety.
Along with the colder air mass, conditions will continue to be very dry and conducive to the spread of wildfires. Red Flag Warnings have been issued for all of Florida, except for the Keys, due to critically low relative humidity and breezy winds.
