On the heels of a significant early season winter storm that produced more than a foot of Lake Effect snow in Ohio yesterday and prompted Tornado Warnings in New Jersey on Monday, very cold air is pushing deep into the southeastern United States, with readings in the 20’s, 30’s, and 40’s oozing south into the Florida peninsula.

Due to the cold weather, the National Weather Service in Jacksonville, Florida has issued a Frost Advisory for tonight from 3am to 8am for portions of southeast Georgia and northeast and northern Florida. Frost in this area could kill sensitive outdoor vegetation if left uncovered.

While a frost and freeze isn’t expected across central and southern Florida, conditions will still be cold.  Crystal River should dip down to 35 while Tampa drops to 46. Fort Meyers is expected to dip to 49 by sunrise tomorrow. Even Miami, a city known for year-round warmth, will dip down to a relatively chilly 67.

While the sun will be out during the day for the balance of today and tomorrow, conditions will be breezy across south Florida. Those breezes will make the chilly air feel even colder than it really is.

Temperatures are forecast to recover tomorrow …before they fall again on Saturday as another frontal system approaches the Sunshine state.

Meteorological winter officially began yesterday in the U.S..
