Arctic Blast Brings Bitter Cold to the Eastern U.S. from Thursday to Friday

This temperature map video shows the progression of Arctic air gripping the eastern U.S. from Thursday, Feb. 20 at 8 AM EST to Friday, Feb. 21 at 7 PM EST. Frigid temperatures, with wind chills well below freezing, spread from the Midwest into the Northeast and Southeast. The deep freeze extends as far south as the Gulf Coast, with subfreezing temperatures in parts of the Carolinas and Georgia. Warmer air remains over most of Florida, but much of the region faces dangerous cold before a gradual weekend warm-up.
