NEW YORK — The coldest air of the early winter season is blasting the eastern U.S. Monday with single-digit temperatures with the wind chill, as the Polar Vortex unravels and with it, brings dangerous arctic air to millions from New England to the Gulf Coast.
For those in the Northeast and Midwest, this comes on the heels of a fast-moving winter storm this weekend, with subzero temperatures set to freeze leftover snow during the morning and afternoon commutes.

Meanwhile, most of the Southeastern U.S. is under a Cold Weather Alert Monday morning with temperatures in the teens, factoring in the wind chill, just six days ahead of the start of astronomical winter on Sunday.
