"'Polar Vortex' Pushes in for Most of the Nation"

"CHICAGO -- Snow-covered roads, high winds and ice were creating dangerous driving conditions Sunday from the Dakotas to Missouri to Delaware ahead of a 'polar vortex' that'll bring below-zero temperatures not seen in years to much of the nation."

"The counterclockwise-rotating pool of cold, dense air will affect more than half of the continental U.S. throughout Sunday and into Monday and Tuesday, with wind chill warnings stretching from Montana to Alabama. With it comes a startling forecast: 25 below zero in Fargo, N.D., minus 31 in International Falls, Minn., and 15 below in Indianapolis and Chicago.

Several states in the Midwest were getting walloped with up to a foot of new snow, and residents shoveled out and stocked up on groceries before bitterly cold temperatures set in overnight."
