An arctic air mass sprawling across the eastern, central and parts of the western U.S. on Monday will channel temperatures 20-30 degrees below already historically cold January averages and was poised to slam parts of the South with a disruptive winter storm.

Snow and ice may bring major travel disruptions and power outages in the South starting Monday evening, forecasters warned.
