Polar vortex to bring prolonged, life-threatening cold outbreak to midwestern US this week

The coldest weather in years will put millions of people and animals throughout the midwestern United States at risk for frostbite to occur in minutes and hypothermia during the final days of January.

The deep freeze continued across the Upper Midwest on Sunday with temperatures plummeting well below zero in the morning. The low of 45 below zero F in International Falls, Minnesota, shattered the day’s record of 36 below zero F from 1966.
