Parts of the U.S. may see days of record-low temperatures beginning Sunday as forecasters expect a deep freeze to bring wind chill as low as 65 below zero in parts of the Midwest. Temperatures will hover around zero throughout the East Coast region early next week.
"It's going to be very cold and the wind chills are going to be very low," said Bob Oravec, a forecaster with the National Weather Service. "It hasn't been this cold in several decades for the big East Coast cities."
Parts of the Upper Midwest -- such as Minnesota, North Dakota, South Dakota, Wisconsin and Montana -- will get hit hardest, he said. Many of these areas have wind chill advisories.
