The coldest air mass since December 2016 surged southward across the northern part of the nation during the last part of December.

The coldest wind chills occurred in west central Minnesota where values dropped to 45 degrees below zero. There was a small window Saturday afternoon, December 30th where wind chill values rose above -35F; it was temporary as wind speeds increased Saturday night, causing wind chill values to once again fall below -35F.
