Extreme Cold/Wind Chill in Southern Aitkin, Minnesota

The last night of the arctic outbreak was once again widespread, affecting almost all of the Northland. High pressure was in place over the region leading to optimized radiational cooling conditions and the slightest breeze of wind was enough to send wind chills into dangerous criteria. Air temperatures dropped into the 30s and 40s below zero once again with wind chills as low as -51F. This was the ninth and final night of an arctic outbreak across the region that lasted over a week.
