An extended period of snow fell across southeast Minnesota from December 16th into the 17th. Accumulations generally ranged from 4 to 7 inches. As the snow was ending, northwest winds increased into the 15 to 25 mph range that produced plenty of drifting snow along with some visibility reductions from blowing snow. Once the snow ended, cold air poured into the region and when combined with the winds, produced dangerously cold wind chills. Values of 25 to 40 below zero were common from the evening of December 17th into the morning of the 18th.
