A band of wind-driven snow lifted north and northeastward across Minnesota on the evening of Sunday, December 26th, with the snow intensifying and expanding over the northern half of the state. The snow became especially heavy late in the evening near Brainerd, where a spotter had reported 3.5 inches accumulating in one hour. Multiple waves of heavy snow then paraded over the Brainerd Lakes, Grand Rapids, Duluth, and the North Shore of Lake Superior, eventually winding down during the afternoon of Monday, December 27th. Strong winds off of Lake Superior led to blizzard conditions along the North Shore and into Duluth. A corridor of widespread snow totals of 8-12 inches was observed with the Brainerd Lakes region climbing near 18 inches.
