| On November 10, 1940, a weak low pressure system (ahead of the Armistice Day low pressure system) began to produce light snow across northern and western Minnesota, and northern Wisconsin. The snow rates then rapidly increased on the morning of November 11th as a much stronger low pressure system moved from Kansas City, MO to just north of La Crosse, WI. The heavy snow then continued to fall into the afternoon into the morning of November 12th as the low pressure system continued to strengthen and move slowly northeast into northern Ontario. In addition to the snow, 30 to 50 mph winds caused considerable blowing and drifting of snow which trapped unsuspecting motorists.
In Iowa, the snow was mainly confined to the western and northern parts of the state. The highest snow total was 13 inches in Cushing. Additional snow amounts across the state, including a map, can be found by clicking here. In Minnesota, the heaviest snow fell from southwest and south central parts of the state northeast into the Arrowhead. The highest snow total was 26.6 inches Collegeville. Additional snow amounts across the state, including a map, can be found by clicking here. In Wisconsin, the heaviest snow fell across the western and northern parts of the state. The highest snow total was 19 inches six miles north of Bayfield. Additional snow amounts across the state, including a map, can be found by clicking here. |
