Heavy Snow in Chisago, Minnesota

Six to nine inches of snow was reported across the southern region of the county. Eight and a half inches of snow was measured in Lindstrom, MN.

A troughing pattern over the Pacific Northwest ejected a shortwave trough across the Northern Continental U.S. In the mid-levels of the atmosphere, a defined thermal gradient developed over south-central MN which progressed northward into central MN. Forcing for snowfall development was maximized along a narrow band extending from Stearns County to northern Washington County. This forcing led to heavy snowfall rates exceeding one inch per hour with six to eight inches of snow accumulations.

Highest snowfall observations for this event were:

8.5 inches in Lindstrom, MN

8.0 inches 7 miles SE of St. Cloud, MN

7.5 inches in Saint Francis, MN

7.0 inches 5 SW of Isanti, MN

6.0 inches 3 W of Marine on the St. Croix, MN.
