The episode as NWS MPX wrote it up.
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.
