A storm system began to develop across the Plains and into the Upper Midwest Saturday morning, December 10th. Initially, a dry air mass to the north kept the onset of light snow confined to the Minnesota, Iowa border through noon. By the afternoon, the area of light snow slowly expanded northeast across southern Minnesota, and far west central Wisconsin.
Although the light snow continued through the late afternoon across southern Minnesota, snowfall amounts were light and averaging under 1-2 inches in a 6-12 hour period. By the late afternoon and early evening, a band of heavier snowfall developed across far southern Minnesota between Redwood Falls, and Faribault. This band of snow slowly moved northward and held relatively stationary through the evening, and overnight hours before tapering off Sunday morning. This band generated snowfall rates of 1/2 to 1 inch per hour and caused a small area of snowfall amounts between 6 to 10 inches from west central, to southeast Minnesota. The heaviest occurred near Redwood Falls and Granite Falls, with a secondary area of 8 to 10 inches near New Prague and Montgomery. The snow tapered off from west to east Sunday morning after 9 am, and by early afternoon most of the snow had ended with only flurries reported.
A few counties in southern Minnesota had between 6-8 inches of snow by midnight, Sunday, December 11th in a 12 hour period, as most of the snow began Saturday morning.  Totals of 8 to 10 inches fell in a 24 hour period across the rest of southern Minnesota as a few inches occurred Saturday, with the bulk of the snowfall between 9 pm and 9 am.
The heaviest snowfall from this storm include:
Redwood Falls 12.1 inches.
Montgomery 11 inches.
Granite Falls 10 inches
Canby 10 inches.
