Initially, the morning of Sunday, January 27th, a ridge of high pressure was centered across the Upper Midwest. This ridge moved southeast with an area of low pressure developing over Alberta, Canada, and diving southeast across the Dakotas Sunday afternoon, and over northern Iowa, and northern Illinois through Sunday night/Monday morning.
This was a typical Alberta Clipper which raced southeast, with an initial very dry air mass over the Upper Midwest. Thus, moisture content was low, the speed was high, and the atmosphere had to moisten up before snow reached the surface. In addition, the forcing weakened during the afternoon, and evening across southern Minnesota, before intensifying across Wisconsin Sunday night.
These factors limited snowfall amounts with narrow bands of 6 to 8 inches of snow across southern Minnesota, and portions of west central Wisconsin. The heavier amounts, or greater than 8 inches, occurred in southeast Minnesota, and into southern Wisconsin. There were also a few locations in central Minnesota, before the system weakened some, that received 6 to 7 inches of snow from Alexandria to Long Prairie.
The following are some of the heavier snowfall amounts:
7.2 inches in Ellendale.
7.2 inches in Owatonna.
7 inches in Mankato.
6.5 inches near Faribault.
