January 20, 2012 Snowfall


A quick moving weather system dumped a swath of snow over much of the region on Friday, January 20, 2012. Snow moved in across southern Minnesota and northeast Iowa near daybreak and across the rest of the area during the day. The snow began moving out by early afternoon west of the Mississippi River and by the evening hours in western Wisconsin.

Amounts of 3 to 6 inches were common south of Interstate 90, with generally less than 3 inches further to the north across Minnesota and Wisconsin. There was very little wind and the snow was dry.

Below is a snowfall total map for January 20th and a specific amount listing is below that.
