Heavy snow developed across South Dakota and northwest Iowa and advanced northeastward during the day February 24, 2018.  Snowfall rates of 1 to 2 inches per hour were common.  The snow tapered off from southwest to northeast during the evening, and ended in Wisconsin in the early morning hours of February 25th.

Snow accumulations of 5 to 9 inches were reported across central Minnesota.  Lesser amounts in the 3 to 6 inch range were measured across southern Minnesota and western Wisconsin where snow mixed with freezing rain and sleet at times.  The map below is smoothed and therefore does not show the several localized 8 or 9 inch totals reported.
