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.
