A narrow but intense band of snow set up across portions of southeast Minnesota during the evening hours of May 1st and continued into the 2nd. While all of southeast Minnesota ended up receiving some snow from this system, snow was heaviest in a band between Mason City, Iowa and Menomonie, WI where over 10 inches fell.  Amounts exceeded 15 inches over portions of Olmsted and Dodge Counties. New Minnesota state snowfall records for the month of May were established with a one day total of 15.4 inches on May 2nd and two day total of 17.2 on May 2nd and 3rd in Dodge Center (Dodge County). Other notable snowfall totals were 16.6 inches just west of Rochester (Olmsted County) and 14 inches in Grand Meadow (Mower County). The heavy wet snow caused several power outages to occur, as 10,000 customers in Rochester lost power while over 1,700 customers were without power across parts of Mower, Dodge, Fillmore, Wabasha, Winona and rural Olmsted Counties. The weight of the snow caused some buildings and barns to collapse and hundreds of trees across the region were damaged. Numerous schools across southeast Minnesota canceled classes and the Minnesota DOT did not recommend travel on Interstate 90 east of Albert Lea and on state highways.
