A rare and historic May snowstorm continues to pelt Iowa, Minnesota, and Wisconsin with snowfall amounts unprecedented in the historical record for the month of May. Winter Storm Achilles has brought 15.5" of snow to Owatonna, Minnesota, about 50 miles south of Minneapolis. This is (unofficially) the largest May snowstorm in state history, surpassing the 3-day total of a 15" snowstorm at Sandy Lake Dam/Libby. The 14.7" of snow that has fallen at Baldwin, Wisconsin is just shy of Wisconsin's May state record snowfall of 15.4". Minneapolis just missed getting heavy snow, as bands of heavy snow with thunder and snowfall rates over one inch per hour set up over Northeast Iowa and Southeast Minnesota early this morning. There are multiple reports of tree damage across Red Wing, Owatonna, and other locations in eastern Minnesota and western Wisconsin, with power outages in the thousands across the Red Wing area. I-35 is closed in both directions just north of Owatonna due to snow cover and downed power lines.
Here are the latest peak snowfall totals by state as of early Thursday morning:
• Buckhorn Mtn., Colo.: 28.2"
• Near Buford, Wyo.: 20"
• Near Harrisburg, Neb.: 6.1"
• Ringsted, Iowa: 6.5"
• Owatonna, Minn.: 15.5"
• Beresford, S.D.: 6"
• Baldwin, Wisc.: 14.7"
