  • Timing: Tuesday through Wednesday
  • Precipitation types and locations: Snow or rain changing to snow from South Dakota to Nebraska through Tuesday evening. Snow increases across northern/central Minnesota, northern Wisconsin and Upper Michigan into Tuesday night. Parts of southern Minnesota and northwest Iowa may transition from rain or sleet to snow Tuesday into Tuesday night, including Minneapolis-St. Paul. By Wednesday, snow lingers from eastern Minnesota to Wisconsin and Upper Michigan.
  • How much snow? Accumulations of 5 inches or more expected in a narrow zone from northeastern South Dakota to central/northeast Minnesota (mainly north and northwest of the Twin Cities), northern Wisconsin and western Upper Michigan. Some areas could see storm totals close to a foot. More than 6 inches of snow in the Black Hills of South Dakota. Lighter amounts elsewhere.
  • Impacts: Poor travel conditions likely Tuesday through early Wednesday throughout the affected areas. Flight delays possible at Minneapolis-St. Paul International Airport.
  • Winds: Strong north winds will continue on the backside of the storm through the Plains on Tuesday, from the Dakotas, Wyoming and Colorado to Kansas and Oklahoma. Wind gusts over 40 or 50 mph are likely. These winds could combine with snow in South Dakota and Nebraska to produce poor visibility and dangerous travel conditions. Northeast winds of 10 to 20 mph could accompany snow in Minnesota, leading to reduced visibility.
