A winter storm is forecast to bring a mix of snow, ice, and wintry precipitation to parts of the Upper Midwest and northern tier of the Northeast this week, potentially causing power outages and hazardous travel conditions. The storm system will track from the West into the northern Great Lakes and Canada, with the most dangerous aspect being the risk of significant ice accumulation on trees and power lines.

Why it matters

Late-season winter weather events can be particularly disruptive, as communities may be less prepared and infrastructure may be more vulnerable after a prolonged period of milder conditions. Power outages from ice storms can leave residents without heat or electricity for extended periods, while heavy, wet snow can also weigh down trees and power lines. Travel disruptions from the storm could impact commuters, businesses, and supply chains in affected regions.

The details

The storm is expected to bring wintry precipitation, including snow and ice, to a swath of territory from eastern South Dakota through Minnesota, Wisconsin, and Michigan's Upper Peninsula starting on Wednesday. Significant ice accumulation of a quarter-inch or more is possible, which can cause widespread tree damage and power outages. In addition, the heavy, wet snow is likely to cling to trees and power lines, further increasing the risk of outages. As the storm system moves into southern Canada over the Easter weekend, a new round of snow and ice is forecast to impact parts of Minnesota, South Dakota, Iowa, Wisconsin, northern Michigan, and northern Maine.

  • The storm system will arrive in the Upper Midwest by Wednesday, March 30.
  • Wintry precipitation, including snow and ice, is expected to spread from eastern South Dakota through Minnesota, Wisconsin, and Michigan's Upper Peninsula on Wednesday night into Thursday, March 31.
  • A second round of snow and ice is forecast to affect parts of Minnesota, South Dakota, Iowa, Wisconsin, northern Michigan, and northern Maine over the Easter weekend, April 5-7.
