  • Dangerous conditions will continue across eastern Minnesota, North Shore and portions of northwest Wisconsin this evening due to the falling snow which will be heavy at times along with widespread blowing and drifting snow causing whiteout conditions. Avoid travel if you can!
  • Strong NW winds will continue across the Northland tonight with winds of 15 to 30 mph with gusts to 50 mph. A few power outages are possible tonight due to the high winds.

  • Wind chills of 15 below to 30 below zero are likely tonight into Thursday morning.
  • Snow will gradually taper off to light snow and flurries from SW-NE across the Northland by mid to late evening and into early Thursday morning, but heavier lake effect snow should continue into Thursday morning along the South Shore of Lake Superior in northern Wisconsin.
