The National Weather Service has issued an extreme cold warning for much of Minnesota through Thursday morning, with temperatures dipping to 25 degrees below zero in some areas and wind-chill values plummeting to 40 below.

Northwest winds gusting to 25 mph will spur dangerous conditions where frostbite can occur in just 10 or 15 minutes, officials noted.

Thursday morning’s low temperature will hit about 12 below in Duluth, with wind chills overnight in the 30-below range. The extreme-cold warning is for much of St. Louis County, away from Lake Superior, as well as Koochiching, Itasca, Aitkin and counties to the west.

This appears to be the coldest spell of winter, and temperatures won’t rebound much Thursday, with highs below zero across most of the region. Highs will be in the single digits above zero Friday, hit the mid-teens on Saturday and then rise into the upper 20s, above normal, for Sunday and well into next week as another warming trend arrives.

This is on average the end of the Northland’s coldest temperatures of the year, with highs in Duluth bottoming out at about 19 degrees and lows around zero. From now into July average temperatures will continue to rise.

An inch or two of new snow was expected late Wednesday and early Thursday, mostly north of the Iron Range.

The extreme-cold warning is a new advisory for the Weather Service replacing wind-chill warnings. In the Duluth Weather Service area, the extreme-cold warning will be issued when either the air temperature or wind-chill values are forecast to hit 40 below zero. In other areas, warmer temperatures qualify for the new warning.
