Extreme Cold/Wind Chill in Southern Itasca, Minnesota

Wind chills fell to -41F at the Grand Rapids airport during the early morning hours of the 23rd.

This was the second phase of a winter storm that affected the region in the days leading up to the Christmas holiday. As the area of low pressure began to move away from the region, cold air spilled into the region from Canada. A pressure gradient remained over the region as well that kept winds from diminishing overnight. This led to dangerously cold wind chills as low as -43F across parts of northeastern Minnesota the morning of the 23rd.
