Here’s my snowfall forecast valid from Friday afternoon through Saturday.

*10 to 13 inches of snow along the North Shore including Two Harbors, Silver Bay, Isabella and Grand Marais.

*7 to 10 inches of snow for Duluth, Superior, Aitkin, Brainerd, Moose Lake and Cloquet.

*4 to 7 inches of snow for Ely, International Falls, Bigfork, Grand Rapids, Walker, Hibbing, Ashland and Hayward.

Energy approaching from the Pacific northwest moves east and will interact with a large pool of moisture across the southern and central Plains.

Low moves east, moisture lifts north, end result will be for widespread snow in the Northland beginning Friday afternoon.
