Snow through late this evening, winter weather advisory in effect

3:30 PM 10/20/2020 – This post will focus on the ongoing snow event which will continue into tonight, but I’ll have another post shortly regarding Thursday’s storm, and possibly another one for this weekend.

Still looks like a widespread 2 to 5 inch snowfall across much of the Northland through late tonight with the greatest amounts extending from the Brainerd Lakes to the North Shore (higher terrain) and northwest Wisconsin.

Plan on slippery road conditions through Wednesday morning. Slow down and use caution while traveling.

Note: Record snowfall at Duluth for October 20th is 3.4 inches set in 1936. We have a shot at breaking this record!
