Wider weather episode

A slow moving, deepening area of low pressure located over the Upper Peninsula of Michigan affected the Northland on the 16th into the 17th bringing a period of freezing rain before changing over to snow. Areas closer to the low in northwest Wisconsin received the brunt of the snow, but pockets of heavier snowfall to 6 to 8 inches were reported downwind of Lake Superior due to lake enhancement. As the low deepened the night of the 16th into the 17th, gusty winds led to a period of blizzard conditions along the North Shore of Lake Superior during the morning of the 17th.
