What happened
The episode as NWS MQT wrote it up.
A pool of cold Canadian air was centered just north of Lake Superior as a low pressure system tracked from southern Minnesota across Wisconsin, lower Michigan and into Quebec. Precipitation started as light freezing drizzle but soon turned to snow with the arrival of the colder air. As the system moved east, most of the Upper Peninsula received from 3 to 5 inches of system snow. Northeast winds behind the low generated lake effect snow squalls along the south shore of Lake Superior with the heaviest accumulations over the north central Upper Peninsula and the Keweenaw Peninsula. Storm totals include 17 inches at the Marquette County Airport, 16 inches at Phoenix, 14 inches at the Houghton County Airport and 10 inches at Witch Lake.
