Overview

A winter storm affected all of Upper Michigan the weekend of January 18-19, 2020. Light snow began late Friday night January 17, then became heavy over central and eastern parts of Upper Michigan the following morning. Snowfall rates of 1-2 inches per hour were observed in many locations. Lake-enhancement from Lake Michigan also contributed to heavier snowfall rates in areas downwind of the lake.

Snow tapered off Saturday afternoon in most areas, but transitioned to lake-effect snow bands in the north wind snow belts that continued through Saturday night. The highest snow amounts were on the Keweenaw Peninsula where east wind contributed to lake enhancement Saturday morning, and then lake-effect continued through Saturday night. Higher totals were also observed along the rest of the western shore of Upper Michigan down to Ironwood.
