A blast of genuine winter weather is aiming at Upper Michigan. It will bring arctic cold to all of the Upper Great Lakes along with heavy snow over parts of Upper Michigan.
A Lake Effect Snow Watch has been issued by the National Weather Service (NWS) for late Friday night through Saturday night for all of the northern U.P. and a small section of southeastern Upper Michigan. An arctic cold front will pass through during Friday night. Very cold air flowing across Lake Superior will produce an initial band of heavy snow along the front. Then lake-effect snow will fall along with blowing and drifting due to strong and gusty north to northwesterly winds.
The heaviest snows on the west end are expected in the higher elevations, especially in Ontonagon to Gogebic Counties where 10 inches or more are possible. Farther east, significant accumulations will fall over north-central into eastern Upper Michigan. The heaviest snow will likely fall over much of Alger County; there, a foot or more is possible. The northwesterly wind will drive snow bands far to the south. That means much of Schoolcraft County is in the watch. Even places like Manistique will probably see a significant snowfall before the weekend is over.
Even where it does not snow much, the cold will make headlines. Daytime highs both Saturday and Sunday are likely to stay in the teens over much of Upper Michigan.
