Marquette, Michigan – Lake-effect snow showers are expected to impact portions of Michigan’s Upper Peninsula today, bringing several inches of snow and difficult travel conditions, especially in the eastern U.P.
According to the National Weather Service in Marquette, moderate lake-effect snow is forecast to develop across the northwest wind snowbelts, with the heaviest accumulations expected east of Marquette. Snowfall totals of 2 to 5 inches are possible in parts of Alger and Luce counties, including areas near Munising and Grand Marais. Lighter amounts of 1 to 4 inches are expected farther west toward Marquette and Newberry.
Visibility may be reduced to one-half mile or less at times in heavier snow showers, particularly along exposed stretches of US-41, M-28, and H-58. Breezy conditions with wind gusts up to 35 mph will contribute to blowing and drifting snow, especially closer to Lake Superior, making travel conditions change rapidly over short distances.
Temperatures will remain well below normal, with daytime highs only reaching the single digits to teens. Overnight lows are expected to fall into the single digits above and below zero, with the coldest conditions occurring across interior sections of the Upper Peninsula. The combination of cold temperatures and wind will lead to bitter wind chills.
The National Weather Service noted that lake-effect snow showers are expected to continue into tonight and possibly into Thursday, though the heavier snow bands may gradually shift westward as winds change. Even where snowfall amounts are lower, untreated roads may remain snow-covered and slick due to persistent cold.
Commuters, students, and delivery drivers traveling along major corridors such as US-41 and M-28 should allow extra time and be prepared for rapidly changing conditions. Officials urge motorists to carry winter safety supplies and check road conditions before traveling.
