Marquette, Michigan – Lake-effect snow continues to hammer western and north-central Upper Michigan today, with travel conditions expected to turn increasingly dangerous Sunday night into Monday as winds strengthen and temperatures plunge. Roads across the western U.P. are already snow-covered, and conditions are expected to deteriorate rapidly after dark.
According to the National Weather Service in Marquette, periods of moderate to occasionally heavy lake-effect snow will persist today across the Keweenaw Peninsula and portions of Baraga and Marquette counties. Winter Weather Advisories remain in effect through this evening, with Winter Storm Warnings posted for parts of the western U.P. Snow accumulations continue to build, especially in favored snow belts.
By Sunday night, snow is expected to become lighter and more powdery, making it highly susceptible to blowing and drifting. Winds increasing to 20 to 45 mph will lead to sharply reduced visibility and hazardous travel, particularly along exposed stretches of US-41, M-26, and M-28. Whiteout conditions will be possible at times.
Communities including Houghton, Hancock, L’Anse, Marquette, Ironwood, and Watersmeet may see rapidly changing road conditions as snow bands shift and blowing snow intensifies. Travel impacts are expected to be most severe Sunday night and Monday.
The cold intensifies as well, with dangerously low wind chills developing Sunday night into Tuesday. Residents are urged to avoid unnecessary travel, prepare for extreme cold, and monitor updates closely as winter headlines remain in effect and conditions evolve.
