Marquette, MI – Lake effect snow will bring up to 7 inches across parts of Michigan’s Upper Peninsula through Sunday night, reducing visibility and impacting travel.
According to the National Weather Service in Marquette, ongoing light snow will transition to pure lake effect snow tonight as colder air settles over Lake Superior. The heaviest accumulations are expected across the north-central Upper Peninsula, the Keweenaw Peninsula, and higher terrain areas of the western UP.
Snowfall totals between 3 and 7 inches are forecast in the most persistent lake effect bands, including areas near Houghton, L’Anse, Marquette, and Copper Harbor. Lower totals are expected farther east.
Gusty northerly winds will contribute to blowing snow and areas of very low visibility, especially along M-28 between Marquette and Munising beginning Sunday morning. Travel conditions may deteriorate quickly in heavier snow bands.
Winter Weather Advisories have been extended for north-central and Keweenaw counties through Sunday. A current advisory in Delta County expires at 7 p.m. EST tonight, while new advisories for Ontonagon and Gogebic counties begin at 10 p.m. EST.
The snow is expected to taper late Sunday night as lake effect bands weaken.
Drivers across the Upper Peninsula are urged to allow extra travel time and prepare for changing road conditions.
