Marquette, MI – Light snow falls across Upper Michigan this morning as a cold north wind sweeps in from Lake Superior, signaling another round of steady winter weather. Gusts up to 30 mph are pushing snow bands inland, covering highways and rural roads in a patchy white haze. Drivers should expect reduced visibility and slick spots through the morning commute.

According to the National Weather Service in Marquette, snow showers will persist through midmorning, adding 1 to 2 inches of new accumulation before tapering. Another system will redevelop late Thursday into Friday, keeping 3 to 5 inches possible across the lake-effect snow belts. Temperatures will hold steady near 25°F, but biting winds will make it feel much colder, dipping into the lower teens by evening.

By the weekend, Arctic air will tighten its grip on the Upper Peninsula. Saturday’s highs may only reach the mid-teens, and wind chills could fall below zero in exposed areas. The National Weather Service warns that travel on U.S. 41 and M-28 could become hazardous as blowing snow reduces visibility and refreezes melted snow into black ice by Friday night.

Meteorologists note this is part of a larger Great Lakes snow pattern expected to persist through December 17, with frequent bursts of light-to-moderate snow alternating with intense cold snaps.
