Michigan Upper Peninsula Braces for 8 Inches of Snow, Winter Storm Watch Issued

A winter storm is forecast to bring heavy, wet snow to Michigan’s Upper Peninsula beginning Tuesday evening, February 17th, and continuing through Wednesday, February 18th. The heaviest snowfall, potentially reaching 4-8 inches, is expected across the north-central Upper Peninsula and the Keweenaw Peninsula.

Storm System Details

The storm is linked to a powerful cyclone forming in the northern High Plains. According to the Weather Prediction Center, this system will bring heavy snow and blowing snow to northern Montana, as well as periods of snow and accumulating ice to the Upper Midwest and Great Lakes.

Timing and Accumulation

Snow is expected to begin after clouds increase Tuesday afternoon. The most intense snowfall and strongest winds are anticipated on Wednesday, with conditions gradually improving later that day. Forecasts indicate snowfall totals of 4-8 inches across much of the northern Upper Peninsula, 1-4 inches farther south, and potentially higher amounts in areas experiencing lake and terrain enhancement.

Potential for Ice

In addition to snow, a wintry mix is possible, particularly across the south-central and eastern Upper Peninsula. Forecast models suggest a 25–50% chance of light ice accumulation in these areas, with lower chances – under 20% – of more than one-tenth of an inch of ice. The heaviest icing potential is expected Tuesday night into early Wednesday before precipitation transitions to snow.

Expert Insight: The combination of heavy, wet snow and potential ice accumulation creates hazardous travel conditions. The proximity to Lake Superior could significantly increase snowfall totals in localized areas due to lake-effect enhancement.

Winter Storm Watch

A Winter Storm Watch is currently in effect for Marquette, Baraga, Northern Houghton, and Keweenaw counties. Forecasters note that the watch area could be expanded depending on the evolving storm track.
