Marquette, Michigan – Slick roads could develop across central Upper Michigan before sunrise Friday as a burst of wintry precipitation moves through overnight.
According to the National Weather Service in Marquette, light snow and a mix of rain and freezing rain will spread across the region late tonight into the pre-dawn hours. The greatest concern centers on light ice accumulation, which may create hazardous travel conditions on untreated roads through the Friday morning commute.
The Keweenaw Peninsula and far eastern Upper Peninsula, including Houghton and Sault Ste. Marie, are expected to see mainly snow, while areas around Marquette, Escanaba, and Iron Mountain could experience a mix of precipitation types. Key routes such as US-41 and M-28 may become slick, especially on bridges and elevated surfaces.
While snowfall totals remain light, even a thin glaze of ice could lead to reduced traction and slower travel speeds. Some patchy freezing drizzle may linger into mid-morning Friday, extending the risk.
Drivers should allow extra time, reduce speeds, and use caution on untreated roads. Additional advisories may be issued if ice coverage becomes more widespread into the morning hours.
