Michigan – Light fog and 28-degree air greet early drivers in Marquette, but the quiet start will not last. A Winter Storm Watch now signals a high-impact February storm arriving Tuesday night, threatening heavy snow and difficult travel by Wednesday morning.
According to the National Weather Service in Marquette, the watch runs from Tuesday evening through Wednesday evening for Marquette, Baraga, Keweenaw, and northern Houghton counties. Forecasters expect mixed precipitation to change to heavy snow. Total snow accumulations could reach 4 to 8 inches, with higher amounts possible across the Keweenaw Peninsula. Wind gusts may peak near 45 mph along Lake Superior.
Today stays relatively calm. A few snow showers are possible, with highs near 42°F. Temperatures fall to 22°F tonight under partial clearing, allowing roads to refreeze in spots.
Tuesday brings clouds and highs near 34°F before snow develops after sunset. Conditions deteriorate quickly overnight as snowfall intensity increases and winds strengthen.
Wednesday, February 18, looks impactful. Heavy snow and blowing snow may reduce visibility below one mile at times. Travel along US-41 and M-28 could become hazardous during both the morning and evening commutes. Wet snow combined with gusty winds may down tree limbs and cause isolated power outages.
Colder air lingers late week with highs in the 30s and additional snow showers possible.
Looking ahead to President’s Day Week, the 6- to 10-day outlook suggests temperatures gradually moderate. After this Winter Weather surge, a milder pattern may return, but February in the Upper Peninsula rarely stays quiet for long.
