MINNEAPOLIS -- A winter storm that blew through the upper Midwest over the long Presidents Day weekend coated roads with ice and snow and led airlines to cancel hundreds of flights.
Residents of Michigan, Minnesota and Wisconsin who didn't get the Monday holiday off faced what was expected to be a dismal commute. Officials were urging people to stay off the roads if possible, rather than risk driving on icy roads or through wind-driven snow.
Hundreds of flights were canceled at Minneapolis-St. Paul International Airport and at Detroit's Metro Wayne County airport as the storm started moving through Sunday.
The National Weather Service said up to 13 inches had fallen in the Twin Cities by Sunday night, and light snow and freezing drizzle was expected to continue into Monday morning. The storm brought with it winds of 15 to 30 mph.
Minnesota Department of Transportation spokesman Kevin Gutknect noted that at least Monday's light holiday traffic would make more room for snow plows. Blowing snow was expected to make clearing the roads difficult.
"If people don't need to travel, they shouldn't," Gutknect said. "It's really hard for people to see."
The University of Minnesota closed its Twin Cities campus until noon Monday, and the Minnesota Historical Society postponed its History Matters Day at the state Capitol in St. Paul.
Several cities in the southern half of the state, including St. Paul, declared snow emergencies, which typically trigger parking restrictions that make it easier to clear the streets. Minneapolis public works officials said they would wait until the snowfall ended before decided whether to declare a snow emergency.
The Wisconsin Department of Transportation said driving conditions were hazardous as the storm brought a mix of ice, snow and high winds to the southern part of the state and heavier snow further north. The agency said numerous slide-offs and crashes had been reported on interstates by Sunday night. The National Weather Service said snow accumulations could reach more than a foot in central Wisconsin.
In Michigan, state police cautioned that mix of snow and freezing rain was expected through midday Monday in the southwestern part of the state. Up to a foot of snow was forecast in some areas. Mecosta County Sheriff's Sgt. J. Koepke said southbound U.S. 131 was closed for several hours Sunday after 50 to 60 vehicles crashed near Big Rapids.
