Freezing rain is coating roads in northern Minnesota with a thick layer of ice.
The National Weather Service issued an ice storm warning for parts of northern Minnesota, including Cass, Beltrami and Koochiching counties.
State Patrol Sgt. Jesse Grabow said late Friday that Interstate 94 was shut down from Fergus Falls to Alexandria due to extremely icy conditions.
Grabow said troopers in northwest and west-central Minnesota have responded to 18 crashes, four of which were rollovers. Another 31 vehicles were spun out or off the road.
Slick travel conditions caused some school districts to cancel or delay classes Friday.
The Duluth News Tribune says Duluth, Ely, Hibbing and Chisholm schools were among those closed.
MnDOT was advising no travel on Highways 113 and 108 near Waubun and Pelican Rapids because of icy conditions.
National Weather Service meteorologist Todd Krause says temperatures are dropping rapidly in western Minnesota as the cold front moves in.
Freezing rain is expected to end later Friday with snow developing. Forecasters expect 3 to 7 inches of snow for northern St. Louis, northern Itasca and Koochiching counties.
