A severe winter storm buried Minnesota and surrounding areas in 15 inches of snow that froze overnight and paralyzed transportation throughout the weekend.
The storm's combination of snowfall, frigid temperatures, and wind caused more than 600 car accidents, another 1,300 spinouts off the road, and more than 150 canceled flights, according to the Minnesota State Patrol and the Minneapolis-St. Paul Airport.
The conditions were bad enough that state highways in west and southwestern Minnesota were closed Sunday afternoon. The state later took all snowplows off the roads.
St. Paul and Minneapolis were among the worst hit, according to the National Weather Service. The twin cities saw 10 to 15 inches of snow and single-digit temperatures. The sheer volume of snow made the weekend's storm once in a generation—the 10.5 inches of snow that fell at the area's airport in 24 hours has only happened 20 times in the past 128 years, according to the NWS.
The deepest snow was 17 inches, considerably more than the area's heaviest snowfall last year, which was 4.2 inches.
Parts of Wisconsin, along with North and South Dakota also reported snows of up to 9 inches. The storm, which the Weather Channel dubbed Caesar, is moving slowly toward the northeast, where it will likely hit Michigan and move into Canada in the coming days, according to the National Weather Service.
