Our well-advertised blizzard delivered in spades Friday. Weather satellites can see the blizzard plume running more than 1,100 miles form Winnepeg to Ohio and beyond.

Highways in southern and western Minnesota were closed. Sustained 40 mph winds with 51 mph gusts whipped fluffy snow into a raging ground blizzard with visibility less than 1/4 mile to near zero at times.

And hurricane-force wind gusts over 70 mph along the North Shore in and around Grand Marais downed trees and created weather havoc.

Blizzard warnings continue until 6 a.m. Saturday across much of the eastern Dakotas, western and southern Minnesota, Iowa, Wisconsin and Michigan.
