KANSAS CITY, Mo. (AP) — Tens of thousands remain without power and dozens of schools have canceled classes after a deadly winter blast.

The storm hit the Midwest and mid-Atlantic region Friday, dumping more than a foot (30 centimeters) of snow across parts of Missouri. Authorities say at least three died in Missouri and two in Kansas on snow-covered roads.

Kansas City Power & Light says more than 45,000 customers still had no power Monday morning.

School closings also were widespread in the Kansas City and St. Louis area. The University of Missouri's flagship campus in Columbia says its campus will remain closed Monday, after Friday afternoon classes also were canceled.

In Columbia, snow also collapsed the roof of a dog training and event center. No one was inside the Columbia Canine Sports Center at the time.
