DETROIT  (AP) – Utility crews in southern Michigan have been working to restore power to thousands of homes and businesses blacked out by thunderstorms that raked the region with wind up to 70 mph.

DTE Energy spokeswoman Lorie Kessler said Sunday that power had been restored to about half of the 125,000 customers that lost service in Saturday's storms.

Michigan's Consumers Energy also had customers affected. Spokesman Jay Jacobs said Sunday that electricity has been restored to all but 3,700.

Saturday's thunderstorms also battered parts of Kansas, Missouri and Oklahoma.

Officials said lightning killed a motorcyclist in Kansas.

Possible tornadoes caused scattered damage in Missouri, Kansas and Oklahoma. There were no immediate reports of severe injuries.
