Thursday's storm also spawned two tornadoes, the National Weather Service reported. Both touched down in Macomb County.
Electricity had not been restored to 64,000 homes and businesses in Macomb and Oakland counties Friday morning, a spokesman for DTE Energy told the Detroit Free Press. Most were expected to have power back by the end of the day.
While the tornadoes did considerable damage, especially to roofs, straight-line winds measured at up to 70 mph contributed, the NWS said.
Scattered thunderstorms were in the forecast for Saturday. But Karen Clark, an NWS meteorologist, said there was a good chance they would avoid the Dream Cruise, a large parade of classic cars scheduled Saturday afternoon on Woodward Avenue.
