Detroit - Wind gusting more than 60 mph knocked out power to about 370,000 Michigan homes and businesses on Sunday as temperatures dipped back into the 20s and 30s.
Meanwhile, flood warnings were posted throughout the Midwest as temperatures rose after a week of heavy snowfall. Forecasters said flooding was possible in areas of Wisconsin, Ohio, Iowa, Michigan and Indiana.
In Michigan, high wind knocked down tree limbs and power lines. Parts of the state also got about 4 inches of snow.
"We've had an intensifying storm system track northeast through the state," said Mark Sekelsky, a meteorologist with the National Weather Service in Grand Rapids. "As that storm intensified, it brought the winds."
