DULUTH - A late winter storm in parts of Minnesota, Wisconsin and Michigan's Upper Peninsula has brought heavy rain and snow and high wind.

The National Weather Service posted a winter storm warning into Thursday for parts of northeastern Minnesota, northwestern Wisconsin and the U.P. Forecasters expected as much as a foot of snow to accumulate Wednesday through Thursday in some areas.

Wisconsin Emergency Management said that heavy rains and high wind Tuesday night into Wednesday caused damage across the state, with downed trees and power lines blocking roads in southern Wisconsin and northern Wisconsin getting hit with snow. A tree fell on a school bus in Milwaukee, but nobody was hurt.

Winds topping 50 mph had prompted officials Wednesday to close the Mackinac Bridge connecting Michigan's Upper and Lower peninsulas except to passenger cars, passenger vans and empty pickups.
