The Great Lakes region on Saturday began digging out from the season's first major snowstorm as the Midwest and Plains shivered under an arctic blast forecast to spread over the eastern third of the country.

A blast of Arctic air taking over much of the U.S. is bringing powerful lake-effect snow to several states and shivering temperatures to parts of the South.

Areas of Michigan, northern New York, Ohio and Pennsylvania could receive several feet of snow over the weekend. The storm already brought deep snow to portions of Michigan’s Upper Peninsula.
