Winter storm watches continue for parts of New York, Michigan, Pennsylvania and Ohio on Wednesday, where lake-effect snow is expected to wallop parts of the Great Lakes region, while a good portion of the continental United States is experiencing bitter-cold temperatures.

Cleanup work is continuing around parts of the Great Lakes region socked by lake-effect snowstorms that dropped several feet of snow over the weekend.

The Great Lakes experienced a surge of activity as arctic air passed over record-warm waters, generating prolific snowfall.
