CHICAGO (Reuters) - A late-season winter storm slammed into the Ohio Valley on Saturday, forcing flight delays and cancellations at airports before heading out toward the eastern Great Lakes and the Northeast.
Canada also was being hit with a winter blast that snarled air traffic and wreaked havoc on the roads.
Snow totals from Ohio to western New York could exceed 15 to 20 inches by Sunday, the National Weather Service said. Ahead of the snow, freezing rain, ice and sleet fell from eastern Kentucky into New York state.
Ice and heavy, blowing snow closed Cleveland Hopkins International Airport around 11:45 a.m. EST, the Federal Aviation Administration said. It was not expected to reopen until Sunday morning.
The storm extends a brutal season for much of the central United States, where people have faced some of the heaviest snowfall and mix of wintry conditions in years.
Chicago was hit on Saturday by lake-effect snows whipped up over Lake Michigan, and was shivering in the coldest late-season temperatures in five years.

A storm that hit eastern and central Canada was expected to leave parts of the country buried under more than 16 inches of snow over the weekend.

Weather advisories were in effect across Atlantic Canada, from rain and wind warnings in Nova Scotia to snow and freezing-rain warnings in New Brunswick and Newfoundland and Labrador.
The storm has resulted in so many car crashes that police in Ontario were no longer attending crash sites. Instead, they were asking those involved in a collision to get a tow and report to a designated center, local media said.
