BOSTON (AP) -- Street and highway crews were at work trying to clear roads across the Great Lakes states into New England on Sunday as a storm blamed for three deaths spread a hazardous mix of snow, sleet and freezing rain.

The National Weather Service posted winter storm warnings from Michigan and Indiana all the way to Maine. Nearly a foot of snow had already fallen on the Chicago area and meteorologists said accumulations of up to 14 inches were possible in parts of Michigan by late Sunday.
Dozens of traffic accidents, most of them minor, had been blamed on slippery roads and whiteout conditions in Massachusetts. Michigan police reported minor road accidents across the state and churches in Michigan and upstate New York canceled services because of the weather.
Illinois Department of Transportation spokesman Mike Claffey said 1,000 trucks were out clearing snow Sunday. The city of Chicago had close to 400 trucks and modified snowplows working through the night.
The storm canceled hundreds of flights at airports in Chicago, where Midway Airport measured 10 inches of snow by Sunday morning. No delays were reported at Boston’s Logan Airport, but officials urged travelers to check with their airlines. Boston expected 5 to 8 inches of snow, with heavier amounts likely in northern New England.
In Buffalo, the weather was no deterrent to NFL fans who rose early for a bus trip to Cleveland to see the Bills play the Browns.
“Rain, snow, sleet, whatever, we’ll be there,” Brian Kras said, boarding a chartered bus at 5:30 a.m.
Numerous flights at Buffalo Niagara International Airport were canceled Sunday morning as 5 to 7 inches of snow was expected.
An estimated 103,000 customers were blacked out Sunday morning in parts of Pennsylvania, the utilities PPL and MetEd reported.
The storm came less than a week after an ice storm blamed for at least 38 deaths, mostly in traffic accidents, in the middle of the country. Thousands of homes and business still had no electricity in parts of Oklahoma, Kansas and Missouri.
More than 200 flights were canceled Saturday at Chicago’s O’Hare International Airport, one of the nation’s busiest, and all other flights were delayed an hour, said Chicago Department of Aviation spokesman Gregg Cunningham. Road travel was tricky in the metropolitan area.
Slippery roads were blamed for two traffic deaths in Michigan and one in Wisconsin.
Concern about the approaching storm led the University of Connecticut to cancel Sunday’s winter commencement ceremony. About 850 undergraduates had expected to receive diplomas Sunday, but school spokesman Richard Veilleux said officials were concerned about the safety of the students and their families and other guests on slippery roads.
