A deadly blizzard paralyzed Buffalo, New York, on Christmas Day, trapping motorists in their cars, knocking out electricity to thousands of homes and raising the death toll from a severe winter storm system that has chilled much of the United States for days. At least 30 people have died in U.S. weather-related incidents, according to an NBC News tally, since a deep freeze gripped most of the nation, coupled with snow, ice and howling winds from a storm that roared out of the Great Lakes region late last week.
