powerful winter storm lay a snow blanket from the South to the Northeast on Sunday, turning roads slick, stranding thousands of airline, train and bus passengers and putting a chill in retailers' day-after-Christmas sales.
Up to 20 inches of snow were expected in some areas, including Philadelphia, where the Eagles-Vikings NFL game was canceled, and Boston, where an aquarium had to protect - of all things - penguin ice sculptures from the elements.
Snow started falling around New York City late Sunday morning, by which time nearly 1,000 flights out of the region's three major airports had already been canceled in anticipation of the storm. More cancellations were expected.
