The first big snowfall of the season blanketed parts of New York, Pennsylvania and Michigan during the hectic U.S. holiday travel and shopping weekend, with numbing cold and heavy snow forecast to persist through the early part of the week and cause hazards in the Great Lakes, Plains and Midwest regions.

The snow storm led to an emergency declaration in parts of New York and a disaster declaration in Pennsylvania, with officials warning of dangerous conditions for Thanksgiving travelers returning home.
