Winter Storm Ravages the United States

Heavy snowfall barreled across the United States, Tuesday, December 3, causing flight delays and blocking highways.

Videos shot during a flight from Boston, Massachusetts to Los Angeles, California show the long-lasting snowfall from inside a plane.

The storm that started on the West Coast ahead of Thanksgiving, the busiest U.S. travel holiday, slowly rolled across the entire country, drenching some areas with rain, blanketing others with snow and blasting still others with winds. Three tornadoes were reported northwest of Phoenix.
