With millions of people preparing to travel for the Thanksgiving holiday, two strong storm systems are forecast to bring snow, wind and rain across a large swath of the United States this week.

A powerful winter storm is set to blast portions of the U.S. with accumulating snow, cold temperatures, strong winds and rain just as millions of people across the country prepare to travel early for Thanksgiving.

Multiple weather fronts will push rain and snow into the Midwest, Southeast, Mid-Atlantic and Northeast ahead of Thanksgiving week and some of the year's busiest travel days.
