What is the path and timeline of the winter storm affecting millions of Americans?

The winter storm is moving from Oklahoma City to Virginia Beach with warnings posted along this route. After dropping 4-5 inches in northeastern Oklahoma and Arkansas, the storm will track along I-40 tonight, reaching Nashville in the early morning hours. By afternoon, it will blast eastward toward Norfolk and Virginia Beach, with areas north and east of Raleigh experiencing sleet and freezing rain problems. The storm brings challenging travel conditions, particularly along I-95. While most of the storm's activity will be gone by Thursday, it will leave behind record cold temperatures affecting a wide area from Baton Rouge up to Omaha.
