Most of the country will wake up to rain, snow, ice or any combination of them on Thanksgiving morning, according to forecasters.
Ice could cause travel problems across the central United States from Kansas City, Missouri, to Texas. Major flooding is predicted for large parts of Texas, Oklahoma and Arkansas through Friday.
Winter storm warnings are in effect for parts of Nebraska, Oklahoma, Iowa, Nevada, Colorado, Idaho, Wyoming and Montana, while Rock Springs, Wyoming, was under a blizzard warning.
Wyoming — especially near Interstate 80 across the state — is "going to get hit very hard," said Danielle Banks, a meteorologist for The Weather Channel, while parts of northern New Mexico could get as much as 18 inches of snow.
