Snow threatens holiday travel in Great Lakes as freeze watches affect South

Snow is expected to disrupt travel in the Great Lakes region this holiday weekend. A significant lake effect snow event could bring over 3 feet of snow in some areas, with blinding snowfall rates of 3 to 4 inches per hour. Winter alerts are in effect for 6 million people from northern Minnesota to upstate New York. Areas near Lake Ontario may see up to 60 inches of snow, impacting travel on major highways like Interstate 90 and Interstate 81. In the South, about 9 million people are under freeze watches from Texas to the Carolinas. Cold Arctic air is expected to move south, bringing even colder temperatures in the coming days.
