About 140 million people from New Mexico to New England were under winter storm warnings. The National Weather Service forecast warns of widespread heavy snowfall and a swath of destructive ice stretching from East Texas to North Carolina.

By Friday night, the storm's intensity was dropping freezing rain and sleet across parts of Texas, while snow and sleet were falling across Oklahoma. The weather service predicted that after dissipating in the south, the storm was expected to move northeastward, dropping about a foot (30 centimeters) of snow from Washington to New York and Boston.
