Forecasts of a treacherous mix of snow and ice have shifted more than 20 million people from Texas to the Carolinas into the winter severe weather warning.

With North Carolina still reeling from a winter storm this past weekend, Gov. Roy Cooper has declared a state of emergency.

At 3 (15: 30), the national weather service’s latest forecast called for a wintry mix of rain, freezing rain and sleet in southern southern Southern Central Texas this evening, with temperatures in the area dropping into the 20s and 30s.

Coastal North Carolina is expected to have up to a half inch of ice, while eastern North Carolina could receive four to six inches of snow.

TxDOT District Engineer Gina Gallegos says crews will work the entire night to pave key roads and highways and have crews on standby to tackle emergency situations.

The storm is expected to spread to the sea through Saturday.
