The Texas and Oklahoma Panhandles are bracing for what National Weather Service forecasters are calling a "historic blizzard."
Between 6 to 15 inches of snow are in the forecast for the region, which includes Amarillo and Lubbock. High winds will drive wind chills as low as 10 below zero and cause low visibility due to blowing and drifting snow.
The blizzard warning for the region takes effect at 6 p.m. Saturday and runs through noon Monday.
Other parts of Texas and Oklahoma, including El Paso, are under winter storm warnings, while North Texas, central Oklahoma and central Kansas are under a winter storm watch.
Widespread rain has prompted flash flood watches in eastern Texas, eastern Oklahoma, most of Arkansas, central and southern Missouri and Illinois and central Indiana.
