A powerful storm system over the southern Plains has begun to produce severe thunderstorms, flooding rain and blizzard conditions over the region.
The primary threat through the first half of the night will be severe thunderstorms in eastern portions of Texas and Oklahoma.
According to AccuWeather Senior Meteorologist Frank Strait, thunderstorms will continue past midnight and will bring the threat of damaging wind, hail and a few isolated tornadoes.
Meanwhile, blizzard conditions will begin to unfold over eastern New Mexico and the Texas Panhandle.
"The combination of strong winds and heavy snow will create blizzard conditions from Roswell, New Mexico, to Lubbock and Amarillo, Texas," AccuWeather Meteorologist Brett Rathbun said.
