There were reports of widespread damage and multiple injuries.
At least nine tornadoes were reported in Kansas and Oklahoma on Sunday night as a massive winter storm moves east across the U.S.
One tornado destroyed a home, toppled trees and knocked over power lines in Liberal, Kansas, near the state line with Oklahoma, according to local authorities.
At least 12 people were injured due to the severe weather in Oklahoma's third-largest city, Norman, located about 20 miles south of the state's capital. None of the injuries were critical and there were no reported fatalities, according to the city.
Drones are helping assess damage on Monday, Norman Police Chief Kevin Foster said.
Some roads have been shut down and two Norman elementary schools are closed, Foster said.
Wind gusts over 70 mph and hail measuring 1 inch in diameter were reported in Oklahoma City. Meanwhile, gusts of 114 mph were recorded in Memphis, Texas, near the state line with Oklahoma, according to the National Weather Service.

More than 40,000 customers remain without power in California.
After sweeping across the Great Plains on Sunday night, the fast-moving system is forecast to hit the Midwest on Monday afternoon and then the Northeast by Monday evening.
Severe thunderstorms are possible in Illinois, Indiana, Ohio and northern Kentucky. One tornado was already confirmed in Illinois Monday morning and more are possible in Indiana and Illinois in the afternoon.
In Minnesota, Wisconsin and Michigan, a mixture of ice and snow is in the forecast.
Over 140,000 customers are without power in Michigan in the wake of a major ice storm that struck last week.
In the Northeast, the snow will begin Monday night, with snowfall rates possibly reaching 1 to 2 inches per hour in New Jersey, New York City and Connecticut.
