Powerful storms with widespread wind gusts and reported tornadoes swept across Oklahoma and Kansas, leaving more than a dozen people injured.

 About 20 miles south of Oklahoma City, the Norman Police Department responded last night to storm damage on the south and eastern sides of Norman. Officials say there were 12 confirmed weather-related injuries, but none were considered critical.

 Crews were canvasing the damaged area looking for others who might be injured. Possible tornadoes and widespread wind gusts up to 90 mph were reported in Oklahoma, with downed trees and power lines, road closures and damage to homes around Norman and Shawnee.

 A tornado touched down Sunday near Liberal, Kansas, the National Weather Service said, and more than a dozen homes were reported damaged, according to KSNW-TV. One person had minor injuries.

 The Storm Prediction Center said that the severe weather threat remained Monday as thunderstorms were expected to produce damaging gusts across the Ohio Valley.

 In Coffeyville, the storms did not produce much rain, with only 16 hundredths of an inch recorded at KGGF. Wind gusts were recorded as high as 58 miles per hour.
