Communities across the Plains awoke to damage and flooding Thursday after at least 50 tornadoes and baseball-sized hail were reported across a 500-mile stretch spanning four states.
Some of the worst damage was reported near Oklahoma City, where at least 12 people were injured after a twister tore through two trailer parks and downed power lines Wednesday.
The city also saw 7.1 inches of rain throughout the day — almost tripling the previous record for rainfall that was set in 1930. Weather Channel lead meteorologist Michael Palmer said this "unprecedented" downpour caused flash floods strong enough in some areas for cars to be partially submerged.
Oklahoma Gov. Mary Fallin was preparing to sign an emergency declaration for Oklahoma City and would be visiting some of the affected areas Thursday, her office said.
In Kansas, a tornado caused "significant damage" to homes and injured one person in the small community of Jewell, and another damaged buildings near Lincoln, according to the National Weather Service.
Between 10 and 15 homes were damaged in several communities in Nebraska near the Kansas line, The Associated Press reported.
