Another round of dangerous severe weather is expected to slam the Plains on Monday, after tornadoes that ripped through the nation's midsection on Sunday killed one and left more than 20 injured.
A tornado in Shawnee, Okla., severely damaged a mobile home park and killed a 79-year-old man whose body was found out in an open area of the neighborhood.
"You can see where there's absolutely nothing, then there are places where you have mobile home frames on top of each other, debris piled up," Pottawatomie County Sheriff Mike Booth said after surviving damage in the Steelman Estates Mobile Home Park. "It looks like there's been heavy equipment in there on a demolition tour.
"It's pretty bad. It's pretty much wiped out," he said.
The storms in Oklahoma that ripped off roofs and tossed big trucks like toys were part of a severe weather outbreak that stretched from Texas to Minnesota. Twisters were also reported Sunday in Iowa and Kansas.
Across Oklahoma, 21 people were injured, not including those who suffered bumps and bruises and chose not to visit a hospital, said Keli Cain, a spokeswoman for the Oklahoma Department of Emergency Management. Booth said six at Steelman Estates were hurt.
Gov. Mary Fallin declared an emergency for 16 Oklahoma counties.
Interstate 40 was closed by the Oklahoma Highway Patrol after winds overturned semi-tractor trailer trucks and other vehicles, Newsok.com reported.
KFOR-TV showed footage of homes damaged and cars and trucks flipped from highways near Shawnee. Other video showed flashes from electrical transformers blowing out as they were hit by high winds or debris from the tornado near Edmond.
A tornado touched down in Golden City, Mo., early Monday morning and tore through two counties, Barton County Emergency Management Director Tom Ryan told CNN. The number of injuries and extent of damage were not immediately clear.
Christopher Apgar and John Spain captured highly destructive tornadoes on camera near Shawnee, Oklahoma. They say one was nearly half a mile to a mile wide.
Sedgwick County, Kan., emergency management director Randy Duncan says officials are grateful for few reports of damage from a tornado that touched down near Wichita Mid-Continent Airport. He told CNN the area emerged "relatively unscathed.''
Forecasters had been warning for days that severe storms were likely across the region.
"I knew it was coming," said Randy Grau, who huddled with his wife and two young boys in their Edmond's home when the tornado hit. He said he peered out his window as the weather worsened and believed he saw a flock of birds heading down the street. "Then I realized it was swirling debris.''
In Iowa, a tornado touched down on Sunday about 30 miles west of Des Moines near the town of Earlham, the Des Moines Register reported.
Meteorologist Kurt Kotenberg said a large low-pressure system is parking itself over the middle of the country and "really isn't going to move much over the course of the next few days. ... It's basically going to keep pulling up that nice Gulf (of Mexico) moisture that keeps fueling everything."
Overall, Iowa has a roughly 70% chance of severe thunderstorms from late Sunday afternoon through midnight, with more storms likely on Monday and Tuesday, Kotenberg said. The weather service's "hazardous weather outlook" warns of the potential for "all modes of severe weather possible," including golf-ball sized hail and winds in excess of 60 mph.
The threat of twisters comes less than a week after tornadoes left six dead, dozens injured and hundreds of homes destroyed in Texas and just shy of the two-year anniversary of the Joplin, Mo., twister.
