A house is left damaged after an aparent tornado hit on Saturday, April 14, in Thurman, Iowa. The National Weather Service received more than 88 reports by late Saturday of possible tornado touchdowns in Oklahoma, Kansas, Nebraska and Iowa, said Pat Slattery, a spokesman for the service's Central Region in Kansas City, Missouri. 
The streets are littered with trees and debris after the aparent tornado struck Thurman. Officials evacuated the entire population of the town -- roughly 300 people. The storm destroyed three out of every four homes in Thurman. 
By early Sunday morning, many Thurman residents who took up temporary shelter at a high school in nearby Tabor were again in the path of a storm that spawned suspected tornadoes in neighboring Kansas.

Woodward, Oklahoma (CNN) -- It came in the middle of the night while a city slept, taking aim at the Hidden Valley Mobile Home Park in Woodward, Oklahoma, where Frank Hobbie and his two young daughters lived.
Nobody knows if Hobbie and the girls, ages 5 and 7, had any idea what hit them.
Their bodies were among five found in the early morning hours Sunday after the city was struck by a twister -- one of more than 130 believed to have been spawned by a furious storm system that wreaked havoc across large swaths of 10 states in the Midwest and Plains over the weekend.
While authorities from Texas to Minnesota on Monday tally the storm's toll -- from destroyed businesses to flattened homes, from downed power lines to overturned tractor-trailers -- people in Woodward are making plans to bury their dead.
The only known casualties of the storm system occurred in the northern Oklahoma city of about 12,000, about 85 miles west of Enid. At least 29 people were injured, officials said.
Hobbie was confirmed dead along with two girls, said Amy Elliot of the Oklahoma Medical Examiner's Office. The identities of the girls were not immediately released.
Elliot identified the other dead as Derrin Juul and a 10-year-old girl, who is presumed to be Juul's daughter. The two were killed when the tornado's powerful winds rolled the car they were in several times, said Woodward Mayor Roscoe Hill.
By early Monday morning, the National Weather Service lifted the last of widespread tornado watches in Minnesota, Wisconsin, Arkansas, Iowa and Illinois after threats of another furious outbreak of tornadoes never materialized. Strong thunderstorms remained a possibility during the early morning hours, the service said.
The weather service's Storm Prediction Center received 10 reports of tornadoes on Sunday -- the last a reported touchdown in McLeod County in Minnesota -- and 122 reports of tornadoes on Saturday.
Officials credited working early warning systems elsewhere in the region with preventing more fatalities.
Advisories from the system were issued two days in advance, rather than just a matter of hours, and were "remarkably accurate," said Kansas Gov. Sam Brownback. "People took it very seriously."
But in Woodward, Oklahoma, where 89 homes and 13 businesses were destroyed, the storm took out the transmitter for the tornado warning siren system. "We lost our manual override" when the electricity was knocked out, City Manager Alan Riffel said.
Given that and timing of the tornado -- after midnight, and after other severe weather had barreled through -- Oklahoma Gov. Mary Fallin said the human cost could have been even worse.
"It's remarkable that we didn't have more loss of life in Woodward," she told reporters late Sunday afternoon.
Fallin has declared a state of disaster emergency in 12 counties in order to help expedite resources.
In southwest Iowa, residents of Thurman began returning Sunday to dig through debris after a tornado struck Saturday.
"About 75% of the homes are damaged or destroyed," said Mike Crecelius, Fremont County's emergency management director.
Four truckers whose rigs were blown off Interstate 29, by the same tornado that struck Thurman, were the only ones hospitalized with storm-related injuries, the weather service said. The agency reported the twister had winds between 111 and 135 mph as it caused a half-mile long damage path over 10 miles.
Earlier, a confirmed tornado struck a hospital in Creston, Iowa, blowing out windows and damaging the roof, said John Benson of the Iowa Homeland Security and Emergency Management agency. There were no major injuries reported, and patients were relocated to other area hospitals.
One of the biggest cities hit over the weekend was Wichita, Kansas, where resident Katie Sykes said torrential rains produced a "river in my front yard" and the prospect of a tornado had her shuddering in fear.
"When I was little we prepared for storms, hearing the sirens and then going to the basement. And going through this experience I felt like a little kid, young and scared," Sykes said.
A tornado churned across the southern part of the city, home to a number of aircraft-related manufacturers. The tornado struck Boeing and Sprit AeroSystems, officials said.
A few hundred employees were working at a Spirit Aero Systems plant, producing fuselages and other equipment for Boeing aircraft, said company spokesman Ken Evans, when a twister came through and caused the roof to collapse. No one was injured, and workers have been told not to come in until Wednesday as the damage is assessed.
CNN's Rob Marciano reported from Oklahoma and Maria P. White from Atlanta.
