One day after a violent storm system roared through parts of the nation's midsection, spawning tornadoes in several cities in Missouri and Arkansas, freezing temperatures Saturday threatened to compound the plight of victims left homeless due to the weather.

Temperatures in Sunset Hills, Missouri, dropped Saturday to 16 degrees Fahrenheit – with a wind chill of 7 degrees below zero, according to the National Weather Service.

Temperatures dipped into the 20s in parts of Mississippi, where the storm had knocked out power to nearly 20,000 homes.

Seven people died and dozens were hurt Friday in a storm system that stretched more than 1,000 miles from the Northern Plains down to the mid-Mississippi Valley.

On Saturday, Missouri Gov. Jay Nixon toured a neighborhood in Sunset Hills, a St. Louis suburb. "Bottom line [is] significant property loss," he said.

The tornado that hit Sunset Hills will be rated an EF3, the National Weather Service said.

An EF3 twister has winds between 136 – 165 mph, according to the weather service.

A family of seven lost their home in north St. Louis, CNN affiliate KMOV reported. William Gibbs told KMOV that his daughter told him that there would be a tornado. "I took it for granted," Gibbs told KMOV. "I'm thanking God that we're all safe but, I don't know where we go from here," he said.

Latasha Stuhlman told CNN affiliate KMOV that her home has been condemned after the storm hit her neighborhood. The Stuhlmans will sleep in a hotel with other families.

“It’s bad. Real bad," Stuhlman told KMOV. "The people that said they went in [to the property] said my whole bedroom’s gone.”

The St. Louis-area Red Cross said in a news release that it had provided assistance to about 60 people Friday and expected that number to grow following a damage assessment.
