Earlier Friday evening, a tornado was reported in Fair Play, Missouri. Melissa Chance was at work when she got a warning from a colleague who is a first responder: She needed to alert her family that a tornado was headed toward their home.

Her husband and 5-year-old son barely made it from their mobile home to a nearby storm shelter before the twister hit. They hunkered down with a neighbor as the storm surged around them.

"When they were in the shelter with the neighbor, they heard a lot of crashing and what would be our homes and our vehicles being smashed together," Chance told The Weather Channel.

When they emerged, their homes were destroyed.

"We have to start over. You can’t give up. I’m in shock. I’m absolutely devastated. I’m in shock," Chance said, choking up at the thought. "I built years and years of memories with my family in this home."

Liz Burns, another Fair Play resident, was standing at her front door when she heard tornado sirens go off. She pulled out her phone and began shooting video as the storm passed her home.

"It took us a second to see it but it was right over the top of the barn, and it followed our fence line. Scary as hell," Burns told weather.com in a phone interview Friday night. "I almost had a panic and all I’m thinking is 'Oh s---, what if it turns?' Because we don’t have a shelter here – we only have a closet."

Her two young children and their dog were also in the home. The storm passed and their property was left unscathed.

The severe weather is being produced a system that is bringing snow, sleet, ice and freezing rain to other parts of the country. That system has been named Winter Storm Isaiah by The Weather Channel.

"The same strong upper-level storm that's producing winter weather in the Midwest is generating severe weather in the South," Weather Underground weather and climate blogger Bob Henson said. "The winter weather and severe weather are both being driven by upper-level winds and atmospheric moisture that are close to record levels for January."
