Survivors of deadly tornadoes share stories of making it through the extreme weather: "We wouldn't be alive"

A massive storm system that brought high winds, rain, tornadoes and wildfires killed at least 40 people in the Midwest and South over the weekend. Some survived the extreme weather by leaving just in the nick of time or riding out the storm.

Aaleigha Contreras, 9, convinced her family to evacuate their home in Poplar Bluff, Missouri, before a tornado barreled through Friday night.

Aaleigha's mom, Kelsey Webb, told CBS News correspondent Jason Allen, "I was like, 'We've stayed here through several tornadoes, it'll be fine,' and then she's like, 'No, Mom, we need to leave.'"
