A powerful storm system barreled across the central U.S. Friday, killing at least 22 people and unleashing reports of at least 69 tornadoes recorded across at least eight states.
Fueled by a series of so-called supercells, the rotating thunderstorms that can spawn tornadoes, the system battered homes, downed trees and power lines and flipped cars and RV campers, with some landing in the Mississippi River.
