A powerful storm system roared across the Midwest and South Friday night, unleashing a series of tornadoes that carved paths of destruction and left at least three dead in Missouri.

The threat of tornadoes moved east into the Mississippi Valley and Deep South on Saturday, a day after a massive storm system moving across the country unleashed winds that damaged buildings, whipped up deadly dust storms and fanned more than 100 wildfires.

The death toll increased overnight from a powerful storm system that caused havoc in the middle of the country, triggering wind-driven wildfires and blinding dust storms in the Plains before spawning multiple destructive tornadoes in states like Missouri and Mississippi.
