It was August 10 and 11, 2020, when the Iowa sky turned green and all hell broke loose. A devastating weather event called a Derecho blazed through Iowa, Nebraska, Illinois, Wisconsin, and Indiana.

Described as a hurricane over Iowa the storm caused an estimated $11 billion in damages and spawned a years-long cleanup effort.

 

 

A derecho is described as a “widespread, long-lived, straight-line wind storm that is associated with a fast-moving group of severe thunderstorms known as a mesoscale convective system. Derechos can cause hurricane-force winds, tornadoes, heavy rains, and flash floods.”
