2020 Midwest derecho

The 2020 Midwest derecho was an unusually destructive and extremely powerful progressive derecho that devastated much of the Midwestern United States, primarily eastern Nebraska, Iowa, Illinois, Wisconsin, and Indiana. It caused high winds and spawned an outbreak of weak tornadoes. Some areas reported torrential rain and large hail. The event came with no prior warning as weather forecast did not show the possibility of a derecho occurring until it was already in progress. Damage was moderate to severe across much of the affected area, as sustained wind speeds of 70 miles per hour (110 kilometers per hour; 31 meters per second) were prevalent. The greatest damage occurred in eastern Iowa, and northern Illinois, where multiple tornadoes touched down. The highest winds occurred in Iowa, measured at 126 mph (203 km/h; 56.3 m/s) and highest estimated from post-event damage surveys at 140 mph (225 km/h; 62.6 m/s). Millions across the Midwest were affected by wide-scale utility disruptions, residential and commercial property damage, and severe damage to corn and soybean crops. Cedar Rapids, Iowa, was the most severely damaged, suffering a near-complete blackout that lasted for weeks in some areas, widespread and severe property damage, and an estimated loss of at least half of the city's tree canopy. The derecho caused over $11 billion (2020 USD) in damages and spawned a years-long cleanup effort.
