On August 4, a derecho traveled 300 miles from east Iowa to Ohio, disrupting the Lollapallooza festival in Chicago.[1] There were over 150 reports of wind damage from this storm, with five reports of hurricane force winds (more than 74 mph) and a tornado. The derecho narrowly missed the same west-central Ohio area which was struck by three derechos within four weeks from the end of June to the end of July.[2]
