A “Derecho” Thunderstorm Complex Stormed Across Central Iowa Monday
A thunderstorm complex known as a “Derecho” moved across central Iowa during the day Monday. A Derecho is a thunderstorm complex with intense winds that is fast moving and travels a great distance. Thunderstorm wind gusts within a derecho can reach 100 MPH. The thunderstorm complex often looks like a bow on radar images. Below is the track of the derecho that made it’s way across South Dakota, Iowa, Illinois, Indiana and Ohio yesterday from the Storm Prediction Center.
A derecho only occurs in the United States 1 to 3 times per year and are most common in June, July and August.
Below are some pictures of the derecho thunderstorm complex that made it across Iowa yesterday.
@NWSDesMoines this is behind our house in Huxley. Straight line wind or tornado?? Lost most of our tree in the yard. Part of tree did punch a hole in wall of house and hole in roof pic.twitter.com/t5u3u2pjXv

Video from inside the beast. More than 20 minutes of 70-100mph gusts. Craziest experience of my life. This was near Van Horne, IA. #IAwx #derecho #derecho2020 @NWSQuadCities @NWSDesMoineshttps://t.co/azppET9kAk
