It has been a year. A year since most every Iowan learned what the term "derecho" meant and now knows not to ever want to experience one again. Derechos have hit or clipped the state a number of times in the past with the previous benchmark event happening in 1988. The 10 August 2020 far eclipsed that event and is currently considered the most costly severe thunderstorm event in US history totaling 11 billion dollars in damage. The featured lapse presents IEM generated composites of NWS RADAR along with NWS watches and warnings for the event in Iowa. You can find an excellent summary of the derecho on Wikipedia. Cedar Rapids was the hardest hit community with the tree damage cleanup recently ending 11 months after the derecho hit!
