The derecho caused widespread wind damage throughout the Miami Valley with measured wind gusts over 80mph in a few locations.

Most notably, the storm caused the cancellation of the planned Freedom’s Call event at Wright-Patterson Air Force Base, which was an annual public event on the base grounds.


According to the National Weather Service, a derecho is a widespread and fast-moving storm that produces damaging straight-line winds that span over a hundred miles.
