Meteorologists confirmed it was a “derecho” - a widespread and long-lived straight line windstorm, from a group of fast-moving severe thunderstorms. To be categorized as a such, the swath of wind damage must extend for more than 250 miles, include wind gusts of at least 58 mph for most of its length and include several wind gusts of at least 75 mph.
