After an analysis of the storm damage reports, weather.com meteorologists concluded the damage was caused by a derecho, a large cluster of thunderstorms that most commonly forms in late spring and summer and causes widespread destruction to trees, power lines and sometimes structures.
From the Spanish word for “straight,” these windstorms leave wide, long areas of straight-line wind damage. The winds can be as strong as 60 to 100 mph or higher in extreme cases. They’re usually produced by one or more curved lines of thunderstorms known as a bow echo or squall line.
