MetCon also provided the following commentary regarding the Midwest Derecho:
A few fast facts about Derechos:
Derechos are most common in the late spring and summer (May through August), with more than 75% occurring between April and August.
While derecho winds typically are less than 100 mph, gusts as high as 130 mph have been recorded (May 1998) — equivalent to those with strong EF2 tornadoes.
The winds associated with Derechos are not constant and may vary considerably along the derecho path, the swaths of stronger winds within the general path of a derecho are produced by events known as downbursts, these downbursts often occur in irregularly-arranged clusters of thunderstorms.
