DAMAGING DERECHO POSSIBLE THURSDAY - If you have friends or family anywhere from the Ohio Valley to New England, share this post or give them a call. An outbreak of severe storms capable of extremely damaging winds is likely Thursday. In case you are wondering, a derecho is a long-lived, widespread, damaging wind event associated with a fast-moving band of thunderstorms. Notice the pinkish, purple area with the black hatches over it. In this area there is a 45% chance of damaging winds/large hail within 25 miles of a point. Some of the winds could exceed 75 mph. A Derecho produces very few tornadoes. Straight-line winds are the primary concern.
