Maximum wind speeds were estimated to be up to 125 mph.

A major tornado outbreak impacted the Midwest and Ohio Valley on November 17th. A powerful low pressure system across the plains states steered warmth and moisture northward for nearly two days, with dew points rising into the mid 60's. This coupled with temperatures around 70 resulted in unseasonably strong instability for thunderstorms to develop. High wind shear and a cold front sweeping eastward made up the remaining ingredients of an environment favorable for supercells capable of long-lived significant tornadoes. Within the WFO LOT county warning area, ten tornadoes were confirmed, including three EF-2 tornadoes. As the event evolved, the system became linear with numerous reports of straight line wind damage. Behind the thunderstorms, a wake low developed with wind gusts to around 60 mph.
