EF1 tornado in Kankakee County, Illinois

The tornado formed along the Kankakee-Will County Line just west of N 17480 E Road. Large branches from hardwood trees were broken off while an older softwood tree was snapped at the base. A hardwood tree was also snapped in half. The tornado had estimated winds to around 100 mph. The tornado continued into Will County at 1:01 PM CST.

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.
