A severe mesoscale convective system (MCS) that originated in central Kansas on the 17th progressed east and southeast into the Tennessee Valley during the afternoon of the 18th.  Several small scale bow echoes produced the strongest wind damage, while a larger scale gust front produced widespread sub-severe winds of 30 to 50 mph.  These winds still knocked large tree limbs and small trees down.  A swath of wind damage was reported across much of Lincoln County.  Another gust front produced numerous reports of damage in Franklin County.
