Supercells in northern Mississippi transitioned into a quasi-linear convective system (QLCS) which progressed eastward through northern Alabama.  The storms produced a few bow echoes and meso-vortices, which spawned a few tornadoes and produced widespread wind damage in northwest Alabama (mainly west of I-65).  As the storms progressed eastward, the gust front began to outrun the storms, yet still produced sporadic wind damage.
