A powerful cold front and upper level system combined with a weakly unstable, moist and highly sheared environment to produce severe thunderstorms and a tornado. A quasi-linear convective system (QLCS) developed during the morning hours across the mid South and raced eastward at 50 to 60 mph. The storms arrived in northwest Alabama during the mid morning, weakened, then reintensified during the midday hours in north central Alabama.  The storms continued tracking east and exited the state by late afternoon.  One of the storms produced an EF-1 tornado that tracked near the Tennessee state line in Madison County.  Other storms produced wind damage and large hail reports.
