Heavy rain developed along a stalled front across Northeast Arkansas early in the day causing flash flooding. This heavy rain eventually sagged into Northwest Tennessee resulting in some flash flooding there later in the day. As a day progressed a potent upper level disturbance moved out of the East Texas while a surface low pressure system tracked from Arkansas along the stalled front. Moist and unstable air moved into the Mid-South in advance of the stalled front and the developing low pressure system. As a result a line of showers and thunderstorms moved across West Tennessee during the evening hours of December 21st.  Several storms were severe with reports of damaging winds, hail and flash flooding.
