Strong surface low pressure tracked from the Plains into the Mississippi River Valley while a strong cold front pushed into the Mid-South on December 23, 2015. A very moist and unstable airmass moved into the area as a warm front lifted north through the region during the early morning hours. A potent upper level disturbance help to trigger thunderstorms along and in advance of the approaching cold front. The necessary ingredients were in place for storm to intensify to severe limits. There were several reports of large hail, damaging winds and flash flooding across West Tennessee during the late afternoon. A violent long track tornado moved from into parts of Hardeman and McNairy Counties from North Mississippi during the early evening.
