A potent storm system brought a prolonged outbreak of severe thunderstorms to the Lower Mississippi Valley region from the afternoon hours of New Years Eve lasting through the morning hours of New Years Day. This rare combination of high instability and wind shear is mainly what supported the large outbreak and multiple strong tornadoes. National Weather Service storm survey teams found 11 total tornadoes which occurred during this event. Of the 11, two were EF-3 with two more EF-2. Six were EF-1 with one EF-0. Damaging straight line winds also brought numerous trees and large limbs down across the area. Large hail also occurred during the event with reports ranging from quarter to golf ball size. In addition, flash flooding was a significant issue across the area. Roads were flooded in several locations, some vehicles were submerged in flood waters, and a few evacuations took place as a result of rising flood waters.
