The outbreak produced strong tornadoes in Oklahoma, Texas, Louisiana, Mississippi, Alabama, and Georgia, resulting in severe damage and three fatalities.

[8] On December 12, the Storm Prediction Center outlined a level 2/Slight risk of severe weather for parts of Southwestern Kansas, Western Oklahoma, and Northern Texas.

On December 13, as the associated longwave trough ejected eastwards, the Storm Prediction Center outlined a level 3/Enhanced risk of severe weather across eastern Texas, much of Louisiana, and southwestern sections of Mississippi.

Environmental conditions were expected to favor the development of semi-discrete supercell thunderstorm structures, with an attendant risk for strong (EF2+) tornadoes.

[10] During the pre-dawn hours, a broken line of atmospheric convection with embedded supercell structures progressed eastward across North Texas.

Here, temperatures in the mid- to upper 60s Fahrenheit overlapped with dewpoints in the low to mid-60s, contributing to modest surface convective available potential energy of 500–1,000 J/kg.

Combined with strong shear profiles,[11] atmospheric conditions led to the development of several tornadoes across the Dallas–Fort Worth metroplex throughout the morning hours.

[16] All the while, the SPC renewed a level 3/Enhanced risk valid for December 14 across the Gulf Coast, continuing to highlight a large area for the potential of long-lived supercells capable of producing strong tornadoes.

[19] The potential for numerous tornadic supercells to develop prompted the issuance of a level 4/Moderate risk across southeastern Louisiana, southern Mississippi, and western/southern Alabama.

[24] This intense low-end EF3 tornado touched down west of Farmerville, initially snapping or uprooting numerous trees at EF1 strength, some of which ended up falling on multiple homes.

[119] The tornado then tracked back across Lake D'Arbonne before coming ashore at Corney Creek Drive and Dozier Road.

[119] Dozens of one-story brick apartment buildings were severely damaged and had large portions of their roofs torn off, and vehicles were flipped as well.

One apartment building sustained total roof loss and collapse of multiple exterior walls, earning a rating of EF3 with winds estimated at 140 miles per hour (230 km/h).

[119] After exiting the apartment complex and mobile home park, the tornado then entered another heavily forested area, most of which the not accessible to the National Weather Service damage survey team.

[119][120] A major blizzard occurred in the Great Plains related to the tornado outbreak, leading to heavy snow and freezing rain.

[123] On South Dakota Highway 37 in Parkston, a car crash occurred due to the icy roads, killing 3 people.
