An upper level longwave trough emerged out of the Intermountain West and into the Central and Southern Plains during the daytime and evening hours of January 10th. A strong southerly return flow commenced out ahead of the trough during the 8th-9th, allowing for unseasonably warm and humid conditions to advance northward across Southern Oklahoma, much of Central and Eastern Texas, as well as Louisiana, Arkansas, and the Lower Mississippi Valley. Meanwhile, an intensifying surface low pressure system and associated dry line developed along the Red River of North Texas into Southern Oklahoma during the afternoon hours, which spread east northeast across the Ark-La-Tex during the early morning hours on January 11th. With afternoon temperatures climbing into the mid 70s ahead of this trough, moderate instability developed across the broad warm sector, with very strong wind shear in place as large scale forcing increased ahead of the trough axis across East Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana. Thus, an axis of strong to severe showers and thunderstorms developed during the evening hours across Southeast Oklahoma, adjacent sections of Southwest Arkansas and East Texas, which advanced east into North Louisiana during the early morning hours of the 11th. Widespread damaging winds downed trees and power lines across much of Northwest and Northcentral Louisiana, with even a long track tornado developing along the line of severe thunderstorms across Central Bossier, Southern Webster, and Southern Claiborne Parishes. Another isolated tornado touched down in Western Union Parish, before these storms exited the region shortly before daybreak on the 11th. Unfortunately, these storms resulted in four fatalities  across Northwest Louisiana, three of which occurred from the Haughton tornado.

This is a continuation of the Southern Webster Parish EF-2 tornado. This tornado continued on the ground intermittently east-northeast throughout Southern Claiborne Parish, snapping and uprooting numerous trees as it crossed Harris Road, Old Arcadia Road, Faulk Road, Sherrill Road, and Highway 154 south of Athens. The tornado produced partial roof damage to approximately a half dozen chicken houses and shingle and partial roof damage to several other structures, especially off of Buckner Road, Cook Road, and Highway 519 before finally lifting. In addition, widespread straight line winds estimated at 90-100 mph along the path of the tornado led to extensive tree damage. Estimated maximum winds from this tornado throughout Southern Claiborne Parish ranged from 90-105 mph, consistent with an EF-1 tornado but weaker than the estimated maximum winds near 135 mph that was surveyed in Eastern Bossier Parish. The total track length of this tornado when it initially touched down in Central Bossier Parish to when it lifted in Southern Claiborne Parish was just under 41 miles.

This is the continuation of the Bossier Parish EF-2 tornado. This tornado weakened slightly as it crossed Pilgrim Rest Road, and tracked northeast before entering the southern sections of Doyline, downing hundreds of trees as it crossed Highways 163 and 164, before entering the extreme southeast corner of Camp Minden. The tornado then tore through the town of Sibley and the northern fringes of Dubberly, where it downed trees and power lines, damaged a metal barn, the roof of a home, and destroyed a shed on Wallraven Road. An 18-wheeler trailer was overturned at the South Webster Industrial Park in Sibley, and a building, fencing, and equipment were damaged at an oil field service company at the park. Just before the tornado crossed Interstate 20 between exits 49 and 52, it developed a much wider swath of damaging straight line winds with its rear flank downdraft near and just south of the tornado track. In fact, a large sign was blown over onto an 18-wheeler at Love's Truckstop at I-20 Exit 49 (Highway 531). After it crossed Interstate 20 southeast of Minden, the tornado then rolled a single-wide mobile home on Fuller Cemetery Road near the Nine Forks community and damaged the roofs of two structures before it moved into Southwest Claiborne Parish. The tornadic winds as it tracked through Southern Webster Parish did weaken slightly from its estimated maximum winds in Eastern Bossier Parish, and ranged from 95-110 mph, which is in the EF-1 range. At least 120 broken power poles and over 250 spans of downed wire were the result of this tornado and associated  widespread damaging winds near Doyline, Sibley, Dubberly, and Minden. Significant damage was done to the major power distribution lines that feed the town of Sibley and the South Webster Industrial District.

A long track 40+ mile long EF-2 tornado with estimated maximum winds near 135 mph first touched down just south of Barksdale Air Force Base off of Sligo Road in Central Bossier Parish, where it snapped and uprooted hundreds of softwood and hardwood trees and damaged several carports and outbuildings. The tornado then crossed the far southeast corner of Barksdale Air Force Base where at least one hundred trees were snapped or uprooted. After the tornado exited the corner of Barksdale Air Force Base, it strengthened south of Haughton to produce its most significant damage, completely destroying a single-wide manufactured home and a double-wide manufactured home off of Davis Road. Two fatalities (a 79 year old male and his 65 year old wife) occurred in the double-wide with an additional fatality (an 87 year old male) occurring in the single-wide. The tornado continued to produce roof damage and uproot and snap trees which fell into homes in Eastern Bossier Parish, concentrated most along James Lane. The tornado continued moving northeast across Oliver Road and Camp Zion Road, where numerous trees were snapped and uprooted, while also removing siding off of a single-wide manufactured home, and ripping a portion of the metal exterior and doors off of the Bossier Parish Fire District 1 Station 6 building, as well as tearing off some vinyl siding to a mobile home living quarters located next door, before crossing over into Webster Parish.

An EF-1 tornado with estimated maximum winds near 107 mph touched down on the east side of Highway 550 between Milton and Mariola Road. Here, it uprooted and snapped softwood trees, before continuing northeast in the embedded squall line which was also doing wind damage along both sides of the main tornado path. The most significant tornado damage occurred along Clayton Foster and Christine Roads, where it completely tore off the metal roofs from two chicken houses, and snapped and uprooted several hardwood and softwood trees. Additional chicken house damage occurred on the south end of the tornado closer to Christine Road, where a portion of the tin roof was peeled back, and metal roofing was thrown hundreds of feet along the main tornado path. The tornado finished its life cycle along Thomas Wade Road, where it ripped more metal roofing from chicken houses, and tossed them in a southerly direction away from the main circulation. The tornado lifted at this location, although areas near and east of Highway 15 continued to experience straight line wind damage along the path of the squall line as it moved across Central Union Parish.
