Selma–Old Kingston–Griffin supercell
The supercell that would go on to produce the Selma, Old Kingston, and Griffin tornadoes was first identified as a small non-severe storm near Palmetto, Louisiana around 6 am CST (12 UTC) on January 12. The storm moved steadily east-northeastward and crossed into southwestern Mississippi 30 minutes later, where it began to steadily organize as it passed near Woodville. The circulation within the mesocyclone briefly became strong as the supercell moved near Bassfield, but it, along with the supercell as a whole, weakened substantially shortly afterwards. No tornadoes touched down during that time, but some wind damage was reported. As the supercell approached the Mississippi-Alabama state line, it reorganized, becoming a severe thunderstorm as it moved into Alabama between Shubuta and Needham. The mesocyclone, while still broad, also began to increase in strength as the storm continued northeastward past Sweet Water and Catherine.

As the storm passed near Orrville, the rotation tightened significantly, and it produced its first tornado just northeast of the small town at 12:04 p.m. CST (18:04 UTC). This tornado would rapidly intensify as it moved northeastward, reaching high-end EF2 strength as it struck Selma. Peak winds from the tornado reached 130 mph and two people were injured. The tornado then weakened and dissipated southeast of Burnsville at 12:31 p.m. CST (18:31 UTC) as the mesocyclone briefly broadened. After crossing into Autauga County, the circulation reorganized and produced another tornado near Independence at 12:40 p.m. CST (18:40 UTC); this tornado would rapidly intensify and strike the Old Kingston community at mid-range EF3 intensity. Numerous mobile homes in the small town were completely obliterated, vehicles were heavily damaged or destroyed, and hundreds of trees were snapped, uprooted, and debarked. Seven people were killed in this area. The tornado would remain on the ground for 82.31 mi.

By the time the storm had crossed into Georgia, the QLCS behind it had caught up to it and caused the mesocyclone to broadened out and the circulation to weaken. However, the storm's energy was transferred southward and a new circulation formed southwest of LaGrange.

Clarksville, Tennessee / Allensville–Lickskillet, Kentucky
The tornado touched down approximately 5 mi south of Fort Campbell North, Kentucky in Montgomery County, Tennessee and moved northeast. After initially causing minor EF0 tree damage, the tornado quickly intensified to high-end EF1 intensity, completely destroying the Clarksville School of Fine Arts, inflicting heavy roof damage to homes and a church, and snapping several large trees. The National Weather Service did not release a specific rating for the school’s damage, but noted that the tornado “destroyed a building next to a church”. Further rapid intensification occurred, and the tornado reached EF2 intensity as it passed just north of SR 374 and through multiple neighborhoods in the northwestern city limits of Clarksville. Numerous poorly anchored homes in this area were shifted off their foundations and leveled, many other homes had their roofs partially to completely removed, and hundreds of trees were snapped. The tornado then further intensified to high-end EF2 intensity crested a hill and entered a heavily wooded area, where dozens of mobile and manufactured homes south of Britton Springs Road were completely obliterated with some being swept away with no debris left behind. The tornado killed three people here, including a ten-year-old boy. Additional homes suffered partial to total roof removal, another poorly anchored home was shifted off its foundations and leveled, and hundreds of trees were snapped.

Continuing northeastward, the tornado crossed a wooded area surrounding the Little West Fork Creek before strengthening to its peak intensity as it struck a subdivision just south of the West Creek High School. Four two-story brick and vinyl homes in this subdivision were completely leveled, with debris from the homes scattered 200 yd towards the northeast. All homes received ratings of EF3, with winds estimated at 150 mph. The National Weather Service noted that at this time, the tornado was “very narrow and intense” and they also noted that the homes were partially screwed and anchor bolted to the foundation, with mostly nails being used as the foundation anchoring. Other two-story homes in the area had their roofs partially or completely removed with exterior walls knocked down, including multiple homes that had its entire second floor removed, the nearby West Creek Elementary School sustained roof damage, and hundreds of trees were snapped as well.

At least a dozen outbuildings were damaged or destroyed of the county, including a silo that was blown over and barns that were leveled, and homes suffered generally minor to moderate roof and garage door damage, although at least one home suffered severe roof and exterior damage. Just before crossing into Logan County, the tornado crossed US 79 and moved through the southern part of Allensville at EF2 intensity. At least 51 structures were struck by the tornado with several outbuildings being destroyed, homes suffering moderate roof damage with some partial removal noted, and dozens of trees being snapped. Debris from the structures was blown into farm fields as the tornado continued into Logan County. The tornado weakened to EF1 after crossing into the Logan County, damaging crops, trees, and outbuildings. It strengthened again to low-end EF2 intensity as it struck the community of Lickskillet, where every structure was damaged. A well-built two-story house in the town sustained extensive roof damage, had its foundation shifted, windows blown out, and three vehicles thrown and severely damaged. Two barns were also destroyed with the impalement of barn boards into the home noted. The tornado then weakened back to EF1 strength as it moved further northeast, but continued to inflict severe roof damage to homes, damage or destroy outbuildings, and snap or uproot trees for several more miles. The tornado then struck the community of Williams Store along KY 96 at EF1 intensity, damaging multiple homes and outbuildings, including one home that had parts of its middle section blown out. The tornado then continued moving northeastward at EF0-EF1 intensity, causing additional damage to homes and trees and damaging or destroying more outbuildings as it crossed US 431 and KY 100 south of Russellville.
