December 9 event December 10 event Clarksville, Tennessee/Allensville–Lickskillet–Auburn, Kentucky This intense tornado formed approximately 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 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 or completely removed; and hundreds of trees were snapped. One woman was fatally injured when her mobile home was destroyed, dying of her injuries a week later. 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 obliterated, including some that were swept away with no debris left behind. Additional homes suffered partial to total roof removal, another poorly anchored home was shifted off its foundations and leveled, and hundreds more trees were snapped. 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. 114 homes were destroyed (all of which were in Clarksville) while another 857 were damaged, and at least 20,000 people were without power after the tornado in Clarksville alone. The tornado also caused $45,000 in uninsured damage to the Clarksville School of Fine Arts.
Madison–Hendersonville–Gallatin–Castalian Springs, Tennessee This strong tornado was first observed by numerous storm spotters and residents at 4:39 p.m. CST (21:39 UTC) before tracking through areas of the
Nashville metropolitan area. The tornado initially formed near Trail Hollow Lane, just to the east of
I-24. It tracked east-northeast, causing minor EF0 damage to trees and residences. This was the first time a tornado had directly struck a Nashville Electric Service power substation since the
1974 Super Outbreak. The tornado continued past the substation and crossed US 31E while fluctuating between EF1 and EF2 intensity, heavily damaging or destroying homes and warehouses, and snapping or uprooting trees and power poles. The tornado continued northeastward and reached its peak intensity of high-end EF2 as it moved along and over the
Cumberland River and
Old Hickory Lake into the western part of
Hendersonville in
Sumner County. Hundreds of trees were blown down at the
Old Hickory Dam, multiple buildings and warehouses at the dam site and a nearby marina were heavily damaged or destroyed; and a microwave tower was crumpled to the ground. The tornado then began to fluctuate between EF1 and EF2 intensity again as it approached and moved through the center of Hendersonville along US 31E, with a
tornado emergency being issued as the tornado entered the town. Heavy damage occurred throughout the town, with multiple businesses at a strip mall reporting heavy roof damage with exterior wall collapses, several warehouses, other businesses, and outbuildings being heavily damaged or collapsed, homes suffering severe roof, siding, and exterior wall damage, and dozens of trees and power poles being snapped or uprooted. One two-story home in the area also had its entire roof removed, causing severe damage to the second floor's exterior walls. Past Hendersonville, the tornado weakened to EF1 intensity again and caused more sporadic damage, mainly in the form of fallen trees and snapped power poles. Some homes and businesses suffered roof and siding damage, and a barn was heavily damaged, with debris from the structure damaging a home. Two homes near the
SR 386/US 31E interchange suffered heavy roof damage, with one of them also having its garage cave in. As the tornado approached Station Camp Creek, more homes, apartments, and condos were damaged, including another two-story home that had the second-floor roof removed, a gas station canopy was blown over, and more trees were snapped. One small area of EF2 damage was noted with a metal truss tower that collapsed. while the one in Hendersonville served power to customers, though it needed repairs. == Non-tornadic effects ==
