What happened

The episode as NWS OHX wrote it up.

One of the worst tornado outbreaks ever recorded in the United States struck the Midwest, Ohio Valley, and Tennessee Valley from the evening hours on December 10 into the morning hours on December 11, 2021. Across Middle Tennessee, a total of 16 tornadoes were determined to have touched down, making this the 5th largest tornado outbreak on record in Middle Tennessee. These tornadoes injured 8 people across Middle Tennessee and caused millions of dollars in property and tree damage in many counties. These tornadoes, combined with the 5 tornadoes that occurred just a few days earlier across Middle Tennessee on December 6, 2021, set a new record for the number of tornadoes during the month of December. In addition, many counties that had tornadoes in December 2021 had never recorded a tornado in the month of December before, including Stewart, Humphreys, Cheatham, Wilson, Trousdale, Overton, Pickett, Coffee, and Grundy Counties.

.DISCUSSION...

Tornado Watch went out a couple of hours ago and so far, Middle TN
is good shape. However, the environment is changing from one hour
to the next, so things are become more and more favorable for
discrete development through 2 am. Surface based instability is
growing west of I-65, with 500 to 1000 J/Kg already in place.
Along with puh-lenty of deep layer and low-level shear (0-1km
SRHs values of 300-400), what is keeping us quiet right now is the
capping inversion. From the 00Z OHX sounding, there continues to
be a 750 mb cap that is keeping anything from growing out of
control here at home. West of us, it is very apparent that the cap
has broken and discrete supercells (already putting down a couple
of large tornadoes) have developed. Latest LAPS soundings suggest
that the cap is trying its darndest to erode over our far western
counties (it already has in West TN), so as these storms we're
seeing on radar to our west trek eastward, they should be moving
into an environment favorable to maintain their strength. The
current tornado-warned storm looks to miss Middle TN by a little,
but there is additional development directly behind it which could
threaten our western counties by midnight. The most important
thing is for folks to remain weather aware and keep their phones
on as they head to bed as these storms are truckin'. 50-60 mph
speeds mean you may only have minutes to get to shelter in the
event you go under a warning.

The second round of this night is still in the works and coming
together behind the storms I talked about above. We are still
expecting storms to conglomerate and become a QLCS with damaging
straight line wind potential, as well as isolated tornado spinups,
so while this first round could come to an end by the end of the
2 am watch, we won't be out of the woods until very late tonight
or tomorrow morning.

.AVIATION...
06Z TAF DISCUSSION.

No real changes from the previous discussion. A line of strong to
severe storms have formed out a head of the front. Damaging straight line
winds...tornadoes...possible strong...and even some large hail
will be possible. These storms have not cross the Tennessee River
as of 05Z. Have the line reaching CKV between 06-07Z...BNA/MQY
08-09Z and CSV around 12-13Z.

A wind advisory is valid from 03-08Z and this is reflected in the
TAFs with gusts to 35+ kts from the southwest. In addition with
such a strong gradient low level WS up to 50 kts is expected. CIGs
will be LIFR-MVFR before and during the front. Skies will begin
to clear and CIGs will begin to raise at CKV around 12Z BNA/MQY
around 18Z and not closer to 23Z for CSV. Winds will start out
southerly and become northwesterly after the FROPA.

west of I-65, but all of Middle TN could see damaging straight line
winds, isolated tornadoes, and hail. Storms could begin as early as
10pm and last through noon on Saturday. While brief heavy rainfall is
possible, flooding is unlikely.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.

Some strong to severe storms could still be ongoing Saturday morning
mainly along and east of I-65. The main threats with storms in this
time frame will be damaging winds.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will likely be needed. Please relay any
information about observed severe weather to the NWS while following

This major, long-track EF-3 tornado first touched down in Newbern near Washington Street in west Tennessee. The tornado moved northeast, uprooting and snapping numerous trees along its path. Several homes had significant roof damage. The tornado initially produced EF-1 damage but while progressing northeast, it continued to strengthen to EF-3 as it approached Dresden. Several buildings and homes in downtown Dresden suffered significant damage or were completely destroyed. The tornado slightly weakened and moved northeast toward Paris Landing and eventually crossed the Tennessee River. 5 people were injured in west Tennessee. The tornado clipped the Fort Donelson National Battlefield area of extreme southeastern Calloway County, Kentucky where it blew down several trees, then crossed the Tennessee River into the Land Between the Lakes area of Stewart County and did massive tree damage to heavily wooded areas uprooting thousands of trees along its path. The tornado struck a well constructed single family brick home near Bear Creek where it took off the roof and top story. It then continued to travel northeast where it passed Indian Branch and Morgan Branch where it continued to uproot trees and destroyed some farm outbuildings, lifted the roofs off of some single and double wide mobile homes and completely flattened some barns and single wide structures. The most widespread and severe damage in Stewart County was between Indian Branch and Morgan Branch to the south of Bumpus Mills. The tornado then continued northeast across the far northwest corner of Fort Campbell Army Base continuing to blow down trees before moving into Kentucky. The tornado received a maximum rating of EF2 in Stewart County, and 4 people were injured. The tornado passed just south of the city of Lafayette, Kentucky where it immediately struck a barn and knocked down several electrical transmission lines. The tornado tracked northeast over mostly open country before causing significant damage to several homes off of Boddie Road and Darnell Road. More significant damage occurred to several homes, farm outbuildings, and structures on Palmyra Road. A mobile home was completely demolished and significant roofing damage was done to a brick home on Herndon Oak Grove Road. As the tornado approached Interstate 24, mostly tree damage was observed with a few structures impacted as well. Once the tornado crossed Fort Campbell Blvd, additional damage to electrical transmission lines was observed including over a dozen wood poles snapped. The tornado continued northeast causing mostly tree damage before completely destroying four tobacco barns and damaging three equipment garages off of Bradshaw Road. Two other buildings were also heavily damaged along with multiple silos destroyed. Damage estimates were in the millions according to the owners for just this one farm. The tornado then took straight aim for the city of Pembroke where significant tree damage was observed along with multiple houses with roof damage. Once the tornado moved out of Pembroke, two mobile homes were completely destroyed with the occupants injured. The tornado then crossed into Todd County where mostly tree damage and damage to farm/outbuildings were observed. The tornado then lifted just before impacting the city of Elkton where straight-line winds became dominant. The tornado received a maximum rating of EF2 in Christian County and EF1 in Todd County, and 4 people were injured. The next tornado then touched back down just to the east across the Todd/Logan County line. Total path length of this tornado was around 123 miles.

Damage from this tornado started in northern Perry County with some uprooted trees and damage to an outbuilding noted along Crooked Creek Road. A swath of uprooted trees could also be seen on NASA satellite imagery between Crooked Creek Road and Highway 13 across the Walker Hollow and Lott Hollow areas. Continuing northeast, the tornado blew down more trees and damaged outbuildings along Red Bank Road before moving into Humphreys County, where a RV was overturned and roof torn off a barn along Highway 13. The tornado strengthened as it moved through rural forests towards I-40, with thousands of snapped and uprooted trees noted on high resolution satellite imagery near and south of the interstate. Crossing I-40 near mile marker 146 and Barren Hollow Road, the tornado continued blowing down thousands of trees as it pushed northeast. The tornado crossed into far northwest Hickman County and continued to blow down hundreds of trees along Duck River Road and Epperson Hollow Road before lifting west of Spence Hollow Road. Total path length of this tornado was around 15.16 miles. Based on newly available high resolution satellite imagery in March 2023, this tornado was upgraded to EF-2 due to the extreme tree damage between Highway 13 and I-40, and the path length and width were also increased.
