Tornadoes and Flash Flooding in Kentucky, December 10 to 11, 2021

December 10 to 11, 2021 · NWS LMK · 54 events in 29 counties and zones

Strong southern winds brought warm temperatures and plenty of moisture into an environment of strong wind shear ahead of an advancing cold front. This resulted in unusually warm temperatures for a December day and the ingredients to produce a historic tornado outbreak and flash flooding.

What happened

The episode as NWS LMK wrote it up.

Strong southern winds brought warm temperatures and plenty of moisture into an environment of strong wind shear ahead of an advancing cold front. This resulted in unusually warm temperatures for a December day and the ingredients to produce a historic tornado outbreak and flash flooding. This included multiple long track tornadoes. Central Kentucky saw 18 tornadoes that injured 96 and killed 18. An additional death occurred in a flash flood.

What forecasters said that day

.Forecast Update...
Issued at 750 PM EST Fri Dec 10 2021

Tornado Watch #554 has been issued for the western two-thirds of our
CWA until 3 AM EST. Scattered pre-frontal convection has already
developed across the lower Ohio/Mississippi River confluence and
will quickly race northeastward into our western CWA within the next
hour. The VAD wind profiler data from VWX/HOP radars have shown
increasing low level wind shear resulting in very strong helicity in
the lowest 1 km (resulting in >400 m2/s2). Model soundings along our
far western CWA do show a bit of an inversion and farther east
toward the I-65 corridor we are seeing that inversion show up on
AMDAR soundings. RAP soundings over the next few hours show dew
points slowly increasing west of I-65, which may be enough to allow
those storms to become surface based when they move into the CWA.

Do want to convey that we expect another Watch will be needed
farther east in our CWA for the pre-dawn and around sunrise time
frame, but that will likely come at a later time tonight.

.Short Term...(This evening through Saturday)
Issued at 344 PM EST Fri Dec 10 2021

...SIGNIFICANT EPISODE OF SEVERE WEATHER EXPECTED TONIGHT AND EARLY
SATURDAY MORNING...

====================================
Synoptic Discussion
====================================

Deepening mid-level trough axis over the Plains will translate
eastward this evening and overnight.  The trough axis is forecast to
remain positive to neutrally tilted as it moves toward our region.
Initial mid-level vorticity lobe moving NE across KS/OK this
afternoon will lead to initial convective development across
MO/AR/WKY/WIN/SCIL as early as late this afternoon/evening.  Deep
tropospheric wind fields are expected to overspread the Ohio Valley
along with a strengthening low-level flow that will transport
deep/rich Gulf moisture northward into the region.  The net result
of this combination of increasing instability and shear will lead to
a severe weather episode over the Ohio Valley tonight and early
Saturday morning.  Damaging winds in excess 60 MPH and isolated to
scattered reports of tornadoes are expected.  In addition, copious
amounts of moisture will lead to heavy rainfall which may result in
some minor flooding issues across the area.

====================================
Meteorological Technical Discussion
====================================

Surface warm front is rather diffuse this afternoon, but boundary
looks to be crossing through the region at this time, based on band
of elevated convection oriented from W/C IN southeast through
eastern KY.  This activity will continue to move to the northeast
this afternoon.   Once this activity clears out, we will be in the
open warm sector with moisture advection continuing through the
evening hours.  Dewpoints are currently in the mid 50s across the
region but are approaching 60 in our southwest areas.  A stronger
dewpoint surge is currently in progress out along the MS river and
dewpoints have already risen into the upper 60s over far southwest
Kentucky.

In the near term, a mid-level short wave evident in the GOES
moisture channel was moving NE across OK/KS. This feature will
translate northeastward into the Midwest this evening.  This feature
will likely lead to initial convection firing over AR/MO/WKY/WTN and
SCIL later this afternoon/evening.  Further east over our area,
continued moistening and theta-e advection will continue across our
region.  The front edge of a strong low-level jet axis will work
northeastward into very lower part of the Ohio Valley.  As this
occurs, additional cooling aloft is expected to overspread portions
of SWIN/WKY which should allow higher instability to develop as mid-
level lapse rates steepen.  These two items will also help erode the
elevated mixed layer of warm air aloft and result in a possible
uptick in surface based convection across our western CWA this
evening.  Given the parameter space, initial cells that develop will
like be discrete/scattered and given the shear profiles a mix of
multicell and supercells are expected.  These storms will likely
race off to the northeast at 55-60 MPH.  Threats with this activity
will be damaging winds, perhaps some marginally severe hail, and
isolated tornadoes.

Many members of the various short range ensemble models generally
support this idea, i.e., more members that not.  However, the
eastward extent of pre-frontal convective development this evening
remains uncertain due to unknowns involving how much of the EML will
erode and whether surface based convective inhibition will remain.
In general, the best chances of convective development this evening
will be in areas along and west of the I-65 corridor.

Later in the overnight, it appears that additional convection will
develop given the instability and deep forcing resulting in more of
a linear QLCS.  Given the strong shear and substantial front-
parallel components of the deep layer flow, downward momentum
transfer should yield instances of wind damage within the convective
line. Additionally QLCS mesovortices within the squall line where
bows and surges develop may produce several instances of embedded
tornadoes.  This line will work through region during the late night
hours and continue into our eastern sections after sunrise Saturday.
The expected progressive nature of this line should result in
generally short residence time of heavy rainfall over any one
particular area.  Additional QPF information may be found below in
the Hydrology section of the discussion.

We will continue to monitor observational data closely this
afternoon and evening especially upstream.  As cells develop and the
convective evolution becomes more certain, we will be able to update
our timing and speak a bit more confidently with regards to the
possible magnitude of this severe weather event.

====================================
Important Messaging
====================================

As we have mentioned over the past 24 hours, we want to stress the
danger in the overnight severe weather potential.  Historically,
tornadic and widespread severe weather events in the month of
December are rare, although we've had a couple of events in the last
10 years (12/2013 and 12/2015).  We would like to emphasize the
following topics:

1. Have multiple ways to get warnings overnight.  Leave your cell
phone on and have WEA alerts turned on.  Check the status of your
weather radio and make sure it is functioning.  Charge/replace
batteries in your alert devices.

2. Review your severe weather plans for your household.  Review
where your lowest level interior rooms in your home are and have
space ready in there to shelter. Put as many walls as you can
between you and the outside of your home.  If you have a basement,
make sure a shelter space in an interior room or under substantial
framing is available and ready in the event of a warning.  Stay away
from exterior windows and doors.

3. If you live in a mobile home, consider finding a more substantial
shelter this evening with friends and/or family.  Even in non-
tornadic winds, gusts of 60+ MPH can easily flip mobile homes
whether they are tied or bolted down.

4. These storms will be moving quickly with speeds of 55 to 60 MPH.
Warning lead time on these storms could be a challenge especially
involving mesoscale vortices within the anticipated squall line.

.Long Term...(Saturday night through Friday)
Issued at 320 PM EST Fri Dec 10 2021

After an stormy start of the weekend, the latter part of the
forecast will certainly be more relaxed. Ejecting upper wave will
give way to anomalous ridging aloft and surface high pressure for
the easternmost two-thirds of the CONUS. Meanwhile, upstream flow
will feature a series of digging troughs which will slowly advance
towards the central US by midweek, eroding the high-pressure dome.

Sunday-Monday... Morning temperatures both days will be below
freezing thanks to a combination of CAA and radiational cooling.
Afternoon highs will gently move from the upper 40s on Sunday to the
lower 50s at the start of the work week. A dry air mass in place
secures clear skies and plenty of sunshine as the surface high
pressure moves to the Mid Atlantic states and an West Coast trough
moves to Central Plains.

Tuesday-Wednesday...The aforementioned large scale configuration
imposes a southerly wind and accompanying increased theta-e
advection. As a result, temperature readings will progressively
climb and the forecast reflects maximum temps around the upper 60s
south of the Parkways by midweek. Expect winds to start picking up
on Wed with gusts in the 10-15 mph range while cloud coverage spread
our area.

Thursday-Friday...As the Central Plains trough progresses to the
Midwest/Great Lakes region, it pushes an attendant cold front to the
Ohio Valley. However, strong ridge aloft anchored over the SE CONUS
will inhibit further southward momentum of the baroclinic zone,
therefore, it could stall south of our area or right above us. There
is still some timing uncertainty with this evolution as noted in the
WPC mid-level EOF cluster patterns. That being said, there is
increasing agreement for warmer temps on Thursday which could result
in record high low for SDF. The latest NAEFS ESA guidance has 850-mb
temps around the 90th climo percentile. Winds gusts will be blowing
from the southwest around 15-20 mph on Thursday as the front sweeps
by central KY and diminishing by Friday. Finally, precipitation is
boosted for the end of next week and probably next weekend with the
frontal passage and subsequent stalling nearby. This scenario is
also reflected by the slight risk of heavy precipitation delineated
by CPC during the Dec 17-20 timeframe as return flow from the GoM
leads to high rain chances.

.Aviation...(00Z TAF Issuance)
Issued at 649 PM EST Fri Dec 10 2021

IMPACTS:
- Low stratus early this evening with scattered showers
- Southerly winds increase become gusty tonight
- Gusts tonight and overnight of 30-35kt
- Strong to severe thunderstorms moving through overnight
- Strong/gusty southwest to west winds will be seen on Saturday
behind a cold front

DISCUSSION:

A strong storm system will approach and pass the region during this
TAF cycle, strong & impactful storms, gusty gradient winds, low
ceilings at times. In addition, the most intense thunderstorms will
briefly reduce visibilities below 2 SM.

For the evening and overnight period, we expect scattered convection
to develop over the next 1 to 2 hours across western KY and
southwest Indiana. After scattered storms (some supercells), these
storms are expected to organize into a well developed squall line
that will race across the region. While not explicitly defined in
the TAFs, localized gusts over 50kts can be expected in this line in
some areas. Additionally wind fields aloft are very strong and LLWS
is expected at all the terminals this evening and into the overnight
period.

Convection should clear the terminals around or just after sunrise
Saturday however, scattered rain showers and gusty southwest to
westerly winds are expected throughout the day.

CONFIDENCE:

Medium-high on all elements.

.Hydrology...
Issued at 320 PM EDT Fri Dec 10 2021

Deep, moist SW flow characterized by PW~1.5" is being advected along
the warm sector ahead of an amplifying upper-level trough. Attendant
cold front will swing through our area Friday night/Saturday morning
bringing a strong-to-severe line of thunderstorms. Heavy rain from
this event might provoke localized flooding and river flow rises,
especially streams that experienced flow peaks during the last event.

Current forecast package is considering QPF in the 1-1.5" range
associated with the main frontal passage. Meanwhile 3-hr FFG sits
between 2-3" area-wide and the 0-40 cm soil moisture is still
average per the latest NASA SPORT analysis. Therefore, rainfall
should be largely managable giving minimal runoff. Additionally,
HREF 1-hr probabilities for QPF greater than 1" is less than 20%,
which aligns well with the progressive nature of the system. Only
problem for stagnant water is in poor drainage areas and low-lying
locations. WPC still manintains a Marginal Risk (1 out of 4) of
excessive rainfall due to the strong linear forcing, theta-e
advection, and any localized areas of training convection given the
alignment and strenght of the LLJ and the cloud-layer mean wind.

Another factor to consider is the antecedent hydrological conditions
of rivers that experienced flooding/rises this past Monday and
respond quicly to short periods of heavy precipitation, such as:
Rochester Ferry, Paris, Peaks Mill,and Boston. Other rivers worth
monitoring during the next 24 hours per the lastest AHPS/HEFS
forecast are the Green and White Rivers. It is important to mention
that the OHRFC does not expect any widespread risk of significant
river flooding.

This tornado is a continuation of the western Kentucky (Mayfield) tornado and will go down as the longest continuous tornado track on record in the Commonwealth of Kentucky at 163 miles (plus another two miles in Tennessee). This tornado developed in Obion County, Tennessee near Woodland Mills Road before tracking to the northeast through western Kentucky and on into central Kentucky (see Storm Data from the Memphis, Tennessee and the Paducah, Kentucky offices for more information on the beginning portion of this tornado). The tornado finally came to an end in Grayson County, Kentucky at Rough River Dam State Park. This is the first of five segments of this tornado in the Louisville, Kentucky County Warning Area. The tornado was at EF-1 strength when it crossed the Green River from Muhlenberg County into Ohio County. The tornado retained EF-1 strength through an abandoned coal strip mine, snapping hardwood trees, overturning a large section of coal conveyor belt, and downing steel and wood power poles. Rugged terrain seems to have affected the tornado at times as it fluctuated in width and intensity moving across A9 Road, to Matanzas Road, and approaching A5 road. It weakened to around the EF-0/EF-1 threshold and narrowed to 200-300 yards as it crossed A5 Road and A6 Lane, before rapidly intensifying to EF-2 strength over Chandle Loop and Highway 85. Here, a large chicken farm lost 5 out of 7 of its well built chicken houses. The foundations were swept clean. In addition, several homes and barns suffered major damage or total destruction. Hundreds of large hardwoods were snapped and uprooted. One well built house had a large portion of roof removed along with partial wall collapse. Max width in this area was around a quarter mile. The tornado maintained solid EF-1 strength and narrowed to a width around 300 yards as it briefly paralleled Carter Ferry Road, and then approached and crossed A7 Road. From here, a significant topography change occurred as the tornado crossed the Rough River and entered much flatter open farmland. Damage was noted to a grove of snapped hardwood trees near Johnson School and Mud College Roads. Then, several (6 or 7) large steel electrical transmission lines were either broken or bent across a widening half to almost three quarter mile wide width. The tornado had gained significant intensity up to EF-2/EF-3 strength as it slammed into homes and businesses along US 231 only about 1 to 1.5 miles NW of Hartford. On the west side of US 231, two semi tractor trailers were lifted, twisted, and thrown 40 yards from their original position, badly mangling one of the cabs. In addition, a barn was completely demolished. A small, brick office structure was totally destroyed only leaving one half of a wall and a few interior rooms, while completely wiping away the other half of the building. Winds peaked at an estimated 140 mph here. Across the highway a well built, and nearly 100 year old, brick two story home lost its entire roof and collapsed a couple of upstairs walls. Other homes, very large silos, small businesses, and a fertilizer storage facility were heavily damaged in addition to some very large and healthy hardwood trees being snapped, twisted, and snarled. The tornado maintained EF-2/EF-3 intensity as it continued northeastward, crossing the William H Natcher Parkway and approaching Highway 69. Here, more intense damage occurred along 69 between Utley Road and along Morrison Run. At Utley Road, 2 homes and 1 double wide trailer were completely destroyed, and a 4th brick home lost an entire roof and collapsed a couple of walls. Here, an amazing survival story occurred as the residents of the 3 structures that were completely destroyed hunkered in the bathroom of the brick home and rode out the intense tornado. Luckily, no injuries occurred thanks to the great decisions made by the occupants to find a sturdier structure to ride out the storm. A large barn was also heavily damaged here. The next set of homes downstream from Utley Road experienced very intense damage. Here, two anchored mobile homes were completely destroyed as their frames were tossed and bent. One frame ended up 100 yards from its original position. A fifth wheel camper was thrown and landed upside down 30 yards from where it sat. A small farmhouse was also heavily damaged as some walls completely collapsed. Another survival story occurred here as residents made a decision to leave the area to seek better shelter. Many compliments were given to local television media coverage and warning lead time. Two more homes were either heavily damaged or destroyed as the tornado crossed Highway 69. A well built two story home lost half of its upper story, and a small brick home was sheared in half. Damage was observed by NWS surveyors to several hardwood trees along Morrison Run from Cedar Grove Road. However, the most intense tree damage of the Ohio County path occurred along Humble Valley Road where some local terrain influences very likely funneled the tornadic winds into a consolidated area. Here, strong EF-2 to near EF-3 winds snapped thousands of hardwood trees and damaged a few homes, barns, and sheds. It took 2 to 3 days to clear Humble Valley Road for access. A barn was destroyed, along with tree damage, and complete destruction of a home under construction along W Halls Creek Road. As the tornado continued toward the intersection of highways 878 and 919, it crossed Bean Hill doing mainly tree damage. It then did major tree damage, unroofed a home, and destroyed a barn at that intersection. Heavy damage occurred at New Baymus Road where a farm lost three substantial barns, and a deer farm was heavily damaged along with a bunch of equipment. Clinton Lane was the next to be hit as a brand new barn, power poles, and a few structures were damaged or destroyed. The barn was totally destroyed and thrown hundreds of yards downstream, and hundreds of hardwood trees were snapped. One cow was killed by flying debris here. Downwind of that, a trailer was cut in half amongst very heavy tree damage, and the occupants of the mangled half of the trailer had fled to a safer shelter. Hundreds of hardwoods were snapped around Cane Ford Lane along with total destruction of an old trailer. From there, the tornado climbed a ridge and crossed Highway 54, heavily damaging a home and garage, along with continuing to mangle hundreds of hardwood and softwood trees.

As the tornado entered Grayson County, the path crossed the Rough River about 1 mile WNW of the Lafayette Golf Club. The tornado snapped several hardwood trees in this area before moving almost a half mile across an open flood plain. The tornado then continued northeast through a heavily wooded area, continuing to snap and uproot hardwood trees along the path. There some strong EF-1 intensity damage happened in a development area a mile north of the Falls of Rough State Resort where intense snarling of a cluster of hardwood trees was indicative of winds just over 100 mph. A well built structure was mostly spared as an inflow vortex fed into the main tornado path around the southeast side of the house. Extensive tree damage occurred in this area where over 100 hardwood trees were snapped and uprooted.

This tornado formed approximately 1 mile southwest of Crossroads near Watlington Road and tracked northeast for approximately 22 miles before crossing into western Warren County. The tornado continued approximately 6 miles into Warren County before dissipating at 0114 CST. In Logan County, the supercell that had cycled down its tornado in eastern Todd County (but continued to produce wind damage northeast of Elkton) spun back up again soon after crossing the border into western Logan County. It quickly ramped up to EF-3 (140 mph) intensity with a damage swath roughly three quarters of a mile wide along Milton Sharp Rd. On the southern side, a family was home when a 2 by 4 narrowly missed the husband as the roof was being peeled off the middle of the house. On the north side, a large dairy farm was completely destroyed. As the tornado continued northeast, a wide swath of trees was snapped/uprooted along the edge of a forest on the southern edge of the vortex, while on the north edge a well built home had its second floor two-thirds thrown off. A male was in the other section when a 2 by 4 from the first floor came up and got lodged in his mattress. Another well built log cabin in this area lost its second floor roof. The tornado then turned more ENE in the Buena Vista Rd area. A doublewide manufactured home was completely destroyed here along with several outbuildings on the property. A male at the home received warning from family and heard the tornado approach, getting into a bath tub in the middle of the east side of the structure. After it hit, the home blew into a row of trees and the male remembers grabbing onto a tree southeast of his original location. He sustained injuries as medics had to get wood out of his legs. The tornado continued over to Lakewood Ln where a boy was in the second story of a house when the window imploded inward and moved the bed he was in. After this, the storm crossed US 431, impacting several trees along Hwy 1040 with EF1 level winds. It then moved to a row of mobile homes along H.C. Johnson Rd. Two of these homes were completely destroyed, with one blown into a row of trees south of its original point and another lifted up and over a tree just east of its original location. This may have been a mesovortex spinning around the main circulation. The tornado damage was widest at this location, roughly 0.8 mile. On the south side of the tornado, a mobile home was completely destroyed along Hwy 915 where it was spread out over the road. The resident was a female whose father insisted she stay the night at his place, with a basement, after hearing the messaging in the days before. That same mesovortex may have been what caused the collapse of an electric transmission line just east of Marshall Rd where there was little damage to surrounding trees. Farther north on that road a well built brick home had its roof taken off as well as the carport removed. The tornado continued to track along Hwy 79 towards the Chandlers Chapel area where the Methodist Church lost its steeple and had damage to several of the stained glass windows. A couple of homes had major damage here. A resident said he had at least 20 minutes of warning lead time ahead of the touchdown. There was additional damage along Turner Road and then 3 Poplars Rd. This survey ended soon after 3 Poplars Rd. Another survey was conducted in the far northeast corner of Logan County where a couple of long chicken barns were leveled.

The National Weather Service in Louisville surveyed a tornadic supercell over the course of 6 days in Warren County which directly struck Bowling Green. The tornado first touched down in rural southwestern Warren County just south of the intersection of Wimpee Smith Road and Petros Browning Rd. It tracked to the northeast for approximately 26 miles before entering Edmonson County. The tornado continued approximately 3.6 miles into Edmonson before dissipating at 0138 CST. At the tornado's beginning in Warren County, the tornado twisted, snapped, topped and uprooted softwood and hardwood trees. The tornado was about 200 yards wide, with EF1 winds of 90 mph. Aerial photography confirmed the tornado was continuous in this rugged area of southwest Warren County. The tornado increased to EF2, between 120 and 125 mph, doing major damage to several older barns along Tommy Smith Road. It threw a 1700 pound cattle trailer, 300 yards into a creek ravine.The NWS drone showed a distinct narrow main funnel within the larger funnel. This 30 to 35 yard funnel was clearly seen scouring the corn field and produced the most concentrated damage. The narrow funnel crossed Browning Rd and hit a well constructed house. The only major part of the house that survived was an interior bathroom and hallway. Winds were estimated at 135 mph, and areas outside the narrow funnel had damage of 100 mph, and the entire overall width was 250 yards wide. The survey team found extensive tree damage along Van Meter Rd and Fuqua Rd and aerial photography confirmed the tornado was continuous in this rugged, mainly forested area. The tornado did minor roof damage to some homes along Blue Level Road with winds of 86 to 90 mph but did more substantial roof and side damage to several barns with winds of 90 to 95 mph. Based on drone technology, there appeared to be two distinct areas of damage, and likely had a smaller satellite tornado. There was extensive roof damage to the Zomi Agape fellowship center with insulation thrown both downwind and on the upwind side of the building. The tornado increased in speed when it was over Old Tramm Rd by Rembrandt Court and Powell Road. One house on Rembrandt Court was knocked off its foundation by the garage attachment and slid about 15 feet. Other homes were knocked down to just interior bathrooms and hallways remaining, but there were some foundation construction concerns. EF2 winds of 130 to 135 mph were evidenced in this area. Several houses were knocked down to the foundation, but there were foundation construction concerns. In addition, farm equipment from a barn on the right side of Powell St was thrown directly into homes on the left side of Powell Rd. The survey team found significant house damage to dozens of homes in the Creekwood subdivision. This included exterior collapsed walls, roofs blown off, foundations severely compromised, garages blown in, insulation blown on all four sides of houses, and garages severely damaged or destroyed. In fact, they were dozens of double garages damaged, where one garage door blew in and the other garage door blew out. There were hundreds of powerlines and snapped power poles down throughout the county. Trees were uprooted snapped and twisted facing in all directions. Dozens of cars were flipped, twisted, turned, and thrown into homes. 2 x 4s were thrown into the ground, like missiles. Several splintered boards were impaled into vehicle windshields, tires, and along the hood grills. Most of the damage was rated EF2 from 115 to 135 mph except for 8 homes near Mossy Creek. The survey team brought in engineers from WKU to look at 8 homes, which were wiped down to the foundation from Moss Creek to Mossy Stone. Engineers helped in determining winds speeds were 160 mph for these houses, a high EF3 rating. Tragically, several fatalities occurred in the subdivision area. The tornado was 250 yards wide in Creekwood, but increased to about 350 yards wide before crossing Veterans Parkway. The tornado crossed the William Natcher Parkway and hit large townhouses along Veterans Parkway. There were numerous windows shattered and some roof damage. One of the town houses was shifted off the foundation, but there were no bricks or other support on it. The tornado crossed Russellville Rd hitting many businesses. At Royal Motor Cars, several storage buildings were destroyed, major loss of roof panels at Cabreras Mexican restaurant and an auto parts store. At Plumbers Supply company at 2321 Russellville Rd. The garage was blown in and collapsed. The main building had a shifted foundation, and a partial collapse of some exterior cinderblock walls, tractors and trailers were twisted and flipped, and there was numerous power poles snapped. The Shell gas station had major damage to service station canopy and store, as well as walls of an Enterprise car rental. The tornado increased to quarter mile wide and went from EF2 of 130 mph, from Royal Motorcars to AutoZone, and then decreased to EF2, 115-120 mph and narrowed to 1/8th of a mile with major tree and roof damage along Lealand Street, Cedar Ridge, and University Drive. A fully loaded dumpster was thrown 250 yards. At Russell Road and Springhill Avenue, a Marathon gas station had its pumps destroyed, and most of the exterior walls were destroyed. The tornado missed Western Kentucky University by 225 yards, but debris was thrown all over the campus including some impaled debris into buildings. The tornado went along 31W including doing significant damage to roof at Bobas lounge, a liquor store, and a smoke shop. This was estimated to be 110 to 120 mph winds, and tornado width decreased to 250 yards by Walgreens and Taco Bell. The tornado, appeared to be slightly elevated, doing mainly tree damage, power poles, and house roofing and siding along Magnolia Ave and Nutwood St. It crossed Lehman, went along Covington, with wind speeds mainly of 95 to 110 mph. The owner of 708 Nutwood said, your warning saved our lives, as our house was violently shaking, but we sought shelter and lived. Much of the tree damage was facing from the northeast to the northwest. The tornado paralleled Cemetery Rd doing roof and gutter damage along with power lines and tree damage. The tornadoes speed and winds increased along Cherokee Dr. with roofs removed and large healthy hardwood trees uprooted. The width increased to 300 yards and speeds to 105 mph with width of 225 yards. The narrow 175 yard funnel, hit the Indian Hills golf course, twisting, snapping, and topping numerous pines and cedars with winds speeds of 86 to 90 mph. The tornado then crossed the Barren River and increased in speed along Old Porter Pike to EF2, between 111 and 120 mph. Huge diameter hardwood trees were snapped and uprooted, including several very tall oak trees. There was also extensive roof damage to some well built homes. It weakened as it approached exit 28, doing EF1 damage of 90-95 mph to Hucks gas station and damaged a very tall Wendys sign. On the north side of 31 W, a fully loaded 18 wheeler facing west, was knocked over and was dragged 15 yards to a northwesterly directly. Winds were increased to EF2, of 115 mph. At the Corvette plant there was significant roof damage, with metal sheeting, insulation, HVAC units, and other debris thrown hundreds of yards downwind. Light poles in the parking lot were snapped, One of the security checkpoints at the Corvette plant was totally destroyed with large sections of the building being thrown several hundred yards, and weighing over 100 pounds, striking several vehicles. Winds were mainly in the 110 to 120 mph range. The tornado continued to parallel I 65, just west of the interstate. It struck several homes at Bristow Rd and Friendship Rd. Most of the damage was done to roofs siding and gutters and destroyed a well- built greenhouse. Numerous power poles and lines were down and the debris pattern was facing from southeasterly, all the way to northwesterly. There was some barn and tree damage near Kelly Road and the CSX railroad crossing. Winds were 85 to 90 mph and width of 200 yards. The tornado really increased across the TransPark at Exit 30. A few metal building structures at the peak intensity of the tornado sustained heavy damage. The middle building totally collapsed. Analysis showed that building was well constructed, but the shearing force from the intense tornado ripped the metal frame from the anchoring plates of the building. Analysis of the third building showed the tornado had weakened some at this point, down to EF2 levels. The WSR-8D radar showed a Tornadic Debris Signature downstream of this area, which was lofted to around 18 kft, right at the high end of EF3 of 165 mph. The tornado weakened further downstream as it caused roofing and siding damage to several structures and tree damage into southeast Edmonson County. Civil Air Patrol imagery helped identify the end point of this tornado.

After an in-depth radar analysis and on-the-ground surveying, the survey team found a separate tornado which first touched down as a thin skipping tornado just before the Bowling Green-Warren County Regional Airport. It damaged a storage building, and then became more ground based on the east side of the airport, damaging the roof of a well built hangar. The Bowling Green ASOS measured a 63 mph wind gust about a quarter mile away from the 100 yard wide tornado of 100 mph. The tornado increased in size to about 200 yards hitting the Hub apartments and townhouses. There was extensive damage to windows, as well as roofing. The garage units had the most structural roofing and side wall damage. Winds increased to 110 mph.

The tornado became more elevated hitting several trees, power lines, and there was some apartment roofing damage near the Barren River. The tornado crossed Interstate 65 near the 27 mile marker and was about 200 yards wide.

There was extensive tree damage and one barn was destroyed east of the interstate between Cumberland Trace Road and Porter Pike. Winds were between 90 and 100 mph, and then the tornado increased to EF2 120 mph striking the Corvette track and Motorsports Park. There was extensive damage to the main building and a series of garage and storage buildings had extensive structural damage to the individual roofs. Debris was thrown over half a mile to the east northeast. The tornado was 225 yards wide, and the survey team could see the main tornado damage about a half a mile away towards the Corvette plant on the other side of the interstate. NWS used drone technology to analyze the roofing structures for wind speed determinations.

The tornado weakened and paralleled Interstate 65 along McGinnis Road and Bristow Road. Most of the damage was tree damage. Trees were snapped, twisted, and uprooted facing from the northwest to the southeast direction. There was also some siding, gutter, and roofing damage. The tornado was between 100 and 150 yards wide and the wind speeds were around 90 to 95 mph before it lifted at the 29.2 mile marker.
