Storms and tornadoes of April 5, 2023

Tornadoes:

The National Weather Service in Louisville confirmed an EF-1
tornado in the Pleasure Ridge Park area of western Jefferson
County. The tornado touched down just east of Dixie Highway (U.S.
Route 31W) at the edge of the railroad tracks, just south of
Blanton Lane and just east of Lowe`s home improvement store. The
tornado did extensive tree damage, ranging from uprooted large
root balls to twisted and snapped trees to a few large branches
impaled into the ground.

Trees were facing from a north-northeasterly direction all the way
to an east-southeasterly direction. Several trees crushed cars
along Mills Drive. Numerous power lines were down, and many homes
had shingle, gutter, and fascia damage. Several garages and
outbuildings sustained roof and siding damage all along Blanton Lane.
Drone photography showed extensive tree damage with several uprooted
larger trees. One outbuilding near Oak Valley Drive had its roof
and siding blown 125 yards. Wind speeds in this part of the tornado
were between 90 and 100 mph.

The tornado snapped several hardwood trees along Rosemary Lane, along
with sporadic roofing damage to homes. At 7616 Rosemary Lane, a western
facing window was somehow sucked out and thrown back to the northwest,
some 30 yards away. The homeowner recounted a huge pressure change
when the tornado hit.

The tornado intensified on Brooklawn Drive, towards the back
portion of the apartments.  One entire roofing section of an
apartment complex was picked up and thrown and twisted into the
trees on the hill behind. This was the most extensive and drastic
amount of damage in the area. In the parking lot east of that
building, insulation and building fascia surrounded vehicles.

The furthest east apartment building had half of the south-facing
fascia and brick removed. In addition, the back side (eastern
portion) of the apartment building had a large portion of the
siding and fascia removed.  All of the roof material, siding, and
insulation was thrown and splattered into the trees. Drone
photography showed it scattered about from a northeasterly to a
southeasterly facing direction. Wind speeds in the Brooklawn
apartment complex were 110 mph, a high-end EF-1 rating.

The tornado lifted on top of the hill just behind the last apartment
building and before it reached Renwood Boulevard.

The National Weather Service would like to thank the Pleasure Ridge 
Park fire department for all their assistance with the survey.

The National Weather Service in Louisville conducted a storm
assessment survey across the Watterson Park neighborhood in
Louisville. This is the area just south of the intersection of
Newburg Road and Interstate 264 (Watterson Expressway). There
were two tornadoes in this area separated by a clear and distinct
break of about 200 yards.

The first tornado started just north of the main Post Office
distribution center. The tornado touched down just northwest of the
intersection of Colonel Sanders Drive and Gardiner Lane. Trees were
snapped and uprooted in this area before the tornado struck the roof
of Yum! Brands headquarters. The northeast side of the well-constructed
building had a substantial portion of parapet wall removed and the
brick wall was partially pushed inwards. Wind speeds in this area were
estimated to be 95 mph.

The tornado continued to produce tree damage, including snapped,
twisted, and uprooted trees. Wind speeds were between 87 and 90 mph in
this area.  The tornado lifted by Robards Lane just south of Gardiner
Lane.

The National Weather Service in Louisville conducted a storm
assessment survey across the Watterson Park neighborhood in
Louisville. This is the area just south of the intersection of
Newburg Road and Interstate 264 (Watterson Expressway). There
were two tornadoes in this area separated by a clear and distinct
break of about 200 yards.

The second tornado touched down near the intersection of Annshire
Avenue and Vineyard Drive. There was some sporadic tree damage
just south of the US Post Office on Gardiner Lane, ranging from
80 to 85 mph. The twister quickly increased in strength to an EF-1
tornado of 90 mph, hitting the the DashMart warehouse. The western
wall of the warehouse was blown out with debris scattered downwind
from the northeast to southeast direction. There was tree damage
further east including some debarking of older softwood trees. The
north side of a mini storage facility had significant damage, and
part of the Kroger distribution center had some substantial wall damage.

The tornado next crossed Gardiner Lane and hit the Big Brothers Big
Sisters building, knocking down a statue and causing minor roof
damage. There was more roof damage at the Louisville Metro
Housing Authority off of Bishop Lane. There was wood fence damage
between the Speedway and Little People Academy off of Classified
Place. The damage east of Gardiner Lane was between 85 and
90 mph.

The tornado crossed Bishop Lane before causing roof
damage to the Jefferson County Public Schools` Van Hoose Center.
Wind speeds were estimated to between 80 and 85 mph.

This information remains preliminary and could be adjusted pending
additional surveys east of Newburg Road.

The National Weather Service conducted a storm survey of a severe
thunderstorm that caused damage along US Highway 60 (Owensboro
Highway). Damage was first observed along Hogwallow Lane where
tractor trailers were blown over along the roadway. Snapped and
uprooted tree damage was observed at several homes headed 
eastwardalong US Highway 60. The most extensive damage was 
observed along Tiptop road, where a camper was blown over along
with extensive tree damage. A garage outbuilding also had several
panels blownoff in the northeast direction. Tree damage was also
observed along Robbins Drive and Finch Court, including complete
destruction of several car ports. All damage was in the
northeasterly direction and appeared to become more widespread
toward the end of the damage path, which is more indicative of
straight line wind damage. Estimated max wind speeds along the
path from damage ranged between 80 mph and 100 mph.

The National Weather Service would like to thank Meade County
Emergency Management for the damage reports and assistance with
the survey, as well as all the helpful homeowners that provided
reports near Robbins Drive.

The National Weather Service Louisville confirmed an EF1 tornado
in Eastern Perry County Indiana, near Leopold, from severe storms
on Wednesday afternoon, April 5. The tornado touched down in a
hilly forested area, along Leopold Oriole Road, 0.2 miles north
of the Leopold town square. The twister started off as an EF0 80
mph in the forested area with a few snapped and uprooted trees.
The tornado rapidly increased to a 95 mph EF1 striking a very well
built 45 by 125 barn with extra hurricane clips, nails and bolts.
The foundation of the barn through the roof bracing was one of the
best new built barns this survey team has ever seen.

A large portion of the roof was thrown over 100 yards to the north
northeast to a easterly direction. There were numerous boards impaled
into the ground and some of the metal sheeting was thrown 200 yards,
wrapping around a large maple tree. NWS drone footage showed a few
more pieces of the roof were thrown into the neighbor`s pond, which
is about 350 yards away. Residents at the home felt their house shake
for about 15 seconds and their ears were popping.

Adjacent to the barn was a tractor tire that was moved 25 yards to the
northwest with no noticeable skid marks with the tire. The foundation
of the barn was pulled northeastward slightly, and a large pick up
trailer fully loaded with supplies in the barn moved about 6 inches.

The drone showed a large area of snapped and uprooted trees just
northeast of the home in a forested area. The drone showed no damage
beyond that tree damage across a farmers field.

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0 Weak 65-85 mph	EF1 Moderate 86-110 mph	EF2 Significant 111-135 mph	EF3 Severe 136-165 mph	EF4 Extreme 166-200 mph	EF5 Catastrophic 200+ mph

Wind

The intense line of thunderstorms produced scattered straight-line wind damage in addition to the tornadoes. Straight-line winds of more than 80 mph occurred in localized areas. 

The National Weather Service in Louisville conducted a storm
assessment survey from the Bashford Manor area near Buechel up
to the Bluegrass Industrial Park near the intersection of
Hurstbourne Parkway and Interstate 64. All of the damage surveyed
in these areas was straight-line wind damage, with maximum wind
speeds estimated between 75 and 85 mph.

Bashford Manor area...

There was extensive tree damage just south of the intersection of
Bardstown Road (U.S. Route 150) and the Watterson Expressway
(Interstate 264). Several large trees were uprooted, including
oak, pine, and maple trees. Some of the trees and larger limbs
fell on homes, garages, and outbuildings, causing significant
property damage. Most of the damage in this area was consistent
with wind speeds between 65 and 75 mph, with trees falling in a
unidirectional manner toward the northeast.

The most substantial damage in this area occurred between Donard
Park Avenue and Bardstown Road along Bashford Manor Lane, where
two very large oak trees had been uprooted. This is consistent
with wind speeds of 80 mph. However, there was sparse damage to
smaller trees in this area (such as Bradford pears), suggesting
that wind speeds were much stronger slightly off the ground.

Bluegrass Industrial Park...

There was damage to a large warehouse at 1800 Cargo Court
consistent with wind speeds between 75 and 85 mph. An aerial survey
was attempted on Wednesday night, but had to be postponed until Friday
due to lingering rain showers in the area. The aerial survey showed
significant damage to the northwest portion of the roof of the
warehouse, with all of the debris being pushed northeastward,
consistent with severe straight-line winds. The aerial survey
continued from a Marriott hotel up to Interstate 64, revealing
little additional damage outside of a few downed small tree limbs.

Tractor trailers flipped by damaging straight-line winds estimated at 90 mph along US 60 in Meade County, KY	Significant roof damage to a commercial building in Corydon, IN	Multiple large trees snapped or uprooted by straight-line winds at Hayswood Nature Reserve in Corydon	Roof damage to a business in Louisville
