Survey Summary:

An NWS Storm Survey determined that a swath of straight line wind
damage occurred on the morning of June 18th. Most of the damage
occurred near the intersection of Poplar Level Road and Fern
Valley Road where a warehouse building roof was partially 
collapsed, a small building lost some roofing material, and a tree
was downed. The collapsed roof was pancaked downward with no 
debris lifted or thrown downstream. In addition, some insulation 
from the roof collapse was laying on the north side of the 
building, but not scattered downwind. The orientation of the tree 
damage was NW to SE, and consistent with TDWR velocity data 
showing a wind surge from WNW to ESE. Severe level wind gusts were
measured with this velocity surge upstream of the damage as well.

Sporadic tree damage also occurred to the ESE of the initial
damage point along Fegenbush Lane. Damage stopped just north of
Luhr Elementary School after a 1.25 mile swath of sporadic damage.

There had been a supercell thunderstorm that passed through the
area about 15 minutes prior, however the TSDF TDWR noted no low
level rotational couplet with the radar beam at 200-300 feet AGL.
Some mid level rotation was noted off of LVX, but at a higher 
overall height. Both radar data and damage patterns, as well as an
eyewitness account just after 5 AM all pointed more toward the
second straight line wind signature as the culprit.

A second area of damage was also surveyed in Fern Creek along
Volney Ct. Here, a large branch from a healthy large tree fell
into the corner bedroom of a home. Luckily, occupants inside 
where shaken, but not injured. It was determined that this damage
occurred just before Midnight, well before any thunderstorms
arrived. This damage was attributed to non-thunderstorm gradient
winds. Nearby observations at from the KLOU ASOS at Bowman Field
did measure a 44 MPH gust around the time the residents said the
damage occurred.

Survey Summary:
The National Weather Service conducted a storm survey in Meade
County, Kentucky for the storms that moved through the region
late Sunday night, June 21, 2026.  The nature of the damage was
consistent with straight line wind damage between 80 and 85 mph
in the Big Bend area of Meade county.

Damage was first observed on Big Bend Road where several trees were 
uprooted or snapped due to the high winds.  Paradise Bottom Road also 
had some tree damage.  Damaged areas north of the rock quarry near 
Big Bend Road had a similar direction facing to the north.  Tree damage 
continued along Battletown Road north of Battletown.  All damage south of
the rock quarry near Big Bend Road was facing to the south. 
These damage directions would indicate a thunderstorm downburst
likely occurred in the Big Bend area with winds spreading out in
different divergent directions, evident of a thunderstorm
downburst.  

The National Weather Service would like to thank Meade County Emergency 
Management for assistance with the survey, as well as the many helpful 
homeowners who called in and shared pictures of their damages.
