| 2026-06-18 | WEST BUECHEL, KY | 81 | Severe | 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. |

The most recent quarter-size-or-larger hail storm recorded by NOAA within 25 miles of Louisville was on May 16, 2026. HailCheck refreshes from the NOAA Storm Events database daily, so newer events appear here as they are reported.
Louisville averages roughly 20 reported hail events per year within a 25-mile radius. Significant storms (quarter-size or larger) account for 92 of the 99 events recorded over the last five years.
The largest documented hail near Louisville in the last five years was egg-sized. Most Louisville-area hail falls in the marble-to-quarter range, with destructive storms (egg-size or larger) appearing roughly once every few years.
Most homeowners insurance policies in KY cover hail damage to roofs, siding, and gutters under the dwelling and other-structures coverage. Coverage typically requires the damage to be tied to a verifiable storm date — which is where the NOAA hail history above (and a HAAG-style test square validation) becomes important for the claim file.
Use the HailCheck address search to enter any street address in or near Louisville. HailCheck returns every NOAA hail event within a configurable radius, along with severity bands, dates, and storm narratives for Pro members.
If your property in or near Louisville took on hail during one of the storms above, the standard process for documenting damage is a 10×10 foot test square inspection. A HAAG-trained reviewer counts impact indicators — granule displacement, mat fractures, and bruising — within the marked square and produces a PASS or FAIL document for the claim file.
HailCheck offers a $99 photo-based HAAG-style test square validation. You submit photos from the field, our reviewer evaluates the impact indicators and cross-references the NOAA storm dates listed above, and a written PASS/FAIL determination is returned within one business day. We do not send anyone to the roof — the validation is built around the photos you submit.
Learn About $99 HAAG-Style ValidationLouisville sits east of the traditional hail alley, where hail events are less frequent than the central plains but tend to be associated with strong squall lines and tropical systems. Local roof systems are less commonly hardened for hail, which can mean even moderate impacts produce claim-worthy damage.
