Evidence / storm surfaces
How Louisville saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Only the NEXRAD radar-signature surface resolved for Jun 30, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Jun 30, 2026 sits in Louisville's hail record.
This was Louisville's 2nd recorded hail day, arriving 38 days after the May 23, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Louisville at 0.75" — the largest NEXRAD radar signature.
The Jun 30, 2026 convective day was bigger than Louisville: the same system put hail over 720 other tracked cities, 35 of them in Alabama. Nearest: Ariton (9 miles southwest, up to 1.75"); Ozark (15 miles southwest, up to 2.25"); New Brockton (27 miles southwest, up to 1").

Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
For this storm over Louisville, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Near the severe threshold
What 0.75" hail means for Louisville roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$504K
Potential roof exposure — 42 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
June 2028
Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
