Evidence / storm surfaces
How Louisville saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
The storm in context
Where Jul 26, 2026 sits in Louisville's hail record.
This was Louisville's 9th recorded hail day, arriving 23 days after the Jul 3, 2026 storm. By severity it ranks 6th of the 9 storms we have logged here. Radar put the day's largest stone over Louisville at 0.75" — radar-estimated size aloft.
The Jul 26, 2026 convective day was bigger than Louisville: the same system put hail over 351 other tracked cities, 58 of them in Illinois. Nearest: Flora (7 miles south, up to 0.75"); Farina (8 miles west, up to 1.75"); Ingraham (13 miles east, up to 0.75").
These maps are stills. In the app this date is one of 9 Louisville storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
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.
The National Weather Service logged no spotter reports for this storm over Louisville. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
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
$18M
Potential roof exposure — 1,517 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 8 jobs
- Illustrative work
- ~$120K
Close just 0.5% of the 1,517 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
July 2028
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
