Evidence / storm surfaces
How Clarkson saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Aug 12, 2026 — this storm produced no NEXRAD point detections over Clarkson, so there is one map to show, not two.
The storm in context
Where Aug 12, 2026 sits in Clarkson's hail record.
This was Clarkson's 5th recorded hail day, arriving 17 days after the Jul 26, 2026 storm. By severity it ranks 4th of the 5 storms we have logged here. Radar put the day's largest stone over Clarkson at 0.5" — radar-estimated size aloft.
The Aug 12, 2026 convective day was bigger than Clarkson: the same system put hail over 507 other tracked cities, 23 of them in Kentucky. Nearest: Leitchfield (5 miles west, up to 0.75"); Hudson (9 miles northwest, up to 0.75"); Bee Spring (15 miles south, up to 0.75").

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 Clarkson. 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.
Below the severe threshold
What 0.5" hail means for Clarkson roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$4.6M
Potential roof exposure — 384 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 384 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
August 2028
Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $81 on top of the $150 plan.
