Evidence / storm surfaces
How Oldham 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 24, 2026 — this storm produced no NEXRAD point detections over Oldham, so there is one map to show, not two.
The storm in context
Where Aug 24, 2026 sits in Oldham's hail record.
This was Oldham's 5th recorded hail day, arriving 18 days after the Aug 6, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Oldham at 1.75" — radar-estimated size aloft.

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 Oldham. 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.
High damage potential
What 1.75" hail means for Oldham roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$12M
Potential roof exposure — 1,021 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

- 5 jobs
- Illustrative work
- ~$75K
Close just 0.5% of the 1,021 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
