Evidence / storm surfaces
How Dunn Center 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.
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.
Only the radar-estimated size surface resolved for Aug 30, 2026 — this storm produced no NEXRAD point detections over Dunn Center, so there is one map to show, not two.
The storm in context

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.

How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Oakdale — beyond Dunn Center itself.
Damage-capable hail signal
What 1" hail means for Dunn Center roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$7.7M
Potential roof exposure — 639 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 3 jobs
- Illustrative work
- ~$45K
Close just 0.5% of the 639 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
