Evidence / storm surfaces
How Perry 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 21, 2026 — this storm produced no NEXRAD point detections over Perry, so there is one map to show, not two.
The storm in context
Where Aug 21, 2026 sits in Perry's hail record.
This was Perry's 11th recorded hail day, arriving 48 days after the Jul 4, 2026 storm. By severity it ranks 7th of the 11 storms we have logged here. Radar put the day's largest stone over Perry at 1.5" — radar-estimated size aloft.
The Aug 21, 2026 convective day was bigger than Perry: the same system put hail over 659 other tracked cities, 9 of them in Oklahoma. Nearest: Stillwater (9 miles southeast, up to 1.75"); Ponca City (21 miles north, up to 0.5"); Chandler (38 miles southeast, up to 0.5").
These maps are stills. In the app this date is one of 11 Perry 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.
No ground reports were filed with the National Weather Service for this storm over Perry. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
High damage potential
What 1.5" hail means for Perry 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
$504K
Potential roof exposure — 42 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.
