Evidence / storm surfaces
How Cope saw the hail — from two instruments
May 21, 2026 · Cope, CO
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.
Radar-estimated hail size Surface resolved
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.
Max size
1.75"
Only the radar-estimated size surface resolved for May 21, 2026 — this storm produced no NEXRAD point detections over Cope, so there is one map to show, not two.
The storm in context
Where May 21, 2026 sits in Cope's hail record.
This was Cope's 2nd recorded hail day, arriving 25 days after the Apr 26, 2026 storm. By severity it ranks 2nd of the 9 storms we have logged here. Radar put the day's largest stone over Cope at 1.75" — radar-estimated size aloft.
The May 21, 2026 convective day was bigger than Cope: the same system put hail over 120 other tracked cities, 20 of them in Colorado. Nearest: Joes (5 miles east, up to 0.5"); Flagler (15 miles southwest, up to 2.25"); Vona (17 miles south, up to 1.25").
These maps are stills. In the app this date is one of 9 Cope 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.

High damage potential
What 1.75" hail means for Cope 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.
387 homes × $12,000 avg. claim
Potential roof exposure
$4.6M
Potential roof exposure — 387 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 387 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
May 2028
Claims from this storm can typically be filed until around May 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 20, 2026.
