Evidence / storm surfaces
How Chadron saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
The storm in context
Where Aug 27, 2026 sits in Chadron's hail record.
This was Chadron's 17th recorded hail day, arriving 4 days after the Aug 23, 2026 storm. By severity it ranks 1st of the 18 storms we have logged here. Radar put the day's largest stone over Chadron at 2.75" — radar-estimated size aloft.
The Aug 27, 2026 convective day was bigger than Chadron: the same system put hail over 365 other tracked cities, 41 of them in Nebraska. Nearest: Oelrichs (25 miles north, up to 2.75"); Smithwick (29 miles north, up to 2.75"); Hemingford (35 miles south, up to 1.25").
These maps are stills. In the app this date is one of 18 Chadron 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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked south at roughly 20 mph, based on the timing of ground reports.
Hail was reported over 57 minutes, from to .
Reports came from Chadron State Par — beyond Chadron itself.
Severe hail signal
What 2.75" hail means for Chadron roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$49M
Potential roof exposure — 4,111 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 21 jobs
- Illustrative work
- ~$315K
Close just 0.5% of the 4,111 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 $863 on top of the $150 plan.
