Evidence / storm surfaces
How Sheyenne 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 Sep 3, 2026 — this storm produced no NEXRAD point detections over Sheyenne, so there is one map to show, not two.
The storm in context
Where Sep 3, 2026 sits in Sheyenne's hail record.
This was Sheyenne's 7th recorded hail day, arriving 49 days after the Jul 16, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Sheyenne at 1.5" — radar-estimated size aloft.
The Sep 3, 2026 convective day was bigger than Sheyenne: the same system put hail over 494 other tracked cities, 65 of them in North Dakota. Nearest: New Rockford (11 miles southeast, up to 1.5"); Cathay (12 miles southwest, up to 0.75"); Oberon (14 miles north, up to 1.5").
These maps are stills. In the app this date is one of 7 Sheyenne 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.
Nobody on the ground filed a report over Sheyenne for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
High damage potential
What 1.5" hail means for Sheyenne 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
$13M
Potential roof exposure — 1,051 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 5 jobs
- Illustrative work
- ~$75K
Close just 0.5% of the 1,051 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
September 2028
Claims from this storm can typically be filed until around September 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 $221 on top of the $150 plan.
