Evidence / storm surfaces
How Elgin saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for May 21, 2026 — this storm produced no NEXRAD point detections over Elgin, so there is one map to show, not two.
The storm in context
Where May 21, 2026 sits in Elgin's hail record.
This was Elgin's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 6th of the 10 storms we have logged here. Radar put the day's largest stone over Elgin at 1" — radar-estimated size aloft.
The May 21, 2026 convective day was bigger than Elgin: the same system put hail over 120 other tracked cities, 10 of them in North Dakota. Nearest: New Leipzig (7 miles west, up to 1"); Mott (17 miles west, up to 0.5"); Glen Ullin (28 miles north, up to 0.75").
These maps are stills. In the app this date is one of 10 Elgin 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 Elgin. 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.
Damage-capable hail signal
What 1" hail means for Elgin 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
$1.9M
Potential roof exposure — 155 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 155 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.
Names and phones for every home in the footprint: at most $33 on top of the $150 plan.
