Evidence / storm surfaces
How Herman 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 Apr 15, 2026 — this storm produced no NEXRAD point detections over Herman, so there is one map to show, not two.
The storm in context
Where Apr 15, 2026 sits in Herman's hail record.
This was Herman's 2nd recorded hail day, arriving 40 days after the Mar 6, 2026 storm. By severity it ranks 3rd of the 10 storms we have logged here. Radar put the day's largest stone over Herman at 1.75" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Herman: the same system put hail over 425 other tracked cities, 22 of them in Nebraska. Nearest: Tekamah (12 miles northeast, up to 1.75"); Hooper (15 miles southwest, up to 1"); Mondamin (17 miles northeast, up to 2").

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.
Hail reports
1 reportHigh damage potential
What 1.75" hail means for Herman 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 — 1,064 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 1,064 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
April 2028
Claims from this storm can typically be filed until around April 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 $223 on top of the $150 plan.
