Evidence / storm surfaces
How Montour saw the hail — from two instruments
Apr 15, 2026 · Montour, IA
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"
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Montour, so there is one map to show, not two.
The storm in context
Where Apr 15, 2026 sits in Montour's hail record.
This was Montour's 2nd recorded hail day, arriving 16 days after the Mar 30, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Montour at 1" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Montour: the same system put hail over 425 other tracked cities, 127 of them in Iowa. Nearest: Toledo (6 miles northeast, up to 0.75"); Garwin (7 miles north, up to 0.75"); Gilman (9 miles southwest, up to 1").
These maps are stills. In the app this date is one of 5 Montour 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.

Damage-capable hail signal
What 1" hail means for Montour 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.
1,284 homes × $12,000 avg. claim
Potential roof exposure
$15M
Potential roof exposure — 1,284 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 6 jobs
- Illustrative work
- ~$90K
Close just 0.5% of the 1,284 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 $270 on top of the $150 plan.

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 3, 2026.
