Hail in Reinbeck · Apr 14, 2026
The estimated-size surface reached 2.25" aloft; NEXRAD logged no point detections over Reinbeck that day. At 2.25" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Reinbeck saw the hail — from two instruments
Apr 14, 2026 · Reinbeck, 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
2.25"
Only the radar-estimated size surface resolved for Apr 14, 2026 — this storm produced no NEXRAD point detections over Reinbeck, so there is one map to show, not two.
The storm in context
Where Apr 14, 2026 sits in Reinbeck's hail record.
This was Reinbeck's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Reinbeck at 2.25" — radar-estimated size aloft.
The Apr 14, 2026 convective day was bigger than Reinbeck: the same system put hail over 476 other tracked cities, 143 of them in Iowa. Nearest: Grundy Center (5 miles west, up to 2.25"); Cedar Falls (7 miles north, up to 2.25"); Dike (9 miles northwest, up to 2.25").
These maps are stills. In the app this date is one of 7 Reinbeck 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.

Reports came from Dike — beyond Reinbeck itself.
Severe hail signal
What 2.25" hail means for Reinbeck 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.
3,293 homes × $12,000 avg. claim
Potential roof exposure
$40M
Potential roof exposure — 3,293 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 3,293 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.

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 8, 2026.
