How Winterset saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Max size
1.5"
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Winterset, so there is one map to show, not two.
Where Apr 15, 2026 sits in Winterset's hail record
This was Winterset's 2nd recorded hail day, arriving 1 day after the Apr 14, 2026 storm. By severity it ranks 1st of the 13 storms we have logged here. Radar put the day's largest stone over Winterset at 1.5" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Winterset: the same system put hail over 425 other tracked cities, 127 of them in Iowa. Nearest: Earlham (15 miles north, up to 0.5"); Greenfield (21 miles west, up to 0.5"); New Virginia (22 miles east, up to 0.5").
These maps are stills from Winterset's Apr 15, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

What 1.5" hail means for Winterset roofs
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
What this storm is worth to a roofer
$49M
Potential roof exposure — 4,083 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
