How Cedar 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
0.5"
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Cedar, so there is one map to show, not two.
Where Apr 15, 2026 sits in Cedar's hail record
This was Cedar's 2nd recorded hail day, arriving 13 days after the Apr 2, 2026 storm. By severity it ranks 4th of the 5 storms we have logged here. Radar put the day's largest stone over Cedar at 0.5" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Cedar: the same system put hail over 425 other tracked cities, 127 of them in Iowa. Nearest: Fremont (5 miles east, up to 0.5"); Oskaloosa (9 miles northwest, up to 0.5"); Delta (12 miles northeast, up to 0.5").
These maps are stills from Cedar'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 0.5" hail means for Cedar roofs
Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
What this storm is worth to a roofer
$300K
Potential roof exposure — 25 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. 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.

Other storms in Cedar
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.
