How Iowa City saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar-estimated hail size
Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Only the radar-estimated size surface resolved for Jun 10, 2026 — this storm produced no NEXRAD point detections over Iowa City, so there is one map to show, not two.
Where Jun 10, 2026 sits in Iowa City's hail record
This was Iowa City's 7th recorded hail day, arriving 57 days after the Apr 14, 2026 storm. By severity it ranks 7th of the 10 storms we have logged here. Radar put the day's largest stone over Iowa City at 0.75" — radar-estimated size aloft.

These maps are stills from Iowa City's Jun 10, 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.
Wind reports
1 reportWhat 0.75" hail means for Iowa City roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.
What this storm is worth to a roofer

ground reports
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.
