Evidence / storm surfaces
How Iowa City saw the hail — from two instruments
Jun 10, 2026 · Iowa City, IA
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 Surface resolved
Estimated size field 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.
Max size
0.75"
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.
The storm in context
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 9th of the 12 storms we have logged here. Radar put the day's largest stone over Iowa City at 0.75" — radar-estimated size aloft.
The Jun 10, 2026 convective day was bigger than Iowa City: the same system put hail over 777 other tracked cities, 155 of them in Iowa. Nearest: West Branch (8 miles northeast, up to 0.5"); Lone Tree (11 miles south, up to 0.5"); West Liberty (12 miles southeast, up to 0.75").
These maps are stills. In the app this date is one of 12 Iowa City 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.

Wind reports
1 reportNear the severe threshold
What 0.75" hail means for Iowa City roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm 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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 12, 2026.
