Two ways to read the storm

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 map of the storm over Iowa City, IA on Apr 14, 2026

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 0.5"

Only the radar-estimated size surface resolved for Apr 14, 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 Apr 14, 2026 sits in Iowa City's hail record

This was Iowa City's 6th recorded hail day, arriving 12 days after the Apr 2, 2026 storm. By severity it ranks 6th of the 10 storms we have logged here. Radar put the day's largest stone over Iowa City at 0.5" — radar-estimated size aloft.

The Apr 14, 2026 convective day was bigger than Iowa City: the same system put hail over 476 other tracked cities, 143 of them in Iowa. Nearest: Cedar Rapids (21 miles north, up to 1"); Marion (21 miles north, up to 1"); Fairfax (21 miles northwest, up to 0.75").

These maps are stills from Iowa City's Apr 14, 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.

Ground reports

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.

Below the severe threshold

What 0.5" hail means for Iowa City 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

$1.4M

Potential roof exposure — 113 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Other storms in Iowa City

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.
