Hail in Coin Jun 10, 2026
The radar-estimated size surface caught this storm, reaching 3.5" aloft. NEXRAD logged no point detections over Coin this day. At 3.5" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Coin saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar-estimated hail size
Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

Only the radar-estimated size surface resolved for Jun 10, 2026 — this storm produced no NEXRAD point detections over Coin, so there is one map to show, not two.
Where Jun 10, 2026 sits in Coin's hail record
This was Coin's 5th recorded hail day, arriving 23 days after the May 18, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Coin at 3.5" — radar-estimated size aloft.
The Jun 10, 2026 convective day was bigger than Coin: the same system put hail over 777 other tracked cities, 155 of them in Iowa. Nearest: Blanchard (7 miles south, up to 3.25"); Essex (7 miles north, up to 2.5"); Northboro (9 miles southwest, up to 3.5").
These maps are stills from Coin'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.

Reports came from Yorktown — beyond Coin itself.
What 3.5" hail means for Coin roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
What this storm is worth to a roofer
$13M

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.
