Hail in Arthur Jun 17, 2026
The radar-estimated size surface caught this storm, reaching 3" aloft. NEXRAD logged no point detections over Arthur this day. At 3" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Arthur 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.

Only the radar-estimated size surface resolved for Jun 17, 2026 — this storm produced no NEXRAD point detections over Arthur, so there is one map to show, not two.
Where Jun 17, 2026 sits in Arthur's hail record
This was Arthur's 3rd recorded hail day, arriving 44 days after the May 4, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Arthur at 3" — radar-estimated size aloft.
The Jun 17, 2026 convective day was bigger than Arthur: the same system put hail over 294 other tracked cities, 134 of them in Illinois. Nearest: Arcola (5 miles east, up to 1.5"); Humboldt (7 miles south, up to 3"); Hammond (15 miles northwest, up to 2.25").
These maps are stills from Arthur's Jun 17, 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 3" hail means for Arthur 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.

Other storms in Arthur
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 2, 2026.
