Both radar surfaces caught this storm: NEXRAD logged 2 hail signatures up to 3.75", and the radar-estimated size reached 2.25" aloft. At 3.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

Independent storm reports filed with the NWS.
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.
NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
This was Ideal's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Ideal at 3.75" — the largest NEXRAD radar signature.
The Jun 3, 2026 convective day was bigger than Ideal: the same system put hail over 274 other tracked cities, 69 of them in South Dakota. Nearest: Hamill (14 miles southeast, up to 2.5"); Presho (23 miles northwest, up to 3"); Gregory (28 miles east, up to 2.5").
These maps are stills from Ideal's Jun 3, 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.
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.

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.
