Evidence / storm surfaces

How Custer saw the hail — from two instruments

Jun 6, 2026 · Custer, SD

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-signature map of the hail storm over Custer, SD on Jun 6, 2026 Radar signature field

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.

The storm in context

Where Jun 6, 2026 sits in Custer's hail record.

This was Custer's 4th recorded hail day, arriving 4 days after the Jun 2, 2026 storm. By severity it ranks 9th of the 20 storms we have logged here. Radar put the day's largest stone over Custer at 1.75" — the largest NEXRAD radar signature.

The Jun 6, 2026 convective day was bigger than Custer: the same system put hail over 447 other tracked cities, 7 of them in South Dakota. Nearest: Hill City (18 miles north, up to 1"); Deadwood (26 miles north, up to 1"); Rapid City (28 miles northeast, up to 0.5").

These maps are stills. In the app this date is one of 20 Custer 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.

Ground reports

What people on the ground reported

No reports filed with the NWS

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.

Nobody on the ground filed a report over Custer for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

High damage potential

What 1.75" hail means for Custer roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Claim window

June 2028

Claims from this storm can typically be filed until around June 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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 Sep 14, 2026.
