Two ways to read the storm

How Hill 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 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 Jun 21, 2026 — this storm produced no NEXRAD point detections over Hill City, so there is one map to show, not two.

The storm in context

Where Jun 21, 2026 sits in Hill City's hail record

This was Hill City's 5th recorded hail day, arriving 15 days after the Jun 6, 2026 storm. By severity it ranks 11th of the 12 storms we have logged here. Radar put the day's largest stone over Hill City at 0.5" — radar-estimated size aloft.

The Jun 21, 2026 convective day was bigger than Hill City: the same system put hail over 415 other tracked cities, 2 of them in South Dakota. Nearest: Pringle (32 miles south, up to 0.5"); Hot Springs (52 miles south, up to 0.5"); Chadron (92 miles south, up to 1.5").

These maps are stills from Hill City's Jun 21, 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.

No ground reports were filed with the National Weather Service for this storm over Hill City. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Below the severe threshold

What 0.5" hail means for Hill 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

$24K

Potential roof exposure — 2 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.

Other storms in Hill 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.
