Evidence / storm surfaces
How Rapid City saw the hail — from two instruments
Jun 22, 2026 · Rapid City, SD
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 Surface resolved
Estimated size field 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.
Max size
1"
Only the radar-estimated size surface resolved for Jun 22, 2026 — this storm produced no NEXRAD point detections over Rapid City, so there is one map to show, not two.
The storm in context
Where Jun 22, 2026 sits in Rapid City's hail record.
This was Rapid City's 8th recorded hail day, arriving 15 days after the Jun 7, 2026 storm. By severity it ranks 7th of the 26 storms we have logged here. Radar put the day's largest stone over Rapid City at 1" — radar-estimated size aloft.
The Jun 22, 2026 convective day was bigger than Rapid City: the same system put hail over 258 other tracked cities, 14 of them in South Dakota. Nearest: Deadwood (5 miles west, up to 2.25"); Black Hawk (9 miles northeast, up to 1.25"); Custer (28 miles southwest, up to 1.25").

Damage-capable hail signal
What 1" hail means for Rapid City roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

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 7, 2026.
