Two ways to read the storm

How Rapid City 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.

NEXRAD radar-signature map of the hail storm over Rapid City, SD on Jul 30, 2026 — 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.

Only the NEXRAD radar-signature surface resolved for Jul 30, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.

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 Rapid 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.

Near the severe threshold

What 0.75" hail means for Rapid City roofs

Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.
