Rapid City, SD Hail Storm – July 2025

What Happened

A severe hail storm crossed the Rapid City, SD metro on July 1, 2025, with peak hail reports of 1.75 inches and multiple spotter-confirmed hail observations through the late afternoon and evening. The event concluded after a long sequence of warnings, radar detections, and ground reports across the metro area.

The first high-end radar-derived hail alert came at 4:32 PM CDT with 1.75-inch hail confidence. Another 1.5-inch alert followed at 4:55 PM CDT, then a second 1.75-inch alert at 5:23 PM CDT. Spotters reported nickel to quarter size hail at 5:27 PM CDT, with two separate reports at the same time placing the hail near 1 inch. A later spotter report at 7:02 PM CDT described dime to quarter hail, also around 1 inch.

Radar and field confidence stayed elevated into the evening. Alerts at 6:13 PM CDT and 6:19 PM CDT again reached 1.75 inches with radar and spotter verification. Additional 1.5-inch alerts were issued at 6:43 PM CDT, 7:13 PM CDT, 7:43 PM CDT, and 7:46 PM CDT. A later 1.75-inch radar alert came at 7:33 PM CDT. The final two alerts, at 8:39 PM CDT and 9:09 PM CDT, showed 1.25-inch hail confidence as the storm weakened.

The storm produced a broad warning area across the Rapid City metro, with hail reports clustering through the middle and later portions of the event. The repeated radar signals and spotter observations pointed to a storm that maintained hail production across several hours rather than a brief pulse.

Damage Assessment

The field reports show a storm that reached the ground with enough intensity to support spotter-confirmed hail near 1 inch in multiple locations. Nickel to quarter size hail was reported twice at 5:27 PM CDT, and dime to quarter hail was reported again at 7:02 PM CDT. Those reports place the heaviest surface impact in the quarter-size range for the observed ground truth.

The radar alerts were stronger than the spotter hail size in some intervals, which is common in a storm with changing hail cores. The 1.75-inch radar confidence at 4:32 PM CDT, 5:23 PM CDT, 6:13 PM CDT, 6:19 PM CDT, and 7:33 PM CDT shows a storm capable of producing larger stones aloft even where field reports documented smaller hail at the surface. The later 1.25-inch alerts at 8:39 PM CDT and 9:09 PM CDT show the storm easing down while still carrying hail potential.

For surface impact, the reports point to repeated hail fall across the metro rather than a single isolated strike point. That pattern matters for roof, siding, gutter, and vehicle checks across exposed properties in the warning area, especially where hail fell in more than one round. A contractor should expect scattered but widespread cosmetic claims, with the most visible issues likely on soft metals, vehicle finishes, and older roof materials that took multiple passes.
