Edgemont, SD Hail Storm – May 2026

Edgemont, SD experienced hail-producing thunderstorms on May 30, 2026, with radar detections peaking at 2.54 inches. The storm progressed from mid‑afternoon into the early evening and produced a multi-alert radar hail track across the town.

What Happened

NWS warning areas were issued eight times as the line moved through the Edgemont metro. Early radar detections around mid‑afternoon showed hail signatures near 1.25 inches. The sequence escalated through multiple dual‑polarization radar detections and one spotter-verified report. A field observer verified 2.26-inch hail at 4:12 PM CDT. Subsequent dual‑polarization radar detections recorded large returns in the late afternoon and into early evening, including significant radar-detected values at 5:38 PM CDT and 6:13 PM CDT. The alerts were issued as radar-detected hail signals intensified and shifted across town. The event is concluded.

Damage Assessment

Recorded hail detections during the event covered a range from roughly one inch to just over two and a half inches. The 4:12 PM CDT spotter-verified 2.26-inch report indicates that at least one location in Edgemont experienced hail capable of producing severe surface impact. Hail in the roughly 1.0–1.5 inch range typically causes cosmetic damage to paint and minor dents to vehicles and metal surfaces. Hail above 2.0 inches frequently tears asphalt shingles, breaks skylights, and causes extensive vehicle panel damage. Roof coverings exposed in the warning area during late afternoon likely experienced shingle loss and punctures where the larger detections passed.

Field reports and radar locations that cluster in specific neighborhoods should be prioritized for on-site assessment. Use the timing of the larger detections to cross-reference when inspecting roofs, vehicles, and exterior building systems.

What Contractors Should Know

Start with a safety-first roof inspection. Document existing conditions before making repairs. Capture multiple photographs of shingle edges, vents, gutters, and any punctures. Where the 4:12 PM CDT spotter verification occurred, expect concentrated impact patterns and consider full-system inspections rather than spot repairs. For vehicles, inventory hail dents with close-up photos and reference the local detection times to validate claim windows.

For triage, prioritize tarping open roof breaches and securing loose siding to prevent secondary water damage. Coordinate measurement of hail size on-site when fragments remain; record approximate diameter next to a ruler in photos. Provide time-stamped inspection reports tied to the event timeline. Communicate clearly with property owners about likely repair scopes and the need for follow-up inspections where radar detections clustered.
