Sturgis, SD Hail Storm – August 2026

A severe hail storm tracked through Sturgis, South Dakota on August 18, 2026, producing 2.84-inch hail and fluctuating radar signatures in the early evening. The event produced multiple NWS alerts and several spotter-verified reports centered on the Sturgis metro.

What Happened

The storm developed into a line of strong convection across Meade County in the early evening and produced a sequence of NWS alerts between 8:03 PM and 9:23 PM CDT. At 8:03 PM CDT an NWS alert noted a radar-detected core consistent with 2.15-inch hail. A later radar-detected core at 8:34 PM CDT flagged 1.13-inch stones. At 9:05 PM CDT radar again identified a 1.5-inch core, and at 9:23 PM CDT the NWS issued a warning polygon without a radar hail detection.

Field observers in Sturgis submitted three spotter-verified reports clustered around 8:59–9:06 PM CDT that estimated hail near 1.5 inches in diameter. Those observers relayed their observations through a live media feed and a Slack channel. One of the spotters noted that the timing of their estimate was guided by radar imagery. Radar-detected hail cores earlier in the sequence were larger than the spotter estimates, indicating variance in hail size along the track through the metro area.

Damage Assessment

Submitted field reports for the Sturgis metro included size estimates but did not include detailed damage narratives. The three spotter-verified messages recorded roughly 1.5-inch stones and did not list roof failures or structural collapse in their submissions. Local NWS entries for this event remain limited to those spotter submissions and the NWS warning polygon history.

Radar reflectivity and dual-polarization returns show concentrated hailfall through central Sturgis and adjacent zones on the storm's path. Those radar cores produced inferred larger stones in isolated cores earlier in the sequence, which suggests potential for localized heavier impacts along the track even where spotters reported smaller stones. Contractors and claims teams working the area should treat locations directly under the radar cores as higher priority for inspection but document every finding to the street level.

No municipal damage assessments tied to this event were submitted with the spotter messages. Street-level photo documentation and time-stamped measurements will be required to establish roof and vehicle claims in Sturgis given the mixed radar and spotter evidence.

What Contractors Should Know

Inspect roofs in central Sturgis and along the storm track between 8:00 PM and 9:30 PM CDT on August 18. Start with properties nearest the radar cores identified in the early 8 PM alerts and then expand to the spotter locations recorded around 9:00 PM CDT. Prioritize asphalt shingle granular loss, bruising on metal panels, and dent patterns on vehicles that align with the observed hail orientation.
