Belvidere, SD Hail Storm – July 2026

Belvidere, SD experienced a concluded hail event on July 29, 2026, producing up to 1.69-inch hail and prompting one NWS severe thunderstorm warning. The storm moved through the metro in the late evening and produced a concentrated hail swath.

What Happened

The primary storm crossed Belvidere in the late evening hours of July 29. The National Weather Service issued a severe thunderstorm warning at 10:01 PM CDT for the area; the warning did not include a hail size estimate and was issued as a warning-only alert. Dual-polarization radar returns and subsequent local reports indicate a discrete hail swath passed through the town. The event was short-lived and concluded within a single storm pulse rather than a long-lived convective system.

Radar-detected hail signatures aligned with the warning polygon issued by the NWS. Field reports and automated detections were used to establish the peak hail measurement recorded for the event. No additional NWS alerts were issued for the metro after the 10:01 PM CDT warning, and the storm was classified as concluded once radar reflectivity decreased below hail-producing thresholds.

Damage Assessment

Localized impacts are likely along the storm path through Belvidere. Vehicle body panels in the neighborhoods inside the warning polygon are at elevated risk for dents and chipped paint. Asphalt roofing may show granule loss and bruising on exposed slopes. Skylights, solar panels, and soft roofing membranes are vulnerable to puncture where hail accumulated on the ground.

Public infrastructure risks include cracked street signs, damaged building awnings, and compromised rooftop equipment in commercial properties inside the warned area. If any roof coverings show visible perforations or large areas of granule displacement, follow standard emergency weather repairs to prevent water intrusion until full repairs can be scheduled.

What Contractors Should Know

Prioritize safety and documentation on arrival. Confirm utilities are de-energized where rooftop work is required. Photograph overall property context, individual damage items, and the surrounding yards and streets for claims support. Note the local time of inspection and reference the NWS warning issued at 10:01 PM CDT when logging event timing.

Begin with triage-level inspections: vehicles first for obvious hail dents, then roofs for granule loss and impact patterns, then skylights and solar arrays for perforations. Temporary tarps are appropriate only where immediate water intrusion is present. Schedule full shingle-level or panel-level repairs after a thorough assessment. Retain loose hail samples and label them with location and time to support any supplemental field reports.
