Bunker, MO Hail Storm – August 2026

Bunker, MO – August 7, 2026: a storm in the early evening produced a peak hail size of 1.84 inches and moved through the Bunker metro area as a short-lived but intense hail-producing cell.

What Happened

The event unfolded in the early evening. NWS warnings issued two separate alert polygons tied to the same storm. At 6:40 PM CDT (23:40 UTC) the NWS warned of one-inch hail across a localized warning area. At 7:03 PM CDT (00:03 UTC) the NWS updated the warning area to report 1.25-inch hail. Post-event data indicates a peak measured hail size of 1.84 inches within the aggregated multi-zone report for Bunker. The storm is concluded.

Radar and warning timestamps place the most intense hail phase in the 6:30–7:15 PM CDT window. The warnings were labeled NWS warning only for confidence. Observation points and damage reports used in the multi-zone aggregate align with the late-afternoon to early-evening thunderstorm evolution across eastern Reynolds County.

Damage Assessment

Hail reaching 1.84 inches in diameter is larger than a golf ball. In Bunker this size is capable of cracking siding, denting unprotected metal, and puncturing some skylights. Asphalt shingle roofs can show bruising, granule loss, and localized shingle fractures at this size. Vehicles parked outdoors in the warning area are at elevated risk for dents and broken glass.

Damage exposure will vary by surface condition and installation age. Newly installed impact-rated roofing and high-profile metal panels will resist damage better than older asphalt shingles and vinyl siding. Soft metals such as aluminum on gutters and HVAC housing are vulnerable to denting even where roof damage is limited. Where intact vegetation or tree canopy existed along the storm path, foliage and fruit crops may show tearing or bruising consistent with marble- to golf-ball-sized impacts.

What Contractors Should Know

Prioritize a visual roof survey with full photographic documentation tied to property addresses inside the NWS warning area. Note the alert times 6:40 PM CDT and 7:03 PM CDT on inspection forms. Photograph gutters, HVAC covers, siding, skylights, and parked vehicles from multiple angles with a scale object when possible. Collect neighbor reports and any spotter observations to corroborate timing and hail concentration.

During initial assessment, mark locations of concentrated hail impact on a site diagram. For roofing, check for granule loss, fractured shingle tabs, and soft-spot depressions. For vehicles and metalwork, document dent patterns and measure maximum dent diameters where feasible. Provide an itemized scope of work tied to visible impact points and include recommended temporary protections if continued exposure to weather is possible.
