Bunker, MO Hail Storm – August 2026

Bunker, MO — August 7, 2026. A severe thunderstorm is tracking through the area in the early evening, producing hail up to 1.84 inches and continuing to develop.

What Happened

The storm moved into the Bunker area in the late afternoon and intensified into early evening. The National Weather Service issued two hail warnings for the event: a 1.00-inch hail warning at 6:40 PM CDT (23:40 UTC) and a 1.25-inch hail warning at 7:03 PM CDT (00:03 UTC). Both alerts are noted as NWS warning only. Observations are still being collected and the storm is active and continuing to produce hail as it tracks through local warning areas.

Radar returns currently show strong reflectivity cores along the storm path. No spotter-verified damage reports have been published to the NWS at this time. Local conditions may change rapidly while the storm remains active; crews in the field should expect ongoing hail production within the advisory polygons issued by the NWS.

Damage Assessment

Hail sizes reported in the warnings — roughly quarter to slightly larger than quarter-to-golf-ball range — typically cause cosmetic and functional damage to exposed surfaces. On residences, expect possible bruising and granule loss on asphalt shingles, dents to metal gutters and aluminum siding, and cracked exterior light fixtures. For roofing, multiple impacts concentrated on the same plane increase the likelihood of accelerated wear and shingle failure.

For vehicles parked outdoors, hail in the reported size range commonly produces dents to body panels, chipped paint, and broken side mirrors or windshields when impacts are concentrated. Agricultural structures and unprotected equipment are vulnerable to punctures and denting. Areas within the NWS warning area should be inspected for localized roof granular loss and damaged vehicle panels once conditions permit.

What Contractors Should Know

Safety first. The storm remains active in the Bunker warning area, so confirm all crews are clear of exposed work and not operating on elevated surfaces until storms pass and conditions are declared safe. Use the NWS warning area to guide route planning and avoid placing crews inside polygons where hail production is ongoing. Prioritize crew accountability and weather briefings before re-entering damaged zones.

For field assessment, document damage with time-stamped photos and GPS locations. Start with high-priority inspections: roofs with visible granular loss, vehicles parked under trees or open lots, and commercial metal roofing. For roofing, look for clustered impact patterns and broken tabs. Temporary tarps and fasteners should be deployed only after a qualified assessment confirms immediate exposure. Keep repair estimates conservative until material-level inspections are completed.

Precise radar-derived hail tracks and the paid Strike Map product provide exact hail track and damage zone data for mapping inspection routes and documenting impact lines.
