Capitol, MT Hail Storm – June 2026

Capitol, MT saw a mid-afternoon hail event on June 1, 2026, producing a peak 1.71-inch hailstone and a brief radar-detected hail core. The storm concluded the same afternoon.

What Happened

A single NWS severe thunderstorm alert covered the Capitol metro on June 1. The alert issued at 3:23 PM MDT was based on dual-polarization NEXRAD hail detection reporting 1.33-inch hail in the warning area. Radar returns showed a compact, high-reflectivity core moving across the central metro in the mid-afternoon period. The warning polygon encompassed the primary path indicated by the radar sweep. No additional NWS alerts were issued for this cell after the 3:23 PM advisory. Field and surface reports in StormSnipe data were absent or not spotter-verified for this event. The storm was classified as concluded later that afternoon.

Damage Assessment

Hail of this size commonly produces denting to vehicle body panels and trim. Asphalt shingles with preexisting wear or loss of granules are at elevated risk for bruising and accelerated deterioration. Vinyl siding can show surface pockmarks and cosmetic scuffs. Skylights, solar panels, and exposed glazing are vulnerable to impact cracking when launched ice reaches hard angles. Landscaping losses are likely limited to defoliation and damage to tender plants and mulch rather than full canopy loss.

No spotter-verified damage reports are included in the incident record for Capitol on June 1. Insurers and adjusters should expect claimant patterns consistent with localized hail concentrations along the radar-indicated path and within the NWS warning area. Document vehicle dents, siding punctures, and roof membrane breaches with dated photographic evidence tied to the property address.

What Contractors Should Know

Inspect roofs for bruising, loose granules, and displaced shingles. Start with properties inside the NWS warning area and those nearest the radar-indicated core. Use high-resolution photos from a minimum of three angles and include a dated scale reference. Prioritize older asphalt roofs and low-slope sections where impact damage may lead to moisture intrusion. Record any immediate temporary repairs, such as tarps or seam sealing, and note materials used.

For exterior repairs, assess siding, gutters, and soft metals for dents and punctures that can trap moisture. Verify glazing and solar arrays for hairline cracks under polarized inspection. Provide homeowners with itemized estimates that separate cosmetic repairs from weatherproofing work. Coordinate with insurers on observed damage patterns and supply the NWS alert time and radar-detected hail size in estimates when requested.
