Winifred, MT Hail Storm – June 2026

Winifred, Montana experienced a concluded hail-producing thunderstorm late afternoon on June 26, 2026, with peak hail measured at 2.09 inches and strong radar signatures across the local warning area.

What Happened

NWS issued a single severe thunderstorm warning for the Winifred area at 5:20 PM MDT on June 26, 2026 identifying hail signatures on dual-polarization radar. Radar-derived hail estimates included a 1.25-inch detection tied to that warning. The cell moved through the town and surrounding rural addresses in late afternoon and had ended by early evening. Storm intelligence for this event is based on dual-polarization radar detections and consolidated NWS alerting for the local warning area.

Damage Assessment

Radar-detected hail struck Winifred and adjacent rural properties. Hail this large frequently causes localized roof shingle fractures on low-slope asphalt roofs, denting to vehicle body panels, and broken glazing or skylights on exposed structures. Agricultural assets in the path — such as parked combines, irrigation control housings, and exposed high-value crops in field edges — were at elevated risk for impact damage. Metal roofing and exposed solar arrays are susceptible to pitting and microcracking that may not be immediately visible but can create long-term performance issues.

Field reports are limited; no spotter-verified widespread structural collapse or catastrophic loss was reported in available data. Inspections in Winifred should prioritize visible shingle loss, penetrations at roof flashings, dent patterns on vehicles, and glazing failures. Photographic documentation tied to precise locations will support any subsequent insurance or repair work.

What Contractors Should Know

Begin with a safety-first roof evaluation. Use fall protection and confirm structural soundness before walking roofs. Prioritize temporary tarping for roofs with open penetrations or missing shingles to prevent water intrusion. For residential appointments, collect representative photos of roof planes, eaves, gutters, and all vehicle panels before any repair work. Note and mark hail impact patterns rather than relying solely on random sampling.

On larger commercial or agricultural projects, inspect mechanical equipment, HVAC condensers, and solar modules for pitting or frame damage. Provide clients with a concise scope that separates immediate emergency repairs from full replacement estimates. Coordinate with adjusters using location-referenced photos and clear timelines for mitigation. Consider follow-up checks for microcracks on metal and solar surfaces that can degrade performance over time.
