What Happened

A single severe thunderstorm moved through the Hardin area in the early evening on July 15. The National Weather Service issued one warning at 6:07 PM MDT that referenced radar-detected hail up to 2.15 inches within the warning area. Dual-polarization NEXRAD data indicated concentrated hail core returns along the storm's track through the immediate Hardin metro and nearby rural addresses. The event was brief and isolated; no additional NWS alerts were issued for the same cell after the 6:07 PM warning. Storm status is concluded.

Damage Assessment

Hail of this diameter can produce clear, measurable impact on common building materials and vehicles in Hardin and surrounding properties inside the NWS warning area. On roofs, impacts can split granules on asphalt shingles, bruise or dent metal panels, and crack vulnerable roof-mounted equipment. On vehicles, expect denting to sheet metal and possible cracking or shattering of glass where hail struck directly. Exterior siding, skylights, and soft-wood trim are also at heightened risk of punctures and fractures when struck by hail this size.

Agricultural exposures near Hardin should be inspected for standing crop defoliation and bruising to fruit and high-value plants. Detached items and unshielded equipment are likely to show direct impact damage and should be checked before being placed back into service. Where leaks or compromised seals are found, address them promptly to limit secondary water damage.

What Contractors Should Know

Prioritize a methodical roof inspection workflow. Start with a perimeter walk to document visible shingle loss, dented flashing, and displaced fasteners. Photograph damage with a scale reference and note GPS or address for each observation inside the NWS warning area. For metal roofing and siding, record dent counts per panel and check for through-paint penetration. For vehicles and glazing, document broken panes and shattered seals separately from body dents to support insurance claims.

When scheduling repairs, plan for temporary mitigation first to stop active water entry. Use industry-standard tarping where necessary, then follow with a measured repair estimate for materials and labor. Coordinate with property owners and insurers around prioritized repairs for roofing and structural openings. Maintain safety protocols for post-storm work in storm-affected zones and confirm local permitting or disposal requirements for damaged materials.
