Mosby, MT experienced a concluded hail event on July 2, 2026 producing 2.81-inch hail and multiple radar-detected and NWS-warning reports in the early evening.

What Happened

The storm moved through Mosby in the early evening and generated a sequence of six NWS alerts and radar detections between 7:09 PM MDT and 9:40 PM MDT.

• July 2 · 7:09 PM MDT – 1.00-inch hail reported in an NWS warning area. NWS warning only.
• July 2 · 7:48 PM MDT – 1.50-inch hail detected by dual-polarization radar. Radar-detected hail track issued.
• July 2 · 8:39 PM MDT – 1.60-inch hail detected by dual-polarization radar.
• July 2 · 8:43 PM MDT – 1.00-inch hail reported in an NWS warning area. NWS warning only.
• July 2 · 9:11 PM MDT – 2.54-inch hail detected by dual-polarization radar.
• July 2 · 9:40 PM MDT – 2.04-inch hail detected by dual-polarization radar.

NWS warning areas were issued twice as the cell moved across the township. Several radar detections after 7:45 PM showed increasing hail sizes, with multiple radar-derived reports above 1.5 inches in diameter. The event concluded before 10:00 PM MDT.

Damage Assessment

Radar-detected hail measurements exceeded 2 inches on multiple returns during the late evening. Hail in the 1.0–1.6 inch range can crack vehicle windshields, dent sheet metal, and bruise siding and windows. Hail above 2.0 inches substantially increases the risk of broken glass, significant roof shingle damage, and severe body damage to exposed vehicles.

Field reports and the NWS warning areas indicate exposure across populated points in and near Mosby. Owners of vehicles parked outdoors, unprotected skylights, and low-slope roofing installed with three-tab shingles face the highest likelihood of repairable or replaceable damage. Photographs tied to time and location will be critical for claims and contractor scopes.

What Contractors Should Know

Begin field work with a documented safety plan and photographed pre-inspection. Record vehicle positions, roof access points, and any temporary water intrusion. Use date- and time-stamped photos with visible landmarks. Prioritize emergency tarping only where active leaks are present. Secure ladders and set fall protection for roof work.

Estimate roof damage in place before removing material. Look for bruised asphalt shingle granules, split fiberglass, and dent patterns on metal panels or HVAC units. For vehicles, document hail size with a scale reference and note the parking time if available. Prepare scope sheets that separate cosmetic panel dents from structural or glass failures. Coordinate with adjusters early and attach the radar-detected hail reports to inspection files.
