Stanford, MT Hail Storm – August 2025

What Happened

A severe hail storm crossed the Stanford, MT area on August 1, 2025, with a peak verified hail size of 2 inches and multiple warning-area alerts through the afternoon and evening. The strongest ground report came from Buffalo at 5:05 PM MDT, where spotters reported two separate instances of golf ball to 2-inch hail.

The first alert came at 2:31 PM MDT with 1-inch hail and radar plus spotter verification. A second 1-inch hail alert followed at 3:42 PM MDT on dual-polarization radar. By 5:10 PM MDT, the storm had intensified enough to support a 1.75-inch hail alert with radar and spotter verification. Two later alerts at 9:34 PM MDT and 9:56 PM MDT carried 1.25-inch hail estimates from dual-polarization radar.

The timing shows a long-lived storm cluster, not a brief pulse. The Buffalo report arrived during the late-afternoon peak, between the earlier 1-inch alerts and the evening 1.25-inch detections. That sequence places the strongest hail core in the middle of the event window.

Damage Assessment

Field reports point to a sharp hail swath rather than scattered nuisance stones. The Buffalo spotter report of golf ball to 2-inch hail indicates large stones at the surface, not just radar-supported hail aloft. That report came from a populated point in the storm path and gives the event its clearest ground-truth signal.

The warning-area alerts were consistent with a storm that maintained hail production for several hours. The 1-inch reports in mid-afternoon, the 1.75-inch alert near 5 PM MDT, and the later 1.25-inch detections all point to repeated hail growth within the same system. For roofs, siding, vehicles, and exposed crops in and near the Buffalo area, the most important field note is the size and timing of the stronger hail core during the late-afternoon pass.

No separate damage survey was provided in the source material. The verified report remains the key public record for this event. It confirms that the storm produced larger hail at the surface than the earliest warning-area estimates suggested.

What Contractors Should Know

Contractors working Stanford and the surrounding Buffalo corridor should focus on late-afternoon impact points first. The strongest verified hail fell at 5:05 PM MDT, after two earlier 1-inch alerts and before the evening radar detections. That sequence suggests layered impact, with the most severe roof, screen, and exterior damage more likely along the middle portion of the storm path.

Start canvass work with homes, shops, and farm structures near Buffalo and then expand outward along the broader warning area. Check soft metal, ridge caps, vents, north-facing roof slopes, and vehicle surfaces. The report of golf ball to 2-inch hail supports a review for bruised shingles, cracked skylights, dented trim, and torn screens. Agricultural property near the path deserves the same attention, especially where fields and equipment sat exposed during the late-afternoon core.
