Upton, WY Hail Storm – July 2025

Upton, WY saw two confirmed hail alerts on July 4, 2025, with peak hail at 1 inch. The storm has concluded.

What Happened

The first alert came at 4:18 PM MDT, with dual-polarization radar confidence for 1-inch hail. A second alert followed at 8:45 PM MDT, also carrying 1-inch hail confidence from dual-polarization radar.

Both alerts point to a hail-producing storm that held organized enough structure to produce repeat hail signals over the course of the day. The event was not a single isolated report. It was a multi-zone storm sequence across the Upton area.

The local timing places the first hail threat in the late afternoon and the second in the evening. That pattern matches a storm that remained capable of hail production after the first round had passed.

Damage Assessment

One-inch hail is a threshold size for roof, siding, vehicle, and exterior trim claims. The most common field impacts include bruised shingles, minor granule loss, cracked soft metals, and dents in gutters, vents, and roof accessories. Vehicles parked in the open can show roof and hood dimpling, with higher exposure on east- and west-facing sides depending on storm approach.

In a town like Upton, property damage often depends on the storm path through individual streets, not just the alert area. Houses on the fringe of the warning area may see little or no hail. Properties under the core hail path can show visible exterior marks even when the hail size stays near 1 inch.

Contractors should expect mixed loss patterns. A neighborhood can have roof claims without widespread siding damage. Another block can show vehicle impacts with little roof concern. Hail at this size does not usually produce the severe loss profile seen with larger stones, but it is large enough to trigger a detailed exterior inspection.

For adjusters and roof crews, the priority is separating superficial impact from functional damage. Check for soft metal deformation, collateral hits on gutters and flashing, and any slope-specific wear on shingles that may not be visible from the ground.

What Contractors Should Know

Field teams should treat this as a localized hail inspection job with two separate timing windows. Start with the first alert period around 4:18 PM MDT and then look again near 8:45 PM MDT for second-pass impacts. Properties with no obvious damage after the first round may still show signs from the later hail burst.

Focus on roofs, vehicle lots, and light-gauge exterior components. One-inch hail can leave limited but measurable impact on ridge caps, pipe boots, vents, condensers, window screens, and exposed trim. On steep roofs, test for bruising and mat fracture near ridge, eave, and slope transitions. On flatter surfaces, check for membrane hits and soft-metal dents that are easy to miss from street level.
