Cheyenne, WY Hail Storm – June 2025

What Happened

A severe hail storm moved through the Cheyenne, WY metro on June 1, 2025, producing verified 1.25-inch hail late in the afternoon. Two NWS alerts carried radar and spotter verification, first at 4:20 PM MDT and again at 4:44 PM MDT.

Field reports lined up with that timing. At 4:30 PM MDT, the NWS Cheyenne office reported accumulating pea to dime sized hail with quarters and half dollars as the largest stones found during measurements. Two additional reports came in at 4:40 PM MDT through mPING, both listing quarter-size hail at 1.00 inch.

The storm remained focused on the Cheyenne metro during the late-afternoon period. Radar confidence stayed high enough for repeat warning coverage, and the field reports confirmed a hail core that was already putting down measurable stones before the second alert window closed.

Damage Assessment

The ground reports point to a short-duration but concentrated hail event with enough stone size to affect exposed roofs, soft metal trim, vehicles, and window screens in the hardest-hit parts of Cheyenne. The NWS office report is the strongest ground-truth point in this event. It documented accumulating hail with the largest stones reaching half-dollar size, which places the storm above routine nuisance hail and into the range where visible surface impact becomes more likely.

The 4:40 PM MDT mPING reports add a second data point from within the same storm window. Both reports listed quarter-size hail at 1.00 inch. That mix of 1.00-inch and 1.25-inch reports suggests a hail core with variation across a small area, which is common when a cell pulses over a metro zone rather than spreading uniform stone size across the full warning area.

For homeowners and adjusters, the most useful field cue is timing. The storm produced verified hail within a narrow afternoon window, and the reports indicate active stone accumulation rather than a brief hail burst that melted on contact. In practical terms, that calls for direct inspection of roofs, gutters, downspouts, siding, AC fins, skylights, and vehicle glass in the specific neighborhoods that sat under the hail core.

What Contractors Should Know

Cheyenne storms can shift across developed areas quickly, and this event did not linger long enough to leave a broad, even footprint. Crews should expect spotty impact patterns. One block may show light cosmetic marks while another, only a short distance away, shows heavier dings and bruising. The report from the NWS office makes that variability worth checking closely in and around the central metro.

Start with steep-slope roofs and metal surfaces. Look for granule loss, bruised shingles, bent vent caps, dented metal flashing, and impact marks on gutters and soft aluminum trim. Vehicles parked outside during the 4:20 PM to 4:44 PM MDT warning period should be reviewed for roof, hood, and mirror damage. Window screens and fence caps also deserve a close look where the hail core passed directly overhead.
