Cheyenne, WY Hail Storm – June 2025

What Happened

A severe hail storm moved through the Cheyenne, WY metro on June 2, 2025, with radar and spotter reports reaching 1.75-inch hail by late afternoon. The storm produced a series of eight NWS alerts from 3:47 PM MDT through 5:56 PM MDT.

The first alert at 3:47 PM MDT called for 1-inch hail, followed two minutes later by a 1.25-inch alert. By 4:38 PM MDT, radar and spotter confidence had increased to 1.75 inches. Additional alerts followed at 4:47 PM MDT, 4:50 PM MDT, 5:15 PM MDT, and 5:56 PM MDT, with hail sizes ranging from 1 inch to 1.75 inches.

Ground reports matched the rapid storm evolution. A trained spotter reported ping pong ball size hail at 5:39 PM MDT. Earlier, at 3:51 PM MDT, a report called in quarter size hail. Social media photos at 4:27 PM MDT also showed quarter size stones. The sequence points to a storm that kept producing hail across the metro into the evening.

Damage Assessment

The field reports show a storm that reached beyond isolated hailstones. Emergency managers reported down trees and power outages around Torrington at 5:27 PM MDT. Reports near Lingle at 5:51 PM MDT described creeks overflowing their banks. Those locations are outside the Cheyenne metro, but they place the broader storm complex in a zone of repeated severe impacts through eastern Wyoming.

In Cheyenne itself, the early reports centered on quarter size hail before larger stones were confirmed later in the afternoon. That progression suggests multiple pulses within the same storm line rather than a single short burst. The 5:39 PM MDT trained spotter report of ping pong ball size hail fits that later intensification.

The radar-derived alerts also showed a persistent hail threat. The sequence moved from 1 inch to 1.25 inches, then to 1.75 inches, then back through 1 inch, 1.25 inches, and 1.5 inches as the storm evolved. For property owners, that pattern points to repeated exposure across the warning area rather than a one-time pass.

No single report in this set describes structural loss in Cheyenne. The available evidence does show hail large enough to break soft roofing materials, dent exposed vehicles, and leave visible impact on siding, screens, and landscaping where the stones fell directly.

What Contractors Should Know

This event favors a targeted roof and exterior sweep across the Cheyenne metro, with the earliest attention on properties hit during the 3:47 PM to 4:50 PM MDT window. The quarter size hail reports came first. The larger radar-confirmed alerts followed later in the afternoon. Roofs with prior wear, ridge exposure, or marginal shingle adhesion should get priority.

Crew staging should account for a long-lived storm sequence, not a single impact point. When hail escalates from 1 inch to 1.75 inches across the same afternoon, claim volume often comes in waves. Properties with vehicle damage, screen damage, and minor siding impacts may surface before roof leaks are obvious. Document exterior impact early.
