Grouse Creek, UT Hail Storm – July 2025

What Happened

A severe hail storm moved through Grouse Creek, UT, on July 4, 2025, with 1-inch hail verified in the warning area and field reports tied to late-afternoon storm activity. The event concluded after three NWS alerts, with the strongest hail signal first detected at 3:38 PM MDT and additional verified alerts later in the evening.

The first alert at 3:38 PM MDT carried a 1-inch hail signal from dual-polarization radar. Two later alerts, at 5:21 PM MDT and 5:55 PM MDT, both carried 1-inch hail confidence backed by radar and spotter verification. The sequence points to repeated hail production through the afternoon and into early evening across the broader storm path.

Field reports added ground truth to the radar picture. A report at 5:40 PM MDT described a downed tree in Kaysville from thunderstorm winds, with nearby mesonet stations recording gusts of 48 and 54 mph. A separate report at 6:00 PM MDT noted a photo received via social media, with the time estimated by radar, and confirmed 1-inch hail. Those reports align with a storm that produced both hail and wind across the wider metro corridor.

The timing places the most active period in the late afternoon and early evening. The storm did not pass as a single pulse. It produced a series of verified hail signatures, then left behind spotter-confirmed evidence of surface impact in the report stream.

Damage Assessment

The field reports show a storm with enough hail and wind to reach the ground in more than one place. The 6:00 PM MDT photo-based report confirmed 1-inch hail. The 5:40 PM MDT wind report in Kaysville documented a downed tree and 48 to 54 mph gusts from nearby mesonet stations.

That combination points to a mixed impact pattern. Hail fell at verified 1-inch size, and thunderstorm winds were strong enough to topple a tree in a nearby report location. The report set does not show a wide, catastrophic damage field. It does show a storm capable of producing localized impacts beyond hailstones alone.

For contractors, the first check is exposed property in the storm path. Look at roof slopes, soft metal, vents, and screens where 1-inch hail can leave visible bruising or punctures without widespread failure. Check for shingle loss near ridgelines and edges where wind can compound impact.

The wind report matters for inspection routes as well. A downed tree in Kaysville with gusts in the 48 to 54 mph range suggests the storm carried damaging wind on the same afternoon as the hail reports. That calls for a wider exterior walkaround than a hail-only visit. Look for fence movement, fascia hits, loose trim, and branch impact on vehicles or siding.

In rural and edge-of-town settings around Grouse Creek, access can also slow documentation. Photograph roof planes, soft metals, and collateral tree contact before repairs start. Separate hail marks from wind-driven debris strikes. On multi-zone storms like this one, the damage pattern can vary block by block.
