Casper, WY Hail Storm – June 2025

Casper, WY saw a concluded hail event on June 24, 2025, with verified hail reaching 1.75 inches across the metro area. The storm produced multiple hail alerts from late afternoon into the early morning hours.

What Happened

The first hail alert came at 4:56 PM MDT, with dual-polarization radar indicating 1-inch hail. A second 1-inch alert followed at 5:23 PM MDT. Hail signals returned later in the evening, with 1.25-inch hail indicated at 9:39 PM MDT.

Radar confidence increased again at 10:10 PM MDT and 10:48 PM MDT, both with 1.5-inch hail. The peak came at 11:13 PM MDT, when dual-polarization radar supported a 1.75-inch hail estimate. Two later alerts followed overnight, with 1.25-inch hail at 12:09 AM MDT and 1-inch hail at 1:14 AM MDT.

The alert sequence shows a storm that persisted through multiple rounds of hail-producing activity. The highest verified size of 1.75 inches placed the event in the larger hail range for the Casper area on this date.

Damage Assessment

Hail in the 1-inch to 1.75-inch range can produce mixed roof, siding, window, and vehicle impacts across a metro area. In Casper, the repeated hail alerts suggest more than one pass through the warning area, which can leave uneven damage from one neighborhood to the next.

At 1 inch, contractors should expect shingle bruising, soft metal dents, and damage to outdoor equipment. At 1.25 inches and 1.5 inches, asphalt shingles, roof vents, gutters, and vehicle panels often show more visible impact. At 1.75 inches, the field should include a closer look at roof slopes with aging shingles, exposed trim, skylights, and properties with prior wear.

Inspection priority should remain on roofs, then gutters, downspouts, window screens, AC fins, and vehicle fleets. Interior water intrusion can follow if impact marks coincide with lifted tabs, cracked flashing, or damaged sealant around penetrations.

What Contractors Should Know

This event covered a broad metro-scale area with several hail cycles through the evening and overnight period. Crews should sort claims by time window, location, and roof age before field work begins. Properties closer to the later 1.5-inch and 1.75-inch alerts deserve faster review, especially where reports include brittle shingles, granule loss, or dented soft metals.

Lead intake should stay specific. Separate early 1-inch reports from the later peak hail size. Document the exact address, visible impact points, roof slope, and any related exterior damage at the same visit. If the home or commercial roof has multiple additions, compare each plane rather than treating the structure as a single loss.

Vehicle inspections and exterior asset checks should follow the same pattern. Fleets, HVAC units, skylights, patio covers, and gutters can show hail impacts even when roof damage is limited. In a storm sequence like this one, the strongest claims often come from sites near the later evening peak, not the first alert.
