Jordan, MT Hail Storm – August 2025

Jordan, MT saw a concluded hailstorm on August 4, 2025, with confirmed hail up to 1.75 inches. Five NWS alerts tracked the storm from late afternoon into early evening.

What Happened

The first alert came at 4:41 PM MDT with dual-polarization radar confidence for 1.25-inch hail. A second alert at 5:40 PM MDT lowered the estimate to 1 inch, then the storm strengthened again with a 1.75-inch hail alert at 5:45 PM MDT.

Radar confidence held through the next cycle. Another 1.75-inch hail alert followed at 6:44 PM MDT, then a final 1-inch hail alert at 7:45 PM MDT as the storm moved through the Jordan area. The warning sequence covered a broad part of the local storm path and showed repeated large-hail signatures over a three-hour span.

The maximum confirmed hail size from this event was 1.75 inches.

Damage Assessment

Hail in the 1 to 1.75 inch range can produce visible roof, siding, window, and vehicle impacts, with the heaviest effects usually tied to the larger stones and the most concentrated part of the storm path. In Jordan, the repeated large-hail alerts point to a hail swath with more than one pulse of damaging hail.

Crews should expect asphalt shingle scarring, bruised soft metals, dented gutters, and fractured roof accessories in the hardest-hit sections. Metal surfaces can show clustered impact marks where the storm core held together longest. Exposed cars, farm equipment, and HVAC condensers are also likely inspection targets after a storm of this size.

For exterior loss work, document roof slopes, ridge caps, vents, soft metals, and downspouts separately. Hail at 1.75 inches can leave inconsistent damage across short distances, so one block or one side of a structure may show a different impact pattern than the next.

What Contractors Should Know

Use the alert sequence to narrow the canvass zone before field work begins. The storm produced multiple radar-derived hail estimates between 4:41 PM MDT and 7:45 PM MDT, which suggests a long-lived cell with shifting hail cores rather than a short pulse. Prioritize properties aligned with the repeated large-hail alerts first.

On-site inspections should start with roof planes that face the incoming storm path, then move to gutters, flashing, window screens, fence caps, and HVAC units. In mixed agricultural and residential areas around Jordan, also check barns, sheds, silos, and equipment yards. Large hail can leave a clear pattern on soft metals while leaving adjacent surfaces only lightly marked.

Record the size, type, and location of each impact point separately. Note any loss of protective granules, edge cracking, exposed mat, and fresh bruising on siding or trim. If two structures sit close together, inspect both. Hail fields of this size often vary sharply across a small radius.
