Jordan, MT Hail Storm – August 2025

What Happened

A severe hail storm moved through Jordan, Montana, on Aug. 1, 2025, producing 1.75-inch hail during the early evening. The storm was concluded, with one NWS alert area tied to the event and radar plus spotter verification on the peak hail report.

The first alert came at 8:10 PM MDT, when dual-polarization radar indicated hail near 1.75 inches as the storm crossed the Jordan area. A spotter later reported golf ball sized hail at 8:30 PM MDT, matching the radar-derived size estimate and confirming the storm’s hail core at the surface.

The report timing places the main hail period in the early evening, after daylight heating had started to ease but while storms were still organized enough to produce a concentrated hail core. The local report and the radar signal aligned within 20 minutes. The confidence level on the alert reflects that match between radar and ground truth.

Jordan sits in an open part of eastern Montana, where storms can track for long distances with limited obstruction. In this case, the hail report was not isolated in the data. It came from a verified storm path with a single alert area and a matching field observation from the same event window.

Damage Assessment

The ground reports point to a brief but serious hail core over the Jordan area. Golf ball sized hail is large enough to leave visible impact on exposed vehicles, siding, windows, and soft roof coverings. The report was spotter-verified, which places it in direct alignment with the radar estimate rather than in a broad warning footprint alone.

Because this was a single-zone event, the impact picture is straightforward. The hail did not spread across a wide cluster of alerts. It was concentrated in one concluded storm track, with the strongest report centered on the 8:10 PM MDT to 8:30 PM MDT window. That timing suggests the heaviest surface hail fell quickly rather than over an extended period.

Field crews reviewing this event should expect isolated but clear signs of hail impact in the most exposed parts of town and along the storm path. On roofs, that usually means fresh bruising to asphalt shingles and scattered impact points on vents, skylights, and ridge accessories. On vehicles, the first check should be hoods, roof panels, mirrors, and rear glass. On metal siding and outbuildings, look for impact marks that line up with the main hail window rather than older weathering.

The report data does not show a broad wind-driven damage pattern. The emphasis stays on hail. That keeps the assessment centered on the verified surface report and the radar-confirmed hail size.

What Contractors Should Know

Jordan is a small market, but the storm path matters more than the town size. The verified report came from the early evening window, so contractors should prioritize properties aligned with the storm path rather than the entire metro label. The best inspection leads will be the addresses closest to the verified hail report and the storm’s downstream track.
