Wyola, MT Hail Storm – July 2026

Wyola, Montana, experienced a multi-zone hail-producing storm on July 19, 2026, with peak radar-detected hail measuring 1.77 inches. The system produced multiple National Weather Service alerts across the late afternoon and early evening and has since concluded.

What Happened

The first NWS warning for the event issued in the late afternoon. At 4:42 PM MDT the NWS warned for hail up to 1 inch based on storm reports and warning criteria. At 5:28 PM MDT dual-polarization radar detected a larger hail core near Wyola; radar-derived hail estimates returned the 1.77-inch measurement. Three later NWS warnings issued between early evening and 8:14 PM MDT listed no additional hail reports and were issued as part of the ongoing watch and warning sequence as the system moved away.

The event combined NWS warning issuance and radar-detected hail. The storm affected multiple adjacent zones within the Wyola metro area before weakening. The storm is concluded and no active warnings remain for the area.

Damage Assessment

Radar-detected hail during the event reached sizes associated with localized vehicle denting and damage to roofing materials where exposure was prolonged. In Wyola, the pulse-like nature of the storm suggests concentrated impacts on exposed vehicles, outbuildings, and modern asphalt roofing installed without hail-rated underlayment.

Where hail fell in sustained bursts, expect shingle granule loss, bruising of composite and wood siding, and denting of metal surfaces. Wind-driven hail into glass presents a breakage risk for older single-pane windows. There are no verified spotter reports filed with the NWS for this event in public records; the primary evidence for the largest hail size is dual-polarization radar detection at 5:28 PM MDT.

What Contractors Should Know

Inspect roofs and vehicles in the Wyola area as soon as conditions allow. Start with a perimeter walk to identify concentrated granule loss, split or missing shingles, and indentations on metal panels. Photograph damage with time and location metadata. Prioritize repairs that prevent water intrusion; temporary covers should be secured within 48 hours where roof breaches are found.

Document the hail pattern and collect client statements about vehicle locations and exposure during the late afternoon into early evening. Measure and note dent size and typical impact density in affected areas. Work safely on wet and slick surfaces and coordinate with building owners on access and liability documentation before beginning repairs.
