Winifred, MT Hail Storm – July 2026

Winifred, MT, late afternoon and early evening July 14, 2026, experienced large hail peaking at 3.78 inches as a multi-cell storm tracked through the area and is continuing to produce large hail.

What Happened

NWS alerts began at 5:15 PM MDT and continued through 10:26 PM MDT, generating 19 alerts covering Winifred and nearby notification zones. Thirteen alerts were detected by dual-polarization radar. Six were NWS warning only alerts. Radar detections included multiple reports above 1.5 inches. The largest radar-detected return in the alert stream measured 3.16 inches at 6:25 PM MDT. Other radar-derived peaks included 1.92 inches at 6:55 PM MDT, 1.76 inches at 8:37 PM MDT, and 1.68 inches at 10:26 PM MDT. A smaller NWS-only detection of 0.75 inch appeared at 9:56 PM MDT. The storm is active and tracking through the NWS warning area. Conditions may still be developing across the notification zones.

Damage Assessment

Radar and warning reports show hail ranging from roughly three-quarters of an inch up through the larger measured stones during the event. Repeated radar detections in the 1.0–2.0 inch band across the Winifred area indicate widespread potential for shingle bruising, denting to vehicle panels, and cracking of thin glazing and skylights on exposed structures. Radar detections above 2.0 inches raise the likelihood of broken windows, significant vehicle damage, and punctured or displaced roofing materials on affected parcels. The presence of very large measured stones increases the risk of structural damage to soft roofing materials and to unsecured outdoor equipment on properties inside the warning area. Inspectors and homeowners should expect variability along the storm path where radar returns were stronger and where multiple alerts overlapped.

What Contractors Should Know

Treat this as an active work safety environment. Hail remains possible while the storm is ongoing. Confirm that local NWS warning areas have lapsed for the specific property before mobilizing crews. Use aerial or remote inspection tools where safe and permitted. Prioritize documented photos and video with time and location stamps for every affected roof and vehicle. Temporary tarping should follow manufacturer and insurance protocols. Secure work zones against falling debris and unstable roof substrates.

Document visible damage by roof section and vehicle panel. Record the local alert timestamps and radar-detected hail sizes nearest each property. Coordinate with property owners and adjust scopes for localized heavy-impact areas where radar returns and multiple alerts overlapped. Expect follow-up inspections once the storm has fully passed and local spotter reports are available.
