Young, AZ Hail Storm – July 2026

Young, AZ experienced a hail-producing thunderstorm on July 20, 2026, with radar-detected hail up to 2.16 inches and multiple severe alerts across the metro.

What Happened

The storm developed in the early afternoon and produced a sequence of six severe hail alerts across the Young, AZ metro between 2:00 PM and 5:37 PM MST. The earliest strong radar detection occurred at 2:00 PM MST (21:00 UTC) and showed the largest radar-derived hail signature. Follow-up radar detections were issued around 2:35 PM (21:35 UTC), 3:19 PM (22:19 UTC), 3:42 PM (22:42 UTC), and 4:21 PM (23:21 UTC), with hail-sized signatures ranging from just over one inch up to roughly an inch-and-a-quarter in the mid- to late-afternoon returns. A final alert at 5:37 PM MST (00:37 UTC) was issued as an NWS severe thunderstorm warning without an accompanying dual-polarization radar hail signature.

Dual-polarization radar imagery provided the basis for the early and mid-afternoon detections. Those radar-derived alerts identified concentrated hail signatures moving through the metro and into outlying areas. The NWS warning late in the sequence covered the broader warning area for intense thunderstorms as the cells weakened and moved east. The event is concluded.

Damage Assessment

Large stones detected by radar during the event are capable of causing vehicle glass fracture and substantial denting to metal surfaces where exposure occurred. Mid-range hail signatures in the storm are consistent with common impacts to asphalt shingles, skylights, and unprotected siding. Smaller inch-class stones later in the sequence can bruise composite roofing and crack older single-pane glass.

Where hail fell over developed parts of Young, expect localized roof and vehicle impacts consistent with these size ranges. Inspectors should prioritize visible punctures, broken glass, and clustered dent patterns on sheet metal. Secondary damage such as water intrusion through compromised roof coverings is a principal follow-up risk in the 24–72 hours after the storm.

What Contractors Should Know

Immediate on-site priorities: document conditions with timestamped photos from multiple angles, measure representative hail stones where available, and note concentrated dent patterns on vehicles and metal roofing. Tarping and temporary waterproofing should target identified penetrations and open seams to limit secondary water damage. Use conservative staging—mobile crews should avoid wet, unstable slopes and take ladder and harness precautions on steep roofs.

Estimating and repairs: separate impact repairs from unrelated wear in estimates and record pre-existing conditions. For roofing, prioritize replacement of compromised shingles and flashings; for glazing, document cracked panes and track serial numbers for insulated units. Coordinate with insurers and property owners on scope, and schedule follow-up inspections within 72 hours to capture developing water issues.
