Parker, AZ Hail Storm – September 2026

A hail-producing thunderstorm passed through Parker, AZ, on September 16, 2026, producing 1.00-inch hail and prompting an NWS severe thunderstorm warning. The event was brief and concluded the same afternoon.

What Happened

A single NWS severe thunderstorm warning was issued at 3:56 PM MST on September 16 for 0.75-inch hail and covered the Parker warning area. Radar-derived hail detections were concentrated over the town during the late afternoon. The warning was designated as NWS warning only. The storm moved through on a compact track and weakened within an hour. Observations and radar returns indicate a limited hail core rather than an extensive swath. The event is recorded as concluded.

Damage Assessment

Hail of this magnitude most commonly causes cosmetic damage to vehicles and exterior building materials. Expect dents on aluminum and softer plastics. Composite and asphalt shingle roofs may show bruising or granular loss that can accelerate wear. Skylights and unprotected glazing are more vulnerable than standard tempered windows. Vegetation and exposed outdoor equipment can show shredding or surface scarring.

Field crews conducting inspections should document dent patterns and take near-field and context photos. Note location, orientation, and wind-exposed sides of structures. Collect repair estimates that separate cosmetic replacement from water-intrusion repairs. For roofing, flag spots with bruising or loose granules for prioritized monitoring; not all bruising requires immediate replacement, but it can reduce warranty life.

What Contractors Should Know

Start inspections with safety and evidence preservation. Photograph all hail impacts before lifting, cleaning, or making temporary repairs. Capture vehicle panels, roof areas, gutters, HVAC units, and skylights with a broad shot and a close-up. Use consistent reference scales in photos. Record the time and the property address as listed in the NWS warning area.

Prepare clear scopes of work that distinguish cosmetic repair from water-stopping measures. For roofs, document bruising, granular loss, and any compromised flashings. For glass and skylights, confirm whether impact produced cracks or only superficial marks. Secure temporary tarps or covers where water intrusion is possible. Coordinate with adjusters and provide dated photographic evidence to support recommended repairs and timelines.
