Happy Jack, AZ Hail Storm – August 2026

Happy Jack, AZ experienced a hail event on August 7, 2026, with a peak verified stone of 1.64 inches. The storm produced multiple radar-detected hail alerts and an NWS severe thunderstorm warning before concluding in the early evening.

What Happened

The storm began in the late afternoon and evolved through the evening hours. NEXRAD dual-polarization radar detected multiple hail cores that prompted four separate NWS alerts for the Happy Jack area.

• August 7 · 3:39 PM MST (22:39 UTC) – 1.00 inch hail detected by dual-polarization radar.
• August 7 · 4:56 PM MST (23:56 UTC) – 1.51 inch hail detected by dual-polarization radar.
• August 7 · 7:41 PM MST (02:41 UTC) – 1.00 inch hail detected by dual-polarization radar.
• August 7 · 8:53 PM MST (03:53 UTC) – 1.00 inch hail noted in an NWS severe thunderstorm warning.

Radar returns showed a compact hail-producing core that tracked broadly northeast through the Happy Jack metro footprint. Storm intensity peaked in the late afternoon to early evening window. The alert sequence combined multiple radar detections and a later NWS warning issued on observed storm behavior.

Damage Assessment

Radar-detected hail sizes in the alert sequence ranged from 1.00 to 1.51 inches across the affected cells. Hail at and above the 1.5-inch range is consistent with vehicle panel denting and the potential for asphalt shingle damage in exposed residential roofs in Happy Jack.

No spotter-verified structural collapse or widespread roof failure was reported in the available aggregated data for this event. Localized cosmetic and functional damage to vehicles, outdoor equipment, and roof coverings is the primary risk given the reported stone sizes and the storm timing through populated areas.

What Contractors Should Know

Schedule immediate exterior inspections for properties within the NWS warning area issued during the storm. Prioritize vehicle assessments, accessible roof inspections, and identification of compromised HVAC units and solar arrays. Use standardized roof inspection photos with scale references and multiple angles. Record observed hail sizes and note photoreference locations relative to property boundaries.

Secure tarping and temporary coverings only where water intrusion is present or imminent. Avoid rush repairs without proper documentation for insurance submissions. Provide clients with an itemized scope that separates cosmetic hail dents from functional roofing damage. Coordinate with insurers early and preserve photos, timestamps, and homeowner statements.
