Madill, OK Hail Storm – May 2026

Madill, Oklahoma experienced a short-lived severe thunderstorm on May 28, 2026 with hail up to 1 inch. The event produced a single NWS severe thunderstorm warning and concluded in the late afternoon.

What Happened

The storm moved through Madill during the late afternoon on May 28, producing hail and brief heavy rain. At 3:53 PM CDT the National Weather Service issued one severe thunderstorm warning noting 0.75 inch hail in the warning area; the warning is recorded as NWS warning only. Radar-detected hail echoes persisted for a few minutes as the cell tracked eastward across the city limits before weakening.

Storm status is concluded. No additional NWS alerts were issued for this cell after the 3:53 PM CDT warning. Available observations indicate a compact hail core with maximum stones reaching 1 inch in diameter and a dominant size near three-quarters of an inch through most of the affected area.

Damage Assessment

Hail up to 1 inch in diameter typically causes cosmetic damage rather than structural failure. Expect surface impacts such as chipped vehicle paint, dents to soft metal panels on cars and light trucks, and scuffing or pitting on vinyl siding. Asphalt shingles may show granular loss and bruising where hail struck at higher angles.

Landscaping damage is likely where plants and garden vegetation were exposed. Small, non-structural items left outdoors can incur breakage. Roof membranes and exposed HVAC condensers can show denting and abrasions that accelerate wear if not addressed. No reports of large-scale structural collapse or life-threatening damage are associated with this event in Madill at the time of this report.

What Contractors Should Know

Perform a targeted inspection of roofing surfaces for granular loss, split or bruised shingles, and displaced flashings. Photograph damage with scale references and record compass-facing roof aspects. Check gutters and downspouts for accumulated shingle granules. Inspect metal components including HVAC housings, soffit vents, and siding panels for dents and penetration. Prioritize properties with south- and west-facing exposures, where hail impact angles tend to be most damaging in late-afternoon storms.

Document vehicle and equipment damage on site and advise owners to retain debris and damaged materials for claims. Where roofing damage is marginal, use adhesive lifts or magnet tests to quantify denting on metal panels. Schedule follow-up inspections after wind or rain events that could reveal secondary leaks. For any repair scope, provide measured estimates for shingle replacement, localized flashing repairs, and condenser housing repair or replacement.
