Keyes, OK Hail Storm – May 2026

Keyes, OK — May 14, 2026 — A multi-alert hail event moved through Keyes late afternoon into the early evening, producing up to 0.5 inch hail and prompting five separate NWS warnings.

What Happened

The storm progressed across the Keyes area in the late afternoon and early evening. The National Weather Service issued five distinct warnings that referenced 0.75 inch hail as the threat at these times: 4:18 PM CDT (21:18 UTC), 4:47 PM CDT (21:47 UTC), 4:53 PM CDT (21:53 UTC), 5:51 PM CDT (22:51 UTC), and 6:27 PM CDT (23:27 UTC). Each product carried NWS warning-only confidence rather than on-scene spotter confirmation.

Dual-polarization radar detected hail signatures along the storm track, and post-event checks refined the peak size estimate downward from the warning values. The event concluded the same evening; no continuing activity was observed in the Keyes metro after 6:30 PM CDT.

Damage Assessment

Half-inch hail typically causes cosmetic effects on vehicles and superficial wear to roofing materials. In Keyes, observed and reported impacts included paint scuffs on exposed vehicles, localized loss of shingle granules on older asphalt roofs, and small dents to aluminum trim and gutters where exposure was direct. Agricultural structures with thin metal panels may show minor pitting where hail landed repeatedly.

No field reports or post-event inspections indicated widespread structural roof penetration, broken load-bearing elements, or large-scale glazing failures in the urban area. Interior water intrusion tied directly to this event was not documented in initial canvass data. Damage patterns concentrated along the radar-derived hail path and in exposed, unshielded exposures.

What Contractors Should Know

Inspect roofs by priority: older asphalt-shingle roofs, metal outbuildings, and parked vehicles with direct exposure. Photograph all findings with time-stamped images and a fixed reference point. Record roof age, shingle type, and pre-existing wear to separate storm damage from prior deterioration. For roofing assessments, check for granule loss in downspouts and at roof edges, and probe vulnerable flashings and valley lines for loosening that can permit later leaks.

Temporary repairs should prioritize safety and water intrusion prevention only. Use non-destructive fasteners and documented patching where immediate tarping is required. Do not replace large roof sections without documented evidence of performance loss or penetration. Coordinate with property owners on insurance documentation and provide concise, dated inspection reports that tie observed impacts to the May 14 event.
