Cashion, OK Hail Storm – September 2026

A severe hail storm tracked through Cashion, Oklahoma on September 12, 2026, producing a peak hail size of 3.15 inches and moving northeast from late afternoon into early evening.

What Happened

The first National Weather Service warning for the system was issued around 3:24 PM CDT (20:24 UTC) for 1-inch hail in the broader warning area. NEXRAD dual-polarization radar began producing hail detections shortly afterward, with early radar echoes near 3:36 PM CDT (20:36 UTC) indicating stones around 1.35 inches. The storm maintained a northeastward track and produced multiple radar-detected hail cores through the evening.

Between mid- and late afternoon the radar-derived hail sizes increased. Notable radar detections included 1.98 inches at 5:06 PM CDT (22:06 UTC), 2.16 inches at 5:50 PM CDT (22:50 UTC), and sustained >2-inch returns from about 6:55 PM CDT (23:55 UTC) through 8:28 PM CDT (01:28 UTC). NWS warning-only messages continued to accompany the larger radar signatures at times, indicating the polygon-level alerts covered a wider corridor than the radar hail cores.

Field observers in the Cashion area recorded surface evidence late in the event. A social media post near 7:10 PM CDT (00:10 UTC) included photographs showing the largest stone as roughly twice the diameter of a U.S. quarter; an mPING entry around 7:15 PM CDT (00:15 UTC) reported an estimated 2-inch stone. Those spotter-verified observations occurred while radar still indicated strong hail cores moving through the region.

Damage Assessment

Surface observations within the Cashion vicinity consisted primarily of spotter-photographed stones and an mPING report estimating 2-inch hail collected on pavement. Local storm reports did not list a separate catalogue of structural failures tied to this event. Photographs submitted by observers show intact, hand-held specimens and pavement collections rather than photographs of large-scale structural collapse.

Radar detections above 2 inches were intermittent but recurrent between early evening and late evening. Those radar cores align with the timestamps of the spotter photos and the mPING entry in the Cashion area, suggesting a concentrated corridor of large hail passed through and adjacent to town. Vehicle panels and exposed outdoor equipment in photographed locations are the most-likely places to exhibit denting based on the size of stones captured in imagery. Claims investigators should correlate the 7:10 PM CDT and 7:15 PM CDT reports with local addresses inside the NWS warning area to establish timing and exposure.

What Contractors Should Know

Inspect roofs first at addresses inside the NWS warning area that were northeast of Cashion during the late-afternoon to early-evening passage. Prioritize asphalt shingle nails and granule loss, metal roof panel denting, and skylight glazing in areas where spotters photographed stones or where radar shows repeated >2-inch cores between 5:00 PM and 8:30 PM CDT. Document each observation with time-stamped, GPS-enabled photos and a scale object for comparison to the spotter photographs taken around 7:10 PM CDT and 7:15 PM CDT.
