Fort Supply, OK Hail Storm – June 2026

A strong hail-producing storm tracked through Fort Supply, Oklahoma late on June 21 into the early morning hours of June 22, 2026, producing up to 2.03-inch stones and multiple radar and spotter detections.

What Happened

The event began with an NWS warning issued at 6:48 PM CDT on June 21. Dual-polarization radar returned several hail cores during the late-evening period, including pronounced radar detections around 7:20 PM CDT and again near 8:16 PM CDT. The National Weather Service issued 56 separate alerts across the storm life cycle, alternating between radar-detected hail reports and warning-area updates.

Field observers played a key role in documenting surface impacts. Two mPING reports at 8:13 PM CDT described ping-pong-ball sized hail near Fort Supply. Overnight spotter logs recorded multiple quarter-size reports at 1:11 AM CDT and 2:12 AM CDT. Radar continued to flag smaller hail echoes through the pre-dawn hours, with NWS warning-only updates and spotter reports persisting into the 7:00 AM CDT hour on June 22.

The combined record shows an evening surge of stronger cores, a secondary pulse after midnight, and a string of lower-intensity detections in the morning. Spotter-verified observations are concentrated in and around the Fort Supply area at the times noted above.

Damage Assessment

Local spotter logs indicate surface impacts concentrated near the town of Fort Supply during the late-evening and early-morning pulses. The two mPING reports at 8:13 PM CDT identify a localized area that experienced larger-diameter stones during the primary convective pulse. The cluster of quarter-size reports documented at 1:11 AM CDT and 2:12 AM CDT shows renewed surface activity later along the same corridor.

Radar-detected hail cores passed directly over the Fort Supply vicinity during the stronger late-evening pulse and again in smaller cores after midnight. Those repeated passes over the same corridor increase the likelihood of cumulative surface effects in properties along the storm track identified by spotters. Observations do not include centralized damage assessments or quantified loss totals within the public field reports provided.

Contractors and adjusters should expect impact signatures focused where spotter reports and radar cores overlap geographically. Field logs show multiple discrete times of measurable hail at locations near town rather than a single extended swath of continuous ground impact.

What Contractors Should Know

Prioritize inspections for properties and vehicles in the immediate Fort Supply area where spotter reports occurred at 8:13 PM CDT, 1:11 AM CDT, and 2:12 AM CDT. Start with exposed metal surfaces, vehicle body panels, and ground-level equipment at sites closest to those reported times. Document each inspection with time-stamped photos and note proximity to the spotter coordinates when available.
