Valliant, OK Hail Storm – March 2026

What Happened

A severe hail storm moved through the Valliant, OK area on March 11, 2026, with verified 1-inch hail and a mix of radar-derived and warning-based alerts through the day. The event started before midnight and continued into the afternoon, with nine NWS alerts issued between 11:52 PM CDT and 3:19 PM CDT.

Dual-polarization radar supported the first alert at 11:52 PM CDT, then again at 6:34 AM CDT and 7:16 AM CDT. Other alerts at 5:10 AM CDT, 8:16 AM CDT, 9:32 AM CDT, 12:11 PM CDT, 12:44 PM CDT, and 3:19 PM CDT were issued on warning-area confidence alone. The pattern points to repeated hail potential across the warning area rather than a single short-lived burst.

Ground reports during the same period showed damaging wind and tornado impacts in nearby areas, including a 12:25 AM CDT report of a roof partially peeled back near Garvin and a 12:30 AM CDT tornado report with snapped trees, roof loss, and a residence that sustained heavy structural damage near Rhoden Road. A 12:32 AM CDT spotter report also noted trees and powerlines downed on Rhoden Road west of Broken Bow.

Later morning reports continued to show tree damage in the broader region. At 6:50 AM CDT, a small softwood tree trunk was snapped and downed across FM 1818 south of US 69 and west of Zavalla. Additional spotter reports at 7:06 AM CDT and 7:15 AM CDT described snapped trunks north of Zavalla, and a 7:42 AM CDT report noted one uprooted tree and another snapped along FM 1992 north of TX Hwy 103.

Damage Assessment

The field reports show a storm complex with more than hail in the mix. Near Garvin and Broken Bow, reports point to roof damage, snapped trees, downed lines, and a tornado path that damaged homes, outbuildings, and heavy tree cover before lifting near Highway 3.

For Valliant and the surrounding warning area, the hail alerts sit inside a broader severe-weather episode that produced verified surface damage across multiple counties and communities. The hail itself reached 1 inch in the mapped alerts, but the on-the-ground reports indicate the system also brought enough wind and rotation to produce structural losses, especially in exposed rural spots and along tree-lined road corridors.

The damage pattern is uneven. Some reports show isolated tree loss. Others describe more concentrated impact near residences and farm structures. The 12:30 AM CDT tornado narrative near Rhoden Road included snapped and uprooted trees, roof damage on multiple homes, and a barn or shed with roof damage. That kind of clustered loss is consistent with a fast-moving severe line that can shift from hail to wind and tornadic damage over a short distance.

No hail-specific hail pad or roof survey is listed in the field reports provided for Valliant, so the public record for this event is stronger on storm intensity and regional damage than on building-level hail observations. The confirmed hail size remains 1 inch, with repeated NWS hail alerts supporting the storm profile across the day.
