Bartlesville, OK Hail Storm – April 2026

What Happened

Bartlesville, OK was hit by a long-lived hail storm on April 15, 2026, with spotter-verified reports reaching 4 inches and multiple radar-derived hail detections across the afternoon and evening. The first NWS alerts called for 1-inch hail around 1:59 PM CDT, and the storm kept producing hail into late evening, with another NWS alert at 11:29 PM CDT still showing 0.75-inch hail.

By midafternoon, the storm had become more intense. NWS alert sizes climbed from 1 inch to 1.25 inches, then 1.75 inches, before dual-polarization radar indicated 2-inch hail at 4:47 PM CDT. Spotter reports filled in the same window. At 4:37 PM CDT, a report tied to radar timing described hail around baseball size, and at 4:40 PM CDT two separate spotter-verified reports placed hail at 4 inches. Additional reports at 4:41 PM CDT and 4:50 PM CDT backed up 2-inch to 2.5-inch hail in the same general storm period.

The hail continued in waves after that peak. Alerts at 5:23 PM CDT, 6:28 PM CDT, and 7:00 PM CDT showed repeated 1.25-inch to 1.5-inch hail. A dual-polarization radar detection at 8:31 PM CDT again showed 1-inch hail, and a spotter report at 9:00 PM CDT placed another hail burst in the evening. The storm did not move through as a single short pulse. It produced repeated hail cores across the warning area for most of the day.

Damage Assessment

The field reports show a surface impact centered on large hail, with the most serious damage tied to the late-afternoon peak when 2.5-inch to 4-inch stones were reported. One report from 4:32 PM CDT described tennis ball-size hail in Osawatomie with multiple homes and vehicles damaged, plus cracked and broken windows and windshields. Around the same time, downtown Paola saw a measured 2.5-inch report, and another report at 4:34 PM CDT described sporadic 2-inch stones.

For Bartlesville and the surrounding metro, the damage picture is dominated by repeated impacts rather than one brief core. Radar showed multiple hail-size increases through the afternoon, and spotter reports confirmed larger stones during the same period. That pattern supports roof, siding, gutter, vehicle, and skylight checks in the affected corridor, especially where hailstones reached 2 inches or larger.

The report record also includes two 2-inch hail observations relayed through social media at 4:50 PM CDT and another 2-inch image shared by broadcast media at 5:45 PM CDT. Those details sit between the larger 4-inch spotter-verified reports and the later 1-inch radar detections, which points to a storm with several embedded hail bursts rather than one clean peak.

No single damage type appears across the entire path. The reports are clustered around broken vehicle glass, roof strikes, and visible hail accumulation in the hardest-hit spots. Areas that saw only 1-inch to 1.25-inch alerts likely had lighter impact, while the larger spotter-verified stones line up with the sections of the storm most likely to produce insured losses.
