WSR-88D Twin Lakes, OK (KTLX) Radar Reflectivity Image at 9:05 PM CDT on May 29, 2004During the afternoon and evening of May 29, 2004, a cyclic supercell thunderstorm moved through west-central and central Oklahoma producing tornadoes, large hail, and high winds. The supercell formed in western Oklahoma within a line of thunderstorms that initiated near the dry line. Most of the other storms either dissipated or moved northward into Kansas, leaving this particular supercell as the dominant storm in Oklahoma during the late afternoon and evening hours.

The supercell tracked through Custer, southern Blaine, northern Canadian, southern Kingfisher, northern Oklahoma, and southern Logan counties, just skirting the northern Oklahoma City metro area. The storm continued to produce large hail, high winds, and/or tornadoes through northern Lincoln and southern Payne counties before moving into Creek County and leaving the NWS Norman area of responsibility by 11:30 PM CDT (10:30 PM CST). The supercell would move through northeastern Oklahoma, including the Tulsa metropolitan area, before dissipating just east of the Arkansas state line in Delaware County during the early morning hours of May 30, 2004.

The supercell produced 10 tornadoes in NWS Norman area and another 6 tornadoes in the NWS Tulsa area in northeastern Oklahoma. It took a track similar to, and just north of the track taken by another cyclic supercell that had occurred slightly more than a year earlier on May 9, 2003.

The supercell that traversed Oklahoma was part of a larger outbreak of severe weather that occurred On May 29-30, 2004, in the central Great Plains. Numerous reports of tornadoes were received from the region, including the states of Kansas, Missouri, Nebraska, and South Dakota as depicted in the Storm Prediction Center's preliminary storm reports map for May 29-30, 2004.
