Monetary damages were estimated. EPISODE NARRATIVE: Thunderstorms developed early in the afternoon, from near the Lawton area, northeast toward the Oklahoma metro area. Thunderstorms became severe relatively quickly as they moved through Caddo and Grady counties, and began to show signs of rotation as they moved toward western Oklahoma City. One supercell thunderstorm spawned several tornadoes as it moved through western and northern Oklahoma. Sporadic damage was reported along its path, some of it significant as it moved through northern Oklahoma county and southern Logan county. Other supercells developed near the same areas of Caddo and Grady counties and moved northeast. Some locations received several rounds of very large hail through the afternoon. Later in the afternoon, a second area of thunderstorms developed over northern Texas. Several supercell thunderstorms developed and moved northeast toward the Red River. One supercell thunderstorm moved northeast over Clay county and northwest Montague county. A tornado developed as it moved into Jefferson county near the Red River. It continued northeast through western Love county and into Carter County. Significant damage was reported in and around the Lone Grove area and over the far north sides of Ardmore. There were eight fatalities in and around Lone Grove. The tornado crossed Interstate 35 and eventually crossed into southern Murray county. Wind damage was reported in Coal and Atoka counties. Minor injuries were reported with the Atoka county thunderstorms. Monetary damages were estimated.

A brick home lost two of its walls and the roof was removed. Four other homes were also heavily damaged with roofs removed and walls damaged. Two barns were also damaged. The tornado crossed Interstate 35 near mile marker 21. A tractor trailer was blown off the interstate just south of this location. The state park sustained some tree damage on the southwest side of Lake Murray. This was the first of three tornadic events in two days for Oklahoma. The other two events occurred on the afternoon of May 8 and on May 9, 2003 (see appropriate storm data). The five tornadoes that occurred in south central Oklahoma all happened after midnight with the strongest tornadoes producing F2 damage. One large supercell produced the three strongest tornadoes of the night.
