What happened

The episode as NWS TSA wrote it up.

Summary of events for February 6 1999:Thunderstorms first fired up on the afternoon of February 6 along a stationary boundary stretching roughly from Okemah to West Siloam Springs. By late afternoon, one thunderstorm traveled northeast along this boundary, producing torrential rains causing rainfall totals to exceed two inches and causing sporadic flooding along the way. By the time this storm reached Adair County, it produced some marginally severe wind gusts. Further south, a line of thunderstorms moved across southeast Oklahoma during the late afternoon and early evening. Increasing upper level winds associated with an approaching upper level low caused this line of storms to produce locally damaging winds on its track across southeast Oklahoma. By late evening, the center of the upper level low, which was located northwest of Tulsa, caused isolated thunderstorms to form over Pawnee and Osage Counties. One of these storms produced a report of marginally severe hail.
