What happened

The episode as NWS TSA wrote it up.

Summary of events for June 24 1999:A line of thunderstorms formed along a southeastward-moving outflow boundary on the morning of June 24. These thunderstorms eventually moved across all of eastern Oklahoma. Many locations across eastern Oklahoma experienced wind gusts of 40 to 50 miles an hour, though a few storms along in the line pulsed up enough to briefly produce marginally severe wind and hail. This line of storms also produced locally heavy rainfall amounts with most locations receiving from 3/4" to 1 1/2" of rain.
