What happened
The episode as NWS TSA wrote it up.
Summary of events for April 4-5 1999:After a day of dry weather, high humidity air invaded southeast Oklahoma on Easter afternoon, April 4. The increase in instability allowed widely scattered severe thunderstorms to form. These storms produced hail as large as quarters.As a dryline approached from the west on the morning of April 5, a line of thunderstorms moved across the area. One thunderstorm in this line moved east along the I-40 corridor, producing marginally severe hail and winds. The big story of the morning, however, was a brief tornado touchdown along the line in Wagoner County.
The radar
The Western Arkansas radar (KSRX), 180 km away, was scanning. The volume nearest the first event began at 21:41 UTC.

The tornado moved north-northeast through the park, downing several trees and causing minor damage to two vehicles and two campers. One of the campers set down on one end of a pickup truck. The gate attendants' trailer was moved six feet. The tornado destroyed an empty boat dock before eyewitnesses reported it moving into Fort Gibson Lake as a waterspout.
