Surveys conducted by teams in the NWS Norman and NWS Tulsa forecast areas in early to mid May 1999 revealed that 63 tornadoes occurred during the afternoon and evening of May 3, 1999, and the early morning hours of May 4, 1999 in the state of Oklahoma. A total of 58* tornadoes occurred in the NWS Norman forecast area in Oklahoma, Logan, Cleveland, Pottawatomie, and Lincoln Counties in central Oklahoma. A total of 6* tornadoes occurred in the NWS Tulsa forecast area in Okfuskee and Creek Counties in central Oklahoma. *The 52nd tornado of this large tornado outbreak began in the NWS Norman forecast area in Lincoln County, and then crossed over into NWS Tulsa forecast area and traveled through Creek County.

As the weather system that spawned the earlier tornadoes progressed through the region, additional thunderstorms developed during the mid to late morning hours of May 4, 1999 and produced an additional 9 tornadoes mainly in eastern Oklahoma. Since less than 6 hours occurred between the end of the original 63 tornadoes and start of the additional 9 tornadoes, the latter tornadoes have been included in the list as part of this severe weather/tornado outbreak. Note: The first 63 tornadoes in the event include a color-coded tornado ID based on the parent supercell that spawned the particular tornado in Oklahoma on May 3 and the early morning hours of May 4, 1999. These IDs match those on the expanded outbreak map for the May 3-4, 1999 event.
