During the early morning hours of August 6, a high-end EF2 tornado touched down in the southeastern part of Tulsa, Oklahoma, forming along the leading edge of a bow echo within the eastern segment of a mesoscale convective complex that began sweeping through the state on the evening of August 5.
The tornado began at 1:19 a.m. CDT (06:19 UTC) in a residential neighborhood east of South Harvard Avenue and south of East 36th Street South.
Damage at the beginning of the path consisted of snapped trees and tree limbs and was rated EF1.
The tornado crossed South Yale Avenue, causing additional EF1 damage as wooden power poles were snapped.
A nearby 10-story mid-rise Charles Schwab Corporation office building had minor exterior damage and a few broken windows.
The tornado then reached high-end EF2 strength as it moved down East 41st Street, damaging or destroying numerous businesses in this area.
A T.G.I. Friday's location in the Highland Plaza shopping district sustained collapse of its roof and exterior walls, and at least 8 people had to be rescued from that location.
A dentist's office sustained major structural damage, while a Chipotle, a Whataburger, and an AT&T store had their roofs ripped off.
The tornado caused infrastructure damage to the BOK Financial Corporation's operations center, disabling its online, mobile and automated telephone systems.
Several other businesses and structures sustained major damage in this area, a large billboard was blown over, and vehicles were flipped.
Damage to ten of the affected businesses in the Highland Plaza district was so severe that city management designated them to be condemned.
Just past this area, the tornado struck the 18-story Remington Tower office building along Skelly Drive.
The tower sustained major damage to its facade and exterior, and had many windows blown out.
A nearby hotel was also damaged.
Continuing eastward, the tornado entered an industrial area of southeastern Tulsa.
An industrial building along East 42nd Street sustained EF2 damage, losing its roof and large portions of its masonry exterior walls.
Beyond this point, the tornado weakened to EF1 intensity as it moved along an east-southeasterly path through industrial areas, causing minor to moderate damage to warehouses and industrial buildings.
Structures in this area had roofing and paneling removed, and some had portions of exterior walls blown out.
Power poles were snapped as well.
Continuing at EF1 strength, the tornado crossed South Memorial Drive and impacted a residential neighborhood, where trees and tree limbs were downed and homes had windows blown out.
The EF1 tornado then crossed South Mingo Road into another industrial area, where several industrial buildings were damaged.
Crossing U.S. Route 64 and following East 51st Street South to the east, the tornado continued to produce EF1 damage as a motel and an industrial building sustained damage, and several trees and power poles were downed before the tornado dissipated near the intersection of East 51st Street South and South 145th East Avenue.
A total of 30 people were injured by the tornado.

The rare August tornado, the first to hit the Tulsa area since 1958 (and only the third to strike the area since official tornado records began being kept in 1950), injured 26 people – with two experiencing serious injuries – in the eastern part of the city.
Despite the presence of strong low-level rotation that was detected on radar, the Tulsa County Emergency Management Agency did not activate civil defense sirens in Tulsa proper as the local National Weather Service forecast office did not issue a tornado warning until 1:25 a.m. CDT (06:25 UTC), two minutes before it spawned an EF1 tornado that spanned a 2.9-mile-long (4.7 km) track across Broken Arrow, causing roof damage to numerous homes and bringing down several large tree limbs in the suburb.
A second EF1 touched down east of Oologah at 1:32 a.m. CDT (06:32 UTC), damaging several trees, barns and one home, and downed several electrical poles.
A fourth, weak tornado was later confirmed through damage
