19:56Z EF4 KTLX OK Mcclain Newcastle The violent Newcastle-Moore tornado was first observed developing about one-half mile south of State Highway 37 in northwest Newcastle to the east of Rockwell Avenue.

19:58Z EF0 KTLX OK Stephens Marlow A brief tornado was reported via Spotter Network near Marlow. No damage was reported and the tornado lasted a very short time.
20:04Z EF5 KTLX OK Cleveland Moore The violent Newcastle-Moore tornado moved into Cleveland County from McClain County as it moved northeast across the Canadian River near Interstate 44. The tornado then turned more east and then east-northeast after crossing Interstate 44. Violent EF4 damage was again observed as it began to move into progressively higher density residential areas approaching May Avenue.||The center of the large tornado path passed near SW 149th Street and Western Avenue. After crossing Western Avenue, numerous buildings were destroyed and horses killed at Orr Family Farm. Two storage tanks estimated to weigh approximately 10 tons were lifted from Orr Family Farm and landed about one-half mile east. Moving east, the tornado destroyed much of Briarwood Elementary School, where the NWS storm survey team initially rated the damage as EF5. However, further evaluation indicated that an EF4 rating was more appropriate at the school. Despite the destruction of this elementary school during school hours, no fatalities occurred at the school. As the tornado continued to move east and east-northeast, it moved through much more densely populated suburban neighborhoods of southwest Oklahoma City and Moore where violent destruction was widespread and a few houses were rated EF5. The width of EF4 and greater damage was up to 250 yards wide as the tornado moved through neighborhoods east of Western Avenue. The first two fatalities occurred in a house in the neighborhood just east of Briarwood Elementary, with another fatality in a house as the tornado approached Santa Fe Avenue. ||After crossing Santa Fe Avenue, the tornado moved through more suburban neighborhoods and toward Plaza Towers Elementary School. Damage to the school was extensive and seven children were killed when a wall collapsed at the school. Nine other people were killed in eight different neighborhood homes within one-quarter mile of Plaza Towers Elementary, most occurring just south of the school.||The tornado turned northeast as it approached Telephone Road, made a loop near the intersection of Telephone Road and 4th Street, then moved southeast crossing the interstate. Three people were killed when a convenience store along Telephone Road was destroyed. Crossing Telephone Road, the tornado inflicted significant damage to the Moore Medical Center, a post office and numerous businesses along Telephone Road and Interstate 35. Although the tornado was more narrow after crossing Interstate 35, it continued to produce EF4 damage in neighborhoods east of the interstate as it curved east and then again east-northeast. One fatality occurred at a business just east of the interstate, and one final fatality occurred in a home between Eastern Avenue and Bryant Avenue. Consistent EF4 damage continued until the tornado passed SE 4th Street just east of Bryant Avenue. Moving east from Bryant, the tornado continued to produce EF2 damage with isolated EF4 damage noted. The density of housing also decreased east of Bryant as the tornado moved east and east-northeast before dissipating east of Air Depot Blvd. between SE 119th Street and SE 134th Street in southeast Oklahoma City.||Overall, over 300 homes experienced EF4/EF5 damage along the tornado path. Of the 212 direct injuries documented from this tornado, 207 are estimated to have occurred in Cleveland County.
