Extensive straight-line wind damage occurred with a tornadic thunderstorm as it tracked across Oklahoma County. The damage occurred from Lake Hefner east across southern sections of The Village and northern sections of Nichols Hills, then northeast across northern Oklahoma City, crossing Interstate 35 in the vicinity of Hefner Rd and 122nd Street. The damage path then narrowed about 1 mile southwest of I35, from approximately 1-2 miles wide to near 3/4 mile wide. The damage path dissipated over extreme southeast Edmond. Estimated path length was 16 miles. Maximum width was 2 miles at points between Lake Hefner and the Broadway Extension. 105 MPH winds were measured at Lake Hefner by a media Chaser. Widespread damage to power lines (40,000 customers of OG&E), trees, roofs, antennas, signs, and windows occurred. The WKY broadcast tower, designed to withstand 125 mph winds, was toppled in the area between Kelly and Broadway Ext., and just south of Britton Rd.

This tornado touched down as a waterspout over Lake Hefner and moved east to dissipate between May Avenue and Lake Hefner Parkway. Total path length was approximately 3/4 mile and its width was approximately 50 yards. Numerous boats in dry dock suffered damage at the Oklahoma City Boat Club as the tornado passed slightly south of the marina. Boats that were in the water suffered little, if any, damage. Damage to the OKC Boat Club facilities and nearby boats was estimated at $250 K. Traffic signs along the east shore of the lake were bent and a small storage shed was destroyed approximately 1/8 mile south of the OKC Boat Club. Minor roof damage occurred to homes immediately east of Lake Hefner Parkway.

Reported near Hefner Parkway and Britton Road.

This tornado formed near NW 84th Street and Walker and traveled northeast until dissipating immediately east of the Broadway Extension 1/4 mile south of Britton Road. Total path length was 3/4 mile. Path width approximately 50 yards. This tornado was rated F1(73-112 mph). Along the damage path, a large portion of the roof decking was removed from a home on the southeast corner of 84th and Walker. Street signs also were torn from the ground (not well anchored) at this location. Several vehicles were damaged by flying debris. Minor roof damage occurred to other homes on 84th, 85th, and 86th Streets. On 87th and 88th Streets near Harvey, several homes suffered major roof damage and the western one-half of the New Life Baptist Church was destroyed. A portion of the church roof was thrown southeastward across 88th causing major damage to a home. Failure of the north, west and south walls of the church occurred as the roof lifted off.

This tornado touched down 1 block west of north May Avenue and Pembroke Terrace and moved east to Woods Park in Nichols Hills. Total path length was 1.5 miles and maximum width was 75 yards. This tornado was rated F2(113-157 mph). Four persons were injured and transported to local hospitals. Considerable damage was done to the strip mall in the 7400 block of north May Avenue. Windows were blown out of several businesses, several lost roofs, power lines were downed and large signs were bent. One business on the east side of May Ave. suffered collapse of an exterior south facing wall. On Pembroke Terrace, an RV was thrown into a house, a car was over-turned, trees were toppled, and shingles and roof decking were partially blown away. Lesser damage occurred eastward into Nichols Hills. Interestingly, this tornado rotated anticyclonically. Although the over-turned car and major damage to one wood frame house roof suggested the tornado may have reached F2 intensity in a very small area, the majority of the damage was consistent with an F1 rating.

This tornado was the most intense of the day. The tornado touched down approximately 1/4 mile southwest of the corner of Bryant Avenue and Hefner Road, and moved northeast crossing Interstate 35 at the Frontier City theme park parking lot. The tornado continued northeast along northeast 122nd Street and eventually dissipated 1/4 mile northeast of Interstate 44 at Douglas Blvd. The total path length was approximately 5 1/2 miles. Maximum width was 200 yards east of Interstate 35 and south of Interstate 44. The tornado was rated F2 (At 122nd Street approximately 1-2 miles east of I-35). Seventeen minor injuries (3 transported to hospital) occurred at Frontier City. Along the track, major structural damage occurred to businesses along Interstate 35 from 122nd Street southward for approximately three-quarters of a mile. The Frontier City theme park was among the hardest hit businesses. The tornado passed through the parking lot damaging numerous vehicles before striking a two-story concrete block building at the northeast corner of the park. This building suffered partial failure of external walls and the entire roof was removed. Damage to adjacent areas of the park was mainly due to strong inflow into the tornado.On the east side of Interstate 35, a Texaco truck stop was severely damaged. Empty semi-tractor trailers located in the east parking lot of the truck stop were over turned and rolled tens of feet. One trailer was briefly airborne and landed on another empty trailer. A small portable building containing a CB radio shop in the parking area was completely swept away into a grove of trees east of the lot. Numerous homes suffered major damage to roofs, windows, and garage doors in the Nottingham and Quail Ridge Run subdivisions located along 122nd Street 1-2 miles east of I35. Several homes suffered major or nearly complete roof failure, though most exterior walls remained intact. These homes were of recent construction and were well built with brick exterior facades (some likely in excess of $200K). No means of anchoring the roofs to the exterior walls was noted. The tornado may have approached F3 at times in these neighborhoods. The most severly damaged home was located atop a small hill with garage doors on the upwind side of the home. Debris patterns suggest the garage doors failed allowing the wind to lift the roof. Without the roof in place, failure of the external garage walls occurred. The most severe damage to trees occurred in these subdivisions and areas immediately adjacent.

Reported at 89th and Penn on the Oklahoma/Cleveland County line.
