What the National Weather Service wrote
Tornado D3 (McLoud tornado.) A tornado developed west-southwest of the intersection of Fishmarket Road and Memorial Road to the south-southwest of McLoud. The tornado moved east-northeast where a telephone company building lost it's roof, and a number of sheds were damaged and causing tree damage as it crossed the intersection and Fishmarket and Memorial roads. Extensive tree damage continued northeast of this intersection, at least one home suffered the destruction of an attached garage and a few homes suffered roof and window damage. The tornado turned north-northeast crossing Interstate 40 near the Walker Road bridge where it struck and semi truck, lifting and destroying the trailer, lofting the pieces to the north. The tornado dissipated soon after crossing Interstate 40. Although the tornado was very narrow, the rotational velocity of the tornado was observed to be very strong. Monetary damage estimates were not available.
The wider storm
A tornado outbreak occurred over parts of northern and central Oklahoma during the day on the 24th, with violent tornadoes devastating several communities. By the end of the day, one EF-5, two EF-4, and two EF-3 tornadoes destroyed buildings, ripped up trees and power poles, and unfortunately, resulted in 11 deaths. The day began with a strong upper level trough ejecting out of the southwest United States. The trough took on a negative tilt as it approached the southern Plains. A strong jet stream was located at both the middle and upper levels rotating around the upper trough. At the surface, a low pressure strengthened rapidly over northwest Oklahoma, keeping the low-level flow of warm, moist air to flow east of a dry line that had moved into western Oklahoma. Thunderstorms developed by early afternoon over western Oklahoma, and quickly became supercellular as they moved northeast. Strong low-level rotation developed early, with the first tornado occurring over Blaine county, and moved northeast into Major county. Another supercell rapidly gained low-level rotation as it moved from Caddo into Canadian County. This tornado became the strongest of them all as it moved north of El Reno, west of Piedmont, and to south of Guthrie in Logan county. Nine people died as a result of this tornado. Two more powerful supercells developed over Grady county, and they moved northeast into McClain and Cleveland counties. Finally, the final tornado occurred east of Norman into Pottawatomie county. The timing of this outbreak could not have come at a worse time, as rush hour was just unfolding as the tornadoes neared the Oklahoma City metro area.
Began near Dale (35.3730, -97.1310).
