What the National Weather Service wrote
This tornado moved into southern Harmon County from far western Jackson County. Utility poles were snapped along and just north of the county line along State Highway 5.
The wider storm
An intense (90-knot) mid-level jet streak lifted from the Texas Big Bend region into the Southern High Plains early on the 18th. An extensive quasi-linear convective system (QLCS) took shape across West Texas and moved into portions of western Oklahoma and western-north Texas during this time. With anomalously strong kinematics and marginally sufficient wind shear, a few portions of the line produced reports of thunderstorm wind damage and multiple brief/weak tornadoes. With time, the convective system gradually weakened into portions of central and eastern Oklahoma, producing only sporadic wind gusts/damage by daybreak.
Began near Gould (34.5070, -99.7720).
