Thunderstorm Wind in Jackson County, Oklahoma

Numerous large tree limbs were downed around town. Monetary damages were estimated.

An unusually strong storm system entered the northwest United States and moved southeast toward the Four Corners region. Surface low pressure developed over southeast Kansas and deepened rapidly. Surface winds over Oklahoma also steadily increased, with sustained winds of 30 to 40 mph and wind gusts over 50 mph reported at times. These non-thunderstorm winds caused some minor damage throughout the day. By mid afternoon, the storm system had moved toward the plains, with widespread thunderstorms developing from South Dakota into northern Texas. Over Oklahoma, thunderstorms developed along and east of a dry line that was located near the Oklahoma and Texas panhandle border. The thunderstorms took some time before becoming severe, but due to the degree of instability and wind shear farther to the east, supercell thunderstorms finally emerged. Damaging wind gusts and large hail occurred as the storms moved northeast at 45 to 60 mph. Numerous wind gusts of over 80 mph were reported, with many locations reporting wind damage as the thunderstorms passed. Heavy rainfall also occurred, with some locations receiving 3.50 to 4.50 of rain. Several roadways had to be closed due to water running over them. Monetary damages were estimated.
