A widespread damaging wind event occurred over a large portion of Oklahoma beginning late on the 9th and continuing into the early morning hours of the 10th. A stationary front located over southern Oklahoma was reinforced by an outflow boundary that moved south out of Kansas. Another stronger cold front moved from northwest to southeast through the northern half of Oklahoma. Thunderstorms developed over far southeast Oklahoma by late afternoon, moving off into eastern Oklahoma soon after. More widespread thunderstorms developed into northern and western Oklahoma with the strengthening of the low-level jet and aid from a well-timed jet streak moving overhead. The thunderstorms merged into a complex as they moved east. Severe wind gusts were reported from Roger Mills county in western Oklahoma to Hughes county in central Oklahoma. The most severe portion of the complex moved over northern Oklahoma, southern Logan, and southern Lincoln counties. Fairly widespread wind damage was reported over northern Oklahoma City. Later that evening, another complex of storms moved south out of Kansas into northern Oklahoma. A wind gust to 66 mph was measured near Ponca City. No damage was reported with the wind gust.
