A surface low pressure system was positioned over southwestern Kansas during the evening of the 5th, with a stationary frontal boundary extending southeast from the low into northeastern Oklahoma and northwestern Arkansas. Thunderstorms developed over northwestern Oklahoma and south central Kansas during the evening hours and moved east into northeastern Oklahoma during the late evening hours of the 5th and early morning hours of the 6th. The thunderstorms evolved into a nearly solid line by the time they reached northeastern Oklahoma and resulted in widespread damaging wind. Very strong low-level wind shear ahead of the line allowed for the development of several areas of rotation along and within the leading edge of the thunderstorms. Several tornadoes formed from these low-level circulations, including a strong tornado that resulted in severe damage across portions of the City of Tulsa.
