A stationary front across northeastern Oklahoma and southeastern Kansas resulted in multiple rounds of thunderstorms across the region from June 26th through June 30th. Four to eight inches of rain fell across much of Ottawa County during the early morning hours of June 26th, with heavy rainfall also occurring across the Neosho River basin in eastern Kansas. Six to twelve inch rainfall amounts occurred in a 3-day period ending during the mid morning hours of June 28th. This widespread heavy rainfall resulted in moderate flooding along the Neosho River near Commerce, which continued into early July.
The frontal boundary pushed southward into northeastern Oklahoma on July 1st, with another round of thunderstorms developing during the early morning hours. This activity continued into the evening. Unusually high precipitable water in the atmosphere promoted additional heavy rainfall from these thunderstorms. Widespread two to six inch rainfall amounts occurred across northeastern Oklahoma, which resulted in flash flooding. The Deep Fork River near Beggs experienced major flooding as a result of a week's worth of rainfall totaling up to around ten inches in the basin.
