Widespread and locally heavy rainfall occurred from the 26th through the 30th across much of eastern Oklahoma. A slow-moving storm system over the southwestern United States and a nearly stationary frontal boundary over the region resulted in several rounds of widespread rain and isolated thunderstorms. Near record precipitable water values were observed as gulf moisture spread into the area in the lower levels of the atmosphere, and moisture associated with a tropical system over the southeastern Pacific Ocean spread into the region in the middle and upper levels of the atmosphere. Rainfall amounts ranged from around three inches in portions of northeastern Oklahoma to between eight and ten inches in southeastern Oklahoma.
This excessive rainfall, combined with soils that were already quite saturated, resulted in flash flooding and flooding. Several main stem rivers flooded, including the Neosho River near Commerce and the Kiamichi River near Antlers, which both experienced moderate flooding.
