The combination of a surface cold front and weak upper level shortwave initiated showers and thunderstorms across the eastern Oklahoma Panhandle during the evening hours of the 8th. At 3 PM CST, the surface cold front had begun to slow as it moved into the western Oklahoma Panhandle. The lift provided by the front had proved sufficient in initiating scattered thunderstorms along the front from northern Kansas to the southwestern Texas Panhandle. However, it was not until the mid-level shortwave approached the area around 6 PM CST that these thunderstorms strengthened sufficiently to produce severe level hail over the eastern Oklahoma Panhandle. By this time, the cold front was stretched from the north central Oklahoma Panhandle to the northwest corner of the Texas Panhandle. As the evening hours progressed, the surface cold front stalled across the eastern Oklahoma Panhandle however, thunderstorms were able to advance to the south-southeast out of the Oklahoma Panhandle by 7 PM CST.
