Severe thunderstorms developed over central Oklahoma and southern Kansas along a slow-moving cold front during the afternoon hours of May 31st. Very unstable air ahead of the cold front, combined with strong wind shear, resulted in storms quickly evolving into supercells. These storms produced several tornadoes during the evening hours across northeastern Oklahoma. Severe weather and heavy rain continued into the morning hours of the 1st as the storms slowly moved through the region.
