This ended up being one of those very local chases. I actually slept in anticipating a busy period later that night with covering weather in Texas. I woke up to find a storm developing about 40 miles to my south. That storm was approaching a warm front and was showing signs of becoming organized in the low levels. Gas was cheap so I figured it wouldn’t hurt to take a quick drive to check it out. By the time I arrived near the storm it had moved to about 10 miles southwest of Purcell, Oklahoma. The National Weather Service issued a Tornado Warning not long after. The storm had a very low base thanks to its proximity to the warm front. A rotating wall cloud was visible to the southwest of Purcell. Other storm chasers reported a brief tornado but I was unable to confirm it from my position. I observed strong rotation as the storm moved over Purcell itself. The storm did produce at least one brief tornado just east of the Canadian River and east of Purcell which I observed from the Canadian River Bridge. A traffic accident had the bridge blocked so I was unable to pursue the storm from there. Fast forward about an hour and we were east of Norman, Oklahoma. Storms weren’t particularly intense but there was a considerable amount of low-level vorticity. We were able to observe a very weak, brief tornado from a thunderstorm approaching Interstate 40 west of Shawnee. From there we headed back to Norman and just south to Noble, Oklahoma to document flash flooding.
