May 2nd showed great promise from the eastern Texas panhandle across western and central Oklahoma. Good shear, moisture and instability would be found and a sharp dryline would provide the convergence necessary to initiate intense supercells. Clusters of storms formed first in southwest Kansas at the triple point, while numerous storms formed a touch later down the dryline. One storm we targeted was severe just northeast of Shamrock, Texas. We were quick to find out the failure mode this day and that would be too many cell mergers, splits and interactions. This first storm had merger issues and never got to what it could be. So, we targeted a new cell to our south that became tornado warned off and on for several hours. As the storm moved east to Binger, OK, it cycled several times and had great structure. It tried to produce but just couldn’t focus long enough to get a tornado down. The lightning on the cell was intense at times and occasionally wouldn’t allow us out of the vehicles. Soon, as models suggested, a long line of storms formed and became a wind producing machine as they marched across Oklahoma, with mesovorticies occasionally developing along the leading edge.
