Mesoscale Accident

Jim LaDue provides an interesting perspective to the 29 May 2012 tornado event northwest of Oklahoma City. As he states: "Meteorologists often refer to a mesoscale accident in the context that tornadoes can occur even when the environment surrounding the storm is unfavorable for their occurrence. On 2012 May 29, this is what happened when a gust front from a left-moving supercell to the south collided with a right-moving supercell dropping southeast from Kingfisher, OK. The result was tornado genesis. This video shows the base of the right-moving supercell start to rapidly rotate and start to wrap precipitation around the center. The tornado revealed itself just after the end of this video."  My blog entry on this event is here.
