27 May 2012 Kansas Shelf Cloud
This lapse features the tail-end of a mostly disorganized, messy line of storms in north-central Kansas. A pool of cold outflow induces a roll-shelf cloud hybrid. I.e., it starts out as a roll cloud detached from the parent storm, but then transitions to a shelf as the outflow generates new convection. Though difficult to see in the lapse, a shear funnel forms within the shelf near the telephone pole at 0.07s.
