As the cell continued to grow, it merged with the warm front to the north 
but maintained a fairly pronounced structure with strong rotation and strong
updraft into the mesocyclone.
Mammatus were forming directly overhead, scud clouds were rapidly 
rotating around the mesocyclone and there were several attempts to
build a funnel downward from within the wall cloud.
Off to the south, another developing thunderstorm got our attention.  Noting that 
the storm in front of us appeared to be weakening and moving into the cold air 
to the north of the warm front, we chose to pursue the developing cell off to the south.
