Rear Flank Gust Front

Rear Flank Gust Front

As so often happens, a late May afternoon on the Great Plains brought a colorful and dynamic sky of clouds and storms. A somewhat high-based supercell cruised past us to the north, painting this sky scene. The mesocyclone, which was located behind the lower right part of the curving shelf cloud, didn't look too dangerous at that point, and to nobody's surprise, the storm was spewing a rather large load of outflow. Invisible at ground level, the rear flank gust front aloft was marked by the shelf. Somehow, the storm wouldn't undermine itself with cold air until after it got better organized for a little while.
