Rotan LP Wall Cloud

Rotan LP Wall Cloud

(Part 1 of 3)... Sample the evolution of a closeby, rotating wall cloud in an LP (low-precipitation) supercell. Tiered inflow tail structures give this wall cloud a double-decker appearance. A difluent rain foot (and possible microburst) is visible at lower right, N of the mesocyclone. The chunk of scud in front of the wall cloud (upper foreground) was moving left-to right; while cloud tags on the rear of the wall cloud were moving right-to-left. This indicated cyclonic low-level rotation -- and a need to keep a close watch on this thing! Rotation became even more evident as the wall cloud moved closer...
