The Wall Cloud Wall
Peering northward from under one of the many trees in southeastern Oklahoma, we watched the last mesocyclone of this previously tornadic supercell cut its clear slot and occlude, not to produce any more spinups. Still, we had to wait several minutes for this circulation to clear the northward road that would take us to the Ada supercell. The old Hickory/Sulphur storm shown here had moved too far over an old outflow boundary, ingesting progressively more stable air with time, and weakening in a moist but cool environment. The orange light under the wall cloud was arriving from behnd and beneath the anvil of the Ada storm at around sunset.
