A long day of driving up from Norman, and observing spectacular supercells mainly in Nebraska, concluded on the way to my motel room at night, with another one forming along a trailing part of the same outflow-reinforced baroclinic zone. Staring straight under the mesocyclone and wall cloud here, with a formidable rear-flank core at left, and given the stabilizing inflow layer, I knew this storm would have a limited window to produce a tornado, if at all. The synoptic to mesoscale environment was only marginally favorable, yet this mesocyclone tried hard, drawing up convergent dust columns from both the inflow region (right) and rear-flank gust front (left). Cloud-base cyclonic shear was broad and not very strong, however, as ascertained by following individual lowerings through nearly continual in-cloud lightning, and the dust was rising and converging far more than rotating (if at all). Verdict: nontornadic! Regardless, the mesocyclonic updraft was moving my way, and still obviously surface-based, compelling me to get out of its way shortly.
