After peaking in width, the Canadian (TX) tornado gradually narrowed but still presented a stout appearance at this stage. Tornado size does not necessarily offer any insight into intensity. In fact, assuming the mass flux through the vortex changes little or none, a tornado can strengthen as it narrows, due to conservation of angular momentum. Because this tornado occurred mostly over scrubby, open country and mainly affected a cluster of oilfield equipment, true intensity changes along its path likely will never be known. Soon a loop vortex would spin up in the sky almost overhead, while this tornado still churned along.
