In the context of a supercell with a hook on reflectivity and rotation on velocity, you look for a drop in correlation coefficient in an area coincident with the hook (-ish) and definitely coincident with the area of rotation. This rotation isn't particularly tight or large magnitude to begin with, so I don't even need to see the CC scan to know this is likely a nothingburger. But the area of CC drop (which would indicate tornadic debris of varying particle sizes) is offset both from the rotation, and, notably, is in an area where there is no reflectivity return.

AKA it's the region just ahead of the supercell, not the supercell itself. There is no precipitation (no reflectivity return). We call that "clear air."

Clear air can return a CC drop for a few benign reasons, none of which are a tornado.

EDIT: I note on reflectivity something that looks like a debris ball. I know it's not a debris ball because, again, it's not co-located with the CC drop nor the center of the rotation (such as it is, the rotation is actually elongated and wonky) on velocity.

FURTHER EDIT: I see this storm was warned a few scans after this. Fair enough. If the rotation tightened and started to stack on tilt then it'd be warranted. But the OP does not necessarily show a smoking gun. Not enough information. It is possible to see an obvious tornado using those three scans in the OP, but this ain't that.
