Correlation between Single-Radar Az Shear and a TDS?

A tornadic debris signature was noted during this event with a loop (not shown) of low CC values, with depth,  coinciding with a strong velocity couplet and high Single-Radar AzShear values. Is there any correlation to a TDS signature with Single-Radar AzShear values? To be determined…
