First thing I realized when analyzing AzShear side bye side with Velocity is that the AzShear feature catches the eye much better than a weaker rotation signature in Velocity. Here is an example:
If a forecaster was looking at a lot of activity going on around the CWA, a weaker velocity signature can be missed, but AzShear jumps out with the high (white) values. This circulation went on to strengthen quickly and to me the AzShear did a better job at showing that earlier in the tornadoes life.
Another example, also involving TORP: Focusing on the weaker circulation in the following images, which is outlined by the TORP circle that is farther southwest. 0.5 Velocity again shows a weaker rotation that could be overlooked. That same scan though, AzShear is lit up along with TORP of 48%. This allowed me to look closer at that feature and I found a weak echo region and a higher reflectivity core aloft. Once again showing AzShear and TORP are good for situational awareness.
