As we move along through this case, east of the convective line exists a plethora of potentially potent supercells; each is producing high values of AzShear from multiple radars as well as in the merged products.  But what about further back west with the incoming convective line that is looking a little QLCS-ish?  Here is an example of how three products can be used together to help determine areas of increasing potential for rotation.

First, from KEOX:

A broken line of storms has an area of enhanced inbound velocities with a stronger storm in the line (just south and east of the target/bulls-eye/red and white marker).  The single-radar AzShear shows cyclonic shear all along the leading edge of the line but with an enhanced area of shear along a small bowing segment.

Now take a look at KMXX AzShear (with the velocity and reflectivity staying with KEOX):

Only 1 minute 30 seconds after the KEOX scan, this shows what will likely be an area of rotation higher up in the storm (2.5 km up from KMXX vs 1.2 km up from KEOX using the beam sampling tool) so there is something aloft as well.  O.K….thinking along the lines of mid-level rotation above a strengthening area of shear at the lowest tilt; interesting.

Finally, looking at the merged 0-2km AzShear (again with the velocity and reflectivity products remaining at KEOX):

Yup, there could be something there BUT the big caveat is that you don’t want to get caught thinking that this feature has a long “history” since that trail extends south and west from our area of interest.  Nope, that’s the shear along the leading edge of the convective line.  However, it does show that the strongest AzShear values are close to our marker/area of interest so id doe need to be watched for future potential strengthening…(post-note: nothing was reported/observed tornado track wise)
