Any idea what this is in Oklahoma?

Just saw this on scope. I don’t recall seeing this before. Something moving South in the middle of the screen.

And then by Indianola something appears to be moving in the exact opposite direction

It's a handful of reflected radials due to a stupid water tower immediately SSW of the KINX radar. See here: https://www.google.com/maps/@36.173...try=ttu&g_ep=EgoyMDI2MDQxMi4wIKXMDSoASAFQAw==

So what's happening in the loop you posted, to a rough approximation?

1. Within those few radials in the SSW sector, energy output by KINX leaves the radar and immediately hits the water tower
2. After hitting the tower, some of the energy reflects, so it propagates 180 degrees in the opposite direction (NNE)
3. The reflected energy finally hits storms NNE of the radar (somewhere around Nowata, it looks like). If you zoom out, you'll very likely be able to watch storm activity to the NNE of the radar mirror the general trend of the isolated bad radials you're focused on.
4. Energy is reflected by the Nowata storm back to the water tower, which then reflects back to KINX at the same incident angle it left from originally.

TLDR: in those specific sectors of KINX, you're always seeing a heavily-attenuated view of what's happening in the opposite direction from the radar.

Very frustrating that several Plains radars have nearby towers or other large objects that reflect the beam like this. KAMA is also notorious for having some radials SE of the radar reflect and travel NW of the radar instead.

Thank you. That makes a ton of sense!

And the absolutely unacceptable wind farm contamination at a number of sites, KDDC, KVNX, and KFDR are among the worst. At what point will this contamination get so bad it will make detecting mesocylones impossible? You have to wonder that eventually a tornado warming will not be issued that needed to be b/c of wind farm clutter.

What's worse, it's often an issue well away from the radar site, since wind turbine material is highly reflective, and the volume scans of the WSR-88D still will catch these turbines at a considerable range.
