Interesting radar imagery

Don't think I've seen this effect before, guess it has something to do with the heat. It's certainly not rain!

Is that the RS app and if so, what view are you using?

It's my little nexrad app. Click the link in my post above...

But, yes, it is also visible in RadarScope with the Super-Res Reflectivity setting.
