Looks like one of the NEXRAD weather radar sites was malfunctioning.
Looks neat! 
Whats up with the two airplanes towards the east that have “waggy” tails?
Looks like a Flagellum …among other things.
Probably two radar sites seeing the aircraft in slightly different positions.
I saw something very similar around LAX last week. It appeared at all ranges (national map, local map, etc.) but disappeared while I was playing with it trying to see more. Jan / Iowa
Perhaps the flights from the east are sperm donor flights.
Yeah, I vote radar malfunction or test and you can see where it’s doing a sweep and “fixing the glitch.” Looks pretty cool if you ask me.
