Those are other radars operating on the same frequency. Maybe airplanes or ground stations. The waves crash into each other and give a false reading that there is something there. Observed this on a boat and thought they were aliens until I was informed by our radio guy what they were.

RF doesn't quite work that way. While interference can occur, each radar is base-lined to operate at a unique frequency within the 2-4Ghz range. Frequency managers have to obtain the operating frequency by making sure that a constant dissemination of a RF signal will not interfere with other RF signals.
Given also each radar has a tuned band pass filter on its receiver to only allow the transmitted frequency to be received.
This looks more like a back-end issue with the Radar Product Generator and its software algorithms. I will check to see if the NWS pushed an update around that time or had issues. Most of that is found in the public domain.
