See below at 22:13Z, at this time there were 18 detections from the NTDA algorithm.

Now before you go warning for a big bowing, comma-head shaped QLCS, taking a look at the velocity field below would show  the vast majority of these detection were due to mountainous terrain and stable airmass turbulence. Only 1 detection was due to a potentially tornadic circulation. You can probably guess which one that is by the probability icon color, but in the subsequent scan that probability was reduced to sub-50% and fell back into the rest of the noise. Generally, forecasters may be good at filtering these false detections out in a highly severe environment, but in mountainous areas where severe weather is rare, it may be something forecasters discard before an event ever occurs.
