Here’s a series of screenshots showing how both algorithms increased detections and intensity as the event evolved.

After a difficult start to this event in which both algorithms had an absence of detections despite multiple reports of tornadoes and funnel clouds (likely due to very limited Z in the area of weak rotational couplets), both algorithms performed much later in the event when two dominant supercells emerged as the primary threats. Both algorithms showed an increase in intensity coincident with increasing rotational velocity, and for the most part, tracked these features well.

It’s good to see these algorithms do well in relatively obvious situations, because if they can’t get these right, it’d be hard to use these operationally with much confidence.
