LOT/GRR Real Time Case

KIWX has spurious outbounds behind the higher reflectivity that do not appear to be associated with organized storm-scale rotation, given it’s placement and also very high spectrum width. 33% prob TORP seems to be associated with this artifact.

Noticed that two TORPs along the leading edge of the line jumped to a common circulation but did not merge. One was from KMKX and the other was from KLOT. Ideally, these would have merged and the TORP from the closest range radar would have taken over.

UPDATE: Found “Display Overlapping Options” filtering option, which when turned off shows objects from all radars. Curious how this filtering decides which to display when turned on? Higher probability? Closer range? Longest track duration?

Although insignificant and not worthy of a Tornado Warning at this time, it’s noteworthy that TORP did call my attention to an area of a storm cluster where I would not have heavily interrogated the velocity. Rotation is weak but is present and TORP flagged this, calling my attention to it. This demonstrates at the very least the situational awareness utility of TORP.  Noticed this in AvShear, too.

The difference in the rotation between KGRR and KIWX doesn’t seem to necessitate that difference in probabilities for the objects associated with each radar. 48% vs 90%. Upon going back to look at this again, I only see GRR and not IWX. So filtering must have purged IWX, although in real time they were both visible.
