TORP Troubles with Extended Distances from Radars

During today’s real time case, one line of storms drifted off into the extreme northeast corner of our CWA (DMX). This corner reported meteorological echoes at about 150  km away (just shy of TORPs max effective range of 160 km). At the southern end of this line, a convincing hook signature with an admittedly broad mesocyclone caught our eye.

The long range line with hooking reflectivity and somewhat broad (but present) rotation.

Despite this, TORP was not creating any objects along this line with our selected radar (KDMX). Upon selecting the option to overlap other objects generated from surrounding radars, other objects appeared north of the hook in question, but not over it. This was a little concerning  as this the sort of feature I would expect to generate at least a low probability object. But this issue is not surprising considering the range away from any of the surrounding radars and how lofted the data is.

This issue will certainly pose a challenge in areas where there are large distances between nearby radars.
