A discrete supercell tracked out of the Oklahoma Panhandle into southwest Kansas from 2120Z to 2220Z on 5/23/19.  During the first portion of this loop, the mesocyclone detection algorithms had a very difficult time latching on to one dominant meso, plotting up to four separate IDs for the same storm.  Eventually, both the legacy and new meso algorithms resolved one primary circulation, while the digital version continued to jump around a bit with the ID number and location.  For the last 15 min. of this animation, the MDA data completely dropped out.  The main point here is it was nearly impossible to utilize this product operationally because of the meso identification and data dropout issues.  It’s worth a mention that the legacy and new MDAs had about a 15-20 min. window of good meso tracking after the consolidation to one ID and before the data was lost. -Roy
