Watching the MCS evolve over Indiana, ProbSevere became increasingly hard to use. The object continued to change in size and in number, so it was hard to trust the probabilistic values. Ideally, I would have liked to see one on the eastern flank where the strongest velocities were, another on the western flank where the reflectivity is higher, and perhaps one or two more in between.  However, since the orientation of the MCS continues to change, I’m not sure if that would continue to be the preferred object count and location.  Bottom line is to use ProbSevere with caution with lines, bows, MCS’s or anything with ill-identifiable cells.
