We continue to see significant issues with ProbTor that seems directly related to inflated Low Level AzShear values. This is likely due to an outflow boundary that is extremely well sampled by the KBIS radar.  As this outflow boundary races ahead of convection, the actual tornado threat, which was never high to begin with, continues to drop even more.

ProbTor, on the other hand, places a tremendous amount of weight on LL AzShear,  resulting in a persistently high ProbTor values.
