   The severe weather threat for Tornado Watch 461 continues.

   SUMMARY...A tornado and severe gust risk will continue with ongoing
   storms. The best chance for tornadoes will exist with low-topped
   supercells traversing a diffuse baroclinic boundary.

   DISCUSSION...Multiple low-topped supercells have developed and are
   traversing a diffuse west-to-east baroclinic boundary, where strong
   low-level shear is in place. The most recent ARX VAD shows a
   sizeable, curved hodograph and nearly 200 m2/s2 in the surface-500 m
   layer. As such, tornadoes and severe gusts remain a concern with the
   stronger storms, particularly with any low-topped supercells that
   continue to traverse the boundary, where maximum ingestion of
   streamwise vorticity may be realized.
