   The severe weather threat for Severe Thunderstorm Watch 419
   continues.

   SUMMARY...Gradually diminishing storm strength and coverage is
   anticipated over the next few hours.

   DISCUSSION...Widely scattered severe thunderstorms are currently
   ongoing across the central High Plains, supported by modest
   instability and moderate vertical shear. Most storms have quickly
   become outflow-dominant, leading to somewhat short updraft
   persistence. The only exception thus far is the storms across Morgan
   and Logan Counties in CO, where slightly more organization has
   allowed for upscale growth along the outflow. This organization
   could allow for the severe threat to persist downstream for longer
   than has been observed within the more cellular activity. Overall
   expectation is for convective inhibition to gradually increase over
   the next several hours, which will lead to diminishing cellular
   severe storm coverage. In contrast, longer life cycle of the linear
   segments is anticipated, particularly if these lines can be persist
   long enough to realize the augmented warm-air advection provided by
   a strengthening low-level jet.
