   Areas affected...Western Pennsylvania

   Concerning...Severe Thunderstorm Watch 394...

   Valid 260043Z - 260145Z

   The severe weather threat for Severe Thunderstorm Watch 394
   continues.

   SUMMARY...The threat for severe storms will continue to diminish
   slowly through early tonight, and the watch can likely be canceled
   by about 01-02z.

   DISCUSSION...With the loss of daytime heating, low-level static
   stability has already begun to slowly increase from PA into OH as
   surface temperatures cool.  Widely scattered thunderstorms are still
   ongoing in an environment with sufficient vertical shear for
   supercells, but the storms are expected to slowly weaken and become
   rooted slightly above the surface with time.  The overall severe
   threat has become marginal and the watch can likely be canceled by
   01-02z.
