   Areas affected...Southern Idaho into southwest Montana

   Concerning...Severe Thunderstorm Watch 468...

   Valid 270051Z - 270245Z

   The severe weather threat for Severe Thunderstorm Watch 468
   continues.

   SUMMARY...Storms will remain capable of severe winds and marginally
   severe hail into the evening. The environment becomes less favorable
   to the east and a weakening trend is expected as storms move into
   southwest Montana.

   DISCUSSION...Scattered convection continues across parts of southern
   Idaho and will eventually progress into southwest Montana. With the
   continued approach of the upper-level trough this evening, some
   additional development remains possible in western Idaho. The most
   intense storms will continue to pose a risk for severe winds as well
   as marginally severe hail. The hail threat should generally be
   modulated by somewhat limited buoyancy. With temperatures cooler and
   the airmass drier into southwest Montana, storms are expected to
   gradually weaken with eastward extent.
