   Areas affected...Southeast OR into southwest ID and extreme northern
   NV

   Concerning...Severe potential...Watch unlikely 

   Valid 092328Z - 100130Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated hail and severe gusts are possible into early
   evening.

   DISCUSSION...Scattered thunderstorms are ongoing across southeast OR
   and vicinity, in advance of a shortwave trough moving across the
   Pacific Northwest. MLCAPE of up to 500 J/kg and moderate deep-layer
   shear are supporting occasionally organized storm structures, with a
   couple of stronger cells noted across Malheur County, Oregon. Those
   cells will eventually encounter stronger MLCINH to the northeast,
   but isolated hail and severe gusts will remain possible in the short
   term. Other less-organized convection is ongoing farther west into
   south-central OR, and also moving out of far northern NV. A stronger
   cell or two could develop across those areas as well, but even the
   ongoing less-organized convection could pose a threat of isolated
   strong to severe gusts, especially where the environment remains
   rather warm and well mixed.
