Mesoscale Discussion 1326

   Areas affected...Southwest ID

   Concerning...Severe potential...Watch unlikely 

   Valid 232300Z - 240030Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated severe wind and marginal hail will be possible
   through about 02Z across parts of the Snake River Valley.

   DISCUSSION...Strong to locally severe convection is ongoing across
   far southwest ID. This activity appears to be tied to a subtle MCV
   that is slowly moving east-northeast. 20-25 kt mid-level
   southwesterlies per the CBX VWP in conjunction with surface
   temperatures still holding around 90 F will be supportive of
   isolated severe wind gusts as small multicell clusters evolve across
   portions of the Snake River Valley. The strongest updrafts will also
   pose a risk for marginally severe hail. These threats should wane
   later this evening as convection eventually spreads towards the
   Sawtooths.
