   Areas affected...Central/Eastern/Northeast WY...Far Southeast MT

   Concerning...Severe potential...Watch unlikely 

   Valid 072034Z - 072230Z

   Probability of Watch Issuance...20 percent

   SUMMARY...An isolated severe threat will persist
   eastward/northeastward from central WY into eastern/northeastern WY
   and far southeast MT over the next few hours.

   DISCUSSION...A poorly organized thunderstorm cluster continues to
   move northward across into central WY. This cluster is moving along
   the eastern periphery of the stronger forcing for ascent attendant
   to the shortwave trough moving into the northern Rockies. Lead edge
   of this forcing appears to be delineated well by the increased
   cloudiness extending across western WY and back into northeast UT.

   This forcing for ascent will continue gradually eastward, helping to
   support the ongoing storms and promote additional development. The
   air mass is relatively dry, limiting instability and tempering
   updraft strength and persistence. Even so, enough buoyancy and
   forcing exist for continued development. Moderate vertical shear
   will contribute to some loosely organized structures capable of
   strong wind gusts and isolated hail. KRKS in southwest WY recently
   gusted to 44 kt. Expectation is for an isolated severe threat to
   persist eastward/northeastward from central WY into
   eastern/northeastern WY and far southeast MT over the next few
   hours.
