   Concerning...Severe potential...Watch possible

   Probability of Watch Issuance...40 percent

   SUMMARY...Thunderstorms are expected to persist across
   northern/northeast UT into southwest WY and far southeast ID over
   the next few hours. The strongest storms could produce hail and
   strong wind gusts.

   DISCUSSION...Observations reveal that lightning activity in the
   cluster of storms moving across north/northeast UT has increased
   over the past hour. This increase in likely a result of updrafts
   strengthening/deepening amid both persistent forcing for ascent and
   modest destabilization from increasing mid-level moisture and
   daytime heating. Downstream air mass across far northern/northeast
   UT and adjacent southwest WY remains relatively cool but the strong
   forcing for ascent and daytime heating should still result in
   persistence of the ongoing cluster. Some additional development
   farther back northwest into far southeast ID is also possible.

   Buoyancy will remain limited throughout much of the day, potentially
   leading to somewhat transient updrafts. Even so, the strength of the
   mid-level, and resulting strong vertical shear, will result in the
   potential for a few organized storms capable of hail and strong wind
   gusts.
