   Areas affected...portions of southeastern Idaho and northern Utah

   Concerning...Severe potential...Watch unlikely 

   Valid 292014Z - 292115Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated strong to severe wind gusts possible with
   thunderstorm activity this afternoon.

   DISCUSSION...Widely scattered thunderstorm activity is expected to
   develop this afternoon across portions of northern Utah into
   southern Idaho. Daytime heating has yielded temperatures in the
   upper 80s to 90s F and large dew point depressions, with dew points
   in the upper 40s to low 50s F. Steep lapse rates and sufficient
   MLCAPE around 500 J/kg amid deep layer shear around 30-40 kts may
   support isolated more organized cells with potential for strong to
   severe gusts. Overall, the coverage of organized storm potential is
   expected to remain low and a watch is unlikely to be needed.
