Areas affected...Southwest Utah...northwest Arizona...and southern
Nevada.

Concerning...Severe potential...Watch unlikely 

Valid 252336Z - 260130Z

Probability of Watch Issuance...5 percent

SUMMARY...Cluster of storms may pose a severe wind threat as it
continues southwest.

DISCUSSION...A cluster of cells has developed in southwest Utah and
started to accelerate southwestward. The environment downstream of
this activity is unstable with MLCAPE around 1000 J/kg per SPC
mesoanalysis. Mesoanalysis also shows increasing CINH across this
region which may limit the overall severe threat. However if this
cluster can maintain intensity, it may pose a severe wind threat as
it moves southwestward over the next couple of hours into an area
with DCAPE of 1400 to 1700 J/kg.
