.DISCUSSION...through Saturday.

Weather during the first half of the week will continue to be
characterized by the dry conditions and warmer than normal
temperatures that dominated the latter half of October as we
continue to find ourselves under an upper-level ridge. A weak cut-
off low will drift inland, lifting through southern Nevada Sunday
night into Monday. The only noticable impact from this system will
be increased mid-to-upper-level clouds for the southern and
eastern portions of our forecast area.

A shortwave trough will move through the Great Basin during the
middle of the week, bringing a 15 to 30% chance of precipitation to
the crest of the eastern Sierra on Wednesday. Precipitation totals
will be less than a quarter inch, with a dusting of snow possible
in the higher terrain. This shortwave will also bring gusty winds
to portions of the region. Overall, wind gusts are expected to
remain sub-advisory (less than 40 mph) for most of the region. The
exceptions to this are the Sierra crest, the northern Owens
Valley (especially near the Sierra foothills), and Highway 95
between Indian Springs and the State Route 160 junction where
chances for peak gusts in excess of 40 mph on Wednesday are 50% or
greater. This system will also result in temperatures decreasing
around 3 to 6 degrees from Tuesday to Thursday as it knocks 500 mb
heights down. 500 mb heights are expected to rebound going into
the weekend as the upper-level ridge attempts to reestablish
itself over the Southwestern United States.
