.DISCUSSION...Today through Saturday.

On Monday, the next weather system will approach the region. The
trajectory of the moisture plume with this system will be more
typical - allowing the Sierra Nevada Mountain Range to rain-shadow
much of the Mojave Desert. That said, we`re still assessing the
potential for spillover precipitation to return widespread rainfall
chances to southeastern California, southern Nevada, and
northwestern Arizona. Pre-frontal snow levels will be slightly lower
than we experienced with our last system, ranging from 6500 to 7500
feet. Post-frontal snow levels will drop to around 5500 feet,
allowing for snowfall accumulations in more sensitive locations.
While the majority of snowfall will occur above 9500 feet, between 2
and 6 inches can be expected above 6000 feet. As such, issued a
Winter Weather Advisory for the eastern Sierra slopes, Inyo
Mountains, White Mountains, Spring Mountains, and Sheep Range. Due
to the potential for travel-impacting snow accumulations along State
Route 266 through Lida Summit, issued a Winter Weather Advisory for
Esmeralda / central Nye above 6000 feet as well. Elsewhere, expect
light-to-moderate rainfall with an isolated lightning strike
possible Monday and Tuesday. Afternoon high temperatures will drop
to between 8 and 10 degrees below-normal.

The region will experience a break from precipitation on Wednesday
before our attention turns to another weather system approaching the
region late-week. As mentioned in the previous discussion, changes
to the forecast track can have substantial impacts to the forecast,
resulting in low confidence at this time.

is expected in an arc from the Owens Valley across the southern
Great Basin and southward through Mohave County, where low ceilings
and reduced visibilities in rain and high mountain snow will
continue to be a concern. Elsewhere, expect prevailing VFR
conditions with areas of MVFR/IFR in scattered showers. South to
southwest winds gusting 15 to 30 knots can be expected over much of
the region today, settling down after sunset. VFR conditions are
likely areawide overnight before the next round clouds moves in
