  through Monday, though any impacts should be minor.

* The chance of rain, snow, and wind impacts around Christmastime
  continues to increase.

.DISCUSSION...through Christmas Day.

Strong winds will continue across the Eastern Sierra as a shortwave
moves through the Pacific Northwest and the jet drops south. As a
result, a Wind Advisory remains in effect for the Eastern Sierra
through early Saturday morning. While widespread long duration
downslope winds are not expected in the Owens Valley, isolated gusts
in excess of 40 mph may occur in areas close to the foothills. In
addition to strong winds, the Eastern Sierra will also see a 20 to
40% chance of precipitation through the weekend into early next
week. Precipitation totals in the Eastern Sierra will range between
half an inch and an inch with locally higher amounts along the
ridgeline. Snow levels will be above 9,500 feet, which will restrict
winter weather impacts to the Sierra Crest. The northern portion of
the Owens Valley and the higher terrain of northwestern Esmeralda
County have around a 20 to 30% chance of seeing precipitation
over the weekend. Any precipitation will be light, as the Sierra
will block majority of the moisture from spilling over.
Elsewhere, dry conditions will continue through Monday along with
warmer than normal temperatures and southwesterly afternoon
breezes.

Unsettled weather will return to the region just in time for the
holidays as a trough digs along the coast, bringing an influx of
moisture to the region. Precipitation chances will begin to increase
across our western zones late Tuesday evening, spreading across the
region overnight. Precipitation chances linger through the end of
the week with the bulk of the precipitation expected to fall on
Christmas Eve and Christmas Day. Low elevation snow is not a concern
with this system as snow levels will be around 8,500 to 10,000 feet
across the Mojave Desert, with snow levels in the 6,500 to 7,500
foot range in Inyo County and the southwestern Great Basin
(Esmeralda and Nye Counties). Elevated southerly to southwesterly
winds will also accompany this system, with winds increasing on
Tuesday and remaining elevated through Thursday. Exact details
regarding wind speeds and precipitation amounts remain uncertain
at this time as there remains a wide envelope of possible
solutions. Regardless, the key takeaways should be that weather
impacts are growing more likely around the holiday. Those with
travel plans should be prepared for wet conditions on most roads
and wintry weather above 7-8kft.

.AVIATION...For Harry Reid...For the 00Z Forecast
Package...Most likely, winds will remain light and follow typical
directional patterns through Saturday. There is a low chance that
winds become southwest at 10KT this evening between 01Z-06Z, but
would then go back to west or southwest under 8KT after 06Z. Winds
will become light and variable Saturday morning before they
transition to a more northeast to easterly direction in the
afternoon. VFR conditions will prevail, with periods of high clouds
at or above 15KFT.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Low confidence in winds
at KBIH this evening as winds could be west or north to
northeasterly. Breezy winds at KBIH are also possible, especially if
the north or northeast winds set up. If elevated winds develop at
KBIH, they will diminish after 06Z and drop under 8KT before
potentially picking up again Saturday afternoon as speeds to 10KT
and a few gusts potentially set up again after 18Z. Elsewhere, winds
across the region will follow typical wind patterns, with speeds
generally 10KT or less through tonight. Light winds will continue in
most locations on Saturday except at KDAG where gusts up to 25KT are
expected in the afternoon. Precipitation is possible Saturday
afternoon in the Sierra with mountain obscuration possible.
Precpitation should not make it into the Owens Valley, though CIGs
may drop to 7000ft tonight. VFR conditions will prevail elsewhere
with CIGs remaining at or above 15kft.
