.KEY MESSAGES...

* Gusty winds, light-to-moderate rainfall, and mountain snow
  expected in the higher elevations of the southwestern Great Basin
  through Monday.

* Mid-to-late week, widespread rainfall, isolated instances of flash
  flooding, high-elevation snowfall, and gusty winds will impact
  Christmas travel.

.DISCUSSION...Today through Friday.

Latest high resolution guidance continues to highlight the potential
for strong gusty downslope winds off the eastern Sierra slopes and
into the northern portions of the Owens Valley on Sunday. There is a
50-70% chance of gusts exceeding 40 mph in Bishop, Big Pine, and
across Highway 395, as well as a 60-70% chance of gusts exceeding 58
mph in the eastern Sierra including Aspendell. As a result, hoisted
a Wind Advisory through the day on Sunday for these two zones.
Otherwise, continuing to see the potential for precipitation
isolated to the higher elevations of the southwestern Great Basin.
Sierra spillover will be limited, though Aspendell can expect
between 1 and 3 inches of fresh snowfall, with Mt. Whitney expecting
around 1 foot. Elsewhere, spillover will simply look like increased
cloud cover. Above-normal temperatures continue, with additional
daily records in jeopardy (see CLIMATE section below).

On Tuesday, gusty south winds will pick up in the southern Great
Basin, with gust speeds generally 25 to 35 mph across northern Inyo,
Esmeralda, and central Nye counties. Gusty south winds spread across
the forecast area on Wednesday, with widespread chances of Wind
Advisory-level speeds (40-60%). Gusty winds linger into Christmas
Day before speeds fall off heading into the weekend. Regarding
precipitation, the first push of moisture will move into the region
late-Tuesday, will have subtropical origins (with snow levels
exceeding 9000 feet), and will saturate the atmosphere column.
Forecast PWATs range from 0.80 to 1.10 inches across the forecast
area, which will couple with orographic lift to produce the
potential to drop over an inch of measurable rainfall across area
mountains. Sierra spillover moisture will combine with this
subtropical moisture plume, resulting in the greatest forecast
precipitation amounts existing across Inyo and western San
Bernardino counties Tuesday night through Wednesday. While
confidence is high that the entire forecast area will observe
measurable rainfall, the confidence in exact amounts remains low at
this time, with 5-15% chance of flash flooding across the Mojave
Desert. The second round of moisture impacts the region after
Christmas and will be accompanied by a drop in PWATs to between 0.50
and 0.75" and snow levels dropping to 5000-6000 feet, which will
allow area mountains to receive fresh snowfall.

.AVIATION...For Harry Reid...For the 00Z Forecast
Package...High confidence that light winds following typical
directional patterns will continue through Sunday morning.
Confidence in the wind forecast then decreases Sunday afternoon.
Winds will either become gusty out of the southwest after 21Z or
they will continue to be light out of the east or northeast. If
there is significant cloud cover Sunday, the lighter winds will be
more likely...however if there is more sun then gusty winds over
20KT should develop. The confidence in the wind forecast remains low
into Sunday evening as winds become south or southeast after 00Z but
uncertain how strong they will be. 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...Gusty west winds in the
Western Mojave Desert and KDAG will continue through sunset, then
winds will diminish overnight and light winds are expected on
Sunday. Elsewhere, winds this evening and overnight will follow
typical light wind patterns. On Sunday, low confidence in winds at
KBIH as southeast or east winds Sunday morning will either become
gusty out of the northwest or continue to be southeast at 10KT.
Elsewhere, winds across the region will become west to southwest in
the terrain with gusts 20-30KT, but light winds will continue in
most valleys. SCT-BKN at or above 15kft will continue to stream
across the region. &&
