Area Forecast Discussion
National Weather Service Las Vegas NV
1009 AM PST Mon Jan 9 2017

.SYNOPSIS...The tail end of a Pacific storm will continue to
push across Arizona with most areas seeing dry conditions by late
afternoon. Mainly dry conditions expected Tuesday before another
storm system brings widespread rain and snow to the southern Sierra
Wednesday. Unsettled weather can be expected through Friday as
additional Pacific systems move into the West Coast.
&&

.UPDATE...The sparse precipitation band moving over far southeast
California into Arizona will continue moving to the east and that
will be the end of showers for most zones. Runoff impacts from the
moderate to heavy rain in the southern Sierra and Owens Valley
overnight appear to be minimal according to local officials and the
Flood Watch will be cancelled. Minor adjustments will be made to the
POP/WX/Sky/Wind grids for the rest of today to reflect the latest
trends. Southwest winds gusting 30-35 mph can be expected across
much of the Mojave Desert zones through the afternoon. The rest of
the forecast trends detailed in the previous discussion look good
and attention will turn to the potential for significant snow in the
Sierra and possibly the Owens Valley late Tuesday into Wednesday
with the next Pacific Storm.
&&

.AVIATION...For McCarran...Southwest winds gusting 25-30 kts can
expected through the afternoon. Mainly sct clouds aoa 10k feet this
afternoon. Mechanical turbulence can be expected through late this
afternoon.

For the rest of southern Nevada...northwest Arizona...and southeast
California...Sct showers will move across northwest Arizona through
early afternoon with cigs down to 5-6k feet at times. Gusty
southwest winds can be expected across most areas with speeds of 20-
30 kts.
&&

.PREV DISCUSSION...
410 AM PST Mon Jan 9 2017

.SHORT TERM...through Wednesday afternoon.

Deep plume of tropical moisture has shifted south overnight with the
main plume being directed into Los Angeles and Orange Counties with
moisture spreading into western portions of San Bernardino County.
This trend is expected to continue for the next few hours with
rainfall spreading across the remainder of San Bernardino, Clark and
Mohave Counties. Rainfall amounts are generally expected to be up to
a quarter inch over San Bernardino County with lower amounts over
Clark and Mohave Counties. A few thunderstorms have also popped up
near the coast so its possible that we may see a lightning strike or
two over our western areas early this morning. This moisture plume
will continue to drift south this morning with most areas seeing
drying conditions after noon. Snow levels will remain fairly high
with the current freezing level just above 10k feet. Rainfall
amounts and intensity will decrease over the next couple of hours
across the Sierra with mainly just light scattered showers left this
morning. Did extend the Flood Advisory for the Sierra and Owens
Valley through 6am and the current Flood Watch is still in effect
until 4pm this afternoon. Even though the heaviest rain will end,
significant runoff is still likely through this afternoon.

Dry conditions expected tonight through much of Tuesday, but another
round of moisture is expected to reach the southern Sierra by
Tuesday night. The upper low that has been hanging off the Pacific
Northwest coast will gradually shift south and east bringing
moisture back into the southern Sierra Tuesday night and across
portions of Esmeralda, central Nye, and Lincoln Counties. Unlike the
previous systems, this system will be colder and snow levels will be
lower. Snow levels look to drop to around 6000-6500 feet by Tuesday
afternoon and then down to around 4000 feet over northern Inyo
County by mid day Wednesday. Snow levels will be around 5000 feet
for Esmeralda, central Nye and Lincoln Counties, but snow amounts
over those areas will be much lower. There could be a few showers
pushing into southern Nevada and northwest Arizona, but shower
should be more widespread and generally confined to the mountains.

Gusty southwest winds will occur over the area today with most areas
seeing windy conditions by this afternoon. However, winds are
expected to remain below advisory levels. Temperatures will be
rather mild today and Tuesday over most areas, but some cooler air
will work into the area Tuesday afternoon across the northern areas.

.LONG TERM...Wednesday night through Sunday.

Models remain in pretty good agreement this morning, and there is
good run to run consistency as well, so confidence continues to
increase. For Wednesday night, fast and moist zonal flow continues
in the wake of the weak wave departing to the east. This will keep
small precip chances going in the Sierra and the southern Great
Basin. On Thursday, the next, and presumably last, storm in the
train will dig into the desert Southwest. The subtropical moisture
tap will be gone by this time, so this storm will have much less
moisture to work with than the storms of the preceding week. Slight
chance to low chance PoPs should spread over the entire CWA Thursday
and Thursday night, followed by drier northwest to north flow Friday
into Sunday. As noted yesterday, this drier flow is also somewhat
colder, and MOS temperatures continue to trend downward over the
weekend, so nudged the forecast in that direction again.
&&

.SPOTTER INFORMATION STATEMENT...Rainfall and snowfall totals are
encouraged through today. Reports of flooding or elevated stream
flows are also requested.

Update/Aviation...Adair
Short Term...Gorelow
Long Term...Morgan
