Area Forecast Discussion
National Weather Service Las Vegas NV
1004 AM PST Thu Dec 22 2016

.SYNOPSIS...A pair of weather systems will impact the region
heading into the weekend. The first is bringing precipitation to
southern parts of the area Today, then another more potent system
will bring gusty winds and additional precipitation on Saturday.
Cooler air will return to the region for the start of next week.
&&

.UPDATE...Another band of rain lifting northwest across southern
Nevada. This will likely begin to pivot and remain over the same
areas, leaving most areas around and south/east of I-15 in the soup
all day. An upper-level dry slot is working into Mohave county,
which will promote convective showers there today, with a few
rumbles of thunder not out of the question. Overall, another quarter
inch expected for the aforementioned areas, with locally higher
amounts, especially possible in southern Mohave county. Touched up
PoP and QPF grids through 6Z tonight.
&&

.PREV DISCUSSION...
Issued at 425 AM PST Thu Dec 22 2016

.SHORT TERM...through Tonight
Low pressure just offshore near the US/Mexico border continues to
stream moisture northward, bringing a band of showers through
central portions of the CWA this morning. Radar and satellite
imagery show a dry slot behind the band of showers across Clark and
central Mohave Counties. This will bring a break in shower activity
mid morning. High resolution models indicate a second band of
showers redeveloping and moving across San Bernardino, Clark, and
Mohave Counties this afternoon. Temperatures will remain near normal
for highs and warm lows due to the overcast conditions. Snow levels
remain high with the morning sounding indicating a freezing level of
9600 ft. As such snow is only expected at the very highest
elevations with minimal accumulation. The low will rapidly move
northeastward today and weaken, transitioning to an open wave
tonight, bringing the precipitation along with it. This will also
set the stage for another system moving in from the northwest on
Friday.

.LONG TERM...Friday through Wednesday
A strong, dynamic, moist and fairly cool low pressure system will
move to just about the California coast Friday afternoon. Snow will
spread into the Sierra by Friday afternoon with generally dry and
breezy conditions elsewhere. Portions of Inyo and Nye Counties may
see wind speeds increase enough during the afternoon to require a
wind advisory but will hold off on that for now. Other parts of the
forecast area will likely see the strongest winds Friday night but
it is possible that precipitation drag will keep winds from getting
too crazy strong. The trough will move inland across California and
Nevada Friday night and Saturday. The models are in pretty good
agreement that there will be a solid, roughly south-north oriented
band of precipitation ahead of the trough axis along a 100KT jet.
Confidence is pretty high that pretty much the entire forecast area
will get precipitation with this band as it progresses from west to
east through Saturday. There is some difference in timing with the
trough axis and how fast this band of precipitation will exit to the
east Saturday afternoon or evening. I decided to leave the Winter
Storm Watch as is for now due to timing concerns at this time. The
other issue regarding the Watch and possible upgrade to a Warning is
timing of cold air. The best moisture/precipitation may be before
the snow levels lower significantly so heavy snow may be limited to
the highest elevations. It looks like precipitation will be winding
down in the western CWA Saturday afternoon and by later Saturday
night, precipitation chances should be limited to mainly eastern
portions of Lincoln and Mohave Counties.

For Sunday through Wednesday the 00z models were actually in pretty
good agreement with the next low pressure system approaching the
coast Sunday diving south and remaining off shore as it head to off
the Baja Spur by Wednesday afternoon. This leaves our forecast area
dry through the period with temperatures warming to above normal
levels by Wednesday.

&&

.AVIATION...For McCarran...OVC cloud deck around 5 kft
will persist for much for the day today. There will be a break in
rainfall after about 16Z then a second round of light rain is
expected between 19Z and 02Z Friday. During this time there may be
periods of 5-6SM vsbys and cigs to 3 kft. Rain will let up and cigs
will increase after 02Z Friday

For the rest of southern Nevada...northwest Arizona...and southeast
California...Moisture still streaming into the area with best
chances of rain east/south of a DAG-DRA line through today,
lingering in northwest Arizona longer. CIGS will continue around 3-5
kft. Winds at most terminals will remain light, except down the
Colorado River Valley, where some north winds of 15-25kt will
linger, particularly at IFP. &&
