Area Forecast Discussion
National Weather Service Las Vegas NV
700 PM PST Sun Jan 15 2023

.SYNOPSIS...The next system will move into the area tonight and
Monday bringing another round of heavy mountain snow and wide
spread valley rain to the area. Dry, cooler weather is expected
for the remainder of the week, however a system dropping in from
the north on Thursday could result in light showers across parts
of the area.

&&

.UPDATE...Starting to see some light showers develop across the
western Mojave Desert ahead of next shortwave coming into
California. HRRR indicates showers will continue to develop and
spread east-northeast into southern Nevada and northwest Arizona
late this evening through Monday morning. HRRR suggests lines of
showers and isolated thunderstorms developing under more unstable
air mass tomorrow afternoon into the evening. Most of the QPF is
expected to fall in the next 24-30 hours with lighter wrap around
precipitation lingering in parts of southern Nevada and northwest
Arizona into Tuesday. Expecting some stronger winds to develop
within the Mojave Desert tomorrow. Winds back off some tomorrow
night only to increase and shift from the west-northwest with the
cold frontal passage. Not committed to any wind headlines yet but
will take a close look as I work through the upcoming forecast
for tonight. See no adjustments needed at this time.
&&

.PREV DISCUSSION...159 PM PST Sun Jan 15 2023
.DISCUSSION...Tonight through Tuesday.

The next storm to bring impacts to our area begins tonight with
heavy snow getting underway after 10 pm this evening in the
Sierra and after 4 am Monday elsewhere. Multiple areas are under
Winter Storm Warnings for expected heavy snowfall overnight into
Monday. Upgraded the Winter Weather Advisory in effect for Mohave
County to a Winter Storm Warning primarily based on precipitation
amounts forecast for the Northwest Plateau. Lesser amounts are
expected across central Mohave County including the Hualapai
Mountains where 3-6 inches are expected on Hualapai Road with
higher amounts at Hualapai peak. This system is expected to bring
widespread valley rain to the area as well - generally ranging
from a few hundreths up to 1.50 inches. For the Las Vegas area,
current forecast amounts range from 0.10-0.50 inches with locally
higher amounts on the far west side.

The other concern with this system is gusty wind conditions across
the deserts. Borderline advisory level winds are forecast for the
Western Mojave Desert and the Morongo Basin area Monday afternoon.
No headlines yet but they could be needed at some point.

Showers linger across parts of the area Monday night and even into
Tuesday before dry conditions set in on Wednesday and continue
through the weekend. High pressure building off the coast will
essentially cutoff any AR moisture from reaching the coastal
states for an extended period of time. The position of the high
however will open the door for colder systems dropping into the
area from the north which is the case for late Wednesday night
and Thursday. Precipitation chances with that system are forecast
to increase but amounts will generally be light. There is also
some uncertainty tied that this system regarding whether it will
be an drier, inside slider as depicted by the EC ensemble
solutions or the slightly wetter GEFS/GEPS solutions.

Beyond Thursday, dry weather is forecast Friday through the
weekend. Temperatures are expected to bottom out Thursday and
Friday around 10 degrees below normal before rebounding slightly
over the weekend but still remaining well below normal.

&&

.AVIATION...For Harry Reid...South to southwest winds gusting to 25
kts at times will continue through the late afternoon before
decreasing overnight.  VFR conditions are expected through this
afternoon, but CIGs will lower once again overnight, falling to 3 to
5 kft by 2 AM as scattered showers move into the terminal area.  The
threat of showers will continue through Monday afternoon before
ending in the evening.  While not included in the latest TAF
package, CIGs may fall below 3 kft tomorrow morning and afternoon in
heavier precipitation.  An isolated thundershower is also possible
tomorrow afternoon, most likely between 10 AM and 4 PM.

For the rest of southern Nevada, northwest Arizona and southeast
California...South to southwest winds are expected at regional TAF
sites into this evening as the area remains between two storm
systems.  VFR conditions are expected through the afternoon, but
CIGs will lower overnight as the next system approaches.  Most sites
will see CIGs fall to 3 to 5 kft by tomorrow morning as rain and
snow showers spread across the area, although CIGs lower than 3 kft
will be possible in areas of heavier precipitation.  A few isolated
thundershowers are also possible Monday afternoon, mainly across
southern Nevada and northwest Arizona.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
