Area Forecast Discussion
National Weather Service Las Vegas NV
128 PM PST Thu Feb 13 2025

.SYNOPSIS...Valley rain and mountain snow will continue across
large swaths of the forecast area into tonight with a cold front
passage. Gusty southwest winds ahead of the front can also be
expected. Additional showers and thunderstorms may occur
tomorrow. Warm and dry conditions are forecast over the weekend.
&&

.SHORT TERM...Through Friday.

An atmospheric river continues to bring widespread precipitation to
southern Nevada, southeastern California, and northwestern Arizona
through the evening. Snow levels rise throughout the day today due
to warm air advection and should be between 5500 to 6500 feet
tonight. The forecast appears to be on track for the most part,
aside from some overperformance of precipitation amounts in Owens
Valley and underperformance of snowfall in the Spring Mountains
earlier today. However, a heavier band of precipitation should move
across the area with a cold front passage later this afternoon and
evening. The heaviest snowfall over high terrain outside of the
Sierra should occur with the frontal passage due to increased
moisture and favorable upslope flow. Snowfall rates of several
inches per hour can occur above 9000 feet on Charleston Peak.  Most
likely rainfall totals in Las Vegas after this band passes tonight
should be between .25 and .4 inch according to the HREF. The highest
observed precipitation totals at this point have been in the Owens
Valley with totals between .5 and 1.5 inch and localized amounts up
to 2 inches. Rainfall should slow down there one the front passes
and spillover moisture from the Sierra tapers off. The Flood Watch
for Owens Valley remains in effect through this evening. The Winter
Weather Advisory for Lincoln County ends at 10 PM tonight as
snowfall should largely end after the frontal passage, but the
Winter Storm Warnings for the Sierra, White Mountains, Spring
Mountains, and Sheep Range remain until 4 PM tomorrow to cover
additional snowfall and gusty winds.

The strongest winds seen so far have been in Esmeralda, Inyo, and
Nye counties with southerly gusts peaked around 45 mph. These winds
should decrease tonight and the Wind Advisory for these areas along
with Lincoln County expire at 10 PM PST tonight. Gusty southwesterly
winds are still forecast for parts of San Bernardino, Clark, and
Mohave counties through tonight ahead of the cold front, but have
underperformed so far. Wind gusts between 40 and 50 mph may hang on
in western San Bernardino County through most of Friday and Wind
Advisories have been issued to reflect these trends.

The main stream of moisture advection from the Pacific Ocean will be
pushed east tonight as the upper level trough starts to exit the
area. However, a combination of residual moisture and surface
heating may lead to isolated shower and thunderstorm development in
southern Nevada and northwestern Arizona on Friday. Cool
temperatures aloft may allow for small hail with some cells. Any
rain or snow accumulations should be light.

.LONG TERM...Saturday through Wednesday.

Dry northwesterly flow will be in place across the southern Great
Basin and Mojave Desert on Saturday as a ridge of high pressure
builds into the area. The dry weather will persist on Sunday with
temperatures at or slightly below their seasonal normals which is in
the low 60s in the Las Vegas Valley.

The next system approaches from the northwest on Monday, and should
generally be dry but a showers couldn't be ruled out across then
northern portions of Lincoln County. However, behind the system will
be some gusty north winds, particularly down the Colorado River
Valley with probabilities of reach 40+ mph in the 35-45% range.
We'll need to monitor to see if there is the need for a Lake Wind
and Wind advisory. Weak systems moving down the front side of a West
Coast ridge will generally keep temperatures from moving very much
through mid week.
&&

.AVIATION...For Harry Reid...For the 18Z Forecast Package... Periods
of rain will continue through the afternoon and evening.  The latest
HRRR guidance is showing a band of heavier precipitation moving
across the valley between 01Z and 06Z.  CIGs are expected to remain
in the 3kft to 4kft AGL range through this afternoon but may fall to
1.5kft to 2kft AGL as the heavier precipitation band moves through.
Visibilities may fall to around 2SM with that band as well.   Due to
the precipitation in the area today, winds should remain light
through the afternoon.  An increase in south to southwest winds is
expected this evening and overnight, but the confidence on the
timing of this increase is low, and it could occur anytime between
00Z and 06Z.  Conditions will gradually improve tomorrow, although a
few isolated convective showers will be possible during the
afternoon and evening as the trough axis passes across the area.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Very poor conditions are
expected throughout today, as MVFR to IFR ceilings and visibilities
continue to spread over the region from southwest to northeast.
Widespread rain and mountain snow can be expected, along with
terrain obscuration. CIGs falling to around 2kft to 3kft AGL, along
with visibilities lowering to less than 3SM are possible at times
through this evening. Increasing south-to-southwest winds will be
seen across much of the region later this afternoon and evening,
although confidence in the timing of the increases is low.  Once the
winds do increase, valley locations will see 15 to 25 knots gusts,
while the higher elevations could gust to 35 to 45 kts. Conditions
will improve from northwest to southeast late this evening and
overnight.  However, a few scattered showers and possibly a
thunderstorm or two are possible on Friday, primarily over the
higher terrain north and east of the Las Vegas area.

any significant weather or impacts according to standard operating
procedures.
