Synopsis
A strong, fast-moving storm pushes into the region Sunday and
Sunday night, bringing gusty winds, valley rain and high
elevation snow. Snow levels will drop quickly late Sunday,
bringing widespread snow impacts to the region. Brisk and cooler
conditions will follow Monday with a generally quiet pattern
developing for the remainder of next week.

Short term
Forecast changes for today include increasing QPF snow amounts for
the high sierra above 7000 feet, as well as dropping snow levels
after 4pm Sunday as the colder air moves into the region.

Models continue to show a fast-moving, dynamic system moving
through the region Sunday and Sunday night. The instability and
dynamics with this storm are impressive, nearly 300j kg and lifted
indices around -2, we could even see some embedded thunderstorms
tomorrow as this storm moves in. The high-resolution models are
now suggesting 3-4 inches of QPF along the sierra crest. We have
not gone that heavy in the official forecast, but we have
increased the amounts to near 2.5" along the crest, with around
1-1.5" around the tahoe basin itself. Strong gusty winds can be
expected Sunday, especially along the sierra front where gusts up
to 45 mph may be expected. Lake wind advisory has been issued for
pyramid lake tomorrow, due to the potentially hazardous winds and
waves.

Snow levels will be around 7000 feet during the day on Sunday,
with snow mainly affecting the passes around tahoe. Very unstable
conditions in the thermal profiles should be able to bring down
snow levels, especially in the heaviest showers. Several inches
of snow accumulation are possible during the day, although mainly
slushy accumulations on the passes are expected before 4 pm. As
for the middle and lower elevations in the northern sierra,
western nevada and northeast california, rain will be expected for
the majority of the storm with little to no snow impacts until
later Sunday night after the frontal passage.

Around 4 pm, snow levels crash down to lake tahoe level and down
to valley floors in western nevada by 10pm Sunday night. Now this
is a precipitous drop in snow levels, an impressive 3000 feet
lower within 6 hours. With that snow level drop, there brings some
uncertainty in the forecast snow amounts for those elevations
between 7000' and 4000' elevation. There should be enough moisture
behind the front to get accumulating snow down to the lower
elevations, although less and less accumulations the further you
drop in elevation.

Our best estimates for snow totals will be around 4-8" around the
lake tahoe basin (6000-7000ft), with up to 1 to 2+ feet above
7000 feet. If snow levels fall quicker than anticipated, those
numbers could be doubled. Down lower, up to a few inches may be
possible above 5000 feet in northeast california and foothills in
western nevada, including around virginia city. There is even a
slight chance we could see an inch or less of accumulation late
Sunday night on the valley floors in western nevada, including
susanville, reno-sparks, and carson city-minden.

Snow amounts will be less in mono county as the storm system
loses much of it's punch as it moves south. Still, we should see
at least moderate snow and blowing snow along us-395 in mono
county Sunday night, including mammoth lakes, lee vining, and
bridgeport. Be heads up for gusty winds and blowing snow along
highway 395 creating low visibilities Sunday night into Monday
morning.

Slick road conditions will continue throughout the region into
Monday morning (martin luther king, jr day). Luckily for most
folks, this is a holiday, but for those of us who work on Monday
it could be a slick and icy commute. We could see some additional
snow accumulations east of lovelock and fallon Monday morning.

Brisk and cool conditions will continue through the day on Monday.

The storm system then pushes out of the region Monday afternoon
into Tuesday, with clearing skies and cooler temperatures. -hoon

Long term Wednesday through Saturday...

a high-pressure ridge, with axis just offshore of the west coast,
should bring tranquil weather to the east sierra west nevada region
Wednesday-Thursday. Expect north-to-northeast low-level flow, light
surface winds, and no precipitation. For Friday-Saturday, the
location and amplitude of the aforementioned ridge axis are still
low-confidence forecasts. The ridge could begin to break down, but
overall some form of ridging looks likely (through at least
Saturday). Thus, the Friday-Saturday forecast for the east
sierra west nevada region calls for continued light winds and no
precipitation. Jcm

Aviation
Light winds with increased cloud cover is taking place this
afternoon ahead of yet another storm system set to impact the region
Sunday into early Monday morning. Ridge winds have already begun to
pick up in speed and will continue to do so during the overnight
hours.

As the low pressure system makes its way Sunday, south to southwest
winds for all area terminals will be gusty with speeds of up to 35
kts with even stronger winds aloft. Expect mechanical turbulence as
well as local llws, especially as the system's associated cold front
moves through the region Sunday night. Once the front makes its way,
lighter northwest winds will result.

As for precipitation, snow rain showers are likely to begin around
15z Sunday morning from the tahoe basin northward where CIGS & vis
are expected to lower to MVFR ifr criteria. Conditions deteriorate
even further and spread farther south and east during the evening
hours as snow levels begin to descend and snowfall intensity
increases. Ktrk, ktvl, & kmmh will see the most impacts with 4 to 8
inches of accumulation forecast by Monday morning. The western
nevada terminals (krno kcxp knfl) will experience light rain showers
at first, changing over to light snow by 03-04z Monday with the
passage of the front. Little accumulation is anticipated for these
areas.

Besides from a brisk, northwest wind during the day on Monday,VFR
conditions will be the case through the rest of next week as a ridge
builds off the u.S. West coast leading to much better flying
conditions. -laguardia
