Area Forecast Discussion
National Weather Service Reno NV
252 AM PST Sat Dec 11 2021

.SYNOPSIS...

Clear, calm, and chilly conditions will continue for today, with
winds beginning to increase tonight into Sunday. A major winter
storm with strong winds, significant snow in the Sierra and a mix
of rain and snow for western Nevada arrives Sunday through
Tuesday. Lengthy travel delays in the Sierra are nearly certain.
Another, albeit weaker, winter storm follows right behind this
one.

&&

.DISCUSSION...

If you live in the Sierra, today is the final day to prepare for a
multi-day winter storm that will likely be remembered for years to
come. Bottom line up front: Travel in the Sierra is expected to be
extremely slow if not impossible at times due to heavy snow
beginning Sunday for those areas near and north of US-50, spreading
south with all Sierra travel affected by Monday. Peak intensity snow
rates could reach 1-3"/hour from Sunday night through Tuesday. While
some rain and snow will reach western Nevada Sunday, the bulk of the
precipitation is anticipated Monday into Tuesday.

While the storm will begin to wind down by Tuesday evening, digging
out after the storm may keep travel impacted into Wednesday. Then,
there is another winter storm following right on its heels midday
Wednesday into Thursday night. Be sure you are ready for the
storm by winterizing your home and car and being sure you have
proper supplies for several days, if not the week ahead. If you
need to cross the Sierra, your best bet would be get it done
today, or wait until the end of the week. Check in with our
partners at NDOT, CalTrans, CHP, and NHP for any road condition
information.

Here are the highlights:

* SNOW:

Snow totals will be measured in feet in the Sierra and could easily
surpass a foot for higher elevations (6000+ feet) in western Nevada,
with several inches down to valley floors.

Probabilities for various totals:

Sierra Crest: 4+ feet - 95%, 6+ feet - 70%
Tahoe Basin and Northeast CA west of US-395: 2-3+ feet - 75-95%
Communities along US-395 in the Ern Sierra: 2+ feet - 70%

With this amount of snow, avalanches certainly become a concern. We
will defer to our friends at the Sierra Avalanche Center and the
Eastern Sierra Avalanche Center for the latest guidance on
backcountry avalanche thinking.

As far as snow "down here", the variations in snow levels bring
quite the range of possibilities for the lower valleys, with inch or
two (70-90% chance per NBM) upward to nearly a foot of snow (10-25%
chance, elevation dependent) at this point. Places like Virginia
City, however, are going to be predominately snow with 1-2 feet
expected. Anticipate large ranges in snow totals between elevations
in the 5000-5500' range as compared to the 4500-5000' range. The
slightly higher elevations could see 6-12" of snow, whereas the
valley floor may only see 2-4".

* SNOW LEVELS:

The biggest question mark with snow levels are for areas below 5500-
6000'. Anything above 6000' should stay as snow for the entire
event. While valleys could go back and forth between rain and snow
through the event, there is high confidence in a full transition
to snow with the cold front Monday night into Tuesday morning. The
latest blended guidance is showing snow levels falling faster,
which could mean we end up with higher snow totals for the
valleys. Have issued Winter Storm Watches to account for this for
all areas not already under a Winter Storm Warning, outside of
the West Central Nevada Basin and Range. The only reason this zone
is not in a watch is due to the fact it contains the overall
lowest elevations in the region and also will see generally less
liquid totals, meaning lesser snow [read: not zero!] totals than
other areas. For valley locations: be prepared for periods of
slower travel Monday, and in particular the commutes on Tuesday.

* THUNDERSNOW?:

Yup. This one is definitely on the table Monday night into Tuesday
morning with unstable air from the low moving inland. If this
does occur, localized heavier snowfall rates and/or lowering of
snow levels is possible.

* LIQUID TOTALS:

Very little change to overall anticipated liquid totals, which
remain impressive due to a slow moving atmospheric river.

The colder nature of this storm means little to no chance for
river flooding, and the ensemble RFC guidance reflects this.
However, urban ponding of water from poor drainage is certainly
possible in the lower valleys due to heavy rain Monday before the
transition to snow.

* WIND:

700-mb winds remain impressive, with 45-55 kts in forecast
simulations. This is plenty of wind energy aloft, but with heavier
precipitation rates, the stronger winds are more likely to be
damped out. We'll continue to watch wind prone locations along the
Sierra Front Sunday and Sunday night, with the wind risk shifting
south of US-50 for Monday and Monday night. The areas that stand
out currently are wind prone locations along the US-395 corridor
in the Eastern Sierra and US-95 near Walker Lake/Hawthorne before
the precipitation arrives. There is an 80% chance for seeing max
wind gusts exceed 60 mph in these areas during that time frame.
For other locations, this is the type of situation where seemingly
random strong wind gusts may periodically surface if
precipitation rates slow. Sierra ridges are expected to see winds
gusting over 100 mph at times leading to near white-out
conditions along with the snow.

* BEYOND THIS STORM:

The pattern remains active with another winter storm moving in
midday Wednesday and lasting possibly through Thursday evening.
This storm has been trending stronger, but not as strong as the
initial system early in the week. Still, an additional 1-2 feet of
snow is possible in the Sierra, and with a cold air mass already
in place, up to several inches for western Nevada if it holds
together. General troughiness continues thereafter, so while we
are not seeing signs of another major storm, additional weaker
systems are still on the table. Temperatures will remain on the
chilly side as well. CPC 8-14 day outlook is continuing to show
better odds for below normal temps and above normal chances for
precipitation in the Dec 18-24 window.

.AVIATION...

This morning into Today:

* Patchy fog will be possible in Sierra Valleys early this
  morning. Besides this, VFR conditions will prevail today with an
  increase in winds and LLWS possible for northeast CA/Sierra/far
  western NV terminals.

A major winter storm will impact the region beginning early Sunday
and lasting through Tuesday. Significant impacts to aviation are
expected.

Winds/LLWS:

* Gusty southerly winds, mountain wave turbulence, and LLWS increase
  this afternoon into Sunday as the leading edge of the storm moves
  into California. Surface gusts should remain below 40 kts for most
  terminals, with a 20-30% chance of gusts exceeding 50 kts at TRK-
  TVL-CXP-RNO. Enhanced LLWS is likely at KRNO due to the southerly
  winds.

* The strongest winds will move through the region Monday into
  Monday night. At this time, there is a 50-60% chance of surface
  gusts exceeding 50 kts for RNO-CXP-MEV-MMH with southerly winds
  and LLWS anticipated. For the Sierra terminals of TRK and TVL,
  there will be a high chance of LLWS and a 60-70% chance of wind
  gusts exceeding 50 kts. But these wind gusts may be hampered by
  heavy snowfall.

Snowfall:

* TRK-TVL: snow will begin early Sunday morning, with heavy snow a
  sure bet Monday into Tuesday. Accumulations will likely exceed 2
  feet, with IFR/LIFR conditions expected from Sunday through
  Tuesday.

* RNO-CXP-MEV: the highest probability for rain and snowfall will be
  Monday afternoon into Tuesday morning. Snow should begin
  accumulating Monday night at these terminals as snow levels drop
  to valley floors. Accumulations will likely exceed 2 inches, with
  CXP-MEV having an 80-90% chance of exceeding 4 inches. RNO has a
  60% chance of exceeding 4 inches.

* MMH: Snow begins Sunday night, with heavy snow and long duration
  IFR/LIFR conditions expected Monday into Tuesday. Accumulations
  will likely exceed 1 foot, with a 50% chance of exceeding 18
  inches.

Another storm is possible midday Wednesday lasting possibly into
Thursday evening. The Sierra will likely see heavy snow and
western NV may see several inches of snowfall. Something to keep
an eye on.
