1231 PM PST Sat Jan 7 2023

A series of systems will impact the region through the middle part

and flooding impacts to the lower elevations. Regardless, major 
snowfall accumulations are likely for the Sierra with chances 
increasing for major snow impacts in western Nevada, particularly

* IMPACTS...Travel could be very difficult to impossible. The 
  hazardous conditions could impact the morning or evening 
  commute. Gusty winds could bring down tree branches.

What forecasters said that day

The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Reno, NV wrote its last area forecast discussion before this winter storm warning went out at Jan 5, 2:22 PM PST, 12 hours 15 minutes earlier.

Area forecast discussion, Jan 5, 2:22 PM PST, 12 hours 15 minutes before
Area Forecast Discussion
National Weather Service Reno NV
222 PM PST Thu Jan 5 2023

.SYNOPSIS...

Occasional rain/snow showers will continue throughout much of today
before tapering off Friday morning. Weak ridging aloft will provide a
brief lull in the active weather tomorrow before the next in a series
of winter storms arrives this weekend. A potent atmospheric river event
is expected to impact the region early next week, bringing heavy
mountain snow, gusty winds, and possibly low elevation flooding
concerns.

.SHORT TERM (THROUGH FRIDAY NIGHT)...

As of 2 PM, a few lingering snow showers are evident on radar
observations and local webcams moving northeastward over the Sierra
crest, mainly along/south the I-80 corridor. Some rain and light snow
flurries reached the surface in the Truckee Meadows area earlier this
morning, and again notably in the early afternoon, but much of the
precipitation is being shadowed out for far western Nevada valleys
under a predominantly south flow aloft. Occasional snow showers will
persist in the Sierra for the remainder of today and into early
tomorrow morning before all shower activity comes to an end (for
now...). Gusty ridgetop winds will gradually dissipate throughout the
afternoon and evening today, becoming periodically breezy for Friday.

A transient, shortwave ridge will build into the region, allowing for a
short-lived intermission in the active weather for Friday. Temperatures
will continue to run 5-10 degrees below average by early January
standards with highs reaching the upper-30s/mid-40s for western Nevada
valleys and 30's for Sierra communities. Overnight, sub-freezing lows
will continue Friday into Saturday, though increasing cloud cover ahead
of the approaching storm will modulate lows to be a bit warmer relative
to tonight's lows. For details on this weekends storm, please refer to
the long term discussion.

.LONG TERM...

WEEKEND STORM (SATURDAY-SUNDAY):

Bringing this weekend’s forecast into focus, it becomes apparent
that two distinct winter systems drive into the region bringing
another round of rain, snow, and wind. These elements once again
work together to bring the travel impacts that we have all come
accustomed so far. The first system will briefly scoop up
available sub-tropical moisture before sweeping across the Sierra
into western NV Saturday. A second, slightly stronger Pacific
system with better forcing and slightly cooler temperatures will
forage remaining Pacific moisture before quickly driving east into
the west coast. This system will bring another shot of moderate
to heavy mountain snow. The colder temperature with this second
wave of moisture will bring snow levels down to valley floors over
western Nevada overnight Saturday into Sunday morning.

* Model guidance still projects much lighter snowfall totals for
  the first system with a few inches of new snow staying mostly
  north of I-80. With the second wave, blended guidance favors a
  40% chance of snowfall totals of 8-12 inches around the Lake
  Tahoe basin with the same chances for something between 1-3
  inches of accumulated snow down to the valley floors overnight
  Saturday into Sunday morning. Another 2 feet plus of newly
  fallen snow will once again adorn the Sierra crest.

* Winds this weekend across the Sierra crest in excess of 80 mph
  will also contribute to aviation concerns across the area that
  will propagate east into far western NV. Northeast CA and
  northwest NV will also see breezier conditions with wind gusts
  topping 30-40 mph with passage of both fronts through the
  region.

* IMPACTS: With the one-two punch of Pacific storms this weekend,
  travel over Sierra passes will be slippery and slow. So extra
  caution is advised if there is a need to be in the mountains this
  weekend.

STRONG ATMOSPHERIC RIVER (MONDAY-WEDNESDAY):

* Confidence remains high for a strong atmospheric river (AR)
  impacting the West Coast Monday into Tuesday morning, allowing
  for a weak rain shadow to occur (strong spillover) into far
  western Nevada. Although ensemble model guidance continues to
  trend higher forecast precipitation values and snow amounts for
  the Sierra and western NV through the first half next week, a
  variety of warmer and wetter scenarios are still possible for
  this system as higher resolution model guidance begins to
  influence the nearer term forecast guidance.

* The impacts will still cover a range of possibilities from major
  winter travel impacts in over Sierra passes and heavy rainfall
  in western Nevada. With underlying soils and the mountain
  snowpack better primed for more efficient rapid run-off, the
  potential for flooding on rivers and creeks could become a very
  real concern. Keep close monitoring of area forecasts and plan
  on impending travel impacts Monday through Wednesday across the
  region. Consider alternative travel plans to avoid this storm
  and its potential impacts.

LOOKING BEYOND NEXT WEEK:

* The active storm pattern continues, with the wet pattern
  continuing into the middle, if not the end, of January.
  Significant amounts of rain and snow are still expected across
  the Sierra crest during this period. But ensemble simulations
  are percolating up chances for a drier, more stable period
  towards the later half of the month

-Amanda

&&

.AVIATION...

* Orographically enhanced snow showers will continue mostly in and
  around Sierra terminals through tonight. Some heavier bands of
  moderate snow showers will bring brief periods of IFR conditions
  in CIG/VIS to KSVE-KTRK-KTVL till 06Z, but taper off by 09Z as
  drier air moves into the region through Friday morning.

* A few light showers may overshoot into KCXP and KMEV and bring
  brief periods of MVFR conditions this evening. Lingering low level
  moisture will produce linger low stratus and continued terrain
  obscurations to Sierra terminals through Friday morning.

* Winds aloft staying remain elevated (FL100 sustained 25-30kts)
  with period of strong turbulence continuing over the area
  through 06Z. But wind shear will remain a concern through this
  evening especially in/out of KRNO. Overnight tonight into Friday
  FL100 winds will diminish below 20 kts through Friday.

* Winds aloft will once again push into the 40-50kt range at FL100
  on Saturday that increases turbulence concerns across the region.
  A stronger atmospheric river will impact the region Monday into
  Tuesday.
