.SYNOPSIS...
* Wet and windy weather continues through Friday, with valley
rain, mountain snow, and a burst of strong winds early Friday
morning for the Sierra Front and the Eastern Sierra.
* Another storm arrives Sunday, bringing more Sierra snow, valley
rain, and gusty winds.
* Dry and milder weather returns next week with occasional light
showers and valley inversions possible.
&&
.DISCUSSION...
Current Storm - through Friday:
* Winds: Strong gusts up to 60+ mph are likely early Friday for
the Reno-Carson-Minden area and Mono County. Surrounding areas
will see gusts of 45+ mph. Sierra ridges may see gusts up to
140 mph, creating hazardous conditions for travel and
backcountry recreation. High Wind Warnings and Wind Advisories
are in effect.
* Precipitation: Expect Sierra snow above 6000 ft, with totals
exceeding 12 inches along the highest passes. Valley rain will
result in wet roads, with slick conditions possible in colder
areas. Winter Weather Advisories remain in effect for northeast
California, the Greater Lake Tahoe Area, and Mono County.
* Travel impacts: Be prepared for difficult travel due to snow
and high winds. Check road conditions with CalTrans and NDOT,
and flight schedules before traveling.
Break in Weather - Saturday:
* A brief dry period is expected Saturday, with increasing winds
along ridges in the evening.
Next Storm - Late Saturday Night-Sunday:
* Winds: Another round of strong winds with gusts up to 50+ mph
in valleys and 100+ mph on Sierra ridges.
* Precipitation: Light to moderate snow accumulations, with 2-6
inches possible at higher passes such as Donner Summit and
Carson Pass. Snow levels will start near 8000 feet Saturday
night before dropping to 5500-6000 feet by Sunday evening.
* Travel Impacts: Strong winds and snow may create additional
travel challenges.
Next Week:
* Drier and milder conditions return, but valley inversions and
light showers are possible. Stay updated on conditions and
travel safely!

.AVIATION...
* Strong W/NW flow aloft will persist through the weekend with waves
to pass through late tonight/Friday and again Sunday. Showers will
continue to favor the Sierra with brief periods of spillover.
Winds will also continue to be strong with each system with
rotors, moderate to severe turbulence and LLWS.
* Snow levels will remain high enough to precluded snow
accumulation for area terminals. Even at KMMH, where it will
snow at times, precipitation intensity will be very light as
storms focus north of that area. Periods of MVFR and terrain
obscurement(brief IFR conditions) for KTRK-KTVL. Brief MVFR at
KMMH with VFR lower elevation sites in brief rain showers.
* FL100 winds will continue to average 50+ kts with periods of
elevated winds to 70 kts associated with each wave. Some of latest
guidance indicates FL100 winds peaking around 80 kts at 12Z Friday
with downslope signature apparent along the lee of the Sierra
overnight. Given the W/NW trajectory of winds, would not be
surprised to see surface gusts 65+ kt for a 2-4 hour window from
KMEV-KMMH (30% chance) overnight.
* Quiet stretch of weather expected Mon-Thu (New Year`s travel
plans) with VFR outside of Sierra valley fog and much lighter
winds.

.AVALANCHE...
Two winter storms will impact the Sierra, the first through Friday
morning, and the second late Saturday night into Sunday. The
first storm will bring light to moderate snow accumulations to the
Sierra and strong winds, especially late tonight into Friday
morning. The second storm looks to bring much lighter snowfall
accumulations with the main impact being strong, gusty winds.
Storm 1 (Through Friday):
* Timing: Snow levels rising to 8000 feet today; precipitation
peaks tonight into Friday morning.
* Snow Levels: Initial snow levels near 5500 feet, rising to
8000 feet by Friday.
* Winds: Sustained ridge winds above 70 mph with gusts up to 140
mph, contributing to wind shear at ridgetop level.
* Precipitation: Up to 2 inches of liquid equivalent along the Sierra
crest in the Tahoe Basin and 0.90-1.50 inches of liquid
equivalent along the Sierra crest in the Eastern Sierra, with
snowfall rates exceeding 1 inch per hour between 9 PM tonight
and 6 AM PST Friday.
* Probabilities: 50-80% chance of SWE exceeding 1 inch in 24 hours
above 7000 feet increasing from south to north along the
Sierralimited solar intensity due to dense cloud cover.
Storm 2 (Sunday):
* Timing: Precipitation begins late Saturday, peaks Sunday, and
transitions to showers Sunday night.
* Snow Levels: Falling from 8000 feet Saturday night to
5500-6000 feet by Sunday evening.
* Winds: Sustained ridge winds continue above 65 mph, with gusts
potentially exceeding 100 mph.
* Precipitation: 0.75 inches of liquid equivalent along the Sierra
crest west of Lake Tahoe and up 0.10-0.50 inches south into
the Eastern Sierra, with snowfall rates exceeding 0.5 inches
per hour at times.
* Probabilities: 15-40% chance of SWE exceeding 1 inch in 24 hours
above 7000 feetlimited solar intensity due to dense cloud
cover.
