The episode as NWS REV wrote it up.
A more significant system moved through the region for the 6th through 8th|with heavy snowfall, strong winds, and falling snow levels. Snow accumulations of 6 to 10 inches below 7000 feet, with 2 to 3 feet possible at the highest mountain peaks were projected for this storm. Dangerous travel conditions were expected over the Sierra passes with this winter storm system. Strong winds also caused hazardous driving conditions for high-profile vehicles, turbulence and low-level wind shear for aviation interests, blown around unsecured objects, potentially blown down tree limbs, and power outages especially overnight on the 6th. Therefore, a Wind Advisory was issued for the Greater Reno- Carson City- Minden Area and Southern Lyon and Mineral counties. A Lake Wind Advisory was also issued for Pyramid Lake with the strong winds in the Sierra overlapping with the Winter Storm Warnings in effect.

.DISCUSSION...
Winter Storm Today through Friday:
* Heavy snow will pick up in the Sierra this afternoon and
continue through Friday morning. Snow accumulations of 6 to 10
inches below 7000 feet, with 2 to 3 feet possible at the
highest mountain peaks. If you are traveling this afternoon
through Friday morning, expect delays and be prepared for
dangerous travel conditions, particularly across Sierra passes.
Snow levels will drop down to the valley floors in western
Nevada by Friday, bringing a less than 5% probability of a trace
of snow in lower areas. Strong winds will cause hazardous
driving conditions for high-profile vehicles, turbulence and
low-level wind shear for aviation interests, blown around
unsecured objects, potentially blown down tree limbs, and power
outages especially Thursday night. As such, a Wind Advisory has
been issued for the Greater Reno- Carson City- Minden Area and
Southern Lyon and Mineral counties. A Lake Wind Advisory has
also been issued for Pyramid Lake. The strong winds in the
Sierra tonight will overlap with the Winter Storm Warnings that
will be in effect. For timing and details, please refer to these
products on weather.gov/reno.
Quieter Pattern this Weekend:
* After the storm departs the region, the weekend will bring drier
and calmer weather. Temperatures will stay on the colder side,
with overnight lows dipping into the teens in Nevada valleys and
colder single-digit temperatures in the Sierra. Winds will ease
up, providing a break from the stormy conditions, but the cold
will be noticeable.
Storms Return Next Week:
* Stormy weather could return as soon as Tuesday, bringing more snow
to the Sierra and possibly some to western Nevada. Snow levels
could vary from the valley floors to higher elevations depending
on how the storm develops. However, forecasts are still uncertain,
and confidence in the exact timing and details remains low. Stay
tuned for updates as we get closer to next week.

.AVIATION...
Strong Winds Thursday night into Friday morning:
* Strong south to southwest winds at FL100 (50 to 70 kts) will bring
turbulence and LLWS Thursday afternoon into Friday morning. Expect
gusts over 30 to 40 kts at terminals, with periods of gusts up to
50 kts. Rotors and wind shear near the Sierra will create
challenging flying conditions.
Heavy Sierra Snowfall/western Nevada rainfall:
* Snow starts late Thursday morning in the Sierra, with 1 to 2
inches expected at KTRK, 4 to 6 inches at KTVL, and 2 to 3 inches
at KMMH by Friday morning. Lower-elevation airports (KRNO, KCXP,
and KMEV) may see light snowfall with minimal accumulation. Expect
periods of IFR and LIFR in the Sierra due to snowfall and lowered
CIGS. Mountain obscurations and MVFR conditions will be prevalent
across western Nevada as rain spills over the Sierra.
Calm this weekend:
* VFR conditions return with lighter winds and cold mornings. Watch
for FZFG at KTRK and widespread frost during the overnight and
early morning hours.
