Area Forecast Discussion
National Weather Service Reno NV
255 AM PST Fri Feb 16 2018

.SYNOPSIS...

Temperatures will warm the next couple days with dry conditions
expected through Saturday. Another strong cold front will move
through the region Sunday into Sunday night bringing snow showers
and much colder temperatures for the start of next week. The
temperatures early next week are likely to be the coldest of the
season.

&&

.SHORT TERM...

Temperatures will continue to increase today and Saturday as
building high pressure off the coast allows warmer air to move back
into the region from the southwest. Dry northerly flow aloft will
keep skies clear and winds generally calm through Saturday morning.

Winds will begin to increase late Saturday afternoon, mainly in the
upper elevations and near the Oregon border, as the next cold front
begins to approach the region. Late Saturday night through Sunday
winds will be quite breezy with ridge winds gusting to around 90 mph
and gusts in the valleys in the 30-40 mph range.

This is another slider system, with a stronger cold front associated
with it then the last few systems. The overland trajectory of this
system will again keep total QPF low with very little available
moisture.

The front is expected to move through the region during the day on
Sunday with light to moderate travel impacts from snow probable.
Very cold temperatures behind the front will produce good
instability through the dendritic growth zone likely producing a
short period of moderate to heavy snowfall along and behind the
front Sunday. Highest snowfall accumulations will likely be in the
1-3 inch range with lower valleys in western Nevada most likely
in the 0-1" range. It is a distinct possibility that the snowfall
through the Reno/Carson City area could produce 1/2-1" of snow
late Sunday night with impacts to travel potentially lasting into
early Monday morning.

.LONG TERM...President`s Day through Thursday...

Cold trough settles into the Great Basin on Monday, bringing much
colder temperatures to the region and brisk winds gusting up to
20-30 mph. With the cold temperatures and potential for light snow
Sunday night into Monday morning, it`s possible that the Monday
morning commute could be slick, icy, and slow-going. Good thing
that it`s a holiday for many people, so the traffic will be less
Monday morning.

These temperatures on Monday and Tuesday will be the coldest days
we`ve seen so far this winter season along with frigid wind
chills dropping into the teens and single digits, especially in
the early morning hours. High temperatures will only be in the
30s across western Nevada with 20s in the Sierra valleys.
Scattered snow showers will continue through the day on Monday
underneath the cold pool aloft. It`s also pretty likely that we
will see lake effect snow banding downwind of Tahoe and Pyramid
Lakes, especially with the cold air and recent warm temperatures
keeping the lake waters relatively warm for this time of year.
This combined with a unidirectional northwest flow should get the
lake effect machine going. We`ll need to monitor this closely over
the next few days as this has the potential of being one of the
more favorable lake effect days we`ve seen in a while.

East flow will keep temperatures below normal Tuesday and
Wednesday, with only limited warming on Wednesday due to weak
ridging. The Pacific ridge remains out near 150W next week, which
will allow for more shortwaves to drop through the Pacific
Northwest and into our area late next week bringing more
reinforcing shots of cold air and chances for snow late next week
and even into next weekend. Hoon

.AVIATION...

VFR with light winds through 18Z Saturday. Some east winds near
KCXP again this afternoon. Winds will increase Saturday night
ahead of the next storm with peak gusts 35-40 kts at terminals
after 06Z Sun into Sunday afternoon. Some LLWS with mtn wave
turbulence is likely, especially from 06-18Z Sunday.

SHSN will progress south during the day Sunday with light
accumulations possible. X/Hoon
