Synopsis
A ridge of high pressure will keep mild temperatures and light
winds over the region through Tuesday, with cloud cover increasing
on Tuesday as this ridge gives way to an approaching storm system.

The best chance for valley rain and mountain snow will occur Tuesday
night through Wednesday, with unsettled and showery conditions
possible into next weekend.

Short term
Only a few small upward adjustments to precip chances and amounts
were made for the Tuesday night-Wednesday night periods as
confidence is reasonably high for much of the region to receive a
light to moderate precipitation event with an approaching storm
system.

Before this storm arrives, another couple of spring-like days are
expected with highs in the 60s for lower elevations and 50s for
sierra valleys. While for today we're expecting little or no cloud
cover and light winds, Tuesday will feature widespread mid-high
level cloud cover and some increase in east to southeast winds,
especially across northwest and west-central nv.

As the low approaches Tuesday night, forcing will increase with
deeper southeast flow spreading more moisture across the sierra
and into parts of western nv, with the better precip chances
arriving after midnight and continuing into much of Wednesday.

By Wednesday night, most of the precip shifts to areas south of
us-50 with wrap-around moisture bands as the main low slides
toward southern ca. Daytime temperatures on Wednesday will be
about 10-15 degrees cooler than Tuesday, with brisk east winds
prevailing mainly east of the us-395 corridor.

There have been subtle differences in which areas will receive
more precip, but at this time the higher totals favor the sierra
and eastern ca-western nv generally south and west of a
susanville-fallon line. In these areas, liquid totals of 0.25-0.50"
(and up to 0.75" near the sierra crest) are possible, with areas
to the east receiving between 0.10-0.25". As always, embedded
bands of heavier rain could bring locally higher totals.

This system is moderately cold with 700 mb temperatures generally
between -5 and -7 c during the bulk of this event. Snow levels
starting above 7000 feet Tuesday evening are expected to fall to
6000-6500 feet by early Wednesday morning and hover around those
levels during the day, then drop to near 5500 feet by Wednesday
night. Total snow accumulations could reach 6 to 12 inches above
7000 feet, then taper down to a couple of slushy inches possible
at lake level around tahoe, between 6000-6500 feet in mono county,
and in the virginia city highlands. Road temperatures are likely
to be on the warm side due to the recent mild days so only the
higher segments of the main sierra and carson range passes are
likely to be adversely impacted by accumulating snow slush, mainly
during the overnight hours. Mjd

Long term Thursday through Monday...

main change to the long term was reducing precipitation chances
beyond Saturday morning. The main chances for precipitation in the
long term will be Thursday, then Friday night into Saturday
morning, and possibly Monday (low confidence). Temperatures will
remain near or slightly below average late this week into early
next week.

Thursday will feature leftover rain and snow showers, with some
higher elevation (above ~6000 feet) snow-covered road conditions
possible through mid-morning. A break is expected Thursday night
into Friday ahead of the next fast-moving wave.

A few light showers are possible Friday for the sierra and
northeast ca; however, heavier precipitation and impacts from
snow currently look limited to Friday night into Saturday morning
when ec and GFS simulations bring an upper disturbance and
associated cold front through the region. Precipitation amounts
are still fairly uncertain as some simulations (including 00z gfs)
bring the heaviest numbers to far northern ca nv with a farther
north disturbance. Still, many simulations bring the low in
farther south, setting up areas as low as 4500-5000 feet with the
potential for a very light snowfall and slick conditions by
Saturday morning.

Another general break is expected Saturday night (possibly by
Saturday afternoon depending on your model choice) and Sunday with a
progressive upper ridge. Monday, the GFS brings another upper low
into northeast ca and western nv; however, the last couple ec runs
keep the upper ridge intact through Monday. GFS and ec ensembles
have a fair amount of spread over northern california and western
nevada Monday, which indicates the possibility of either
solution. Therefore, we can't give you any more than a broad-brush
slight chance to chance of precipitation for now. -snyder

Aviation
Vfr conditions with light terminal low level winds will persist
through much of Tuesday. Due to periods of high clouds, there is
only a modest (30%) chance for patchy fog at ktrk this morning and
Tuesday morning.

Tuesday night into Wednesday morning, an approaching upper level
trough will bring lowering ceilings, terrain obscuration, and rain
and higher elevation snow. Terminals possibly affected by light snow
include ktvl and kmmh. Winds aloft are expected to be south to
southeast later Tuesday into Wednesday. This is not favorable for
significant mountain wave turbulence east of the sierra crest.
