Synopsis
Low clouds have mostly broken for valley locations this afternoon.

Higher clouds should keep low clouds from reforming overnight.

Two weak systems will move through the region, one today and
another Tuesday night into Wednesday. This afternoon and evening,
a few snow flurries will be possible around the region, but
accumulations remain unlikely. Mixing and winds increase a little
by mid week as the next system moving through the region. The
pattern remains active with additional storms possible the next
weekend into the start of the following week.

Short term
There were no major changes made to the existing forecast. A weak
wave is presently moving through the region early this afternoon
bringing a few flurries along the sierra front and in the sierra.

There has been little to no accumulation with this wave. Still,
highest elevations could see an inch or so through this evening.

This wave will continue to weaken as it pushes through.

Fortunately, low clouds did break late this morning allowing some
rays of sunshine before higher clouds filled in. These high
clouds should keep low clouds at bay overnight. However, strong
inversions remain in place and deep scouring of low level moisture
and pollutants has not occurred. A likely scenario for western
nevada valleys overnight will be that some ragged low clouds form
along area ranges, but not thicken or completely fill in the
valleys overnight. If some locations do end up clearing out of
higher clouds, it would be possible for fog stratus to redevelop.

Another wave will begin to push through Tuesday night. Some light
snow and mixed precipitation will be possible mainly towards the
oregon border and in eastern nevada. Winds will increase with
pressure gradients supporting gusts around 35 mph along and behind
the boundary. The rest of the region will be treated to a dry,
back-door front. Model guidance favors improving mixing along the
sierra front that could scour our persistent low-level moisture
with gusts generally around 20 mph for Wednesday. Boyd

Long term Friday through Monday...

a little more active pattern is expected by the weekend as a couple
of fast moving system are poised to move through the region. The
first system of Friday won't be a big precipitation producer but
mainly will provide some gusty winds particularly across the sierra
and along the highway 395 corridor. As it stands, gusts look to be
mainly in the 40-50 mph range. Enough to cause some travel issues
for high profile vehicles, aviation turbulence, and hazardous
boating on area lakes. Precipitation with this system looks to
arrive in the late afternoon into early evening timeframe. Much of
this will be snow as snow levels still look to be near 5,000-5,500
feet but only looking to be a couple of inches across sierra passes
which still may result in longer travel times.

The next system looks to move through on the Sunday-Sunday evening
time frame and has the potential to be a little stronger and wetter
system. However, confidence is lower with this system as it does
show some tendency to be a splitting system. That is, much of the
moisture can dig too far south so the sierra misses the bulk of the
incoming moisture. Latest ec and ensembles are not showing a
dramatic split so have increased chances for precipitation. Those
with travel plans on Sunday should monitor the forecast through the
week as this system may provide a better potential for producing
significant travel problems across the sierra. Fuentes

Aviation
Light snow showers are currently moving SW to ne, from ktrk to krno.

These showers should taper off through the evening hours, but
periods of lowered ceilings and visibilities are possible. Other
than that, winds will remain light through tomorrow andVFR
conditions will prevail at krno kcxp ktvl kmmh.

Ktrk will be on the far western edge of the cloud deck this evening.

If skies clear sufficiently, fog will be possible. Either way,
expect a low cloud deck there overnight.

A system will move through Tuesday night, but impacts will be
limited, with light snow chances possible at ktrk ktvl. Another
system is expected Friday, with impacts due to gusty winds, mountain
obscurations, and lowered ceilings and visibilities. Cl
