.KEY MESSAGES...

* A lull in the precipitation is expected this morning before
  another weather system moves into the region later today and
  tonight, bringing additional rain and snow chances.

* Colder air will bring snow levels to near or below 4000 feet
  across much of the region, resulting in increased travel impacts
  to mountain travel routes.

.DISCUSSION...through early next week.

The first wave of our storm series has largely cleared the area
with drier conditions in its wake. Winds remain quite gusty and
will remain elevated for most of the region today ahead of the
next weather impulse slated to move in later today and tonight.
Wind advisories have been extended into Wednesday morning for much
of the region, and into Wednesday evening across the San
Bernardino Desert zones where westerly winds will linger longer.

Our next weather system is currently dropping into Northern
California, with considerable convective shower activity noted on
satellite coming in off the Pacific Coast, indicative of very cold
air aloft moving over the warmer Pacific waters. This colder air
mass will sag into our region later today and tonight, with
renewed snowfall along the Sierra early this morning, and rain
and snow showers spreading into the Owens Valley by the afternoon.
Snow levels will hover near the valley floors in the Owens
Valley, and probabilities remain elevated for 2-5 inches of snow
across the northern Owens Valley, with even higher totals possible
along the Sierra foothills. Went ahead and converted the Winter
Storm Watch to an advisory for that region today and tonight, with
deteriorating conditions expected after dark as colder air moves
in and snow accumulations become more likely roadways.

As the weather system spreads east, a cohesive precipitation band
is likely to form with and spread across the southern Great Basin
and Mojave Desert. Snow levels will be falling to 4000-4500 feet
as the precipitation moves in, and may fall even lower on the
back edge of the precipitation shield. This will cause lower
elevation mountain routes including Mountain Springs, Mountain
Pass, and I-40 near Fort Rock to see snow accumulations and
potential travel impacts. Snowflakes or even a dusting of snowfall
are even possible around Red Rock Canyon and the highest
neighborhoods of the Las Vegas Valley by Wednesday morning.

Improving conditions are expected for most areas Wednesday
afternoon though terrain driven snow showers will persist in the
mountains with a cool and unstable airmass in place. A final
disturbance will move through Thursday and Thursday night with
additional shower chances, and snow levels will remain rather low
so there could be additional winter impacts. By Friday and into
the weekend, ridging will begin to rebuild with temperatures
trending closer to normal by Sunday.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Showers
and lower CIGS have moved out of the region, but gusty southwest
winds will remain through the day. Southwest winds 15 to 25 knots
with occasional gusts through 19z are expected, although there may
be some brief lulls at times this morning. The strongest winds are
expected this afternoon and evening where southwest gusts 30 to 40
knots are possible. Additional precipitation is likely late Tuesday
night, bringing another period of reduced CIGs.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Most of the
precipitation and lower CIGs have moved out of the region this
morning, although this will be short-lived as another system begins
moving into the area this afternoon and overnight. Gusty southwest
winds will remain over most areas through the afternoon with
southwest gusts 30 to 40 knots. Conditions will begin to deteriorate
this afternoon in the Owens Valley as precipitation begins to spill
over the Sierra. Snow levels with this next system will be much
lower and it is likely that snow levels will reach the Owens Valley.
Snow showers, low visibility, and gusty winds will impact KBIH late
this afternoon and evening along with gusty south winds to 30 knots.
Showers will spread east late afternoon and overnight with
deteriorating conditions across southern Nevada and northwest
Arizona.
