  showers around 12am. The next shot of snow arrives by 4am-7am
  and continues through early Wednesday morning.

* Snow Totals through Wednesday:

     Tahoe Basin: 2 to 3 feet, highest on west shore & Alpine
county, Above 7k feet: 3 to 5 feet.

     Mono County: 1 to 3 feet along and west of US-395, 3 to 5 feet

* Winds: Plan on strong winds through Tuesday night. Gusts of 50-60
  mph are likely (>60%) for wind prone areas in Mono County, with
  other areas in the Sierra gusting as high as 40-50 mph. Otherwise,
  ridgetop gusts will likely top 100 mph. Gusty winds will create
  areas of blowing snow and low visibility at times.

----------------------------------------------------

WESTERN NEVADA:

* Bottom Line Up Front: Rain/snow mix into this evening with light
  accumulations for elevations near and above 5500 feet. Main
  impacts start this evening for northwest NV and late tonight for
  western NV as snow levels drop to all valley floors. Plan on
  hazardous travel midday Tuesday through the Wednesday AM commutes.

* Changes: Winter Storm Warning in effect for Reno, Carson City,
  Minden locales Tuesday.

* Timing: Rain or a rain-snow mix will continue for most areas, with
  some breaks especially from I-80 southward this afternoon. There
  could be some light snow accumulations after 6pm tonight,
  especially for areas I-80 northward. The heaviest snow spreads
  across most areas from Tuesday through Wednesday morning.

* Snow Totals: This evening, light accumulations (1" or less)
  below 5500 feet, with 1-3" of wet snow above 5500 feet.
  Through Wednesday AM, at least 4" down around the Reno-Carson
  metro areas and for northwest NV, and 6-12+" for foothills above
  5000 ft. For west central NV, up to 3" with around 6" for
  higher terrain.

* Winds: Southwest wind gusts up to 45 mph are likely (>70%), with
  higher 50+ mph gusts in wind-prone areas. Periods of blowing snow
  possible with lower visibility late tonight into Tuesday.


----------------------------------------------------

By Wednesday, there will still be some residual snow showers ongoing
in the Sierra, but we will start to see some clearing for areas of
western Nevada. Although it will be a very brief break. Another
system kicks in on this storm`s heels bringing more snow
Thursday-early Friday. Friday and Saturday will be quite chilly,
but offer a bit of a break between the storms. There are signals
for another storm by next weekend, so it appears we have finally
entered a more winter-like pattern with an open storm door.
