...Weak Winter System the End of the Week...Potentially Major
Winter Storm This Weekend...

After a couple of quiet and seasonably cool days, we`ll see the
return of winter weather the end of the week into the weekend.

Thursday-Friday:

Winds will become strong across Sierra ridgelines, with increased
breezes into lower valleys. A fast moving system will bring a
quick shot of snow, primarily to the Sierra north of Sonora Pass
and northeast California late Thursday into Friday. Up to 6 inches
of snow possible along the Sierra crest with periods of travel
difficulties. A few light showers may make it into western Nevada,
but overall much of western Nevada will remain dry.

Friday Night through the weekend:

Winds remain strong in the High Sierra with periods of stronger
winds surfacing in valley locations. Heavy Sierra snow with major
travel impacts possible throughout the entire weekend. Storm
totals will likely be measured in feet in the Sierra. Lower
valleys may see a rain/snow mix Saturday, otherwise plan on light
snow at all elevations into western Nevada with the worst travel
conditions expected to be Friday and Saturday nights.

Travel across the Sierra is not recommended this weekend. If you
choose to do so, make sure to have proper supplies and plan for
long delays.

...Significant Sierra Winter Storm this Weekend...

A significant winter storm is poised to impact the Sierra this
weekend with the potential for several feet of snow from Friday
night into late Sunday. Travel across the Sierra is not
recommended this weekend and may be impossible at times. If you
choose to do so, make sure to have proper supplies and plan for
long delays. Winds will remain strong and gusty in the High Sierra
with periods of stronger winds surfacing in valley locations.
Areas of whiteout conditions will be possible across the Sierra on
Saturday due to strong winds and heavy snowfall.

Lower western Nevada valleys could see spillover rainfall
Saturday as snow levels rise to 5000-6000 feet. Periods of
moderate to heavy rainfall during this timeframe could create some
nuisance flooding for urban and poor drainage areas. Snow levels
will then rapidly drop to all western Nevada valley floors by
Sunday morning which will provide the best chances for a few
inches snow accumulation and travel impacts across lower valleys.
