A couple of storms are on tap for the weekend that may result in
travel disruptions along the Sierra, aviation impacts, and
recreational hazards. The Saturday storm will be a quick hitter
with lighter precipitation, while the Sunday storm will be much
more robust and linger through early next week.

Saturday: This initial storm moves through quickly with gusty
winds and precipitation beginning by around midday. The system
quickly exits the Sierra and western Nevada by Saturday evening.
Light rain, or a mix of rain and snow above lower valley floors,
is possible in western Nevada, with a modest snowfall in the
Sierra. Travel impacts from snow in the Sierra and for northeast
California are expected to increase Saturday night.

Sunday: The stronger of the two storms begins to move in early
Sunday morning. Plan for heavier snow in the Sierra with periods
of white out conditions possible due to gusty winds, with aviation
turbulence, low level wind shear, and periods of rain and snow
showers for western Nevada. Wind gusts 30 to 40 mph, locally
to around 50 mph in wind-prone areas, will be possible for valley
locations with wind gusts to around 90 mph for exposed Sierra
