...Weaker Winter System Thursday night into Friday...
...Potentially Major Sierra Winter Storm this Weekend...
THURSDAY-FRIDAY: Weaker Storm, Sierra Pass Impacts Possible.
A fast moving and weaker storm will push through the Sierra
Thursday night into Friday morning. Travel difficulties across
Sierra passes are possible with up to 6 inches of snow
accumulation along the Sierra crest passes. A few light showers
may make it into western Nevada, but overall much of western
Nevada will remain dry. Winds will become strong across Sierra
ridgelines, with increased breezes into lower valleys.
THIS WEEKEND: Major Sierra Storm.
Chances for a major Sierra winter storm are increasing for this
weekend. Chances for heavy snowfall with feet of accumulation are
increasing across the Sierra from Friday night through late Sunday
night. 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.
Lower western Nevada valleys could see spillover rainfall
Saturday as snow levels rise to near 5000 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.
