.KEY MESSAGES...
* Wet and windy pattern commences this weekend, lasting into much
of next week. Expect impacts to holiday travel.
* Good potential for heavy rain Sunday with rises on creeks and
rivers, with a non-zero risk of heavy mountain snow Christmas
Eve and Christmas Day.
* Dry and with gusty winds most areas today, with light showers
and stronger winds tomorrow.
&&
.DISCUSSION...
* Impressive plumes of moisture coming off the Pacific into the
Sierra over the next 5-7 days, with Sunday and Christmas Eve/Day
the days to really watch with 30-60% chances of at least
moderate atmospheric river conditions (IVT > 500) making it into
the Sierra foothills, per CW3E charts. QPF amounts have trended
up especially for Sunday-Monday and Wednesday compared to NBM
guidance 24 hours ago. Snowfall trends mid/late next week are up
but only slightly. Wind potential has ticked up for Friday but
more notable rises for Sunday vs models 24 hours ago.
* Main unknowns are how far south the heavy rains will go this
weekend before pivoting back north Monday-Tuesday. Tahoe Basin
up into Lassen has the best chance of potential impacts from
heavy rain and rising creeks/rivers. Also how quickly will the
high rain- snow lines this weekend fall next week in time for
the Christmas Eve/Day precip peak. That will dictate heavy snow
potential in the Sierra and even down into the foothills of W
Nevada around the holiday. 25th and 50th percentile snowfalls
for mountain communities are zero but 90th is 7-15" each day
Wednesday-Thursday for places like Tahoe and Mammoth Lakes.
* Can`t forget about winds in this pattern. Friday looking rather
breezy with 50-80% odds of seeing gusts over 45 MPH along Hwy 395
communities from Mammoth to Reno and up into NE California. Sunday
is another day where if we see periods of shadowing, the winds
could kick up with 30-60% chances of those 45 MPH gusts at times.
Obviously the Sierra ridges will be howling, with 700mb winds
projected near 60 knots in the ICON deterministic model, so that
would easily yield 100+ MPH gusts for the higher terrain Friday
and again Sunday. Even today 700mb flow is near 50 knots so ridges
will be breezy.
* We`re entering a busy holiday travel period. Factoring in wind,
snow, and rain potentials - Saturday and Tuesday probably have
the best travel conditions. I`d probably stay away from Sunday
and Wednesday/Thursday due to heavy rain and snow risks,
respectively.
* The snowpack is in a sorry state not just in the Sierra but
across much of the west. We`ve had precip just not snow. NRCS
SNOTEL data showing the Eastern Sierra at or near record lows
for this time of year going back to at least the early 1980s.
The forecast pattern mid-late next week does allow for more cold
air to drop in with a deepening trough, such that any storms
Tuesday onward should have better snow potential for the
mountains. NBM showing the rain to snow cross-over at Donner
Pass and Mammoth Lakes is Monday evening or Tuesday morning
respectively, where snow is favored over rain in NBM
probabilistic guidance. But, one concern is it`s never really
"all snow" even Wednesday & Thursday - e.g. 55-65% chance of
snow p-type but 15-30% chance of rain...

.AVIATION...
* Main aviation weather issues next 24-36 hours center on wind,
with a strong W/SW flow aloft spreading across the region
Thursday & Friday. 700mb/ridgetop flow nearing 50-60 knots in
latest high resolution models.
* For sure we`ll have periods of LLWS for all airfields in the
Sierra and far W Nevada including RNO. Mountain wave turbulence
is also expected Thursday and Friday east of the Sierra.
* How much of this flow mixes down to the surface is the main
uncertainty. NBM guidance showing 30-50% chance of gusts over 30
knots on Thursday between 21z-03z, with 70-90% chance on Friday at
RNO/CXP/MEV, TRK/TVL, and MMH.
* A short lived wave of precip is also likely to affect flying
conditions on Friday during the day. Mainly in the mountain
areas from SVE to TRK/TVL with periods of MVFR-IFR in rain.
