Area Forecast Discussion
National Weather Service Sacramento CA
311 PM PST THU JAN 28 2016

.SYNOPSIS...
Wet storm moving in later tonight and Friday with high snow levels.
Snow levels lower Friday evening and Saturday with possible travel
issues over the Sierra. Periods of heavy rain and snow Friday into
Saturday over the West Slope Sierra Nevada.

&&.

.DISCUSSION...

Initial short-wave moving into the Pac NW has weakened the ridge
sufficiently and the Srn portion of the wx system has been able to
spread into the I-80/US-50 corridor before evening...faster and
deeper (farther S) than many of the models. This system will be
exiting the area this evening...only for the more wetter system
to follow closely on its heels on Fri.

Satellite imagery is showing a batch of moisture nearing 130W and
rapidly approaching the CA/ORE coast. This moisture is destined to
spread across norcal on Friday bringing periods of moderate to heavy
precipitation to Norcal. Significant moisture is associated with this
system with TPW values of nearly an inch and a half with some values
near 1.9 inches around 135W. This TPW plume (aka AR) is a +3
PW standardized anomaly with a return interval of once every 10 yr
and a small area outside the 30 yr climate occurrence as well.

A strong 150 kt jet will focus this +3 standardized anomaly PW plume
perpendicular/orthogonal into the W Slope Siernev with maximum large
scale ascent/topographic forcing from 12z Fri to 12-18z Sat. The GFS
6-hr averaged precip rates could reach .40-.50" over the W Slope Siernev
during this time. During the day on Fri...snow levels are forecast to
be high...then lower later Fri nite and Sat. The timing of the heavier
precip rates and higher snow levels bring a concern for the potential
for debris flows over the recent Siernev burn scars.

5H heights will lower behind the Fri wave as a broad trof begins to
develop over the NErn Pac. Cooler air from the Gulf of Alaska will
spread into Norcal Fri nite/Sat and lower snow levels to 4-5 kft. With
the bulk of the moisture over Zone 69...we will upgrade the winter
storm watch to a warning during this period with an advisory for
zone 68.

As the upper jet sags Swd into Socal...the broad trof will sharpen
and deepen along the coast on Sun. CAA will lower snow levels to
2-3 kft...possibly around 1500 ft over Shasta Co...with a cold and
unstable airmass resulting in a chance or scattered showers and
possible valley T-storms on Sun. Forecast soundings show
unidirectional flow which should inhibit shear profiles. NWly
flow may also result in some partial clearing during the day
especially on the W side of the Valley. JHM

.EXTENDED DISCUSSION (Monday THROUGH Thursday)

Extended period characterized by uncertainty as major differences
remain between ECMWF and GFS (GEM most closely aligns with GFS).
Overall pattern should feature upper level ridging with weak waves
attempting to drop SE into NorCal every few days. GFS and GEM
scenarios would keep most of NorCal dry into mid-week with just a
few showers across the northern mountains as moisture remains
shunted offshore. ECMWF on the other hand is wetter with more
widespread precip across NorCal for Tuesday thru mid-week.
Therefore, have not made major changes to the extended until
differences are better resolved. ¯\_(ツ)_/¯ Regardless, below
normal temperatures will likely continue.

CEO
&&

.AVIATION...

Showers are already forming across the Valley this afternoon with
more widespread light rain expected after 06Z Friday. MVFR
conditions are expected for tomorrow throughout the Sacramento
Valley although isolated IFR conditions cannot be ruled out.
Southerly winds will be picking up tonight and are expected to be
gusting 20-25 KTS tomorrow. Wilson
