Area Forecast Discussion
National Weather Service Sacramento CA
305 AM PDT Fri Mar 13 2020

.Synopsis...
Dry and mild weather today. Cold weather system will bring
widespread rain and mountain snow this weekend into next week
with mountain travel impacts and low snow levels.

&&

.Discussion...
Short-wave ridging, between the low over the Desert Southwest and
the deep trough upstream off the coast of BC, continues to provide
clear skies across the forecast area early this morning. North to
east surface pressure gradients continue to result in locally
breezy north to northeast wind gusts (20-30 mph) across the
northern Sacramento Valley and surrounding terrain. Current
temperatures range from the mid 20s to lower 30s in the colder
mountain valleys, to the mid 40s to mid 50s (except lower 60s over
the breezier north end of the Sacramento Valley) across the
Central Valley.

Ridging breaks down today ahead of the upstream deep trough.
Temperatures will cool around 5-10 degrees compared to today as
flow reverses to onshore and synoptic cooling begins.

The trough closes off into a deep closed low by tonight and will
drift slowly southward off the coast through the weekend. This
anomalous cold upper low will bring the potential for widespread
precipitation, heavy mountain snow, gusty winds, and significantly
cooler temperatures this weekend into early next week. Showers
will develop over the higher elevations this evening, then
increase and spread across the region into Saturday morning as a
cold front pushes south through the area. Steady light to moderate
precipitation will continue Saturday into Sunday before becoming
more showery on Sunday.

Pattern is favorable for significant snowfall accumulation across
the west slopes of the northern Sierra where ensembles continue to
favor several feet of snowfall accumulation at KBLU. Snowfall
accumulation of this magnitude will lead to potentially major
travel impacts across the Sierra over the weekend.

In addition to widespread precipitation, thunderstorm development
will be possible Sunday afternoon as instability develops. Small
accumulating hail is possible with any thunderstorms.

With the upper system over the West, temperatures will remain 5
to 15 degrees cooler than normal over the weekend.

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)...
A broad long wave trough will dominate our weather through
midweek. This means unsettled and cooler weather will be the main
features, with precip chances lingering throughout at least
Wednesday. The mountains still have the best chances of seeing
additional precipitation; however, some light accumulating rain
isn't out of the question for the Valley and foothills. By
Thursday, deterministic model data split suggesting that we could
see a brief period of ridging. NBM guidance leans to a wetter
solution keeping some precip chances over the mountains. Overall,
expect to see partly to mostly cloudy skies and cooler than
average temperatures are expected next week, with most highs
running about 5-15 degrees below average.

.AVIATION...
VFR conditions are expected for the next 24 hours. Breezy winds
return after 18Z ahead of an approaching winter storm. Chances for
mountain rain and high elevation snow move in later today, with
the Valley and foothills slowly joining in after 06Z.
