Area Forecast Discussion
National Weather Service Sacramento CA
954 PM PST SUN JAN 3 2016

.SYNOPSIS...
Unsettled weather continues for the week with several systems
moving through the area. Rain and mountain snow is likely from
time to time, especially later Monday into Tuesday and later
Wednesday into Thursday.

&&
.DISCUSSION...
Updated forecast to push back timing for showers overnight.
Current radar trends and short term models keep overnight rain
mainly along the coastal range with the main band not progressing
into the valley until mid-morning. Snow should begin over the
Sierra around noon. Skies will remain cloudy with light winds
overnight.

&&

.PREVIOUS DISCUSSION...
Pacific low continues to approach the coast this afternoon with
light showers across western Shasta County south across the
Coastal Range and into the Bay area. Precipitation amounts over
the Coastal Range from the past 12 hours range from a few
hundredths to around a quarter of an inch. Expect showers to
continue in these areas for the rest of the day. Another wave will
move through tonight into the day Monday with showers possible
across much of the area. Amounts will be light with a few inches
of snow possible above 5000 feet.

Wetter weather is expected late Monday afternoon through Tuesday
as trough moves onshore. Precipitation will be more widespread
with this storm as it has a healthy Pacific moisture tap to work
with. Heaviest precip expected on Tuesday and will likely impact
at least the morning commute. Totals will range from a half inch
to 2 plus inches. Cannot rule out a few thunderstorms Tuesday
afternoon, generally west of Interstate 5 as models are showing a
bit of instability as trough passes through. Breezy southerly
winds will also accompany this system. Snow levels will hover
between 4500-5500 feet with moderate accumulations likely near
pass levels. This will likely cause some travel headaches with
delays and chain controls. Have issued a winter storm watch from
00z Tues - 06z Wednesday for Lassen Park and western slope of
Sierra Nevada. 6-12 inches expected near pass levels with up to 2
feet at highest peaks.

Some showers may linger into Wednesday but additional accumulations
will be light ahead of next system that will approach the the area
later Wednesday.

CEO
&&

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)

Precipitation will continue through Thursday with valley rain and
mountain snow above 3500 ft. A high pressure ridge over the
Eastern Pacific will move into the West Coast on Friday causing
shower activity to taper off throughout the day. There is still a
slight chance of rain/snow, but most places across interior NorCal
may get a break in precipitation that day. By early Saturday
morning, the 4th storm wave this week is forecast to move into
NorCal bringing wet weather with snow levels around 3000-4000 ft.
