Area Forecast Discussion
National Weather Service Sacramento CA
927 AM PST Sat Jan 7 2017

.Synopsis...
Light to moderate precipitation with snow levels down to the
northern Sacramento Valley in the morning, rapidly rising in the
afternoon. Very heavy rain and flooding concerns arrive Sunday
into Monday. Another wet storm Tuesday into Wednesday with
continued flooding concerns and significant mountain snow.

&&

.Discussion...
Moderate precipitation has spread across the forecast area. Rain
amounts so far are generally around a third to three quarters of
an inch. Valley rains will decrease in intensity this afternoon,
then increase again this evening and overnight. Heaviest rain is
expected during the day Sunday. Snow levels in the Sierra are
rising, with snow falling down to 4000 feet, and reported to be
already rising to round 6000 feet.

Northerly winds in Shasta County have brought cold air drainage
and along with evaporative cooling have brought low snow levels
this morning. A mix of wet rain and snow briefly reached as low as
Red Bluff, around 350 feet, with some snow accumulating on the
grass around Cottonwood (elevation 420 feet). Moderate
accumulating snow is falling in around Redding. Snow will continue
through the morning, with snow levels rising rapidly this
afternoon. A Winter Weather Advisory remains effect, and will
be updated to expand the area southward.

Gusty winds have remained mainly over the northern San Joaquin
Valley this morning, with sustained winds up to around 26 mph at
Stockton at 8 am. Winds gusting to 20 mph at Mather, while
Sacramento Executive and International Airports have remained
calm. Will likely cancel the wind advisory later this morning.
Stronger winds are expected Sunday.

&&
.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)

Westerly flow aloft will continue to bring moisture through
northern California going into the extended period. Model
agreement starts to fade but there is a general agreement in this
westerly flow and orographics should ensure at least moderate
precipitation over the Sierra. Temperatures should come in around
normal for this time of year. Models really begin to diverge by
next Thursday. ECMWF digs a low in over northern California while
GEM puts upper ridging over the Great Basin. GFS keeps a more
zonal flow over the region. Any of these solutions could allow for
continued precipitation over the CWA but only the ECMWF could
bring a continuation of the heavier precipitation that is expected
earlier in the week. More amplified ECMWF solution would bring
a break in precipitation threat Friday while GFS and GEM continue
to feed moisture into the north state. Chance pops continue to be
best bet at this time. Although wet pattern may continue into
next weekend...at this time models are hinting at at least a
reduction in precipitation amounts. Snow levels remain moderate
through the extended period.

&&

&&

.AVIATION...

IFR ceilings and visibilities next 24 hours as a Pacific frontal
system moves. Occasional LIFR in heavier showers. Sierra snow
levels 2000 to 4000 feet this morning rising quickly to 7000 to
8000 feet after 00z. Light north winds in the northern Sacramento
valley turning southerly after 00z Sunday. Otherwise southerly
winds 10 to 20 mph with gusts to 40 mph over the Sierra and in the
northern San Joaquin valley.
