AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1027 AM PST Thu Dec 5 2013

.Synopsis...
A cold air mass will result in hard freeze conditions tonight
across the Central Valley. A weather system will bring widespread
precipitation starting over parts of the region Friday evening
through Saturday. Heavy accumulating snow for the mountains,
significant snow in the foothills, and potentially some accumulating
snow down to the valley floor across portions of the Sacramento
Valley. A wet snow/rain mix is possible for rest of the Sacramento
Valley Friday night into early Saturday.

&&

.Discussion...
Northern California continues to reside in cold, dry northerly
flow on the backside of a broad trough over the western states.
Overnight temperatures plummeted under clear skies and light winds
and widespread sub freezing temperatures were observed in the
valley this morning. Temperatures ranged from the upper teens near
Chico to near freezing in the vicinity of Redding. High
temperatures for this afternoon will be around ten degrees below
normal under sunny skies. Hard freeze temperatures in the valley
again tonight. Fewer clouds are expected tonight than previously
forecast which will strengthen radiational cooling overnight.

Model guidance has delayed the onset of tomorrow's system by
around six hours. This will push the heaviest precipitation from
tomorrow afternoon into the late evening/overnight period. This
system in itself is quite cold and, with a cold arctic air mass
already in place, snow levels will drop drastically. Guidance is
not shying away from distributing snow through much of the Sacramento
valley with the eastern half of the valley looking the most
promising. Furthermore, the latest NAM12 brings a rain/snow mix
as far south as Fresno on the east side of the San Joaquin valley.
This storm is working with a modest moisture tap but will be
extremely efficient at generating snow. Snow to liquid ratios
could be as high as 20 to 1 in the high Sierra Nevada. 16 to 1
ratios are forecast in the foothills. This quick moving storm will
exit into the Great Basin later Saturday and leave behind an
immensely cold air mass.

This extremely cold air will lead to hard freeze conditions again
in the valley Saturday night into Sunday morning where temperatures
could drop to the mid teens in some sheltered locations. These
extreme temperatures could be kept in check by northerly winds in non
sheltered locations however sub freezing valley temperatures are
very likely with these low 850mb temperatures.

The forecast package will be updated to reflect the slower timing
of the storm as well as tweaks to overnight temperatures and snow
amounts/coverage.

.Previous Discussion... Cold dry northerly flow continues over
Norcal this morning on the backside of trough over the Rockies and
Great Basin. This pattern is causing widespread hard freeze
conditions over most of the area. Many locations are approaching
record low temperatures in the low to mid 20's. Only a modest warm
up Today despite sunny skies with valley locations topping out in
the mid to upper 40's which is about 10 degrees below normal. Very
cold again tonight with hard freeze conditions for most areas once
again with readings falling into the low to upper 20's for
valleys.

Disturbance currently over the Yukon will drop south in the
northerly flow and deepen over the pacific northwest on Friday.
The system will continue to strengthen as it drops south and pulls
a shot of Pacific moisture into Norcal Friday night. Models have
slowed the timing of this system by a few hours and it now appears
the heaviest precip will occur Friday night/early Sat morning.
Although...moisture with this system is not particularly deep it
will be a very efficient rain/snow maker given strong cooling
aloft along with good jet dynamics for lift. Given cold atmosphere
already in place and cold origin of the system there will be very
low snow levels...possibly down to the valley floor at times. Have
raised precip/snow amounts over the mountains and expect total
snowfall 12 to 24 inches at pass level with snow rates over an
inch an hour likely. Will continue all Winter storm watches.
Overall confidence in this storm is increased given good model
agreement.

The storm system will move into the Great Basin area late Saturday
with precip diminishing. Dry and cold northerly flow will develop
behind the system with widespread hard freeze conditions again
likely Sat and Sun mornings.

&&

.Extended Discussion (Monday through Thursday)

Dry northerly flow aloft will persist into early next week,
bringing continued cold temperatures across the region. Lows will
remain in the 20s across much of the Central Valley, with single
digits and teens over the higher elevations.

Medium range models are similar in building high pressure from
the Eastern Pacific into Interior NorCal by the middle of next
week for a slow warming trend. Forecast confidence lowers toward
the end of the extended period as model solutions diverge. The
ECMWF is the most bullish in bringing a storm system through the
region, whereas the GFS and GEM are weaker and differ on track. As
a result, the long-range forecast relies heavily on climatology.

Dang

&&

.Aviation...

VFR conditions persist across interior NorCal. Light north winds
at TAF sites will transition to light southerly flow overnight
into Friday morning. High clouds will increase late tonight ahead
of a low pressure system due to impact the region Friday.
