AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
956 AM PST Tue Dec 9 2014

.Synopsis...
Mainly dry across Interior Northern California today into early
Wednesday. Strong Pacific storm impacts the area Wednesday into
Friday bringing heavy precipitation including significant mountain
snow and strong damaging winds.
&&

.Discussion...
Decreasing cloudiness overnight allowed for an extensive area of
fog to develop in the Central Valley. Surface observations showing
impact area is from the Southern Sacramento area southward into
the San Joaquin valley. Heavy fog areas will be slow to clear with
extensive mid and high cloudiness above. Meanwhile a frontal
system is pushing into the PacNW with southern portions bringing a
slight chance of light precip mainly over the Coastal range and
mountains of Shasta county today into early evening. Areas of
valley fog expected to develop again tonight into Wednesday
morning.

Models showing strong cyclogenesis off the West Coast Wednesday
as 160+ kt jet approaches and surface low rapidly develops and
deepens near 40N 130W. This system will also be taping into a deep
moisture plume with blended TPWs showing values up to around 1.5
inches. Progs differ with how quickly surface low deepens and
progresses with GFS/ECMWF-HiRes quicker to deepen the low and
progress it towards the southern Oregon coast early Thursday.
Winds will significantly increase Wednesday evening over Interior
NorCal as pressure gradient tightens and front approaches. With
surface low deepening below 980 mb Wednesday night, strong low
level southeasterly jet results over the Central Valley. Both
NAM/GFS showing large area of 925 mb winds around 60 to 65 kts. By
12z Thu KCEC-KSAC model surface gradient near 15-17 mbs and GFS
MOS guidance (stronger than NAM due to faster progression of
surface feature) indicating sustained surface winds in the Central
Valley of 35 to 45 mph possible with gusts 60 to 70 mph. The
strongest winds look to be between 06z and 18z Thu with strong
potential for power outages, downed trees and possible property
damage.

Precip begins over western portions of Interior Northern
California Wednesday afternoon and then spreads over all of
Interior NorCal Wednesday night. Heavy precip over the Coastal
range and Shasta basin overnight Wednesday shifts into the Central
Valley and Sierra Nevada Thursday as the front moves through. PWS
depicted around 1.25 inches over the Central Valley Thursday and
near an inch for the mountains. Strong S-SE flow enhances precip into
the Shasta basin and western portions of the Sacramento Valley
into the Coastal Range. Orographic flow is not quite as favorable
into the Northern Sierra Nevada but models suggest secondary low
developing along the baroclinic zone which could cause the front to
stall along southern portions of the CWA Thursday afternoon into
night. Snow levels will generally be above 6500 feet through
Thursday then lower Thursday night as the colder air moves inland.

Showers and isolated thunderstorms possible Friday as upper trough
moves through. Snow levels drop to around 4500 feet Friday. Storm
total QPFs for late Wed into Friday look to be around 2 to 4
inches in the Central Valley and around 3 to 6 inches in the
foothills and mountains. There is a high potential for localized
flooding with this storm.

PCH

&&

.Extended Discussion (Saturday through Tuesday)

The trough shifts to the east on Saturday as an upper level ridge
moves onto the West Coast. This should bring a break in
precipitation for most areas on Saturday and Saturday night but
lingering showers are possible over the mountains during the day.
Sunday should be a dry day across most of the area as the ridge
shifts east. Another low pressure will likely impact the area
early next week, though confidence is low in exact details. Next
week's system will not be nearly as strong as this week's.

Dang

&&

.Aviation...

Widespread IFR/LIFR conditions with dense fog across the Valley
south of KOVE until around 19z then improving to MVFR/IFR
conditions until 06z then becoming IFR/LIFR again. Along the Northern
Valley, isolated -SHRA may bring occasional MVFR conditions today.
A wet and windy storm storm bringing more significant precipitation
Wednesday afternoon into Thursday. Southerly winds will increase
during the day Wednesday ahead of the next system. Wind gusts 60
