ASR/KITTELL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
948 PM PST Wed Dec 14 2016

.SYNOPSIS...
A Pacific storm system will bring widespread rain, possible
mountain snow and gusty winds to the region Thursday through
Friday morning. A chance of showers and mountain snow showers
will linger through Friday evening. Dry and cool conditions will
then prevail through the weekend.

&&

.UPDATE...

In the immediate short term, main issue is the development of
stratus and fog across the coastal plain. Current surface
observations indicate low clouds/fog rather extensive along the
Central Coast and patchy south of Point Conception. Based on
current surface reports, there are some pockets of dense fog which
will continue overnight, but should not be widespread enough to
warrant type of advisory. So tonight should be a mostly cloudy
period due to the combination of low and high clouds. Otherwise,
no significant issues in the immediate short term.

Quick look at initial 00Z model data indicates no significant
changes to previous forecast thinking. Powerful cold front will
sweep across the area Thursday and Thursday night, bringing
moderate to locally heavy rainfall as well as strong winds.
Previous discussion (below) handles the details well at this
time.

&&

.SHORT TERM...(WED-SAT)

High pwat content air mass headed our way showing up well on water
vapor imagery just to our west. This will provide the source
material for our moderate to heavy rain event Thu into early Fri.
Everything pretty much on track with the timing and amounts. The
only difference today was a slightly slower departure of the rain
out of LA County Friday morning on the NAM which could lead to
slightly higher totals there. Otherwise, it's still not looking
favorable for convection. But given the high moisture content, very
warm air mass (freezing levels 9-10kt ft), and good orographic
enhancement this will be a very efficient rainfall producer and
usgs thresholds could be met for debris flows in burn areas even
with just steady non-convective heavy rain.

Peak time for the rain (as it seems it often is with rain events
here) will be during the overnight hours. Still a soggy morning commute
expected in LA and Ventura counties but unless the slower NAM is
correct we should be seeing a significant decrease in shower
activity by mid to late morning.

Most post-frontal shower activity should be confined to the
mountains and Central Coast as northwest flow takes over, but
can't rule out a stray shower just about anywhere. Snow levels
will be lowering through the day but accumulations should be
minimal as the bulk of the moisture has moved east by that time.

The upper level trough will move through the area Friday night but
the only moisture left over at that point will be near the Kern
County line up against the north slopes of the mountains. This
likely should be strong enough to squeeze out a few more showers
with much lower snow levels, down to perhaps as low as 3500 ft
Saturday morning but accumulations not likely to amount to much.
Still, travelers headed up through the Grapevine Saturday morning
should pay attention to the road reports before departing.
Otherwise, Saturday will be dry and cool with some locally breezy
north to northeast breezes.

.LONG TERM...(SUN-WED)

Dry and cool through at least Monday as a cold inside slider
follows the previous trough and slides all the way south into nrn
Mexico Monday afternoon. This will provide some upper level
support for gusty Santa Ana winds Sunday-Tuesday, though mostly
Monday/Tuesday with the GFS now showing a -6mb LAX-DAG gradient
Monday morning and 30-50kt around 850mb and decent cold air
advection. At this point this would add up to an advisory level
Santa Ana wind event but cool temps with thicknesses in the mid to
high 530s Monday. A modest warming trend with decreasing winds
Tuesday into Wednesday.

&&

.AVIATION...15/0547Z...

At 0530Z, the marine inversion at KLAX was based around 500 feet.
The top of the inversion was 1500 feet with a temperature of 18
degrees Celsius.

Overall, low confidence in 06Z TAFs. Low clouds/fog will continue
to expand overnight, but low confidence in timing or flight
category changes. On Thursday, moderate confidence in MVFR CIGs
prevailing at coastal/valley TAF sites through the evening.
Approaching cold front will bring steady rain to the Central Coast
Thursday afternoon and into the LA Basin Thursday night. CIG/VSBY
restrictions will likely jump from category to category Thursday
and Thursday night.

KLAX...low confidence in 06Z TAF. High confidence in return of
CIG/VSBY restrictions overnight, but low confidence in timing
(+/-2 hours of current 08Z forecast) or flight category (CIGs
could range from LIFR to MVFR). There is a 40% chance of
southeast winds around 10 knots Thursday evening (after 02Z).

KBUR...low confidence in 06Z TAF. High confidence in return of
CIG/VSBY restrictions overnight, but low confidence in timing (+/-
3 hours of current 07Z forecast) or flight category (CIGs could
vary from LIFR to MVFR).

&&

.MARINE...14/815 PM...

For the Outer Waters, moderate confidence in current forecast.
Cold front forecast to move across the area on Thursday will bring
increasing southerly winds with moderate confidence in winds
reaching Gale Force levels Thursday afternoon/night. Behind the
front Thursday night and Friday, winds will shift to the northwest
with a good chance of Gale Force winds continuing into Friday
night. For Saturday into early next week, moderate confidence in
winds continuing around Small Craft Advisory (SCA) levels.

For the Inner Waters, moderate confidence in current forecast. For
the waters north of Point Sal, moderate confidence in southerly
winds reaching Gale Force levels late Thursday afternoon through
Thursday night. SCA level winds are expected on Friday then winds
will be below SCA levels Saturday into early next week. For the
waters south of Point Conception, low confidence in southerly
winds reaching Gale Force levels Thursday night/Friday morning.
During the day on Friday, winds will shift to the northwest with a
good chance of Gale Force winds. By Saturday/Sunday, winds are
expected to be below SCA levels, but SCA level northeast winds are
possible on Monday.
