Synopsis 17 121 pm.

Widely scattered showers will move through the region today with
low snow levels. Temperatures will remain well below normal
through the week and there is a chance of another storm late
Wednesday through early Friday.

Short term (tdy-wed) 17 250 pm.

A fast-moving weather disturbance and surface cold front was
moving through southwestern california this afternoon with plenty
of rain and snow showers with snow levels around 3000 feet or so.

The rain and snow showers will taper off later today into this
evening, except persist on the north mountain slopes for a while
tonight. In addition, strong and gusty NW winds will move into the
region behind the cold front through this afternoon and evening,
especially for the central coast, sba county south coast, and
across many of the foothills and mountains. Gusty mainly sub-
advisory level west to northwest winds should affect much of the
rest of the region through this evening as well.

Several inches of snow accumulation is expected through tonight
mainly above 3000 feet across the region, with minor accumulations
possible as low as 2000 feet. Lower elevations that should get
some snow accumulation include the foothills of the antelope
valley, cuyama valley, and the foothills of the slo county
interior valleys. The mountains will see the most snow
accumulation, with totals up to 8 inches not out of the question
for the vtu county mtns above 4000 feet. Interstate 5 over the
grapevine is also expected to be impacted by the snow, with total
accumulations there of 2 to 4 inches possible. The combination of
accumulating snow and gusty winds will cause poor visibilities and
icy road conditions around and just below the grapevine this
afternoon and evening, resulting in major impacts to travel in
this area. In addition, other low elevation passes will likely
experience snow or icy road conditions, including highways 14 and
138 through antelope valley and soledad canyon, highway 33 in the
ventura county mountains, and highway 166 through cuyama valley.

Due to the snow and gusty winds, a winter weather advisory remains
in effect for all the mountains except the santa monica range, and
in the slo county interior vlys, cuyama vly and the antelope vly
mainly for the foothills through late tonight. Please see the
latest winter weather message (laxwswlox) for further details.

Rainfall estimates through this evening with this system are
expected to range between 0.10 and 0.50 inch, with the highest
amounts across slo and sba counties, as well as the north facing
slopes of the mountains where orographic lift will aid with shower
development.

A large and pretty deep upper level trof will move into southern
ca tonight into Mon then move E of the region Mon night and tue.

It looks like a mainly inside slider upper level trof will move
down the pac NW coast Tue night and into ca on wed.

There may be a few leftover north slope snow showers Mon morning,
otherwise skies should gradually clear in all areas thru mon
afternoon. Mostly clear skies should prevail across the region mon
night through Tue evening, followed by some increasing clouds for
later Tue night into wed. There is also a slight chance of
showers for parts of slo sba counties by Wed afternoon.

Gusty mainly northerly winds can be expected Mon and Mon night,
especially for the mtns and foothills, altho by early Tue morning
gusty N to NE winds will be possible for wind-prone vlys and
perhaps some coastal areas areas of vtu l.A. Counties. Advisory-
level gusts cannot be ruled out for the sba county S coast and
mtns Mon evening as well.

Temps across the region are expected to remain well below normal
in all areas. Highs for the coast and adjacent vlys are expected
to reach only into the 50s each day, while normal highs in these
areas for this time of year are generally in the mid 60s to near
70. It will be quite cold Mon night and Tue night, with areas of
frost likely for many sheltered areas away from the immediate
coast, and freezes possible in the slo county interior vlys,
cuyama vly and antelope vly. For Mon night and possibly Tue night,
there may be the need for frost advisories in a few areas, such as
the vtu county vlys and inland areas of the central coast.

Long term (thu-sun) 17 252 pm.

The upper level trof that is forecast to move into ca Wed will
dig into southern ca Wed night and thu, with 500 mb heights
lowering to around 534 to 536 dm, while 1000-500 mb thicknesses
lower to around 528 to 531 dm. This would suggest snow levels
could get as low as 2000 to 2500 feet, or locally lower in any
heavier showers. This system will bring a chance of rain showers
to lower elevations, with snow showers becoming likely for the
mtns. Some of the higher hills adjacent to the coast and vlys
could have some snow showers with this system as well. Any
accumulating snow would likely be above 2500 feet, which means
more possible travel impacts for interstate 5 over the grapevine
wed night into thu. The GFS moves the upper level trough out
quicker than the ec Thu night, but went with a model blend and
kept a slight chance of rain and snow showers in the forecast for
most areas through Thu night.

The upper trof moves E on fri, with either flat upper ridging
over SRN ca (ec) or broad upper level troffiness over the region
(gfs) for Sat and sun. The GFS has pcpn just N of the forecast
area over the weekend, and will keep the forecast dry over swrn ca
during that period. Skies will be mostly clear across the region
for fri, then become partly cloudy over the weekend.

Temps will be well below normal again on thu, with highs only in
the lower to mid 50s for most coast and adjacent vlys, then slowly
warm Fri into the weekend to just a few degrees below normal by
sun. There could also be areas of frost and some freezes in the
sheltered locations away from the immediate coast Thu night into
early fri, otherwise nighttime lows will continue below normal in
all areas through the extended period.

Aviation 18 0032z.

At 0005z at klax... There was no marine inversion present.

Scattered showers will continue across the region through early
evening as the cold front has pushed eastward of la county.

Showers with potential ifr CIGS vsbys will continue at times
across interior sections. Gusty west to northwest winds developing
across most TAF sites behind front continuing into evening hours,
with local llws and areas of mdt uddfs.

Lax... Moderate confidence in the 00z taf.VFR conditions should
generally prevail through much of the period, however could see
brief MVFR conditions if an isolated shower develops through 03z.

Strong west to northwest winds behind front through this evening.

Northerly winds are expected to develop late tonight or early
Monday morning, with only a 20 percent chance of exceeding 10
knots.

Kbur... Moderate confidence in the 00z taf.VFR conditions should
prevail through much of the TAF period, however could see brief
MVFR conditions if an isolated shower develops through 03z.

There is a 30% chance of W to NW winds sustained at 20 kt with
gusts as high as 30 kt between 01z and 09z.

Marine 17 1005 am.

For the outer waters, moderate to high confidence in the
forecast. Winds will increase to gale force this morning, then
persist at those levels through late tonight. SCA level conds are
expected late tonight through thu, with the possible exception of
a period of late Mon night thru Tue where conds may be below sca
levels.

For the northern inner waters zone (pzz645), moderate to high
confidence in the forecast. SCA winds and seas are expected
through late tonight. There is a 30% chance that winds could reach
gale force late this afternoon and evening. There is a 30% chance
of SCA level winds Mon afternoon and evening. SCA conds are
likely late Wed thru thu.

For the sba channel and southern inner waters zone (pzz650, pzz655),
moderate confidence in the forecast. Winds are expected to
increase to gale force this morning, then continue thru late
tonight. Winds will be strongest across the western sections.

There is a 20% chance that winds will remain below gale force in
most areas. SCA conds are expected Mon and early Mon night, then
are likely again late Wed thru thu.

A large long period NW swell will affect the waters this weekend.

The combination of large swell and large steep wind waves will
create very hazardous seas across much of the coastal waters
through mon.

Beaches 17 1010 am.

Large long period northwest swell will bring high surf to the
central coast, and the west facing beaches of l.A. And ventura
county thru this evening.

On the central coast beaches, surf of 9 to 13 ft is expected to
slowly subside later today, falling to 6 to 9 ft this evening.

Surf will be highest on west and northwest facing beaches.

On the beaches of ventura l.A. Counties including catalina island,
surf of 6 to 9 ft will slowly subside later today, falling to 4 to
6 ft this evening. Surf will be highest on west facing beaches.
