Synopsis 20 115 pm.

Today will be cloudy with a chance of showers and mountain snow
as another storm system moves into the region. The chance of rain
and snow with windy conditions lasts through Thursday, and cold
temperatures could lead to snow at lower elevations. Dry weather
is expected by Friday, and temperatures will gradually warm into
next week.

Short term (tdy-sat) 20 156 pm.

Cold upper low dropping south along the west coast has already
generated some light showers across the far western portion of
the forecast area, mainly west of a line from goleta up through
interior slo county. Expecting these to spread south and east
through the evening, though again the downsloping effects from the
northwest flow over the transverse ranges will dissipate at least
some of the precip, especially western ventura county and
southeastern sb county. But even in those areas there should be
some light precip that may or may not result in measurable rain.

This pattern to continue through Thursday with the added potential
of thunderstorms as the air mass becomes slightly unstable. These
could generate some brief heavy downpours with small hail or
graupel just about anywhere but given the overall lack of moisture
with this system we're not expecting rain rates to pose any issues
for burn areas.

The biggest impact locally will be the extremely low snow levels
and likely significant delays and closures of major roads through
the mountains tonight and Thursday, including interstate 5
through the grapevine and possibly even highway 14 from santa
clarita to the antelope valley. Some of lower highways could even
be impacted at times including highway 101 through cuesta pass in
slo county and highway 154 through san marcos pass in sb county.

Interstate 5 likely to be the biggest concern due to the
combination of strong northwest flow pushing the moisture up the
north facing slopes and very cold temps. Could see 3-6" of snow
accumulation at pass level. Thicknesses bottom out at around 526dm
which if true could result in snow down to 1000' or even slightly
lower. A winter weather advisory is in effect for all the
mountains and interior valleys through Thursday evening.

Showers expected to taper off by Thursday night with dry but cold
weather Friday. Will be issuing a freeze watch for late Thursday
night into Friday morning for the central coast and the valleys of
la ventura counties as clearing should happen early enough for
temps to drop to near or below freezing in many areas.

Another cold night Friday night followed by a cool but slightly
warmer day Saturday but with temps still a good 5-10 degrees
below normal in most areas.

Long term (sun-wed) 20 205 pm.

Pretty quiet through the middle of next week. Temps will remain
below normal through the early next week but then should be
getting very close to normal by Tue Wed as a ridge of high
pressure sets up along the west coast that should last at least
through Friday.

Aviation 20 1849z.

At 1800z, there was no marine inversion at klax.

Moderate confidence in 18z TAF package. A cold and unstable air
mass will bring bkn CIGS and a threat of showers to all sites from
late this morning through tonight. Shower threat will start north
of point conception late this morning then spreading to areas
south of point conception from mid-afternoon through tonight. Cigs
are generally anticipated to remain atVFR level (bkn040-060) but
there is a 30% chance of MVFR CIGS this afternoon through
tonight. Additionally, there will be some gusty westerly winds
along the coast and across the antelope valley this afternoon and
tonight. Another caveat will be a threat of snow reaching the
antelope valley floor, and this may be added to the TAF sites
there.

Klax... Overall, moderate confidence in 18z taf. There is a 30%
chance of MVFR CIGS after 22z with chance of showers after 02-04z.

East winds around 6 knots will continue through 20z. Gusty west
to northwest winds will develop after 20z.

Kbur... Overall, moderate confidence in 18z taf. There is a 30%
chance of MVFR CIGS after 22z with chance of showers after 02-04z.

Marine 20 136 pm.

For the outer waters, moderate to high confidence in current
forecast. High confidence in small craft advisory (sca) level
northwest winds today through Thursday night with a 70% chance
of SCA level winds continuing through Friday evening. There is
a 30% chance of gale force gusts this afternoon through Thursday
evening. For Saturday and Sunday, moderate confidence in SCA level
winds continuing.

For the inner waters north of point sal, moderate to high confidence
in current forecast. High confidence in small craft advisory (sca)
level northwest winds during the afternoon and evening hours both
today and Thursday. There is a 40% chance of SCA level winds
developing again Friday afternoon evening. After a lull on
Saturday, there is a 50% chance of SCA level winds Sunday
afternoon and evening.

For the inner waters south of point conception, moderate to high
confidence in current forecast. High confidence in SCA level west
to northwest winds this afternoon through tonight. For Thursday
and Thursday night, moderate confidence (50% chance) in SCA level
winds continuing. After a lull on Friday and Saturday, there is a
40% chance of SCA level winds across western sections on Sunday.

For all waters, there is a slight chance of thunderstorms Thursday
and Thursday evening.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
