Synopsis 20 1025 pm.

There is a chance of snow showers in the ventura and los angeles
county mountains through Monday evening. Otherwise conditions will
be dry across the region this week. Winds will be breezy then gusty
santa ana winds will develop Tuesday morning. Temperatures will be
cool on Monday then there will be a warming trend during the week.

Short term (tdy-wed) 21 303 am.

Yesterdays weak cold front has passed on by. It dropped light
amounts of rain across slo and NRN sba counties. Strong northwest
winds have developed in the wake of the front and the upslope flow
near the kern county line will bring clouds and a chance of light
rain snow showers across the north facing mountain slopes for the
rest of the day and into the evening. Light rain showers are also
possible across the san gabriel foothills this morning due to
favorable cyclonic flow.

Snow levels will were above 6000 feet yesterday but with all the
cold air pushing in they will lower rapidly this morning,
especially near the kern county line. Snow levels will dip to
3500 feet today. This low a snow level will bring snow showers
to interstate 5 near the grapevine as well as highway 33 in the
ventura county mountains. Total snow accumulations with this
system will be between 1-3 inches across north facing mountain
slopes. The grapevine could see almost an inch of snow. The snow
showers will combine with the strong post frontal winds will
produce difficult driving conditions. A winter weather advisory
continues for the north facing mountains of la ventura counties
(including interstate 5) through noon.

The post frontal winds fueled by a strong sfc pressure gradient,
cold air advection and good upper support will bring northwest to
north advisory level winds to much of the area. The strongest
winds are expected in the mountains (especially i-5 corridor,
santa ynez range, and hwy 33 corridor in ventura county). The antelope
valley will also be very windy today with gusts between 45 and 55
mph will be common along with isolated gusts to 60 mph in favored
locations. Strong winds will also occur across the sba south
coast, with gusts over 50 mph in the hills.

All of the cold air advection will make today the coolest day of
the next 7 with MAX temps coming in 3 to 6 degrees below normals.

Strong cold sfc high pressure builds into nv on Tuesday and will
set up a strong NE offshore pressure pattern. The winds will
shift to the northeast early Tuesday and a santa ana wind event
will start up. The strongest winds will set up in the la county
mountains and will extend to the SW going through the santa
clarita vly, the western san fernando vly, the eastern portion of
the ventura vlys. The winds will also flow through the santa
monica mtns and will squirt out and over the beaches from malibu
to pt mugu.

There will be a little warming on Tuesday across the coasts and
vlys (the interior will see temps similar to today) due to the
compressional warming of the offshore winds. But since there will
also be quite a bit of cool desert air arriving with the santa ana
winds there will only be 2 to 4 degree of warming and most areas
max temperatures will remain below normal.

The santa ana winds will continue Wednesday but there will be much
less upper level and thermal support. The windiest mtn and vly
locations will see low end advisory gusts. By noon, however, the
diurnal pressure trends will diminish the winds to below the
advisory thresholds.

With less cold air advection there will be a good jump in temps
everywhere and most if not all areas should see MAX temps rise to
3 to 6 degrees above normal under sunny skies.

Long term (thu-sun) 21 309 am.

Both the ec and GFS agree that the state will be under the
eastern half of an east pac high for the entire time thu-sun. Sfc
high pressure remains anchored over the great basin through the
period and there will be varying degrees of offshore flow through
the period. Right now it looks like Friday will have the strongest
offshore flow and some low end advisories may be needed then.

The ridge and the offshore flow should keep skies mostly clear
through the period. The higher than normal hgts combined with the
offshore flow will bring well above normal temps to the area for
all four days. Currently Saturday is slated to be the warmest of
the next 7 with mx temps 8 to 12 degrees above normal.

Aviation 21 1030z.

At 1030z, there was no marine inversion at klax.

Overall, moderate to high confidence in 12z TAF package. High
confidence inVFR sky conditions for all sites through the taf
period with sct-bkn040-060 deck possible through 20z. Moderate
confidence in wind forecast due to some uncertainty of the timing
of changes in strength direction. There is 40% chance of some MVFR
vsbys in blowing dust sand at kwjf kpmd 16z-02z.

Klax... Moderate confidence in 12z taf. High confidence inVFR
conditions through TAF period. Moderate confidence in timing of
changes in wind strength direction. There is a 50% chance of
northerly cross winds around 15 knots 03z-12z.

Kbur... Moderate confidence in 12z taf. High confidence inVFR
conditions through TAF period. Moderate confidence in timing of
changes in wind strength direction.

Marine 21 230 am.

For the outer waters, moderate confidence in current forecast.

Strong small craft advisory (sca) level northwest winds will
continue through tonight with a 20% chance of gale force gusts. On
Tuesday, there is a 30% chance of SCA level winds then winds and
seas are expected to remain below SCA levels Wednesday through
Friday.

For the inner waters north of point sal, high confidence in
current forecast. SCA level northwest winds will continue through
tonight. For Tuesday through Friday, winds and seas are expected
to remain below SCA levels.

For the inner waters south of point conception, moderate
confidence in current forecast. High confidence in SCA level west
to northwest winds through this evening. For Tuesday and
Wednesday, there is a 60% chance of SCA level northeast winds from
point mugu southward. For Thursday and Friday, winds and seas are
expected to remain below SCA levels.

Beaches 21 230 am.

A new west to northwest swell will move into the coastal waters
today. These swells will produce elevated surf and strong rip
currents on west-facing beaches through Tuesday. Large
astronomical high tides are also be expected each morning through
this time, peaking today. Due to the higher than normal tides and
elevated surf, there could be minor coastal flooding near the
times of the morning high tide each day. As a result of the
elevated surf and potential for minor coastal flooding, a beach
hazards statement is in effect for all west facing beaches through
Tuesday.

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