Synopsis 22 258 pm.

Gusty offshore winds will continue through Wednesday across many
mountain and valley areas and will be strongest during the morning
hours. Temperatures will gradually warm through the week to above
normal as conditions remain dry and sunny.

Short term (tue-fri) 22 758 pm.

The latest satellite imagery shows a blocking ridge of high
pressure centered near 30n and 125w, while a trough digs into the
borderland region of new mexico and west texas. The ridge will
continue to build over the eastern pacific ocean through
Wednesday, keeping the polar jet, or jetstream far north of the
area. A warming and drying trend will continue into late this week
as an offshore flow regime remains in place. Gusty santa ana
winds will subside some tonight and Wednesday, before
restrengthening again between Thursday and Friday. A wind advisory
remains in effect for much of los angeles and ventura counties
through noon Wednesday.

In wind-sheltered areas, some cold nights are on tap for portions
of this week, including the central coast, the santa ynez and ojai
valleys, and the interior portions of the area. The coldest
temperatures will be in the antelope valley, where temperatures will
dip into the 20s later tonight and into early Wednesday morning.

As most areas have had several hard freezes already, a frost
advisory is only being considered for the ojai valley for late
tonight and early Wednesday morning.

***from previous discussion***
additional sub-advisory offshore winds will prevail night and
morning hours for many of these areas into thu, then another round
of advisory level winds can be expected Thu night into fri
morning as offshore gradients increase substantially (nam
predicted gradients for lax-dag at 12z Fri is -7.5 mb).

Mostly clear skies with a few hi clouds at times will prevail across
the forecast area tonight through fri. Temps are forecast to rebound
to near normal to slightly above normal for many areas on wed. It
will be warmer on Thu and Fri with above normal temps just about
everywhere thanks to offshore flow and warming at 850 mb and in the
boundary layer. Look for highs in the warmest vlys and inland
coastal areas to reach the upper 60s to mid 70s on wed, and
generally in the 70s on Thu and fri. Low temps will also be quite
cool again tonight with the coldest sheltered vlys dropping to near
or slightly above freezing, especially over slo sba counties. It
looks like widespread frost is likely for the slo county interior
vlys, with freezing conditions in the mid to upper 20s expected for
the antelope vly.

Long term (sat-tue) 22 159 pm.

The ec and GFS are in generally good agreement with the synoptic
features over the ERN pac to western u.S. For Sat thru tue. The
upper level ridging along and off the ca coast will build and
expand into ca over the weekend, with 500 mb heights reaching to
586 dm or so by early sun. The upper level ridge will then slowly
weaken Mon and Tue while moving back to or just off the ca coast.

Dry weather with mostly offshore flow will prevail across the
forecast area thru the extended period.

Gusty offshore winds night and morning hours can be expected across
swrn ca sat, with gusts possibly reaching advisory levels in the
wind-prone areas. Sub-advisory offshore flow can be expected into
sun, with a transition to some weak onshore flow on mon. Offshore
gradients should increase quickly Mon night into Tue morning, with
support for possible advisory-level or even stronger northeast winds
during that time especially over portions of vtu l.A. Counties.

Mostly clear skies will continue across the region Sat thru sun,
then some mid and hi level clouds should move in for Mon with
partly cloudy skies as a whole. Mostly clear skies can then be
expected across the area for tue.

Temps are forecast to be several degrees above normal for many areas
sat thru sun. Temps for Mon should drop to slightly above normal for
the most part, then to near to slightly above normal for tue. Highs
in the warmest vlys and inland coastal areas should reach the mid
70s to near 80 on sat, 70s on sun, and upper 60s to lower 70s mon
and tue.

Aviation 22 2349z.

At 00z, there was no marine layer at klax.

Vfr conditions are expected through the period. There is a chance
of moderate low-level wind shear and turbulence at terminals
south of point conception through 16z.

Klax...VFR conditions are expected through the period. There is a
30 percent chance of moderate low-level wind shear and turbulence
between 04z and 08z. Any east winds should remain below 7 knots.

Kbur...VFR conditions are expected through the period. There is a
30 percent chance of moderate low-level wind shear and turbulence
between 04z and 10z.

Marine 22 809 pm.

For the outer waters, moderate-to-high confidence in current
forecast. Winds and seas will likely remain below small craft
advisory levels through Saturday. There is a 30 percent chance of
small craft advisory level winds on Wednesday evening, especially
near points conception and arguello.

For the inner waters north of point sal, moderate-to-high
confidence in current forecast. Winds and seas are expected to
remain below SCA levels through Saturday. There is a 20 percent
chance of small craft advisory level north to northeast winds
developing Wednesday night.

For the inner waters south of point conception, moderate
confidence in current forecast. There is a 70 percent chance of
small craft advisory level northeast winds again late tonight and
early Wednesday. Otherwise, winds and seas are expected to remain
below SCA levels through Friday. On Saturday, there is a 50
percent chance of small craft advisory level northeast winds
developing again, from ventura southward.

Lox watches warnings advisories
Ca... Wind advisory in effect until noon pst Wednesday for zones
41-44>46-53-54-88-547. (see laxnpwlox).

Pz... None.

Hazard potential outlook (fri-tue)

and morning hours Fri and Sat for wind-prone areas of ventura and
los angeles counties. These areas may have advisory-level to
possible high wind warning level wind gusts Mon night into tue.

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