Synopsis 18 258 pm.

Gusty north to northwest winds are expected to continue tonight
through Sunday, with the strongest winds expected Saturday night.

Weak santa ana winds are expected Sunday night through Tuesday
with temperatures warming above normal.

Short term (tdy-mon) 18 146 pm.

Wind continues to be the primary weather concern over the next few
days. We had isolated warning level wind gusts early this morning
in the i5 corridor and in SRN sb county. The parameters aren't
quite as favorable tonight as upper support is weaker due to the
trough having moved to the east. Still pretty impressive surface
gradients though and enough to keep wind advisories going for srn
sb county and the i5 corridor.

Pretty similar day Saturday as today overall with temps within a
few degrees of today. We'll be transitioning to another strong
northerly wind event later Saturday into Sunday so we'll likely
see winds increasing in strength in many areas by afternoon and
evening. Then overnight into Sunday the upper support from the
trough passage will kick in along with some cold air advection to
push wind speeds up to at least Thursday night's levels and likely
a tad stronger. Models still showing a 6-7mb gradient from bfl
early Sunday morning which is 1-2mb stronger than what happened
earlier this morning. For this reason a high wind watch will be
issued for all the mountains, including the santa monicas, as well
as the santa clarita valley Saturday night into Sunday morning.

Advisory level winds expected to develop in many other areas
including the la ventura valleys and even parts of the la coast,
especially from malibu to the hollywood hills and down through the
south bay area. Highs Sunday expected to rise 3-6 degrees in most
areas.

Sunday afternoon into Monday we'll be transitioning to a low
grade santa ana as the trough moves east and winds take on a more
easterly component. Upper support drops off and the air mass warms
as the ridge starts building in from the west but there will be
just enough surface gradient and winds up to 850 mb to maintain
gusty (though mostly sub-advisory level) santa ana winds across
la ventura counties as well as the santa lucia's along the central
coast. Temps will be warming up quite a bit as well with highs
jumping up into the lower 90s for inland coastal areas and
valleys.

Long term (tue-fri) 18 143 pm.

Tuesday is expected to be the warmest day for coast valleys as
gradients will start trending onshore later in the day into
Wednesday. Some light offshore breezes possible, mainly in the
mountains, but otherwise just hot and dry.

The ridge will start to shift back to the west as a trough drops
out of canada and into the northern rockies and great basin.

Gradients will turn onshore Wednesday into Thursday with high
temps dropping several degrees across coast valleys, though still
a few degrees above normal. The pacific ridge is expected to
expand east again over california and gradients will again turn
offshore following the trough passage through the great basin and
into the plains. The GFS has fluctuated a fair amount on this but
the ECMWF has been consistent and now more ensemble members are
supporting at least an advisory level santa ana wind event Friday
into next weekend and likely very warm and dry.

Aviation 18 1742z.

At 17z at klax, there was no marine inversion. There was a
shallow moist layer around 1500 feet deep.

Vfr conditions with clear skies expected across the majority of
terminals. The only exception will be scattered MVFR clouds across
the la basin after 09z Saturday and could impact klgb or klax by
sunrise. Gusty N to NW winds will affect the mountains, the santa
clarita valley and the south coast of sba county through Saturday,
with associated local llws and moderate uddf.

Klax... High confidence in the 18z taf.VFR conds expected through
the period. There is a 10% chance of MVFR CIGS between 12z and
17z Saturday morning. East winds will remain below 8 kts between
10-17z tomorrow.

Kbur... High confidence in the 18z TAF withVFR conds expected
through the period.

Marine 18 213 pm.

Outer waters... Moderate to high confidence. Gale force winds were
occurring across most of the outer waters, except for the far
north. Gales will decrease to small craft advisory levels later
tonight and then continue through about Sunday night. Winds turn
more northerly by Monday and even east-northeast for lighter winds
across outer waters.

Inner waters N of pt. Sal... Moderate to high confidence. Sca
level NW winds are likely through Sat evening and there is a
chance of SCA level NW winds Sun afternoon and evening.

Santa barbara channel... Moderate confidence. SCA level W to nw
winds are expected across western portions through late tonight.

Sca level W to NW winds are possible across western portions
again Sat afternoon and into the evening.

For the inner waters south of pt. Mugu... Moderate confidence.

Winds and seas are expected to remain below SCA levels through
tue. There is a 30% chance of SCA level N to NE winds near shore
from pt. Mugu to santa monica Sunday night and Monday morning.

Beaches 18 136 pm.

Surf will continue to build from 9 to 12 feet on west-facing
beaches of the central coast with local sets to 15 feet possible.

Surf will gradually subside early Saturday morning. There is a
chance that the surf will remain near or above the high surf
threshold of 10 feet through Saturday evening.

South of point conception, the northwesterly component of the
swell means that less energy will make it to shore. However, the
west facing beaches of ventura and los angeles counties could have
surf of 3 to 6 feet tonight through Sunday.

Fire weather 18 326 pm.

Northerly winds will persist across many portions of southwest california
through Sunday, with peak gusts between 30 and 50 mph common. These winds will
affect the mountains, santa barbara south coast, the santa clarita valley,
san fernando valley, santa monica mountains and central coast. The strongest
northerly winds will be over the santa ynez range and adjacent foothills, along
with the tejon pass Saturday night into Sunday, when isolated gusts of 60 to
70 mph are likely (especially near montecito hills and whitaker peak).

The santa barbara-bakersfield gradient is expected to peak at around -5.5 mb
later tonight, increasing to around -6.5 mb on Saturday night. Minimum
humidities will generally range between 8 and 25 percent today through
Sunday. Recoveries at night will be moderate across the north facing mountains
with poor recoveries in the foothills and downslope areas. The combination of
moderate to locally strong sundowner winds combined with low humidities and
dry fuels has resulted in the red flag warning for the santa barbara south
coast and mountains through Sunday evening. There will be widespread elevated
to brief critical fire weather conditions for many other portions of southwest
california through Sunday due to the northerly winds and areas of low humidities.

Areas closest to critical conditions include the los angeles and
ventura county mountains and santa clarita valley.

The winds are expected to shift to northeasterly Sunday night into Monday
when gusts between 25 and 40 mph will occur across wind prone areas of los angeles
and ventura counties, strongest in the los angeles county mountains. The offshore
winds will further weaken on Tuesday morning. Minimum humidities will generally
range between 10 and 20 percent on Monday and Tuesday, while high temperatures
will climb to between 85 and 95 degrees. Another warm and potentially very dry santa
ana wind event will be possible by next Friday.
