.SYNOPSIS...18/213 AM.

Skies will slowly clear today and a warming trend will start.
Even warmer temperatures are expected Saturday through the middle
of next week, but still 3 to 6 degrees below normal across the
coast and valleys.

&&

.SHORT TERM (TDY-SUN)...18/257 AM.

A deep 6000+ foot moist layer is slowly transitioning into a more
traditional marine layer as an inversion is starting to form
around 3000 ft. Most areas across the forecast area are mostly
cloudy esp SLO county, western SBA county and the mtns. Partly to
mostly cloudy conditions cover the rest of area save for the
Antelope Vly which is clear. There is enough residual moisture
that clouds might disipate early but then reform in the afternoon
due to sfc heating. The only chance of rain today will be over the
eastern San Gabriels where there is just enough instability and
moisture to warrent a slight chc of a shower. Hgts will rise
today as ysy`d trof pushes to the east. This and enough breaks in
the clouds to allow for some sunshine will lead to 4 to 8 degrees
of warming for most of the area. Even with this warming most areas
will end up 3 to 6 degrees blo normal. The LA/VTA vlys and mtns as
well as the Antelope Vly, however, will come in 6 to 12 degrees
blo normal.

Look for a big warm up Saturday as a weak ridge slides into and
over the state. Hgts rise to 576 dam. Skies will be sunny save for
some morning low clouds. SLO and SBA counties as well as the LA
and VTA csts will see 2 to 4 degrees of warming will the rest of
LA/VTA county will end up 5 to 10 degrees warmer than today.
Still. most max temps will come in a few degrees cooler than
normal.

Sunday will continue the warming trend. Onshore gradients will be
on the weaker side and marine layer stratus will be confined to
the Central Coast in the morning. Bountiful sunshine and a weaker
seabreeze will bring 2 to 4 degrees of warming to most of the
area. The csts and lower vlys will remain a few degrees blo normal
but the rest of the area will be above normal for the first time
in a while.

.LONG TERM (MON-THU)...18/309 AM.

The GFS and the EC as well as their respective ensembles are in
decent agreement and show the west coast under broad troffing
through the period. Hgts will slowly fall from 576 dam on Monday
to 572 dam on Thursday. There will be onshore flow through the
period, strongest in the afternoon when it will be moderate to
strong. Night through morning low clouds and fog will occur each
day across most of the coasts and with the strong onshore push
into many of the vlys as well. The SBA south coast will have some
local north winds and may stay clear. Skies, otherwise, will be
mostly clear through Wednesday, but will turn partly cloudy on
Thursday as some mid level clouds will move over the state.

Max temps will be similar to Sunday`s on Monday but then the
entire area will see cooling all three days Tue-Thu as hgts fall
and onshore flow increases. By Thursday most max temps will be in
the 60s across the csts and vlys or 4 to 8 degrees blo normal.

.AVIATION...18/0953Z.

At 0945Z at KLAX, there was a 7500 ft deep moist layer.

Overall, low to moderate confidence in 12Z coastal/valley TAFs and
high confidence in desert TAFs. For coastal/valley sites, CIGS
will vary between MVFR and VFR levels through 20Z, then turn SCT-
BKN040-060 20Z-02Z. After 02Z, there is a 50-70% chance of MVFR
CIGs returning to coastal/valley sites.

KLAX...Overall, moderate confidence in 12Z TAF. There is a 50%
chance of MVFR CIGs 12Z-18Z. For tonight, moderate confidence in
return of MVFR CIGs, but low confidence in timing (could be +/- 4
hours of current 08Z forecast). No significant easterly wind
component is expected.

KBUR...Overall, moderate confidence in 12Z TAF. Current MVFR CIGs
could improve to VFR levels as early as 15Z. Timing of CIG
dissipation this afternoon could be +/- 2 hours of current 20Z
forecast. For tonight, there is a 30% chance of MVFR CIGs
returning after 08Z.

&&

.MARINE...18/253 AM.

For the Outer Waters, moderate to high confidence in current
forecast. Today through Monday, there is a 20-30% chance of Small
Craft Advisory (SCA) level northwest wind gusts around Point
Conception down to the Northern Channel Islands with winds and
seas expected to remain below SCA levels elsewhere. On Tuesday,
there is a 60-80% chance of SCA level winds.

For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast. Today through Monday, high
confidence in winds and seas remaining below SCA levels. On
Tuesday, there is a 30-40% chance of SCA level winds in the
afternoon and evening hours.

For the Inner Waters south of Point Conception, high confidence in
current forecast. Today through Tuesday, high confidence in winds
and seas remaining below SCA levels across most areas. The only
exception will be the western half of the Santa Barbara Channel
where there will be a 20-30% chance of SCA level winds Saturday
and Sunday during the evening and overnight hours.
