Synopsis 22 106 am.

Scattered showers are expected through warly this morning. Dry
weather will prevail through the weekend and into early next week.

There is a slight chance of showers across north of point
conception Friday and Friday night. Cool temperatures through
Friday, but will warm up by going into the weekend.

Short term (tdy-sat) 22 310 am.

The cold front is moving through la county and will be out of the
county in an hour or two. The cold front moved fairly slowly
through slo and sba counties but then really picked up speed as
the strong jet interacted with it and really sped it up. The
front brought about 4 hours of moderate to locally heavy rain to
all of the area from the beaches to the coastal slopes. These
areas generally received a quarter to three quarters of an inch of
rain. There were two notable exceptions. The coastal slopes north
of the city of san luis obispo saw 1 to 2 inches of rain. The sba
south coast received a half inch to an inch. The interior
sections pretty much only saw light rain with totals mostly
between a quarter and a half inch of rain.

Only scattered showers will remain behind the front and there will
be little additional rainfall amounts.

The moist ground left in the wake of the front has spawned some
low clouds and patchy dense fog. The clouds will slowly clear this
morning and there will be partly cloudy skies in afternoon. Max
temps will be in the upper 60s for the most part or about 3
degrees blo normal. There will be some gusty west winds across the
antelope vly this afternoon.

The winds will shift to a northerly direction tonight. There will
be a sundowner across the sba south coast as well as a down
through the i-5 corridor. The winds will come in just below
advisory criteria. Away from the winds the long night and clear
skies will allow the ground moisture to form areas of low clouds
and patchy dense fog across the coasts.

Moist NW flow will set up over the area on Friday. A couple of
weak impulses will ripple through the flow and will bring a slight
chc of rain to slo and sba counties as well as the north slopes of
the vta mtns. Rainfall amounts will be very light probably a trace
to .05 of an inch. Skies will be mostly cloudy up north but
likely just partly cloudy for vta and la counties. The extra
sunshine and north flow will bring some warming to vta and la
counties while the central coast will see little change.

A few more weak impulses with a slight chc of rain are slated to
move through slo county, portions of sba county and the north
slopes. Once again the rainfall amounts will be the very light
side. Stronger N flow sets up across la county Friday night and
there will likely be wind advisories across the la mtns and the
antelope vly.

Dryer flow will set up after dawn on Saturday. The north flow will
ride up the north slopes and generate clouds and a slight chc of
showers there. Aside from the north slopes skies will be mostly
sunny or at worst partly cloudy. MAX temps will not change much
from Friday and will be near normal or maybe a degree under.

Long term (sun-wed) 22 254 am.

The ec and the GFS are in decent agreement through the days 4
through 7 period.

Both show an east pac ridge nosing into ca from the SW on Sunday
and then strengthening on Monday. At the same time a strong and
cold dome of high pressure builds into the great basin setting up
decent offshore flow. Current mdls show offshore grads running
about 3 mb both from the north and the east. There is ok cold air
advection on Sunday and this might be enough to bring a low end
advisory to the usual santa ana wind prone locations. The cold
air advection will cool the interior while the compressional
heating will warming the air enough to bring a few more degrees of
warming.

Monday there will be similar sfc grads but less upper support.

This should keep the winds below advisory thresholds. With less
cool air advection MAX temps will rise everywhere.

A pac NW trof will knock the ridge down on Tuesday. The offshore
flow will weaken as well. It will be a pleasant day with only
light morning canyon winds and mostly clear skies. MAX temps will
be a degree or two cooler than Monday (esp at the coast) but max
temps will still be running 3 to 5 degrees above normal.

Mdls disagree a little on Wednesday. The GFS develops a very weak
ridge which keeps a weak trof pushed to the north. The ec has a
little more zonal flow which allows for the trof and a little rain to
approach the central coast. For now favoring the drier GFS soln.

Both mdls do agree that another wet pattern will set up from next
Thursday into next weekend.

Aviation 22 1034z.

At 08z, there was no marine layer at klax.

Low-to-moderate confidence in the current forecast. Periods of
MVFR conditions will continue at regional terminals through 18z as
a frontal system continues to move over the area. There is a
chance of lifr to ifr conditions in heavier rain showers.VFR
conditions should develop between 15z and 19z. There is a chance
of moderate wind shear and turbulence at ksba after 01z.

Klax... MVFR conditions will likely linger through at least 11z or
as late as 16z. There is a 30 percent chance that ifr conditions
could linger until 13z. There is a 60 percent chance of ceilings
at or below 5000 feet lingering until 19z or 20z. East winds
between 5 and 10 knots are possible through 12z.

Kbur... MVFR conditions will likely linger through at least 12z or
as late as 17z. There is a 30 percent chance that ifr conditions
could linger until 13z. There is a 70 percent chance of ceilings
at or below 5000 feet lingering until 19z or 20z.

Marine 22 225 am.

A storm system will continue move through the waters this morning.

A slight chance of thunderstorms are possible through 6 am pst,
mainly for the waters adjacent to the central coast.

Otherwise, gusty west to northwest winds and short-period choppy
seas will develop later today, mainly south and east of point
conception and into the southern california bight. A long
duration of small craft advisory conditions is likely through the
weekend with building gusty west to northwest winds and short
period seas, including the santa barbara channel and santa monica
basin.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect from noon today to 6 am pst
Friday for zones 650-655-673-676. (see laxmwwlox).
