Synopsis 17 654 am.

Temperatures will be cooler this weekend then warmer next week
with the highest readings midweek. Overnight and morning low clouds
and fog will continue in coastal and adjacent valley areas through
Monday then will be primarily along the coast through Wednesday.

Short term (tdy-mon) 17 903 am.

The marine inversion this morning was near 2600 ft deep at lax. Low
clouds were quite widespread this morning, extending from the coast
well into the vlys and even into some lower coastal slopes. The low
clouds are forecast to clear back to the coast by midday with low
clouds probably lingering at some of the beaches thru the afternoon
thanks to good onshore gradients, which are expected to be around
+9.2 mb at 00z according to the latest nam. Otherwise, mostly sunny
skies will prevail across the region thru the afternoon.

The good onshore gradients will promote gusty S to W winds across
much of the foothills, mtns and deserts this afternoon. Temps will
be much cooler across the forecast area as well, with highs expected
to reach only into the 80s in the warmer vlys and lower mtns, altho
the antelope vly should still warm into the 90s this afternoon.

Temps overall across the region today will be 6-12 deg below normal
for this time of year.

An upper level trof will persist along and off the ca coast today
thru sun, with h5 heights in the 586-588 dm range. A large upper
level high over the southern plains will start to slowly expand w
and into SRN ca Sun night and mon, with h5 heights expected to
increase to 590-591 dm for Mon afternoon. A dry SW flow aloft will
prevail for the most part thru the period.

The marine inversion is expected to be slightly lower tonight into
sun morning, then shrink to about 1500-1800 ft or so Sun night into
mon morning. Even so, plenty of night and morning low clouds and fog
will affect the coastal areas into portions of the adjacent vlys
during the period. Low clouds and fog will likely affect the salinas
river vly for the late night and morning hours as well thru mon
morning. Otherwise, mostly clear skies will continue across swrn ca
thru mon.

The onshore flow will slowly decrease thru the period, with the lax-
dag forecast gradient (nam) expected to be about +8.3 mb sun
afternoon, and +7.3 mb Mon afternoon. Some gusty s-w afternoon and
evening winds will continue for the foothills, mtns and deserts each
day, with some gusty NW winds forecast for the central coast.

Temps are expected to remain about 6-12 deg below normal for many
areas on sun, then warm slightly to about 2-7 deg below normal for
mon. The warmest vlys and lower mtns should reach the 80s on sun,
and mid 80s to low 90s mon. The antelope vly should be in the 90s
each day.

Long term (tue-fri) 17 313 am.

By Tuesday the upper-level high will push further west and hgts
will rise to 594 dm over SRN ca. The onshore flow to the east
will be weak and offshore flow will develop from the north. This
will greatly reduce the marine layer stratus pattern and will
bring another 3 to 6 degrees of warming to all areas.

Similar to this week's warm up, Wednesday and Thursday will be the
warmest days and if the forecast remains valid there will be a
need for heat products. Hgts will remain near 594 dm, or about 5
dm higher than normal. Weak onshore flow to the east and 2 to 3 mb
offshore flow from the north is expected. There will be minimal
morning stratus. Temperatures will jump another 4 to 8 degrees and
will be above normal almost everywhere. The ridge will break down
a little on Thursday which will drop MAX temps by 2 to 4 degrees.

The ridge breaks down further next Friday and the onshore flow
begins to reassert itself. The marine layer and the attendant
marine layer stratus will begin to redevelop. MAX temps will fall
another 2 to 5 degrees.

Still tracking a tropical system forecast to develop around
southern baja california Friday and move to the north. The
moisture and swell from this system could affect SRN ca's weather
during the week of the 26th.

Aviation 17 1149z.

At 1117z at klax, the marine layer was around 2200 feet deep. The
top of the inversion was around 4500 feet with a temperature of
22 degrees celsius.

High confidence in 12z desert tafs and moderate confidence in
coastal and valley tafs.VFR transition could be delayed by up to
an hour.

N of point conception... Moderate confidence with lifr ifr cigs
including kprb. Scour out times should occur within an hour of 12z
tafs. Look for a similar stratus pattern once again this evening
into Sunday morning. Slightly higher confidence for only ifr and a
20% chance for MVFR CIGS after 14z Sun at a few TAF sites. There
is a 20% chance that CIGS could linger past 21z at ksmx today.

S of point conception... Moderate confidence with MVFR tafs through
this morning. There is a 20-30% chance that CIGS could linger at
klax through 20z. Moderate confidence for a return of MVFR cigs
later this evening into Sunday morning.

Klax... Moderate confidence in 12z taf. Clearing could occur as
late as 19z. There is a 30% chance of a 6 kt east wind component
between 10z and 15z. There is a 30% chance that MVFR CIGS could
redevelop as early as 23z this afternoon.

Kbur... Moderate confidence in 12z taf. Clearing could occur as
late as 18z. Moderate confidence for a return of ifr MVFR cigs
after 08z tonight into Sunday morning.

Marine 17 815 am.

For the outer waters, moderate to high confidence in current
forecast. There is high confidence in winds and seas remaining
below small craft advisory (sca) levels today through Sunday.

On Monday, there is a 50% chance of SCA level winds developing
(especially across the southern waters) then a 70% chance of sca
level winds Tuesday and Wednesday.

For the inner waters north of point sal, moderate to high
confidence in current forecast. There is high confidence that
winds and seas will remain below SCA levels today through Monday.

There is a 60% chance of SCA level winds during the afternoon and
evening hours of Tuesday and Wednesday.

For the inner waters south of point conception, moderate to high
confidence in current forecast. In general, there is high
confidence that winds and seas will remain below SCA levels
today through Wednesday. The only exception will be the western
half of the santa barbara channel where there is a 60% chance of
sca level winds during the late afternoon and evening hours Monday
through Wednesday.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (mon-fri)
Hot temperatures could lead to heat advisories for some inland
areas next Wednesday and possibly Thursday. Otherwise, no
significant hazards are expected through the period.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

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