Synopsis 13 811 am.

High pressure will bring breezy offshore winds and above normal
temperatures to the area today. A weak frontal system is expected
to bring mostly cloudy skies and cooler temperatures on Friday.

A second frontal system may bring a chance of rain Sunday night
into Monday.

Short term (tdy-sat) 13 949 am.

Offshore gradients slightly weaker than the NAM had predicted
yesterday and absent any upper support winds this morning are well
below advisory levels. Will probably see an increase in winds
later this morning but mostly in the 15-25 mph range. Still
expecting a generous warm up today as there's good low level
subsidence in place and a strong upper ridge building over the
west coast. The lax profiler is showing 24 hour temperature
increases ranging from 5-8 degrees below 1500' so the forecast
temps today look on track.

***from previous discussion***
on Friday the ridge weakens and the offshore grads relax. Clouds
will increase through the day as mid and high level clouds stream
out in front of an east pac trof. The central coast will see the
most clouds. There will be 3 to 6 degrees of cooling across the
csts vlys and 1 or 2 degrees of cooling across the interior. These
max temps will still be a few degrees above normal.

The tail end of a weakening cold front will move through Friday
night. Last nights mdls were all dry but then came in wetter for
the 12z through 00z runs. The 06z runs have now switched back to
dry. Way too much variability to pull the pops again and will
continue with the earlier thinking with a slight chc of rain for
coastal slo county. Fast moving zonal flow will quickly replace
the trof on Saturday. Skies will clear out and there will be a few
degrees of warming.

Long term (sun-wed) 13 323 am.

On Sunday the flow will turn to the southwest and hgts will start
to fall as a trof approaches the state from the west. Clouds will
increase as well as mid and high level clouds ahead of the system
begin to move into the area. MAX temps will fall 2 to 4 degree
across the area.

The trof and the front draw closer Sunday night and skies will
turn mostly cloudy everywhere. Both the GFS and the ec agree that
the only chc of rain before midnight will be across the NW corner
of slo county. As the front draws nearer rain will become likely
across the central coast. The clouds, rain, 560 dm hgts and a very
short day will keep most of the temps across the csts and vlys
near 60.

The front will be strong enough to bring rain to the almost all of
the 4 county forecast area during the day Monday before turning to
showers. The GFS continues to be the most bullish mdl but the ec
is not as far behind as it used to be. Right now this looks likes
a quarter inch to half inch sort of systems that will not produce
dangerous rainfall rates.

Monday night and early Tuesday will see a quick transition to
clear skies and offshore flow as a ridge builds into the area. Max
temps will see a huge 5 to 10 degree rebound Tuesday. The ridge
and the offshore flow continues to build on Wednesday and max
temps will see another 4 to 8 degree bump up which will put them
well above normal.

Aviation 13 1820z.

At 1724z, at klax, the marine layer depth was 500 feet. The top
of the inversion was at 900 feet with a temperature near 19
degrees celsius.

High confidence with 18z tafs.VFR conds are expected over the
next 24-hour period.

Klax... High confidence with 18z taf. ExpectVFR conditions
throughout the 30-hour period.

Kbur... High confidence in 18z taf.VFR conditions are expected
throughout the period.

Marine 13 915 am.

Moderate-to-high confidence in the current forecast. A moderately large
northwest swell will gradually build into the coastal waters
today and persist through Saturday night. This swell will
diminish some on Sunday, with hazardous seas developing across
outer and northern coastal waters today through Saturday night.

Between Sunday night and Tuesday, a very large swell is expected
to build into the coastal waters and affect west to northwest
facing harbors, including morro bay. Ventura harbor could also be
affected on Monday through at least Tuesday as some of the energy
from the swell filters into the socal bight.

Beaches 13 952 am.

An extended period of high surf continues to be likely at central
coast beaches through Monday. There is a 50 percent chance of
very large and potentially damaging surf developing over the
upcoming weekend and into early next week. The latest swell models
build a west-northwest swell to between 18-22 feet off the
central california coast with periods between 19 and 20 seconds.

Swell energy could possibly push into southern california bight
between Sunday and Monday.

If swells develop inline with model guidance, surf of 15-20 feet
with sets up to 25 feet will be possible at west and northwest
facing beaches along the central coast between Sunday night and
Tuesday. South of point conception, west facing shores could
potentially see surf between 8-12 feet.

Lox watches warnings advisories
Ca... High surf advisory in effect until 8 pm pst Saturday for
zones 34-35. (see laxcfwlox).

Pz... Small craft advisory for hazardous seas in effect until 9 am
pst Friday for zones 645-670-673-676. (see laxmwwlox).

Hazard potential outlook (sat-wed)
Very high surf and dangerous rip currents are expected Monday and
Tuesday.

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.
