Synopsis 23 811 pm.

Skies will be partly to mostly cloudy tonight with a few sprinkles
possible during the evening. Sunshine is expected on Sunday and
Monday with warming temperatures. Tuesday will bring increasing
clouds and cooler temperatures with a chance of rain north of
point conception. There is a chance of rain for all areas on
Wednesday.

Short term (sat-tue) 23 804 pm.

A weak upper-level trough continues to exit the state this
evening with the trough center now located near the northern
california-nevada border. A dying cold front is becoming very
disorganized as it pushes south over los angeles county this
evening. An outside chance exists for some showers this evening,
but mostly dry conditions with partly to mostly cloudy skies
should prevail.

A northerly surface pressure gradient is developing across the
region this evening. A marginal wind advisory was added earlier
for southern santa barbara county through 3 am pdt. Gusts up to
between 35 and 45 mph are possible and the strongest winds should
occur west of goleta toward gaviota. Another wind advisory is
being mulled over for the interstate 5 corridor for late tonight
and early Sunday morning, again a marginal case where winds might
hit criteria.

Otherwise, an upper-level ridge developing along the california
coast will build into the region through Sunday. A warming and
drying trend will develop into Monday.

***from previous discussion***
clouds should increase from NW to SE over the forecast area mon
night and tue. With a weak front draped over northern parts of the
region, a chance of showers will cover much of slo sba counties
during the period. Dry conditions are expected for vtu l.A.

Counties thru tue.

Temps on Sun with the offshore flow and increasing 1000-500 mb
thicknesses 850 mb temps boundary layer temps will be much warmer
and a few degrees above normal for many areas. This warming trend
should continue Mon for vtu l.A. Counties, while temps remain
largely unchanged over slo sba counties. Cooler conditions are
expected for most areas on tue. Highs in the warmest vlys and
coastal areas should reach the low to mid 70s on sun, 70s on mon
especially for l.A. Vtu counties, and upper 60s to low 70s on tue.

Long term (wed-sat) 23 202 pm.

The extended models bring the E pac upper trof and surface front
slowly inland Tue night and wed, with the ec a bit wetter than the
gfs. This system will continue moving E thru Thu with showers
possible Wed night and diminishing on thu. The ec continues to be
wetter during this period as well. Decided to lean slightly toward
the wetter ec solution with low to moderate confidence. Potential
rainfall with the mid-week system is for 0.25 to 0.50 inch for
slo sba counties, with up to 0.25 inch over vtu l.A. Counties.

The GFS forecasts an upper low will form over the far NRN ca coast
thu night then push inland and SE thru eastern ca western nv as an
inside slider Fri thru sat. However, the ec builds an upper level
ridge along the ca coast Fri with the ridge moving into the state on
sat. Altho both solutions would bring dry weather to the forecast
area Fri and sat, the GFS forecast would result in cooler and breezy
to windy conditions while the ec forecast would result in
significantly warmer conditions to the area especially by sat. A
model blend with low to moderate confidence was made for this period.

Overall it looks like temps will be cooler than normal Wed and thu,
near normal fri, and near normal to slightly above normal sat.

Aviation 24 0543z.

At 05z, there was no marine layer or inversion at klax.

Expect patchy to areal low cloud coverage with mostly MVFR conds
in coastal and valley areas overnight through mid to late morning
Sunday, thenVFR conds are expected. There will be local lifr to
vlifr conds in the mtns through mid morning sun, and possibly in
the interior valleys of slo county late tonight early sun
klax... Low to moderate confidence in the 06z taf. There is a
30-40% chance that conds will remainVFR overnight Sun morning.

Kbur... Low to moderate confidence in the 06z taf. There is a
30-40% chance that conds will remainVFR overnight Sun morning.

Marine 23 907 pm.

For the outer waters, moderate confidence in current forecast.

Small craft advisory (sca) conditions due to a mix of seas and
winds will continue through Sunday morning. For Monday and Monday
night, there is a 40 percent chance of SCA level southerly winds
across pzz670 673. On Thursday, there is a 60 percent chance of
sca level west to northwest winds across all the outer waters.

For the inner waters north of point sal, high confidence in
current forecast. SCA conditions, primarily due to seas will
continue through Sunday morning. For Wednesday and Thursday,
there is a 60 percent chance of SCA level west to northwest winds
during the afternoon and evening hours.

For the inner waters south of point conception, moderate
confidence in current forecast. A SCA was extended until 3 am
Sunday morning. There is a 30 percent chance of SCA level winds
across pzz655. For Sunday through Tuesday, winds and seas are
expected to remain below SCA levels. On Wednesday and Thursday,
there is a 50 percent chance of SCA level westerly winds
developing.

Beaches 23 911 pm.

A moderate period west to northwest swell will continue to
generate high surf on the central coast between 10 and 14 feet.

Surf will also build along the west facing beaches south of point
conception, especially along the ventura county coast where waves
should peak in the 5 to 8 feet range. There is a chance that some
spots on the los angeles county coast will also see waves of 7
feet. As a result, a high surf advisory is in effect for these
areas. The exposed west facing beaches of santa barbara county,
like rincon, could also see waves near 7 feet, but surf will be
localized and should not need an advisory. The swell and surf
should gradually subside on Sunday.

Waves like this pose a serious risk to anyone that enters the
ocean. Strong and deadly rip currents will be happening. Please
emphasize the special risk of anyone on the rock jetties, as there
is a long history of fatalities from people that go on the rocks
and tide pools during such events.

Lox watches warnings advisories
Ca... High surf advisory in effect until 9 pm pdt Sunday for zones
34-35-40-41-87. (see laxcfwlox).

Small craft advisory in effect until 9 am pdt Sunday for
zones 673-676. (see laxmwwlox).

Hazard potential outlook (tue-sat)
A storm system could bring rain and snow above 6000 feet to the
region between Tuesday and Wednesday. Gusty winds are possible
with this storm, especially in the mountains. High surf is
possible late Wednesday.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
