Synopsis 22 803 pm.

Low pressure continues to bring additional clouds, cooler
temperatures and a slight chance of showers across the region
Thursday. Dry weather is expected Friday, and we may see a few
showers the mountains Saturday. Another chance for rain moves in
Sunday into Monday morning.

Short term (wed-sat) 22 804 pm.

***update***
a good sized lobe of PVA rotated through la and vta county from
the north to the south. It intersected with an atmosphere that had
been destabilized by the cold air aloft associated with a passing
upper level trof. These two items combined to form a convective
burst that lasted for about three hours. Numerous tstms were
spawned. Many of the tstms produced hail some as large as three
quarters of an inch. Late in the afternoon the cold air aloft
departed and NVA followed on the heals of the pva. These two items
brought a swift end to the shower activity and skies cleared out.

Forecast problem for the night is the formation of low clouds.

All forecast mdls indicate a large amount of stratus forming
tonight and that is the official forecast but there is a
significant chc that it will not form or form to a much lesser
degree.

Another much weaker lobe of PVA moves through the area tomorrow
morning after dawn. Due to the NW flow pattern this will likely
bring showers first to the central coast then the north slopes
near the kern county line and finally it will wrap into the san
gabriel valley. The NW downsloping flow will very likely prevent
showers from affecting southern vta and sba counties as well as
sw la county.

Forecast is in good shape and no update is needed.

***from previous discussion***
another impulse is expected to come through Thursday with the
best chances for showers over the mountains as we shift from a
northerly flow to a south and southwest flow. But light showers
are possible in the morning along the central coast and south of
pt conception as well. Temps will remain several degrees below
normal with plenty of clouds and possible showers.

Warmer and sunnier weather on tap for most areas Fri Sat in
between trough passages. Clouds will be on the increase from the
west Saturday as the next trough approaches. And there is a chance
of showers over the mountains, especially ventura county Saturday
afternoon.

Long term (sun-wed) 22 223 pm.

Confidence is growing that we will see some additional
precipitation late this weekend as another upper low drops south
along the west coast. It's taking an inside track so moisture is
an issue but most of the model solutions support at least some
light (under a tenth of an inch) precip over much of the area
Sunday.

The upper low is expected to lift northeast Sunday night with
decreasing clouds and shower chances. At this point Monday-
Wednesday looks dry and warmer with a weak ridge developing over
california. The ECMWF isn't quite as robust with the ridging but
all models are dry and at least slightly warmer through the
period.

Aviation 23 0050z.

At 2320z at klax, there was no marine layer nor a sfc based
inversion.

Low confidence in non desert tafs. There is a 40 percent chc that
low clouds will not form overnight. If low clouds do form there is
low confidence in timing and cig hgts. If low clouds do form there
is a 30 percent chc that there will be sct conds after 20z.

Klax... Low confidence in taf. There is a 40 percent chc that low
clouds will not form overnight. If low clouds do form there is low
confidence in timing and cig hgts. If low clouds do form there is
a 30 percent chc that there will be sct conds after 20z. There is
a 30 percent chc of an 9 kt east wind component 10z-16z.

Kbur... Low confidence in taf. There is a 40 percent chc that low
clouds will not form overnight. If low clouds do form there is low
confidence in timing and cig hgts. If low clouds do form there is
a 30 percent chc that there will be sct conds after 20z.

Marine 22 819 pm.

For the outer waters, high confidence in current forecast. Winds
and seas are expected to drop below small craft advisory (sca)
levels during mid morning thu. There is a 20% chance that sca
conds will persist into the early afternoon hours. For Fri thru
sun, winds and seas will remain below SCA levels. SCA level winds
are likely Mon across the northern zone, with a 40-50% chance of
sca level conds across the remainder of the outer waters.

For the inner waters north of pt sal, high confidence in current
forecast. Winds and seas are expected to drop below SCA levels
late tonight. Then, SCA level conds are not expected Thu thru sun,
sca level winds are likely mon.

For the inner waters south of pt conception, winds and seas are
expected to drop below SCA levels late tonight. Then, SCA level
conds are not expected Thu thru sun, there is a 40% chance of sca
level winds Mon across sba channel, mainly western portions.

Beaches 22 1145 am.

Another large northwest swell will move through the coastal
waters today. High surf is expected along west and northwest
facing beaches across the central coast and a high surf advisory
remains in effect through tonight.

South of point conception, a recent observation in ventura county
has exceeded high surf advisory criteria, so there may soon be an
update to include higher forecast breakers and a high surf
advisory for ventura county. A beach hazards statement remains in
effect for the beaches of los angeles county through tonight.

Lox watches warnings advisories
Ca... High surf advisory in effect until 5 am pdt Thursday for

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.
