Synopsis 22 1203 pm.

Skies will be partly to mostly cloudy today with a chance of
showers mainly across the interior and a slight chance of
thunderstorms. A cool, showery, and unsettled weather pattern
will continue through the week and into early next week as a broad
trough of low pressure remains over the region.

Short term (tdy-sat) 22 210 pm.

Isolated thunderstorms developing over la ventura counties this
afternoon as a cold upper trough moves south through the area.

Lots of reports of small hail and brief heavy rain. Showers and
thunderstorms expected to taper off later this afternoon and
early evening as the cold air shifts to the south and east and we
lose the daytime heating.

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 22 1806z.

At 1721z, there was no marine layer at klax. However, there was a
moist layer up to 8000 feet.

Low to moderate confidence in the 18z TAF package. Deep moist
layer and some instability should generate bkn-ovc skies for most
sites through early this evening. Generally, CIGS are expected to
remain atVFR levels, but there is a 30-40% chance of MVFR CIGS at
all sites through this evening. Additionally, there will be a
threat of scattered showers through this evening with the best
chances north of point conception. Also, there will be the
possibility of isolated thunderstorms through this afternoon at
all terminal sites.

Klax... Moderate confidence in 18z taf. There is a 30% chance of
MVFR cigs. There is a 10-15% chance of thunderstorms 20z-02z. For
tonight, low confidence in potential return of MVFR cigs. There is
a 40 percent chance of east winds of 10 knots or more 10z-16z.

Kbur... Moderate confidence in 12z taf. There is a 30% chance of
MVFR cigs. There is a 10-15% chance of thunderstorms 20z-02z.

Marine 22 924 am.

For the outer waters, high confidence in current forecast. Both
winds and seas will remain at small craft advisory (sca) levels
today and tonight. On Thursday, the winds and seas will begin to
diminish, dropping below SCA levels. For Friday through Sunday,
winds and seas will remain below SCA levels.

For the inner waters north of point sal, high confidence in
current forecast. Winds will reach SCA levels this afternoon and
evening while seas remain at SCA levels through tonight. On
Thursday, winds and seas will drop below SCA levels with
conditions remaining below SCA levels through Sunday.

For the inner waters south of point conception, high confidence in
current forecast. Winds will remain at SCA levels through tonight.

For Thursday through Sunday, winds and seas are expected to
remain below SCA levels.

For today, a cold and unstable air mass will bring the threat of
isolated thunderstorms to all coastal waters. Gusty and erratic
winds, steep short-period seas, brief heavy rain and lightning
will be potential threats.

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 critera, 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
zones 34-35-40. (see laxcfwlox).

Beach hazards statement in effect through late tonight for
zone 41. (see laxcfwlox).

Pz... Small craft advisory in effect until 3 am pdt Thursday for
zones 645-650-655-670-673-676. (see laxmwwlox).

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.
