206 pm pdt Wed apr 26 2017
There may be possible precipitation in the ventura mountains
early Thursday. A high to the west... And a low to our east will
bring fair skies... Gusty winds and above normal temperatures into
Sunday. The high will move in by Monday for fair skies... With an
onshore flow to start a cooling trend at the coast.
Short term (tdy-sat)
latest satellite imagery showed mid to high level clouds
approaching the central coast ahead of a shortwave trough moving
southeast through central california. Patchy marine stratus
is hanging on off the central coastal. Otherwise sunny skies
except for partly to mostly cloudy skies developing with mountain
wave activity, most prominent to the lee of the tehachapi mtns
across the los angeles mountains into the antelope valley.
Temperatures so far today are matching up well with forecasted
highs to the west of the mountains. However, some areas north of
point conception and across the interior will likely fall several
degrees short of forecasted highs due to increasing cloud
A shortwave trough will pass to the east of the forecast area
this evening, bringing increasing cloudiness to interior areas with
a slight chance of upslope showers for north facing slopes. It
will also reinforce northerly winds to southwest california
beginning this evening. Strong upper level support with feature
has prompted the issuance of a high wind warning across the los
angeles and ventura county mountains, for this afternoon through
Friday morning. However, there may be a brief lull in warning
level winds across the area sometime Thursday afternoon. Advisory
level northwest to north winds will become more widespread this
evening with the san gabriel valley being the latest addition to
wind advisories. A second shortwave trough is expected to pass to
the east again Thursday evening, supporting continued unseasonably
gusty northerly winds to many of the same areas experiencing the
gusty winds this evening through Thursday morning. Winds will
probably remain just below advisory levels for coastal areas of
the central coast Thursday afternoon and evening.
Friday into Saturday a long wave trough deepens across the four
corners region as it gradually shifts east. Surface high pressure
building in behind the strengthening trough will support a
transition to more northerly winds Friday and offshore by
Saturday. Winds are expected to weaken during this time but will
still likely be advisory levels for wind prone areas. As a result,
current wind advisories across the mountains and some valley
areas will likely need to either be extended through early
Saturday or reissued.
Interior areas will see little change in temperatures through
Friday with some warming possible Saturday as a ridge aloft
nudges closer to california with mostly sunny skies. Areas west
of the mountains, especially south of santa barbara will
considerable warming and drying through Saturday due to the
downsloping winds off the mountains. High temperatures projected
to be around 10 degrees warmer then todays highs with low to mid
90s possible across the warmest valleys. It will be among the
warmest temperatures so far this year with low end heat impacts
possible, especially for at risk populations such as the young,
elderly, and unprepared.
Long term (sun-wed)
good confidence in the forecast through Monday with moderate
confidence Tuesday and Wednesday. Weakly offshore or near neutral
surface pressure gradients Sunday morning are expected to shift
moderately onshore by the afternoon providing notable relief from
the heat for coastal areas. However, downsloping winds combined
with a ridge of high pressure aloft will provide some warming
across interior areas. Onshore flow will likely continue into
Monday with continued cooling across coastal areas into the
valleys and little change across interior areas. Low clouds and
patchy fog are possible as early as Monday morning, but more|
likely overnight Monday into Tuesday morning. Model guidance is
hinting an offshore push providing near neutral to offshore
surface gradients by Wednesday. This may hamper cooling currently
advertised as well as limit marine layer influence to the west of
At 1718z, there was no marine layer at klax.
There was good confidence in the 18z tafs. The biggest concern
remains the strong gusty north to northwest winds across the
region. Hazards for today include low level wind shear, turbulence
resulting from uddfs, and reduced visibility in blowing dust and
sand.VFR conditions will continue predominant at the TAF sites
other than the possibility of patchy fog late on the central
coast and in the salinas valley, and the possibility of blowing
dust in the antelope valley this afternoon.
Klax... High confidence in the 18z TAF in that conds should beVFR
through the pd. Winds will be more tricky. There is a 30% chance
of northerly cross winds over 20 kt from 01z to 09z this evening.
Bur... High confidence in the 18z TAF in that conds should beVFR
through the pd. There is a 50 percent chance of wind gusts over
25 kt from the northwest to northeast from mid afternoon through
Marine 26/200 pm
for the outer waters, high confidence gale force winds through
Friday night, with SCA conditions, at least,likely through
For the inner waters, moderate to high confidence in SCA conds
through Fri night. There will likely be some gale force gusts,
especially across western sections. There is a 20-30% chance that
gale warning may be needed, especially late Thu through fri
Due to strong winds throughout the waters, seas will be very
choppy in all areas this week, making for hazardous boating
conditions through the week.

34-35. (see laxnpwlox).

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.
