updated synopsis and aviation sections
Synopsis 23 255 pm.
Afternoon temperatures will cool a bit early in the week, warm
through the end of the week, then cool again during the weekend.
Overnight and morning low clouds and fog will develop along the
coast and at times will push into the adjacent valleys.
Short term (sun-wed) 23 1214 pm.
Current forecast is on track with anticipated cooling as onshore
pressure gradients increase and the marine layer deepens in
response to an approaching trof that will cross the northern
portion of the state between now and Monday. Lower heights along
with the aforementioned changes in the pressure gradients and
marine layer depth will insure cooler temperatures, especially
inland where the effects will have greater impact. The marine
layer depth this morning was around 1500 feet and should deepen
further by Monday morning.
Additional cooling can be expected on Monday as the trof continues
to traverse the northern portion of the state on its way to the
great basin. The marine layer will likely get into the valleys
Monday morning. One change for the afternoon package will be to
increase the winds in the antelope valley for Monday afternoon and
evening as the onshore gradient from lax-dag looks just as strong
Monday as it is today. Also, removed any hint of low clouds and
fog for the salinas valley tonight into Monday morning as the low
level moisture does not support any fog development.
For Monday night into Tuesday, there will not be too much change
in the low clouds and fog coverage as the even the la valleys will
again see some patchy low clouds and fog. However, the heights
start to rise and the onshore pressure gradients will weaken
enough to allow some warming across the forecast area, especially
in the mountains and deserts.
By Tuesday night into Wednesday, a rex block forms in the eastern
pacific, with a high latitude upper high and a cutoff low just to
its south. The cutoff low will be well off to the west and its
only effect will be to amplify a downstream ridge over southwest
california. Temperatures will rise across the entire district due
to higher heights and weaker onshore flow. At this point, the
marine clouds should become shallow enough to be restricted to
only the coastal sections.
Long term (thu-sun) 23 126 pm.
The warming trend will continue into Thursday, which should be the
warmest day of the next 7 days. High temperatures on Thursday will
soar close to triple digit territory in the warmest locations,
like the interior valleys and the deserts. Patchy low clouds and
fog should remain along the immediate coastal sections.
On Friday, the upper high off the pac NW coast breaks down and
allows trof energy to approach the washington and oregon coasts,
which in turn, will kick the cutoff low eastward and toward
northern california. Accordingly, heights will drop, the onshore
flow will again increase, and the temperatures will drop across
For next weekend, the extended models are in decent agreement that the|
cutoff low will push into far northern california on Saturday.
Little change is expected for Sunday, before another deeper trof
pushes into northern california early next week.
Aviation 24 0017z.
At 21z, the marine layer depth was around 1400 feet deep at klax.
The top of the marine inversion was around 1950 feet with a
temperature near 21 degrees celsius. There was another inversion
up to around 2400 feet.
Moderate confidence in the current forecast. Timing of could be
up to one hour earlier than forecast or up to two to hours later.
North of point conception, lifr to ifr conditions will spread
into coastal and coastal valley terminals through 08z. Conditions
should become predominantly lifr between 05z and 08z. There is a
chance of vlifr conditions between 08z and 14z.VFR conditions
should redevelop between 16z and 17z.
South of point conception, ifr to MVFR conditions will spread
into coastal terminals through 10z. Higher confidence in MVFR
conditions south of koxr. There is a chance of ifr to MVFR
conditions for valley terminals between 10z and 16z.VFR
conditions should redevelop between 16z and 18z.
Klax... MVFR conditions will spread into klax as early as 03z or
as late as 09z.VFR conditions should develop between 16z and
17z, but there is a 30 percent chance that MVFR conditions delay
until as late as 20z. Any east winds that could develop between
11z and 15z should remain less than 5 knots.
Kbur... There is a 40 percent chance of ifr to MVFR conditions
between 10z and 16z. No wind impacts are expected at this time.
Marine 23 202 pm.
For the outer waters... Winds across the northern and central
outer waters will strengthen to small craft advisory (sca) level
by this evening and the conditions will continue through early
Monday morning. Otherwise and elsewhere conditions will remain
below SCA levels through Thursday.
For the inner waters... Conditions will remain below SCA levels
Patchy dense fog with visibility one mile or less will form
across the coastal waters tonight through Monday morning. The
dense fog will be most prevalent north of point conception and in
the santa barbara channel.
Lox watches warnings advisories
Pz... Small craft advisory in effect until 3 am pdt Monday for
zones 670-673. (see laxmwwlox).
Hazard potential outlook (wed-sun)
No significant hazards expected.

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.
