Synopsis
An approaching low pressure system will spread marine layer clouds
and below normal temperatures farther inland tonight through Saturday.

There is a chance of drizzle tonight into early Thursday... And
again Thursday night into Friday. A ridge of high pressure will
build over the area this weekend... And a warming trend will bring
temperatures back to near or above normal by early next week. In
addition, the marine layer clouds will be confined to near-coastal
areas.

Short term (wed-sat)
a well-developed marine layer stratus deck is taking shape this
evening as a trough of low pressure approaches the area. The
trough of low pressure about 300 miles offshore of the central
coast will slowly drift into the southern california bight through
Friday morning. Strong onshore flow and a deepening marine layer
will bring a cooling trend through Friday. If NAM bufr time height
sections are correct, the marine layer should deepen to near 4000
feet deep by Thursday morning and to 5000 feet deep by Friday
morning. Klax-kdag and ksmx-kbfl surface pressure gradients are
strongly onshore this evening and should strengthen additionally
on Thursday afternoon.

With the trough nudging closer to the area, patchy drizzle or
light showers cannot be ruled out as the marine layer deepens and
interacts with the upper-level dynamics associated with the weak
weather system over the next couple of days. Pops have been nudged
up across the area and mentions of drizzle have been added to the
central coast tonight through Thursday morning.

With strong onshore pressure gradients, gusty southwest winds will
likely develop across the interior valleys the next couple of
days. The wind advisory for the antelope valley has been extended
into Thursday evening, but it reasonably could be extended into
Friday or Friday evening. Future shifts may also need to consider
a wind advisory for the san luis obispo county valleys for
Thursday afternoon and evening. Model guidance for kprb is
suggesting winds strengthening above advisory level criteria, but
there has been discontinuity across the model guidance. For now,
any decisions on expanding a wind advisory for the san luis obispo
county valleys will be tabled for more data and better agreement.

*** from previous discussion ***
with the trough axis moving through Friday night there should be
much earlier and complete clearing of the marine lyr Saturday.

Highs expected to be a few degrees warmer though still below
normal.

Long term (sun-wed)
a high amplitude upper ridge will develop along the west coast
Sunday and Monday. At the same time onshore flow will be weakening
and daytime temps are expected to climb to several degrees above
normal by Monday. Another weak upper low is expected to undercut
the ridge Tue Wed forcing a deepening of the marine lyr and cooler
temps.

Aviation 25 0000z.

At 00z, the marine layer depth at klax was near 1700 feet. The
top of the inversion was around 3200 feet with a temperature of 21
degrees celsius.

Moderate confidence in the current forecast. Ifr to MVFR
conditions will likely spread into most coastal and valley
terminals through 08z. Ifr conditions are likely in any drizzle,
mainly between 07z and 16z. MVFR conditions will likely linger
through much of the day at coastal and valley terminals.

Klax... There is a 80 percent chance of MVFR conditions throughout
the period. Between 03z and 15z, there is a 60 percent chance of
ifr conditions in drizzle. After 20z, there is a 30 percent chance
thatVFR conditions could develop; however, ceilings at or below
5000 feet will likely persist. South winds around 10 knots are
possible between 13z and 17z.

Kbur... Ifr to MVFR conditions will likely spread into kbur between
04z and 08z. There is a 60 percent chance of ifr conditions in
drizzle between 07z and 15z. After 20z, there is a 40 percent
chance thatVFR conditions could develop; however, ceilings at or
below 5000 feet will likely persist.

Marine 24 800 pm.

Mainly light winds are expected across the coastal waters through
Friday. Northwest winds will begin to increase Saturday afternoon,
with a 50% chance of SCA gusts by Saturday evening over the outer
waters. Over the nearshore waters north of point sal, SCA winds
will be possible Sunday and Monday. For the nearshore waters south
of point conception, conditions are likely to remain below sca
criteria through the period.

Patchy fog and drizzle should affect all the waters from midnight
through around noon on Thursday.

Lox watches warnings advisories
Ca... Wind advisory in effect until 9 pm pdt Thursday for zone 59. (see laxnpwlox).

Pz... None.

Hazard potential outlook (sat-wed)
no significant hazards expected.
