910 pm pdt Fri apr 20 2018

Synopsis 20 508 pm.

A high pressure system will bring above normal temperatures
away from the coast through Monday. Closer to the coast, a
coastal eddy will usher in night through morning low clouds and
fog. A low pressure system should arrive Tuesday for increasing
onshore flow and a cooling trend through the remainder of the work
week.

Short term (fri-mon) 20 909 pm.

The latest satellite imagery shows an upper-level ridge of high
pressure building into central california this evening and a
farther upstream trough about 400 miles west of seattle. A weak
upper-level trough sits near 27n and 128w, or about 700 miles
southwest of los angeles.

Ridging aloft will remain in place through Saturday and onshore
flow will weaken through Saturday, possibly turning weakly
offshore later tonight. A warming trend will take place on
Saturday, especially away from the coast. Much of the warming near
the coast will depend how much marine intrusion takes place into
Saturday morning. There is a chance that temperatures near the
beaches could be a tad too warm Saturday. Fog product imagery
does not look particularly impressive, but some semblance of
marine layer stratus is present giving some confidence in the
overall stratus forecast through Saturday.

The trough of low pressure to the southwest of the area will move
northeast into the southern california on Saturday afternoon,
while the trough to the northwest phases and fills in behind it.

A cooling trend should develop for Sunday and Monday. Below
normal temperatures and a persistent marine layer should remain
in place for early next week.

*** from previous discussion ***

Long term (tue-fri) 20 158 pm.

Models seem to have settled down on a solution for next week,
keeping the upper low well west of the coast through at least the
middle of the week, then lifting it northeast into the pac nw
Friday night into Saturday. This will keep some ridging along the
coast going through mid week at least, however onshore flow
strengthens slightly each day. So it looks like the marine layer
should be a consistent feature for coast and coastal valleys next
week with temps near to slightly above normal. A strong onshore
push will likely cool temps to below normal by the end of the week
with some gusty winds in the antelope valley.

Aviation 21 0003z.

At 22z, the marine layer depth was around 1800 feet deep at klax.

The top of the inversion was near 2500 feet with a temperature
around 17 degrees celsius.

Moderate-to-high confidence in the current forecast. High
confidence in timing, moderate confidence in flight categories.

North of point conception...VFR conditions are expected through
at least 03z, then there is a chance of lifr to ifr conditions at
coastal terminals through 10z.VFR conditions are expected
throughout the remainder of the period.

South of point conception...VFR conditions are expected through
at least 08z, then there is a chance of ifr to MVFR conditions at
coastal terminals through 16z. The highest chance of sub-vfr
conditions is expected at los angeles county coastal terminals.

There is a very slight chance that MVFR conditions could linger at
coastal terminals through Saturday afternoon.

Klax...VFR conditions are expected through at least 08z, or as
late as 13z. Then, there is a 60 percent chance of ifr to MVFR
conditions through 16z. There is a 10 percent chance that MVFR
conditions could linger through 20z.

Kbur...VFR conditions are expected throughout the period, except
for 10 percent chance of ifr to MVFR conditions between 13z and
15z.

Marine 20 745 pm.

Low confidence in the fog forecast, but dense fog is possible now
through the weekend. High confidence in widespread short period
seas tonight, caused by gusty northwest winds over the outer
waters. The seas should
high confidence in small craft advisory (sca) winds from the
central coast to san nicolas island through tonight, with weaker
and more borderline SCA over the outer waters through the
weekend. Over the inner waters from the santa barbara channel to
the san pedro channel, SE winds will form each morning, up to 15
kt through the passages and channels, with accompanying choppy
seas. Typical onshore winds expected in the afternoon, with near-
sca west winds in the far western santa barbara channel.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 3 am pdt Saturday for
zones 645-676. (see laxmwwlox).

Small craft advisory in effect until 3 am pdt Sunday for
