846 pm pdt Wed jun 19 2019

Synopsis 19 818 pm.

Clouds will increase at the coast and valleys Thursday as onshore
winds strengthen. Through the rest of the week, expect clear
skies in interior areas with clouds persisting at the coast.

Patchy morning fog and drizzle are possible at the coast and
valleys. Temperatures will cool through Friday and warm slightly
into the weekend as clouds dimish.

Short term (wed-sat) 19 846 pm.

Upper level ridge of high pressure will weaken and shift eastward
as a fast moving upper level trough moves into northern and
central california on Thursday. This will lead to strengthening
of the onshore pressure gradients and a deepening of the marine
layer, resulting in a cooling trend across the district. Already
seeing stronger onshore pressure gradients this evening, with
lax-daggett currently at +8.6 mb this evening (as compared to +7.4
mb this time yesterday). By tomorrow afternoon evening, expecting
lax-daggett gradient to peak over +10 mb onshore.

00z vandenberg sounding and acars data over lax basin indicating
a rather uniform marine layer depth this evening around 2500 feet.

The upstream upper level trough combined with the strengthening
onshore gradients is expected to deepen the marine layer to
between 3000 and 3500 feet on Thursday morning, and most likely
even deeper by Friday morning. In evening update, will expand the
low clouds and fog into the lower coastal slopes. This
deepening marine layer pattern will likely result in widespread
drizzle across the region overnight into Thursday morning, and
again Thursday night into Friday morning. In fact, there is a
chance of some measurable light rain across la county, mainly in
the foothills and coastal slopes, especially on Friday when we are
carrying 20-30 percent pops. As we would expect with a deep
marine layer and strong onshore flow pattern, look for low clouds
to linger all day across the coastal plain, and possibly some of
the valleys.

Onshore winds picking up this evening across the antelope valley,
and will continue to strengthen into Thursday, with little change
into Friday. Wind gusts between 40 and 50 mph will be common
across the antelope valley both days, mainly during the afternoon
and evening hours, with isolated gusts as high as 60 mph in the
foothills (near lake palmdale). A wind advisory has already been
posted for these strong onshore winds tomorrow afternoon evening
across the antelope valley. Elevated fire weather conditions
are expected across the antelope valley and adjacent foothills
due to these strong onshore winds, fairly low humidities, and
abundant grass crop. Valley temperatures expected to remain
in the 70s on Thursday, with Friday likely being the coolest day
of the week (when some interior areas being 12 to 15 degrees below
normal).

*** from previous discussion ***
very weak ridging is expected Saturday and the winds will trend
offshore helping the marine layer clouds clear earlier and
allowing afternoon high temperatures to rise a few degrees.

Long term (sun-wed) 19 208 pm.

By Sunday, temperatures will be near normal across the interior
but will still be 5 to 10 degrees below normal across the coasts
and valleys. Another trof will arrive Monday, this time from the
northwest. We'll have westerly zonal flow aloft on Monday as
we're just south of the trof, then the lower heights work their
way south through Wednesday. The low will bring back the strong
onshore flow, less clearing and cooler coastal temperatures.

Aviation 20 0019z.

At 2034z, the marine layer depth was around 2400 feet deep at
klax. The top of the inversion was near 3400 feet with a
temperature around 21 degrees celsius.

Moderate confidence in the current forecast. The latest visible
sattelite imagery trends show considerable marine layer coverage
over the coastal sections of ventura and santa barbara counties
with clear skies over the la county coastal areas. The latest mos
guidance and mesoscale models are supportive of marine layer
moving onshore to the la county coastal areas by 03z-04z... And by
04z-05z over the inland valleys. As an upper level trough deepens
across the region, deeper marine layer will set up across much of
the coastal and inland valleys through the 00z TAF period with
limited clearing tomorrow afternoon. Terminals over the antelope
valleys should see continued gusty W wsw winds overnight into
tomorrow with tightening onshore pressure gradient.

Klax... Expect MVFR ceilings to develop by around 03z-04z... With
limited clearing tomorrow afternoon due to the deeper marine
layer.

Kbur... Expect MVFR ceilings to develop by around 04z-05z... With
ifr CIGS and MVFR visby in light fg by early tomorrow morning.

MVFR ceilings will persist tomorrow though a brief period of
parital clearing can be seen 20z-00z.

Marine 19 814 pm.

Winds and seas will likely remain below small craft advisory
levels through at least Thursday. There is a 50 percent chance
for advisory level seas and winds across the northern most outer
waters Friday afternoon and evening, and a 30 percent chance of
advisory level winds each afternoon and evening through the
weekend.

Lox watches warnings advisories
Ca... Wind advisory in effect from 2 pm to 10 pm pdt Thursday for
zone 59. (see laxnpwlox).

Pz... None.

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