Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
1031 AM PST Tue Dec 10 2019

Updated Aviation Section

.SYNOPSIS...10/812 AM.

A weak ridge of high pressure will give way to partly cloudy skies
through the week with temperatures near normal through Wednesday,
then above normal Thursday and Friday. Breezy northerly winds
will develop Wednesday and last into the weekend. A moderate Santa
Ana wind event is possible on Monday.

&&

.SHORT TERM (TDY-THU)...10/924 AM.

A large batch of high clouds moving through the area today, the
tail end of a system that stretches well up into Canada. Otherwise
pretty unremarkable weather today with highs very close to normal.

***From Previous Discussion***

A weak trof will push the ridge away tonight and then move over
the area. There is not enough moisture or dynamics with this trof
to produce rain just some some clouds. Northerly offshore pressure
gradients will form in the wake of the trof and this along with
some (minimal) cold air advection will bring about a north wind
event (sub advisory) focused down the i-5 corridor, the SBA south
coast and the area 10 miles either side of the LA/VTA county line.
The cool air advection will offset the offshore flow and max
temps will not change much.

The north winds will continue overnight before weakening and
shifting more to the northeast.

Ridging again develops across the southern half of the state on
Thursday. There will be about 3 MB of offshore flow from both the
east and north in the morning and this will kick off a weak Santa
Ana event. Nothing to write home about just 15 to 25 mph with
local gusts to 35 mph in the morning through and below the passes
and canyons. Like today the ridge will not be high enough
amplitude to deflect a stream of mid and high level clouds and
enough mid and high level clouds will be overhead to make it a
mostly cloudy morning. At this time it looks like these clouds
will taper off in the afternoon and there will be some sunshine.
Hgts will be well above normal so despite the clouds there will be
a nice 3 to 6 degree bump in temps and most cst/vly sites south of
Pt Conception will see Max temps in the lower to mid 70s or about
5 degrees above normal. Central Coast max temps will only be 2 or
3 degrees above normal.

.LONG TERM (FRI-MON)...10/319 AM.

Friday looks like it will be the nicest day of the weak. The ridge
and the weak offshore flow will persist but the mid and high level
clouds should be gone making for a sunny day with max temps 2 to 5
degrees above normal.

The ridge gets pushed to the south as some energy drops out of
the Gulf of Alaska. Flat NW flow will become more and more
cyclonic as Saturday progresses. Hgts will fall to about 565 DM.
The weak offshore flow will reverse to weak onshore. Clouds will
increase through the day. A small chc of rain will develop across
the interior later in the afternoon. Max temps will drop
everywhere and the csts and vly temps will not be able to escape
the 60s.

A weak trof will zip across the state Saturday night. It will
bring a slight chc of mtn rain which may extend into portions of
the vlys. The latest mdls and their ensemble members have started
to trend drier and even chc pops may be over done. The trof will
kick off a round of offshore winds fueled by moderate northerly
offshore grads and cold air advection. There will probably be some
advisory level gusts through the I-5 Corridor and the SBA south
coast.

Skies will be mostly sunny on Sunday but the cool air filtering in
behind Saturday night's trof will make it the coolest day of the
next 7 with cst and vly temps mostly in the lower to mid 60s.

A ridge builds in on Monday. There will be moderate offshore flow
from both the east and north and this should result in a Santa Ana
event with low end advisory gusts in the usual locations. Max
temps will rise a few degrees under sunny skies.

&&

.AVIATION...10/1830Z.

At 17Z KLAX...There was no marine layer, with a surface based
inversion up to 1400 feet and 14 degrees Celsius.

Low confidence on KPRB today, with LIFR cats lasting through 19Z
or 22Z. Moderate confidence of increase stratus coverage tonight
and Wednesday. High confidence in LIFR cats after 10Z at KPRB,
otherwise low confidence on if any stratus will be LIFR or IFR.
Stratus chances include: KSBP (70 percent) KSMX (80 percent) KSMO
(30 percent) KLAX (50 percent) KLGB (70 percent). Winds will be
lighter than usual.

KLAX...High confidence in VFR cats through at least 06Z. 50
percent chance of stratus with an start window of (08-12Z). IFR
cats most likely, but there is a 20 percent chance of LIFR. No
significant east winds expected.

KBUR....High confidence in VFR through Wednesday, except for a
10 percent chance of IFR CIGS 12-16Z Wednesday.

&&

.MARINE...10/907 AM.

Moderate confidence that winds will stay under Small Craft
Advisory (SCA) through Wednesday morning, with a long duration of
SCA conditions likely starting Wednesday afternoon, which will
continue through at least Sunday. These winds will be focused from
the Central Coast to San Nicolas Island, but will affect portions
of the Santa Barbara Channel and Santa Monica Basin at times,
especially over the weekend when the winds peak. Short period
choppy seas will become more prevalent everywhere.

A large and long period W to NW swell will impact the coastal
waters later Thursday and continue through Saturday, resulting in
hazardous sea conditions and large breaking waves near shore.
Breaking waves at the Morro Bay and Ventura Harbor entrances are
possible.

&&

.BEACHES...10/907 AM.

A large long-period west to northwest swell will push on to the
coast of central and southern California Thursday night, peak on
Friday, then slowly diminish over the weekend. Swells off the
Central Coast will likely peak at 12 to 15 feet and off the
southern waters 5 to 8 feet. High Surf Advisories will likely be
needed over all beaches during the peak, with strong rip currents
and dangerous breaking waves.

With high tides around 6.5 feet Friday and Saturday, minor
coastal flooding is possible during the late morning high tides.
Any coastal flooding impacts should be confined to the beaches,
with flooding possible in the most vulnerable parking lots, bike
paths, and walkways. There is a small chance of more impactful
flooding over vulnerable roads in the Ventura area.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
PZ...Small Craft Advisory in effect from 3 PM Wednesday to 3 AM
      PST Thursday for zone 650. (See LAXMWWLOX).
     Small Craft Advisory in effect from 3 PM Wednesday to 3 PM
      PST Saturday for zones 673-676. (See LAXMWWLOX).

&&

.HAZARD POTENTIAL OUTLOOK (THU-MON).

High surf is likely and minor coastal flooding is possible for
late this week at area beaches. Strong north winds possible
Sunday in southern Santa Barbara County, and parts of LA/Ventura
Counties.
