Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
539 PM PDT Mon May 16 2022
.SYNOPSIS...16/230 PM.
Gusty northwest to northeast winds will persist through Thursday
or Friday. Near normal temperatures will continue through Tuesday,
warming 5 to 10 degrees Wednesday and Thursday with high pressure
strengthening aloft. Coastal areas will remain under a seasonal
marine layer through the week.
&&
.SHORT TERM (TDY-THU)...16/227 PM.
The latest satellite showed low clouds sticking around, mostly
just offshore in a eddy formation. Onshore flow was pushing some
of the clouds into some beaches of LA county. Temperatures were
trending about as expected with the notable exception of the SBA
county South Coast which remains under the influence of the marine
layer. However, for stronger Sundowner events such as today we
often see daytime highs in the late afternoon and sometimes even
evening, which is a distinct possibilty for today.
Moderate northwest to onshore surface pressure gradient trends
will support the slew of advisories that expand across the LA/VTA
mountains to the Antelope valley this afternoon. Although the
LA/VTA mountain advisories are marginal with a 30 percent chance
that gusts largely remain below advisory levels. The high wind
warning for southwest SBA county looks good with the typical
windier locations from Refugio to Gaviota having a good shot at
wind gusts peaking between 50 and 60 mph later this afternoon into
tonight.
The moderate to strong northwest flow atop the region will likely
provide a boost to the eddy circulation tonight, providing another
round of low clouds to most coastal areas and some lower valleys,
perhaps even nosing into the San Fernando Valley and Oxnard plain
once again around sunrise. The push from the north may bring low
clouds and fog into the Salinas Valley near Paso Robles as well.
A compact and weak upper low will pass overhead Tuesday,
reinforcing northwest to north flow atop the region. albeit
considerable weaker than what we are expecting for later today
into tonight. Even still, southwest SBA county will probably reach
low end wind advisory gusts with a 30 percent chance of advisory
level gusts for the I-5 corridor through the mountains.
A short-wave ridge will nose into the region from the west
Wednesday with above normal 500 mb heights near 585 dm supporting
an uptick in temperatures, especially for interior areas where
widespread 90s are likely. The increased weight from the heavier
atmosphere will try and likely succeed in squashing the marine
layer and somewhat decrease the inland penetration of night to
morning low clouds for the Central Coast. South of Point
Conception is not as clear cut with competing factors between the
ridge and likely continued eddy circulation. The current forecast
calls it a draw, maintaining a marine layer depth around 1500 feet
which would push low clouds and fog into coastal and some lower
valleys (especially the San Gabriel Valley).
A much stronger and broader trough drop into the Great Basin
Thursday into Friday. Often utilized persistence forecasting will
go out the window for this time frame as significant height and
pressure falls to our east drive strong onshore trends and overall
flow by Thursday afternoon. This will likely support a rapid
deepening of the marine layer Thursday and may support clouds
hanging around much of the day for some beaches. Several degrees
of cooling is expected for most, although compressional heating
from downsloping flow across interior foothills may mitigate some
of the cooling.
.LONG TERM (FRI-MON)...16/227 PM.
The aforementioned trough will swing east into the Central
Rockies Friday, with high pressure building in its wake. The net
result will be strong offshore trends, most notably from the east.
The quick hit nature of the system will likely limit the strength
of offshore winds, which will probably remain below advisory
levels and may even be quite limited west of the mountains should
the marine layer remain in place. Before offshore flow takes hold,
patchy drizzle will be possible Friday morning, especially for
favorable foothill locations in response to the rapidly deepening
marine layer Thursday night into early Friday. The rapid push and
pull of the pressure gradients and colder air aloft will weaken if
not completely dissipate the marine layer and associated low
clouds/fog by Friday.
Ensemble guidance (GEFS ECS GEPS) is a bit all over the place next
weekend, decreasing forecast confidence. However, it seems that
there is a trend towards some lingering troughiness to the region
with only gradually rising 500 mb heights. This pattern should be
supportive of re-establishing the marine layer (and associated
night to morning low clouds) likely at a seasonal level between
1-2K feet. Temperatures will rebound to above normal values over
the weekend, with the potential more significant heat just beyond
the official forecast window early next week.

.AVIATION...17/0038Z.
At 2331Z at KLAX, the marine layer was 1200 ft deep. The top of
the inversion was at 3300 feet with a temperature of 22 Celsius.
High confidence in desert TAFs, moderate confidence in all others.
Timing of flight cat changes could be off by +/- 2 hours. There
is 20% chance of brief IFR/LIFR at KPRB 11-15Z. There ic a 20%
chance that KSBP remains VFR thru the period. Chance of BKN008-12
at KVNY (20%) and KBUR (40%). High confidence in VLIFR at KSMX
early Tuesday. Chance of sporadic northwest gusts and LLWS 15-20
knots at KSBA 01-08Z.
KLAX...Moderate confidence in TAF. Timing of flight cat changes
could be off by +/- 2 hours. There is a 40% chance of an east wind
component reaching 10 knots 10-15Z.
KBUR...High confidence in TAF thru at least 08Z, then moderate
confidence. Timing of cat changes could be off by +/- 2 hours. 40
percent chance of BKN008-012 starting 10-14Z.
&&
.MARINE...16/208 PM.
An extended period of Gale force winds will be common through at
least Thursday or Friday for the outer waters from the Central
Coast to San Nicolas Island. This will create steep short period
waves over all coastal waters through at least Thursday, with
ample white caps for hazardous sea conditions.
For the nearshore waters along the Central Coast, Small Craft
Advisory (SCA) level winds are likely each day through at least
Thursday for the afternoon and evening hours.
For the Santa Barbara Channel, high confidence in Gale Force winds
developing by this evening and staying confined to the western
half. dangerous winds likely between the Channel Islands west of
Santa Cruz Island. Widespread steep waves likely. Winds should
retreat to the west starting Tuesday, but could affect the far
western portion.
For the Santa Monica Basin, San Pedro Channel, Orange County area,
high confidence in typical west afternoon winds (10 to 15 knots).
Local gusts to 25 kt possible beyond 20 miles from shore, and in
the San Pedro Channel this afternoon and night. Choppy seas likely
each afternoon and night. A Small Craft Advisory was issued to
address mainly for the choppy seas from nearby winds.
High confidence in all nearshore waters south of Point Conception
will see moderate southeast winds each morning, with isolated 15
to 20 knots possible near San Pedro and Point Mugu.
