Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1215 AM PDT Mon Apr 26 2021

.SYNOPSIS...25/728 PM.

There is a chance of light rain across the region through midday
Monday and it may linger into the evening over the mountains.
Afternoon temperatures will be cool through Monday then will warm
to well above normal on Thursday and Friday. Some inland locations
could warm into the 90s on Thursday and Friday.

&&

.SHORT TERM (MON-THU)...25/800 PM.

Cold upper level low pressure system centered over northern
California this evening will track southeastward into Northern
Nevada by Monday morning. Associated weak cold front has brought
some light rain to the region, mainly from Ventura county
northward. As of 8 pm, most of the automated rain gauges have
recorded less than 0.10 inches, with a few mountain stations in
Ventura and Santa Barbara counties recording between 0.10 and
0.16 inches. An approaching upper level 90 knot jet from the
southwest has helped to organize this light precipitation during
the past few hours. While much of the forecast area is expected to
see less than 0.10 inches through Monday, high resolution model
data continues to indicate localized amounts of 0.25 inches or
greater across the mountains of Ventura and Santa Barbara counties
where there will be enhanced southwest upslope flow. The weak cold
front will continue to track southeast overnight, bringing rain
chances to LA county. Snow levels are ranging between 5000 and
6000 feet this evening, and are expected to lower to between 4500
and 5500 feet overnight into Monday morning. We could see 1 or 2
inch accumulations above 6000 feet, but not expecting any snow
impacts on Interstate 5 near the Tejon Pass.

Fairly strong onshore pressure gradients remains in place this
evening, along with enhanced southwest upper level flow. As a
result, wind advisories remain in effect for the LA county
mountains and Antelope Valley through 11 pm, where we have seen
wind gusts of 35 to 45 mph today. There will be some lingering
light rain chances on Monday across LA county, and the north
facing mountains.

*** From previous discussion ***

On Tuesday, conditions will start to rebound. With more sunshine
and weaker onshore gradients, temperatures will begin to rebound
across the area. One thing to watch on Tuesday will be some
lingering mid-level moisture over the southern mountains. Current
forecast has a slight chance of showers Tuesday afternoon over the
San Gabriel Mountains which will remain in place. However, models
indicate a bit of an increase in instability Tuesday afternoon.
So, will need to monitor the potential for isolated thunderstorms
over the San Gabriels although current chances of any thunder are
below mentionable levels.

For Wednesday, upper level ridge will build in from the west as
the upper low moves across northern Mexico. Additionally, there
will be some weak offshore flow across the area in the morning.
So, will expect a noticeably jump in temperatures for the area
with many coast and coastal valley areas in the mid 70s to mid
80s. Additionally, there will likely be some localized northeast
winds, but speeds will be below advisory levels.

.LONG TERM (FRI-MON)...25/130 PM.

For the extended period. models continue to exhibit good synoptic
agreement. At upper levels, ridge will be entrenched over the area
Thursday/Friday then will be flattened/pushed eastward on
Saturday and Sunday as a trough moves across the West Coast. Near
the surface, weak offshore flow is expected Thursday/Friday with
increasing onshore flow Saturday/Sunday.

For Thursday/Friday, expect very warm and dry conditions with
ridge overhead and weak offshore surface gradients. The ECMWF is
slightly more bullish with the ridge and offshore gradients than
the GFS, resulting in a slightly warmer forecast. Either way, many
areas on Thursday/Friday can expect temperatures in the 80s to mid
90s with slightly cooler conditions near the coast. There will be
some weak northeasterly winds on Thursday/Friday, but do not
anticipate any advisory-level issues.

For Saturday/Sunday, onshore flow will return to the areas as
trough moves across the West Coast. So, will anticipate an
increase in coastal stratus/fog as well as a noticeable cooling
trend.

.AVIATION...26/0714Z.

At 0505Z at KLAX, There was no marine layer nor a sfc based
inversion.

Low confidence in coastal and vly TAFs as marine layer clouds will
form and dissipate in a fairly random manor. Cigs will likely vary
from IFR to MVFR xcp for KSMX and KSBP where there is a 30 percent
chc of LIFR cigs. There is a 30 percent chc that there will be
SCT conds at any given site after 19Z. Continued low confidence
after 00Z due to uncertainty in low cloud reformation.

KLAX...Low confidence in TAF. Cigs will likely form and dissipate
in a random manor through 17Z. Good confidence there will be no
cigs lower the BKN012. Better confidence after 17Z with a 30
percent chc of SCT conds. Low confidence again aft 03Z due to
uncertainty with arrival timing and hgt of low cigs. Very good
confidence there will not be any east wind component greater than
3 kt.

KBUR...Low confidence in TAF. Cigs will likely form and dissipate
in a random manor through 17Z. Better confidence in TAF after
17Z.

&&

.MARINE...25/724 PM.

There is a chance of light rain through Monday across the coastal
waters. Widespread short period seas will become elevated Monday
night and persist through the week, but will remain below SCA
level.

Across the Outer Waters... Small Craft Advisory (SCA) level winds
are possible Monday afternoon through Friday and will be
strongest during the afternoon and evening hours. Otherwise,
conditions will remain below SCA level.

Across the Inner Waters north of Point Sal... SCA level winds are
possible Monday afternoon through Friday and will be strongest
during the afternoon and evening hours. Otherwise, conditions will
remain below SCA level.

Across the Inner Waters south of Point Conception... Winds will
possibly be SCA level Monday afternoon through Friday from Point
Conception to Point Mugu and will be strongest during the
afternoon and evening hours. Otherwise and elsewhere, winds will
be elevated but will remain below SCA level.
