Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
1043 PM PDT Tue Apr 1 2025

.SYNOPSIS...01/134 PM.

Cool and unsettled weather is expected through this evening with
low snow levels and gusty winds. Wednesday is expected to be dry
but with continued cooler than normal temperatures. Showers are
again possible Thursday, mainly south of Point Conception as
another upper low moves through the area. Dry weather is expected
from Friday through at least early next week with significant
warming over the weekend. By Sunday high temperatures will be 5 to
10 degrees above normal.

&&

.SHORT TERM (TUE-FRI)...01/1043 PM.

***UPDATE***

A cold upper level low moved into southern California today,
bringing very gusty northwest winds and isolated to scattered
convective showers, especially for San Luis Obispo and Santa
Barbara Counties. Winds were quite strong today, especially for
the Ventura County Coast and the western LA County Coast into the
Santa Monica Mountains, where gusts reached 82 mph at Sandstone
Peak. Plenty of areas saw gusts in the 30-50 mph range.
Temperatures today trended about 6 to 16 degrees below normal,
with highs in the 50s to mid 60s.

Looking into tonight, the deep upper level trough will continue to
hang over the area, cycling a number of lows through the region.
Rain and snow showers are possible for the north slopes, and
lingering moisture may lead to some scattered convective showers
over the interior Wednesday afternoon into Wednesday night,
before the next low moves in Thursday. Given the 500 mb
temperatures around -25 degrees, there is a chance for
thunderstorms along with more widespread convective showers that
will most likely initiate off of the higher topography Thursday.
Will see a dramatic change as this deep upper level trough moves
east, bringing a warmer airmass to the area Friday. The current
forecast looks on track, but will consider more wind advisories
for Wednesday along with expanding shower chances for the interior
Wednesday afternoon.

***From Previous Discussion***

An upper low is moving into the interior of northern California
with some showers well ahead of it that have dropped some light
rain across parts of the Central Coast and some light snow over
the Grapevine region. With the flow aloft strongly from the north
the Transverse range is preventing the showers from reaching the
valleys and coastal areas south of Pt Conception, however those
areas will be experiencing some very gusty west to northwest
winds through the evening and wind advisories are in effect.
Showers will taper off overnight as the upper low moves into AZ
and the air mass briefly dries out.

Wednesday is expected to be dry and cool with some gusty
northwest winds at times. Hi temperatures will range from 5-15
degrees below normal. Coolest across the interior.

Another batch of colder air aloft will move into the existing
trough across interior California on Thursday which will increase
instability and provide a favorable environment for showers and
possibly even an isolated thunderstorm, but this time mainly
south of Pt Conception. 12z ensembles we're not quite as on board
with this idea as earlier runs so if these trends continue shower
chances for Thursday may have to be lowered. Overall amounts will
be light, but could be some brief moderate to heavy rain, with the
best chances for that across southeastern LA County where the best
convergence and instability will be. And once again snow levels
will be on the lower side, generally 3500-4500 feet.

On Friday the main trough finally exits to the southeast with what
is expected to be the beginning of an extended period of dry
weather with warming temperatures.

.LONG TERM (SAT-TUE)...01/225 PM.

Models continue to advertise high pressure building over the area
this weekend leading to a significant warming trend, bringing
temperatures up to a few degrees above normal Saturday and 4-8
degrees above normal Sunday, with warmer valley highs close to 90
and coastal areas upper 60s and 70s.

A weak trough passing well to the north Monday will slow down the
warm up briefly before a stronger ridge moves in Tuesday and
Wednesday with even warmer temperatures expected.

&&

.AVIATION...01/2352Z.

Around 00Z, there was no marine layer or inversion.

High confidence in widespread VFR conds, and moderate confidence
in winds. Gusty W to NW winds will affect most terminals through
the period, with relative lulls possible during the overnight
hours before increasing again in the morning Wednesday. There is
a moderate chance of moderate to locally strong LLWS and turbc
through 06Z, then low to moderate LLWS and turbc after 18Z.

There is a 20-30 percent chance of brief showers with MVFR
cig/vsby conds through 08Z north of Point Conception. BLDU may
create lower vis at KPMD and KWJF.

KLAX...High confidence in VFR conds and moderate confidence in
winds, as gusty west winds will impact the terminal through most
of the period, with relative lulls during the overnight hours. Low
to moderate turbc and LLWS is possible through 06Z. No east wind
expected.

KBUR...High confidence in VFR conds and moderate confidence in
winds. There will be relative lulls in the winds overnight before
increasing in the morning Wednesday. There is a moderate chance
of moderate to locally strong LLWS and turbc through 06Z, then low
to moderate LLWS and turbc after 18Z.

&&

.MARINE...01/835 PM.

High confidence in the current forecast. Widespread GALES across
the southern Outer Waters and the Inner Waters south of Point
Conception are highly likely into late Wednesday night or early
Thursday morning. Winds may dip under GALE thresholds at times
Wednesday morning. SCA conds will continue into at least Thursday.

Elsewhere, Small Craft Advisory (SCA) winds and seas are expected
(90-100 percent chance) through at least early Thursday morning,
with a 60-80 percent chance SCA conds continue through Thursday
evening. There is a 30-40 percent chance of GALES extending into
the northern and remaining outer waters at times through Wednesday
evening.

Chances for SCA conds decrease (40-60 percent chance) across the
coastal waters Friday through the weekend.

Dense fog may develop this upcoming weekend, especially in the
evening to morning hours, in response to a ridge building over
the region.
