Area forecast discussion, Nov 15, 9:58 PM PST, 4 hours 2 minutes before
Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
958 PM PST Fri Nov 15 2019
.SYNOPSIS...15/756 PM.
Temperatures will be warm this weekend as high pressure moves
into the region. With clear skies and 80s to low 90s expected
through the coast and valleys, a few record high temperatures
could be reached. The pattern will shift again around mid week as
a low pressure moves in bringing clouds, cooler temperatures and a
chance of rain.
&&
.SHORT TERM (FRI-MON)...15/852 PM.
Weak upper level low pressure system off the coast of Southwest
California will shift southward and become centered off the coast
of northern Baja by Saturday morning. The rising heights and
offshore pressure trends will lead to a shrinking marine layer
depth overnight into early Saturday morning. As a result, there
is the potential for areas of low clouds and dense fog later
tonight into Saturday morning across the LA county coastal
plain and Salinas River Valley near Paso Robles. By Saturday
morning, the LAX-Daggett pressure gradient is expected to
reach -3.0 to -4.0 mb, which will lead to offshore winds
gusting between 25 and 40 mph across wind prone areas of
Los Angeles and Ventura counties. The offshore winds combined
with rising heights/boundary layer temperatures will lead
to a significant warming trend with highs in the mid 80s to
around 90 degrees on Saturday.
Models continue to trend upward in the offshore gradient for
Sunday morning, with peak LAX-Daggett gradient around
-5 mb. Still expecting peak wind gusts in the Santa Ana wind
prone areas of Ventura and LA counties to range from 25-40 mph
coast and valleys to 50 mph in the mountains and foothills.
Sunday remains as the gustiest and driest day for this event.
Some additional warming on Sunday will result in a smattering
of record highs in the mid 80s to lower 90s for coastal and
valley areas.
*** From previous discussion ***
Gradients weaken some on Monday and temps and winds
decrease across coastal and valley areas as a result, however
conditions will remain dry. Critical fire danger will be the
primary concern, especially Sunday, and even elevated levels are
likely on Monday due to residual dry conditions. See the fire
weather discussion below for more details.
.LONG TERM (TUE-FRI)...15/209 PM.
Heights begin to fall on Tuesday, which will be a transition day
between the weekend's Santa Ana and our first rain of the season
that'll hang around mid to late next week. Deterministic models
generally in good agreement in dropping a sharper trough southward
along the west coast from west of OR/WA, and Tuesday the trough's
center will be centered somewhere just off northern California.
The lowered heights along with a switch to onshore flow will cool
temps 5 to 10 degrees most areas (largest cool down coast and
valleys) while clouds increase from north to south by later in the
afternoon. This sets up an extended period of cool, damp, and
cloudy weather from Wednesday through Friday.
Expected precip timing, amounts, and certainty haven't changed
much versus previous forecasts. In addition, the EC deterministic
solution and its ensemble mean continue to be more enthusiastic
with total precip amounts versus GFS deterministic and ensemble
mean. The EC ensemble means however are being skewed upward by
some fairly high amounts in some members. The most likely scenario
will see precip chances kick in late Tuesday night as the upper
trough is nearly over the area by that time. The best shot of lift
with this system will be at this time, however not the best time
for the best shot of moisture which arrives on Wednesday and
lingers through Thursday. This still is on track to be primarily a
south of Point Conception precip event, although areas north will
still have at least slight chances through Thursday. For now the
highest precip chances will be Wednesday night then tailing off
from there through Friday morning as the upper low should be far
enough off to our east by that time.
For amounts, nothing significant for storm totals is expected at
this time as EC/GFS ensemble means range from less than tenth for
the central coast, 0.1 to 0.5 inches SBA and VTU counties, and
0.25 to 0.75 inches around LA County, possibly a little higher.
There isn't a big orographic component with this, so not expecting
much if any precip enhancement for the mountains. In fact,
depending on the track of the upper low, there could even be some
low level easterlies on Thursday around its northern side across
LA/VTU counties, which would certainly hinder storm total
accumulations.
Temps will feel chilly over this period, especially on Wednesday,
and especially considering some places west of the mountains will
experience a 30 degree swing between highs on Sunday and highs on
Wednesday. For instance, downtown LA will likely have a high in
the low 90s on Sunday compared to a high in the low to mid 60s on
Wednesday.

.AVIATION...16/0550Z.
At 0545Z, the marine inversion at KLAX was based at 900 feet. The
top of the inversion was 1800 feet with a temperature of 17
degrees Celsius.
Overall, high confidence in 06Z TAF package. High confidence in
VFR conditions for most sites. Only exceptions will be KPRB where
there is high confidence in VLIFR conditions 11Z-16Z and KLGB
where there is high confidence in LIFR conditions 10Z-16Z, and a
20 percent chance of VLIFR conditions. Also increasing probability
of IFR cigs/vsbys at KLAX late tonight into early Saturday morning
per latest high resolution guidance.
KLAX...Moderate confidence in 06Z TAF. In evening update, leaning
towards IFR cigs/vsbys reaching KLAX late tonight into early
Saturday morning, but there is still a 40 percent chance of
no cigs developing.
KBUR...High confidence in 00Z TAF.
&&
.MARINE...15/806 PM.
For the Outer Waters, extended Small Craft Advisory (SCA) level
northwest winds through Saturday afternoon. For Sunday and
Monday, high confidence in winds and seas remaining below SCA
levels. On Tuesday and Wednesday, high confidence in SCA level
conditions developing due to increasing winds and a large
northwesterly swell. Additionally, there is a 30% chance of Gale
force gusts.
For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast. Winds and seas are expected to
remain below SCA levels through Monday. On Tuesday and Wednesday,
high confidence in SCA level conditions developing due to
increasing winds and a large northwesterly swell.
For the Inner Waters south of Point Conception, have removed
Small Craft advisory for tonight across the Santa Barbara Channel.
On Sunday, there is a 60% chance of SCA level northeast winds
from Ventura southward. On Monday and Tuesday, winds and seas are
generally expected to be below SCA levels although there is a 50%
chance of SCA level winds Tuesday afternoon and evening across the
western half of the Santa Barbara Channel. On Wednesday, moderate
confidence in SCA level winds developing across the entire
southern Inner Waters.
&&
.BEACHES...15/956 PM.
A strong area of low pressure across the Gulf of Alaska will
drive a moderately high northwest swell with a long period between
16-18 seconds through early Sunday morning. Surf is expected to
build to between 8-12 feet tonight and continue through much of
the weekend. A HIGH SURF ADVISORY is in effect through 10 AM
Sunday morning for the Central Coast.
A BEACH HAZARDS STATEMENT will be in effect for the beaches of
Ventura County and exposed west facing beaches across the Santa
Barbara South Coast from 10 PM PST tonight through 3 PM Sunday
afternoon.
With most of the swell energy from the Northwest, there will be
limited energy moving into the the Inner Waters south of Point
Conception. At this time, the main focus for elevated surf and
strong rip currents will be aimed for the exposed west facing
beaches of Ventura County and exposed west facing beaches across
the Santa Barbara South Coast. Elevated surf between 3-6 feet is
expected for these locations tonight through Sunday afternoon.
With high temperatures along the coast expected to be in the 80s
to lower 90s this weekend, local beaches will likely be busy this
weekend. The combination of elevated surf with long period swells
will bring the likelihood of dangerous RIP currents to these
locations. Surf is not expected to be as high across Los Angeles
County west facing beaches due to less swell energy.
&&
.FIRE WEATHER...15/957 PM.
A Fire Weather Watch is in effect for parts of Los Angeles and
Ventura Counties for later Saturday Night through Sunday.
On Saturday, northeast winds gusting to 20 to 40 mph will affect
the wind prone areas of all four counties. Minimum humidities
will lower into the 15 to 25 percent range, with a few lower
elevations of Los Angeles and Ventura Counties down to 10 percent.
Elevated to locally brief critical conditions are expected, but
staying under Red Flag Warning duration criteria.
Saturday night through Sunday, The Northeast winds will weaken some
over Santa Barbara and San Luis Obispo County, while strengthening
over Los Angeles and Ventura Counties with gusts in the 30 to 50 mph
range. Widespread minimum humidities will fall into the 8 to 15
percent range. This should result in critical Red Flag conditions
for the wind prone areas of Los Angeles and Ventura Counties late
Saturday night through Sunday afternoon. Sunday night through
Monday will remain warm and dry, but wind gusts will weaken
significantly to 15 to 30 mph and be confined to only the most
wind prone areas. Elevated conditions will continue, but Red Flag
conditions are not expected.
