Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1022 AM PST Mon Dec 30 2024
.SYNOPSIS...30/230 AM.
An extended period of gusty north to northeast winds is expected
through through the end of the week. A warming trend will start
today and continue through the rest of the next week especially
mid week when the Santa Ana winds arrive and high pressure builds
over the area.
&&
.SHORT TERM (TDY-WED)...30/850 AM.
***UPDATE***
Latest satellite/surface observations indicate some low clouds and
patchy dense fog across the coastal plain and valleys south of
Point Conception and across interior sections with mostly clear
skies elsewhere. Current wind observations indicate northerly
gusts generally in the 30-45 MPH range across the usual northerly
wind-prone areas.
Forecast-wise for the immediate short term, no significant issues
are expected. Northerly winds are expected to gradually diminish
into this afternoon. So, will likely let the current slate of WIND
ADVISORIES expire at 1000 AM this morning. By this evening, there
is the potential for the northerly winds to begin to "ramp up"
again. So, will need to watch for the potential for additional
advisories. As for low clouds and fog, will expect everything to
clear by late this morning or early this afternoon.
Overall, current forecast has good handle on the immediate short
term. Will make minor tweaks to the sky forecast, based on
satellite trends, and update forecast for advisory expiration. For
the afternoon forecast suite, main focus will be on weak to
moderate Santa Ana winds Tuesday through Thursday.
***From Previous Discussion***
An eddy spun up last evening and created a blanket of stratus that
covered the LA/VTA csts and most of the vlys. A 3 mb offshore push
from the north has produced some canyon winds through the Santa
Monicas and this is clearing portions of the LA cst. The offshore
push will create eratic clearing this morning but most areas
should be sunny by late morning. The barest of front passed over
the northern portion of the forecast area last night and while
rainfall amounts were negligible or nonexistent (and confined to
the Central Coast). It did usher in enough cold air advection
that, when combined with the offshore flow from the north, to
produce low end advisory winds through the mtns and SBA south
coast. These winds will diminish later this morning. The offshore
flow will bring 3 to 6 locally 8 degrees of warming to the csts
and vlys (the SBA south cst will be the exception where the lack
of northerly winds in the afternoon will bring 5 to 10 degrees of
cooling). Cool air advection from the north will cool the mtns and
interior by about 10 degrees.
A little dry trof will ripple over the state tonight. It will do
little except to increase both the mid level clouds and the
offshore flow from the north. At the same time building high
pressure in the Great Basin will bring offshore flow from the
east. An eddy will develop first and low clouds are forecast to
overspread the LA/VTA csts/vlys, although there is a chc (40%)
that the offshore flow will keep them away. Advisory level gusts
from the north will develop in the mtns in the wake of the trof.
As the offshore push for the east increases Tuesday morning the
winds will shift from the N to NE. Advisory level gusts will
likely continue in the mtns but right now there is only a 40
percent chc that advisory gusts will develop across the wind
prone csts and vlys. Skies will turn sunny in the afternoon and
max temps will bump up a couple of degrees across most of the
area.
The offshore flow will peak on Wednesday. Low end advisories look
likely for the Santa Ana wind corridor (about 10 miles either side
of a Santa Clarita to Pt Mugu line). The bigger news for New Years
Day will be the picture postcard weather with sunny skies and
temperatures in the 70s (up 5 to 10 degrees from Tuesday and about
8 degrees over normal).
.LONG TERM (THU-SUN)...30/318 AM.
EC and GFS agree that on Thursday there will be a ridge overhead
with 578 dam hgts. There will be 2 to 4 mb of offshore flow from
both the E and N. 40 percent of the ensembles show that this will
be strongest Santa Ana day but more likely it will come in weaker.
Another 1 to 2 degrees of warming will make this the warmest day
of the week for the csts/vlys with plenty of 70s and even some
lower 80s.
The ridging will continue on Friday and this will continue the
warming trend for the interior (aided but less cool air coming in
from the high desert) The onshore flow will be much weaker and
likely onshore to the E. This change in the sfc flow pattern will
cool the csts/vlys by about 5 degrees. Despite the cooling max
temps will remain above normal.
Another weak trof will pass over the northern 2/3rds of the state
early Saturday. There is a chc of some light rain for SLO county
but other wise it will just bring some clouds and 3 to 6 degrees
of cooling.
Not much to say about next Sunday. It will be dry and coastal
temps will be a little below normal while further inland it will
be several degrees above normal.
A peak at the full 15 day runs of the EC and GFS show no
appreciable chc of rain.

.AVIATION...30/1821Z.
At 17Z at KLAX, the marine layer was around 1100 ft deep. The top
of the inversion was at 4400 ft with a temperature of 19 C.
Overall, moderate confidence in 18Z TAF Package. Highest
confidence in KPRB, KSBP, KSMX, and desert sites (KPMD, KWJF).
Wind gusts could be off 5 kts at times.
Low confidence in remaining TAFs. Timing of cigs/vsby restrictions
may be off +/- 3 hours. Flight cats could be off one or two,
especially during worst conditions.
KLAX...Low confidence in 18Z TAF. There is a 30-40% chance of
1/2-3/4SM and 372-374-375-379. (See LAXRFWLOX).
