Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
427 AM PST Thu Dec 26 2019
.SYNOPSIS...25/611 PM.
A cold storm system will continue to bring rain, snow, and strong
winds across the region through Thursday. The heaviest rain and
snow will fall tonight to Thursday morning, and snow is expected
in the Antelope and Cuyama Valleys. Conditions will clear on
Friday and temperatures will be near normal by the weekend.
&&
.SHORT TERM (TDY-SAT)...26/425 AM.
The storm has largely lived up to expectations. It was a little
more convective than thought and moved a little faster as well.
Still rain and snow totals were pretty much where they were
supposed to be.
The upper low is just to the west of the channel islands and in a
somewhat rare event the sfc low is right under the upper low (most
of the time the upper low is over Oregon or Nrn CA) The cold core
of the upper low will destabilize the atmosphere and allow for a
showery regime to set up later this morning and then persist into
the afternoon. The atmosphere will be unstable enough to warrant
a slight chc of TSTMs as well.
Winter Storm Warnings are working out well in the mtns were at
least a foot of snow has fallen above 5000 feet with more falling
now. The foothills of the Antelope Vly have already had the rain
turn to snow. Once the winds turn to the east later this morning
the cool air advection off of the interior deserts will lower the
snow level to the vly floor. The system is moving a little faster
than forecast and there is a chc that the Winter Weather will end
sooner than 1000 pm tonight.
The sfc low will move to the south and east of the area later
today. The wrap around flow from this low will switch the winds
from a southerly direction to a northeast direction. This wrap
around flow will keep upslope flow going in the Antelope Vly and
the snow event there could persist into Friday morning.
Wind advisories may be a little overdone and these will be
evaluated using the 12Z mdl runs and mid morning wind
observations.
SLO/SBA/VTA counties will, in general, only see a tenth to a third
of an inch of additional rain today. The rainfall amounts will be
very variable due to the showery nature of the system. The steady
rain over LA county this morning plus additional rain from the
afternoon shower activity should add up to about a half inch to an
inch. The greatest amount of rain will fall over the San Gabriel
vly and the eastern San Gabriels.
Rainfall rates will not diminish and will range from a quartet
inch per hour to .75 inches per hour with inch per hour rates
possible under heavy showers or TSTMs.
High pressure and easterly flow will set up Friday. It will be dry
and skies will be at worst partly cloudy. The NE winds may reach
advisory levels in the mtns and Santa Clarita Vly in the morning.
Max temps will rise into the lower 60s across the coasts and vlys.
The high pressure will continue Saturday. It will be less breezy
but it will not warm up any and max temps will remain below
normal. The dry air and cool air mass will combine to make wake up
temps rather cool and there will likely be some freezing temps in
the vlys.
.LONG TERM (SUN-WED)...26/424 AM.
The ridge will persist into Sunday afternoon. The day will start
out sunny but the clouds will begin to move in from the NW moving
to the SW. Hgts remain low and max temps will remain 4 to 8
degrees below normal.
Both the EC and the GFS move an upper low down and into the state
Sunday night into Monday morning. There are significant and
important differences in the mdls.The EC takes an inside (drier
track) while the GFS takes an western over water (wetter track).
The GFS brings decent rain overnight to the area while the EC
has much less. The ensembles have not been much help with all
members tracking closer to their respective deterministic
solutions.
Monday's forecast is not settled at all. The GFS brings a moderate
storm to the area with up to an inch of rain. The EC bring much
much less precip and even that is mostly over the mtns. EC has
been the long range mdl of choice of late so forecast is biased in
that direction but still this is the area of future forecast
focus.
The GFS has some rain lingering into Tuesday morning over LA
county while the EC is dry. Both mdls forecast a little offshore
flow but nothing too strong. All mdls show dry conditions for the
afternoon and evening. Max temps will continue to run in the low
to mid 60s across the coasts and vlys.
New Year's Day most likely will be dry as both the EC and GFS have
different but dry flow patterns. The EC has higher hgts and its
solution would be a few degrees warmer. Both mdls show a little
offshore flow but it is weaker than Tuesdays.

&&
.BEACHES...26/142 AM.
A relatively large northwest swell will continue to bring high
surf to the Central Coast today and continue through Friday
evening. High surf between 10 and 14 feet with local max sets to
16 feet across northwest to west facing beaches can be expected.
The highest surf will peak mid-morning today through early Friday
morning. High tide of around 6.8 feet will occur around 9 AM
this morning.
There is an increased risk for ocean drowning. Rip currents can
pull swimmers and surfers out to sea. Large breaking waves can
cause injury, wash people off beaches and rocks, and capsize small
boats near shore. Given the surf conditions, there will continue
to be a high risk of dangerous rip currents and breaking waves for
all local beaches.
Some swell energy will refract into the Southern California Bight
allowing for elevated surf 3 to 6 feet with local sets to 7 feet
across exposed west facing beaches from Santa Barbara to Los
Angeles Counties by this morning and continue into Friday. Given
the surf conditions, there will be a high risk of dangerous rip
currents within the surf zone.
