Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
158 PM PST Wed Dec 12 2018

.SYNOPSIS...12/1239 PM.

A ridge of high pressure will warm temperatures and bring
offshore winds on Thursday over Los Angeles and Ventura counties.
A low pressure to the north will pass through Friday to bring
cloudy skies and cooler temperatures to most areas. The next
possibility for rain may come late into the weekend.

&&

.SHORT TERM (TDY-SAT)...12/145 PM.

Offshore gradients were a little weaker today and this lead to a
cooler day for coast and valleys. Had some marine layer stratus
this morning south of SB County and some patches linger over the
coastal waters and srn LA County. However, a strong offshore trend
will develop this evening as high pressure strengthens over the
Great Basin following the passage of a low pressure system into
New Mexico. Model forecast gradients have dropped slightly from
earlier runs but still pretty healthy at -6.5mb LAX-DAG. The
primary limiting factor though is the absence of support aloft as
a strong upper level ridge will move in over California. So no
thermal support and minimal wind support aloft. Gradient driven
events often struggle to meet advisory criteria and if they do
it's low end and isolated so for now am opting to keep most areas
below advisory levels. Eastern Ventura County valleys and the
Santa Clarita Valley will have the best chance of reaching
criteria but even there it will likely be very low end with gusts
to around 35 mph.

The downsloping winds will help temps warm up several degrees from
today, especially at the coast, with highs in the 70s most lower
elevation locations.

Offshore gradients weaken quite a bit Friday as the ridge quickly
exits and the next trough arrives along the west coast. Onshore
trends along with what is expected to be a thick high cloud
shield will knock a few degrees of Thursday's temps, especially
coast/valleys.

The tail end of a weakening cold front will move through Friday
night. Models have been going back and forth on whether there will
be enough left of the front to drop rain across the Central Coast.
The operational GFS and ECMWF models wash out the front before
landfall but the NAM and several of the GEFS members do show some
very light precip at least clipping the northwest section of SLO
County so will keep some low chances there. Otherwise, very little
impact with skies clearing Saturday. Temps on the cool side still
with highs in the 60s most lower elevation locations.

.LONG TERM (SUN-WED)...12/155 PM.

Sunday will almost be an exact duplicate of Saturday except for
an increase in high clouds through the afternoon ahead of the next
system for Sunday night and Monday. This one has a little more
staying power as the upper level trough is deeper and colder with
more energy than the previous system. This should easily hold
together well enough to bring rain to areas north of Pt
Conception, albeit pretty light. Not quite as confident in the
south because the ECMWF really weakens the front after it moves
around Pt Conception. The GEFS ensembles are mixed on the idea as
well so will go with relatively high pops up north but only 30-50
in the south for now until models can get a better handle on it.
It's a low impact system either way as rain amounts are not
expected to exceed a half inch and rates won't come close to
posing issues for burn areas. Maybe some light snow accumulations
in the mountains.

Then turning sunny again Tue/Wed with increasing offshore flow. An
upper ridge builds in pretty fast so temps will be warming up
quickly especially with the offshore flow. By Wed we should be
well up into the 70s and possibly even some lower 80s by Thu if
forecast gradients stay about where they are or get stronger.
Could be a low end advisory level Santa Ana event Tue/Wed. Dry and
warm weather expected to last through the end of next week.
