Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
Issued by National Weather Service San Francisco CA
1114 AM PDT Tue Mar 31 2020

.SYNOPSIS...31/106 AM.

Conditions will be warm and dry through Saturday then there is a
slight chance of rain across the region late Sunday through early
Tuesday. Temperatures will be cooler as the weak storm moves
through but any snow will be well above the major passes.

&&

.SHORT TERM (TDY-THU)...31/938 AM.

Morning satellite imagery reveals filtered sunshine covering most of
the region as widespread high clouds fill in from the SW. These high
clouds are associated weak upper level low approaching far Southern
California/Northern Baja.  Additionally, patchy fog is also showing
up in the Southern Salinas Valley and Paso Robles region.  The Paso
Robles Airport had reported dense earlier this morning, but latest
observations shows rapid improvement. The fog will likely dissipate
by 10 AM at the latest. The bigger weather impact today will be
gusty offshore flow for southern SB County and the I5 Corridor later
this afternoon.  This will likely be a short fused wind event and
will require a low end wind advisory to be issued.  Per hi-res
models and gradient strength wind gusts of 40 to 50 mph will be
possible.  Current thinking is wind advisory this afternoon through
the middle of the night.

***From Previous Discussion***

Dry NW flow over the area. Some high clouds are spilling off of a
weak disturbance to the SW and this will make skies partly cloudy
today. There will be weak offshore flow this morning both from
the east and north and this along will 578 DM hgts will make it
the warmest day of the next 7. Almost all non mountain temps will
be in the 70s and would not be surprised if a location or two hit
80 today.

A barely perceptible disturbance will move over the area this
afternoon. It will do nothing except to increase the NW to N winds
across the area. Gusty winds will develop across the SBA south
coast (esp the Gaviota area), the I-5 corridor and the NW portion
of the Antelope Vly. Some low end advisories may be needed in
these areas. The eddy will be a little stronger and there will
likely bring some stratus to the LA coast and San Gabriel Vly.

Not much change on Wednesday. Skies will be sunny save for the
patches of morning low clouds. Max temps will fall 2 to 4 degrees
as the hgts fall and may fall even more if the hgt falls come a
little sooner than fcst.

Still gusty but slightly weaker winds again on tap for Wednesday
night as the northerly grads relax some. A better eddy will bring
more in the way of low clouds to the LA cst and lower vlys and
perhaps into the VTA coast as well.

Not expecting much in the way of clouds on Thursday but a little
trof will ripple over the state and usher in a little more cool
air. Expect max temps to drop a few more degrees and end up 3 to 6
degrees blo normal.

.LONG TERM (FRI-MON)...31/312 AM.

Hgts rise just a touch on Friday and max temps will nose up 1 to 2
degrees under mostly clear skies.

The EC and the GFS are not in the best of agreement on Saturday
but both mdls have some sort of trof moving through the north of
the state something late morning through early evening. All and
all not the greatest of effects on the days weather. Skies will
probably turn partly cloudy and max temps will sag down 2 to 4
degrees maybe a little more or maybe a little less depending on
the onset of the lower hgts. The faster GFS would lead to a cooler
day.

The EC and the GFS are struggling to figure out to handle the
track of a cold upper low rotating out of BC. There has been
little in the way of agreement between the mdls or from run to
run. The ensembles, as is ofter the case when operational mdls
are confused, have a much larger than normal solution spread.

The EC is the wetter of the two mdls but the GFS has trended
toward the EC soln. Pretty sure every area will see some rain
during the 48 hour period just not sure how much or exactly when.
For now will broad brush in clouds and chc pops and wait for the
mdls to converge on a solution.

Cooler for sure with max temps around 10 degrees blo normal.
