area forecast discussion... Updated
national weather service los angeles oxnard ca
948 pm pst Sun dec 9 2018

Synopsis 09 640 pm.

There will be elevated winds, cooler temperatures, and a slight
chance of precipitation on the north slopes of the ventura and
los angeles county mountains Monday night and Tuesday. Another
slight chance of precipitation will develop across the region next
weekend. Otherwise dry and slightly warmer conditions will prevail.

Short term (sun-wed) 09 830 pm.

***update***
made a few tweaks to the temperatures for tonight and Monday, but
otherwise forecast is in good shape. Monday should be generally
similar to Sunday, except for the upper level clouds clearing out
by late afternoon or evening.

An upper level ridge of high pressure currently focused over
southeast california will continue to slide to the east through
Monday, while a weak upper level trough of low pressure pushes
through the state Monday through early Tuesday. There remains some
disagreement with the latest models as to if this trough will move
on through and into arizona on Tuesday (gfs), or dips to the
southwest off the southern california coast into Wednesday (ecmwf
and nam). With that said, there really isn't a whole lot of
difference between these solutions concerning the weather we
should expect for the next couple of days, except for whether or
not Wednesday will be warmer than Tuesday. The advisory-level
north winds are still on track for the wind prone areas. Tuesday
is still looking rain free, except for some north slope showers.

***from previous discussion***
partly cloudy skies as a whole should prevail Mon night with
clearing expected tue, except the N mtn slopes will have mostly
cloudy skies and a slight chance to chance of rain and snow
showers late Mon night into Tue morning. Skies are then expected
to be mostly clear across the region Tue night and wed.

In addition, gusty N winds will develop Mon night and persist
into tue, with the strongest winds likely from the sba county s
coast and mtns to the i-5 corridor in the l.A. Vtu county mtns. The
winds should also spread to the rest of the mtns and into some of
the adjacent vlys later Mon night thru Tue morning. It looks like
winds will be near advisory levels at times with wind gusts up to
35 to 45 mph. Wind advisories may be needed for this event
especially for the sba county S coast and mtns. Altho winds should
weaken some Tue night into Wed morning, there should still be
local N to NE gusts in the usual wind-prone areas.

Temps across the region are expected to have a cooling trend for tue,
with highs by Tue falling to a couple of degrees below normal for
many areas, then turn milder for wed. Temps in the warmest inland
coastal areas and vlys are forecast to be in the upper 60s to low
70s on mon, fall into the mid 60s to around 70 on tue, then warm
back to the upper 60s to lower 70s for wed.

Long term (thu-sun) 09 250 pm.

The ec and GFS are in good agreement thru thu, then differences show
up Fri thru sun. Upper level ridging will continue on thu. An upper
level trof moving thru the E pac will approach the ca coast on fri,
with the GFS weaker and ec stronger with this system, altho dry
weather should prevail thru Fri across SW ca.

The ec brings a front and fairly decent rain into the area fri
night and Sat morning while the GFS dissipates the front with dry
weather during the period except for a slight chance of showers
over far NW slo county Fri night. Decided to lean more toward the
gfs for this time frame.

The ec and GFS both agree to some extent on pushing another upper
level trof and surface frontal system into the area on sun, with
the ec faster than the GFS with this system. Also leaned more
toward the GFS with a slight chance to chance of rain moving
mainly into slo sba counties on sun.

There is really low to moderate confidence in the forecast for
the Fri night thru Sun timeframe given all the model differences
in speed and strength of the two weather systems. Additional model
runs will be needed to fine tune the pcpn fcst during the period.

The ec and GFS agree that there will be good offshore gradients
wed night into Thu with the potential for advisory level winds in
the usual offshore wind-prone areas of vtu l.A. Counties. Gusts up
to 35 to 45 mph will be possible.

Temps will be several degrees above normal for many of the coast and
vlys thu, then cool to slightly above normal fri. It looks like
temps will cool to near normal for the most part Sat and sun.

Aviation 10 0545z.

At 0510z over klax, there was no marine layer but there was a sfc
based inversion topping out at 500 feet with a temperature of 18
degrees c.

Good confidence in all tafs xcp ksmx and ksbp where where there is
a 30 percent chc of lifr conds 11z-17z.

Klax... High confidence inVFR conditions through Monday, and any
east winds staying under 6 kt.

Kbur... High confidence inVFR conditions through Monday with
light winds.

Marine 09 829 pm.

High confidence in winds staying below small craft advisory (sca)
through Monday morning, except for a 30 percent chance of sca
from point conception to san nicolas island later tonight. High
confidence in quickly increasing NW flow Monday afternoon through
Wednesday. Short period seas on top of a building long period nw
swell will accompany these winds for hazards sea conditions nearly
everywhere. SCA conditions are certain from the central coast to
san nicolas island, with a 40 percent chance for the western
portions of the santa barbara channel and santa monica basin in
the afternoon and evening hours.

Lox watches warnings advisories
Ca... High surf advisory in effect from 6 am Monday to noon pst
Tuesday for zones 34-35. (see laxcfwlox).

High surf advisory in effect from noon Monday to 6 pm pst
Tuesday for zone 40. (see laxcfwlox).

Pz... Small craft advisory in effect from noon Monday to 6 am pst

Hazard potential outlook (wed-sun)
Gusty advisory level north to northeast winds are expected
Wednesday night into Thursday. High surf and dangerous rip
currents are expected on the central coast Thursday through
Saturday, possibly expanding to most beaches on Saturday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
