area forecast discussion... Updated
national weather service los angeles/oxnard ca
854 pm pdt Tue mar 28 2017

Synopsis
High pressure and weakening offshore flow will bring a warming
trend to the area through Wednesday. A trough of low pressure
will bring cooler conditions by Friday with another round of
strong and gusty northerly winds. Warmer conditions will likely
return this weekend as high pressure and weak offshore flow
persists.

Short term (tue-fri)
high pressure aloft over the west coast will continue to build
over the region into Wednesday. Offshore flow at the surface will
continue across the area. A warming trend will persist into
Wednesday. A tightening northerly surface pressure gradients is
bringing some gusty winds to the interstate 5 corridor and across
southern santa barbara county. Klax-kbfl and ksba-kbfl surface
gradients are hovering around -6 mb this evening. A wind advisory
continues for southern santa barbara county tonight but was
expanded to the los angeles and ventura county mountains tonight
through Wednesday.

The northerly gradient will turn northeasterly into Wednesday
morning, continuing gusty north to northeast winds across the los
angeles and ventura county mountains, and pushing some gusty santa
ana winds into the ventura, san fernando, and santa clarita
valleys, as well as the santa monica mountains. If model solutions
and gradient trends mesh, the klax-kdag surface pressure gradient
could exceed -5 mb by late tonight and early Wednesday morning. A
wind advisory has been issued as winds will increase over the
next several hours to near advisory strength. 850 mb winds
increase to around 40 knots across los angeles county and 950 mb
winds to around 25-35 knots along the los angeles-ventura county
border.

Temperatures will likely be warmed a tad for Wednesday in the
latest update to the package.

*** from previous discussion ***
on Thursday a trough will move into NRN california then move
southeast into southern nevada Thursday evening. This will result
in a rapid shift from offshore to onshore (an almost 7 mb 24 hour
trend from Wed from lax-dag), and several degrees of cooling,
especially for coast/valleys.

Another round of very gusty north winds expected behind the
trough Thu evening into Friday morning with speeds possibly
approaching the levels experienced last night.

Then gradients turn offshore again Friday, though air mass will be
quite a bit cooler so highs should be a few degrees cooler than
thu despite the offshore trends.

Long term (sat-tue)
a second day of offshore gradients Saturday will be accompanied
by a much warmer air mass as the upper low exits to the east and
the ridge builds. Highs not expected to be quite as warm Saturday
as tomorrow but still at least 10-15 degrees above normal. There
will be some northeast breezes but likely below advisory levels.

Gradients then shift to onshore Sunday that should lead to some
cooling but still at least a few degrees above normal in most
areas.

For Monday and Tuesday the GFS has shifted towards the much
weaker and progressive trough pattern that the ECMWF has been
advertising. It's been bouncing around quite a bit though so
confidence is pretty low for early next week, but if these trends
hold then it would certainly be a warmer and less windy forecast
than previously expected with no chance of rain. Bumped up highs
a few degrees but didn't want to adjust too much in case the
solutions reverts back to a cooler/windier one.

Aviation 29/0045z.

At 00z, there was no marine layer at klax.

High confidence in the current forecast.VFR conditions are
expected throughout the period, except for a chance of lifr
conditions at kprb between 13z and 17z. Periods of moderate low-
level wind shear and turbulence are possible through 16z.

Klax...VFR conditions are expected throughout the period. There is
a chance of northerly cross winds between 10 and 20 knots between
02z and 08z. Any east winds developing after 08z should remain
less than 7 knots.

Kbur...VFR conditions are expected throughout the period. Periods
of moderate low-level wind shear and turbulence are possible
between 07z and 11z.

Marine 28/800 pm.

Across the outer waters... Another gale warning continues as model
solutions project 35 kt gusts through much of tonight. Small
craft advisory winds will resume Wednesday and continue into
Wednesday night. By late Thursday, wind speeds in the outer waters
may again increase to gale warning criteria.

Across the inner waters... A SCA for hazardous seas is in effect
n of point conception through Wednesday morning. Gale level winds
may affect the inner waters on Thursday and Friday.

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.
