area forecast discussion... Updated
national weather service los angeles oxnard ca
930 pm pdt Tue jun 27 2017

Synopsis
High pressure aloft should weaken and onshore flow strengthen
into Thursday. Night through morning low clouds and fog will
spread into the coastal areas, possibly extending into some
valleys as early as Wednesday morning. A cooling trend will
continue with most areas falling to near-to-below normal, except
the desert. A weak low pressure system should arrive over the
weekend and into early next week and strengthen the onshore flow.

Short term (tue-fri)
a trough of low pressure moving over the pacific northwest this
evening will brush the area and weaken high pressure aloft through
Thursday. A cooling trend will continue into Thursday as onshore
flow strengthens. Low cloud coverage will scaled back some in the
current forecast as clouds are struggling to form south of point
conception with the eddy circulation slower to spin up. This may
affect temperatures somewhat for Wednesday and a few degrees may
be shaved off the valley temperatures.

An update will be issued shortly.

***from previous discussion***
we will get a brief ridge over the area Thursday into Friday that
will temporarily weaken the onshore flow and warm things up a few
degrees, but nothing close to what we had across the inland areas
over the the last week and especially Monday.

Another weak sundowner expected tonight across southern sb county.

Like the last few nights we'll see some local gusts to around 40
up in the foothill areas but overall a sub-advisory level event.

North winds will be weaker the next couple nights.

Long term (sat-tue)
the Thu Fri ridge will get knocked down by another pac NW trough
this weekend leading to a cooling trend and a deeper marine lyr.

Temps likely falling back down to normal levels. Low clouds will
clear off in most areas but could linger at the beaches well into
the afternoon. No major changes in this pattern through early next
week so look for minimal day to day changes in cloud coverage and
temps.

Aviation 26 0127z.

Moderate confidence in the current forecast. Lifr to ifr
conditions should spread in through 14z, then lift one category
between 10z and 14z. Highest confidence exists for the central
coast terminals. There is a chance that ifr to MVFR conditions
could linger at coastal terminals into Wednesday afternoon.

Klax... There is a 80 percent chance of ifr conditions between 08z
and 16z. Conditions should improve to MVFR orVFR between 14z and
18z. There is a 20 percent chance that ifr to MVFR conditions
could linger until around 20z.

Kbur... There is a 50 percent chance of ifr conditions between 11z
and 16z. Otherwise,VFR conditions are expected throughout the
period.

Marine 27 800 pm.

High confidence in small craft advisory (sca) conditions from the
central coast to san nicolas island through at least Friday, and
likely through Saturday. The current SCA will be extended each
day. High confidence in SCA conditions over the santa barbara
channel this evening then diminishing through late tonight. There
will be lulls each morning within 10 miles of the coast.

Two distinct wave types will be observable over the waters, and a
short period (6-8 second) west swell and or wind wave. The buoys
will likely highlight the long period swell at times, but the
short period swell will be most noticeable and will be highlighted
in the forecast. By the middle to end of the week, the short-
period west swell will dominate as the south swell fades.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 3 am pdt Wednesday for
zones 645-650. (see laxmwwlox).

Small craft advisory in effect until 6 am pdt Thursday for
zones 670-673-676. (see laxmwwlox).

Hazard potential outlook (fri-tue)
no significant hazards expected.

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.
