Synopsis 25 1148 am.

A trough of low pressure will approach the west coast through
Friday before settling over the region through early next week.

This will result in a gradual cooling trend with increasing night
to morning low clouds through Friday. It will be breezy at times
in the evening to overnight hours and near normal temperatures
will continue through the weekend.

Short term (tdy-sat) 25 1214 pm.

Southwest flow aloft and increasing onshore flow are the themes
for the next few days as a large low pressure trough dominates
across the eastern pacific ocean. This pattern will result in a
deeper marine layer through Saturday with locally gusty southwest
winds through the highway 14 corridor of the san gabriels and into
the antelope valley. Pressure gradients increase 2-3 mb over today
and reach a peak of 9.5 mb between lax-dag on Thursday afternoon.

Wrf high-res model data also shows sustained winds over 25kts so
would expect a wind advisory will be needed for the av for the
afternoon and evening time frame.

There will be weak north winds for the western canyons of the
south santa barbara coast this evening. This may be just enough to
kick stratus southward off the coast by Thursday morning, and
models support this idea. Elsewhere, the low clouds and patchy fog
may gray pattern will persist overnight and through the morning
hours through Saturday. Temperatures will remain rather cool near
the beaches and normal for inland valleys and mountains. Stronger
onshore flow tomorrow will result in gusty west winds for the
central coast in the afternoon. Then, we will see sundowner season
get fully underway both Thursday and Friday evenings as north
winds kick in for passes and canyons west of santa barbara.

Advisory level winds look likely to occur with the sba-smx
pressure gradient peaking between 4-5mb late Friday and again late
Saturday.

Long term (sun-wed) 25 1228 pm.

Confidence in the longer term forecast is moderate. The eastern
pacific low pressure trough moves inland across northern
california and oregon over the weekend, then carves a trough
throughout the great basin early next week. This brings a more
northerly wind pattern into southwest california with periods of
gusty north-northwest winds across the region. Depending on the
location of the trough and or low pressure systems we could see
some light showers in the mountains early in the week, but this
scenario is an outlier and chances will remain under 15 percent.

The ECMWF and to a lesser degree on the gfs, high pressure will
build into the west coast by mid-week with temperatures rebounding
on Wednesday with the start of a warming trend and weak offshore
flow for the later part of the week.

Aviation 25 1930z.

At 1730z at klax, the marine layer was near 1500 feet deep. The
top of the inversion was near 2600 feet with a temperature around
18 c.

Moderate confidence in 18z tafs. MVFR CIGS toVFR transitions
could be off by + - 1 hour. Good confidence in tafs 20z-04z. Then
moderate confidence with persistent pattern once again tonight
into Thursday morning. 40% chance that ifr MVFR CIGS could linger
an additional compared to today.

Klax... Moderate confidence in 18z taf. Expect a persistent
pattern with a 30% chance for MVFR CIGS lingering an extra hour or
so.

Kbur... Moderate confidence in 18z taf. Will continue with a
persistent pattern. Ifr conds expected between 10z to 16z. A 30%
chance that CIGS could develop an hour earlier and scour out an
hour later.

Marine 25 1143 am.

High confidence in winds and seas remaining below small craft
advisory levels across the waters through Thursday morning. Winds
will likely increase across the outer waters Thursday afternoon
through much of the following week. A gale watch has been issued
for the two southern outer water zones starting Friday afternoon
and continuing through early Monday afternoon. There is a 50%
chance gale force winds will continue across the same area into
early next week. NW winds will continue to be gusty across the
northern outer waters zone but should remain below gale levels.

There is a 70% chance that small craft advisory (sca) gusts will
occur during the the same time period as the gale watch and into
early next week. Expect building short period seas during this
time as well that will translate into the inner waters.

Inner waters for areas S of point conception... Waters should be
mostly quiet through Friday morning, then strong SCA level gusts
and a 40% chance that gale force winds could affect the western
portion of the eastern sba channel Friday afternoon and evening.

Gusty NW winds will become more widespread across the entire inner
waters Saturday. 70% chance for SCA winds and 30% chance for gale
force winds western portion of eastern sba channel in the
afternoon.There will be a 40% chance for SCA across the inner
waters from point sal north on Friday, and 70% chance for
Saturday. Winds should taper off a bit Sunday for all inner water
locations with a 30% chance for a sca.

Lox watches warnings advisories
Ca... None.

Pz... Gale watch in effect from Friday afternoon through late
Sunday night for zones 673-676. (see laxmwwlox).

Hazard potential outlook (sat-wed)
There will be potential gale force winds mainly for the outer
coastal waters during the outlook period.

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.
