Synopsis
Gusty northerly winds will continue through Friday for portions
of southwest california. High pressure aloft will gradually build
into the region through early next week. This combined with
offshore flow will support the warmest conditions this weekend
with cooling likely early next week as winds shift onshore.

Short term (tue-fri)
the windy week continues and will likely continue through at least
Friday. The winds have been generated by weather systems passing
to the north while a ridge of high pressure expands east across
the eastern pacific. This has created strong northwest flow aloft
and some of that has been transported to the surface. And we'll
see this pattern continuing off and on through Friday with
late Thursday night possibly being the strongest as another shot
of reinforcing northwest flow arrives.

On Wednesday the low lvl flow takes on a slightly more easterly
component as the lax-dag gradient briefly turns offshore behind
the system moving through tonight. This in combination with the
building ridge from the west will be enough to warm temps a few
more degrees, especially in the valleys where warmer areas will
climb well into the 80s. SRN sb county expected to warm up quite a
bit as well with the afternoon/evening sundowners and warmer air
at lower levels. Skies expected to be clear except for some high
clouds coming over the top of the ridge and some low clouds and
fog developing over interior slo county as the northeast flow
ushers in some moisture from the san joaquin valley.

A little cooling for coast/valleys mainly Thursday with weaker
offshore flow, then turning slightly warmer again Friday.

Long term (sat-tue)
models continue to suggest at least a moderate offshore gradient
Saturday as high pressure develops over the great basin behind an
upper low settling into new mexico. Although heights/thicknesses
not quite as high as with the warmup we saw late last week,
gradients are stronger. So for lower elevations temps should warm
up to similar levels, meaning high 80s to lower 90s for
la/ventura valleys and interior coastal areas. Not likely a
record setting event but still 15-20 degrees above normal. Would
like to see a little better support aloft for advisory level
northeast winds but gradients alone might be enough to generate
30-40 mph gusts in the favored areas.

Gradients quickly reverse Sunday so basically just a one day heat
event for coastal areas. Valleys will cool but still well into
the 80s. Then temps leveling off through early next week at near
to slightly above normal levels as onshore flow returns and quite
possibly some marine lyr clouds for portions of the coast.

Aviation 26/0000z...

at 1800z, the marine layer top was 1500 feet deep. The top of the
inversion was at 1700 feet with a temperature of 25 degrees
celcius.

High confidence in moderate to strong west to northwest winds
across the forecast area through the period... Shifting to the
north to northeast during the overnight to morning hours for the
l.A. Coast and valley site. Moderate confidence in wind strength
and direction as gusty winds shift between the directions
mentioned. Low level wind shear and turbulence are expected in
most locations.

Klax... Moderate confidence in the 00z taf.VFR conds expected but
wind speeds and direction are likely to be variable. There is a
10 percent chance of east winds greater than 8 knots early
Wednesday morning.

Kbur... Moderate confidence in the 00z taf. There is a 30% chance
of llws/turbulence through the period.

Marine 25/800 pm
for the outer waters, high confidence in current forecast. Strong
northwest winds are anticipated to continue through the week.

Currently, a gale warning is in effect through late Wednesday
night. There is a 70% chance that gale force winds will continue
through Friday and a gale watch is in effect from late Wednesday
night through Friday afternoon.

For the inner waters, moderate confidence in current forecast. A
gale warning is in effect through late tonight for the inner
waters south of point conception, mainly affecting the western
portions. Otherwise, strong small craft advisory (sca) level
winds are expected each afternoon/evening in zone 645 through
Friday with a 30% chance of gale force wind gusts developing. Due
to strong winds throughout the waters, seas will be very choppy
this week, making for hazardous boating conditions through the
week.

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.
