Synopsis
A ridge of high pressure building into the region and weak
offshore flow will likely bring record heat to portions of
southwest california sometime Tuesday through thanksgiving day.

The ridge will gradually break down as a trough of low pressure
approaches the west coast, supporting a cooling trend heading into
this weekend.

Short term (tdy-wed)
plenty of high level clouds were moving into the forecast area this
morning, with some mid level clouds also noted N of point
conception. Filtered sunshine thru the high clouds will prevail
today over much of the area, altho for slo sba counties, mostly
cloudy skies at times cannot be ruled out. Fairly decent offshore
gradients this morning (e.G., at 16z -2.0 mb lax-dag, -2.8 mb lax-
bfl, and -3.6 mb sba-bfl) was supporting locally gusty N winds over
the santa ynez mtns and l.A. County mtns. The winds are expected to
continue into the afternoon, and may expand some over these areas,
with gusty NW winds possible along the i-5 corridor by late today.

Temps are forecast to be a bit warmer today and several degrees
above normal, with highs in the warmest vlys and inland coastal
areas expected to top out in the mid 70s to low 80s.

Generally flat and dirty upper level ridging over the forecast area
today, with 500 mb heights around 582-584 dm, will gradually build
tonight thru wed. By Wed afternoon, 500 mb heights will increase to
590-592 dm across the region.

The mid and hi level moisture over the region will linger into
tonight then clear out by early Tue for mostly clear skies tue
thru wed.

Northerly gradients will increase some thru tonight which will
support gusty N canyon winds for the sba county S coast and mtns,
with some gusts to advisory levels possible. Gusty NW winds can also
be expected in the l.A. Vtu mtns along the i-5 corridor this
evening, then transition to N to NE and expand S into the favored
foothills and vlys of vtu l.A. Counties later tonight into tue
morning. Locally gusty NE winds will be possible over these areas of
vtu l.A. Counties again Tue night into Wed morning. Otherwise, there
will generally be weak offshore low level flow over swrn ca
tonight thru wed, especially during the night and morning hours.

The rising 500 mb heights, warming boundary layer and 950 mb temps,
and offshore flow, will all help to bring much warmer than normal
temps to the forecast area Tue and wed. Near record to record high
temps will be possible for several climate stations, with temps on
wed increasing to 15 to 20 deg above normal for many areas. Temps in
the warmest vlys and inland coastal areas should reach the mid 80s
to low 90s on tue, and low to mid 90s on wed. Even overnight temps
should be very mild in the breezy foothill and lower mtns Tue night
and Wed night where lows in the low to mid 70s will be possible.

***from previous discussion***

Long term (thu-sun)
the upper high will begin to be forced eastward on thanksgiving
day as a large trough moves into the eastern pacific. However,
latest computer models show the upper high remaining firmly
entrenched across the region through Thu morning, and low level
gradients remaining offshore. While there may be a few degrees of
cooling, especially near the coast, it will likely be another very
warm to hot day in most coastal and valley areas thu, after a
warm Wed night. MAX temps could still reach or exceed 90 degrees
on thu, possibly even across interior sections of the coastal plain.

The highest temperature ever recorded at downtown los angeles on
thanksgiving day since 1877 (on which the date varies from year to
year of course) was 90 degrees on november 26th, 1903. This record
has the potential to be tied or broken this upcoming thanksgiving
day.

The upper high will continue to be suppressed southward and will
weaken on Fri as a large trough slowly approaches the west coast.

There will be several degrees of cooling across the entire
region on fri, but still, temps will be at least 10 degrees above
normal in many areas. The cooling trend is expected to continue
through the weekend as heights gradually fall and onshore flow
increases, but temps will likely remain a bit above normal even
through Sunday. Any rain with the approaching trough is likely to
stay to the north of the region.

Aviation 20 1000z...

at 1000z, there was neither any marine layer or marine inversion
at klax.

Overall, high confidence in 12z TAF package as weak offshore flow
will keep all sitesVFR through the period.

Klax... High confidence in 12z taf.

Kbur... High confidence in 12z taf.

Marine 20 900 am...

for the outer waters, moderate confidence in current forecast.

are only expected to gust to about 25 knots through 05z this
evening. Winds will stay below SCA speeds Tuesday and Wednesday.

For Thursday and Friday, SCA level winds are likely.

For the inner waters, good confidence in current forecast. For the
waters north of point sal, winds and seas are expected to remain
below SCA levels through Friday. For the waters south of point
conception, winds and seas are expected to remain below SCA levels
through Friday.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 9 pm pst this evening
for zones 673-676. (see laxmwwlox).

Hazard potential outlook (wed-sun)

with warm and dry conditions Wednesday night. There will be
gusty winds at times across portions of los angeles and ventura
counties. There will likely be elevated fire danger across
portions of los angeles and ventura counties during this time.

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.
