Synopsis 20 225 am.

A deep marine layer and strong onshore flow will bring a cooling
trend through Friday. For the coast and valleys, low clouds with
possible night through morning drizzle will likely struggle to
clear each afternoon through Friday. A warming trend is expected
over the weekend and into early next week away from the coast as
onshore flow weakens.

Short term (tdy-sat) 20 301 am.

Strong onshore flow in place across the region this morning
continues to strengthen as a trough of low pressure over the
pacific northwest digs south. Klax-kdag surface pressure gradients
sit near 8 mb onshore with a 2.5 mb onshore trend. The latest fog
product shows marine layer induced stratus well entrenched this
morning and expanding well into the valley areas. The latest amdar
soundings from klax indicate a marine layer depth near 2000 feet
deep, a tad lower than what nam-wrf time height sections indicate.

As weak ridging clears out of the area near daybreak, the marine
layer depth should start to deepen to near 3000 feet deep, and the
stratus should expand into the coastal slopes of the mountains.

With some weak omega values in the marine layer depth, patchy
drizzle cannot be ruled out this morning across the area.

The trough of low pressure, centered over the washington state
will dig south into the great basin through Friday. This trough
will brush the area and strengthening onshore flow should deepen
the marine layer to between 3500 and 4500 feet across the area.

Instability with the trough will bring the possibility for night
through morning drizzle tonight through Friday. Drizzle could turn
heavy tonight across the southern portion, and possibly become
light rain across the los angeles basin tonight. Pops have been
tweaked, but slight chance to chance pops remain for the los
angeles basin tonight and into Friday morning. Low clouds will
likely struggle to clear each day out of the coast and valleys
through Friday. Clouds will likely hug the coast, setting up a
typical gloomy day for june.

With strong onshore pressure gradients, gusty south to southwest
winds are likely across the interior portions of the area. A wind
advisory remains in effect for the antelope valley, but the timing
was adjusted earlier to start late this morning. Local advisory
level winds in the foothills already this morning will become more
widespread as the morning progresses. The wind advisory was also
expanded to include the san luis obispo county interior valleys
for this afternoon and evening. Guidance for kprb is impressive,
with model guidance suggesting 26-30 knots this afternoon.

Strong onshore flow will remain into Friday night and Saturday
morning, but gradients will start to weaken. A deep marine layer
should remain in place into Friday night, then start to thin
overnight into Saturday. Clouds will likely to struggle to clear
at the beaches each afternoon and evening. A warming trend will
develop away from the coast as onshore flow weakens with the
trough pulling away from the region. Better clearing should occur
for the valley areas.

Long term (sun-wed) 20 313 am.

500 mb heights climb and 1000-500 mb thickness values deepen
through Monday. A warming trend will continue into early next week
as weak ridging over the pacific ocean noses into the state. An
onshore flow pattern will continue across the region and keep a
persistent marine layer in place. With 1000-500 mb thickness
values increasing, the marine inversion should strengthen and keep
a june gloom pattern in place at the beaches.

A trough of low pressure south of the aleutian islands this
morning will lift out over the pacific high pressure system, then
dig into the pacific northwest for Tuesday and Wednesday. Model
solutions agree with the trough positioning and timing reasonably
well. A cooling trend is possible for the middle portion of next
week, but it should not be as cool away from the coast as models
do agree with a high pressure system expanding across the desert
southwest and sonoran desert.

Aviation 20 1231z.

At 1132z, the marine layer depth was around 2600 feet deep at
klax. The top of the inversion was near 4600 feet with a
temperature around 18 degrees celsius.

N of point conception... Moderate confidence with 12z tafs. 30%
chance for MVFR CIGS to occur + - 1 hour from taf. Good confidence
for MVFR tafs after 16z this morning. Expect a persistent pattern.

There is a 30% chance that coastal CIGS could scour out after 20z.

Low clouds ifr MVFR will resurge inland once again early this
evening.

S of point conception... Moderate confidence with 12z tafs. Expect
MVFR CIGS to persist across coastal TAF sites through the
afternoon. There is a 20% chance that CIGS could scour out along
coastal tafs before 21z. Good confidence for timing of stratus to
scour out across coastal valleys. Expect an earlier surge of
stratus this evening around 03z. Give or take an hour.

High confidence for gusty SW winds across the antelope valley this
afternoon through late this tonight.

Klax... Moderate confidence with 12z taf. Expect persistent MVFR
cigs to linger through the afternoon hours. There is a 20% for
cigs to scour out before 20z.

Kbur... Moderate confidence in 12z taf. Expect high ifr cigs
through 14-15z then becoming MVFR. There is a 30% chance that cigs
could linger up to a couple hours longer than TAF suggests.

Ifr MVFR CIGS will redevelop after 03z.

Marine 20 127 am.

Outer waters... High confidence with seas remaining below small
craft advisory (sca) thresholds through at least Friday morning.

Then a 60% chance for SCA level NW gusts across the northern
portion (pzz670) and 40% chance for (pzz673) and even lower chance
for the southern outer waters zone (pzz676). 20% chance for sca
across the outer waters this weekend.

Inner waters N and S of point conception... Winds are expected to
remain below SCA thresholds through this weekend.

Lox watches warnings advisories
Ca... Wind advisory in effect from 2 pm this afternoon to 8 pm pdt
this evening for zone 37. (see laxnpwlox).

Wind advisory in effect from 10 am this morning to 10 pm pdt
this evening for zone 59. (see laxnpwlox).

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.
