Synopsis
A slight chance of showers and thunderstorms for the coast and some
valleys north of los angeles into Saturday morning. The high will
bring temperatures that are well above normal inland, and normal
at the coast Saturday into Monday. The skies should be fair except
for an overnight marine layer through next week. A low will move
in Tuesday through Thursday for a cooling trend and increasing
cloudiness. Then the end of the week may be in transition as the
low exits.

Short term (tdy-sun)
marine lyr running deeper today but we're already starting to see
a reversal in the gradients this morning, both north south and
east west. This is likely why clouds are clearing fairly rapidly
this morning. They will still struggle to clear away from the
beaches, especially from malibu north and west but otherwise a
pretty typical clearing trend. Highs today south of pt conception
should be with a couple degrees of yesterday while up north most
areas should be 3-6 degrees cooler.

Main feature we're watching this morning is the moisture moving up
from mexico. Lightning has been detected in some of the clouds
over the waters about 60 miles south of the border. This goes
along pretty well with what the NAM has been showing as far as
instability aloft and moisture mainly above 600 mb. The feature is
expected to continue tracking northwest mostly over the ocean but
should clip the western portion of our land CWA (mainly sb slo
counties but possibly the western part of ventura county) tonight
and early Saturday. It's still very dry at lower levels but given
that we're already seeing some lightning from it and the nam
continues to show mucapes between 500-1500 j kg overnight it seems
prudent to go with at least some chance of dry thunderstorms.

Can't rule out a brief shower reaching the surface through all the
dry air but the main concerns are lightning and gusty winds.

By afternoon Saturday the air mass stabilizes and chances for
thunderstorms decrease. Meanwhile, temperatures should climb
several degrees Saturday as the marine lyr decreases and
gradients trend offshore. We could see triple digit heat returning
to some of the coastal valleys Saturday and or Sunday.

***from previous discussion***
the ridge pushes slowly to the east on Sunday but not really fast
enough to influence the temps. In fact the day will be very
similar to Saturday except that the mtns will be more stable and
thus there will be no afternoon clouds.

Long term (mon-thu)
gfs and ec agree through Tuesday. Both mdls flatten the ridge as
well as pushing it southward hgts fall from 593 dm to 590 dm
Monday and to 588 dm Tuesday. Onshore flow increase to the east
but decreases and actually turns offshore Tuesday. So there will
be a general cooling trend ESP inland through the period with the
exception of few vly location below north oriented canyons. Buy
Tuesday MAX temps will approach or reach normal at most locations.

The Wed and Thu forecasts are still in doubt as ec and gfs
continue to exhibit different forecasts. The ec begins to build a
ridge into the area while the GFS continues with the troffing
scenario. Both mdls have hung on to their respective fcsts for a
couple of days now it will be interesting to see which one blinks
and trends to the other's solution (hopefully it will not be the
annoying situation where both mdls change and adopt the others
forecast) for now have coordinated with the surrounding offices
and have agreed to persist with the cooler GFS soln.

Aviation 23 1800z.

At 1723z at klax, the marine layer depth was 1700 feet. The top
of the inversion was around 4600 feet with a temperature near 27
degrees celsius.

Low to moderate confidence in the 18z tafs. Today is roughly
similar to yesterday as a few coastal locations are expected to
struggle to clear this afternoon. The main element of doubt with
the forecast is the possibility of weaker onshore flow tonight and
Saturday causing a reduction in marine cloud coverage. For now,
we have kept the marine clouds in the valleys, but do not be
surprised if the valley tafs soon reflect a sunnier, more
optimistic tone. Elsewhere the marine clouds will return tonight
with another round of MVFR to ifr conditions.

Klax... Moderate confidence in taf. There is a 30 percent chc of no
afternoon clearing. Very high confidence that there will not be an
east wind component over 5kt.

Kbur... Low to moderate confidence in the 18z taf. There is a 40
percent chc that CIGS will not make it into the airfield tonight at
all.

Marine 23 900 am.

Winds will remain below small craft advisory levels through
Friday night across the outer waters, then gradually increase
through Monday. There is a 50 percent chance of small craft
advisory level winds developing Saturday morning with a better
chance by the afternoon across the outer coastal waters. Across
the inner waters, confidence is high there will not be any sca
through the weekend. However there will be a 50-60% chance for
local gusts to 25 kt across the W portion of the sba channel.

A 2-3 foot south swell at 16-17 second period will last through
Saturday and may pose a risk for breaking waves nearshore. People
boating or kayaking near shore should use extra caution.

Although the coverage of dense fog is easing a bit, there is still
a 40% chance of patchy dense fog during the night and mornings
through the weekend.

Fire weather 23 900 am.

Hot and dry conditions will continue through Monday of next week.

The hot conditions will also bring the potential for plume
dominated fires which can create their own intense winds. Gusty
onshore winds will continue today focusing the concerns to
interior los angeles county. Weaker but locally breezy northwest
winds should follow Saturday through Monday... Shifting the area of
concern to santa barbara county and the tejon pass.

Tropical moisture aloft will move through the area tonight and
Saturday. While this should have little impact on humidities at
the surface, this moisture is producing a small area of high-
based thunderstorms. If this feature persists, dry lightning will
be a major concern as an ignition source with little to no rain.

With such conditions, elevated fire weather concerns will persist
through Monday, especially over all interior sections away from
the influence of the marine layer. If fire ignition occurs,
dangerous fire behavior should be expected. As such, the public
should be extreme careful when handling potential ignition sources
such as cigarettes, campfires, hand torches and metallic weed
trimmers.

Lox watches warnings advisories
Ca... Heat advisory in effect until 9 pm pdt Sunday for zones
38-52>54. (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.
