Synopsis 17 657 pm.

Night through morning low clouds will continue cover the coast
and valleys throughout the week with a cooling trend through
Saturday. A four corners high pressure system will expand westward
into the region on Sunday and last through next week bringing
another spell of summertime heat.

Short term (tdy-sat) 18 247 am.

The marine layer is 2000 ft deep at klax. There is weak-moderate
onshore flow both to the north and east. Low clouds have slowly
been filling in overnight and by dawn almost all of the coasts and
vlys will be covered by stratus. Strong onshore flow this
afternoon will keep more than a few beaches cloudy and will bring
30 to 40 mph wind gusts to portions of the antelope vly. MAX temps
will cool again today and will be below normal everywhere today
but especially in the vlys where MAX temps will be5 to 10 degrees
blo normal.

Not much change meteorological parameters either Friday or
Saturday and expect conditions very similar to today. A little
more onshore flow and lower hgts will bring a degree or two of
cooling to the area and will make it the coolest day of the next 7
(and the day that will be missed the most next week when temps
soar) then slightly higher hgts and weak offshore trends will
bring temps back up to todays values on Saturday.

Long term (sun-wed) 18 316 am.

Both the ec and GFS agree that on Sunday a large upper high moves
out of the tx panhande and over to the four corners area where it
will persist through all of next week. The western third of this
upper high will cover SRN ca. Hgts will be in the 592-594dm range.

The onshor gradients will weaken through the period and actual
offshore flow from the north is forecast by next Tuesday. The
marine layer stratus will be smooshed out of the valleys, but will
continue over the coasts during the night through morning.

Afternoon clearing will be a little bit of a challange. On one
hand the gradients are weak enough to support the notion of total
clearing, but on the other the shallow marine layer coupled with
a very strong inversion could well keep the stratus trapped at the
beaches.

Max temps will be above normal away from the beaches and will not
vary much from day to day. Right now the only triple digit heat is
forecast for the antelope valley, but would not be surprised if
max temps came in a little hotter than currentlly forecast.

Current mdl fcst keep the monsoon push away from la county through
Tuesday and then brings a little moisture into the area starting
next Wednesday. Still anytime there is a four corners high a
monsoon push is possible so will have to keep a day to day watch
on it as we draw closer to the start of next week.

Aviation 18 1043z.

At 0758z, the marine layer depth was around 2200 feet deep at
klax. The top of the inversion was was near 3400 feet with a
temperature around 23 degrees celsius.

N of point conception... Moderate confidence with a persistent
stratus pattern with ifr CIGS for coastal TAF sites. There is a
40% chance for brief lifr conds between 12-14z this morning.

Slightly lower confidence for lifr ifr CIGS at kprb between 12-16z
this morning. Timing of stratus scouring will be + - 1 hour. Look
for a similar time pattern once again for lifr ifr stratus once
again late this evening into Fri morning.

S of point conception...

mainly MVFR conditions are expected across coastal TAF sites.

There is a 40% chance that kbur and kvny could go down briefly to
ifr between 12z-14z. Stratus should scour out + 1 hour from taf
times.VFR conditions should develop later today. There is a 30%
chance of MVFR conditions lingering at coastal terminals into the
late afternoon hours.

Klax... MVFR conditions should linger through at least 18z. There
is a 30 percent chance of MVFR conditions lingering until as late
as 22z.

Kbur... There is a 40 percent chance of ifr conditions at kbur
between 12z-14z.VFR conditions should develop between 16z and
18z.

Marine 18 148 am.

For the outer waters... Expect winds will remain below SCA levels
through the period, although near-sca conditions (10 to 20 kt)
are expected Friday and Saturday nights.

For the all of the inner waters, conditions will remain below
advisory levels through at least Monday.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (sat-wed)

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
