Synopsis
The high will bring temperatures that are well above normal for the
inland areas and around normal at the coast into Monday. The skies
should be fair except where the onshore flow brings in a coastal
overnight marine layer through next week. A low will approach by
Tuesday for a cooling trend and increasing cloudiness into midweek.

Short term (tdy-sun)
pretty big increase in low lvl southerly flow today resulted in a
significant cooling trend for coastal valleys south of pt
conception today. Farther interior areas above the marine lyr saw
little change other than an increase in winds. Not seeing a lot of
change in the pattern for tomorrow as gradient trends are
generally flat and there are minimal changes aloft. However, interior
areas north of pt conception should see a little cooling from
today as some of that cooler maritime air moves inland. Marine lyr
clouds will again struggle to clear the coast from about malibu
north.

By late Friday into Saturday the low lvl flow is expected to
reverse as surface high pressure strengthens to the north. This is
expected to lead to a noticeable warming trend in most areas
Saturday along with some increase in north winds through the santa
ynez range and i5 corridor. These trends will continue into Sunday
which should be the warmest day of the period. Marine lyr is
expected to shrink in depth and areal coverage with clouds mostly
confined to the beaches north of pt conception and coastal la
county. It's possible the current heat advisory may need to be
expanded to cover some additional valley areas Saturday and or
Sunday.

The NAM continues to show an increase in instability aloft
Saturday as some high level moisture and energy moves in from the
south. There are some decent lapse rates at very high levels but
the moisture is confined to 600mb and above. Not real confident in
this as the other models are much less unstable and don't really
show much in the way of short wave features coming in from the
south. So for now will just indicate some high clouds moving in
Saturday but no thunderstorms. The main concern would be for dry
lightning given the lack of low lvl moisture but right now the
threat appears to be too minimal to include in the forecast.

Long term (mon-thu)
still very warm Monday but an increase in onshore flow should lead
to at least a few degrees of cooling for inland areas. Onshore
flow expected to increase a little each day through Thursday as a
series of troughs moves into the pac nw. Confidence on the extent
of cooling beyond Tuesday is pretty low as models still show a lot
of differences with regard to how fast the high pressure ridge
will weaken and shift east. The GFS remains the coolest and
trending towards that solution for now.

Aviation 22 1800z.

At 1748z at klax... The marine layer depth was 1900 feet. The top
of the inversion was around 3500 feet with a temperature of about
27 degrees celsius.

The marine layer will clear from most coastal sections, but some
taf sites will not clear until late afternoon or not at all. Most
taf sites will haveVFR conditions except for MVFR conditions
where the marine clouds fail to clear out. The marine clouds will
return to the coastal and valley sections with ifr conditions again
tonight into Friday morning. There is good confidence in the 18z
taf forecast.

Klax... Good confidence in the 18z taf. There is a 30 percent
chance of the marine clouds moving in plus or minus two or more
hours than the forecasted time.

Kbur... Good confidence in the 18z taf. There is a 30 percent
chance of the marine clouds moving in plus or minus two or more
hours than the forecasted time.

Marine 22 900 am.

Winds will remain below small craft advisory (sca) level through
Friday then increase to above SCA levels in the outer waters Saturday
through Monday.

A 2-3 foot south swell will last through much of the week and
pose a risk for breaking waves nearshore. People boating or
kayaking near shore should use extra caution this week. A small
(2-3 feet) short period swell will impact the santa barbara
channel and santa monica basin over the weekend.

Although the coverage of dense fog is easing a bit, there is still
the possibility of patchy dense fog during the night and
mornings.

Fire weather 22 1030 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. Onshore
winds will peak today and Friday, which will focus the concerns to
interior los angeles county including the angeles national
forest, highway 14 corridor, and the foothills of the antelope
valley. 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 Friday night and
Saturday. While this should have little impact on humidities at the
surface, this has a 10 percent chance of producing high-based
thunderstorms. Confidence is incredibly low with this, but the
potential for dry lightning exists.

A red flag warning is in effect through 9pm this evening for
the interior los angeles county mountains and foothills where the
driest and windiest conditions of the period are expected.

Otherwise, with rapidly drying fuels vegetation, elevated fire
weather concerns through Monday, primarily 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
38-52-53. (see laxnpwlox).

Beach hazards statement in effect through Saturday evening
for zones 40-41-87. (see laxcfwlox).

Excessive heat warning in effect until 9 pm pdt Sunday for
zones 54-59. (see laxnpwlox).

Red flag warning in effect until 9 pm pdt this evening for
zone 254. (see laxrfwlox).

Pz... None.

Hazard potential outlook (sun-thu)
hot temperatures with potential heat impacts will continue for
inland areas Sunday.
