Synopsis 19 1200 pm.

Night through morning low clouds are expected over the coast and
adjacent valleys this weekend, gradually receding from the valleys next
week. Temperatures will trend warmer into early next week as high
pressure dominates the area.

Short term (tdy-mon) 19 154 pm.

Very similar day today as yesterday except better clearing of the
marine layer south of pt conception. Temps were a few degrees
cooler inland but around the same near the coast. Low clouds
expected to reform overnight and spread into the valleys and cover
most of the same areas as this morning. The high to our east will
start building west Saturday but likely only result in a very
slight (1-2 degree) warmup for inland areas. Otherwise Saturday
should be very similar to today.

The warming trend will kick into gear Sunday and continue through
early next week as the high strengthens and onshore flow weakens.

Highs will bounce back to normal levels by Sunday or Monday. The
marine layer depth will lower dramatically Sunday and remain
shallow next week but should still provide a cooling influence for
the coastal areas with some dense fog possible at times in the
morning hours. Some high clouds are possible at times generating
partly cloudy skies as southeast flow aloft pulls in some high
level moisture but too dry at lower levels for thunderstorms.

Long term (tue-fri) 19 209 pm.

The warming trend will continue Tuesday then mostly level off
there through Friday with just minor day to day changes. As
yesterday the forecast temps are all slightly warmer than the mos
guidance numbers which may be factoring in the increase in
moisture from the southeast. Models have gone back and forth on
this but la county continues to be on the very western edge of the
deeper moisture (today was less favorable) so there is some
uncertainty with the temperatures and also with the potential for
thunderstorms. Deeper moisture would likely lead to a cooler but
more humid forecast but will keep leaning towards the higher end
of the ensemble members for next week's highs. This would bring
another round of lower 100s to the coastal valleys possibly for
several days going into next weekend. Onshore flow is weakest
tue-thu so those would be the warmest days for coastal areas but
still mostly just 80s at best there.

Will keep in the slight chance of thunderstorms for the extreme
eastern san gabriels Wed but there are non-zero chances on other
days as well depending on how the pattern sets up. The bulk of the
monsoon moisture is well to the east and south so chances are much
lower for this area.

Models now showing the 4 corners high shifting even farther west
over california Friday through next weekend so there is the
potential for even warmer temps, mainly just far inland areas like
the antelope valley where highs around 110 are possible. Still
above normal for coast and coastal valleys but models maintain a
pretty decent onshore flow so highs shouldn't get much warmer
than earlier in the week.

Aviation 19 1758z.

At 1730z at klax, the marine layer was 2200 ft deep. The top of
the inversion was near 5300 feet with a temperature of 19 deg c.

Moderate confidence overall in the 18z tafs. The marine layer
pattern will continue thru the TAF period, with low clouds and
ifr MVFR CIGS expected at the coast and vly airfields including
kprb mainly for the night and morning hours, altho some airfields
will have persistent MVFR CIGS into mid afternoon today. However,
low clouds with mainly MVFR CIGS should linger thru this afternoon
for ksmx then lower to ifr this evening. The timing of the onset
and any dissipation of the low clouds may be off + - an hour or
two.

For kwjf and kpmd, there is hi confidence in the 18z tafs with
vfr conditions thru the TAF period. There will also be gusty
afternoon and evening SW winds today.

Klax... Moderate confidence in the 18z taf. Low clouds with MVFR
cigs will return to the airfield around 05z this evening then
linger thru about 20z sat. Otherwise,VFR conditions can be
expected. The timing of the onset and dissipation of the low
clouds may be off + - an hour or two.

Kbur... Moderate confidence in the 18z taf. Low clouds with MVFR
cigs will return to the airfield around 10z late tonight then
linger thru about 17z sat. Otherwise,VFR conditions can be
expected. The timing of the onset and dissipation of the low
clouds may be off + - an hour or two.

Marine 19 101 pm.

For the outer coast waters, winds and seas are expected to remain
below small craft advisory (sca) levels through Monday. However
there is a 30% chance for SCA conditions due to winds late this
afternoon through late this evening for areas S of point
conception. There will then be a 40 percent chance of SCA level
winds at times Monday night through Wednesday, especially for the
northern 2 outer waters zones (pzz670 and pzz673).

For the inner and nearshore waters, winds and seas will likely
remain below SCA levels tonight through Wednesday.
