.SYNOPSIS...16/1214 AM.

Night through morning low clouds and patchy fog will continue for
the coasts and most valleys through much of this week. A cooling
trend will continue through Thursday when valley highs are only
expected to be in the 80s. A slow warming trend will develop by
the weekend with highs close to normal.

&&

.SHORT TERM (TDY-FRI)...16/1214 AM.

A weak eddy and strong onshore flow will bring the marine layer up
to about 3000 ft this morning. As a result marine layer stratus
will advance all the way to the coastal slopes and will cover all
of the vlys including the Santa Clarita. Slight offshore trends
this afternoon will allow for slightly better and faster clearing
although a few west facing beaches will likely remain cloudy all
day. The deep marine layer will bring cool temps to the area with
max temps ranging from 3 to 6 locally up to 10 degrees blo normal.
The warmest vly locations will only see highs in the mid 80s.

On Thursday a weak upper low moves into nrn Mexico and shift the
upper level flow to the SE. This will pump in some monsoon
moisture. Mdls still showing the greatest chc of convection to the
SE and E of LA county. Mdls show the best moisture over LA County
to be over 700 mb with uninspiring LIs and CAPE values so current
forecast of 10 percent chc of convection seems good. The morning
low clouds will persist but better clearing will allow for a
couple of degrees of warming for most of the area.

Offshore trends (esp in the afternoon) will lead to less marine
layer cloud coverage and much better clearing. This faster
clearing will bring an additional couple of degrees of warming to
most areas. Max temps, however, will remain 2 to 5 degrees blo
normal. Continued SE flow aloft will keep the 10 percent chc of
afternoon convection going over the mtns. Still limited
instability and CAPE will likely prevent anything from developing.

.LONG TERM (SAT-TUE)...16/306 AM.

Excitement meter barely moving in the long term. On Saturday the
upper low will move away and the far western edge of a large upper
high will slowly move over the area. At the sfc, onshore flow will
be at a minimum on Saturday and then will slowly increase Sunday
through Tuesday. The night through morning low clouds will
continue at the coasts and will slowly filter back into some of
the vlys. The increase in onshore flow will be counteracted
somewhat by the increasing hgts which will keep some vly areas
clear.

Max temps will rise 1 or 2 degrees on Saturday but then will not
change much over the next three days. Max temps will continue to
run 3 to 6 degrees blo normal.

The monsoon door will be closed and there do not look like there
will be any wind issues either.

.AVIATION...16/0058Z.

Around 2330Z, the marine layer depth was around 1200 feet deep at
KLAX. The top of the marine inversion was at 2400 feet with a
temperature near 24 degrees Celsius.

Moderate confidence in flight categories. High confidence in
timing of arrival. IFR to MVFR conditions will spread into coastal
and valley terminals through 10Z. There is a moderate chance of
LIFR conditions at terminals north of Point Conception between 08Z
and 16Z. There is a moderate chance of clearing later than
forecast at coastal terminals.

KLAX...IFR to MVFR conditions will spread into KLAX as soon as 01Z
or as late as 03Z. There is a 30 percent chance that conditions
could end up being predominantly MVFR through the period. VFR
conditions could develop as soon as 17Z, or as late as 20Z.

KBUR...IFR to MVFR conditions will spread into KBUR as soon as
05Z or as late as 08Z. There is a 20 percent chance that
conditions could end up being predominantly MVFR through the
period. VFR conditions should develop around 17Z.

&&

.MARINE...15/741 PM.

Tonight through Thursday, winds and seas are expected to remain
below Small Craft Advisory (SCA) levels across all the coastal
waters. For Friday through Sunday, winds will begin to increase
with a 20-30% chance of SCA level winds around Point Conception.
