.SYNOPSIS...
A little warmer inland for today and Monday. Gradual cooling back
to near seasonal averages expected for the middle to the end of
the week. While chances are still low and uncertainty remains,
confidence is increasing for the potential of monsoonal
thunderstorms over the mountains late in the week. Marine layer
low clouds and patchy fog will spread across the coastal areas
and into the western valleys during the nights and mornings.

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

Update: The marine layer has continued to erode from east to west,
with the IE already clearing out completely and breaks are now
occurring along the I-15 corridor in San Diego County. This should
fully clear for most of the inland areas between 10-11am. There
could be mostly cloudy to broken skies hugging the coastline during
the afternoon hours. Temperatures today will be slightly warmer from
where they were yesterday as high pressure slightly strengthens over
the region. The overall forecast looks to remain on track, with a
cooldown occurring towards the middle of the week, and increasing
monsoonal moisture making its way up from Mexico will allow for a
chance of thunderstorms over the mountains and deserts from Thursday
through the following weekend.

(Previous discussion submitted at 122 AM):

This morning...The marine layer is about the same depth as at this
time yesterday and the low clouds are similar in coverage.
Clearing may be a little faster today than yesterday as the marine
layer inversion seems to be a little weaker.

The dominant ridge will remain centered about 135 miles west
southwest of San Diego through Monday. This will allow inland
temperatures to rise by a few degrees above what they were the
last couple of days. Temperatures in the mtns and deserts will be
several degrees above seasonal averages while west of the mtns,
temperatures will be near or a few degrees below seasonal
averages. This is mostly due to a relatively shallow but
persistent marine layer, with low clouds and patchy fog in the
coastal areas and western portions of the inland valleys each
night and morning. On Monday, a couple of inverted troughs in the
southeast flow on the southern side of the east-west oriented
ridge axis will bring some monsoonal moisture into SoCal but the
threat of afternoon convection will be low because the moisture
will be limited and mostly above 10,000 ft, although a stray
shower or tstm can`t be ruled out altogether.

For Tuesday through the end of the week, model solutions begin to
diverge significantly introducing more uncertainty into the
forecast but in general, the dominant high pressure ridge will be
weakened and displaced eastward towards the Four Corners as a low
pressure system moves inland over the Pacific Northwest. During
this time, temperatures will begin to trend generally lower even
as conditions become drier for Tue and Wed. For Thursday through
the weekend, an increasing number of solutions across model
platforms are indicating an increase in monsoonal moisture with a
corresponding increase in the chances for afternoon showers and
tstms, mainly in the mountains. This change in the pattern will
likely continue the trend toward lower temperatures for the mtns
and deserts.

.AVIATION...
131630Z....Coast/Valleys...Low clouds (based around 1200-1500ft MSL)
have scattered out of the inland valleys and are continuing to
scatter towards the coast at this hour. Localized VIS reductions for
inland valleys to 3-5SM in HZ thru 21z. Clearing to the coast
expected by 18z, though clouds could linger at some beaches through
the afternoon. Clouds develop and push in again late Sun after 02z
with bases closer to 1500ft MSL.

.Mountains/Deserts...VFR conditions and unrestricted VIS through
Monday afternoon.
