.SYNOPSIS...
A trough of low pressure along the West Coast will keep a dry,
southwest flow aloft and slightly below average temperatures over
southern California through much of the week. The marine layer and
onshore flow will continue areas of coastal low clouds and patchy
fog each night and morning, extending into the valleys. A little
warmer by the weekend as high pressure rebuilds.

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

Marine clouds were extensive again this morning over the coastal
waters and inland up to 30 miles across the coastal basin. Above the
marine layer and inland over the mts/deserts, skies were clear. The
12Z Miramar sounding indicated an unexpected 500 FT drop in the
depth of the marine layer, with the base of a 10 degree C inversion
near 2500 FT. The sfc pressure gradients were barely holding onshore
to NV, but continued onshore around 6 MBS KSAN to the deserts.

Only minor changes are expected in our weather today due to the
change in depth of the marine layer and a continued cooling of the
sea surface temperatures. The near-shore buoys have all shown a drop
of between 2 and 3 degrees F over the past few days. This will
contribute to both low/high temps along the coast trending
closer to average, or slightly below for the next few days.

The synoptic pattern will not change much this week, with a longwave
trough over the west, and a strong ridge over the eastern half of
the country. The trough reaches maximum amplitude about Wed, then
slowly drifts east, so look for extensive marine clouds/patchy fog
each night/morning, followed by sunny and mild days. As the trough
drifts east late in the week, heights/thickness recover across the
SW, which will bring warmer weather and less extensive low clouds.

While monsoonal moisture will return to the Desert SW this week, it
does not look it will make it this far west due to SW flow aloft.
And even though the models show some return of mid-level moisture
here late in the week, the pattern is not supportive of any
shwr/tstm activity over our mts/deserts. The latest operational runs
of the GEM/ECMWF/GFS all favor a return of the western longwave
trough/eastern ridge pattern next week. This also does not favor a
return of the Monsoon to SoCal through mid month.

.AVIATION...
071500Z...Coast/Valleys...Low clouds, with bases of 1300-2100 ft MSL
and tops near 2500 ft MSL, will slowly clear in the valleys this
morning, and likely linger along the coast throughout the day due to
a 10 C marine layer inversion. Vis of 3-5 SM BR/HZ over inland areas
will become P6SM by late morning. Low clouds, with slightly lower
tops and bases, will redevelop and push around 30 miles inland by
early Monday morning.

Mtns/Deserts...Mostly clear with unrestricted vis through Monday
morning.

.MARINE...
No hazardous marine weather is expected through Thursday.
