.SYNOPSIS...24/300 AM.

Another day of well below normal temperatures, then turning warmer
Wednesday through Friday as weak high pressure returns. Night
through morning low clouds and fog are expected for many coastal
areas this week, but decreasing across the valleys. Otherwise
clear skies with mostly light winds are expected.

&&

.SHORT TERM (TDY-THU)...24/827 AM.

***UPDATE***

The marine layer this morning ranged from around 1400 ft deep at
VBG to around 3200 ft deep at LAX. Widespread low clouds extended
from the coast to lower coastal slopes this morning with
generally slow clearing noted thru mid-morning. It looks like the
low clouds should clear back to the coast by late morning or even
early afternoon, with several immediate coastal areas likely to
have minimal clearing thru the afternoon. Otherwise and elsewhere,
mostly sunny skies with a few hi clouds at times will prevail
across the region thru this afternoon.

Good onshore pressure gradients can be expected this afternoon
with the fcst LAX-DAG gradient at +8.2 mb at 00Z. Some gusty SW
winds were noted this morning over the Antelope vly foothills to
the I-5 Corridor. Breezy to gusty SW-W winds will also develop
for many other areas this afternoon.

Temps today are expected to be about 4-8 deg below seasonal norms
in all areas. Afternoon highs should range from the mid 60s to
lower 70s along the coast to the mid 70s to mid 80s for the vlys
and lower mtns, except upper 80s to around 90 in the SLO/SBA
County interior vlys and Antelope Vly.

***From Previous Discussion***

Very low impact weather across southwest California the next few
days and really through at least early next week as well. A trough
of low pressure continues to linger over Central California and
Nevada which will keep temperatures 4-8 degrees below normal
area-wide today.

The trough will exit to the east Wednesday which will begin a
warming trend. Most of the warming will occur on Wednesday when
inland areas jump almost 10 degrees from today`s levels. After
that just very minor upward adjustments to highs Thu. Even with
this warming trend highs will still only be within a couple
degrees of normal in most areas, except around 5 degrees above
normal across the Antelope Valley and far interior SLO County.
Morning low clouds and fog will be less extensive across the
valleys but solid near the coast with typical slow clearing.

.LONG TERM (FRI-MON)...24/258 AM.

High temperatures will remain very similar later this week and
possibly even into early next week as a very weak trough will
persist along the West Coast. Not seeing any large scale gusty
winds coming through the period and temperatures will remain near
normal, except a little above normal inland. Some model solutions
are showing a deeper trough developing early next week that could
fast track a cooling trend.
