.SYNOPSIS...23/819 PM.

Expect cooler temperatures through Tuesday, then warmer again
Wednesday through Friday as 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 (MON-THU)...23/132 PM.

Synoptically, there is an upper level trough extending southwards
across California while a very strong (595 dam) upper High is over
the Eastern US. 578 dam heights overhead will grow to about 588
dam by Wednesday as the trough fills. By Friday the pattern
becomes zonal and the lower two thirds of the US will be under a
broad area of higher heights.

Non-impactful weather is expected for the rest of today. Low end
instability indicated possible cloud buildup today, and some
cumulus is starting to develop over mountainous areas, but PWAT
values are low (below 0.5 inches) so not expecting any rain today.
The upper level trough brought a return to onshore flow and cool
temperatures. Afternoon highs will finish 4-8 degrees below normal
in most areas today.

Expecting night to morning low clouds and stratus overnight, with
a similar inland extent on Tuesday morning. Expect very little
change from today`s weather.

As the trough weakens and moves east on Wednesday temperatures
will warm several degrees, with afternoon highs back to near or
slightly above seasonal normal.

The trough will continue to weaken on Thursday and temperatures
will warm another degree or so. Downtown LA will be in the low
80s, Paso Robles in the mid 90s, and the Antelope Valley could
reach 100.

.LONG TERM (FRI-MON)...23/137 PM.

Minimal day-to-day temperatures changes are expected in the
extended period, with highs in the 80s to lower 90s in the
valleys and mostly 70s closer to the coast. High pressure aloft
should confine the marine layer to coastal areas and possibly
portions of the San Gabriel and Santa Ynez Valleys.

Temperatures are expected to peak on Saturday and then slight
cooling is projected through Tuesday as weak trough may return to
the West Coast.
