Synopsis
Warm and dry today with variable high clouds and some patchy low
clouds and fog near the coast this morning. A weakening low
pressure system will move through the area on Tuesday bringing
more clouds and some cooling. The next low pressure system behind
that is expected to spread precipitation southward through
california, reaching far southern california on Wednesday night
and early Thursday. A few showers are also possible Friday night
into Saturday morning, mainly for san diego county. Offshore flow
may follow for Sunday with gusty northeast winds for the mountains
and inland valleys.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

Short term (today through Wednesday)
Early this morning, there is weak onshore lower level flow over
the coastal waters and weak onshore flow inland. The marine layer
is around 1200 feet deep. Satellite imagery shows patchy stratus
over the coastal waters extending locally inland near the coast,
mainly in orange and northern san diego county. There are locally
gusty east to northeast winds near the coastal slopes of the
mountains, mostly 25 mph or less. These winds are expected to
continue through this morning, then dissipate.

Satellite imagery also shows a low pressure system over the
eastern pacific centered near 30n 130w, roughly due west of
northern baja. This low pressure system will weaken and move
slowly eastward, moving inland across southern california and
northern baja on Tuesday. The high cloud shield with this system
will overspread southern california today. Frontal band
precipitation with this system is mostly expected to dissipate by
the time it reaches the coast.

A second, larger low pressure system over the eastern pacific will
continue to move toward the west coast. Precipitation from this
system is expected to reach the coast of northern and portions of
central california late Tuesday night and early Wednesday, then
move southward through the state for Wednesday and Wednesday
night. In the area of weak lower level warm advection ahead of the
cold front, some light precipitation could develop late Wednesday
into Wednesday evening in areas bordering los angeles county to
the east.

The cold frontal precipitation band is expected to reach point
conception late Wednesday afternoon, pushing eastward across
southern california Wednesday night and early Thursday. This front
is expected to be weakening as it moves eastward across southern
california with progressively lesser amounts as one moves east and
south of los angeles county.

While some lighter precipitation is possible late Wednesday
afternoon into Wednesday evening, the bulk of the precipitation
for areas east and south of los angeles county is expected from
late Wednesday evening through Wednesday night and early
Thursday. Across orange and southwestern san bernardino counties,
rainfall is expected to range from around one quarter inch near
the coast to one half to three quarters of an inch in the
mountains with locally greater amounts. Amounts are then expected
to decrease from north to south across san diego county with
around one tenth inch across southern san diego county. Rainfall
around one tenth to locally one quarter inch is expected across
high desert areas with mostly one tenth inch or less in lower
desert areas.

Long term (Thursday through Sunday)
Some showers may linger along and west of the mountains into
Thursday afternoon, mainly for the mountains and inland valleys.

Dry weather is expected for Thursday night and Friday under weak
high pressure. Another low pressure system will move inland
farther to the north, moving across the pacific northwest on
Friday and through the great basin on Saturday. As it does so, it
will strengthen the onshore flow across southern california. The
combination of that stronger onshore flow and weak instability
across the coastal waters from colder air aloft moving across the
warmer sea surface temperatures of the coastal waters, could bring
some scattered mostly light showers from the coastal waters
inland to mountains, mainly in san diego county as shown by the
ecmwf. Dry weather is then expected to prevail through Sunday with
gusty offshore winds possible Sunday.

Aviation
191000z... Patches of low clouds, with bases 300-1000 ft msl and tops
to 1300 ft msl, will meander along the coast this morning before
clearing by late morning. Vis of 2-4 sm br is expected for most
areas where low clouds develop, with isolated areas of fg.

Conditions will improve by late morning, then a weak coastal eddy
will help develop a greater area of stratus over the coast and
valleys tonight with higher tops and bases. Otherwise, sct-bkn high
clouds at above 20000 ft msl will prevail through tonight.

Marine
No hazardous marine weather is expected through Thursday. Wind gusts
near 20 kt are possible Friday, mainly across the outer coastal
waters.

Fire weather
Lower level flow today will be weakly onshore near the coast and
weakly offshore for inland areas. There will be locally gusty east
to northeast winds near the coastal mountain slopes this morning,
mostly 25 mph or less. Humidity near the coastal mountain slopes
and far inland valleys near 20 to 25 percent early this morning,
will fall to around 15 percent today. Inland humidity is expected
to recover on Tuesday as a weakening low pressure system moving
inland through southern california and northern baja brings
stronger onshore flow spreading higher coastal humidity inland.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
