Synopsis
A trough of low pressure will spread cooling inland today with
weak offshore flow on Tuesday bringing several degrees of warming
on Tuesday. This will be followed by slow cooling for Wednesday
into Saturday with a return of onshore flow. Stronger offshore
winds are possible for Sunday and Monday with uncertainly on the
timing and strength of the northeast winds.

Discussion For extreme southwestern california including orange...

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

Short term (today through Wednesday)
A trough of low pressure is moving inland into central and
southern california early this morning. The marine layer has
deepened to around 3000 feet with low clouds covering most of the
valleys and spreading into lower portions of the cajon pass.

However, cooling aloft has weakened the inversion with patchier
coverage of low clouds in some coastal areas and across the
coastal waters.

That trough of low pressure will be centered over arizona tonight
with high pressure aloft across central and southern california on
Tuesday with another trough of low pressure moving to just off the
west coast on Wednesday.

Surface high pressure over the great basin will bring gusty east
winds on Tuesday, mainly on the coastal slopes of the mountains of
riverside and san diego counties and in the inland empire below
the banning pass with the stronger gusts mostly 30 mph or less.

There may be another round of gusty east winds on Wednesday
morning, but weaker and with less coverage. Onshore flow will
spread inland on Wednesday afternoon.

High temperatures will cool to near average today, warm several
degrees on Tuesday, then cool slightly on Wednesday. Night and
morning low clouds for tonight into Tuesday morning and Tuesday
night into Wednesday will be confined mostly to areas near the
coast.

Long term (Thursday through Sunday)
The trough of low pressure just off the west coast on Wednesday
will spread inland on Wednesday night and Thursday with weakly
cyclonic flow aloft continuing through Saturday. This will spread
cooling inland for Thursday through Saturday with Saturday high
temperatures near average.

Low clouds may increase in coverage for Wednesday night and
Thursday morning but not extend inland much more than the western
valleys. The marine layer is expected to deepen for Thursday
night into Friday morning with low clouds extending farther inland
into the valleys. The marine layer will become a little shallower
for Friday night into Saturday morning with coastal low clouds
not extending inland much past the western valleys.

For Sunday into Monday, high pressure off the west coast will
amplify with the downstream trough of low pressure strengthening
across the rockies. Surface high pressure will strengthen over the
great basin bringing a much drier air mass into southern
california along with gusty santa ana winds. There continue to be
some timing and amplitude differences with the trough of low
pressure to the east on Sunday and Monday which in turn affects
the timing and strength of santa ana winds for Sunday into
Monday.

Aviation
140900z... Coast valleys... Low clouds based around 3000-3500 feet msl
will cover most of the coastal basin through about 17z, but with
occasional breaks and a random clearing pattern. Areas of low clouds
will return after 04z based lower at around 2000 feet msl and
confined closer to the coast.

Mountains deserts... Clear with unrestricted vis today and tonight.

Marine
No hazardous marine conditions are expected through Friday.

Fire weather
A trough of low pressure moving inland through central and
southern california today will deepen the marine layer and spread
cooling and higher coastal humidity inland.

Surface high pressure over the great basin will bring periods of
gusty east winds for Tuesday into Wednesday. These gusty east
winds will be mainly on the coastal slopes of the mountains of
riverside and san diego counties and in the inland empire below
the banning pass with the stronger gusts mostly 30 mph or less.

There may be another round of gusty east winds on Wednesday
morning, but weaker and with less coverage. Onshore flow will
spread inland on Wednesday afternoon.

Lowest humidity for Tuesday and Wednesday will fall to near 15 to
20 percent for the far inland valleys onto the coastal mountain
slopes. While the combination of lower humidity and gusty winds
will elevate fire weather conditions on Tuesday and Wednesday for
the inland valleys and mountains, critical thresholds are not
expected to be met.

Another round of gusty offshore winds is expected for Sunday into
Monday. This will bring a much drier atmosphere into southern
california. There is less confidence in the strength and timing of
stronger winds. Critical fire weather conditions may develop on
Sunday and continue into Monday, especially for the mountains and
valleys.

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