Synopsis
A low pressure trough over the west will keep it comfortably cool
again today. The trough will weaken next week, allowing surface high
pressure to build over great basin, which will turn the winds
offshore over southern california. This will set the stage for
sunny, warmer days, and clear, cool nights through the end of the
month. The drying northeast winds will become gusty at times along
the coastal foothills, especially Monday and Tuesday, increasing
the threat of wildfires.

Discussion For extreme southwestern california including orange...

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

once again overnight low clouds were mostly confined to the
foothill and lower coastal slopes, with only scattered clouds
farther west. Weak onshore sfc pressure gradients continued ksan to
the lower deserts, while they were weak offshore from nv. At 2
am pdt winds were mostly light.

The deep, longwave trough over the west has reached its peak this
morning and will begin lifting out through the great basin and on
through the high plains Mon tue. This will allow surface high
pressure to build south across the ca deserts and turn the winds
over socal offshore. The winds should peak Mon Tue mornings before a
secondary trough develops back across the great basin and settles
as a cut-off low over the lower colorado river valley again on wed.

This system will have little net sensible weather effect over socal,
but it will serve to limit the extent, strength, and duration of the
offshore event by weakening the sfc gradient.

Even though the offshore winds will be modulated, they will still
mark a noticeable weather change here, punctuated by warmer days with
much lower humidity, and cooler nights with few if any clouds until
the marine layer can become reestablished again, perhaps late next
week. Indications are that it will remain on the warm side and dry
for early october with high pressure over the sw.

Aviation
230830z... Coast valleys coastal slopes... Sct-bkn clouds with bases
2500-5000 ft msl locally obscuring higher terrain through 17z.

Clouds becoming few-sct after 17z with mostly clear skies and
unrestricted vis prevailing through Sunday morning.

Mountains deserts... Clear with unrestricted visibility through
Sunday morning.

Marine
No hazardous marine weather is expected through Wednesday.

Fire weather
Offshore flow will develop on Sunday, and become gusty below the
coastal slopes, canyons and passes of san bernardino, riverside, and
orange counties Mon tue. The rh will drop considerably, on Sunday
with minimum daytime values in the 10-15% range through Thursday. In
the favored, offshore wind-prone areas, we are still expecting to
see local winds of 25 to 35 mph with isolated gusts topping 40 mph,
especially Mon Tue mornings. Several hours of near critical fire
weather conditions are possible in these foothills areas, mainly
north of san diego county Mon Tue due to the low rh and winds
exceeding 25 mph. However, with the limited coverage and duration of
critical conditions, no fire weather product issuance is anticipated
at this time.

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