Synopsis
Other than continued high surf at the beaches, quiet and
uneventful weather should continue through Thursday, with above
average temperatures and numerous high clouds. A quick hitting
storm system will bring a chance for light rain and mountain snow
showers Friday into Saturday morning. Accumulations should be
light with minimal impact outside of the potential for wet
commutes on Friday. The majority of the upcoming weekend should
be dry.

Discussion For extreme southwestern california including orange...

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

at 1 pm... A high amplitude upper level ridge remained in place
over the western u.S., though it was showing signs of a weakening
trend. Northwesterly flow above 700 mb was pushing ample moisture
over socal, resulting in mostly cloudy skies. Winds were light and
variable across the region. At the beaches surf was generally in
the 5-9 ft range with occasional higher sets evident on the cams
in southern san diego county.

Quiet weather will continue tonight. Patchy fog low clouds may
form near the coast, but should be limited by the high cloud cover
and some light easterly drainage flow.

Ridging will remain in firm control through Thursday. This will
bring weather that is "more of the same", with temperatures
remaining above average and no impacts expected. Low clouds and or
fog should remain patchy at the coast during the overnight and
morning periods. High clouds will also persist as west to
northwest flow above 500 mb continues to send moisture streaming
overhead.

The tail end of a rapidly moving trough of low pressure will swing
through the area on Friday, along with a weak pacific cold front.

Models continue to suggest that moisture and lift will be limited
with this system (gfs pw hovering near 1 inch), so precipiation
amounts look light at this time (perhaps 0.05-0.15 inches for the
populated coast and valley areas with a MAX near 0.5 possible
somewhere along the coastal slopes). Snowfall should be limited by
the moisture and timing of cold air. Advisory level winds are
probable along the deserts slopes. The overall impact of this
system looks minimal at this time, with the most significant
impact being precipiation possible for the Friday commutes.

A few showers may linger into Saturday, otherwise the upcoming
weekend is looking quiet. Global models currently don't suggest
the return of significant ridging, this should leave the door
open for additional precipitation along the west coast early next
week. We just need a system willing to step through it.

Aviation
162100z... Coast... Few areas with vis of 5sm br this afternoon.

Patchy low clouds, with bases 300-600 ft msl and tops near 1000 ft
msl, will develop this evening, but then should push back over the
waters overnight due to weak offshore flow. Vis of 1 sm or less is
possible where low clouds near higher terrain.

Valleys mountains deserts...VFR conditions with broken high clouds
today, turning scattered late afternoon.

Marine
Patchy fog with visibility of 1nm or less is possible again tonight.

Combined seas of 7-11 feet with a long period in the outer waters
south of san clemente island will continue today, then gradually
decrease Wednesday. A low pressure trough will create hazardous
winds and seas Friday through Saturday.

Beaches
High surf will peak through tonight, then gradually decrease
Wednesday. Strong rip currents and surf of 5-9 ft with sets of 10-13
ft are expected. See the high surf advisory and the surf forecast
for additional details. A new swell associated with a pacific storm
will arrive Friday afternoon and continue through Saturday.

Skywarn
Skywarn activation will not be needed this week.

Sgx watches warnings advisories
Ca... High surf advisory until 6 am pst Thursday for orange county
coastal areas-san diego county coastal areas.

Pz... None.
