Synopsis
Onshore flow will maintain seasonal weather through tonight.

Beginning on Sunday, winds will begin to turn offshore and become
gusty along the coastal slopes, drying and warming the atmosphere
over southern california. Building high pressure aloft will add to
the warming, resulting in well above average temperatures and
increased wildfire risk. Fair skies, warm days, very low humidity,
and periods of gusty easterly winds will prevail much of the coming
week.

Discussion For extreme southwestern california including orange...

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

there were just a few isolated patches of low clouds indicated in
satellite imagery offshore this morning. Otherwise the skies were
clear. The sfc pressure gradients were trending weakly offshore from
nv, and maintaining weak onshore to the lower deserts. Wind reports
across the region were light. The 12z miramar sounding had 5c sfc-
based inversion. Little change is expected today with temps climbing
into the 70s and lower 80s most areas. It will be in the 60s
in the mountains and near 90 in the lower deserts under mostly clear
skies. The marine forecast was updated earlier this morning due to
rough seas in the outer waters. Please see marine discussion below.

From previous discussion...

winds turn more west-northwesterly in response to a trough moving by
to the north this evening, with breezy conditions expected in the
mountains and deserts.

Offshore flow quickly follows for Sunday morning in san bernardino,
riverside, and orange counties, mainly below the passes and canyons.

Peak wind gusts will generally be around 30-40 mph below the cajon
and san gorgonio passes as well as northern portions of the santa
ana mountains. Winds shift more easterly on Monday morning with
breezy conditions developing along the coastal slopes and foothills
of the san diego county mountains. Peak gusts will remain in the 30-
40 mph range. Gusty winds will continue into Tuesday morning before
weakening Tuesday afternoon. For the early part of next week, the
upper level high off the west coast slowly shifts east with a ridge
axis expanding over so cal. This will lead to a notable warming
trend. By Tuesday highs in the valleys could reach the mid 90s, with
some low to mid 80s even at the beaches.

Onshore flow briefly returns Wednesday as another trough passes by
to the north, bringing some cooling, though temperatures will
remain several degrees above normal. The return of offshore flow
looks likely for Thursday into the weekend. Ec ensembles suggest
winds will be stronger than the event earlier in the week. Gfs
ensemble has been trending stronger as well. Still too early to
say exactly how windy it will be. There could be more low level
cold air advection with the late week event as well, so expect
some cooling in the mountains and deserts and only minor warming
west of the mountains.

Aviation
191430z... Mostly clear with unrestricted visibility through Sunday,
with only a few high clouds above 20,000 feet at times.

Marine
A small craft advisory for hazardous seas is in effect through 11 am
Monday for the outer waters. Seas of 7-8 feet with an 8 second
period will generate steep seas. Highest seas will be near san
clemente island. Wind gusts could reach 20 knots at times, though
the stronger winds that will generate the short period swell will be
farther west.

Fire weather
Onshore flow will prevail today for seasonal temperatures and
humidity. Northeast to east winds develop early Sunday below the
cajon, san gorgonio, and morongo passes and into the santa ana
mountains. Winds will mostly be around 15-25 mph with gusts to 35
mph. Isolated gusts near 40 mph are possible in the favored passes
and canyons. Winds shift more easterly Sunday night into Monday
with winds spreading into the san diego county mountains and
foothills. Wind speeds will generally remain 15-25 mph with gusts
to 35 mph. Winds weaken some Monday afternoon with breezy
conditions continuing into Tuesday morning. Significant weakening
occurs Tuesday afternoon.

Daytime humidity will be around 10-20 percent on Sunday, with some
recovery expected Sunday night. Widespread humidity of 10-15 percent
on Monday and Tuesday as significant warming occurs. The combination
of gusty winds and low humidity will lead to a few hours of critical
fire weather conditions Sunday and Monday during the late morning
and afternoon.

Onshore flow returns on Wednesday for some improvement in
conditions, but potentially stronger offshore flow and widespread
drying is possible Thursday into next weekend.

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

Sgx watches warnings advisories
Ca... None.

Pz... Small craft advisory for hazardous seas until 11 am pdt Monday
for waters from san mateo point to the mexican border

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
