Synopsis
A weakening cold front will bring light rain to the area late
tonight into early Saturday morning. Monday a dry inside slider
will result in gusty northerly winds and cooler air. Weak ridging
aloft and northerly winds at the surface will bring warm and dry
conditions for the middle of next week.

Short term (tdy-mon)
increasing clouds were noted over slo county early this afternoon.

Some rain was just north of the area moving into monterey county.

The rain was associated with an approaching cold front, which is
expected to move southward and affect nwrn slo county with some rain
by late today. Otherwise, mostly sunny skies should cover much of
the forecast area thru this afternoon altho some increasing mid and
hi clouds should affect sba county. Temps this afternoon should be a
few degrees below normal for the coast and vlys, and several degrees
above normal for the mtns and deserts. Highs in the warmest vlys and
inland coastal areas are expected to be in the upper 60s to lower
70s.

An E pac upper trof and surface cold front will move inland over the
region tonight into Sat morning. This system will bring rain to much
of slo/sba counties tonight. The chance of rain and mtn snow will
increase over vtu/l.A. Counties later tonight and continue into sat
morning. Pcpn chances will diminish most area Sat afternoon, with
just the N slopes expected to have lingering rain and snow showers
sat night.

This system will not bring much rain to l.A./vtu counties, and
generally light to moderate rain to slo/sba counties due to the fast
movement of the system and lack of SE to S lower level flow which
would cause pcpn enhancement for areas S of point conception. It
looks like rainfall amounts should be about one quarter to one half
inch over slo/sba counties, with up to three quarters of an inch for
the nwrn slo county foothills. For l.A./vtu counties, a tenth of an
inch or less is expected, except locally up to 0.15 inch in the
mtns. Snow levels should lower to 6500 to 7000 ft by Sat morning,
with perhaps local amounts of an inch or two possible above 7000 ft.

Weak upper level ridging will move over SRN ca Sat night into sun,
altho by later Sun another E pac upper trof will approach the
central coast, with increasing clouds and a slight chance of rain
developing over nwrn slo county by late in the day. Otherwise,
partly cloudy skies can be expected for the second half of the
weekend.

The upper trof and dissipating surface cold front will move into ca
sun night then move slowly E on mon, with a broad NW flow aloft over
the forecast area. This system will bring a slight chance of showers
to slo county and the N mtn slopes Sun night, with some rain and
snow showers lingering mainly on the N slopes on mon. Precip amounts
from this system will be light and generally less than a tenth of an
inch where pcpn occurs.

Gusty NW to N winds will be possible over the sba county mtns and s
coast Sat evening, as well as along the N mtn slopes into the i-5
corridor. Winds may approach advisory levels at times. Even stronger
winds are expected across the mtns and sba county S coast mon
afternoon into Mon night as strong northerly pressure gradients
develop. There should be gusty NW winds along coastal areas as well
mon afternoon, especially the central coast. Wind advisories will be
possible for several of these areas Mon afternoon and Mon night.

Temps are forecast to turn cooler Sat before warming some on sun.

Highs will be several degrees below normal on sat, then be near
normal to slightly below normal overall for Sun and mon. Highs in
the warmest vlys and inland coastal areas will be in the mid to
upper 60s sat, and upper 60s to lower 70s Sun and mon.

Long term (tue-fri)
the ec/gfs are in generally good agreement with the synoptic scale
features Tue thru fri. The upper trof that moved thru the area mon
will slide E and thru the great basin to the SRN rockies on tue,
while at the same time an upper ridge builds into the E pac. Upper
ridging will persist over SRN ca on wed, then weaken Thu as an upper
trof moves into the pac nw. This upper trof is forecast to dive se
into the inter-mountain west Thu night and fri, with a broad
northerly flow over SRN ca.

Dry weather with mostly clear skies will prevail across the region
tue thru fri. The bigger weather story will be strong and gusty
winds at times, especially Tue thru Tue night and again Thu night
into fri, as a strong northerly gradient persists at times. This
will bring gusty northerly winds to much of the area, with gusty ne
winds possible over slo/sba counties night and morning hours. The
strongest winds should be over higher terrain especially along the i-
5 corridor and below and thru passes and canyons of slo/sba
counties. Gusty winds will also affect the antelope vly. Winds may
approach warning thresholds at times in some areas, but for now it
appears strong advisory level gusts should prevail in the windiest
locations.

Temps are expected to warm up considerably during the extended
period, with highs several degrees above normal for may areas on
tue, then peak at 5 to 10 deg above normal way from the immediate
coast wed. Temps should turn slightly cooler Thu and Fri but remain
near normal to several degrees above normal for much of the region.

Highs in the warmest vlys and inland coastal areas should reach the
mid 70s to around 80 on tue, low to mid 80s wed, and mid 70s to
around 80 Thu and fri.

Aviation 25/0130z.

At 00z, there was a weak marine layer at 900 feet and an
inversion at 4000 feet with a temperature of 12 degrees celsius at
the top of the inversion.

Moderate confidence inVFR conditions everywhere through at least
03z today. Weak cold front will move down the coast tonight. 90
percent chance of -ra at kprb ksbp ksmx... 60 percent chance at
ksba... And 30 percent chance elsewhere. MVFR CIGS are likely over
most places with the timing of the front... With a 30 percent
chance of brief ifr cats at kprb ksbp. 30 percent chance of MVFR
cigs forming as early as 05z ahead the front anywhere over los
angeles and ventura counties. Widespread gusty west to northwest
winds are likely Saturday afternoon with mostly cig-free skies.

Klax... High confidence inVFR conditions through 05z today. 30
percent chance of MVFR CIGS 06-12z... 60 percent chance 12-18z and
a 30 percent chance of -ra. No significant east winds expected
over next 24-hour period. Gusty west winds likely Saturday
afternoon.

Kbur... High confidence inVFR conditions through 03z today. 10
percent chance of MVFR CIGS 06-12z... 60 percent chance 12-18z and
a 30 percent chance of -ra.

Marine 24/130 pm.

There is a 60 percent chance for low-end small craft advisory
(sca) winds to 25 kt south of point conception late this afternoon
through much of tonight... Including the sba channel and santa
monica basin (inner waters). A weak front will also move down the
coast tonight, which will temporarily weaken the winds later
tonight into Saturday, but widespread gusty NW winds will form by
Saturday afternoon with most of the area needing a sca. There is
a 30 percent of localized gale conditions from point conception to
the channel islands.

These NW winds will increase each day through Monday night when
they peak. By Monday night, 70 percent chance of gale force winds
from the central coast to san nicolas island, with a 40 percent
chance for the inner waters. A persistent short period (6-8
second) swell will also likely persist through early next week
peaking Monday and Tuesday.

Lox watches/warnings/advisories
Ca... None.

Pz... Small craft advisory in effect from 3 pm Saturday to 3 am pdt
Sunday for zones 645-670-673. (see laxmwwlox).

Small craft advisory in effect until 3 am pdt Saturday for
zones 650-655-676. (see laxmwwlox).

Hazard potential outlook (mon-fri)
a weak weather system will bring some showers and mountain snow
showers to slo county and the north mountain slopes on Monday.

Gusty northwest to northeast winds will affect the area at times
Monday through Friday. The winds should cause some travel issues
at times during the period. Winds may be strong enough in some
areas for small trees or tree branches to be knocked down.

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.
