Synopsis 19 525 pm.

Mostly cloudy skies with scattered showers and a slight chance of
thunderstorms will continue through late this evening, with
gradual clearing expected overnight. Monday will be breezy and
mostly dry, with a chance of lingering showers and snow in the
mountains. Showers will be possible again on Tuesday, with cool
temperatures expected through much of the coming week.

Short term (sun-wed) 19 739 pm.

***update***
a cold front that swept across the region earlier today has moved
well south of the area this evening. The upper closed low
associated with this storm is currently over central california,
and will shift to the south and east toward las vegas overnight.

Very cold air aloft (500 mb temperatures near -25 c) is providing
good instability scattered shower activity and the potential for
thunderstorms over areas north of point conception. Scattered to
isolated showers are also noted over portions of ventura and l.A.

Counties. The forecast has been updated to reflect a slight
chance of thunderstorms over slo sba counties and the coastal
waters north of point conception. In addition, the NAM shows an
impulse within the main upper low moving SE across the interior
forecast area. This feature has the potential to produce more
organized showers along the central coast, with additional
showers over the northern mountain slopes later tonight. Snow
accumulations up to 3 inches will be possible over 5000 feet in
the north slope area.

Rainfall totals so far have been variable, but the highest
accumulations have been north of point conception, with 1 to 2
inches of rain reported. Over ventura county, the mountains have
received up to 1.5 inches, with 0.25 to 0.50 inch over the coast
and valleys. Most areas in l.A. County have received between 0.20
and 0.60 inches, with the highest totals in the mountains and
some areas in the antelope valley.

***from previous discussion***
skies should begin to clear out early Monday, with some clouds
hanging around the foothill and mountain areas into the
afternoon hours. There will be enough northerly flow late tonight
into early Monday for clouds to bank up against the northern
slopes of the ventura sba county mountains and a few showers or
light snow falling to around 5500 ft to continue in the early
morning hours. High temps should rebound some on Monday with highs
still well below normal for this time of year. Expect most areas
away from the mountains to be in the mid 60s to lower 70s.

By Tuesday, another negative tilted upper low swings into northern
cal and nevada. The models are indicating enough lift along the
western peripheral that additional rain showers will be possible
across areas N of point conception and possibly along southern
l.A. County. This does look more like an inside slider however. There
will be increasing northerly winds across the sba vtu sba
mountains and antelope valley Tuesday night as stronger northerly
winds move across the region. The surface gradients remain mainly
nw to se, but there will be enough upper level support that
should allow cold air aloft to mix down to the surface and bring
widespread gusty northerly winds into the wind favored coast and
valleys. Additional wind advisories might be needed for these
areas. High temps are expected to drop 3-6 degrees with the inside
slider moving into nevada.

For Wednesday, broad northerly flow aloft will prevail as a 591 dm
high builds across the eastern pac. Both the GFS and euro models
keep the upper low nearly stationary over southern nev az.

Therefore gusty northerly winds are expected to continue.

Widespread warming 2-5 degrees is expected but will once again
remain cooler than normal for this time of year. Skies should be
mostly clear except for some partly cloudy skies across the
mountains and interior locations of slo sba counties.

Long term (thu-sun) 19 233 pm.

This unseasonable weather pattern will continue through late into
next weekend. Both the GFS and ECMWF continue to hold onto this
meridional upper level pattern. The upper high will remain
stationary across the eastern pacific while the upper low over
nevada fills in but a trough will continue to remain over the
southwestern states through Saturday. Another upper level
disturbance will work it's way down from oregon into northern
california or central california depending on which model is more
in line at the time. Nevertheless, the upper low will remain over
central california on Saturday and with no over water trajectory,
will not be tapping into much in the way of moisture. The cool air
aloft will destabilize the atmosphere and this combined with
short waves running around the upper low will provide for a chc of
showers over the area ESP over the mtns.

Max temps will continue to range about 10 degree below normal
through the period.

Aviation 20 0014z.

At 2300z at klax... There was no marine inversion.

Overall... Low to moderate confidence in the 00z tafs. Sct vcsh
across much of the forecast area through around 06z this evening,
with gradual clearing through 18z.VFR CIGS vsby expected but with
periodic lower categories (ifr-MVFR) possible through 06z. In
addition, there is a slight chance of tstms for l.A. County and
the ventura northern mountain slopes through 06z. Gusty sw-w winds
will affect portions of the area, strongest over kpmd and kwjf.

Klax... Moderate confidence in the 00z taf, with sct -shra
possible through 04z, and gusty sw-w winds through much of the
period. Any -shra that occurs could reduce flight categories to
MVFR.

Kbur... Moderate confidence in the 00z taf, with sct -shra
possible through 06z, and a 20% chance of tstms. Any storms that
occur could reduce flight categories to MVFR or lower.

Marine 19 739 pm.

For the outer waters... Small craft advisory (sca) level
conditions will develop this afternoon and continue through at
least Wednesday. There is a 30% chance of gale force winds Monday
night over pzz673-676, and a 60% chance over the same areas
Tuesday night. Large hazardous seas are expected through Wednesday
due to a combination of moderate period w-nw swell and wind waves.

For the inner waters north of point conception... There is a 40%
chance of SCA level winds Monday night through Tuesday night, and
a 30% chance Wednesday evening.

For the inner waters south of point conception... SCA level winds
and seas are likely to continue through late Tuesday night. There
is a 30% chance of gale force winds Monday night, and a 50%
chance Tuesday night. Steep hazardous seas will continue through
this time.

A slight chance of thunderstorms will continue over the waters
north of point conception through late this evening.

Beaches 19 527 pm.

A building NW to W swell will generate increasing surf along west
and northwest facing shores this week.

The largest surf will affect the central coast where a high surf
advisory is in effect through at least early Tuesday. The surf
will diminish on Tuesday but will remain close to or above
advisory level... Then increase again by Wednesday. It is possible
that the advisory may be extended through at least Thursday for
the central coast. A high surf advisory is also in effect for
Monday through early Tuesday for the ventura county beaches, where
surf of 5 to 8 feet is expected on west facing beaches.

A beach hazard statement will be in effect Monday through Tuesday

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
