Synopsis 20 728 pm.

Showers may linger over the area tonight, but otherwise conditions
should stay cloudy and dry. Another system will arrive Thursday
morning bringing a chance of showers and mountain snow. Dry
conditions are expected Friday and another chance for rain is
expected Saturday. Below normal temperatures are expected through
the remainder of the week.

Short term (tdy-sat) 21 310 am.

An upper low over monterey bay will swing a trof through the
central coast early this morning and will likely bring another
round of showers to that area. Elsewhere there will be partly to
mostly cloudy skies with a slight chc of showers as the trof
washes out overhead. The upper low will move to the SE during the
day and will reach kern county in the afternoon. A vort lobe
moving along with the low will create showers mostly over the
waters until the afternoon when it will move into la county this
afternoon and will likely create showers. As the cold air over the
upper low moves closer it will destabilize the atmosphere enough
to keep a chc of showers going over the mtns and slight chc
elsewhere. Rainfall amounts will be rather light except for la
county where up to a quarter inch of rain could fall. There really
is not enough dynamics or instability today to create showers
strong enough to bring dangerous rainfall rates. Enough PVA will
wrap around the backside of the departing low. Hgts will remain
on the low side today and along with moderate onshore flow max
temps will come in about 8 degrees blo normal.

A little ridge moves into the state on Friday. It is not that warm
a ridge and hgts only rise to 566 dm. Skies will be partly cloudy
as the ridge is not strong enough to prevent some mid and high
level clouds to sneak through. MAX temps will jump about 5 degrees
but will still come in blo normal.

The barest of trofs moves over the state on Saturday it does
little more than to knock down the trof. It will bring a chc of
showers to the central coast and the mtns. At this time it looks
too weak to bring any showers to the rest of the area. MAX temps
will cool 2 or 3 degrees and will end up 4 to 8 degrees blo
normals.

Long term (sun-wed) 21 326 am.

Another weak ridge moves into the state on Sunday. More
importantly some offshore flow develops. Skies will clear out and
max temps will rise about 5 degrees and most cst and vly locations
will have MAX temps a degree or two either side of 70. Still 2 to
3 degrees blo normal.

An upper low will move into the north of the state on Monday and
will push the ridge off to the east. Clouds will increase esp
over slo and sba counties, but it will remain dry over almost of
the area with the only chc of rain over the NW corner of slo
county. Despite the ridge moving off hgts will continue to rise
up from the south by a broad ridge that is also responsible for
the north track of the upper low. These higher hgts will lead to a
few degrees of warming ESP over the less cloudy vta and la
counties.

The upper low pulls more to the north and its associated front
does not make much in the way of eastward progress and the chc of
rain will be confined to slo and sba counties. The rest of the
area will see mostly cloudy skies. MAX temps will cool north of pt
conception but will not change much to the south.

The front finally makes its eastward push Tuesday night and
Wednesday. A chance of rain will develop over all over the 4
county area and persist into Wednesday afternoon. This really
looks like a late march system with minimal rainfall amounts and
rates. Hgts do collapse and along with overcast skies MAX temps
will roundly fall to 6 to 8 degrees blo normals.

Aviation 21 1113z.

At 11z, there was no marine layer or inversion at klax.

Expect areas of MVFR CIGS across the region through this evening,
with local ifr conds in the foothills and mountains. There will be
scattered showers through this evening. Expect conds to become
mostlyVFR tonight.

Klax... Low to moderate confidence in taf. Conds will vary frequently,
mostly between MVFR andVFR. There is a 20% chance of ifr conds
in occasional showers today. Expect mostlyVFR conds tonight.

Kbur... Low to moderate confidence in taf. Conds will vary frequently,
mostly between MVFR andVFR. There is a 20% chance of ifr conds
in occasional showers today.

Marine 21 358 am.

Moderate confidence in the forecast. Across the outer waters,
winds and seas are expected to remain below small craft advisory
(sca) levels thru Sat morning. However, there is a 30-40% chance
of SCA level NW winds and or seas this afternoon and evening. Sca
level NW winds are likely Sat afternoon into Sat night, possibly
continuing into sun.

For the inner waters north of pt sal, winds and seas will likely
remain below SCA levels thru Sat morning. However, there is a
20-30% chance of SCA level NW winds and or seas this afternoon and
evening. SCA level NW winds are likely Sat afternoon and evening
for the inner waters south of pt conception, winds and seas will
likely remain below SCA levels thru Sat morning. However, there
is a 30% chance of SCA level W winds and or seas this afternoon
and evening. There is a 40-50% chance of SCA level W winds
sat afternoon and evening.

Beaches 21 414 am.

A relatively large, long period west-northwest swell will slowly
subside today and surf should decrease below high surf advisory
levels by late afternoon. Another long period west-northwest swell
could bring high surf to area beaches again late Sat and sun.

Lox watches warnings advisories
Ca... High surf advisory in effect until 3 pm pdt this afternoon
for zones 40-41-87. (see laxcfwlox).

Pz... None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
