Synopsis 18 321 am.

Warm and dry conditions will continue today. A storm will approach
the area on Tuesday... Clouds will increase and MAX temperatures
will fall. Showers are likely on Wednesday along with some
mountain snow and a slight chance of mountain thunderstorms. The
system will pull out on Thursday and skies will clear through the
day. It will be dry and warmer on Friday.

Short term (tdy-wed) 18 305 am.

Sunday's ridge will flatten out and move to the east today.

Onshore gradients will increase in the afternoon. This will lead
to several degrees of cooling across the csts vlys, especially
across the coastal plain, where MAX temps should be down 6-10
degrees, with 3-6 degrees of cooling in the valleys. MAX temps in
the mtns and deserts should change little or may actually inch up
a degree or two.

An upper low moving through the eastern pacific will approach the
west coast tonight and tue, with a trof extending southward.

The lowering hgts and cyclonic flow will spin up a batch of night
through morning low clouds to most coastal areas tonight and tue
morning. Later in the day mid and high clouds will push into slo
and sba counties. Onshore gradients will increase further, and
max temps will drop several more degrees in most areas. Any rain
from the approaching upper low and associated trough will likely
hold off until the evening.

On Tuesday evening the trof will take on a negative tilt and will
likely spawn a cut off low at its base just to the west of the
central coast. Showers will become likely across most of slo and
sba counties as the upper low approaches and a chance of showers
will develop vta and la counties in the SW flow moving up and into
them.

The low will then move eastward and over the southern san joaquin
vly on Wednesday. The weak PVA and somewhat unstable atmosphere
will likely bring showers to the entire area. During the afternoon
there will be enough cool air aloft to destabilize the atmosphere
over the mtns enough to warrant a slight chc of tstms. This chc
will last into the evening. This system does not have an external
moisture source so it will not produce that much rainfall
generally around a third of an inch... A little more over the
central coast and a little less over la county. Rainfall rates
will very likely remain under worrisome intensities. The SW flow
may well generate low end wind advisory gusts in the mtns. Max
temps will drop to 5 to 10 degree blo normals as the clouds and
low hgts work in concert to cool things off.

Snow levels will start out high at 6500 feet. Model solutions
agree that 700 mb temperatures will cool to near -7 degrees
celsius on Wednesday, but 850 mb temps will only fall to +2 to +4
celsius. Snow levels should drop to 5000 feet or so, which would
keep accumulating snowfall above the mountain passes such as the
grapevine portion of interstate 5 near los angeles-ventura-kern
county borders.

The low will pull out of the area Thursday. There is a slight chc
of a few showers over la and vta counties as well as the interior
vlys of slo and sba counties but these showers will not be very
much at all. Otherwise look for clearing skies and continued below
normal MAX temps.

Long term (thu-sun) 17 355 pm.

Models solutions start to diverge between Thursday and Saturday.

The ECMWF solution is a little slower with bringing the next
system in, while the operational GFS solution is a tad quicker. A
majority of the 12z GFS ensemble solutions have rain into the
central coast on Friday night, which agrees well with ecmwf
solutions. Pops have been nudged higher for late week and into
next weekend. Higher confidence in cooler and cloudier conditions
continuing for the period. Less confidence is pops and timing.

Aviation 18 1205z.

At 1200z at klax, there was a 700 ft marine layer. The top of the
inversion was around 2000 ft. With a temperature of 20 degrees c.

N of point conception... Moderate confidence with 12z tafs through
06z then lower confidence for coastal TAF sites in respect to
timing of vlifr ifr stratus. 40% chance for lower CIGS to develop
as early as 03z. Higher confidence for stratus to affect ksmx
compared to ksbp. High confidence with kprb 12z taf.

S of point conception... High confidence with 12z tafs away from
the coast. Moderate confidence for coastal TAF sites through 06z
this evennig. Then confidence lowers in respect to lifr ifr conds
for l.A. And vtu county sites. Higher confidence that ksba will
remainVFR.

Klax... High confidence in the 12z TAF withVFR conds thru 06z.

There is a 10-20% chance of stratus with ifr conds thru 16z.

There is a 20-30% chance that stratus will not materialize until
after 12z tue.

Kbur... High confidence in the 12z TAF withVFR conds thru the pd.

Marine 18 212 am.

For the outer waters, high confidence in the forecast thru tue
morning with winds and seas below small craft advisory (sca)
levels. By Tuesday afternoon into Tue evening, there is a 50%
chance for the northern zone (pzz670)for southerly winds
increasing to SCA level gusts. On Wed and thu, there is a 50%
chance of SCA level W to NW winds across the entire outer waters.

For the inner waters north of pt sal, high confidence in current
forecast through Tue night with winds and seas below SCA levels.

On wed, there is a 20%-30% chance of SCA level W winds, and for
thu there is a 30%-40% chance of SCA level W to NW winds.

For the inner waters south of pt conception, there is high
confidence that winds and seas will be below SCA levels through
tue night. On wed, there is a 30%-40% chance of SCA level W wind
gusts at times, and for Thu there is a 30%-40% chance of SCA level
w to NW wind gusts at times.

Lox watches warnings advisories
Ca... None.

Pz... None.

Hazard potential outlook (wed-sun)
High surf could affect west and northwest facing beaches
Wednesday. Rain is likely and gusty winds are possible with a
storm system moving over the region Wednesday and Thursday. Snow
could affect mountain passes Wednesday and Thursday.

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.
