Synopsis
High pressure aloft will keep the weather fair, dry and mild this
weekend. Monday will be cooler with more clouds. There is a small
chance of light showers along and west of the mountains Monday
afternoon through Monday night as a trough passes to the
northeast. A strong ridge will build in behind the trough with
fair and much warmer weather Wednesday through Friday. High surf
will pound the beaches Monday and Tuesday.

Discussion For extreme southwestern california including orange...

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

Highlights
* high surf will pound the beaches Monday-Tuesday
* few light showers coast to mountains Mon afternoon-night
* warming temperatures mid-late week, peak warmth on Thursday
an overall tranquil weather pattern will continue leading into
christmas with temperatures running above average.

A pacific storm will move into norcal tonight-Sunday with the tail
end moving across socal late Monday. Tranquil weather will
continue ahead of this feature. Marine layer stratus is possible
late tonight-early Sunday near the coast, but more likely Sunday
night. Dry weather will prevail with temps near slightly above
seasonal norms.

The atmospheric river ahead of the storm will be dwindling as it
move southeast. A formidable river of high moisture will impact
norcal, but by the time it arrives here, it will weaken
drastically from ivt of 500+ kg m S to less than 200 down here.

Precipitable water values are currently registering just under
0.50 inches locally and are forecast to only rise to 0.60-0.70
inches briefly Monday evening. So moisture is lacking with this
system this far south. The result will be the potential of only
isolated light showers with moisture profiles leading us to
believe any light showers will be from the mountains to the coast
(with less than a tenth of an inch forecast where it rains). Snow
in the mountains is forecast to be just a dusting where a snow
shower moves by.

An upper level ridge will pump up into california behind this
storm. This will be a strong ridge with h5 heights on both GFS and
ecmwf rising to 588-589dm by Thursday afternoon. The result will
be substantial warming during the second half of the work week
ahead with the warmest days Wednesday-Friday and likely the
warmest day occurring on Thursday when some 80-degree readings are
expected across the coachella valley, inland empire, inland
orange county and inland san diego county. This is 10-15f degrees
above averages for mid december. Surface pressure gradients will
be offshore as a surface ridge builds into the great basin with
offshore gradients strongest wed-thu, but this looks to be a weak
santa ana with gusty winds of 30-40 mph forecast at the windiest
locations below mountain passes and along the coastal mountain
slopes.

The ridge will break down next weekend and leading into christmas.

However, the pattern is such that the major pacific storms will be
too far north, impacting the pacific northwest with southern
stream energy shown in the global models to pass south. This means
that there is a likelihood of tranquil weather prevailing and
temperatures will continue to run above average.

Aviation
152145z... Mostly clear skies with mostly unrestricted vis will
prevail through Sunday. There is a chance of patchy bkn low
stratus fog within 10 miles of the coast late tonight and early
Sunday, with CIGS 600-1000 feet msl. Most likely time of coverage at
coastal airports is 11z-15z sun.

Marine
No hazardous marine weather is expected through Sunday. A large wnw
swell Monday and Tuesday will likely generate combined seas of 10-13
feet in the outer coastal waters. Swell and seas will lower
Wednesday.

Beaches
A west-northwest swell of 10-13 ft at 18-20 sec from 290 degrees is
expected to arrive Monday and continue through Tuesday. Surf of 6-11
feet with local sets to 13 ft or more will be possible, highest
south of del mar. Strong rip currents and dangerous swimming
conditions are likely at all beaches. A high surf advisory is in
effect from Monday morning through Tuesday evening. Swell and surf
will gradually lower on Wednesday, though another swell could bring
elevated surf around Friday.

Skywarn
Skywarn activation will not be needed this weekend.

Sgx watches warnings advisories
Ca... High surf advisory from 8 am Monday to 10 pm pst Tuesday for
orange county coastal areas-san diego county coastal areas.

Pz... None.

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.
