Synopsis
Cooler but dry weather will prevail this afternoon as a low pressure
trough moving by to the north combines with widespread high clouds.

Slight warming will occur over the weekend, but then more cooling
along with possible light showers will occur Monday and Monday night
as another trough moves by to the north. Another high pressure ridge
along with offshore flow and warmer weather will prevail in the
middle to latter part of next week. High surf is likely along the
coast Monday and Tuesday.

Discussion For extreme southwestern california including orange...

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

high clouds were streaming to the northeast ahead of a trough off
the northern central california coast. Temperatures were mostly in
the 60s to lower 70s at lower elevations. The high clouds will
continue through tonight before the trough moves east of the area.

After that, a moderate ridge of high pressure will occur over the
weekend and bring some warming. Local WRF shows some marine layer
moisture along the coast late tonight which could result in patchy
stratus, though nothing widespread. With the pressure height falls
of today, there should be some increase in the elevation of the low
clouds, versus last night which had a short period of fog along the
immediate coast. With the high clouds mostly shifted out of our area
to the northeast, and slight pressure height rises over the weekend,
at least inland areas should be a little warmer Saturday and Sunday.

The next trough of low pressure Monday will mostly stay to the north
with only a small amount of moisture aloft here. A few showers are
still possible but should produce minimal rainfall amounts, a few
hundredths of an inch or less. Some westerly winds will occur in the
mountains and deserts. After that, a ridge will move in from the
west and combine with offshore surface flow to bring more warming
and generally clear skies through at least next Friday. GFS solution
is warmer than ECMWF solution late next week as GFS has some 850 mb
temps as high as around 18 deg c, with GFS mos showing some temps in
the 80s in the valleys and even some areas 5-10 miles from the
coast, such as miramar or john wayne airport Thu fri. There could be
a trough the following weekend (dec 22-23) which could bring
precipitation.

Aviation
142120z... Sct-bkn clouds AOA 20000 ft msl and unrestricted vis
through this evening. Areas of sct-bkn low clouds with bases 600-
800 ft msl possible at coastal TAF sites after 08z Saturday,
however, confidence is low. Any low clouds that progress into
coastal TAF sites are expected to scatter out by 17-18z Saturday.

Marine
No hazardous marine weather is expected through Sunday. A large wnw
swell Monday and Tuesday will likely generate combined seas of 10-12
feet in the outer coastal waters.

Beaches
A west-northwest swell of 10-12 ft (in the outer waters) from 290
degrees with a period of 18-20 seconds is expected to arrive Monday
and continue through Tuesday. Surf of 6-12 feet with locally higher
sets is possible, highest in southern san diego county. Strong rip
currents and dangerous swimming conditions are likely at all
beaches. A beach hazard statement is in effect from Monday morning
through Tuesday evening.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

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.
