Synopsis
A weak low pressure system will bring occasional high clouds through
Tuesday, along with some cooling Tuesday. Low clouds will increase
Tuesday night with the cooling trend continuing Wednesday. A low
pressure trough will bring some rain Wednesday night and Thursday.

Fair weather will return Friday, then a low pressure trough moving
through the western united states will bring a small chance of
showers Saturday followed by offshore flow and warming early next
week.

Discussion For extreme southwestern california including orange...

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

skies were mostly cloudy this evening due to high clouds. The
offshore flow is still continuing in a few areas, with a recent wind
gust of 33 mph from the east at highland springs. The closed upper
low was about 400 miles west of san diego, and this will track to
our south by Tuesday morning. This will continue to bring a lot of
high clouds, with some cooling aloft Tuesday, but precipitation
looks very unlikely, with no more than sprinkles.

Models continue to show a trough of low pressure reaching
northern central california Wednesday with its axis moving through
socal Thursday morning. The trough amplitude weakens considerably by
the time it moves through, though moisture will extend up to around
700 mb and combine with 15-30 knot onshore flow in the 850-700 mb
layer to bring some precipitation moving from northwest to southeast
through the forecast area Wednesday night and Thursday. Some
orographics will occur on west to southwest facing slopes. See
hydrology section below for more details, but generally 1 4 to 1 2
inch of rain is expected with up to 3 4 inch on coastal slopes.

Instability will be limited, so most of the rain will be stratiform.

Rainfall rates will likely remain below 1 4 inch per hour, with most
areas substantially less, so flooding and debris flows are not
expected in the recent burn scars. With most of the cold air staying
north of the forecast area, snow levels will remain at above 7000
feet during this system. An inch or two of snow could fall near the
highest peaks, but moisture will be limited above the freezing
level. Winds with this system will increase but generally be
moderate from the mountain crests to the desert slopes and into some
desert locations, with peak gusts mostly under 50 mph in windiest
locations.

The system should move east Friday, with mostly fair weather
prevailing under a brief period of zonal flow, albeit with
temperatures a little below normal in most areas. A system
originating in the gulf of alaska will move rapidly ese through the
great basin Saturday, and there could be a few showers here, though
chances look low. The main impact will be the building surface high
afterwards in the great basin which will produce offshore flow, most
likely of moderate strength Saturday night and Sunday, then probably
weakening Monday if a weak shortwave moves through the northwesterly
flow aloft. The ECMWF and GFS have a possible system around
Wednesday or Thursday of next week with small chances of
precipitation here, but much better chances over northern california.

Hydrology
The forecast rainfall across socal is not expected to produce any
heavy runoff or flooding at this time. Rainfall rates in general,
are expected to be one-tenth of an inch per hour or less at lower
elevations, and locally up to two-tenths of an inch per hour on
southwest-facing mountain slopes. Timing of best precipitation
should range from around 4-8 am over orange and SW san bernardino
counties to 8 am-noon over san diego county. Total precipitation
should be mostly one-quarter to locally one-half inch at lower
elevations, with up to 3 4 inch, possibly very locally higher, on
the southwest to west facing mountain slopes. Desert areas will
likely receive very little precip as the moist layer will be mostly
limited to below 10000 feet above sea level.

Aviation
200355z... Coast valleys... Low clouds will return to coastal areas
after 08z, with bases 1200-1500 ft msl and tops to 1800 ft msl. Cigs
are possible at coastal TAF sites between 09z and 16z Tue but
confidence in timing is low. Clouds will extend 15 mi inland locally
with vis 2-4 sm in fog and higher terrain obscured. Low clouds
become sct by 18z tue. Low clouds will return Tue night with higher
bases and greater coverage.

Mountains deserts... Sct-bkn above 20,000 ft with unrestricted vis
through Tuesday.

Marine
No hazardous marine weather is expected through Thursday. Wind gusts
near 20 kt are possible Friday into Saturday, mainly near san
clemente island.

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

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.
