Synopsis
High clouds will prevail through Monday night, but otherwise fair
weather with temperatures slightly above seasonal normals will
prevail most of this week. Locally gusty northeast winds will occur
at times, mainly tonight and again late Tuesday through Thursday.

The jet stream will become more active over the pacific late in the
week and could bring increasing clouds and some precipitation next
weekend or early next week.

Discussion For extreme southwestern california including orange...

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

widespread high clouds were over the region tonight, and that will
continue through Monday night due to a long fetch of moisture
at above 500 mb upstream to our wsw. Local east to northeast winds
were occurring with a recent gust of 37 mph at highland springs in
riverside county, though most locations had light and variable
winds. Not much action is expected tonight through Monday night as
the high pressure ridge shifts to the east and a low-pressure trough
with most of its dynamics well to our north approaches. The weak
offshore flow tonight will switch to onshore flow Monday, but winds
will generally be light. That trough will move through the area
Tuesday, and current model guidance has no precipitation over us,
even though some increase in low-level moisture will occur. This
could produce some stratus by Tuesday morning in coastal and some
valley locations, but nothing major. With cooling aloft and some
marine layer activity, high temperatures will lower a few degrees
Tuesday.

Starting Tuesday, mostly weak offshore flow will develop in response
to a surface high forming over northern nevada, with wind gusts
similar or slightly stronger from those from today (mostly 40 mph or
less). Humidity will fall somewhat tue-thu, though with recent
rains, fire weather hazards will remain rather low. Some tightening
temperature gradients aloft could increase the offshore flow a bit
Thursday, but not much. Warmer weather will occur Wednesday and
Thursday due to little or no marine layer and warming aloft under
the transitory ridge. After that, a couple of troughs move by to the
north, with small chances of precipitation here, mainly Sunday. Most
model runs show the troughs bringing substantial rainfall to
northern california, but not here. A subtropical jet with larger
amounts of moisture (precipitable water > 1.5 in) will stay far
enough south over southern baja to not be able to interact with the
troughs.

Aviation
100415z... Bkn-ovc clouds at above 20000 ft msl with unrestricted vis
through Monday.

Marine
No hazardous marine weather is expected through Friday.

Beaches
A long-period west-northwest swell from 290 degrees will arrive
Monday, bringing elevated surf of 3-6 ft and strong rip currents
mainly Monday afternoon through Tuesday morning.

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.
