Synopsis
A persist trough of low pressure over the southwest states will
maintain below average temperatures into the middle of next week.

A storm from the north will bring showers into tonight and
Thursday with the most widespread showers along with a slight
chance of thunderstorms for this afternoon and early evening.

Another storm from the north will bring another round of showers
for Sunday into Monday, possibly lingering into Tuesday.

Discussion For extreme southwestern california including
orange... San diego... Western riverside and southwestern san
bernardino counties...

a persistent broad trough of low pressure will remain across the
southwest states through at least the middle of next week
maintaining below average temperatures.

There have been scattered light showers overnight. The greatest
coverage of mostly light rainfall amounts has been along the
coastal slopes of the mountains of san bernardino and riverside
counties and in san diego county along and west of the mountains.

Most amounts have been less than one tenth inch, but there have
been some amounts around palomar mountain in san diego county of
one quarter to one half inch.

Within this broad trough of low pressure, a cold low pressure
system from the north is moving through nevada and central
california early this morning and will move into southwestern
california today with the upper center moving into northwestern
arizona for early Thursday.

Scattered, mostly light showers will continue this morning, mainly
along the coastal slopes of the mountains of san bernardino and
riverside counties and in san diego county along and west of the
mountains.

The cold low pressure system from the north will bring more
widespread showers for this afternoon and early evening along with
a slight chance of thunderstorms. Given the convective nature of
the precipiation, amounts will be highly variable, but general
amounts will range from less than one quarter inch at the coast to
0.75 to 1.25 inch in the mountains with local amounts to around
1.5 inch. Hourly rainfall rates of around one half inch per hour
are possible with the stronger showers and isolated thunderstorms.

The snow level will be near 5500 to 6000 feet with an inch or two
of snow possible down around 5500 feet and amounts of 4 or more
inches mostly 7500 feet and above.

Showers will decrease from the northwest tonight, but could
linger for some areas along and west of the mountains through
Thursday morning and near the mountains for much of the day.

With the cooling from this low pressure system, high temperatures
for today in the mountains, deserts, and inland valleys will
generally be 20 to 25 degrees below average with some mountain
locations 35 degrees below average. Warming will begin for inland
areas on Thursday with greater warming on Friday but with high
temperatures for mountains, deserts, and inland valleys still
around 10 degrees below average on Friday.

For Sunday and Monday, additional low pressure systems from the
north will bring more cooling and showers, but with lower
confidence in the details as there is a sizable spread in the
details among the global models.

Those differences continue into the middle of next week as to the
degree to which low pressure may begin to weaken across the
southwest states. Some showers could linger into Tuesday.

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.
