Synopsis
Through tonight, a low pressure system will move slowly inland
across california and northern baja with a few showers this
morning and greater coverage of showers through the afternoon. Friday
will be dry and a little warmer, then another low pressure system
moving inland through northern and central california will bring
stronger and gusty southwest to west winds in the mountains and
deserts on Saturday with a small chances for light showers along
and west of the mountains. Sunday through Tuesday will be dry with
a warming trend with the next chance for precipitation around
Wednesday of next week.

Discussion For extreme southwestern california including orange...

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

Short term (today through Saturday)
Early this morning, radars show some lingering showers, mostly
over san diego county along and west of the mountains. The center
of upper level low pressure is to the west of point conception
with showers just of the central coast of california. As this low
pressure system moves inland across california today, this will
bring increasing showers across southwest california for this
afternoon with showers decreasing from the northwest this evening
and ending late tonight. Additional rainfall through this evening
will range from around one to two tenths of an inch near the coast
to one third to one half inch in the mountains with locally
greater amounts and with less than one tenth inch in the deserts.

The snow level will fluctuate between 5000 and 5500 feet with a
few inches of additional snowfall, mostly above 6500 feet. Gusty
west winds in the mountains and deserts will gradually diminish
through the afternoon.

Friday will be dry under weak high pressure. The next low pressure
system will move inland across northern and central california on
Saturday. This will bring stronger and gusty southwest to west
winds in the mountains and deserts with high temperatures a few
degrees cooler than on Friday. There will also be small chances
for light precipitation along and west of the mountains.

Long term (Sunday through Wednesday)
Sunday through Tuesday will be dry with a warming trend with
southwest flow aloft across california between high pressure
aloft over the rockies and a trough of low pressure over the
eastern pacific. High temperatures will warm to above average on
Monday and Tuesday. There will also be some high clouds at times.

On Wednesday and Thursday, the trough of low pressure will begin
to move inland into the western states with continuing differences
in the details among the global models. The current forecast uses
a blend, with increasing chances for precipitation centered
around Wednesday. As the trough of low pressure moves inland,
there will also be periods of stronger and gusty southwest to
west winds in the mountains and deserts.

Aviation 210900z... Coasts valleys... Variable sct-bkn clouds with
bases 2000-4000 ft msl will continue through this evening. Isolated -

clouds occasionally obscuring slopes. West sfc winds 15-20 kts
gusting to 35 kts over mountain crests, desert mountain slopes, and
through the passes today. Mod uddfts likely over and east of the
mtns at times. -shra unlikely to make it to kpsp ktrm, with sct
clouds based around 10000 ft msl.

Marine
No hazardous marine weather or seas are expected through Monday.

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.
