Update
At 7 pm, fog satellite showed patchy stratus starting to develop
along the northern baja coast. Surface observations showed
temperatures 5-20 degrees higher than they were at this time
yesterday. Patchy low clouds will develop along portions of the
coast and coastal valleys tonight, with a few areas of fog. No
changes needed to the forecast this evening.

Synopsis
Tranquil and warmer weather conditions will prevail across
southern california through the upcoming weekend. The marine
layer and weak onshore flow will keep coastal temperatures near
average with areas of night and morning low clouds and fog. For
Tuesday through Friday... A low pressure system over the eastern
pacific will move slowly towards the west coast. This will bring
slowly increasing onshore flow and slow deepening of the marine
layer with night and morning low clouds and fog extending into
portions of the valleys. Slow cooling will spread into the valleys
with periods of gusty southwest to west winds in the mountains
and deserts.

Discussion For extreme southwestern california including orange...

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

Prev discussion
The overall weather pattern through the weekend will feature dry
and warm conditions across the area. The overall pattern features
a departing upper level low to the east with heights rising
locally. An upper level trough will move south of the area this
weekend with no consequence. The result will be warm temps
continuing through the weekend along with dry weather conditions.

Marine layer cloudiness and fog is forecast to develop over the
ocean tonight with some clouds and perhaps fog moving in towards
dawn on Saturday. However, confidence in fog is low at this time
with little marine layer stratus even west of the islands.

The pattern next week will feature an upper level trough moving
slowly towards northern and central california. Southwest wind
flow ahead of this trough will result in a more inland penetration
of nighttime and morning marine layer cloudiness. However, it
looks as though southern california will remain under tranquil
conditions. Winds could pick up in the mountains and deserts as
this trough finally moves onshore the norcal coast next fri-sat
along with slightly cooler temperatures.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
