Synopsis
Weaker offshore flow will prevail into the weekend with locally
gusty northeast winds near the coastal foothills at times and a
slow warming trend for inland areas. For Sunday into early next
week, offshore lower level flow will weaken further if not turn
weakly onshore. Cooling is expected to develop near the coast and
spread into the valleys. Patchy night and morning coastal low
clouds may return as early as late Saturday night into Sunday
morning.

Discussion For extreme southwestern california including orange...

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

Short term (today through Friday)
Closed upper level low pressure is centered over northern arizona
early this morning. It will weaken and move to the north and east
through Friday with another weaker upper low forming over the
southern california coastal waters on Friday as part of a
blocking pattern along the west coast. A few high clouds will move
southward across southwestern california this morning in the
circulation around the upper low centered over northern arizona.

Weak offshore flow will prevail through Friday with periods of
weaker northeast winds near the coastal foothills at times with
gusts mostly 35 mph or less. High temperatures will cool towards
the coast in orange county today with the weaker offshore flow
while most other areas will warm slightly today and Thursday with
a little more warming on Friday. The weak offshore flow may
strengthen slightly on Friday which would bring a little more of
the warming towards the coast.

Long term (Saturday through Tuesday)
The model trend in the past 24 hours for the extended portion of
the forecast is for the weak upper low off the southern california
to move slowly northward for Saturday into Sunday before weakening
and moving inland the Sunday and Monday. The main impact to
southwestern california of the northward shift of this weak upper
low is to shift to the north and east the axis of moisture
feeding into the upper low from the southeast and east. This
should reduce chances for any precipitation across southwestern
california though a slight chance is still retained for areas
around the san bernardino mountains for Sunday afternoon and
evening.

High temperatures will continue to warm a few more degrees on
Saturday for inland areas with not much change near the coast.

A weak upper trough of low pressure along the baja and southern
california coast on Sunday will weaken and move inland early next
week. This should further weaken the offshore lower level flow if
not turn the lower level flow weakly onshore. Some patchy stratus
may return near the coast as early as late Saturday night into
Sunday morning. Cooling will develop near the coast on Sunday and
spread into the valleys early next week.

Aviation
170900z... Mostly clear today and tonight, except for variable high
clouds across the interior this morning. Offshore winds mainly in
the foothills 15-25 kt with gusts 25-35 kt between 14-23z today,
with isolated pockets of llws and moderate up down drafts in lee of
mountain crests.

Marine
No hazardous marine weather is expected through Sunday.

Fire weather
Weaker offshore flow will prevail into the weekend with periods of
northeast winds near the coastal foothills at times with gusts
mostly 35 mph or less. Humidity for inland areas will slowly
recover through Thursday. Offshore flow might strengthen slightly
for Friday which would bring slightly stronger northeast winds
near the coastal foothills in orange and san bernardino counties
with slight drying. However critical fire weather conditions are
not expected on Friday, even with slightly stronger winds and some
drying. Offshore lower level flow will weaken from the weekend
into early next week if not turn weakly onshore at times. This
will bring a greater recovery in humidity with some cooling
spreading inland from the coast into the valleys for Sunday into
early next week.

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

Sgx watches warnings advisories
Ca... None.

Pz... None.

Public fire weather... 17

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.
