Synopsis
A weak west coast trough will bring warm days and comfortable
nights with low humidity through Tuesday. A ridge of high pressure
building over the southwest will bring hotter days Wednesday
through Friday.

Discussion For extreme southwestern california including orange...

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

considerable coastal stratus is finally developing along the
coastal strip, especially in san diego county. Coastal gradients
are trending a little stronger onshore between 6 to 7 mb from san
diego to the deserts. There could also be some patchy fog along
the mesas and in the valleys. Expect the clouds will linger
through mid-morning and gradually retreat to the coast.

A shortwave trough over SW oregon today will dive SE across the
great basin through Monday. Temperatures through Tuesday will
trend a bit cooler across the region, with temperatures in the
inland valleys and high desert struggling to reach 90 degrees on
Monday, and even in the low deserts only around 100 degrees. The
very weak tail end of the trough will move across socal Tuesday
and Tuesday evening. A period of gusty offshore winds could occur
Tuesday as well due to transitory surface high pressure over the
great basin, likely to be a weak offshore period.

For Wednesday through Friday, a blocking pattern will setup over
the east pac, with an upper level ridge sandwiched across much of
california. This feature will bring a gradual warmup during this
period with temperatures in the mid 90s in the valleys and high
desert and about 105 to 110 in the lower deserts.

For next weekend the models do project some disagreements but in
general the upper level trough from the eastpac block will begin
to eject into N ca and or. Temperatures should moderate back
closer to near-normal levels for the end of september. Even with
that trough precip chances look very meager although there could
be a bit of precip over N ca and or in closer proximity to the
upper trough. For socal the trough could bring a period of gusty
onshore winds but not looking like much else in the sensible wx
department.

Aviation
230920z... Coast valleys... Areas of low clouds slowly increasing in
coverage at this hour. Bases are around 1000 ft msl with tops to
1500 ft msl. Low clouds are expected to spread 10-15 miles inland
and impacts at ksan and kcrq are expected at times through 16z, but
impacts at ksna are doubtful. Patches of fog with vis 1-3 miles are
likely on higher coastal terrain. Expect clearing to the coast 16z
to 18z. Low clouds should increase in coverage again after 07z mon.

Otherwise, sct-bkn clouds at or abv 7000 ft msl through this
afternoon.

No hazardous marine weather is expected through Thursday.

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.
