Synopsis for the far southern california coast.. At 2 pm, a 1017 mb high was along the central california coast, and a trough of low pressure extended north through the interior of california from a 1011 mb low near needles. Weak onshore flow will continue through Wednesday, strengthening Thursday through Saturday.

913 pm pdt Tue apr 24 2018
Fair and seasonal weather will continue this week, with areas of
night and morning low clouds and fog west of the mountains. Lower
pressure aloft this weekend into next week will bring cooler
weather, and extend the marine layer inland.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
at 8 pm pdt..Satellite imagery showed gathering stratus along the
coast as higher clouds thinned. Surface pressure gradients were up
to 8 mbs onshore ksan to the lower deserts but remained weak to the
ne and little changed from yesterday. Peak wind reports in wind-
prone areas of the mts deserts were in the 25 to 30 mph range. The
00z miramar sounding had a weak 4 degree c inversion based near 1200
ft msl. This was a few hundred feet below the weaker inversion
Based on the miramar sounding and other acars soundings, it appears
the marine layer inversion is near, or even a bit below where it was
last night. Also, the ridge over socal is holding fast. Because of
this we may again see some areas of fog forming just inland from the
coast and over the higher coastal terrain late tonight and Wednesday
morning. Grids and forecast zones have been updated accordingly.
From previous discussion...
heights gradually decrease Wednesday through Friday as the pattern
shifts with a trough developing over northern california.
Temperatures will remain above normal again Wednesday away from
the coast but look for significant inland cooling Thursday into
Onshore gradients will increase further and periods of gusty
onshore winds will be likely each afternoon and evening. Winds may
become strong enough to require a wind advisory by Friday. Much
cooler weather for Sunday through early next week. Upper level|
trough will swing by to the north on Friday and Saturday with
periods of strong winds possibly continuing into Saturday night.
Cooler conditions will continue through at least the middle of
next week as another upper level trough deepens over socal Tuesday
and Wednesday next week with very cool conditions over inland
areas and periods of strong winds possible. Still a lot of
disagreement with the strength of the trough but better consensus
that it could drop far enough south and with enough cold air aloft
to bring a chance of showers to portions of socal. Haven't added
any pops to the forecast yet until we have a little better run to
250400z... Coast valleys... Areas of bkn-ovc stratus along the
immediate coast will spread inland later tonight, reaching 10-20
miles inland by 09z. Bases will likely lower slightly from current
levels and be 600-900 ft msl with tops to 1200 ft msl. Areas of vis
2-4 miles with local vis below 1 mile will occur over higher coastal
terrain 07z-15z, and some coastal valleys could have local fog with
vis below 1 mile. Most areas will clear 16z-19z wed, with stratus
likely developing again Wednesday evening. Otherwise, sct-bkn clouds
at above 20000 ft msl will prevail through Wednesday evening.
Mountains deserts... Sct clouds at above 20000 ft msl with
unrestricted vis will prevail through Wednesday evening.
Stronger west to northwest winds will develop in mainly the coastal
waters beyond 30 nm each afternoon and evening Friday through
Sunday with gusts around 25 knots possible.
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
