San Clemente, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Strengthening high pressure aloft will bring warming through
Friday with the marine layer and weak onshore flow keeping
coastal areas cooler with areas of night and morning low clouds
and fog. For the weekend... A low pressure system moving through
the great basin will strengthen the onshore flow across southern
california deepening the marine layer and spreading cooling
inland. There will be slow warming for Monday through Wednesday as
the onshore flow weakens. Another low pressure system will move
to near the west coast bringing a cooling trend for late next
week.

Discussion For extreme southwestern california including orange...

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

strengthening high pressure aloft centered over northwest mexico
will bring warming through Friday. The marine layer has decreased
in depth to around 2000 feet with widespread stratus over the
coastal waters covering all of the orange county coastal plain and
extending inland into portions of the western valleys in san
diego county. With a strong marine inversion and weak onshore
flow... Clearing near the coast this afternoon may once again be
slow or limited. The marine layer will be a little shallower for
tonight into Friday morning with the coastal low clouds not
spreading as far into the western valleys.

For the weekend... A low pressure system moving inland through the
great basin will weaken the high pressure aloft over southern
california and strengthen the onshore flow. This will spread
cooling inland. It will also deepen the marine layer with coastal
low clouds extending into the western valleys on Saturday
morning... And into the inland valleys on Sunday morning.

For Monday through Wednesday of next week... The onshore flow will
weaken with slow warming and with the marine layer becoming
shallower. Another low pressure system moving to near the west
coast will bring a cooling trend for late next week.

Aviation...

210930z... Coast valleys... Stratus, with bases 800-1800 ft msl and
tops near 2000 ft msl, will continue this morning along the coast
and 15-25 sm inland. Vis of 3-5 sm br will also continue for most
inland valleys, with some areas less than 1 sm where low clouds meet
terrain. Low clouds will clear across inland areas by mid morning,
but will likely linger along the immediate coast throughout the day.

Stratus will then redevelop over the valleys again this evening,
with slightly lower tops and bases.

Mountains deserts... Mostly clear with unrestricted vis through
Friday morning.

Marine
No hazardous marine weather is expected through Monday.

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

Sgx watches warnings advisories

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.
