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
Weak high pressure will alternate with weak low pressure in the
coming week. Hot inland weather will peak today, fade this
weekend, return early next week before some cooling arrives later
next week.

Discussion For extreme southwestern california including orange...

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

low clouds extended pretty far inland this morning for the kind of
high pressure we have pressing down overhead. That high pressure
has boosted temperatures in the desert today with the excessive
heat warning valid through sunset. So far (as of 1 pm) palm
springs and thermal have shot up to 109 degrees with no signs of
slowing down. A trough of low pressure moves slowly through the
interior west this weekend. That will help generate a coastal eddy
tonight, but the extent of clouds each night and morning will be
similar to this morning. Temperatures west of the mountains will
decrease a little, but mountain and desert temperatures will drop
5-10 degrees Saturday and an additional 5-10 degrees Sunday. It's
possible the marine inversion will remain strong enough to prevent
much beach clearing, but at least partial clearing is expected.

On Monday and Tuesday high pressure aloft builds over the
southwest again, but not to the level of the past few days. So it
will be warmer inland, but not dangerously hot. The marine layer
will be shallower and the nocturnal clouds confined closer to the
coast. Wednesday and Thursday the guidance shows a western trough
developing. So after a few more hot inland days early next week,
we'll get noticeably cooler weather for the latter half of the
week. The coastal low clouds will probably fill most if not all of
the coastal basin those nights. Small fluctuations in our early
summer weather pattern.

Aviation
222000z... Coast valleys... Low clouds with bases 900-1500 ft msl and
tops to 1800-2000 ft msl will spread inland this evening after 00z.

Areas of fog possible with visibility restrictions to 1-3 sm where
low clouds interact with coastal terrain and in some of the valleys.

Clearing to the coast will take place Saturday morning between 16-
18z.

Mountains deserts... Mostly clear with unrestricted vis through
Saturday.

Marine
No hazardous marine weather is expected through Wednesday.

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

Sgx watches warnings advisories
Ca... Excessive heat warning until 8 pm pdt this evening for apple and
lucerne valleys-coachella valley-san diego county deserts-
san gorgonio pass near banning.

Pz... None.

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.
