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 low pressure will alternate with weak high pressure this
coming week. Cooler with more coastal clouds this weekend, warmer
with less coastal cloudiness Monday through Wednesday, then
cooler with more coastal clouds later next week.

Discussion For extreme southwestern california including orange...

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

the coastal eddy we've got spinning out there is a textbook
specimen of what a coastal eddy should be. It has produced brisk
southerly winds along the coast, prevented clouds from clearing
in coastal areas (not just beaches), and even produced spotty
drizzle this morning. It is poised to push the clouds inland
early this evening to fill nearly all of the valleys overnight.

Temperatures at 1 pm are 3 to 15 degrees lower in all areas from
yesterday's temps at this time. The eddy and cooling trend come
courtesy of a low pressure trough moving through the interior
west. In addition, a tepid gulf surge brought dew points up and
temps down in the lower desert, insomuch that daggett in the high
desert is our unusual hot spot today at 105 so far. The coastal
eddy will continue into Sunday for a very similar day. The marine
inversion weakens a bit Sunday, so there should be just a little
more sunshine at the coast. High pressure aloft rebuilds Sunday
into Tuesday across the southwest, which will bring warmer weather
to all areas and a diminished marine layer. Coastal clouds will
probably not make it into inland valleys Tuesday through Thursday
mornings. Temperatures will head back above average inland on
those days. A low pressure trough will deepen in timid june
fashion across the west Thursday into next weekend. That will
reverse the trends, bringing down daytime temperatures and
extending the coastal clouds into the valleys each night and
morning. A weak trough and a weak ridge continue to jockey for
position over southern california next weekend, but the result
will be little variation around seasonal weather.

Aviation
232030z... Coast valleys... Stratus continues mainly along the coast
and 5-10 sm inland this afternoon with bkn-ovc bases ranging from
1500-2200 ft msl and tops 2500-3000 ft msl. Stratus will once again
move back inland this evening after 01z and spread into the valleys
with bases lowering to 700-1500 ft msl with tops to 2000 ft msl. All
coast and valley airports will likely be affected by the stratus.

Areas of vis 1-3 sm in br hz in the valleys between 10-17z Sunday.

Clearing to the coast may be a little quicker Sunday morning...

approximately 17-19z.

Mountains deserts... Mostly clear with unrestricted vis through
Sunday evening.

Marine
No hazardous marine weather is expected through Thursday.

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.
