208 pm pst Thu nov 23 2017
High pressure aloft near the west coast and weak offshore flow will
continue to provide record-setting hot temperatures today for many
areas. The cooling will spread slowly inland Friday into the weekend
with greater cooling Sunday and Monday with stronger and gusty west
winds in the mountains and deserts. There is the potential for a
moderate strength santa ana wind event next Tuesday into Wednesday,
with the strongest and most widespread winds on Tuesday.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
very warm conditions across all areas today due to the combination
of light offshore flow and very warm high pressure aloft.
Meanwhilethe southern periphery of a high cloud shield is
affecting the northern portion of the CWA and could keep
temperatures from warming up much more there. Areas of san diego
county will still see several records tied or broken, with san
diego already tying the record high temperature of 86 degrees.
Offshore gradients are weaker today than compared to yesterday and
this morning, peaking ATTM about 6 mb from san diego to tonopah.
Offshore gradients will continue to weaken through Friday but
temperatures aloft will remain unseasonably warm and thus inland
temperatures will not see nearly as much relief from the heat
Friday as locations closer to the coast, where marine modified air
will help to cool things down considerably.
For Saturday through Monday, a troughy pattern will develop with a
weak frontal boundary and trough passage early Monday. Although
predicted moisture is meager there could be a few showers with the
front if it holds together by the time it gets to southern
california. Stronger onshore flow will bring strong gusty winds
through the passes and the desert slopes.
Another offshore pattern then develops for Tuesday through
Wednesday with a chance for near critical fire weather conditions
and abnormally warm temperatures west of the mountains.
232037z... P6sm vis and sct clouds AOA 20000 ft msl through about
24 0800 utc. 24 0800-1600 utc, there's a chance that dense fog low
stratus clouds (with bases 100-300 ft msl, tops around 500-700 ft
msl, and local vis of 1 4 sm or less) will develop within 5 sm of
the coast, possibly impacting ksan and kcrq, with lesser chances for
ksna. However, confidence in dense fog occurrence remains low at the|
moment. Otherwise elsewhere, p6sm vis and sct-bkn clouds AOA 20000
ft msl will continue.
No hazardous marine weather is expected through Tuesday except for
potentially gusty northwest winds to 25 kt over the outer waters
Elevated fire weather conditions will continue today for inland
areas with lowest humidities around 15 percent. Northeast winds
near the coastal foothills will be weaker than on Wednesday with
gusts mostly 30 mph or less this morning. Humidities will slowly
recover for Friday through the weekend.
For next Tuesday and Wednesday... A moderate strength santa ana
wind event is possible with lowest daytime humidities of 5 to 10
percent... And with the strongest and most widespread northeast
winds on Tuesday.
High temperatures forecast to be tied or broken today:

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. 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.
