6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

915 pm pst Sun nov 19 2017
High pressure aloft along the west coast will bring unseasonably
warm weather this week. High temperatures will be 15 to 25 degrees
above average Wednesday and Thursday. Cooling will gradually spread
inland Friday through next Sunday as high pressure aloft weakens and
onshore flow returns.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
satellite imagery at 8 pm pst... Showed cirrus filaments drifting se
over socal this evening, otherwise the skies were clear. The
temperature column on the 00z miramar sounding indicated modest
warming and quite dry below 28k ft. The sfc pressure gradient
remained offshore at 7 mbs SW nv to ksan and about neutral to the
lower deserts. Winds were light.
It will be another very chilly night in wind-sheltered valleys, but
indications are it won't be as cold as last night. No changes to the
forecast this evening.
From previous discussion...
this morning started out cool in the wind sheltered valleys where
temperatures fell into the mid 30s at riverside and san pasqual
valley. In contrast, temperatures were some 20 degrees higher in the
windy areas like rancho cucamonga and fallbrook where the early
morning temperatures were 58f. The coldest air settled over the san
bernardino mountains and high deserts. Morning lows were in the
upper 20s and low 30s at victorville, hesperia and phelan, with the
coldest spots in the mountains at baldwin lake (13f) and the big
bear airport (14f).
The weather will turn warmer through Wednesday as 500 mb heights
steadily increase as a high amplitude upper ridge builds over the
southwest. This strong ridge aloft combined with weak offshore low
level flow will bring greatest warming Tuesday through Thursday with
highs in the 90s in the lower deserts and the valleys. Coastal zone
highs will be in the 80s, and mountain highs will be in the 60s and
70s. Both Wednesday and thanksgiving day will be exceptionally warm
days with record highs likely.
Friday through Sunday... The ridge aloft weakens and onshore flow
will return to southern california. Cooling will spread inland but|
temperatures will still be a little above average through next
200430z... Coast valleys... A shallow marine layer will create a small
possibility of fog along the coast tonight. Confidence is moderate
to high that coastal aerodromes will remainVFR. Otherwise, high
clouds and p6sm vis through Monday evening.
Mountains deserts... P6sm vis through Monday evening, with high
clouds at times.
Slight chance for patchy dense fog with visibility one mile or less
late tonight into Monday morning. Otherwise, no hazardous marine
conditions are expected through Friday.
There was still some very dry air in place today over eastern and
northern portions of the forecast area from the valleys to the
deserts where minimum rh fell into the single digits. A slight
recovery is expected over the mts through Tuesday. But drier
conditions will develop this week over the valleys and coastal
foothills as temperatures rise and offshore flow strengthens
By Wednesday into thanksgiving day, daytime high temperatures are
forecast to rise well into the 80s and lower 90s west of the mts as
east to northeast winds increase. The combination of very dry
conditions, near record high temperatures, and areas of easterly
winds 15 to 25 mph with gusts to 35 mph will create elevated fire
weather conditions, mainly along the offshore wind-prone areas of
the coastal foothills.
Conditions will slowly improve into the weekend as the offshore
weakens and the high pressure ridge aloft, subsides.
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

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.
