UPDATE. Updated air quality issues section.
SYNOPSIS. A cooling trend will continue over the next few days. Temperatures will run below normal through Tuesday. A few light showers and high elevation snow flurries will be possible over the mountains this evening. A heightened fire danger will exist over the mountains late tonight into Tuesday due to locally gusty winds and low humidity. A warm up is expected by the middle of next week.
DISCUSSION. Forecast looking on track. A digging trough from the north will move southward into the Great Basin and will merge over the area with a secondary weak trough to the southwest. This trough will bring a back door frontal boundary into central California from the north to northeast. Very little if any precipitation will accompany this frontal passage. At the most a few very light showers will be possible as the front moves through, primarily in the higher elevations. Behind the frontal passage very dry air and gusty northeasterly winds will move into the region and create very dangerous fire weather conditions for the Sierra Nevada and Kern County mountains and foothills along with the Kern County desert areas. Many locations in the desert and higher elevations will see relative humidities drop to the single digits. This drier air will help to efficiently radiate energy and overnight lows tonight and again Tuesday morning will be cool, with most locations about 5 degrees below normal levels. A few locations could be about 10 degrees cooler than normal with a few locations in the San Joaquin Valley and Kern County desert getting into the upper 30s. By early Tuesday morning the deepening trough will begin moving eastward toward the Texas panhandle region and eastern Pacific ridging will begin to move into the region. This will allow a warming trend to begin on Wednesday and temperatures will get near to above normal levels by the end of the week. By next weekend models look to bring another weak low pressure system into the region however confidence in exact timing and placement is not high at this time.
AVIATION. Local MVFR/IFR visibilities can be expected in smoke and haze over the Sierra during the next 24 hours. VFR conditions will otherwise prevail over the central California interior during this time.

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.

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 numerous 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.
