206 pm pdt Tue sep 18 2018

Fair, dry and slightly cooler weather is expected this coming
week. Areas of coastal clouds will continue nights and mornings.

Gusty winds will develop afternoons and evenings in parts of the
mountains and deserts.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino

tropical airmass slowly building north this afternoon across the
baja peninsula and gulf of california with some convection and
cumulus buildups noted in northern baja and into southern
arizona. Through Thursday most of the tropical moisture will get
shunted further east into arizona and new mexico. The best chance
for some of this moisture will be on Thursday. The GFS and hi-res
wrf models are even generating a few showers over our portion of
the colorado desert but that is probably overdone with lack of
forcing and thin moisture profile. There is better likelihood of
seeing an increase of low level moisture causing much higher
humidity east of the mountains and some low cloudiness at times

A shortwave trough will pass over socal tonight helping to
increase the onshore flow. Cloudiness should increase into the
western valleys late tonight. Westerly winds will become gusty
through the mountain passes and along the desert slopes this
evening through midnight or so. Winds may reach 50 mph at times
in the most wind prone corridors.

Later beyond Thursday the sprawling high pressure over the
southern plains will build east into the SE usa and cause the
tropical moisture to be shunted well to the east into nm and tx.

Much drier air will spread back over socal with the driest
conditions each afternoon and evening along with diurnally driven
gusty winds at times.

For early to mid next week, the medium range models are hinting at
developing offshore flow pattern with building high pressure over
the northern great basin by Wednesday behind an inside slider.

Right now the gradients do not look super strong but this would
prompt much warmer weather for areas west of the mountains than
we have been accustomed to for awhile.

182000z... Coast valleys... Clear with unrestricted visibility through
early evening. Bkn-ovc005-010 tops 014 forming at the coast between
02z-06z and spreading 15 miles inland through 15z Wednesday with
areas of vis from 3-5 miles at ksan, kcrq and ksna. Vis of 6 miles
in haze at kont between 13-18z. Skies will clear back to the coast
through 18z Wednesday.

Mountains deserts... Clear skies and unrestricted visibility through
Wednesday afternoon.

No hazardous marine weather through Saturday.

Fire weather
Near critical fire weather conditions will continue each
afternoon and evening in the mountains and deserts through
Wednesday with extremely dry air above the marine layer. Critical
conditions will actually be met for a few hours in pockets of
mountain passes and adjacent desert slopes this afternoon and
evening. Winds decrease and humidity gradually increases
Wednesday into Thursday.

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

Sgx watches warnings advisories
Ca... None.

Pz... None.

Public fire weather... Brotherton

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.
