915 pm pst Wed jan 23 2019

Synopsis
Fair weather will prevail through at least the middle of next week.

Occasional gusty winds from the northeast will occur mainly below
mountain crests, passes and canyons, with strongest winds Saturday
and possibly next Tuesday or Wednesday. Daytime temperatures will
average above normal.

Discussion For extreme southwestern california including orange...

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

Update...

tranquil weather prevails across socal tonight. Temperatures have
cooled faster than forecast and this trend looks to continue with a
dry airmass in place and light winds outside the santa ana wind
locales. Have lowered forecast temps for tonight by several degrees
at most locales. Ecmwfbc guidance looked to be a best fit.

A tranquil pattern will continue through at least the middle part
of next week. There will be periods of offshore surface pressure
gradient increases as shortwaves dive southeastward to our east.

This will lead to periods of santa ana winds of mostly moderate
intensity, one period thu-fri, another on sat, then yet another
next tue. None look too strong, though the period Saturday morning
could be the strongest. A wind advisory continues in effect
overnight-thu morning for wind gusts of 40-50 mph. Advisories may
be needed again for Friday morning.

Previous discussion (issued at 130 pm pst Wed jan 23 2019)...

sunny skies prevail this afternoon with low-elevation temperatures
mostly in the mid to upper 60s, and some stations should top 70
later this afternoon. Winds had decreased with all stations now
having gusts below 30 mph, mostly less than 15 mph.

High pressure aloft will prevail off the west coast through at
least the middle of next week, while most of the us will be under a
cold trough. Offshore flow will prevail as surface high pressure
continues over the great basin with 850 mb temperature differences
of 4-8 deg c between the NE and SW sides of the larger socal
mountain ranges. A bit of a cold air push over the great basin will
enhance the winds a bit Thursday, and a wind advisory has been
issued for some of the windier locations from orange county to the
san bernardino mountains from 4 am to noon Thursday. Short waves
Friday and especially Saturday will enhance the winds. Most of the
wind gusts at windier locations should be 40-50 mph Thu Fri but
could exceed 60 mph sat. The offshore flow and increasing temps
aloft, at least those west of the mountains, will bring mild weather
thu-sat with widespread 70s to near 80 at lower elevations.

A short-wave oriented east-west will likely move south across the
western us, including california around Tuesday and bring brief
cooling followed by enhanced offshore flow. Longer range model
output shows a possible storm system moving into the west coast late
next week, but confidence is low at this point as ensembles show a
wide range of solutions.

Aviation
240415z... Clear skies with unrestricted vis through Thursday.

Northeast winds may occasionally gust 15-20 kt at kont during
morning and early afternoon hours Thursday.

Marine
No hazardous marine weather is expected through Monday.

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

Sgx watches warnings advisories
Ca... Wind advisory from 4 am to noon pst Thursday for orange county
inland areas-san bernardino county mountains-san bernardino
and riverside county valleys-the inland empire-santa ana
mountains and foothills.

Pz... None.

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.
