Cold tonight due to a dry, cold air mass and clear skies. Dry and
warmer for the weekend with locally gusty northeast winds near
the coastal foothills in the mornings and strong and gusty west
winds in the mountains and deserts Saturday evening. Another low
pressure system from the north will bring more showers with low
snow levels and strong and gusty west winds in the mountains and
deserts for late Monday night into Tuesday. Smaller chances for
showers for Wednesday and Thursday with increasing chances for
showers for Friday and Saturday.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
no major changes were needed this evening.
Offshore flow will develop tonight into Saturday morning as
surface high pressure builds in the great basin in the wake of the
departing trough, then turn briefly onshore Saturday evening
before turning back offshore Sunday. The offshore winds
tonight Saturday morning will be pretty weak, with local N to ne
gusts of 35 mph, but the turn to onshore winds Saturday evening
could be strong in the typical mountain ridges desert
slopes mountain passes and also the high deserts, and so a wind
advisory may be needed for those areas. The offshore winds for
early Sunday look mostly weak once again, with local gusts of
35-40 mph through below the passes canyons and into the coastal
foothills. Tonight should be pretty cold due to the cold, dry air
mass, clear skies and mostly weak winds. Temperatures are likely
to reach below freezing over much of the inland empire (except
below the cajon pass where gusty offshore winds surface), so a
freeze warning has been issued. Meanwhile, it may not get quite as
cold in the san diego county valleys and san gorgonio pass, so a
frost advisory was issued for those areas. The offshore winds and
weak ridging aloft building into the area will bring drier
weather and slight warming Saturday through Sunday. Highs may
reach near normal on Sunday west of the mountains, but still
colder than normal elsewhere.
Flow turns back onshore late Sunday night into Monday as a trough
digs down along the west coast. Models are in pretty good|
agreement with bringing this trough southern california Monday
night through Tuesday, likely resulting in widespread showers over
and west of the mountains and a few showers in the deserts.
Precipitation totals with this system do not appear to be too
heavy at the moment, with potential amounts of 0.10-0.50 inches in
the coast valleys, up to 1 inch in the mountains, and a few
hundredths in the deserts. This will be another cold system, with
snow levels falling to around 3500 feet and a few inches of snow
possible above that level. With the cold air aloft, instability
will increase, with the potential for some thunderstorms. This may
need to be added to the forecast soon. Onshore flow will
strengthen as well, with another round of strong and gusty west
winds in the mountains and deserts possible Tuesday.
The GFS and ECMWF have come into a little better agreement with
the 12z runs regarding another system for later next week, as they
both show a trough axis moving through northern california
Thursday with a cold front potentially bringing showers on late
Thursday and Friday.
240450z... Mostly clear with unrestricted vis through Saturday
Winds and seas will continue to decrease overnight, but it will
remain breezy over the weekend with northwest winds of 10-20 kt,
highest over the outer waters. A storm will bring more strong winds
and high seas Monday and Tuesday.
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

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.
