922 pm pst Fri feb 23 2018

Synopsis
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
counties...

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.

Aviation
240450z... Mostly clear with unrestricted vis through Saturday
evening.

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

Sgx watches warnings advisories
Ca... Freeze warning from 10 pm this evening to 8 am pst Saturday for
san bernardino and riverside county valleys-the inland
empire.

Frost advisory from 10 pm this evening to 8 am pst Saturday for
san diego county valleys-san gorgonio pass near banning.

Pz... None.
