Synopsis
Except for a slight chance of showers near the san bernardino
mountains this afternoon and Saturday afternoon, it will be drier
and warmer through Saturday. For Sunday into Monday, a low pressure
system from the north will bring cooling, stronger onshore flow with
strong and gusty southwest to west winds in the mountains and
deserts for Sunday into Sunday night, and periods of showers for
Sunday into Monday morning. Tuesday through Thursday will be dry
with a warming trend, but with temperatures remaining below normal
through next week.

Discussion For extreme southwestern california including orange...

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

moderate cumulus over the mountains this afternoon but no showers
have developed in our local mountains at this time, although there
are a few showers over nearby mountains and the mojave desert. Our
region will continue to experience fair weather conditions through
Saturday evening, under control of a baggy long wave trough over
the SW region. By Saturday night, an upper level low pressure
system will have dropped from the gulf of alaska into central
california, quite strong and cold for this time of the year,
strengthening into a 544 dm upper low near san francisco by
Saturday night.

Most of our model guidance is in agreement that the upper level
low will take a beeline across central california Sunday through
Sunday evening, with the best lift and cold air tracking just
north of our area across the southern sierra and mojave desert. As
has been the case with the last several storm systems, the
guidance has been slowly nudging further south with each run, and
since yesterday the consensus track has dropped a bit further
south, but still just to the north of our region. Sunday night
through Monday night, the upper level storm will gradually fill in
as the system ejects to the NE around the periphery of the large
upper ridge across the SE usa.

Even with the track differences in the forecast with some run to
run differences, we are still expecting an episode of widespread
but mainly light rain across our area, focused on Sunday afternoon
and evening. Snow levels will be the lowest across our san
bernardino mountains, and may require another late season winter
weather advisory above about 6000-6500 feet, where a few inches of
new snow will be possible. Rainfall amounts for the coast and
valleys will mainly be around one-tenth of an inch, with a few
spots around one- quarter of an inch, and up to one inch in the
favorable upslope (coastal slopes) of the san bernardino and riv
co mountains.

Onshore winds across the mountains and deserts will become strong
Saturday night, peaking Sunday and Sunday night when we will
likely need a wind advisory for the passes and along the desert
slopes. Little precipitation is expected in the deserts,
especially in the lower deserts and coachella valley, where the
biggest concern will be from the persistent gusty winds and
potential for airborne dust and sand problems.

Amazingly the baggy trough pattern looks to continue through much
of next week, with temperatures struggling to get even close to
normal levels for this time of the year (near 100 degrees in the
coachella valley for example). The GEFS and ecm ensemble means
favor the baggy trough for much of next week. Most models then
begin to introduce a strengthening east pac ridge by next weekend,
which would finally bring a break to all of the active weather
that socal has been experienced, with the potential for above
normal temperatures, well perhaps beyond next week!

Aviation
241950z... Coast valleys... Few low clouds with bases 1500-2500 feet

unrestricted vis this afternoon. Higher terrain obscured in
clouds fog at times. Mostly clear overnight.
