944 am pdt Thu sep 19 2019

Synopsis
Cool and breezy weather today will turn warmer this weekend as low
pressure over the west weakens. Gusty west winds will occur in
the mountains and deserts this afternoon and evening. Low pressure
will return next week, leading to a slight chance of showers
mainly in the mountains and desert Tuesday and Wednesday.

Discussion For extreme southwestern california including orange...

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

Update
Most low clouds over the valleys have cleared this morning, while
areas along the coast remain partly to mostly cloudy. Stratus may
linger a bit longer than normal this morning due to a coastal eddy
across the region. Previous forecast look on track, so no changes
needed this morning.

Previous discussion from 249 am this morning
A low pressure trough will move through the west today to give us
a cool day with MAX temperatures about 5-15 degrees below
average. Low clouds will have random and partial coverage anywhere
in the coastal basin tonight into Friday morning. Onshore winds
will increase this afternoon and continue through this evening in
parts of the mountains and deserts. Highest local gusts will
exceed 40 mph. The cold air moving into the western interior with
this trough will generate offshore flow, but offshore breezes from
the northeast will be confined to foothills and will not be
strong. Weak offshore flow continues Saturday and even into Sunday
as heights rise. That will bring a noticeable warming trend to
all areas, and serve to nearly eradicate any coastal low clouds
those mornings. Patchy coverage at most. MAX temps this weekend
will feature some 90s in the lower elevations, even getting close
to the coast. But it won't be strong enough for the beaches to get
out of the 70s. The next shortwave trough moves into the west
coast Sunday and Monday, drawing moisture northward out of mexico.

The moisture almost reaches california but it gets shunted off
into arizona before arriving. Yesterday's models had good
agreement or consensus, with this system becoming a cutoff low
over socal that would bring showers Monday through Wednesday
almost everywhere. Today's 00z models have good consensus too, but
they agree to bring the trough farther inland before cutting it
off over arizona, putting socal in the dry air for little if any
chance of showers. Consensus + consistency = confidence. We've had
good consensus, but bad consistency, so our confidence is low.

Our forecast has a slight chance of showers mainly for mountains
and deserts Tuesday and Wednesday. If the low spins over arizona,
socal would have some offshore flow, bringing clear skies, warm
days, cool nights, and some foothill breezes. If current trends
hold, that is the most likely outcome Wednesday and Thursday.

Here's hoping for some consistency to boost our confidence in next
week's forecast.

Aviation
191640z... Coast valleys...VFR conditions will prevail today. Patchy
low clouds will redevelop after 06z Fri and should make it 20-25 mi
inland overnight. Bases will be 1000-2000 ft msl. Low clouds
expected to scatter out by 17z fri.

Mountains deserts...VFR conditions today. Gusty W NW sfc winds from
the mtn crests eastward into the deserts, mainly after 18z. Expect
gusts 30-40 kt in the mtns, and up to 25-30 kt in the deserts. Llws
will be possible over and east of the mtns throughout the day, along
with mod uddfts.

Marine
No hazardous boating conditions are anticipated through Monday.

Fire weather
Locally strong and gusty westerly winds are expected this afternoon
and evening. Highest gusts will likely be 35 to 45 mph from the
mountain crests east through the desert mountain slopes and
through san gorgonio pass. Fortunately, humidity will increase
some, with mostly 10-20 percent in the deserts and 20-40 percent
in the mountains. The fire risk will still be somewhat elevated
from the mountain ridges east through the desert slopes.

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