Synopsis
Cooler weather is in the forecast through Friday as a weak trough
of low pressure moves through the region. Low clouds will spread
farther inland each night and morning as the marine layer deepens,
and strong and gusty winds will occur in the mountains and
deserts starting late this afternoon. The trough may create patchy
drizzle in the coast and valleys tonight into Thursday morning
and scattered light showers over and west of the mountains late
Thursday night through early Friday morning. High pressure aloft
will rebuild over the west this holiday weekend for warmer weather
and a shallower marine layer. Another cooling trend likely to
begin next Tuesday as another trough develops near southern
california.

Discussion For extreme southwestern california including orange...

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

marine layer stratus has diminished for the most part this
afternoon according to visible satellite, with scattered alto-
cumulus clouds moving overhead from the southwest throughout
southern california. These alto-cumulus are associated with a
short-wave trough, which can be seen on water vapor satellite
imagery moving northeast over central california. A low can also
be seen far offshore of central california, with a stronger trough
over british columbia and a weakening ridge over southern
california. The 12z miramar sounding shows an 11 deg c inversion
at around 1500 feet msl. Onshore flow is strengthening quickly,
with san diego to las vegas onshore pressure gradients up to 10.8
mb, whereas they were 2.2 mb at this time yesterday. Despite the
strengthening onshore flow and strong inversion, stratus managed
to clear at the beaches today. Today through early Thursday, the
trough over british columbia will push south and start to pull the
low far offshore of central california towards the california
coast while the aforementioned short-wave trough continues to move
northeast into the great basin. This increased troughing in
california will serve to further weaken the ridge over us and
continue to increase the onshore pressure gradients, resulting in
strong and gusty west winds along the mountain ridges, desert
slopes, through the passes and into adjacent desert areas
beginning late this afternoon. Wind gusts of 55 mph and local
gusts of 65 mph will be possible in and through the san gorgonio
pass and in the san diego county deserts, where wind advisories
have been issued. The lowering 500 mb heights and onshore flow
will also deepen the marine layer and bring a cooling trend for
all areas today and Thursday, with highs dropping to several
degrees below normal on Thursday. Temperatures currently are 5-15
degrees below what they were 24 hours ago over much of the region.

Expect marine layer stratus to move completely fill the coast and
valleys tonight into Thursday morning with patchy drizzle
possible.

As the low moves into southern california Thursday night into
Friday morning, it weakens into a short-wave and will bring
another burst of strong and gusty winds to the mountains deserts
and further deepening of the marine layer, with stratus Thursday
night Friday morning filling the coastal basin and moving into
the coastal slopes and passes. Large scale and hi-res models show
some very light precipitation being generated over and west of the
mountains late Thursday night into early Friday morning, resulting
in scattered 0.01-0.05 inch amounts.

The trough will move to our northeast by Friday afternoon, with
the cooler air mass resulting in highs 10-15 degrees below normal
Friday. For Saturday through Monday, an upper level ridge to the
west will move in and strengthen, creating a warming trend and a
shallower marine layer. Highs are likely to reach back to normal
to slightly above normal levels on Sunday and then 5-10 degrees
above normal on Monday. Expect night and morning marine layer
stratus over coastal areas and western valleys during this period.

For Tuesday through late next week, the GFS and ECMWF now show a
closed low (possibly of the cut-off variety) developing near or
south of southern california. This would likely bring cooling.

However, models don't show any precip associated with this low at
the moment.

Aviation
242021z... Coast valleys... Sct-bkn low clouds with bases 1000-1500
feet msl with tops to near 2000 feet msl over the coastal waters
will extend inland after about 25 03z this evening... Reaching inland
to kont and krnm by about 25 08z tonight. Areas of vis 3-5 sm over
higher coastal terrain and down to 1sm on coastal mesas western
valleys. Stratus clearing back to near the coast midday Thursday.

Moderate risk of bkn low clouds at ksan is now backed off to around
25 03z so confidence in bkn low cloud return at that time is
moderate.

Mountains deserts... A few high clouds and unrestricted vis. Onshore
winds becoming strong after 00z this evening with gusts through the
mountains and along the desert slopes up to 45 kts along with
moderate up downdrafts... And patchy blowing dust sand in the
deserts.

Marine
No hazardous marine weather is expected through Sunday.

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

Sgx watches warnings advisories
