206 pm pdt Mon sep 16 2019

Synopsis
A trough of low pressure moving inland today and a second for
Wednesday will spread cooling inland with a return of night and
morning coastal low clouds and fog. There is also a slight chance
of thunderstorms into early this evening with little or no
rainfall expected. For Friday into next weekend, that second
trough of low pressure will weaken with warming trend.

Synopsis
A broad trough of low pressure aloft will generally remain over
the area through Thursday to keep temperatures below normal while
bringing a return of night and morning coastal low clouds and
fog. The trough moves east of the area by the end of the week with
a slight warming trend for the weekend.

Discussion For extreme southwestern california including orange...

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

the upper level trough axis has made its way onshore this
afternoon over northern california. This trough has cooled
temperatures over the forecast area as expected with current
temps 5 to 10 degrees cooler than this time yesterday. The
increasing onshore flow with this trough should also bring areas
of gusty winds to the mountains and deserts this afternoon and
evening. The other impact from this trough has been the increasing
onshore flow and mid level moisture that's brought some mid level
instability and a slight chance of thunder. Still some stratocu
moving across the area this afternoon per area web cams and
visible satellite imagery, but the lightning activity that was
west of the area this morning has been absent so far today. High
res models show any remaining instability fading away through the
day. Latest hrrr model still shows an area of very weak
instability making its way across the area later this afternoon
and evening. Confidence in any activity developing, even isolated,
is low. However am reluctant to remove the chances of
thunderstorms from the forecast. Emphasis is more on the very
slight side and primarily over the mountains and deserts this
evening. Any thunderstorms that do happen to develop will produce
little if any rain, rather will bring a threat of a dry lightning
strike or two and possible gusty winds.

The trough axis will be east of the area tonight and heights rise
ever so slightly on Tuesday, but thickness values hold steady to
bring little if any change in temperatures. Another upper trough
drops into northern california on Wednesday to cool high temps
another few degrees over southwest california on Thursday and
make it the coolest day of the 7 day forecast. Should also see a
return of the overnight coastal stratus and fog each night
starting tonight and really through most of the week.

Long range models agree on lifting Wednesday's trough into the
northern great plains on Friday or Saturday, at the same time a
tail of that trough hangs back to the southwest and extending to
the southwest of california. Heights still rise a bit even under
this extension and as a result Friday should start a weak warming
trend that will last into Sunday. Some differences in model
solutions out in day 7 whereby the ec drops another much deeper
upper trough over the great basin, but much less energy on the
gfs solution. Ec has jumped around a little bit from run to run
on this, so favor the GFS solution for little change from day 6 to
day 7 as opposed to the cooler and windier solution from the ec.

Aviation
161800z... Coast valleys... Sct-bkn mid and high clouds above 12000
feet msl. Isolated -shra possible until 00z. MVFR CIGS return after
04z tonight coastal terminals with sct-bkn MVFR CIGS for valleys.

Mountains deserts... Mostly bkn high clouds at above 15000 feet msl
with a slight chance of TS and CB bases above 10000 feet msl through
00z. After sunset sct high clouds.

Marine
There is a slight chance of cloud to water lightning this evening.

Otherwise, no marine weather hazards are expected through Saturday.

Fire weather
The upper level trough that has moved into northern california
will continue to move east tonight and Tuesday before a second
trough moves into the west coast on Wednesday. This will
strengthen the onshore flow with stronger and gusty southwest to
west winds in the mountains and deserts during the remainder of
this afternoon and evening. These gusty winds combined with lower
inland humidity will elevate fire weather conditions from the
desert slopes of the mountains into the deserts from mid afternoon
through early this evening and again Wednesday.

Some weak mid level instability moving through the area this
afternoon and this evening will bring a very slight chance of
thunderstorms to the mountains and deserts. Little or no rainfall
is expected. Any thunderstorms could produce gusty winds and a
few dry lightning strikes.

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