104 am pdt Sun sep 24 2017

Synopsis
Gradually strengthening offshore flow will bring a warming and
drying trend with mostly clear skies to the area through next
week. There will be some gusty north to northeast winds at times
over the region, especially below and through passes and canyons.

Temperatures will be a few degrees above normal for many areas by
early next week, then increase to much above normal by late in
the week.

Short term (sun-wed)
a rather quiet evening on the forecast desk as we have a non-
existent inversion and no clouds across southwest california or
the coastal waters. Temperatures peaked out well below normal for
most areas for another day, but that will change tomorrow. Locally
gusty north to northwest winds occurring near canyons and passes
of the santa ynez range, but speeds are below last evening. Also
getting gusty winds over the san gabriel mountains and parts of
the antelope valley this evening. Expect winds to slowly decrease
during the night across south santa barbara county while across
western los angeles and eastern ventura counties northeast winds
will increase. A weak santa ana will make an appearance late
tonight and into Sunday morning and could make it briefly to the
oxnard plain and into the santa monica mountains. A few gusts
could exceed wind advisory levels (35 mph) across the moorpark to
simi valley area and near the 126 freeway, but gusty conditions
should not be widespread or long-lasting. Winds will shift back to
onshore in the afternoon. This will be the start of significant
warming and drying trend across the region. Temperatures will
rebound to near normal on Sunday with a few coastal areas possibly
pushing above normal before the seabreeze arrives. Some mountain
areas will see 15-20 degree temperature increases on Sunday
compared to today. A large upper trough over the great basin will
be reinforced by another low pressure system dropping into the
southwest states by mid-week.

***from previous discussion***
for Sunday morning, lax-daggett gradient expected to be around -3
mb, and could increase to between -3.5 and -4 mb range on Monday
and Tuesday mornings. Upper level wind support is fairly weak
on Sunday and Monday but could nudge up a bit by Tuesday Tuesday
night as models trending towards a closed low developing somewhere
in the deserts of southeast california. For the most part,
expecting winds to remain below advisory levels during the short
term, with gusts generally ranging between 30 and 40 mph in the
mountains (including the santa monicas), and between 20 and 30 mph
in the valleys.

The combination of gusty offshore winds along with warmer
temperatures, lowering humidities, and very dry fuels will bring
an extended period of elevated fire danger, with brief critical
fire weather conditions possible. Please see fire discussion below
for more details.

Long term (thu-sun)
long range models still showing potential for northeast winds
gusting between 30 and 40 mph across the mountains on Wednesday,
then offshore winds should diminish slightly for Thursday and
Friday. Despite the weakening of the offshore flow, temperatures
away from the coast are expected to continue climbing well into
the 90s on Wednesday and Thursday, with the potential for
isolated triple digit readings in the valleys by Friday. While
earlier model runs had suggested that next Saturday could bring
the warmest temperatures of the next 7 days with a slight
resurgence of offshore flow, the latest 12z ECMWF has thrown a
bit of a curve ball with a weak cutoff low digging down the
coast. If this solution were to verify, we would have to begin
a cooling trend for next Saturday, but for now, will ride the
course til we get some better model convergence. Also of note,
there will be some very warm overnight low temperatures in
the foothills and wind exposed locations.

Aviation
24 06z
at 06z at klax... There was no marine layer nor an inversion.

Overall... High confidence in taf. There is a 20 percent chance
of ifr conditions ksmx from 10z-14z.

Klax... High confidence in cavu taf. East winds will be less than
8kt.

Kbur... High confidence in cavu taf.

Marine
23 800 pm
confident in low-end small craft advisory (sca) level winds
continuing over the outer waters through tonight, especially
between point conception and san nicolas island. The western santa
barbara channel will also see low-end SCA winds this evening, but
should be localized and brief enough to not need an advisory. All
areas will experience a short-period chop from these winds into
Sunday. No expecting SCA winds through the middle of next week,
but afternoon and evening onshore winds will get into the 10 to 20
kt range everywhere starting Sunday with the warm conditions
inland. Pockets of dense fog cannot be ruled at times through next
week... Please stay aware of your immediate environment.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect until 3 am pdt early this
morning for zones 670-673-676. (see laxmwwlox).

Hazard potential outlook (wed-sun)
a prolonged period of elevated fire danger is expected Tuesday
through Saturday due to the combination of gusty offshore winds,
very warm temperatures, low humidities, and very dry fuels.

Brief critical fire weather conditions will be possible at times
especially in the mountains. There will be potential heat
impacts by Friday and Saturday as triple digit temperatures
are possible for warmest valley locations.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
