Update for new aviation discussion...

Synopsis
A trough of low pressure will bring cooler conditions for
Thursday and Friday with another round of gusty northerly winds. A
brief warmup is likely this weekend with ridge of high pressure
nosing into the region, before another trough brings cooler and
breezy conditions early next week.

Short term (tdy-sat)
a warm day across the area as high pressure combined with weak
offshore flow generated strong compressional heating. Although
below record levels, temps are still 10-20 degrees above normal.

Significant cooling, though still near to slightly normal,
expected Thu as a trough that is currently moving into northern ca
will shift the offshore flow to strongly onshore. So in addition
to the cooler temps we'll see strong west to northwest winds
developing in the afternoon, especially along the central coast,
srn sb county, all the mountains, and the antelope valley. High
wind watches were posted earlier for all those areas except the
central coast, which certainly will need advisories for tomorrow
as will much of the remainder of the area by late afternoon or
evening.

This wind event is expected to be on par with the event we had
Monday night into early Tuesday. Strongest winds at that time were
in the i5 corridor where gusts in excess of 80 mph were observed
at whitaker peak just above interstate 5. Will probably see
similar speeds Thu night. The advisory level winds will include
coastal la county where more gusty north winds are expected
through and below the hollywood hills.

Winds will remain gusty through Friday though below advisory level
after Friday morning. With the cooler air arriving with the trough
expect another few degrees of cooling Friday.

Then we bounce back up Saturday as gradients shift to offshore
and the northeast (santa ana) winds kick in. Might be a low end
advisory level santa ana event Saturday, though fairly brief as
upper support and gradients weaken late sat. Highs will jump a
good 5-10 degrees from Friday, pushing highs again well into the
80s for the valleys and near 80 for interior coastal zones.

Long term (sun-wed)
another pretty warm day Sunday, though likely a few degrees cooler
especially for coastal areas as offshore flow weakens. Models
continue to bounce around a little bit with the Monday trough.

Though virtually all solutions now are dry, the big question
remains how far south the trough will dig and whether we'll see
another burst of strong north winds late Monday into Tuesday.

Either way we should see another few degrees of cooling Monday,
then warming Tuesday/Wednesday as a ridge of high pressure
develops along the west coast and gradients turn weakly offshore.

Aviation 29/2355z
at 2255z, the inversion at klax was 100 ft deep. The top of the
inversion was at 1200 ft with a temperature of 22 deg c.

Generally hi confidence in the 00z tafs.VFR conditions are expected
at all the airfields thru thu, except there should be a period of
ifr/MVFR vsbys at kpmd and kwjf aft about 21z Thu due to blowing
dust. There is, however, the slight chance (20 percent) of low
clouds with ifr CIGS developing around klax and klgb aft about 12z
thru mid morning thu. Gusty NW winds will affect ksbp and ksmx thu
afternoon, with gusty W winds at koxr, kcma and klax, and gusty n
winds at kvny. Very strong W winds can be expected at kpmd and kwjf
late Thu morning thru the afternoon, with gusts up to 50 kt
expected, contributing to the reduced vsbys in blowing dust.

Klax... Generally hi confidence in the 00z taf.VFR conditions are
expected thru Thu evening. However, there is the slight chance (20
percent) of low clouds with ifr CIGS developing aft about 12z thru
mid morning thu.

Kbur... Hi confidence in the 00z TAF withVFR conditions expected
thru Thu afternoon.

Marine 29/200 pm

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
