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 29/1800z
at 1800z, there was no marine layer at klax.

High confidence in the current forecast through 09z. Very low
confidence for the los angeles coastal tafs after 09z. The big
question is whether ifr ceilings will make into klax and klgb late
tonight and with no sign of any clouds in the coastal waters, we
decided to hold off for now.

Even though Thursday evening is just outside of the forecast
period, there is a significant chance of a brief period of
northerly cross winds at klax for Thursday evening into very early
Friday morning. The most likely period for this activity will be
04z to 09z.

Klax... High confidence in the current forecast through 09z. There
is a 50 percent chc of ifr cig/vis after 09z.

Kbur... High confidence in the currentVFR forecast.

Marine 29/200 pm
across the outer waters... A combination of winds and seas will
keep small craft advisory conditions through at least Thursday
morning. Gale force winds are likely Thursday afternoon through
Friday.

Across the inner waters... Strong SCA winds will affect the
western portions of the inner waters on Thursday and Friday with a
40 percent chc of gale force winds.

for zones 34-35. (see laxcfwlox).
