.SYNOPSIS...

breezier late Tuesday into Wednesday, with some coastal clouds.

warmer weather Thursday and Friday. It looks much warmer with
stronger offshore breezes this weekend.

...UPDATED AVIATION DISCUSSION...

The showers ended last evening and skies have cleared out quite
cleanly early this morning. With clear skies in the valleys
allowing for maximum radiational cooling, there should be some
patches of ground fog early this morning to go with the chilly
temps, dipping into the 40s for many valleys. Skies today will be
quite sunny, but with increasing high clouds late today and
tonight. A trough of low pressure will move west to east to the
north of SoCal Tuesday into Wednesday. This will enhance onshore
breezes, especially for the mountains, deserts, and coastal waters
during this time, but only to around 25-30 mph. It will also
regenerate some marine layer low clouds for the coast and valleys.
Later Wednesday into Friday, high pressure aloft amplifies more
meaningfully, producing a noticeable warming trend for Thursday
into the weekend. With colder air occupying the interior West at
the same time, some offshore flow will develop for SoCal, but at
this time offshore winds do not appear strong or otherwise
problematic, especially through Friday. However, right now it
looks like the weekend could have stronger offshore winds, but
for now that is a low confidence idea. High temperatures through
Wednesday will continue several degrees below average for this
time of year, mostly in the 70s at lower elevations, low 80s for
the low deserts. Lows will be mild, actually a few degrees above
seasonal averages in the mid 40s and 50s. Highs and lows will
increase by the weekend, and the offshore flow will change the
distribution of the highest temperatures. That means lots of 80s
west of the mountains, even close to the coast. Some upper 80s
even look probable for inland coastal areas and western valleys,
if all goes to plan.

.AVIATION...
011030...VFR conditions expected through the period with mostly
clear skies through this morning followed by increasing clouds AOA
20kft this afternoon and evening. Weakly offshore winds will very
likely keep any low clouds offshore this evening and tonight.

&&

.MARINE...
Weak winds expected through Tuesday morning, followed by more
elevated onshore winds Tuesday afternoon and evening, with gusts in
the outer coastal waters potentially exceeding 20 knots.

&&

.BEACHES...
Southwesterly swell (3 ft at 15 seconds from 200 degrees) will bring
elevated surf through today, with breaking wave heights 3 to 6 feet.
Surf combined with a high tide near 6 ft will continue the potential
for minor tidal overflow during today`s high tide around 3:30 PM.

Tides are expected to increase for the end of the week, with tides
reaching 7 ft as early as Friday, bringing the potential for at
least minor tidal overflow even with little contribution from surf.
Tides will peak over the weekend into early next week around 7.5 ft.

Reminder, tides mentioned have been corrected to reflect the current
trends in actual tide observations.

&&

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