Synopsis
An upper level trough of low pressure will persist near the west
coast through Friday, maintaining onshore flow. Low clouds will
move inland each night into the valleys and clear back to near
the coast each day. Some drizzle is possible again tonight into
Wednesday morning. Slight cooling will spread inland through
Thursday followed by slow warming through the weekend into early
next week.

Discussion For extreme southwestern california including orange...

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

Update..

Satellite imagery this morning shows again shows marine layer
clouds extending into the inland valleys but the eastern extent is
eroding at this time. Like yesterday, the low clouds will erode
from east to west, but likely will remain along the beaches
throughout the day. Mid level clouds will continue to stream in
from the southwest associated with an upper level trough. These
mid level clouds will clear the area to the east by about
midnight. No changes were needed to the forecast. See previous
discussion below for further forecast details.

Previous discussion (issued at 310 am pdt Tue jun 25 2019)...

an upper level low pressure system is centered off the washington
coast early this morning. It will move slowly eastward to a
position along the pacific northwest coast for Thursday and
Friday. For the weekend, it will weaken and move northward. This
will maintain a trough of low pressure off the west coast through
Friday with southwest flow aloft and onshore for southern
california. As the trough weakens during the weekend, high
pressure aloft from the subtropical pacific, across northern
mexico, into the central great plains will expand northward into
southern california.

Early this morning, satellite imagery shows widespread low clouds
extending inland across most of the san diego county valleys and
continuing to spread into the inland empire from the west and
south. Satellite imagery also shows and area of mid and high
clouds ahead of a weak upper trough of low pressure over the eastern
pacific to the west of the california bight. These high clouds
will spread across southern california today, then move east
tonight.

Night and morning coastal low clouds will continue to spread
inland across most of the valleys into Friday, then not spread as
far into the valleys for the weekend into early next week as the
marine inversion lowers as high pressure aloft strengthens. The
low clouds did not clear some coastal areas Monday afternoon and
with a strong marine inversion and weak onshore flow, afternoon
clearing near the coast could continue to be limited and slow.

There is some patchy drizzle early this morning with a few
locations over northern san diego county and southern orange
county coastal areas reporting 0.01 inch of precipitation.

Slow cooling will spread inland today and Wednesday for coastal
and valley areas, and into the mountains and deserts for Wednesday
and Thursday with high temperatures a few degrees cooler. Slow
warming will then follow through the weekend into early next week
with high temperatures returning to around average.

Aviation
251615z... Coast valleys... Low clouds, with bases 1400-2100 ft msl

morning towards the coast, then linger along the coast throughout
the day, mainly in san diego county. Vis of 2-4 sm hz over inland
valleys will improve to p6sm by early afternoon. Stratus, with
similar tops and bases, will redevelop along the coast and push
into the inland valleys this evening and overnight.
