Synopsis
High pressure aloft will weaken gradually through the upcoming
weekend, allowing the marine layer to build inland, with morning low
clouds and fog spreading farther into the valleys. It will be
slightly cooler each day through Sunday, as the deserts remain hot.

For Monday, a low pressure system will move inland, bringing greater
cooling, stronger and gusty west winds over the mountains and
deserts, and a chance for showers. Even isolated thunderstorms are a
possibility.

Discussion For extreme southwestern california including orange...

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

evening update:
no changes were needed to the forecast this evening. Gradients
continue to trend weakly onshore. The 00z inversion has weakened a
bit according to the latest miramar sounding. Low clouds have been
slowly filling into the coastal basin this evening. Light fog likely
to occur late tonight and Friday morning, especially for inland
areas and mesas where the low clouds interact with terrain.

Previous discussion, issued at 122 pm pdt:
at 1 pm pdt... Marine clouds had retreated back offshore, except for
a few spots along the immediate coast. The sfc pressure gradients
were still quite weak and winds light most areas. Most reporting
sites had temperatures with in 3f of where they were yesterday at
the same time. A weak shortwave trough skimming the northern
portions of the CWA is firing up some cumulus over the san
bernardino mts. At this time, the short-range, hires models show no
precip developing so pops remain below threshold.

The broad upper-level ridge over the SW will slowly weaken through
the upcoming weekend, allowing the onshore flow to increase and the
marine layer to build farther inland. Little change is expected
tonight, but greater coverage into the valleys is likely by Sunday.

It will stay quite warm far inland and in the deserts until then,
but for the western valleys incremental cooling is expected each day
as the sea breeze strengthens a bit more.

For Monday and Tuesday, expect more noticeable cooling as onshore
flow increases and daytime highs remain well below normal. This will
be in response to low pressure moving inland across socal. The
gfs ECMWF operational runs still show significant timing
differences, but the track and intensity of the system are very
close. This lowers confidence in any precip timing, which impacts
pops, which are spread out between Mon tue. Also, the pattern
suggests a threat of thunderstorms as we are placed in the ne
quadrant of the incoming system where lift should be maximized.

As the storm system moves east, models show another broad trough
building south over the west, which should maintain onshore flow,
the marine layer, and near to below average temperatures.

Aviation
260330z... Coast valleys... Status with bases 900-1100 ft msl along
the immediate coast will spread 10-15 mi inland overnight. Bases may
locally lower to 500-800 ft msl with areas of vis 2-5 sm in br hz
after 09z. Far west portions of the inland empire, including kont,
may have sct clouds below 1000 ft msl and vis 3-5 sm 11-15z. Clouds
will clear back to the coast between 16-19z. Stratus redeveloping
and spreading back into the coastal areas after 27 00z with bases
1000-1300 ft msl.

Mountains deserts... A few high clouds AOA 20000 ft msl and
unrestricted vis through Friday evening.

Marine
No hazardous marine conditions through Sunday. On Monday a trough
will bring a chance of showers and a slight chance for
thunderstorms, with showers possibly lingering into Tuesday.

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