Synopsis for the far southern california coast.. At 1 pm, a 1012 mb low was over needles and a 1021 mb high was about 600 miles west of eureka. Tropical storm ivo remains about 725 miles south of san diego. Two to four foot swells from ivo should reach our coastal waters this evening and persist through Monday night before slowly subsiding. Weak onshore flow will continue through Wednesday with a coastal eddy at times.

Synopsis
High pressure aloft will bring warm weather and a shallow marine
layer through next week. Subtropical moisture is moving in from the
southeast and will bring scattered clouds, but no significant
rainfall is expected.

Discussion For extreme southwestern california including orange...

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

marine stratus was patchy both offshore and along the coast at 8 pm
pdt. Even the higher clouds evident were patchy over the deserts but
westbound. The 00z miramar sounding had 5c inversion based just
above 1500 ft msl. E-se winds of 15-30 kts dominate the column above
6k ft. Considerable moistening was evident around 12k ft. A very
weak inversion was present near 14k ft and it looked like any
convective level was above that. Basically a stable sounding, even
with an inch of precipitable water. Weak to moderate sfc pressure
gradients prevailed with mostly light wind reports.

Both the latest hrrr wrfems ECMWF want to pop a few thunderstorms in
the mts tomorrow afternoon. It may not be completely out of the
question, given strong heating and ample moisture, except the
atmosphere looks to be too stable, and moderate east winds in the
mid-levels will make it difficult for heated mtn top parcels to
develop vertically. No forecast changes.

From previous discussion...

heat spilled into valleys this afternoon where temperatures were 10-
15 degrees higher than yesterday. In the mountains and deserts, it
wasn't so much the heat, but the humidity. Moisture surged into the
mountains and deserts where dewpoints were 20-30 degrees higher than
they were on Friday. A low level moisture surge from the southeast
brought scattered low clouds to the lower deserts this morning, a
somewhat rare phenomenon.

There will only be minor changes in the position of the upper ridge
over the southwest the next 24 hours, so tomorrow's weather will be
similar to today. It will be another warm day in the coastal, valley
and mountain zones, the deserts will be hot and humid, and the
marine layer cloud cover will be sparse near the coast. There may be
some increase in high clouds as easterly flow aloft advects
additional mid-level moisture into the region, and the added
moisture should fuel more afternoon cumulus over the mountains.

The synoptic pattern doesn't change much next week. The blocking
ridge over the southwest will prevent deep layer tropical moisture
from moving into socal through Wednesday. Nevertheless, there will
be enough midlevel moisture in the easterly 500-700 mb flow for
scattered mid and high clouds through Wednesday. Precipitation
chances are low the next several days with the subtropical high
suppressing deep layer moisture and instability to our south.

Temperatures will be a little above average in most areas. Greatest
warming may be west of the mountains where weak subsidence and
easterly downslope flow may add a few degrees of warming.

Tropical storm ivo is forecast to weaken to a tropical depression
tonight and then to a remnant low on Sunday before dissipating.

Later in the week some deep layer moisture may work its way into
socal for somewhat greater chances at convection. Temperatures will
remain slightly above average.

Aviation
240330z... Coast valleys... Areas of low clouds with bases 900-1200 ft
msl and spread up to 15 mi inland overnight. Local vis 4-6 sm
possible on higher coastal terrain. Stratus clearing 14-16z.

Otherwise increasing clouds at above 10000 ft msl on Sunday.

Mountains deserts... Low clouds with bases 2000-5000 ft msl may
develop over portions of the low desert 12-17z Sunday, though
confidence is low. Cumulus developing over the mountain crests
during the afternoon, dissipating in the evening. Otherwise
increasing clouds at above 10000 ft msl on Sunday.

Marine
No hazardous marine weather is expected through Thursday.

Beaches
South-southeast swells from 165-175 degrees with a 12-13 sec period,
generated by tropical storm ivo, will generate elevated surf through
Monday morning. Isolated surf up to 6 ft is possible on the south
facing breaks in orange county. Main impacts on west facing beaches
will be longshore currents. A beach hazards statement is in effect
for orange and san diego county beaches tonight through Monday
morning.

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

Sgx watches warnings advisories
