area forecast discussion
national weather service san diego ca
407 am pdt Sun aug 25 2019

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

Discussion For extreme southwestern california including orange...

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

moisture fields are quite high around the area attm, especially
in the lower deserts, with dewpoints there in the 70s, and west of
the mountains they are in the 60s. Temperatures are mild across
the area, in the 60s and 70s west of the mountains, to the 80s in
the lower deserts.

Low level moisture continues to ooze into socal from the south
and southeast. In addition, the remnants of tropical storm ivo to
the southwest will spread high level moisture into socal later
today, which should keep temperatures from soaring even with a bit
warmer temps aloft and some minor subsidence.

Have added a very slight chance of thunderstorms over the
mountain peaks of san diego and riverside counties where moisture
will pool and surface heating could help to fire a few cells. The
high-resolution models continue to indicate this potential as
well. The limiting factor for more significant convection, given
ample low level moisture, would be an unfavorable wind profile and
weak updraft strength, and weak subsidence possible to the
southwest from the decaying tropical cyclone.

An expanding upper level ridge of high pressure will build into
socal Monday through Wednesday from arizona. This dome of warmer
air aloft will kick temperatures about 5 degrees above normal (and
about 4-6 degrees above recent high temperatures and today's
forecast highs) with high temps in the lower deserts and the
coachella valley likely to wind up to the 110-112 degree range
Monday through Wednesday. These temperatures could trigger low end
heat headlines but confidence is low at this time, not to mention
the heat risk data is mainly below trigger levels.

Not much change in the pattern through next weekend, although
some return moisture will be possible during the period, which
could help to lower the MAX temps, but introduce more
uncomfortable humid conditions once again. Still not looking at
enough deep tropical moisture to add chances for thunderstorms.

Aviation
251030z... Coast valleys... At 10z, areas of low clouds with bases
900- 1200 ft msl over the coastal waters. The low clouds could
move onshore and impact coastal TAF sites with low CIGS between
12z and 16z, but confidence is low. Otherwise, increasing clouds
at above 10000 ft msl today.

Mountains deserts... Low clouds with bases 2000-5000 ft msl may
develop over portions of the low desert 14-17z today, though
confidence is low. There is a slight chance for tstms over the
mountain crests during the afternoon, dissipating in the evening.

Otherwise increasing clouds at above 10000 ft msl today.

Marine
No hazardous marine weather is expected through Thursday.

Beaches
South-southeast swells from 160-170 degrees with a 12-13 second
period, generated by the now tropical depression ivo, will
generate elevated surf through Monday morning. Isolated surf up to
6 ft is possible on the south facing beaches of orange county.

Main impacts on west facing beaches will be longshore currents. A
beach hazards statement remains in effect for orange and san diego
county beaches through Monday morning.

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

Sgx watches warnings advisories
Ca... Beach hazards statement through Monday morning for orange county
coastal areas-san diego county coastal areas.

Pz... None.
