Synopsis
High pressure aloft will bring warm weather and a shallow marine
layer through next week. Subtropical moisture will move in from the
southeast bringing mid and high level clouds at times.

Discussion For extreme southwestern california including orange...

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

a surge of low level moisture into the lower deserts this morning
raised the dewpoint to a sweltering 77 at thermal and 75 at
borrego. These are some of the highest values of the summer, and
it's hard to keep cool in these warm, humid airmasses. In contrast,
coastal dewpoints this morning ranged from 60 to 65, and the actual
temperatures ranged from 65 to 70. The low level moisture surge
into lower deserts will persist into Sunday before relenting.

A broad quasi-stationary subtropical ridge of high pressure
extending from california to texas will be our main weather
maker through next week. This blocking ridge will prevent
tropical storm ivo from moving north and significantly impacting
socal. Ivo will weaken to a tropical depression tonight and then to
a remnant low on Sunday before dissipating.

Midlevel moisture in the easterly 500-700 mb flow between these
two systems will draw subtropical moisture into the southwest at
times for mid and high level 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.

Later in the week some deeper layer moisture may work its way
into socal for somewhat greater chances at convection. This will be
monitored over the coming days. Temperatures will remain slightly
above average.

Aviation
241530z... Coast valleys... Mostly clear skies through late afternoon
expected. Somewhat low confidence for the timing of low clouds
tonight. High pressure suppressing marine layer, leading to lower
cigs 700-1000 ft msl and later onset than last night. Current
thinking is onset at coastal TAF sites after 09z but before 13z
tonight with vis 4-6 sm. Scatter out Sunday morning after 15z.

Mountains deserts... Surges of moisture from the southeast may bring
periods of bkn CIGS 2000-5000 ft msl to areas of the coachella
valley this morning and Sunday morning. Otherwise, mostly clear
conditions prevailing through the weekend.

Marine
No hazardous marine weather is expected through Wednesday.

Beaches
South-southeast swells from 160-170 degrees with a 12-14 sec period,
generated by tropical storm ivo, will reach the beaches of southern
california late Saturday. Swells and surf will peak Sunday before
lowering Monday and Tuesday. These swells could produce isolated
surf up to 6 ft and strong rip currents on south-facing beaches of
orange county. West facing beaches, mainly in san diego county, will
have minor impacts. A beach hazards statement is in effect for
orange and san diego county beaches Saturday night through Tuesday
morning with biggest impacts being strong rip currents and longshore
currents.

Skywarn
Skywarn activation will not be needed this weekend.

morning for orange county coastal areas-san diego county
