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...

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
242015z... Coast valleys... Mostly clear skies through late afternoon
expected, though patchy CIGS lingering at the southern san diego
county beaches this afternoon. Lo mod confidence for timing of low
clouds tonight. High pressure suppressing marine layer, leading to
lower CIGS 800-1000 ft msl and later onset than last night. Onset
slated at coastal TAF sites after 10z but before 13z tonight with
areas of 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 between 12z-18z Sunday. Otherwise, mostly clear conditions
prevailing through the weekend.

Marine
No hazardous marine weather is expected through Wednesday.

Beaches
South-southeast swells from 165-175 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 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.
