106 pm pdt Fri jul 21 2017

Synopsis
A high pressure ridge will bring seasonally hot weather inland
through the weekend, while onshore flow and the marine layer keeps
coastal areas moderate with areas of nocturnal marine clouds and
fog. A surge of monsoonal moisture early next week will bring more
clouds and cooler, but more humid days, along with a chance of
showers and thunderstorms at times. Best chance for significant
rainfall will be in the mountains and deserts. Dry and warmer again
for the latter half of next week.

Discussion For extreme southwestern california including orange...

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

the marine stratus pulled away from the coast by late morning
leaving clear skies over all of SW ca. At noon pdt, winds were
light, and temps were at or a bit below values observed yesterday at
noon.

A broad summer-time ridge covered the southern half of the country
this Friday, with a weak mid-level trough along the west coast
helping to nudge the monsoonal moisture east. This will hold most of
the shwr TSTM activity off to the east through Saturday. For Sunday
through Tuesday, a weak easterly wave heading west across NW mexico
will turn NW and then n, guided by the weak trough near the coast,
and the vast high pressure ridge to the east. This will drag a surge
of monsoonal moisture across socal with it, accompanied by mid-high
level clouds and a large pw increase.

The additional cloudiness and low-level dewpoint increase across the
lower deserts will certainly keep MAX temps lower early next week.

But it is less certain how much of this moisture will result in
shwr TSTM activity (discussed below). The moisture diminishes wed,
with shwr TSTM chances winding down over the mts deserts. Farther to
the west, the weak trough, just off the coast once again guides a
drier mid-level flow across the region for the remainder of next
week.

In terms of convection... A slight chance of thunderstorms has been
added to the forecast on Sunday over the mts as mid-level moisture
begins to increase under strong daytime heating. Any storms will
likely be isolated, but could produce dry lightning strikes, gusty
winds and brief, localized heavy rain showers. Moisture will surge
aloft on Monday ahead of the weak easterly wave. This could
destabilize the atmosphere enough for areas of elevated convection
just about anywhere. This could produce sprinkles or rain showers
and isolated lightning strikes. Due to the increased cloud cover
expected, deep thermally driven convection is less likely on mon. By
Tuesday, the upper-levels dry, and mid-level winds weaken slightly
and turn sw. With more sun, thermally driven convection on the mts
is again possible, with a drift off into the deserts, so pops are
greater again over eastern portions of the cwa.

Considerable uncertainty remains regarding timing of shwrs tstms and
amounts of rainfall, so measurable precip chances are low for any
given period Sun through tue, with the best chance in the mountains
afternoons evenings.

Aviation
211955z... Coast valleys... Through 22 0000 utc, p6sm vis and mostly
skc. 22 0000-1400 utc, stratus re-developing and moving 15-20 sm
inland, with bases around 1000-1500 ft msl, tops around 1600-2000 ft
msl, and local vis 3-5 sm. Forecast marine layer inversion strength
at 22 1200 utc of 7-8 deg c. Elsewhere, p6sm vis and mostly skc
continuing. Clearing of stratus expected during the 22 1500-1800 utc
time-frame.

Mountains deserts... P6sm vis and mostly skc will prevail through
Saturday morning.

Marine
There is a slight chance for thunderstorm activity over the coastal
waters Sunday night and Monday as an upper level disturbance moves
through the region. Otherwise, no hazardous marine weather is
expected through Wednesday.

Beaches
Highest tides will reach near or above 7 feet during the mid-to-late
evening hours each day today through Sunday. This could result in
minor tidal overflow at low-lying beach areas during times of
highest tide. A beach hazards statement GOES into effect later
today.

Also, an upper level disturbance moving through the region may bring
some thunderstorms to the coast Sunday night and Monday, potentially
resulting in a lightning threat for beach goers.

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

Sgx watches warnings advisories

evening for orange county coastal areas-san diego county
coastal areas.
