134 pm pdt Sun jul 22 2018

Synopsis
Isolated thunderstorms are possible near the mountains in the
afternoons through Monday. Strong high pressure aloft will move
into southern california through mid week bringing a period of
very hot weather except near the coast and at the highest
elevations of the mountains. For areas near the coast, a shallow
marine layer and a weak coastal eddy will keep areas near the
coast not as hot with patchy night and morning low clouds and fog.

For late in the week into next weekend, the high pressure will
weaken slightly and begin to shift northward. This will bring a
slow cooling trend into next weekend with a return of monsoonal
moisture for next weekend.

Discussion For extreme southwestern california including orange...

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

at 1 pm, water vapor satellite imagery displayed an upper-level
low around 580 miles southwest of san francisco, and an upper-
level ridge centered over new mexico. Visible satellite showed
cumulus build-ups over the mountains, and patchy altocirrus across
the region. Isolated thunderstorms are possible over portions of
the mountains this afternoon, however a small cap on the miramar
12z sounding at 500 mb may prevent storms from developing until
later this afternoon. High temperatures today will be near
seasonal normals for most of southwestern california. Isolated
mountain storms are possible again Monday afternoon, with the rest
of the work week becoming dry.

The aforementioned ridge will slowly build west through the
middle of the week, with h500 heights of 599 dm centered over
southern ca and western az on Wednesday. This will create a heat
wave over the region, with Tuesday and Wednesday expected to be
the hottest days. Highs will be 10-15 degrees f above normal as
h850 temperatures peak around 33 deg c near desert areas and 30
deg c near the coast. Excessive heat warnings remain in effect
for most inland areas, and a heat advisory remains in effect for
coastal areas a few miles inland from the beach for Monday through
Thursday. A shallow marine layer and weak coastal eddy is
expected to keep locations along the immediate coast not as hot.

Night and morning low clouds will be patchy, but should develop
across coastal areas throughout the week. Some inland areas won't
get much overnight temperature recovery, with low desert areas
only getting down into the 90s, and foothill locations only
lowering into the 80s Tuesday through Thursday mornings. Please
see the excessive heat warning and heat advisory for additional
details, and the climate section below for high temp records.

The ridge will move a bit to the northeast next weekend, which
will help lower our highs back near seasonal normals, and possibly
help return monsoonal moisture to the region for afternoon evening
mountain desert storms.

Aviation
222000z... Coast valleys... Mostly clear skies with unrestricted vis
will prevail through this evening. Patchy bkn stratus will develop
and could spread 10 miles inland late tonight, but timing of CIGS at
airports is low confidence. Best chances of CIGS are 09z-15z mon
with bases 900-1300 ft msl and tops to 1500 ft msl.

Mountains deserts... Isolated tsra could occur again this afternoon,
with bases 8000-9000 ft msl and tops to 35000 ft msl. Strong
up downdrafts, llws and local surface gusts to 40 knots will be
possible with any thunderstorms. Otherwise, mostly clear skies with
unrestricted vis will prevail through Mon morning.

Marine
West-northwest winds will occur in the outer coastal waters, mainly
near san clemente island, this afternoon evening, with gusts to 25
kt. Similar winds are possible again Monday afternoon evening. A
small craft advisory has been issued for the outer waters from 2-10
pm today. Otherwise, no hazardous marine weather is expected through
Friday.

Beaches
High surf advisory will be in effect Monday through Wednesday.

Building south-southwest swell from 200 degrees late today will
bring high surf Monday through Wednesday. Models indicate swell
peaking at 4-5 feet 19 seconds Tuesday. The highest surf will be on
the southwest facing beaches of orange and northern san diego county
where waves of 6-8 ft are likely. The surf and swell will gradually
lower Thursday.
