145 pm pdt Sun aug 25 2019

Synopsis
Unusually strong high pressure over the western states is expected
to continue to slowly strengthen over the next week. This should
keep afternoon high temperatures above normal for most areas, but
closer to normal along the immediate coastline and in the deserts.

Some night and morning low clouds and fog can be expected near the
coast, with mainly just afternoon clouds over the mountains and
deserts. Only a slight chance of showers and thunderstorms in the
san diego county mountains this afternoon and evening but no showers
or thunderstorms are forecast after today for our area.

Discussion For extreme southwestern california including orange...

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

midday temperatures threw a wrench in the works, with the southern
coastal areas and locally inland rising rapidly late morning under a
lower marine inversion, less clouds, some weak easterly flow that
may be ivo related, and likely some ivo related subsidence as well.

Met MOS guidance and mav MOS guidance both had 18z san diego
international airport (ksan) temps in the upper 70s, and it was
actually a bit warmer at 82 degrees. The brown field (sdm) mav met
temperature guidance had 83 83 for 18z, which actually ended up
being 89. In contrast, riverside and chino were below yesterdays
readings at 19z. Through Monday, unusual occurrences like that will
be possible until the influence from ivo GOES away.

Stronger than normal and building high pressure aloft continues to
threaten the southwest. This should keep afternoon high temperatures
above average into at least next weekend, except possibly in the
immediate coastal regions and possibly the coachella valley, with of
course the wild card being whatever ivo does to our subsidence and
flow pattern.

Some night and morning low clouds are still expected at times near
the coastline. Coachella valley high temperatures should be
moderated, at least for a few days, by a surge of cooler, low level
moist air surging in from the gulf of california.

Generally ensemble data and local WRF shows very little day to day
change in the upper level pattern and in the mid-upper level
moisture for a week or more into the future starting Monday,
including limited if any convection
some remnant mid level moisture from decaying tropical storm ivo
will be around for the next couple of days but only interesting
looking mid and high clouds for the rest of the area for most areas,
and maybe some unusual temperature fluctuations.

Temperatures could peak in the lower deserts and the coachella
valley around 109-113 degrees midweek or so, dependent on whether
the low level moisture hangs around there or not.

The upper high will be centered near socal late in the week,
although this does not seem to be intense enough for heat products
at this time, especially with some remnant moisture likely to linger
over the area, but the position of the high raises concerns for both
valleys and desert areas on the hottest days.

Aviation
252010z... Coast valleys... Mostly clear skies will prevail for the
early afternoon hours. Clouds AOA 10k ft msl still on track to
increase late afternoon into this evening as tropical depression ivo
moves northward. Stratus may impact coastal TAF sites with cigs
between 700-1000 ft msl and 4-6 sm vis. Confidence increasing for
low clouds to briefly make an appearance between 12z-16z Monday. Sct
high clouds AOA 10k ft msl prevailing through Monday morning into
early afternoon.

Mountains deserts... Sct-bkn cumulus with bases 3-5k ft msl will
continue over portions of the mountains through 04z. Low confidence
of slight chance for tstms over the mountain crests during the
afternoon, dissipating in the evening. Otherwise increasing clouds
aoa 10k ft msl tonight into tomorrow morning.

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.
