855 pm pdt Thu aug 22 2019

Synopsis
A weak trough will bring cooling through Friday as the marine layer
deepens, spreading low clouds and patchy fog into the valleys. High
pressure builds back in this weekend, flattening the marine layer
and bringing warmer days. Some monsoonal moisture will make its way
back into socal this weekend, bringing an increase in humidity, high
clouds, and some afternoon cumulus clouds over the mountains.

Discussion For extreme southwestern california including orange...

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

at 8 pm pdt... Satellite imagery showed stratus over the ca bight and
invading an area of NW san diego county. The 00z miramar sounding
had an 11c inversion based near 1900 ft msl with a deep southerly
flow around 10 kt from the sfc to around 7k ft. The sfc pressure
gradients from ksan to the deserts were moderately onshore,
supporting westerly wind gusts 25-35 mph with a peak gust of 44 mph
near whitewater.

A vigorous eddy circulation off the coast will keep gusty southerly
winds along the coast and help to drive marine clouds farther inland
tonight, perhaps reaching the inland empire by morning. The deeper
marine layer will bring more cooling inland on Friday as well. No
forecast updates this evening.

From previous discussion...

for this weekend, high pressure builds into california, warming
inland areas to slightly above average. The marine layer will be
a little shallower this weekend and spread less far inland. Only
minor variations in temperatures expected through the middle part
of next week. Monday and Tuesday look like the warmest days in the
coming week.

Monsoonal moisture will make a return this weekend and into next
week bringing an increase in humidity for the inland areas. There
will be high clouds and some afternoon cumulus clouds near the
mountains. It doesn't appear the the moisture increase will be
sufficient enough for afternoon thunderstorms, so chances of
thunderstorms have been kept out of the forecast.

Aviation
230345z... Coast valleys... Bkn-ovc stratus will spread through most
coastal areas by 05z and many of the valleys by 10z fri. Bases will
mostly be 1000-1500 ft msl with tops to 2000 ft msl overnight with a
slight increase in height after 12z fri. Higher terrain will be
obscured in clouds, though most vis will be 5+ miles below the
clouds. Clearing will be slow Friday, 15z-18z in the valleys and 18z-
21z near the coast with local bkn conditions possible after 21z fri.

Stratus will develop again Friday evening but likely with lower
bases than tonight.

Mountains deserts... Mostly clear with unrestricted visibility
through Friday evening.

Marine
No hazardous marine conditions are expected through Tuesday.

Beaches
South-southeast swells from 160-170 degrees with a 12-13 sec period
generated by tropical storm ivo will reach the beaches of southern
california late Sunday through Tuesday. These swells could produce
elevated surf locally up to 6 ft and strong rip currents on the more
southerly-facing beaches of orange county, though west facing
beaches, mainly san diego county, will have little or no effects. A
beach hazards statement is in effect for orange and san diego county
beaches Saturday night through Tuesday morning with biggest impacts
being elevated rip currents, including longshore currents.

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

Sgx watches warnings advisories
Ca... Beach hazards statement from late Saturday night through Tuesday
morning for orange county coastal areas-san diego county
coastal areas.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
