area forecast discussion
national weather service san diego ca
910 pm pdt Fri aug 23 2019

Synopsis
High pressure is building over the state, and will thin the marine
layer and limit nocturnal low cloud development. It will also boost
daytime temperatures. Expect very warm to hot conditions inland,
with some warming over coastal areas as well, especially prior to
sea breeze onset. Some moisture will move in from the east, but no
showers or thunderstorms are expected.

Discussion For extreme southwestern california including orange...

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

at 9 pm pdt... Satellite imagery showed patchy high clouds drifting
to the SW over socal, with all the low marine clouds well offshore.

Monsoonal thunderstorms were occurring over SE az and sonora mx. The
00z miramar sounding still indicated a fairly deep marine layer near
2k ft, topped by a 5c inversion. Winds through the mid-levels were
se 10-15 kt. Weak to moderate sfc pressure gradients continued from
the coast to the deserts with peak w-sw wind gusts of 20-30 mph.

It looks like there is at least a potential to exceed forecast max
temps on Saturday over inland coastal and western valley areas,
depending on the onset of the sea breeze. Not enough confidence to
make forecast changes this evening though.

From previous discussion...

our coastal eddy keeps on cranking, but low clouds cleared out
fully and nicely this morning. The eddy will gradually fade
tonight. Low clouds will move ashore and inland overnight, but
probably not as far as they got this morning. A gulf surge is
probable in the lower desert again Saturday morning, a sort of
desert style marine layer. They should get some low clouds out
there, but not full overcast. A trough of low pressure moving
through the interior west today will quickly lift out and allow a
nose of high pressure from the pacific to build into california.

That will take care of the eddy. This banana-shaped ridge extends
from san francisco to phoenix on Sunday and Monday. That will tamp
down our marine layer so that clouds only cover the coastal areas
nights and mornings. It will also bring us a modest warming trend
through about Tuesday. The ridge weakens slightly to back off
temps a couple degrees around the middle of next week. Some
increase in monsoon moisture at mid levels of the atmosphere is
happening this weekend, but with little if any instability. That
means we'll see some cumulus clouds over the mountains during the
afternoons, and nothing more. That moisture retreats for a few
days, then models depict a return later next week. Maybe the
following weekend we get a chance of thunderstorms. Or not.

That's what we've been saying for the last couple weeks when we
were thinking we might get thunderstorms today. Needless to say,
confidence is really low. The monsoon season is quietly slipping
by without too many thunderstorm days; our next tstorm might not
arrive until september. What impact will ivo have on socal? None
in the weather department, but we do expect him to bump up in the
swell and surf (see beaches discussion below). The high pressure
could build a little stronger over socal toward next weekend,
which would bring us another modest warming trend.

Aviation
240400z... Coast valleys... Stratus will be much less widespread
tonight, with areas of bkn-ovc CIGS developing within 10 miles of
the coast 06z-10z sat. Bases will be 1200-1500 ft msl with tops to
1700 ft msl. Most vis will remain 5+ miles. Most areas will clear
15z-17z sat, withVFR conditions prevailing after 17z sat, likely
continuing Sat evening.

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

Marine
No hazardous marine conditions are expected through Wednesday.

Beaches
South-southeast swells from 160-170 degrees with a 12-14 sec period
generated by tropical storm ivo will reach the beaches of southern
california late Saturday, peaking Sunday before lowering Monday and
Tuesday. These swells could produce isolated surf up to 6 ft and
strong rip currents on the more southerly-facing beaches of orange
county. West facing beaches, mainly in 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 strong rip currents and 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.

Pz... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
