area forecast discussion
national weather service san diego ca
930 am pdt Sun aug 20 2017

Morning update
Coastal stratus is slowly eroding from the east this morning and
will push to the coast by around 18z. The forecast remains on track
with an upper low just off the coast becoming a little stronger
tonight. This may bring some drizzle to the coastal late tonight and
Monday morning. No changes were made to the forecast this morning,
and the previous forecast discussion is listed below for more
details.

Synopsis
A weak low pressure system off the southern california coast will
keep high temperatures a few degrees below average through Monday
with areas of night and morning coastal low clouds and patchy fog
extending into portions of the inland valleys. Mid level monsoonal
moisture to the east and north will bring some afternoon clouds
to the mountains with a slight chance for thunderstorms for the
san bernardino county mountains and adjacent deserts for Monday
afternoon. There will be warming to near average high temperatures
for Tuesday through Thursday... Then a few degrees above average
for next weekend.

Discussion For extreme southwestern california including orange...

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

a weak low pressure system will remain off the southern california
coast through Tuesday... Then weaken and move inland on Wednesday
and Thursday with a trough of low pressure moving inland through
the pacific northwest and northern rockies for Thursday into
Friday.

While the atmosphere aloft over the southern california coastal
waters into adjacent coastal areas will remain quite dry... The
cyclonic circulation around the low pressure system will draw
some mid level moisture northward and northwestward across the
eastern deserts of southern california. The models have trended
slightly farther to the north and east with more significant
moisture that will be drawn northward tonight into Monday morning.

This lessens the chances for any nocturnal convection tonight to
extend into southwestern california. Some clouds are expected
near the mountains into the adjacent deserts of san bernardino
county for this afternoon... With a slight chance of thunderstorms
for the san bernardino county mountains and adjacent deserts for
Monday afternoon.

High temperatures will remain a few to around 5 degrees below
average for today and Monday. Areas of night and morning coastal
low clouds and patchy fog will extend into portions of the inland
valleys.

For Tuesday through Thursday... High temperatures will return to
near average with areas of night and morning coastal low clouds
and patchy fog extending into the western valleys.

For next weekend... High pressure will begin to develop over
arizona. This will bring warming with high temperatures warming to
around 5 degrees above average with night and morning coastal low
clouds and patchy fog not extending much farther inland than the
far western valleys. Some mid level moisture in southeast flow
aloft may return some afternoon clouds to the mountains.

2100 ft msl, tops 2000-2800 ft msl and areas of vis 3-5 sm in the
inland valleys, will likely gradually clear to the coast through
2100 utc, while p6sm vis and skc continues elsewhere. Marine layer
inversion strength of around 8 deg c this morning. 2100-21 0000 utc,
mostly skc and p6sm vis, except within 3 sm of the coast where bkn

Beaches

overflow of low-lying coastal areas. A beach hazards statement
remains in effect through this evening.
