Area Forecast Discussion
National Weather Service San Francisco Bay Area
945 PM PDT Mon Aug 14 2017

.SYNOPSIS...A gradual warming trend is forecast from Tuesday
through the end of the week as a ridge of high pressure over the
eastern Pacific builds over California.

&&

.DISCUSSION...As of 9:00 PM PDT Monday...An upper level trough
brought cooler air into the district today. This can be seen at
925 mb where the temperatures dropped by as much as 5 degrees C
from yesterday. As a result highs today were about 5-10 degrees
below normal. The onshore flow increased and became more east-west
oriented keeping stratus in over much of the SFO Bay Area all
day. By 8 PM the stratus had already spread into Livermore.
Stratus will become widespread again tonight as the marine layer
will remain deep. Patchy drizzle is again expected mainly from the
San Mateo coast south.

Temperatures will be recovering on Tuesday as the trough moves
inland. Low clouds should clear to the coast in the afternoon
and temperatures will be slightly warmer. More warming is
expected Wednesday and Thursday as an upper ridge builds over the
eastern Pacific. The marine layer will compress and temperatures
will reach the lower 90s in the warmest inland locations with mid
to upper 90s in southern Monterey/San Benito counties.

The warmest days are expected to occur on Thursday and Friday. The
upper ridge breaks down over the weekend and a weak upper low
develops off the central and southern California coast.
Temperatures will be cooler but southwest flow aloft will lessen
the amount of cooling. As for cloudcover the long range models
indicate low clouds will continue at the coast and locally inland
through the weekend into early next week. Long range models are
indicating some increased moisture above 400 mb Sunday and Monday
so there could be some high clouds.

&&

.AVIATION...As of 9:45 PM PDT Monday...MVFR cigs are increasing
in coverage with a deep marine layer, patchy drizzle is forecast
tonight as well. Ongoing 925 mb level cooling, primarily focused
over the southern half of the forecast area, will tend to lower
cigs to IFR especially in spots where NW wind flow meets coastal
terrain producing drizzle or even possibly very light rain at
times. 925 mb cooling is very similar to a winter-time cold front
scenario. Light qpf is predicted by the NAM by Tue morning over
parts of the Bay Area including the San Mateo Coast as well as
from KMRY to KSNS; drizzle is indicated in KOAK, KSFO, KMRY and
KSNS tafs.

Vicinity of KSFO...Stratus with a deep marine layer, onshore winds
will usher in more stratus, possibly drizzle at times overnight.
Clearing could be slow going Tuesday, VFR forecast to return by
21z.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...MVFR cigs tending to lower to IFR with
patchy drizzle or very light rain tonight in a very deep marine
layer. Clearing will likely be slow going Tuesday.

&&

.MARINE...as of 9:27 PM PDT Monday...Northwesterly winds will
continue over the coastal waters as high pressure remains
situated over the eastern Pacific and a thermal trough resides
over California. Wind-driven short period swell will continue
through much of the forecast period.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .Tngt...SCA...Pt Arena to Pigeon Pt 10-60 nm
             SCA...Pt Arena to Pt Reyes 0-10 nm until 3 AM
