Area Forecast Discussion
National Weather Service San Francisco Bay Area
309 AM PDT SAT AUG 27 2016

.SYNOPSIS...Very little change is expected through at least the
middle of next week. Temperatures will be near or slightly below
normal through the period. Areas of night and morning low clouds
will give way to sunny skies by midday for inland areas. Most
coastal areas will continue to see widespread low cloud cover
persist through the daytime hours.

&&

.DISCUSSION...As of 3:00 AM PDT Saturday...Broken record forecast
as we approach the final week of August. After countless days
of widespread morning clouds with mostly mild daytime
temperatures, look for little change at least through the middle
of next week. At the surface the flow continues to be moderately
onshore while the marine layer is still in excess of 2,500 feet
these two factors will produce more cooler than normal readings.

A ridge of high pressure will start to build into our region over
the next several days which will help to bring some warming
especially for inland regions. Spots will away from the coast will
increase 3 to 7 degrees with widespread upper 70s to upper 80s
forecast. Coastal areas will generally be in the 60s to lower 70s.
Hot weather will be confined to southern Monterey and San Benito
counties with 90s to lower 100s anticipated. Smoke is expected to
mostly stay confined south of the San Francisco Bay Region and Santa
Clara County.

Longer range models flip to a trough pattern for the second half
of next week and keep that in place going into the following week.
Models are in disagreement with the depth of the trough however
there is general agreement that we will see another drop in
temperatures which could last through the first week in September.
The bulk of any rain should remain to our north.

&&

.AVIATION...as of 10:48 AM PDT Friday...Low clouds quickly
dissipating over inland areas around the San Francisco Bay with
generally weak southerly winds. Cloud cover slower to burn-off
over the North Bay however. Meanwhile, low clouds persist over
much of the Monterey Bay Region as the marine layer remains around
2800 feet in depth. Thus, this area may remain under low clouds
through much of the day, potentially breaking out for a few hours
this afternoon. Onshore flow will increase slightly though
the afternoon and early evening with low clouds likely to spread
back inland late this evening and persist into Saturday morning.

Vicinity of KSFO...Low ceilings have scattered out over the
region this morning with variable to light southerly winds. Wind
speeds will then increase this afternoon out of the west/southwest
with the onset of the sea breeze. Low clouds likely to return
around 04Z this evening and will persist into Saturday morning.

High confidence.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...MVFR ceilings persist over the region
this morning and will likely remain in place through much of the
day. However, inland areas such as KSNS may scatter out briefly
this afternoon before low clouds spread back inland this evening.
Onshore winds will increase slightly through the afternoon as the
sea breeze develops.

High confidence.

&&

.MARINE...as of 10:48 AM PDT Friday...A weak surface pressure
gradient across the coastal waters will maintain generally light
winds and seas through the weekend. Locally stronger and gusty
winds anticipated north of the Bay Bridge in the afternoon hours.
A mixed short period northwest swell and a long period southerly
swell will continue to impact the coastal waters.
