Area forecast discussion 
National Weather Service San Francisco Bay area
104 PM PDT Wednesday Aug 27 2014

Synopsis...high pressure along the West Coast will maintain dry
weather conditions and keep temperatures near seasonal averages
through the remainder of the week. A weak trough will then impact
the region by late in the weekend...only to cool temperatures
slightly.

&&

Discussion...as of 1:00 PM PDT Wednesday...upper level ridge of
high pressure will continue to dominate the West Coast through
late week. As a result...a slight warming trend can be expected
over inland areas through at least Friday. Near the coast...very
little change is expected from day to day with respect to
temperatures. However...a modest marine layer is forecast to
return and should bring about more widespread overnight/early
morning low clouds across coastal locations over the next few
days.

By late Friday into Saturday...the forecast models are in good
agreement with pushing the next middle/upper level trough into the
Pacific northwest. This feature will drop southward across our
region through the weekend and cool temperatures down by a few
degrees. In addition...limited moisture from the remnants of
Hurricane Marie is forecast to be advected across the northern
California Friday and Saturday. While precipitation chances remain
very low...can expect at least an increase in middle/high level
clouds through the weekend. Otherwise...seasonal temperatures and
dry weather conditions will continue into the first part of next
week.

Aviation...as of 11:00 am PDT Wednesday...outside of a patch of
clouds over coastal Sonoma VFR for the rest of the day (including
at the terminals). Decided to bring back MVFR late tonight for
most spots based off the WRF which initialized well. Winds should
be fairly light (generally under 12 kt) be a non-issue today. High
confidence through 00z.

Vicinity of ksfo...VFR today. Onshore winds to around 15 knots. MVFR
ceilings possible late so added a tempo for 11z to 15z. High confidence
through 06z.

Ksfo bridge approach...similar to ksfo.

Monterey Bay area terminals...VFR through this afternoon. MVFR
with stratus likely late evening after 06z. High confidence
through 02z.

&&

Marine...as of 1:00 PM PDT Wednesday...southerly swell from
Hurricane Marie will gradually subside through the end of the
week. Mostly light northwest winds will continue over the coastal
waters through Thursday. Winds increase Friday into the weekend.
Southwest swell moves into the waters over the weekend with lower
heights.
