Area Forecast Discussion
National Weather Service San Francisco Bay Area
919 PM PST Wed Nov 29 2017

.SYNOPSIS...High pressure will bring dry and mild weather through
the end of the work week. A weak trough will pass north of the Bay
Area on Saturday keeping the best rain chances closer to the
Oregon border. Longer range trends suggest dry and cooler
temperatures Sunday and Monday followed by above normal
temperatures by the middle of next week.

&&

.DISCUSSION...As of 9:15 PM PST Wednesday...Surface high pressure
over the Great Basin brought offshore flow to the area today
making for a pleasant fall day. Highs were pretty uniform across
the area with mid to upper 60s in the lowlands and mid to upper
50s in the hills...generally a few degrees warmer than yesterday.

Little change is expected the next few days as westerly flow
dominates the upper levels. Patchy fog is possible again in the
wind protected valleys tonight. Daytime maximum temps will be in
the 60s to near 70 with overnight minimum temperatures in the mid
30s to upper 40s.

Clouds increase Saturday as an upper level low approaches the
Pacific Northwest. This upper low will dig southeast into the
Great Basin. Models continue to trend drier with latest models
showing only a slight chance of rain for the North Bay. It will
turn colder Sunday into the beginning of next week as an upper
level ridge builds sharply off the west coast bring a northerly
flow aloft. It appears the arctic air will stay east of the
district so it will not get super cold here but there could be
near freezing low temperatures in the coldest inland locations.

Medium range models bring the upper ridge over the west coast the
middle of next week which would result in much warmer
temperatures. No rain is in the foreseeable future through the
second week of December.

&&

.AVIATION...As of 4:00 PM PST Wednesday for 00Z TAFs...Mainly
clear skies will prevail through tonight with a few scattered
high clouds passing through this afternoon/evening. Patchy fog
possible over the North Bay overnight. Wind will remain light
through much of the forecast period.

Vicinity of KSFO...VFR conditions will prevail through the
forecast period. Light onshore flow under 10 kt expected through
tonight.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR with generally light winds through
the period.

&&

.MARINE...as of 03:59 PM PST Wednesday...Moderate northerly winds
will continue this afternoon across the  waters. A long period
northwest swell will remain in place into  this evening resulting
in hazardous conditions before swell  heights and periods decrease
somewhat tonight. Winds will briefly  decrease tomorrow morning
before picking up once again in the afternoon and evening.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...

             SCA...Pt Pinos to Pt Piedras Blancas 0-10 nm until 9 PM
