Area Forecast Discussion
National Weather Service San Francisco Bay Area
1041 PM PDT Tue Nov 1 2016

.SYNOPSIS...High pressure is building and will bring dry and
seasonably mild weather to the region for the rest of the work
week. Next pacific storm approaches the North Bay by Saturday
night or Sunday with a chance of some light rain.

&&

.DISCUSSION...as of 9:00 PM PDT Tuesday...An upper level trough
is now east of the area with decreasing cumulus clouds. As this
trough drops south it will form into a closed low over Arizona
while the storm track shifts further north. This will bring a
weak offshore flow to the district meaning drier and warmer
weather Wednesday and Thursday. Temperatures should level off
Friday as the upper low moves east on Friday and offshore flow
diminishes. The next upper trough approaches the Pacific Northwest
Saturday and Sunday. Latest medium-range models indicate a chance
of rain only down to the North Bay on Sunday. Dry weather returns
to all area early next week. The 8-14 day forecast calls for
below normal precip for much of the country except around Texas.

&&

.AVIATION...as of 10:41 PM PDT Tuesday...Clear skies prevail at
this hour. Patchy fog is possible over the North Bay overnight
with calm winds and clear skies however confidence remains low
that it will materialize with high clouds streaming in overhead.
Otherwise light winds and mainly clear skies expected across area
terminals tonight.

Vicinity of KSFO...VFR conditions will prevail through the
forecast period. Moderate onshore winds will continue to ease
becoming light overnight.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR conditions will prevail through the
forecast period. Light winds will persist through the night.

&&

.BEACHES...as of 02:54 PM PDT Tuesday...A storm system currently
over the NPac is gaining steam and will result in large swell for
the Bay Area coastline Thursday into Friday. Latest model guidance
continues to indicate forerunners arriving on Wednesday with a
period of 18-20 seconds but only a few feet in height. Swell will
build Wednesday night and Thursday with swell greater than 15 ft
with a period of 16-18 seconds. The larger swell train will peak
Thursday afternoon and gradually diminish Thursday night into
Friday. The resulting surf/breaking wave height will be greater
than 20 feet and locally over 25 feet at favored break points. In
short, persons venturing to area beaches on Wednesday and Thursday
should pay attention to the ocean...use caution and never turn
your back on the ocean.

&&

.MARINE...as of 8:49 PM PDT Tuesday...High pressure over the
eastern pacific will result in light to moderate winds over the
coastal waters. southerly winds will briefly develop tonight and
wednesday over the northern waters as a cold front approaches the
region. a building long period northwest swell will arrive later
this week. mariners are urge to use caution on thursday near
harbor entrances...sand bars and the immediate coastline for
shoaling hazards due to the longer period swells.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .Tngt...None.
