Generally light to locally moderate south to southwesterly winds will prevail across the coastal waters with the exception of strengthening northerly winds over the northernmost outer waters. Strong northerly gale force winds are forecast to be confined mainly to the northernmost outer waters north of point reyes from this evening through at least Thursday evening.

Synopsis Cooler temperatures are expected today and Thursday
before trending warmer Friday and Saturday. There is the potential
for moderately gusty offshore winds over the north and east bay
hills Thursday and Friday nights.

Discussion As of 9:05 am pdt Wednesday... The marine layer is
about 1500 feet deep and current satellite imagery shows coastal
low clouds extending well inland this morning. Stratus should be
fairly slow to clear from near-coastal areas as the area remains
under a moderate onshore flow, with 2.1 mb from sfo to sac. High
temperatures today are forecast to be a few degrees cooler than
yesterday in most places, with 60s to lower 70s at the coast, and
80s to lower 90s inland. Some of the warmest inland areas could
see highs in the middle 90s.

The upper level ridge off the california coast will continue to
weaken as an upper level low drops south from western canada into
the pacific northwest. This will lead to continued cooling during
the next couple of days. Thursday will be the coolest day as an
upper level disturbance moves south across nevada with the trough
axis moving through our district. This disturbance will tighten
an offshore surface pressure gradient with north to northeast
winds increasing Thursday night as this trough moves through. The
12z run of the nam12 model shows 925 mb winds in the 25 to 35 kt
range... Strongest winds over the higher terrain in napa county.

After weakening on Friday the north to northeast winds will ramp
up once again Friday night as the flow aloft becomes northeast on
the back side of the trough bringing another night of potentially
gusty winds for the north and east bay hills Friday night.

Currently there are no watches or advisories for the north and
east bay hills but will continue to monitor.

Longer range models indicate a long-wave upper trough over the
eastern pacific, with high pressure over the rocky mountain
states. This will maintain cool or near seasonally normal temps
going into the first week of summer.

Aviation As of 4:44 am pdt Wednesday... For 12z tafs.

Widespread stratus infiltrated well inland overnight under a very
deep marine layer. Low clouds will linger through the morning with
a relatively late burn off around 18z-19z today. CIGS will return
around 03z-04z this evening. Light and locally variable winds
will continue through the morning then strengthen becoming
westerly around 10-15 kt in the afternoon.

Vicinity of ksfo... Borderline MVFR to ifr CIGS will continue
till around 18z-19z. Confidence is low on timing, CIGS may end up
clearing slightly earlier than forecast. Light winds will turn
onshore this afternoon and strengthen to around 15 kt.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals... Ifr to lifr conditions will continue
till around 18z. Light to locally variable winds will turn
onshore this afternoon and strengthen to around 8-12 kt.

Marine As of 8:37 am pdt Wednesday... Generally light to
locally moderate south to southwesterly winds will prevail across
the coastal waters with the exception of strengthening northerly
winds over the northernmost outer waters. Strong northerly gale
force winds are forecast to be confined mainly to the northernmost
outer waters north of point reyes from this evening through at
least Thursday evening. Gusty northerly winds will become more
widespread across the coastal waters Thursday evening through
Friday. This will result in steep fresh swell creating hazardous
seas conditions, particularly for smaller vessels.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
