Synopsis Onshore wind flow today will lead to cooler
conditions through Tuesday. Modest warming is expected during the
second half of the week, however highs will fall well short of
the recent heatwave.

Discussion As of 8:37 am pdt Monday... Completed a minor
forecast grid update to account for current sky cover which is
showing mostly clear conditions for santa cruz monterey and san
benito while a deep marine layer over the bay area allowed low
clouds to push into the far east bay valleys early this morning.

Onshore gradients are around 2 mb at this hour but winds out in
the delta are howling with travis afb currently sustained at 23 kt
from the southwest and gusting to 29 kt. This will keep a cool
onshore wind flow in place today into Tuesday as a weak shortwave
moves onshore near the oregon border. Still expect morning clouds
to slowly mix out and burn back to the coast.

Forecast for the upcoming work week looks benign and seasonable
with a zonal flow aloft in place. Expect seasonable daytime highs
through midweek then perhaps slight warming later in the week
before the next trough arrives Friday Saturday with a cooling
trend.

Prev discussion As of 3:00 am pdt Monday... Clouds mostly
cleared from our CWA later yesterday but satellite shows that they
have returned to san mateo county northward. Clouds are
continuing to stream to the southeast and will be down into
monterey county by sunrise. Patchy fog and drizzle can be expected
into the morning.

Synoptically the ridge of high pressure that had been overhead is
now well to the east while the onshore flow combined with a
moderate marine layer will lead to cooler conditions compared to
yesterday especially for spots away from the coast. Highs will
range from 60s near the water with mostly 70s to mid 80s inland.

In general, temperatures will be 3 to 6 degrees cooler compared to
Sunday. Similar conditions can be expected tonight into Tuesday.

By Wednesday a ridge of high pressure will rebuild into the
pacific and toward our region. This will lead to slight warming
into Thursday. Inland highs will return to the upper 70s to lower
90s with coastal spots in the 60s to the mid 70s. Those
temperatures will hold into early next week and possibly into the
following week.

Aviation As of 06:35 am pdt Monday... Quick update to the
morning forecast. As mentioned before the non-typical marine layer
is eroding quickly around the bay. Possible right exit of upper
jet with subsidence may be to blame. None the less. Koak is now
vfr. Will keep sfo as a mixed bkn but conf is low.

Vicinity of ksfo... MVFR CIGS around sfo this morning. Based on
timing of yesterday and model guidance today will keep the 17-18z
clearing. Conf is low to moderate.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR. CIGS return tonight.

Marine As of 08:23 am pdt Monday... Light to moderate northerly
winds will persist over the coastal waters as high pressure
remains over the eastern pacific. Locally stronger winds will be
possible along the immediate coast and in san francisco bay. A
dominant southerly swell will persist into Wednesday morning.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
