Synopsis Strong high pressure will remain in place through much
of the week and result in dry weather conditions along with above
average daytime temperatures. Clear skies and weak offshore flow
will allow for cool overnights which will warm slightly late in the
forecast period as onshore winds return.

Discussion As of 01:49 pm pst Monday... A strong ridge of high
pressure continues to dominate the weather pattern across the
entire west coast and will do so through much of the forecast
period. This has resulted in continued dry weather conditions and
above average temperatures. Meanwhile, upper level flow will
continue to advect smoke from wildfires over southern california
today and potentially into tomorrow as well. While some smoke will
be noticeable to the generally public, the heaviest concentration
of smoke will remain above the surface in the higher levels of
the atmosphere. Look for afternoon temperatures to warm into the
60s for the san francisco bay area and points northward while the
south bay down through the central coast will experience
widespread 70s.

A storm system is then forecast to approach the pacific northwest
late in the week and will help to weaken the ridge slightly. This
will allow for daytime temperatures to cool by a few degrees late in
the week and into the upcoming weekend with a slight increase in
overnight temperatures as onshore flow returns. Precipitation with
this system will stay well to the north however with ongoing dry
conditions for california.

Longer range guidance suggest a potential change in the weather
pattern sometime next week that might bring light precipitation to
portions of the state. However, confidence is low at this time
and will need to be monitored in the coming days. Until then, look
for ongoing dry weather conditions and above average daytime
temperatures to persist.

Aviation As of 9:39 am pst Monday... For 18z tafs. Upper level
winds continue to bring smoke from the southern california fires
northward across the forecast area resulting in a broken to
scattered cloud deck around 20k to 25k feet. This smoke layer will
persist through much of the day then hopefully clear out
overnight. OtherwiseVFR conditions and light winds will prevail.

Patchy fog and low clouds will return tonight over ksts.

High confidence.

Vicinity of ksfo...VFR. Light offshore winds expected through the
forecast period.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR. Generally light offshore winds.

Marine As of 2:10 pm pst Monday... Light to moderate winds will
continue along the central coast as high pressure remains over
the region. Winds will gradually increase out of the north
midweek. A longer period swell arrived today and will impact the
coast thru midweek.

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.
