Synopsis Cooling will continue early this week as an upper
trough of low pressure becomes nearly stationary over the eastern
pacific. Coastal areas will see little in the way of change with
continued night and morning low clouds and patchy fog.

Discussion As of 3:00 am pdt Sunday... A nearly stationary
upper level closed low will remain along the central coast through
early to mid week. Cooler temperatures will continue this week
with comfortable day time highs expected most places with only far
inland locations experiencing warm to hot temperatures. Wildfire
smoke from the pacific northwest began to mix into the air over
the bay area and central coast yesterday. Widespread low clouds
and fog over the coastal waters will be ushered inland this
morning on onshore breezes with returning low clouds and fog again
tonight and Monday morning. Cloud coverage mid-late Monday
morning will be challenging to predict much of it depending upon
the depth and strength of the marine layer, though of course, the
farther inland one is the better chances there are for clear skies
during the solar eclipse. Patchy high clouds are possible over
the area Monday as well. Medium range forecasts indicate some
strengthening of an upper level high over the desert southwest
and california.

Aviation As of 04:30 am pdt Sunday... For 12z tafs. MVFR to ifr
conditions at most airports as stratus continues to spread inland.

Expecting stratus to burn off late this morning. Westerly winds
this afternoon at around 15 kt.

Vicinity of ksfo... MVFR CIGS currently around the airport
expected to burn off late this morning around 18-19z.VFR
conditions this afternoon with westerly winds around 15 kt.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals... Ifr CIGS at kmry and ksns. Expecting MVFR
toVFR conditions around 18-19z. Low CIGS should return again this
evening.

Marine As of 02:20 am pdt Sunday... Moderate northwesterly
winds will continue over the northern outer waters through tonight
as high pressure continues to build over the eastern pacific.

Accompanying breezy winds will be locally steep wind waves before
winds begin to decrease tonight.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
