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 8:15 am pdt Sunday... Widspread clouds this
morning thanks to a deep marine layer and a weak onshore flow at
the surface. Clouds should burn-off toward the coast by late in
the morning. High temperature range will be much less than a
typical august day. Inland most spots will just be in the mid 70s
to the upper 80s while at the coast many areas will be in the 60s
and 70s.

Current forecast appears on track. No major updates planned
although may do a minor update in a bit with information on clouds
for tomorrow morning during the eclipse.

Previous discussion 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.

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.
