Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... High pressure off the california coast will continue to strengthen through the day resulting in increasing northwest winds, which will prevail through much of the upcoming weekend. Sustained gale force winds are expected along the big sur coast, south of point pinos, this afternoon and evening. Gale force winds will also be possible for the northern outer waters, north of pigeon point, Friday evening through Saturday morning. More details will be addressed in future updates. Steep fresh swell from strong winds will create hazardous seas into the weekend, particularly for operators of small crafts.

Synopsis
Hot and dry weather this week, peaking this weekend.

Discussion
A few high clouds are moving into norcal early this morning ahead
of the approaching short-wave as the upper ridge is displaced to
the east. Current temperatures are within a few degrees of
readings from 24 hours ago and generally range from the mid 40s in
the mountain valleys to the 60s to lower 70s across the central
valley.

Highs today are expected to be similar to Tuesday's as the
incoming short-wave temporarily halts the warming trend. The
moderate delta breeze will continue and may bring a few degrees of
cooling to areas influenced by it. Deep convection later today is
expected to remain along the or ca border and northward into the
pacnw.

The warming trend will return Thursday as ridging strengthens
along the west coast. Widespread triple digits return to the
valley on Friday as surface flow becomes northerly and the delta
breeze diminishes. It appears that the heat will peak on Saturday
with much of the valley forecast to be around 105 along with
breezy north winds.

.Extended discussion (Sunday through Wednesday)
hot conditions continue on Sunday, but a cooling trend begins
that will bring near normal temperatures for the rest of the
extended period.

Sunday morning should be quite warm, remaining in the upper 60s
to mid 70s for the valley, foothills, and delta, and even into the
lower mountains. This is due to a warm airmass and breezy
northerly winds late Saturday into Sunday morning. As the ridge
axis shifts eastward later Sunday, onshore develops. This could
bring cooler temperatures to delta breeze influenced areas,
keeping temperatures there below triple digit levels. The northern
and central sacramento valley could actually see temperatures as
hot or even a little hotter than Saturday, though, with projected
highs of 106 at redding and red bluff.

Temperatures on Monday morning will be noticeable cooler across
the area. Minimums in the delta and sacramento metro area may drop
into the 50s, with other areas also seeing a 5-10 degree drop
compared to early Sunday. Afternoon highs are expected to remain
below triple digits across the area. Near to slightly above normal
temperatures continue through mid week. Ek

Aviation
Vfr conditions expected the next 24 hours. Winds generally under
10 knots are expected except near the delta, where gusts to 30 kt
are possible. Ek

Sto watches warnings advisories None.

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.
