Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Surface high pressure 650 miles west of the bay area will gradually move southeast and weaken through early week. As a result winds will diminish tonight and remain mainly light Monday into Tuesday. South to southwest winds Tuesday precede the arrival of a moderate cold front Tuesday evening and early Wednesday morning. Modified arctic air and high pressure will build over the eastern pacific and extend into the intermountain west. Post cold frontal northwest winds will become gusty over the coastal waters and bays mid to late this week. A dry cold front will usher in a reinforcement of modified arctic air from the north and northeast beginning Saturday evening and continuing into early next week.

150 pm pst Sun dec 17 2017

Synopsis
Dry conditions this week except for a chance of rain or snow for
most of the region Tuesday night and Wednesday. Breezy northerly
winds Wednesday night and Thursday.

Discussion
Some high clouds passing overhead the next couple of days with a
ridge of high pressure over the area. The ridge will weaken Monday
night into Tuesday and surface flow in the valley will become
light southerly. This will help to increase the dewpoints and may
allow for some patches of fog to form... Mainly near the water
ways Tuesday morning from around the sacramento region southward.

A fast moving weather system will move through the region Tuesday
night into Wednesday and may bring 3 to 7 inches of snowfall to
the mountains with minimal QPF in the valley. Models show the
system a little further west than yesterday which has allowed it
to pick up a little bit more moisture. Colder air moving over the
region may keep daytime highs in the 50s for the valley to the 30s
for the mountains and will likely bring lower snow levels. Breezy
southeast conditions in the valley are expected for at least
several hours as the front moves through.

Dry weather returns for Wednesday night with breezy northerly
winds developing by Wednesday night.

.Extended discussion (Thursday through Sunday)
a ridge will build back in for the start of the extended period
bringing dry weather and near seasonal temperatures. The 12z ec
has come more in line with the GFS in dropping a trough south into
the region on Saturday. This could bring a few light showers to
the sierra throughout day. There is still some disagreement on
this system though and confidence in low and anything we do see
looks to remain light. The trough will also bring in much cooler
air especially in the higher elevations where highs could run
5-10 degrees below normal. Overnight lows look to fall into the
low to mid 30's in the valley and teens and 20's in the higher
elevations.

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.
