Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... A large northwest swell has arrived with seas in excess of 15 feet along with larger near shore breaking waves. Low pressure will move inland into the great basin and the central valley on Wednesday. This will result in increasing northwest winds with gale force gusts expected over the northern and outer waters. Gale force winds and large northwest swell will create hazardous conditions through midweek. Moderate wind and seas will persist through the end of the week, particularly in the northern outer waters.

area forecast discussion
national weather service sacramento ca
404 am pdt Wed may 22 2019

Synopsis
Light sierra showers next couple of days as an upper low remains
over the great basin. Isolated sierra thunderstorms as well.

Mainly dry elsewhere next couple of days with near normal
temperatures. Showers and isolated thunderstorms Friday through
early next week as another low drops out of western canada.

Discussion
Isolated light showers continue over the southern half of the cwa
this morning as an upper trough digs southward through central
california. The southern cascades, northern sierra and parts of
the san joaquin valley will remain under cyclonic flow today so
isolated showers will continue these areas with enough instability
indicated to warrant an afternoon thunderstorm threat as well. A
cool airmass combined with mixed Sun and clouds today should bring
up highs at the lower elevations to a little below normal for
this time of year. Upper troughing over the great basin will
continue the shower and thunderstorm threat over the sierra
cascade range and foothills on Thursday. The airmass warms
slightly so should see a little warm up to near normal for this
time of year.

Another upper low dropping southward out of western canada
Thursday night will nudge the great basin low eastward bringing a
temporary dry period all areas Thursday night and Friday morning.

This break will be short lived however with shortwave troughs
forecast to pivot out of the pacific northwest low through norcal
bringing a threat of showers or thunderstorms by most areas by
Friday afternoon. Daytime highs slip a bit on Friday then much
more on Saturday as the upper low continues southward into norcal.

This low will bring showers and isolated thunderstorms to nearly
all of norcal with daytime highs expected to drop to 10 or more
degrees below normal.

.Extended discussion (Sunday through Wednesday)
models continue to differ with progression of upper low progged to
dig south near the ca coast and eventually track inland across
socal in the Sunday to Monday timeframe. Gfs GEFS spaghetti plots
showing good consistently among ensembles and thus the preferred
model. As a result, unsettled weather expected to continue Sunday
into Monday with best chances for showers expected over the
foothills and mountains. Model CAPE values look high enough to
support a slight chance of thunderstorms Sunday. Channeled
vorticity along the sierra nevada Tuesday will maintain a slight
chance of showers over higher elevations that persists into
Wednesday. Below normal temperatures progged into Monday with high
temps returning to near normal Tuesday, and above normal
Wednesday.

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.
