312 pm pst Mon dec 17 2018

Synopsis
Light rain will continue across the northern portion of california
tonight and tomorrow. Another system will bring a chance of light
precipitation near the end of the week.

Discussion
Precipitation has moved out of the area with dry conditions present
across northern california this afternoon. Some mid-level clouds can
be seen on satellite overspreading the northern portion of the
sacramento valley associated with a shortwave in the pacific
northwest. This feature will also bring some light rain to the
coastal mountains, northern valley, and the northern sierra-cascades
tonight through tomorrow night. Rain amounts look to be around a
quarter of an inch.

Ridging builds back in mid-week bringing a brief period of quiet
weather. Highs on Wednesday look to be the warmest of the week
reaching into the low 60s in some locations.

A quick system will move across northern california Thursday night
into Friday. Rain amounts look to be less than an inch, with most
the area probably seeing a quarter of an inch or so. Any snow
impacts look minimal at this time as snow levels remain above 6000-
6500 feet.

.Extended discussion (Friday through Monday)
there may be some lingering precipitation on Friday as a shortwave
moves across northern california. Predominantly dry conditions will be
seen Friday night and Saturday before another wave moves across the
northwest CONUS bringing more chances for rain and mountain snow
Saturday night through early next week. The ECMWF is quicker with
the onset of precipitation with this system than the GFS at this
point, with rain beginning Saturday night and the GFS holding off
until Sunday afternoon. As far as amounts, precipitation generally
looks light with totals nearing an inch in some locations over the
course of two days. Snow totals may be a couple inches, although
there could be some travel impacts with the upcoming holiday
weekend. This far out, amounts are likely to change some so keep up
to date on the forecast.

Aviation
Influx of higher level clouds will mask the lower strato-cu deck
with bases mostly 020-035 agl over norcal. MVFR CIGS mainly over
nrn sac vly and higher terrain. Overnite stratus fog and local
ifr lifr conditions forecast from krbl-kmod after 06-08z lasting
into Tue morning. Chance of light rain returns to NRN mnts and
nrn sac vly after 12-18z tue.

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.
