233 pm pst Tue dec 18 2018

Synopsis
Light rain north of marysville will end tonight leaving Wednesday
dry with near normal temperatures. A system will bring light rain
and mountain snow Thursday night through Friday. Unsettled weather
looks likely late weekend into early next week.

Discussion
Light precipitation continues in areas north of marysville through
this evening with additional QPF amounts less than a quarter of an
inch expected. Mid-level ridging will move in and dominate the
california coast Wednesday, with another round of fog expected in the
valley tomorrow morning. As skies clear, any fog should mix out by
the afternoon leaving dry and near normal temperatures for the rest
of the day. Models have become increasingly more consistent in a
wave moving across the region Thursday night into Friday.

Precipitation with this is expected to be light with rain totals
under an inch and possibly an inch or two of snow. Some lingering
snow may be possible over the sierra into Friday evening, with
conditions becoming dry during the overnight hours.

.Extended discussion (Saturday through Tuesday)
weak ridging Saturday will keep conditions dry Saturday afternoon
ahead of another potential system Sunday. The GFS has slightly
aligned with the ECMWF becoming more wet Sunday night into Monday,
mainly north of the marysville area. Except the forecast may shift
slightly again as run to run consistency with the system during this
time has been low.

On Monday, christmas eve, a trough will move across the pacific
northwest and move southeast across the us. Once again, models are a
bit different with the overall synoptic pattern. Overall,
precipitation confidence christmas eve into christmas is moderate at
this time, with low confidence on exact timing or amounts. With the
holiday weekend and christmas, precautions for travel over mountains
should be taken.

Aviation
Light rain spreading across the northern mountains and N sac
valley through 06z Wed with lingering isolated showers thru 12z
wed before ending. Areas MVFR ifr conditions in rain showers with
fzlvl 7.5-9.0 kft and snow level 6.5-7.5 kft. Decreasing precip

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.
