329 am pst Sat nov 18 2017

Synopsis
Dry weather through Sunday. Next system moves through Monday with
another during mid week. Each of these next systems will come
with light to moderate precipitation and high snow levels well above
pass levels.

Discussion (today through Tuesday)
Model analysis and satellite wind fields showed an upper level
ridge of high pressure present over california overnight with dry
air over the interior. Observations were clear with valley
temperatures in the low to mid 40s.

Model forecasts are in agreement to the amplitude increasing on
the upper level ridge over the forecast area today before
transitioning to a zonal flow aloft Sunday. This will result in
dry weather with mostly clear skies across the region with high
temperatures right around normal for mid november.

The next weather disturbance will arrive Monday into Tuesday as
the upper level set up involves a high pressure ridge to the south
and a trough of low pressure to the northwest. As a result of the
upper wind circulation, moisture is anticipated to stream into the
west coast. The main brunt of moisture should pass to the north
into oregon, but light precipitation will occur Monday and
Tuesday. The ridge to the south should remain positioned enough to
keep the cooler air to the north, which will keep high snow levels
for the mountains at 10k feet and above.

.Extended discussion (Wednesday through Saturday)
forecast confidence remains low through the extended period. The
latest runs of the GFS and ECMWF continue a very strong ridge over
the west which favors limiting precipitation chances to areas
mainly north of interstate 80. Along with high snow levels,
impacts to travel around thanksgiving appear fairly minimal at
this time.

Aviation
MainlyVFR conditions with light north winds the next 24 hours.

Local MVFR visibilities in fog may develop south of ksac 14z-18z.

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.
