Synopsis
Series of weak storms will pass over norcal over the next several
days but precipitation and impacts will be minimal with each of
them. Valley fog will continue to be possible between systems.

Discussion Fog in the valley early this morning lifted into a
persistent layer of low cloud over most of the area and keeping
temperatures cool. Some mist will likely continue to linger into
the evening over valley locations from around marysville
southward. In addition to low clouds, high and mid clouds have
spread across the area ahead of an approaching trough and surface
cold front. These clouds should act to limit widespread dense fog
formation tonight, with areas of mist continuing and maybe some
local patches of fog developing near waterways.

The cold front is moving inland this afternoon, currently located
over humboldt, del norte and western siskiyou counties. This
front will continue to weaken as it moves inland to the southeast,
with a light band of precipitation moving into the forecast area
tonight. The northern coastal range and the northern sacramento
valley should see this band arrive in the late evening, spreading
into the central sacramento valley, lake county and plumas county
from around midnight to dawn. The delta and the sacramento metro
area and the i80 corridor should see precipitation around the
morning commute, to the south by early afternoon. Precipitation
duration and amounts should be fairly light with this narrow band,
generally around 0.10" or less of rain, around an inch or so of
snow in the mountains.

North winds will limit widespread fog chances Monday night-
Tuesday morning, though some patchy fog could develop on the more
sheltered east side of the valley.

The next trough will drop south through the pacific northwest
late Tuesday. The tail end will brush through norcal with a chance
of light precipitation for the northern coastal range, far
northern sierra and the southern cascades. The best lift and moisture
will remain well to the north in oregon and washington, with rain
and snow amounts remaining very light for our forecast area. Snow
levels with this system look to be between 4500 and 5500 feet,
though just a dusting is expected. Ek
.Extended discussion (Thursday through Sunday)
with upper level ridging over california Thursday, dry conditions
will persist until early Friday when a system is forecast to move
across the area. Models are still struggling with the timing for
this late week system with the ECMWF much slower than the gfs. The
ecmwf also GOES on to bring a closed low over the area Saturday,
while the GFS is relatively dry. Have continued with only chance
pops Saturday, before another round of precipitation is forecast
for Sunday. Overall, unsettled weather for the extended period.

Aviation
MVFR ifr visibilities south of krbl will continue until light
precipitation spreads south to about i-80 after 06z Monday.

Stratus is expected to persist through the day tomorrow, although
may lift toVFR near the end of the period.

Sto watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
