Synopsis
Rain and mountain snow returns tonight and Friday. Sierra snow
impacts likely late tonight into Saturday. Another system possible
Sunday and Monday with mountain travel impacts. Brief break in
precip mid weekend but more precipitation early next week.

Discussion
Pacific storm system now approaching the coast will move into
norcal late tonight bringing a return to precipitation. The
heaviest amounts will fall during the day Friday. Valley rainfall
amounts will range from 1-2 inches redding area to 0.25-0.50
stockton/modesto. Mountain precip amounts will be 1-2 inches
liquid. Snowfall amounts 8-14 inches above 4500 feet with up to
two feet highest elevations. Expect significant travel delays over
the sierra. Activity will turn more showery Friday afternoon with
mesoscale models showing thunderstorms over the northern
sacramento valley. Tightening pressure gradient will bring a few
40 mph south wind gusts up the sacramento valley... Stockton to
redding... Strongest central valley around red bluff.

Models continue the trend of drier weather Saturday with weak
ridge northwest flow. Next system will drop through norcal Sunday
afternoon through Monday and looks to be slightly drier but colder
than Friday system. Snow levels look to be 4000 feet or lower.

.Extended discussion (Monday through Thursday)
showers will linger on Monday as upper level wave moves through.

Have boosted snow amounts a bit during the day with snow levels
around 5000 feet. Modest additional accumulations likely but will
probably be enough to cause a few travel delays. Have also
introduced the possibility of thunderstorms during the
afternoon/evening hours. This will hinge on the amount of clearing
in the morning but models are indicating some decent instability.

Ridging then builds in for Tuesday and Wednesday with warming
temperatures. Models continue to show another system dropping into
the area from the gulf of alaska on Thursday but disagree on the
details. At this time, best chances for precipitation looks to lie
across northern and eastern portions of the area.

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.
