Synopsis
A system will move through the region beginning today increasing
chances for precipitation through Saturday and bringing cooler
temperatures. Dry conditions will return late Saturday through
Sunday. Precipitation chances will again be increased beginning
Monday.

Discussion
The san joaquin valley fog pattern in place the last several days
will be interrupted with a system moving into central california
beginning today. This will not be a blockbuster of a storm,
however it will bring the region some needed precipitation. The
majority of the precipitation will fall over the higher elevations
of the sierra nevada as the main drive will be orographical in
nature. As the westerly flow to the south of the low pressure
system centered over northern california moves southward the
moisture streaming into the system will begin to first drop in
the highest elevations near yosemite. Winds will be gusty above
6000 feet. Snow levels will begin very high around 9500 feet today
and will drop to around 5000 feet by Saturday morning as the
trough moves southward. Snowfall will be moderate with many
locations above 6000 feet seeing 5 to 10 inches and localized
amounts of around a foot will be possible. Especially near the
crest areas. Mountain snowfall will trend less the further south
you go along the ridge. Therefore opted to just include the areas
from yosemite to tulare county in the winter weather advisory that
is in place from 10 am today until 4 am Saturday. Precipitation
across the sjv will remain on the light side and amounts less than
a quarter of an inch will be the rule rather than the exception.

The main question with the upcoming system will be how far south
the trough will drop. This is where the forecast becomes tricky as
if the low moves eastward quicker than expected the kern county
mountain areas may not see much. Therefore, the bust potential is
high for this part of the forecast. We have held off on hoisting
any products for the meantime and will allow the day shift a
chance to monitor and fire when it sees the whites of its eyes. If
the storm moves further southward, snowfall in the higher
elevations of the kern county mountains will be possible and could
make a mess of the grapevine and tehachapi passes.

A break in the action will take place on Sunday when chances will
once again be increased beginning Monday as another weak system
skirts the area. Amounts at this time are expected to be on the
light side.

Aviation
Widespread ifr and lifr conditions until 19z today. Afterward, areas
of MVFR conditions in clouds and mist haze with patches of ifr
conditions persisting over the san joaquin valley.VFR MVFR
conditions over the higher terrain of the sierra nevada will become
ifr with mountain obscuration in clouds and precipitation after
00z Friday. Elsewhere,VFR conditions will prevail during the next
24 hours.

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.
