Update Updated air quality issues.
A system will move through the region tonight increasing chances
for precipitation through Saturday and bringing cooler
temperatures. Dry conditions will return late Saturday through
Sunday. Precipitation chances will again increase beginning
Monday, though for locations mainly north of kern county.
Discussion The low pressure system is slowly moving southward.
The main effects at this time are mid-level and high clouds. The
low clouds from this morning have mainly dissipated due to the
arrival of the southwest flow ahead of the system and higher
level cloud cover. So far this afternoon, radar has been showing a
few light echoes over western merced county, so it is possible a
few sprinkles could be reaching the ground. The associated upper-
level trough with this system and the colder air remains off the
coast of northern california and is expected to dig southward and
move inland during the day on Friday.
Snow levels are expected to fall during the night tonight and
continue falling through the day on Friday as the cold front moves
southward over central california. Most of the precipitation is
expected occur over the sierra nevada overnight tonight into
Friday, and most of the snow will fall mainly above 5,000 feet.
However, a dusting is possible in few locations down to 3,000 feet
by Friday afternoon, especially in showers behind the cold front.
As the system continues its progression southward, snowfall is
expected over the kern county mountain passes during Friday
through Saturday, with most of the activity occurring on Friday
afternoon and Friday night. Lingering snow showers, mainly above
3,000 feet will likely continue over the kern county mountains
through at least early Saturday afternoon due to the colder
northwest flow behind the system. Some snow accumulation is
possible at the pass levels, especially along the major highways
(including interstate 5 through the grapevine and tehachapi pass
along highway 58). Therefore, have issued a winter weather|
advisory for these areas in the kern county mountains. Based on
latest data, confidence in this pattern has slightly increased,
but remains medium, including in terms of amount of precipitation
and how low the snow will fall, beyond Friday afternoon.
After a brief break on Saturday evening Sunday, another low
pressure system is expected to move over at least the northern
part of our forecast area. There is a slight chance of showers
for areas north of kern county during Sunday night into Monday.
Based on latest guidance, this system appears to be not as cold,
while moisture is limited. In addition, the system will likely
weaken over our forecast area as it moves southward from northern
california. Snow is expected to fall mainly over the sierra nevada
from yosemite to kings canyon for elevations in the more typical
region, or around 5,000 to 6,000 feet.
It also appears another system could bring another round of
precipitation to central california late next week, as the models
for the last couple of runs have shown a similar pattern
developing. However, the typical disagreement in timing and
placement still exists between model solutions, so confidence
lowers significantly for that period.

nevada, spreading south to the tehachapi mountains after 12z Friday.
MVFR conditions in haze across the san joaquin valley with scattered

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.
