Synopsis
A cold weather system dropping into central california from
the north will bring low elevation snow to the mountains and
foothills tonight with a chance of mainly light rain to the
san joaquin valley. Gusty winds will continue over the kern
county mountains and desert areas through tonight. Freezing
temperatures are forecast across much of the sj valley Friday
night. Dry weather is expected over the weekend then another
cold storm system arrives on Monday.

Discussion
Satellite imagery shows a long wave trough over the western
conus with a short wave diving down over northern california.

Shower activity thus far has mainly been confined to the sierra
nevada from yosemite np to kings canyon np. Precipitation has
been very light with amounts generally less than a tenth of an
inch. Snow levels around 4000 feet with some flurries into the
foothills around 3500 feet. Strong, gusty winds have developed
over the kern county mountains and desert where a wind advisory
is in effect.

The S WV will dig southward overnight bringing scattered showers
down into kern county as well. Moisture is limited and the focus
of precipitation will remain over the mountains due to orographic
enhancement. Rainfall in the sj valley will be rather sparse with
generally only trace amounts to a few hundredths of an inch. The
foothills will generally see from one to two tenths of an inch.

Snow levels will fall down to around 1500 feet this evening and a
winter weather advisory is in effect for the sierra foothills from
6 pm this evening through 6 am Friday morning. A winter weather
advisory is in effect for the kern county mountains from 10 pm
tonight through 10 am Friday. Snow amounts of up to 2 inches will
be possible in these lower elevation areas and could cause some
hazardous driving conditions, especially in the heavily traveled
mountain passes in kern county. The bulk of the activity will be
over by sunrise Friday, but a few light showers could continue
over the mountains foothills into the afternoon.

The trough will exit over the four corners region Friday night and
a very cold air mass will settle in over central california. Winds
will be light and clearing skies should set the stage for freezing
temperatures across much of the sj valley. Some rural areas could
drop into the upper 20s for a few hours. A freeze watch remains in
effect for Friday night into Saturday morning.

Dry weather will prevail this weekend though there is a very small
chance of a few light showers over the high sierra Saturday night
as a S WV trough dives over the great basin. Medium range models
continue to show another trough dropping south from western canada
on Monday. It generally appears similar to the current system but
a little farther to the west. This could potentially spread some
higher moisture over the area for a little better precip amounts.

Looking farther out, models indicate a wetter system possible next
Thursday into Friday.

Aviation
Mountain obscurations over the southern sierra nevada and kern
county mountains in low clouds and showers thru Fri afternoon.

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.
