Synopsis
Freezing temperatures will occur across much of the san joaquin
valle tonight with rural areas falling into the upper 20s and
possibly near 25 degrees in a few locations. Dry weather and a
warming trend will occur this weekend then another cold storm
system arrives Monday for more precipitation and increased winds
into Tuesday.

Discussion
Upper trough is exiting to the east over the four corners region
with a cold northerly flow aloft across central california. Some
fairly good snowfall amounts occurred last night over the sierra
nevada and even into the adjacent foothills. Generally, reports
were from 2-6 inches, but a few high sierra locations received up
to 10-12 inches. Some light upslope showers have been developing
through the day, mainly along the tulare county foothills. These
showers will end with sunset and clouds will mostly dissipate. An
upper jet as well as an onshore surface pressure gradient has been
producing gusty winds across the san joaquin valley, generally in
the 20-30 mph. Gusts in the kern county mountains and desert have
been in the 30-40 mph range. These gusts will rapidly diminish
after sunset with light winds prevailing overnight.

A very cold air mass is in place, and with the clearing skies and
light winds overnight, a freeze warning is in effect for the san
joaquin valley tonight into early Saturday morning. Many rural
areas will fall into the upper 20s by morning and a few locations
could bottom out near 25 degrees for an hour or two.

Dry weather will prevail this weekend though a disturbance moving
over the great basin Saturday evening could bring a few isolated
light showers to the high sierra from yosemite np to kings canyon
np. Little if any rain snow accumulation is expected regardless.

Another cold storm system is expected to drop down from the north
on Monday into Tuesday bringing more precipitation and gusty winds.

The models want to track this next system a little farther west
down the coast than the last one. This could provide better rain
amounts for the sj valley and current QPF generally has around a
tenth of an inch. The mountains are looking at a quarter to half
an inch qpf. Snow levels will again fall into the foothills, down
near 2500 feet. Gusty winds will develop as well and could reach
advisory level in some areas, most likely the kern co mtns desert.

Medium range models are struggling a bit with another potential
storm system later next week. While not as impressive as it once
was depicted, it could still be a more significant precipitation
producer, including for the sj valley. Current timing focuses on
Thursday and Friday of next week.

Aviation
Mountain obscurations over the southern sierra nevada and kern
county mountains in low clouds thru Fri evening and over the high
sierra Saturday afternoon. OtherwiseVFR conditions expected across
the remainder of the central ca interior 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.
