Synopsis Above normal temperatures will continue today then
trending much cooler through Friday as a storm system moves over
northern california. This system will bring a chance for light
precipitation Thursday night and Friday along with an increase in
winds. Dry weather will return this weekend with a warming trend
into early next week.
Discussion Satellite imagery shows an upper disturbance still
passing over central california early this morning. Khnx radar is
detecting some weak echoes across the southern san joaquin valley
but no precipitation is occurring. The moisture remains in the
mid levels as regional ASOS observations are clear below 12k feet.
The short wave will shift east of the area this afternoon with
diminishing cloud cover. Otherwise, temperatures will again climb
to around 4-8 degrees above normal this afternoon.
A sharp pattern change will occur to end the work week as an upper
trough drops down from the gulf of alaska. The models continue to
keep the bulk of the moisture and dynamics to our north, but there
is a chance for some light precipitation. Conditions should remain
dry through Thursday afternoon then a slight chance of precipitation
arrives in yosemite np in the evening. Chances increase and spread
south overnight into Friday morning. The trough axis is expected to
quickly shift east by Friday afternoon with just a few lingering
upslope showers possible in the tehachapi mountains and foothills.
Rainfall will be light with QPF generally less than a tenth of an
inch. Snow levels will start out around 10000 feet then lower to|
near 8500 feet in yosemite np Friday morning. Snow amounts should
mainly be from a dusting to one inch.
Winds will begin increasing on Thursday as the onshore pressure
gradient ramps up. Gusty winds are expected through and below the
passes in eastern kern county and could reach advisory levels on
Friday. Breezy conditions will develop in the san joaquin valley
as well on Friday. Winds will diminish on Saturday.
Temperatures will lower to near normal on Thursday then several
degrees below normal on Friday. The cooler air mass will not last
long as strong high pressure begins to build in from the pacific.
Highs are forecast to be back near normal by Sunday then several
degrees above normal early next week.
Areas of MVFR visibilities due to smoke and haze can be expected
in the san joaquin valley, southern sierra foothills and higher
elevations of the southern sierra nevada for at least the next 24
hours, withVFR conditions prevailing elsewhere across the central

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.
