Synopsis A weak weather system will bring a chance of light
precipitation north of fresno county today. A stronger system
will bring rain and mountain snow to much of the area Wednesday
night through Thursday night. High pressure will build back over
the area by the weekend bringing dry conditions.
Discussion The cold front which has been approaching our area
has stalled out to the north of our area. While this system has
brought rain and mountain snow to much of norcal, the
precipitation has so far remained to the north of our area. This
system is expected to dissipate just top the north of our area and
might produce some light precipitation in merced and mariposa
counties as well as over yosemite national park.
Wrf indicating shortwave ridging over central ca on Tuesday.
Northerly flow ahead of the ridge will limit widespread fog
development tonight and only patchy fog is anticipated over the
san joaquin valley on Tuesday morning. By Wednesday some recovery
in temperatures is expected and afternoon highs will rise to
above seasonal normals.
A more significant system is progged to drop southeast out of the
gulf of ak on Wednesday and push through central ca on Wednesday
night and Thursday. While guidance has been backing off on
precipitation amounts with this system, it is still expected to
significant precipitation to our area with half an inch to an
inch of liquid precipitation expected for the southern sierra
nevada from kings canyon northward and a quarter to a half an inch
further south in tulare county. Meanwhile, the san joaquin valley
is expected to receive a quarter to half an inch of rainfall
north of kern county while the south end of the valley and the|
kern county mountains are expected to pick up between a tenth of
an inch and a quarter inch. Snow levels are expected to between
5000 and 5500 feet on Wednesday night lowering to 3000 to 4000
feet by late Thursday afternoon. Light snow will be possible over
the major passes in kern county Thursday afternoon and evening
which could adversely impact travel.
The medium range models and their ensemble means are in good
agreement with moving this system to the east of our area on
Friday as high pressure strengthens off the ca coast. The high is
expected to build inland over the weekend which will bring a
period of dry weather and slight above normal temepratures over
the weekend and into the beginning of next week. Some night and
morning fog will be possible in the san joaquin valley by this
weekend as clearing skies, light winds, inversion conditions and
residual low level moisture provide for better conditions for fog
Aviation Areas of MVFR and local ifr conditions possible in
showers, with mountain obscurations over the sierra nevada,
through 18z Monday for mainly fresno county northward. Areas of
MVFR and local ifr visibilities in mist developing in the san
joaquin valley after 09z Tuesday. Otherwise,VFR conditions will
prevail across the central ca interior for 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.
