Low pressure will remain over the area today with continued
showery weather. Brief high pressure will build tonight and Friday
for a dry period then another weather disturbance will move
across northern california on Saturday for another threat of
precipitation. High pressure with dry weather rebuilds for the
late weekend through Monday.
Lingering spotty showers continued today across central california
as a disturbance moving through southern california kept the area
unsettled. Upper air analysis and satellite imagery showed the
upper low still moving ashore this afternoon and headed through
the south- land with wrap-around showers forming over the southern
portion of the district. While weak instability is being shown
across central california, the best instability for the production
of thunderstorms favors the mojave desert today. Therefore, will
expect convective showers over the area with a minimal potential
of the showers turning into thunderstorms across the kern desert.
Current thinking agrees with storm prediction center of keep
thunderstorms out of central california and more over the desert
southwest. Otherwise, the central california interior saw cooler
conditions with variable cloud cover ahead of clearing expected on
Friday. Therefore, will see showers diminish overnight as the
region will see a brief quiet period ahead of the next storm
headed for california this weekend.
Short range models progging the next storm to hit california at
the start of the weekend as even more precipitation will falls
across the region. Timing has the precipitation entering the
region later Friday afternoon and approaching central california
closer to the evening hours. While most of the day on Friday will
remain dry, model uncertainty has precipitation starting as early
as 5 pm on Friday with better possibilities of precipitation
starting a hours before 10 pm that evening. The precipitation will
the overspread the region Friday night with the heaviest
precipitation falling before sunrise Saturday morning. However,|
the trajectory of the disturbance favors northern california with
the southern edge hitting central california. This will translate
in the bulk of the moisture affecting northern california with the
district seeing light to marginal precipitation amounts. Also,
the southern edge will be a quick hit of moisture with the storm
exiting the area by Saturday evening.
By Sunday morning, cool air will surge into the region after the
fall of light snow accumulating down to near 5000 feet. Yet,
Sunday may only see lingering spotty showers with clouds banking
up along the east side of the san joaquin valley and down near the
grapevine. While the day will remain mostly dry, another storm
will be heading for california. Showing a similar track to the
weekend storm, this next storm will also favor northern
california as mostly light precipitation is progged for the
Tuesday and Wednesday time-frame. Again, uncertainty in the
initial timing of the storm could have it arrive late Monday
night, but, will favor the onset of precipitation occurring on
Tuesday. After the mid-week storm, model confidence lowers as a
ridge pattern begins to form over the eastern pacific. Yet, the
west coast remains under the cyclonic flow pattern as unsettled
conditions could exist through at least the next seven days and
beyond. Looking beyond the seven days, more storms could
california as the wet extends into the beginning of april.
Areas of mountain obscuring ifr will continue across the southern
sierra nevada and tehachapi mountains until 10z fri. Local MVFR
conditions in low clouds in the san joaquin valley and southern
sierra foothills. OtherwiseVFR 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.
