Synopsis
High pressure will remain over the region for the next several
days. This will result in a continuation of dry conditions with
slightly above normal temperatures for the central california
interior.

Discussion
Blocking high pattern still dominating the west coast and is
currently in the form of a rex block. Visible satellite imagery
showing higher clouds streaming northward from an upper low off
the baja california coast while additional clouds ride over the
ridge through canada and the pacific northwest. The orientation of
the rex blocking pattern did provide the area with slightly
stronger winds today as the position of the high over low gave
southern california good east winds. Satellite imagery picked-up
on these east winds as they showed the smoke plumes from the
southern california fires continuing to blow offshore. Beyond
changes in the east wind speeds in the short term, little change
is expected over the central california interior for most of the
coming week.

The atmosphere remains very dry over the region as many dew point
values in kern county were only in the single digits. Therefore,
with a dry atmosphere, will expect another cold night with
overnight low hovering just above the freezing mark. In addition,
the smoke that has been pushing offshore has wrapped around and
moved into northern california. While not in significant amounts,
enough particulate matter has floated into the region to produce
hazy conditions across the san joaquin valley. The worst of the
haze will occur around sunrise as visibility values drop to around
1 to 2 miles for a few hours. Afterward, will expect mild
conditions with plenty of sunshine.

Models still showing a disturbance riding over the ridge pattern
and into the great basin by mid-week. At this point, models are
not longer consolidating the weak disturbance with the upper low
over the baja california region. Therefore, while the east winds
will continue through mid-week, winds may not become strong around
the mid-week period and the ridge pattern continues to dominate
the west coast. Yet, later in the week, models attempt to flatten
the ridge pattern as a strong disturbance pushes onto the west
coast (closer to the pacific northwest) near the Friday time-
frame. Currently, models showing some uncertainty in the amplitude
of the disturbance during its passage on Friday. In addition,
models keep central california dry on Friday with only clouds
possible and a slight change in temperature. At this point, will
opt to keep the region dry for the next seven days as confidence
in the possible solution remains low on what models are attempt to
do by day seven.

Aviation
Widespread MVFR visibility in haze and mist will persist in the san
joaquin valley, with areas of ifr and local lifr vlifr in fog
developing between 03z and 18z mon. Otherwise,VFR conditions will
prevail over 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.
