Synopsis
A disturbance moving into southern california will help generate
strong easterly winds across much of the area. These strong
easterly winds are expected to blow across central california
through at least this Monday evening. Afterward, dry conditions
are expected to continue with temperatures remaining at near
normal values.

Discussion
Strong winds impacting the central california interior this
morning as wind gusts reaching 50 mph affect the area. Reports of
fallen trees across the mountains have been given from several
locations. Given the current wind speeds, a wind advisory is in
effect until around sunrise for the region from yosemite to kings
canyon. While winds are also blowing across the kern county
mountains, the wind advisory for that area will continue until
around sunset this evening. In addition, because of the trajectory
of the associated disturbance producing the strong winds, the path
of the disturbance will introduce little moisture into the region.

Therefore, the disturbance will remain dry with winds the main
impact affecting central california. Due to a blocking pattern
over the west coast, little change will occur over the region as
easterly wind flow will continue for several days.

The current disturbance associated with the strong winds is
progged to linger over the desert southwest as it become part of
an omega blocking pattern. While uncertainty exist on how the
pattern will evolve toward the middle of the week, will lean
toward keeping the center of the low near the four corners area
through early Thursday. This solution will place the axis of the
high pressure ridge just off the california coast and the district
under a north to northeasterly wind direction. By Friday, the
blocking pattern converts over to a rex block formation which may
allow for a northward surge of moisture into the region. At the
moment, will increase cloud cover for the latter part of the
forecast period (around Sunday - Monday) and wait until confidence
increases to introduce precipitation. Otherwise, will expect
temperatures at near normal values while a blocking pattern
dominates the area.

Aviation
Vfr conditions will prevail over the central california interior for
at least the next 24 hours. Windy east winds across the sierra
nevada and kern county mountains with LCL sfc wnd gusting over
40kts until 03z Tuesday.

Air quality issues
None.

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.
