Synopsis High pressure will weaken and shift east during the
next couple of days. This will result in increased onshore flow
and a cooling trend across the area. Temperatures will lower to
near seasonal normals by Tuesday, with little change through the
week. Dry conditions will continue.

Discussion
A high pressure ridge over the region helped to push temps several
degrees above normal again yesterday, with 105 degree highs
recorded at both fresno and bakersfield. This ridge is progged to
weaken and slide eastward as a mid upper level trough settles
toward northern ca. The result for central ca will be an increased
onshore flow and a downward trend in temperatures during the next
couple of days. Highs today are progged to be generally around 2-5
degrees lower than yesterday but still reaching triple digits in
much of the sj valley to the south of merced county, as well as
in the desert zones. As temperatures continue to trend downward
Tuesday, most locations should top out around climo, though still
could see a few triple digits in the warmer south end of the
valley.

While the low pressure trough slowly lifts out of northern ca
Wednesday, additional shortwave energy moving into the northwest
coast maintains a troughy pattern to our north with the ridge
remaining to our east and south. In the resultant southwesterly
flow across our area we will see little change in temperatures, as
we hover near seasonal averages into next weekend. The increased
onshore flow will provide some breezier conditions during the
week, especially through and below mountain passes, but no
advisory level gusts are anticipated.

As the ridge retreats today, models drag some moisture northward
across southern ca but keep it out of our area. This being the
closest approach of moisture to our zones as the dry southwesterly
flow sets in, there is no precip in our forecast throughout the
period.

Aviation
Local MVFR visibility in haze can be expected in the san joaquin
valley. Otherwise,VFR conditions will prevail across the
central ca interior during the next 24 hours.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
