Update Updated air quality issues.
Synopsis High pressure will weaken and shift east early this
week as a low pressure center moves through the pacific northwest
on Monday and Tuesday. This will result in increased onshore flow
and a cooling trend across the area. Temperatures will remain
above seasonal normals however, and dry conditions will prevail
across the area this week.
Some cumulus clouds developing over the high sierra, otherwise
clear and dry conditions across the central ca interior. Some
smoke noted this morning along the san joaquin and tuolumne rivers
from local wild fires. Thus some local hazy conditions reported
this morning may likely happen again tomorrow morning towards the
merced and madera area counties. Temperatures running a bit cooler
in the N parts of the central valley. Otherwise a mix bag of
trends. Temperatures were 6-10 degrees above normal yesterday and
this warm trend is expected for another day as a ridge over S ca
begins a SE track towards az. As the ridge moves se, an upper
trough will start moving into N ca starting Monday with a couple
of additional disturbances following on Tuesday and Wednesday.
This will set up a dry SW flow aloft over most of central ca for
the forecast period. The one exception will be towards the mojave
desert area with the flow more S allowing some monsoon moisture to
mover across SE ca on Monday. However the high resolution models
maintain the potential convective precipitation east of kern
county. Models also prog the flow aloft to increasing and and
becoming S to SW Monday and continuing through mid week. This
should result in improving air quality due to wind direction|
increasing ventilation. In addition the increased onshore flow
into central ca will allow for a noticable cooling trend to take
place and high temperatures in the valley and foothills will lower
to seasonal levels on Tuesday.
The medium range models and their ensemble means are in fairly
good agreement with the low ejecting east into the intermountain
west region by the end of the week leaving a baggy trough
situated off the west coast. Interaction between this feature and
a building high over texas will result in a dry southwest flow
prevailing over our area for the remainder of the forecast period.
Little change in diurnal temperatures is expected while dry
conditions prevail under mainly clear skies from Thursday through
Areas of MVFR visibility in smoke and haze can be expected in the
foothills and higher elevations of the southern sierra nevada
along and north of the san joaquin river basin during the morning
until 18z. Otherwise,VFR conditions will prevail across 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.
