Near the surface, weak diurnal flow will prevail through Sunday.

Forecast-wise, the short term period should definitely be rather
quiet. For today, clear skies will prevail across most areas
although there will be some morning clouds across north-facing
slopes of the mountains. With the clear skies, temperatures will
be quite cold this morning and current freeze warnings will remain
in effect until 800 am for the central coast as well as the
valleys of ventura and los angeles counties. For this afternoon,
temperatures will be a few degrees warmer, but still remain
several degrees below seasonal normals. As for winds, there may be
some locally gusty northeasterly winds this morning, but speeds
should remain well below advisory levels.

For tonight Saturday, mostly clear skies will continue. Air mass
will still remain quite chilly tonight Saturday morning with
temperatures remaining in the mid 20s to mid 30s. So another round
of freeze warnings or frost advisories may be needed for some
areas although areal extent of sub-freezing temperatures should be
less tonight. By Saturday afternoon, temperatures will continue to
exhibit a slight warming trend for all areas. Weak diurnal flow is
anticipated with any northerly winds tonight Saturday morning
remaining well below advisory levels.

For Saturday night Sunday, there will be an increase in high level
clouds with partly to mostly cloudy skies likely during the day on
Sunday. However, based on model qpf, no chance of any rain. Air
mass will continue to moderate on Sunday and afternoon high
temperatures will continue to exhibit a warming trend with most
coast and valley locales in the lower to mid 60s.

Long term (mon-thu) 22 251 am.

For the extended period, 00z models continue to exhibit good
synoptic agreement. At upper levels, ridge will gradually build
over the west coast, peaking in strength on Thursday. Near the
surface, weak diurnal flow will continue through the period.

With this pattern, relatively quiet weather is anticipated through
the period. As the upper level ridge develops, it will be somewhat
on the dirty side as some mid high level clouds will be around the
ridge. There is a weak system that rides up and over the ridge on
Wednesday, but may graze san luis obispo county with the threat of
some light precipitation. Otherwise, the extended period is
anticipated to be dry. As for temperatures, the warming trend will
continue for all areas with temperatures potentially a degree or

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.
