Synopsis
Dry weather with locally breezy northerly winds expected through
the week.

Discussion
Upper high will continue to build over norcal early this week with
dry and warmer weather. Tightening pressure gradient between
yesterday's departing storm and the building high pressure will
lead to some increase in north wind overnight with a few gusts 15-20
mph. This will prevent fog formation tonight and Tuesday morning.

Winds will diminish Tuesday night Wednesday morning with a better
chances of fog formation during this time-frame.

.Extended discussion (Friday through Monday)
quiet weather is expected for the extended part of the forecast
due to an amplified ridge across the eastern pacific setting up
shop. Mostly clear skies may lead to early morning fog most
mornings, which will then be followed by warmer than normal high
temperatures each day. Forecast highs for the valley each day will
be in the 60s, with the upper 40s and low 50s being seen at
higher elevations. Low temperatures will generally be around
climatological values.

Aviation
Vfr conditions are expected through the period as high pressure
will build over the region.

Sto watches warnings advisories
None.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
