Synopsis Building high pressure along the west coast will result
in a gradual warming trend through Saturday, along with mainly
clear skies. The dry weather pattern will likely last through the
end of the month, with a continuation of seasonably mild days and
cool nights.

Discussion As of 8:50 pm pst Tuesday... Early evening
temperatures are running close to what they were 24 hours ago, and
surface dewpoints are lower in most locations. Thus, expect
another cool night tonight with patchy frost likely in some of the
colder inland valleys by daybreak Wednesday.

An upper level ridge is forecast to continue amplifying offshore
along 130w through the end of the work week, and then shift inland
over california during the upcoming weekend. This will mean
continued dry weather across our region, along with mostly clear
skies and a warming trend. Nights will continue to be chilly due
to clear skies and light winds, but daytime highs are expected to
warm anywhere from 5 to 10 degrees above normal by the weekend.

Highs will mostly be in the 60s, with a few lower 70s likely from
the southern santa clara valley southward by Friday and Saturday.

Little change is forecast through at least the first half of next
week, and probably through the end of january. The models agree
that a dry pattern will persist, although there are indications
the ridge may retrograde offshore a bit, resulting in slight
cooling. Farther down the road, the models are indicating the
ridge may begin to break down by the end of next week. However,
exactly how the pattern will evolve is difficult to say as there
are various scenarios being forecast by different models and by
various model ensemble members. But there is at least a chance
that wet weather may return within the first few days of february,
or as soon as late on january 31st if the 12z ECMWF verifies.

Aviation As of 9:30 pm pst Tuesday... For 06z tafs. High
pressure will maintain mainly clear skies across area terminals
with the exception of a few high clouds. Generally light winds
will prevail through the forecast period.

Vicinity of ksfo...VFR conditions will prevail through the period
with only a few high clouds expected. Light to locally variable winds
will persist.

Sfo bridge approach... Similar to sfo.

Monterey bay terminals...VFR conditions and light winds will
prevail through the period.

Marine As of 8:41 pm pst Tuesday... High pressure over the
eastern pacific will maintain light to moderate northerly winds
across the coastal waters through much of the week. Locally breezy
winds possible Wednesday afternoon and evening along the big sur
coast, south of point sur. A series of small to moderate northwest
swells are forecast throughout the week.

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.
