Synopsis Dry and seasonably cool weather can be expected
through the weekend. The next system will bring rain chances late
Sunday night through Monday, mainly across the north bay.

Additional rainfall is possible at times in the north bay for
much of next week, but most of our area will likely see dry and
warm weather.

Discussion As of 3:00 am pst Saturday... Cool conditions this
morning with many places at this hour in the 30s and 40s. In fact,
many spots over the north bay have dropped into the lower 30s and
could see another degree or two drop by sunrise. Still waiting for
fog to form over the north bay, although that may be very limited.

The cooler conditions will also lead to patchy frost.

A building ridge of high pressure will combine with an offshore
flow to bring dry weather to our entire CWA both today and
tomorrow. Highs will be in the upper 50s to the mid 60s with lows
Sunday morning forecast to be close to this morning's values.

Patchy frost will again be possible.

The synoptic patter will undergo a change as a moist flow takes
aim on the west coast. Models over the past few days have been
trending drier by pushing the moisture farther to the north as a
ridge of high pressure builds along the coast from the south. This
will lead to the bulk of the rain staying to our north with the
southern extent into a portion of our cwa. Although there remains
disagreement on the southern extent of the rain plus which day,
there is general agreement that for most of next week
precipitation will be possible over the north bay with
diminishing chances heading to the south. Definitely possible that
much of our CWA stays dry for all of the days.

Rainfall amounts by Friday will range from 1 4" to 3 4" for the
north bay to near zero for the southern third. Locations around
san francisco bay can expect 0.05" to 0.15". Temperatures will
also be warmer -- 60s and 70s.

Longer range outlook does bring a major atmospheric river into our
region for the remainder of the month.

Aviation As of 3:45 am pst Saturday... Surface high pressure
over the great basin will provide dry northerly flow forVFR
conditions. The only thing to watch for is the possibility of
morning fog at sts.

Vicinity of ksfo...VFR. Light offshore winds becoming west-
northwest after 20z.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR.

Marine As of 3:45 am pst Saturday... High pressure over the
great basin will weaken Sunday as a frontal system approaches the
pacific northwest. Light offshore winds through Sunday. Winds will
switch to southerly over the northern waters Sunday night and
Monday then increase on Tuesday. Winds over the southern waters
will remain light to moderate northwest.

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.
