Synopsis High pressure will bring dry and warmer weather to
the area Tuesday and Wednesday. The high will move east on
Thursday with the next chance of rain late this weekend.

Discussion As of 3:00 am pst Tuesday... The warm front that
brought rain to the north bay has lifted north as upper level high
pressure over southern california strengthens and builds north.

This will lead to a big warmup in temperatures today through
Wednesday. Highs will be in the upper 60s and 70s across the sfo
bay area with 70s to lower 80s in the southern part of the cwa.

Temperatures on Wednesday will be a couple of degrees warmer than
Tuesday and will be the warmest day of the week. We will be under
a southwesterly flow so nighttime temperatures will remain quite
mild.

The ridge will start to flatten on Thursday as an upper level
shortwave moves through the pacific northwest. Temperatures
should cool off slightly and there is a slight chance of rain
reaching far northern sonoma county on Thursday. Partly cloudy but
dry conditions are expected for Friday and Saturday as the ridge
moves a little further to the east.

A weather system will bring a chance of rain to at least the
northern part of the CWA on Sunday. This is consistent with the
gfs solution while the ECMWF is wetter and brings rain chances to
much of the cwa.

Aviation As of 03:44 am pst Tuesday... For 12z tafs. Currently
vfr across most sites as mid to high level clouds continue to move
over the area. So far not seeing signs of lowering cigs, with the
exception of ksts. Therefore, keeping the CIGS at koak and ksfo
vfr for now. With the air still relatively moist, visibilities
may go down to MVFR at times early this morning due to haze. Winds
will remain generally light through the period at around 10 kt or
less.

Vicinity of ksfo... CIGS have remained above 10000 ft so far
tonight, so the tempo group for low cloud bases has been removed
from the 12z taf. ExpectingVFR conditions to prevail this
morning with possible MVFR vis due to haze. E-se winds will
continue into the morning before switching to northwest this
afternoon.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR conditions expected to prevail with
mainly light e-se winds this morning. Ksns may see winds up to 10
kt. Winds are expected to turn w-nw this afternoon but remain
light.

Marine As of 02:17 am pst Tuesday... As a ridge builds in from
the south, a split windflow pattern is developing, with winds out
of the north over the southern waters and out of the south over
the northern waters. Winds will remain generally light with more
moderate winds in the far northern waters. Chances of rain will
return to the northern waters towards the end of the week. West to
northwest swell will increase mid-week.

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.
