Synopsis Smoke will continue to impact the region through at
least early this week with dry conditions and light offshore
winds. Seasonably mild, dry conditions will then persist through
much of the week and into the upcoming weekend. A pattern change
will potentially bring rainfall to the region around thanksgiving.

Discussion As of 01:00 pm pst Monday... Not a lot has changed
from this morning - heavy smoke continues to blanket much of the
region with moderate to unhealthy air quality. The smoke is also
impacting temperatures and have adjusted many locations a few
degrees downward to due decreased sun.

Only minor day to day changes are expected with the over sensible
weather for much of the upcoming week. High pressure aloft will
gradually shift eastward and weaken roughly midweek. In the short
term, smoke will continue to impact much of the region keeping
temperatures slightly cooler. The extent of smoke coverage is a
little tricky as a lot will depend on how much smoke is produced
from the camp fire and minor shifts in the surface winds.

Overnight lows will continue to drop to in the 30s at night for
interior valleys. Current forecast will include some patchy frost
for locations colder than 33 degrees, but not widespread enough
for a frost advisory.

The million dollar question continues to be, where's the rain? It
seems like the longer range models have been fine tuning a pattern
shift, but keep kicking it farther down the road. The last few
days the targeted pattern shift has been early next week into
thanksgiving. The latest 12z model suite still shows this thinking
with a trough and possible rain next week. However, the GFS and
ecmwf are at odds with details and timing. Conf still remains low.

None the less, latest official seven day forecast will bring some
light rain to the north bay late Tuesday with slightly cooler
temps. CPC 8-14 day outlook is now showing higher than normal
chance for a wetter pattern as well for ca. Stay tuned.

Aviation As of 4:19 pm pst Monday... MVFR-ifr in smoke and poor
to very poor slant range visibilities through the period. Light
offshore winds tonight and Tuesday morning except gusty in the
salinas valley Tuesday morning. Large scale offshore pressure
gradient weakens Tuesday allowing weak onshore wind to develop by
afternoon. A sharp 500 mb ridge becomes replaced by a dry 500 mb
trough Tuesday, divergence in jet stream winds brings increasing
high clouds tonight and Tuesday.

Vicinity of ksfo... MVFR in smoke. Poor to very poor slant range
visibility. Light offshore wind becoming onshore 5-10 knots Tuesday
afternoon and evening.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... MVFR in smoke. Poor to very poor slant
range visibility. Winds settle to light offshore this evening
except gusty e-se winds in the salinas valley Tuesday morning.

Marine As of 3:54 pm pst Monday... Generally light to moderate
southerly winds will continue through tomorrow as a system passes
by to the north. Winds will become northwesterly again around mid-
week as high pressure builds back in over the eastern pacific.

Light mixed swell will continue through mid-week before a
northwest swell arrives.

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.
