Synopsis Widespread smoke and haze will continue to result in
poor air quality over much of the san francisco bay area through
the weekend. Otherwise, dry weather with mild temperatures are
forecast to persist through early next week. A significant pattern
change appears likely starting around the middle of next week,
with the potential for widespread periodic rainfall during the
second half of the week.

Discussion As of 02:52 am pst Friday... The main impacts across
the region in the short-term will continue to be smoke, haze and
associated poor air quality as a result of the camp fire inland to
our north. Poor visibility, below 1 1 2 sm at times, is being
reported across the greater san francisco bay area with
temperatures ranging from the middle 30s in our colder inland
valleys to upper 40s near the coast. Given the weak offshore flow
aloft, air quality is not forecast to improve much through the day
with unhealthy to very unhealthy conditions forecast (by the bay
area quality management district) across the bay area while
slightly better conditions are expected over the monterey bay
region.

The forecast models do indicate a slight increase in onshore flow
near the coast this weekend which may help to improve conditions.

May even see areas of low clouds develop over the pacific late
tonight with the potential for coastal intrusion by Saturday
morning. Something that will need to be closely monitored as smoke
may actually get trapped beneath the low level inversion.

Regardless, dry weather conditions will persist along with
temperatures above seasonal averages each afternoon through the
weekend and into early next week. Overnight conditions will be
seasonably cool, especially inland away from the coast.

Forecast confidence continues to increase regarding a major pattern
shift late next week that would bring unsettled weather conditions
to the region. An initial upper level system is forecast to develop
over the eastern pacific and approach the southern california coast
early next week, missing our region. However, the medium range
models are in better agreement with subsequent systems approaching
the region during the second half of the week. The gfs, ECMWF and
canadian are in decent agreement with the potential for widespread
rainfall developing over the region as early as Wednesday.

Additional systems appear likely to impact the region around
thanksgiving and potentially into the following holiday weekend as
well. With this said, timing and strength of each system remains
difficult to pin-point at this time given model-to-model and run-to-
run differences. Regardless, a more active pattern is appearing more
likely late in month which would also help to improve air quality
region-wide.

Aviation As of 4:08 am pst Friday... MVFR-ifr in smoke. Mainly
light winds. Poor to very poor slant range visibilities.

Vicinity of ksfo... MVFR-ifr visibility in smoke, light wind. Poor
to very poor slant range visibility.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... MVFR visibilities in smoke, light winds
except SE 5 to 10 knots in the salinas valley this morning.

Marine As of 2:52 am pst Friday... Generally light winds will
continue through the weekend and early next week. A mixed moderate
northwest swell and light southerly swell will also persist. Wet
weather develops by the middle of next week.

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.
