329 pm pst Wed nov 14 2018

Synopsis Smoke and haze continue to impact much of the bay area
while dry and seasonable weather persists elsewhere. No big
changes in the weather through the end of the work week with some
signs of less smoke and slightly cooler temperatures over the
weekend. Dry conditions persist at least through Tuesday with
possible pattern change by the middle of next week.

Discussion As of 2:56 pm pst Wednesday... Smoke from the camp
fire continues to be one of the main impacts on bay area weather.

Satellite showed another belch of smoke this morning that has
worked its way down the sac valley and into the bay area.

Gradients show a half millibar offshore from sac to sfo with east
winds blowing in the delta and bringing the smoke westward into
the bay area. Visibility is now less than a mile in livermore with
the east bay indicating some of the poorest visibility. Hazy
skies continue elsewhere with afternoon highs generally in the 60s
with 70s for the central coast. Very dry conditions continue this
afternoon with many sites reporting humidity values in the single
digits including usually wet spots such as big sur coming in at
9%
day over day changes in the large scale weather remain minor with
daytime highs in the 60s and 70s with fairly cool overnight lows
from the mid 30s to mid 40s through the end of the work week.

Million dollar question is how active the camp fire will burn the
next few days. As was shown today with lighter winds and even
light offshore flow the smoke will tend to drift towards the bay
area until we get a shift in the large scale weather patterns.

That may occur by this weekend as an upper low approaches the
southern california coast and some type of southerly flow may help
to keep any smoke to our east. It should be noted that latest
trends build a ridge over northeast california over the weekend
that will keep warm and dry weather up there with a fairly strong
low level inversion likely in place, not ideal for smoke
dispersion.

Long range forecast details regarding any rainfall next week
continues to be watched. The 12 and 18z GFS deterministic runs
have been discouraging and gone completely dry. Need to note that
the ensembles still show a trough along the west coast weds
through Friday of next week. The ECMWF has a weak front on weds
and a second stronger storm by about next Friday. This is all
still 7-10 days out so confidence remains low on details as we
anxiously await a pattern shift. Until then mild and dry weather
for at least another 6 days.

Aviation As of 03:29 pm pst Wednesday... For 00z tafs. Much of
the area continues to see reduced visibilities to MVFR, with
isolated instances of ifr, due to smoke. Generally poor vis is
expected to continue with slant range visibility issues persisting
through the period. Light winds will continue through the period
as well.

Vicinity of ksfo... MVFR vis due to smoke with generally light
winds. Slant range vis issues expected to persist. Latest hrrr
smoke forecast does not suggest much change in smoke conditions
through at least tonight.

Sfo bridge approach... Similar to terminal.

Monterey bay terminals...VFR prevailing with periods of reduced
vis to MVFR due to smoke.

Marine As of 02:26 pm pst Wednesday... Predominately light north
to northwest winds across the waters through the end of the work
week. Locally breezy winds will exist near coastal gaps and
favored coastal jet areas. Light mixed swell today with a new
northwest swell arriving tomorrow.

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.
