Synopsis Smoke and haze will continue to produce poor air
quality over much of the san francisco bay through late week. Dry
and mild conditions are also likely to persist through early next
week with the potential for slight improvement in smoky
conditions by the weekend as weak onshore flow returns. A more
significant pattern change appears likely during the latter half
of next week with the potential for widespread rainfall.

Discussion As of 9:25 am pst Thursday... Smoke from the camp
fire continues to adversely impact the district this morning,
especially around the greater san francisco bay area where
visibilities continue to fluctuate between 1 mile and 3 miles.

These conditions are resulting in poor air quality with no
significant improvement forecast through the weekend as weak
offshore low persists.

Day-to-day changes are minor through the upcoming weekend with
daytime temperatures warming into the 60s and 70s with overnight
lows in the middle 30s across the colder inland locations to
middle 40s near the coast bays. Very dry conditions are also
likely to persist, even near the coast through the weekend. Weak
offshore flow will continue to spread smoke over the region until
the large scale pattern aloft changes. Right now, this much-needed
pattern change isn't expected to occur until the middle of next
week, at the earliest. The 00z ECMWF has a weak frontal system
bringing rain to much of the area late next Wednesday, followed by
a stronger front on Friday. The 12z GFS holds off the first
system until thanksgiving, followed by another system on Friday.

The rainfall, along with stronger onshore flow, will help to scour
out the smoke from the area.

Aviation As of 09:50 am pst Thursday... For 18z tafs. Widespread
impacts from smoke, particularly for sf bay area and the
carquinez strait delta as offshore winds inland funnel smoke from
the camp fire in butte county towards the golden gate gap. Smoke
concentrations are particularly think around the east bay (ie kccr
klvk) and near the sf bay shoreline (koak ksjc knuq ksfo) as smoke
fans out and dams up after exiting the delta and before exiting
the golden gate gap. Expect ifr to MVFR visibilities at sf bay
area terminals with MVFR CIGS possible at some terminals due to
the wildfire smoke. Poor slant range visbys will impact arrivals.

Winds shift late Friday however smoke is forecast to linger in
place under a stagnant air mass with very weak winds. Smoke
impacts may continue until next storm system, slated for a week
out from now.

Vicinity of ksfo... Ifr to MVFR visibilities with MVFR ceilings due
to wildfire smoke through the duration of the TAF period.

Afternoon winds onshore 8 to 12kt.

Sfo bridge approach... Similar to terminal.

Monterey bay terminals...VFR conditions are generally forecast to
prevail; though, periods of smoke during the day could drop
visibilities to MVFR levels. Easterly winds in the morning at both
sns and mry will become onshore by the afternoon.

Marine As of 09:41 am pst Thursday... North to northwest winds
will prevail over the coastal waters through the end of the week
and into the coming weekend. Expect locally breezy winds near
coastal gaps and favored coastal jet locations during the
afternoon and evening hours. Mixed swell with a moderate northwest
swell and light southerly swell.

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.
