Synopsis Smoke and haze will continue to produce poor air
quality over much of the san francisco bay through the weekend.

Dry and mild conditions are also likely to persist through early
next week. A more significant pattern change appears likely
during the latter half of next week with the potential for
widespread rainfall.

Discussion As of 1:58 pm pst Thursday... Smoke from the camp
fire continues to be the main impact across the district, but
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 a weak
windflow pattern persists.

Minor day-to-day changes are expected through the upcoming
weekend with daytime temperatures in 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
will also 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. Latest runs of the medium range models
continue to indicate a more likely chance of measurable rain for
the area. The 12z ECMWF maintains its trend of bringing a weak
frontal system across much of the area on Wednesday, followed by
a stronger front on Friday, with residual showers extending into
Saturday. The 12z GFS holds off the first system until
thanksgiving, followed by another system on Friday. The rainfall,
along with stronger onshore flow, is expected to help clear out
the smoke from the area.

Aviation As of 03:31 pm pst Thursday... For 00z tafs. Widespread
smoke continues to impact the region, particularly around the sf
bay area terminals. Most sites are now at MVFR ifr conditions due
to reduced vis. Do not expect much if any improvement in smoke
through the period. MVFR ifr vis will continue through the period
with occasional MVFR cigs. Slant range vis issues will also
persist and impact arrivals. Smoke impacts may remain an issue
until the next storm system, which right now looks like late next
week. Generally light winds through the period.

Vicinity of ksfo... MVFR ifr vis with MVFR CIGS due to wildfire
smoke. Winds will remain light.

Sfo bridge approach... Similar to terminal.

Monterey bay terminals... Conditions have worsened to MVFR with
kmry currently at 4 mile vis. Latest hrrr smoke forecast does not
suggest much improvement. Expect MVFR vis through much of the
period with occasions ofVFR. Onshore winds will continue into
the early evening before turning southerly.

Marine As of 03:01 pm 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.

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.
