Synopsis Seasonably warm conditions during the day with patchy
coastal clouds at night will continue the rest of the week and
into the weekend. The forecast remains dry through the middle of
next week. Cooler weather returns next week.

Discussion As of 02:50 am pdt Wednesday... Offshore flow
continues to weaken (sfo-wmc gradient down another 4mb) as
onshore flow increase. Overnight GOES east satellite fog product
shows a summer type set up with coastal low clouds pushing locally
inland. Automated stations puts cloud heights at only a few
hundred feet with patchy dense fog. Therefore, added some patchy
dense fog around monterey bay, san mateo coast and santa rosa
vicinity. Expect clearing back to the coast by mid-morning with
sunny skies this afternoon. Similar to yesterday morning, it will
be chilly with a few interior pockets dipping into the upper 30s.

The longwave pattern aloft will gradually evolve over the next few
days and moreso next week. Currently the upper low over northern
arizona will continue to drift to the NE as ridging builds across
the pac nw. By Friday, high pressure aloft becomes established
over or as low pressure develops over socal as a weak rex block
into the weekend. So what does this mean for the bay area? Mild
daytime temperatures with cool overnight temperatures. Night and
morning low clouds will be possible along the coast and locally
inland. Conf is low on extent of clouds as some weak offshore flow
remains. Above the cloud deck, dry conditions will remain over the
hills keeping fire weather concerns heightened.

The 00z model suite continues to advertise another pattern shift
next week. The blocking pattern is short lived as an upper level
trough moves into the west coast. Confidence on precip chances
continues to remain low, but one thing that is more certain is
widespread cooling. Current forecast will bring temperatures down
by Monday with increasing clouds and a low chance for precip
across the north bay.

Aviation As of 10:00 pm pdt Tuesday... Satellite image shows
areas of stratus over the waters. Stratus is filling mry bay and
should spread into mry and sns. Latest NAM guidance shows cigs
into sfo and oak early morning so have added that into the tafs.

Vicinity of ksfo... Occasional MVFR CIGS between 12z and 16z.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Ifr CIGS after 07z clearing after 17z.

Marine As of 09:33 pm pdt Tuesday... High pressure over the
eastern pacific coupled with a thermal trough along the coast will
maintain light northwest winds through Sunday. A long period
northwest swell will arrive on Wednesday bringing an increased
risk of rip currents and sneaker waves. Swell period will decrease
Wednesday night and Thursday.

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.
