Synopsis High pressure will remain over the west through most
of next week resulting in continued dry conditions. Daytime highs
will be warmer than normal and nights will be seasonably cool.

Discussion As of 9:00 pm pst Sunday... Upper level high is over
northern nevada this evening. Strong 1045 mb surface high
pressure over the great basin continues to dominate bringing dry
offshore flow to the area. This brought record high temperatures
around the south bay and coastal areas today with records set at
san jose... Salinas... And half moon bay and tied at monterey.

Nights will continue to be cool especially in the valleys where
patchy fog may form in wind-protected areas.

The upper high will get pushed slightly southeast as a weak upper
level shortwave approaches the british columbia coast but will
keep its hold over our district through much of the coming week.

The surface high will slowly weaken over the next couple of days
but pressure gradients will still be offshore until Tuesday when
pressures between the coastal waters and inland areas equalize. By
then we should start to get a light seabreeze going. Daytime
temperatures are not going to change much this week with the
upper high still around. But nighttime temperatures will start to
moderate and there should be a little more humidity after
Tuesday.

Medium range models are indicating the ridge will flatten late in
the week as a weather system moves into the pacific northwest but
rain will remain well north of the district. In fact by next
weekend high pressure rebuilds off the coast and surface high
pressure builds into oregon bringing another round of offshore
flow.

Beyond that the 12z run of the ECMWF seems to be coming into
better agreement with the GFS in showing the ridge amplifying over
alaska by the 20th and a trough moving in to take its place over
the west coast with maybe even some precipitation for northern
california.

Aviation As of 3:37 pm pst Sunday for 00z tafs. No major
updates from previous TAF package. Strong high pressure will
continue over the western conus, resulting inVFR conditions
through the forecast period. Kept fog in the TAF at ksts late
tonight, into Monday morning. Generally light winds expected
overnight across the district.

High confidence.

Vicinity of ksfo...VFR. Light offshore winds expected through the
forecast period.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR. Generally light winds overnight,
though breezy east southeast winds are expected at ksns overnight
tonight and Monday morning.

Marine As of 3:00 pm pst Sunday... Locally breezy conditions
will continue overnight along coastal gaps as high pressure
remains parked over the west coast. A longer period west to
northwest swell will arrive later tonight and will continue into
Monday.

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.
