Synopsis Very warm to hot conditions will persist inland
through the weekend. A persistent but shallow marine layer and
light onshore flow will maintain mild conditions at the coast.

Cooling is then forecast during the early part of next week.

Discussion As of 8:45 am pdt Saturday... A 596dm 500mb high
pressure ridge remains over the region this morning, contributing
to a compressed marine layer near the coast and mostly clear skies
elsewhere. Very little day to day change is expected for today
versus yesterday. That said, the weather pattern is forecast to
shift soon. An approaching trough will settle into oregon norcal
by late tonight through early next week, which is expected to
flatten and thus weaken the ridge currently in place. This will
ease the suppression of the marine layer, allowing it to deepen,
and set temperatures on a slight cooling trend. Temperatures will
be their lowest on Tuesday, with afternoon temperatures 3 to 8
degrees cooler than normal nearly everywhere except the most
extreme inland locations, which may continue to run near to
slightly above normal. This translates to mid to upper 60s along
the coast and sf bay shoreline, with 70s to low 80s just inland,
to mid 80s to low 90s for extreme inland locations.

Previous discussion As of 3:19 am pdt Saturday... The marine
layer has compressed to around 1000 feet, per the latest fort ord
profiler output, and satellite imagery confirms with only limited
inland extent to the coastal stratus so far. The most appears to
be into the salinas valley, with monterey and salinas airports
both indicating visibility restrictions due to fog. The san
francisco bay area appears to be less impacted with no ceilings
currently being reported at bay area airports. With a high
pressure ridge still in place over the state, expect warmer
temperatures across the district but mostly across inland areas.

Highs today are forecast to range from 60s to mid 70s near the
coast, and 80s and 90s inland. Warmest inland spots could easily
exceed the century mark.

Warm hot temperatures will persist through Sunday as the ridge
will remain in effect. Cooler temperatures are anticipated by
early next week, though, as an upper level trough displaces the
ridge over the west. Inland temperatures could be as many as 10
degrees cooler compared to weekend temperatures, however, coastal
temps should see less change. Medium range models keep a baggy
trough over the west through the remainder of the forecast period
maintaining the moderate temps.

Aviation As of 4:45 am pdt Saturday... Marine layer has
compressed as upper level ridge has built over the area. Stratus
extends along the coast but has made little inland progress.

Local stratus is possible at oak butVFR is expected for the sfo
approach.

Vicinity of ksfo...VFR. West winds 16-18 kt after 21z.

Sfo bridge approach...VFR.

Monterey bay terminals... Ifr CIGS with local vsbys down to 1 2
mile through 15z. BecomingVFR after 17z at sns and 18z at mry.

Marine As of 08:23 am pdt Saturday... High pressure persists
over the eastern pacific with a thermal trough over inland
california. Northwesterly winds will remain generally light
through the week aside from locally gusty winds in the northern
outer waters through Tuesday as the trough over california
strengthens. Light to moderate mixed swell will continue along
with a longer period 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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
