Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Northwest winds will increase this afternoon through at least Tuesday as a strong surface pressure gradient builds across the region. At the same time, a building northwest swell will pass through the waters. Typical gusty spring time northwest winds will continue at least through midweek and likely through Friday as the next weather system will likely increase the surface pressure gradient once again.

Synopsis Partly cloudy skies are forecast today along with
brisk northwest winds during the afternoon and evening. High
pressure will build over california through midweek, resulting in
dry weather and a warming trend through Wednesday. Slightly cooler
conditions are expected on Thursday as a weather system moves
into eastern california. That weather system will bring only a
slight chance of showers to the northern and eastern portions of
our area, and also result in blustery conditions near the coast
and in the hills by late Thursday. High pressure will redevelop
late in the week and result in warmer weather once again by the
weekend.

Discussion As of 2:45 am pdt Monday... The weak frontal system
that brought light rain to much of our region Sunday afternoon and
evening has moved off to our east and south early this morning.

Radar still shows isolated light showers over our area, but all
shower activity is expected to end by daybreak as drier air
continues to move in from the northwest. That drier airmass is
already resulting in clearing in the north bay and this clearing
trend is expected to continue from north to south through this
morning. By afternoon, expect mostly sunny to partly cloudy skies
in all areas.

Surface high pressure will begin to build off the northern
california coast today and the resulting tightening pressure
gradients will generate brisk northwest winds along the coast
this afternoon. Local gusts up to 35 mph are possible in the
windier coastal locations from late afternoon through early
evening.

An upper level ridge is forecast to build over california during
the next few days, resulting in dry weather and a warming trend
through Wednesday. By Wednesday, high temperatures will be mostly
in the upper 60s and 70s, with a few lower 80s possible in
monterey and san benito counties.

Daytime temperatures on Thursday will cool by 5 to 10 degrees as
an inside slider type system drops inland to our east. The gfs
keeps all precipitation with this system to our north and east,
but the ECMWF tracks the system a bit farther to the west and
clips the northern and eastern fringes of our area with light
shower activity late Wednesday night and Thursday morning. Either
solution will result in blustery conditions in the hills and near
the coast by Thursday afternoon when locally strong northwest
winds develop. Northerly winds will ease near the coast by Friday,
but remain locally strong and gusty in the hills into Friday
night.

Upper level ridging is forecast to redevelop over california just
in time for the weekend, and current model projections indicate
dry and seasonably warm weather on both Saturday and Sunday.

Aviation As of 4:55 am pdt Monday for 12z tafs. Winds have
switched to the northwest overnight with a weak frontal passage.

ExpectVFR conditions to prevail after 16z. There are a few low
clouds around ksfo and kmry as of 11z, but not expecting there to
be significant impacts as the boundary layer continues to dry
through the day. West to northwest winds can be expected this
afternoon with possible gusts exceeding 25 kts in the afternoon.

Vicinity of ksfo... MVFR conditions early this morning with a few
low cloud decks. Expect ceilings to improve by 16z as drier air
continues to move in. West to northwest winds will become gusty
this afternoon in excess of 20 to 25 kts.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... A few low clouds continue to impact kmry
this morning with ceilings around 3000 ft. ExpectVFR conditions
by mid-morning with gusty west to northwest winds this afternoon,
notably at ksns.

Marine As of 04:47 am pdt Monday... Northwest winds will
increase this afternoon through at least Tuesday as a strong
surface pressure gradient builds across the region. At the same
time, a building northwest swell will pass through the waters.

Typical gusty spring time northwest winds will continue at least
through midweek and likely through Friday as the next weather
system will likely increase the surface pressure gradient once
again.

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.
