Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Building high pressure over the eastern pacific will result in the strongest pressure gradients setting up near cape mendocino. This will keep the strongest winds over the northern and outer waters while much lighter winds and wind waves will persist across the near shore waters south of pt reyes through Friday.

Synopsis Warmer temperatures are forecast for today and Tuesday
as high pressure strengthens over california, and onshore flow
weakens. However, warming at coastal areas will be limited due to
persistent onshore winds. Seasonable temperatures, along with
areas of night and morning low clouds, are forecast through the
end of the week and into next weekend.

Discussion As of 01:35 pm pdt Monday... Slightly compressed
marine layer, building high pressure and increasing northerly flow
all helped for an earlier burn off of the stratus deck this
morning. Even coastal section are seeing more sunshine today with
a more disorganized cloud deck hugging the coast today. The
increased sunshine and warmer airmass also translated to warmer
temperatures today. The latest 24 hour trend has many locations
running a few degrees warmer than yesterday and interior locations
as much as 10 degrees warmer.

No major changes to the overall forecast. High pressure will
continue to build over the bay area keep a warming trend through
Tuesday then moderating temperatures Wednesday. Night and morning
low clouds and even patchy drizzle will continue. The coverage
will clouds will decrease however with the building 500mb heights
and increasing n-s gradient. Scaled back on clouds tonight across
the north bay valleys and inside sf bay. San mateo coast southward
into the salinas valley will see good coverage. Not only will
there be warm temperatures during the day overnight lows in the
hills will remain mild. Given the airmass will still be in the mid
20c range at 850 mb overnight lows in the 60s and 70s will be easy
to get in the hills.

By Wednesday and more so on Thursday a trough in the gulf of
alaska will pivot through the pacnw. This passing trough to the
north will flatten the overhead ridge bringing much cooler weather
to the bay area. In fact, temperatures on Thursday will actually
be at or below normal for many locations. A reverse in the
temperature trend occurs again Friday and into the weekend the
trough exits into the great basin. Not a real big warm up just
returning closer to normal.

Aviation As of 10:52 am pdt Monday... For 18z tafs. Stratus has
rapidly cleared from bay area terminals as northerly gradient is
strengthening and inversions are compressing as high pressure
builds. This is pushing last vestiges of stratus to the monterey
bay region where clearing will be slow or non-existent for kmry.

ExpectingVFR through this evening for bay area terminals.

Developing pattern suggests that stratus will have a harder time
pushing inland tonight so livermore and perhaps ksts will stay
stratus free should northerly gradients persist. Have trended back
on cloud coverage for Tuesday morning given expected forecast of
stronger northerly gradients and shallow marine layer.

Vicinity of ksfo...VFR this afternoon and evening. Expect sct
clouds to hold off until early Tuesday morning.

Sfo bridge approach... Approach will be clear through tonight.

Impacts to approach should be short lived Tuesday morning with
light offshore flow aloft and shallow marine layer.

Monterey bay terminals... Clearing for ksns but clouds may linger
for kmry for much of the day. TAF will show just tempo scattered
through this afternoon. Shallow cloud layer will move back in by
early evening and linger overnight, likely through at least 18z
Tuesday for kmry.

Marine As of 10:44 am pdt Monday... Building high pressure over
the eastern pacific will result in the strongest pressure
gradients setting up near CAPE mendocino. This will keep the
strongest winds over the northern and outer waters while much
lighter winds and wind waves will persist across the near shore
waters south of pt reyes through Friday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
