Synopsis The cooling trend continues today with clear skies
inland with a deep marine layer and stratus clouds along the
coastline. These conditions should continue on Sunday as well. Dry
and seasonable temperatures are expected Monday and Tuesday before
the next warming trend begins midweek.
Discussion As of 01:33 pm pdt Saturday... Another day to show
off the cooling trend that is currently under way for the bay
area. At the time of writing this afd napa is 12 degrees cooler
than this time yesterday, concord and san jose are 13 degrees
cooler, and livermore is 18 degrees cooler. These cooler temps are
being driven by an upper level trough axis sitting right over the
bay area. The fort ord profiler has shown the marine layer has
deepened to 2500 feet by 9am this morning while onshore flow
persists along the coast. Clear skies can be found for inland
locations, but stratus clouds linger just offshore. There is a
small chance for patchy areas along the san mateo, santa cruz, and
big sur coastlines to have light drizzle overnight and in the
early morning hours Sunday. But most drizzle chances should be
done by mid morning. Tomorrow, the stratus will continue to linger
near the coastline, while inland areas should be mostly clear
once again. The cooling trend continues tomorrow, but with less
magnitude than yesterday and today.
The low in canada that is directing the trough moves eastward Sunday
evening, as high pressure begins to build over texas. The growing
high pressure will rotate the trough from a positive tilt to a
negative tilt, but with near consistent dam heights it will not
impact the conditions at the surface. This will allow for dry,
seasonal conditions for the early work week. As a strong low takes
shape in the north pacific, the high pressure continues to build
in the southern plains and slowly shifts toward the desert
southwest by midweek, leading to a warming trend for the bay area
expected to last until the end of the work week.
Aviation As of 10:45 am pdt Saturday...VFR conditions have
returned across much of the bay area with lingering MVFR ifr
ceilings holding on around the monterey bay terminals. Should see
improving conditions region-wide as low clouds dissipate and|
scatter through the remainder of the morning. Onshore winds will
increase a bit and become locally gusty this afternoon and
evening. Latest thinking is that low clouds will make an early
return late this evening as the marine layer continues to deepen.
Timing of clearing on Sunday remains a bit more tricky as cold air
advection arriving from the north should help to mix out the
marine inversion. However, look for MVFR ifr ceilings to impact
most terminals overnight tonight through early Sunday morning.
Vicinity of ksfo...VFR. Onshore winds will increase and become
locally gusty through the afternoon. Low clouds potentially make
an early return late this evening and will likely linger into
Sfo bridge approach... Similar to ksfo.
Monterey bay terminals... MVFR ifr conditions linger this morning
given a decent onshore and a moist boundary layer. Should see
these clouds scatter out by early afternoon giving way toVFR
conditions. Modest onshore winds will also persist this afternoon
and into the early evening hours. MVFR ifr conditions return late
this evening and will likely persist into Sunday morning.
Marine As of 4:41 am pdt Saturday... Moderate to gusty
northwesterly winds will continue over the northern and outer
waters into Sunday as high pressure remains over the eastern
pacific. This high pressure will begin to weaken into Sunday
before a strong low pressure center develops and approaches
british columbia early next week. The persistent fetch produced by
these systems will generate fresh short period swell that will
propagate into the california coastal waters. This short period
swell in combination with gusty winds will generate hazardous seas
conditions, particularly for smaller vessels.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
