Synopsis Low clouds linger in the bay area this morning. The
sun will return today to help confine cloud cover to the coast,
but temperatures will be slightly cooler Tuesday afternoon than
what it was yesterday. Clouds and patch fog are possible again
overnight and early tomorrow morning, which chances of patchy
drizzle near the coast.

Discussion As of 08:40 am pdt Tuesday... Steady onshore flow is
expected as the upper level trough moves slowly over northern
california toward the pacific northwest. Similar weather today
compared to yesterday. Mostly sunny skies with slightly cooler
temperatures inland and stratus clouds remaining along coastal
areas as the marine layer deepens.

As the trough axis passes over the bay area tonight and into
tomorrow morning, low clouds and patchy fog can be expected in the
bay area as well as extending into the north bay and southern
salinas valley. A chance of patchy drizzle can also be expected in
coastal san mateo county as well as along the coasts of southern
monterey bay. Mostly sunny skies tomorrow as temperatures remain
on the cool side for july in the bay area with no further updates
to the extended forecast.

Prev discussion As of 2:30 am pdt Tuesday... After a brief
disappearance the marine layer came back solidly along the coast.

Overnight satellite fog product shows decent cloud cover for much
of the coastline. A slight uptick in onshore flow will allow for
low clouds to move locally inland this morning.

Synoptically speaking the long wave pattern still shows an upper
level trough approaching the california coast(easily seen on
water vapor imagery). The trough will usher in a much cooler
airmass over the region dropping temperatures to below seasonal
levels today. Highs will be 60s at the coast and 80s to mid 90s
inland. Far interior locations will once again take a shot at 100
degrees, but less likely than previous days. The upper trough is
forecast to move over the region later today into Wednesday. The
marine layer is expected to deepen further with the passing
trough. Additionally, patchy drizzle has been added to the
forecast Tuesday night along the san mateo and monterey bay coast.

No changes to the forecast temperature wise Wednesday and heading
into the weekend. Temperatures are expected to moderate on
Wednesday, but then cool again Thursday Friday.

Temperatures begin to rebound slightly on Saturday, but more so on
Sunday as 500 mb heights begin to rise with building high
pressure. Despite the weekend warm up temperatures still remain
below normal for mid july. If you're tired of the cooler weather
longer range guidance has suggest a warm up during the extended
forecast. The 00z model suite is no different and shows 850 mb
temperatures exceeding 22-23 deg c by early next week returning
temperatures to normal or above normal. It should be noted that
the 6-10 and 8-14 day outlook from CPC shows above normal
temperatures for california.

Aviation As of 10:55 am pdt Tuesday... Shallow marine layer has
retreated from the inland sf bay but still intruding across
portions of the sf peninsula. An eddy in the monterey bay stratus
deck will keep ifr CIGS at kmry ksns kwvi for a couple of more
hours before clearing out. Main impact today will be another round
of breezy to gusty onshore winds across the coastally influenced
taf sites. Similar to yesterday, could see locally stronger gusts
mixing down through the san bruno gap into ksfo, with gusts up to
around 35kt possible 21z-04z today. For tonight, marine layer
should deepen and expand farther inland.

Vicinity of ksfo...VFR. West winds 20-22 kt gusting as high as
35 kt after 21z. Borderline ifr MVFR CIGS (at or around 1000 ft)
overnight.

Sfo bridge approach... Same as ksfo
monterey bay terminals... Ifr CIGS thru 20z thenVFR through
afternoon. Ifr CIGS return later this evening through Wednesday
morning. Breezy onshore winds with occasional gusts to around 20
kt.

Marine As of 10:51 am pdt Tuesday... Moderate to gusty northwest
winds across the waters from the golden gate gap northward
towards point arena through tomorrow. Locally gusty winds will
also develop along the big sur coast and portions of the western
santa cruz county coastline this afternoon. These winds will
generate steep fresh swell resulting in hazardous seas conditions
particularly for smaller vessels. Light long period southerly
swell will continue through at least mid week.

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.
