Synopsis Dry weather and seasonable temperatures are forecast
today and tomorrow. Cooler conditions along with a slight chance
of showers can be expected on Wednesday.

Discussion As of 3:00 pm pdt Monday... Widespread clouds
overnight for many spots with the marine layer still at 1500 feet
plus a moderate onshore flow. Similar to yesterday, most spots are
in the 50s and should see lows mostly in the upper 40s to the mid
50s by day break.

Today will be a near repeat of yesterday with clouds forecast to
slowly burn-off toward the coast by late in the morning. Yesterday
turned out to be a bit of a surprise in the east bay with a very
late transition to sunny skies. Models hint at the possibility
again today which could keep temps running a bit lower than
forecast. Outside of that, no issues anticipated with highs
expected to range from the 50s and 60s at the coast up to the 70s
and lower 80s inland. A few locations well inland could get into
the mid to upper 80s. Tonight will feature another round of patchy
fog and drizzle mainly near the coast.

Synoptically an upper level low will works it's way to the bc
coastline while an associated trough advances to the west coast.

Ahead of the main trough, a weak shortwave will move through on
Tuesday which will start to deepen the marine layer and provide a
degree or two of cooling. More substantial cooling (especially
inland) can be expected on Wednesday as the main trough moves
onshore. At the same time enough instability and associated
moisture could lead to a few showers late Tuesday into Wednesday,
although latest guidance has backed off a bit. Winds will also
pick up on Wednesday as the onshore flow increases. Westerly winds
of 10 to 20 mph with local gusts to 30 mph can be expected.

A weak ridge of high pressure will start to rebuild into our
region going to the end of the week. Highs will return back to
near normal levels.

Aviation 10:25 pm pdt Sunday for 06z tafs... Low clouds are
moving back in tonight with several terminals already reporting
ifr MVFR ceilings. Expect all terminals to see low clouds
as the night progresses and continue into Monday morning. Some
locations may see the clouds persist into the afternoon, or even
all day. West to northwest winds will become gusty by Monday
afternoon.

Vicinity of ksfo... Low clouds have pushed through the gap and have
brought overcast ifr ceilings to the most recent hourly
observation. Expect low clouds to persist through most of the
morning. Guidance suggests strong west winds on Monday afternoon
with gusts up to 25 or 30 kt.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Ifr ceilings overnight and through
Monday morning. Similar to Sunday, ksns has a better chance for
clearing in the afternoon whereas kmry may remain overcast through
the afternoon. Winds will increase Monday afternoon out of the
west at 10 to 20 kt.

Marine As of 10:09 pm pdt Sunday... Brisk northwest winds will
continue over the coastal waters tonight and into the memorial
day holiday as high pressure remains strong off the west coast.

The gusty winds will produce hazardous conditions with steeper
wind waves and fresh swell. Winds will decrease Tuesday night as
a weak frontal system moves through the coastal waters.

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.
