Synopsis Pronounced onshore flow today will lead to cooler
conditions today and Tuesday compared to Sunday. Modest warming
is expected during the second half of the week, however highs will
fall well short of the recent heatwave.

Discussion As of 3:00 am pdt Monday... Clouds mostly cleared
from our CWA later yesterday but satellite shows that they have
returned to san mateo county northward. Clouds are continuing to
stream to the southeast and will be down into monterey county
by sunrise. Patchy fog and drizzle can be expected into the
morning.

Synoptically the ridge of high pressure that had been overhead is
now well to the east while the onshore flow combined with a
moderate marine layer will lead to cooler conditions compared to
yesterday especially for spots away from the coast. Highs will
range from 60s near the water with mostly 70s to mid 80s inland.

In general, temperatures will be 3 to 6 degrees cooler compared to
Sunday. Similar conditions can be expected tonight into Tuesday.

By Wednesday a ridge of high pressure will rebuild into the
pacific and toward our region. This will lead to slight warming
into Thursday. Inland highs will return to the upper 70s to lower
90s with coastal spots in the 60s to the mid 70s. Those
temperatures will hold into early next week and possibly into the
following week.

Aviation As of 04:10 am pdt Monday... A non-typical marine
layer developed overnight and is impacting most terminals, but not
quiet yet at kmry ksns. CIGS are mostly above 1k ft. Will have
mid to later morning burn off. Conf is rather low on stratus
impacting kmry ksns.VFR this afternoon. CIGS return this
evening overnight.

Vicinity of ksfo... MVFR CIGS around sfo this morning. Based on
timing of yesterday and model guidance today will keep the 18z
clearing. Conf is low to moderate.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR as of now, but will keep stratus
tracking toward kmry with a toa around 13z. If CIGS develop will
keep CIGS for a brief time through 16-17z.VFR this afternoon.

Cigs return tonight.

Marine As of 04:09 am pdt Monday... Light to moderate northerly
winds will persist over the coastal waters as high pressure
remains over the eastern pacific. Locally stronger winds will be
possible along the immediate coast and in san francisco bay. A
dominant southerly swell will persist into Wednesday morning.

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.
