837 pm pdt Sun jul 27 2014

Synopsis A combination of monsoon and subtropical moisture will
continue to move across the forecast area into Tuesday. This will
result in periods of mid and high level clouds. There is also a
slight chance of isolated light showers or thunderstorms during
that time. Temperatures are forecast to remain near normal or
slightly above normal through the week.

Discussion As of 8:37 pm pdt Sunday... Showers and thunderstorms
have tapered off for the evening as low clouds begin to make
their way to the coast. It was another warm day today with
temperatures running 5 to 10 degrees above normal at many
locations. San francisco international airport reached a high of
77 with normal temperature of 72... Sonoma county airport reached
92 with a normal temperature of 83 degrees and salinas airport
reached a high of 76 with a normal high of 71 degrees. Several
lightning strikes were observed around the area today due to the
monsoon/subtropical moisture and elevated instability. Roughly 72
lightning strikes were observed offshore with 3 strikes occurring
over land... 1 near hollister... 1 near gilroy and 1 in carmel
valley.

The latest satellite water vapour image continues to show a
combination of monsoon and subtropical moisture pushing into
southern california. The 1200z ECMWF and 1800z gfs40 have
initialized well with the current synoptic pattern and both
continue to advect the previously mentioned moisture into the
forecast area through Tuesday. Upper air analysis with the 1800z
nam12 shows elevated instability over the forecast area modified
totals around 32 hovering along the coast through Tuesday. The
combination of elevated instability and moisture will support
showers and isolated thunderstorms in the forecast for Monday and
Tuesday.

By Wednesday the subtropical link moves to the west and the monsoon
moisture slides to the east leaving clearing skies over the
forecast area for the remainder of the forecast period. Onshore
winds and morning low clouds will help to maintain near normal
temperatures for the remainder of the week as well.

Aviation As of 4:45 pm pdt Sunday... Radar and satellite image
shows a few showers off the san mateo coast over the waters. These
showers are decreasing but cannot rule out the possibility of
sprinkles at sfo through 03z. Stratus continues near the coast but
will stay out of the sfo bay area until after the airport evening
rush. Low confidence on whether the stratus makes it into the sfo
bay area later tonight as the onshore flow is weak and marine layer
is shallow.

Vicinity of ksfo...VFR through the airport evening rush. West
winds gusting to 25 kt through 04z. Stratus may return after 10z
but confidence is low as it may stay out all night.

Ksfo bridge approach... Similar to ksfo.

Monterey bay area terminals... A patch of stratus has developed
around point pinos in the past hour. Ifr spreading into mry after
03z and sns after 04z.

Marine As of 5:00 pm pdt Sunday... A few showers continue over
the coastal waters mainly west of the san mateo and santa cruz
county coast. Lightning was detected as recently as 21z but none
since. Thunderstorm chances will persist through Tuesday over the
coastal waters as subtropical moisture continues to stream into
the area. Otherwise light north to northwest winds and seas will
continue into early next week.

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.
