Synopsis Scattered showers and possibly an isolated
thunderstorm or two will continue through sunrise this morning
before a brief period of dry weather arrives by mid or late
morning. A second system is then expected to bring additional
rainfall to the area from thanksgiving evening through Friday, and
will bring gusty winds to parts of the area. Dry weather is
expected over the weekend before another chance of rain returns by
the middle part of next week.

Discussion As of 1:50 am pst Thursday... Kmux radar continues
to indicate post-frontal scattered showers passing from west to
east over much of the county warning area this early thanksgiving
morning. In fact, lightning was detected in one of the showers
around 11 pm pst along the monterey-san benito county line about 6
miles south of san juan bautista. Additionally, a thunderstorm
brought multiple strikes to southern napa county between napa and
yountville around 1:30 am pst. Rain amounts through the midnight
pst were impressive, particularly in the mountains where
orographically-enhanced precipitation was able to fall. For
example, the ben lomond mountain raws site in santa cruz county
reported 3.31 inches of rain and 3.24 inches at anderson peak in
monterey county.

The scattered rain showers and isolated thunderstorms are
expected to persist through sunrise across much of the area before
diminishing in coverage during the first half of thanksgiving day
as the upper level trough pushes inland. Eyes then turn to the
next system that will drop south during the afternoon and evening
hours, bringing a renewed opportunity for rain across much of the
bay area. In addition to the rain, moderate to locally strong
southerly winds will develop. The strongest winds are forecast to
occur across the sonoma and marin coasts, as well as the north bay
mountains where sustained southerly winds are forecast to reach
20 to 30 mph with gusts of 35 to 50 mph. Winds won't be as strong
in the north bay valleys, but nonetheless impactful at 15 to 25
mph with gusts of 30 to 35 mph. Consequently, a wind advisory has
been issued for the north bay valleys, mountains, and coast from 4
pm pst thanksgiving day through 4 pm pst Friday.

The second round of rain is expected to arrive to the north bay
sometime during thanksgiving afternoon, spreading south and
eastward during the late afternoon or evening hours, and
continuing into the overnight hours. As observed with Wednesday's
system, the higher elevations will likely see the most rainfall
out of this storm with the current forecast calling for an
additional 2-4 inches in the north bay mountains, 1.5-3 inches in
the santa cruz mountains, and 0.75-1.5 inches in the santa lucias.

For the population centers -- the north bay valleys can expect
about 1-2 inches of new rainfall, around 0.75-1.25 inches along
the san francisco peninsula, 0.5-1.25 inches in the east bay, and
generally less than 0.5 inches in the rain-shadowed santa clara
and salinas valleys.

After the Thursday-Friday system exits the area, ridging is then
forecast to return to california for the weekend with multiple
days of dry weather expected. Forecast guidance has been rather
consistent over the past few days with bringing in another system
associated with a eastern pacific longwave trough by around
Tuesday or Wednesday, and another around Thursday. Beyond
Thursday confidence begins to decrease rapidly as model solutions
begin to diverge. With all that said, though, unsettled weather is
expected to continue across the region into the final week of
november.

Aviation As of 09:31 pm pst Wednesday... Bulk of the precip has
ended and transitioned to hit or miss shower activity. CIGS and
categories are bouncing up and down based on shower activity.

Will keep a vcsh scenario through tomorrow morning before some
gradual clearing. Brief break in the afternoon before another
round of rain from the north.

Overall conf - medium
vicinity of ksfo... Passing showers continue to cause problems with
cigs and visuals to the south. Expect this trend to linger for a
little longer with improvement later tonight. Showers return late
tomorrow with increasing southerly winds.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR conditions that may briefly drop to
MVFR with passing showers tonight and tomorrow.

Marine As of 09:25 pm pst Wednesday... Scattered showers, gusty
winds and possibly a thunderstorm through tonight as a storm
system exits to the east. Another storm system will bring gusty
southerly winds to the northern waters between Thursday and
Friday afternoons. Gale force gusts are also forecast for north of
the bay bridge through the west delta on Friday. Mixed swell,
predominately moderate northwest swell with a light southerly
swell.

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.
