...Discussion from Monterey...

The fire weather threat will remain subdued  due to widespread
wetting rainfall anticipated over the next 24  hours across most of
the Bay Area and Central Coast. Overnight  humidity recovery will be
excellent with values above 80%.  Additional rainfall amounts will
average between three quarters of an inch to near two inches.
Southerly winds will gusts between 30 and 40 mph winds are
anticipated ahead of a cold frontal  boundary. This front will usher
in an additional round of rainfall through the day on Friday. Winds
will become more westerly late  Friday and into the day on Saturday.

Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.

...EXTREME DRYING OVER THE MOUNTAINS AND INTERIOR THROUGH FRIDAY WITH
LOCALLY GUSTY WINDS RESULTING IN ELEVATED FIRE WEATHER CONDITIONS...

...WIDESPREAD WETTING RAINS LIKELY WITH SIGNIFICANT COOLING AND
MOISTENING FRIDAY NIGHT THROUGH AT LEAST WEDNESDAY...

High pressure aloft will peak through Friday. An extremely dry air
mass will drop down into southwest California focused over the
mountains and many valleys. Minimum humidities will lower to 3 to
10 percent. Very poor to non-existent overnight recoveries will be
felt over many mountain and foothill locations. Meanwhile, southeast
to southwest wind gusts of 20 to 30 mph will be common over the
mountains and foothills.  Due to the very dry air, elevated fire
weather conditions are expected  with isolated brief critical
conditions over the windier mountains.

A significant pattern change will commence Friday Night and last
through next week. Confidence is high in widespread rain over the
region, and that impacts will be minimal through at least Sunday.
Confidence on the details for Monday through Wednesday however
remains low. The most likely outcome is for widespread light to
moderate rain with impacts focused on the roads. There remains a
non-zero but low threat however for heavier rain with flooding
concerns. The chance for rain over Thanksgiving Thursday and Friday
is lowering.
