...Discussion from SFOFWFMTR...

A building marine layer is leading to cooler temperatures and higher
humidities across most of the region, barring the mountains of the
interior Central Coast where overnight humidity recoveries remain
poor. Breezy onshore winds are expected to develop each afternoon
and evening, with the strongest flow expected Thursday night into
Friday when gusts could reach 35-40 mph along the coast and at
higher terrain. Coastal drizzle is possible overnight into the
morning, but  accumulating rain is not expected.


...Discussion from SFOFWFEKA...

Hot, dry weather will continue to ease for the next few   days in
the interior, with a shallow marine layer mainly confined to  the
immediate coast. The marine layer will trend deeper through  late
week as low pressure rebuilds aloft helping push marine air  further
inland. This will bring a gradual cooling trend and  improved RH
recoveries, though daytime RH will generally still  remain no better
than about 25 percent through Friday. On Thursday and especially
Friday, fire danger will be elevated, especially  in Lake and
Mendocino Counties, with enhanced onshore winds  gusting up to
30 mph in the afternoon.
