...Red Flag Warning North and East Bay hills as well as East Bay
interior valleys 11 pm Friday through 6 am Monday for offshore
winds and lowering humidity...

.A moderate early season offshore wind event will develop this
weekend. This will occur as fuels are near record dry levels
after a very dry winter. The initial burst of dry offshore winds
will reach the Napa county hills around 11 pm Friday night and
then spread across the East Bay overnight into early Saturday.
These winds will usher in much drier air along with wind gusts in
excess of 50 mph above 2000 feet. On Saturday breezy north winds
will continue as temperatures warm well into the 80s with
humidity values lowering into the teens and single digits. This
pattern will help to rapidly dry out the fine fuels through the
weekend. There may be some moderate humidity recovery Saturday
night but warm and dry weather persists Sunday with continued dry
northerly winds and warm temperatures that will allow for rapid
fire spread on any new ignitions, especially in the grass and dry
brush.
