.DISCUSSION...Gusty south-southwest and upslope winds will
decrease overnight tonight, becoming light and downvalley by
early tomorrow morning. RH recoveries are once again expected to
be good. Expect another warm and somewhat gusty day again
tomorrow, with a return of south and southwesterly upvalley
breezes. Wind gusts are expected to be slightly lower than they
were today, and more westerly along the ridges.

Overnight tomorrow offshore winds are expected to develop, which
will result in gusty northeast winds and moderate to poor
recoveries at high elevations, likely in exposed areas above 2500
feet. Winds near the valley floor are expected to be mostly light
and northerly/downvalley with good RH recoveries.

Chances for thunderstorms, some potentially dry, increase Sunday
afternoon and evening.
