Mixes out marine layer except for a patch near Half Moon Bay and Santa Cruz.  • The Sunday Night Peak: An even stronger, deeper pulse of dry offshore downslope winds is forecast to slam the Bay Area and North Bay ridges from Sunday night into Monday morning. While wind speeds will stay just below official Wind Advisory criteria, these nocturnal winds will cause severe humidity drops, keeping mountain fire behavior aggressively active overnight. . • Temps inland up to and over 100 degrees through Monday!
