San Francisco, Calif. – Dense fog blanketed the Bay Area early Wednesday, reducing visibility to a quarter mile or less on major roads.

Once the fog clears, skies turn sunny with highs reaching near 78 degrees by afternoon. Winds shift southwest at 10 mph, calming after sunset.
Thursday brings a slight chance of thunderstorms after 5 p.m., with clouds building across the Bay Area. Winds could gust up to 18 mph, and rainfall may reach a tenth of an inch.
