California – A quiet chill has settled over the Bay Area this morning as dense fog drapes city skylines and bridges in a silvery haze. Drivers can expect reduced visibility across the North Bay valleys, the Peninsula, and the East Bay’s lower elevations through late morning.
The National Weather Service in Monterey warns that patchy dense fog may form again late Friday and Saturday mornings, especially along I-80, Highway 101, and the I-280 corridor. Conditions may vary quickly — clear one block, pea-soup thick the next — so travelers should allow extra time and keep headlights on low beam.
Afternoon sunshine will break through, keeping highs near the low 60s across San Francisco and the mid-60s inland. Light winds from the northwest add a cool edge, but the weather remains pleasant for outdoor plans or returning post-holiday travelers. Nights will stay in the upper 40s, ideal for those putting up early holiday lights or enjoying late-autumn strolls.
Looking ahead, NOAA’s extended outlook points toward a colder and possibly wetter pattern for early December. A shift in the jet stream may draw in Pacific moisture, hinting at the Bay Area’s first real taste of winter rain.
