California – Umbrellas dot sidewalks and tires hiss on wet pavement as light rain spreads across San Francisco this morning, slowing traffic and reducing visibility through the early commute.

According to the National Weather Service, rain and isolated thunderstorms continue through late morning, with precipitation chances near 60% and brief downpours possible before conditions improve this afternoon . Rainfall totals stay light, generally under 0.10 inch, but bursts could briefly impact travel.

Across San Francisco, Oakland, and Daly City, drivers along US-101, I-80, and I-280 should expect slick roads and longer braking distances through midday. Visibility may drop quickly under heavier showers. If you’re heading across the Bay Bridge, allow extra time and keep headlights on.

Conditions shift quickly after lunchtime. Skies begin clearing, and drier air moves in by mid-afternoon. This sets up a noticeably calmer pattern heading into Thursday, when sunshine returns and highs climb near 68°F. It’s a quick transition from damp to mild.

Looking ahead, Friday stays partly sunny with highs in the mid-60s, while Saturday trends cooler near 64°F with increasing clouds. By Sunday, temperatures rebound slightly into the mid-60s again. No major storm systems are expected locally, though a broader western system continues to bring mountain snow inland.

Temperatures remain in the low 50s at night. While freezing isn’t a concern here, slick roads can still develop during early morning moisture—stay alert on shaded streets.
