California – Fog clings to the coastline early, headlights glowing through mist as damp air signals a bigger shift already underway.
That patchy fog lingers into the morning commute, briefly lowering visibility near the Golden Gate and along Highway 101. Roads may feel slick in spots even before steady rain arrives.
According to the National Weather Service, rain chances increase quickly through the day, with showers developing by late morning and intensifying into the evening. A 50% chance of rain expands into a widespread 90% likelihood by Friday, with embedded thunderstorms possible.
By Friday evening, expect steady rain across San Francisco, Oakland, and surrounding Bay Area communities. Wet pavement and slower travel are likely during peak hours. Plan extra time if heading across bridges or along I-280.
Saturday brings the most significant impact. Rain becomes widespread and persistent, with a 100% chance of precipitation. Periods of moderate rainfall could total up to a quarter inch or more, especially during heavier bursts.
Keep rain gear handy and avoid unnecessary travel during peak downpours.
Saturday night into Sunday stays unsettled. Rain continues with a 90% chance Saturday night and near 90% again Sunday. Temperatures hold in the low 60s during the day and drop into the upper 40s at night, adding a chilly edge.
Localized ponding on roadways is possible, especially in low-lying urban areas.
By early next week, skies begin to clear. Sunshine returns Monday with drier conditions and highs rebounding into the mid-60s.
