California, USA – Sheets of steady rain sweep across San Francisco before sunrise, streaking glass towers and pooling on Market Street as wind gusts nudge umbrellas sideways. Wet pavement reflects blurred headlights, signaling a disruptive start to the week just as Thanksgiving travel begins ramping up across the Bay Area.
According to the National Weather Service in San Francisco/Monterey, a robust Pacific system delivers widespread showers today, including heavier bursts by midmorning. Drivers along I-80, Highway 101, and the Bay Bridge should plan for slower travel, slick lanes, and sudden visibility drops. Residents heading to early commutes or airport runs should allow significant buffer time and secure rain gear.
According to meteorologists, today’s winds strengthen over the hills, and isolated thunderstorms may develop during the late afternoon. While hail looks unlikely, brief downpours could trigger minor street flooding in low-lying pockets of SoMa, the Mission, and Civic Center. Conditions ease tonight as showers weaken, but wet roads remain a concern for evening events.
According to Caltrans, crews will monitor high-traffic choke points, especially along I-80 toward Oakland and the 101 corridor through downtown. Travelers beginning early Thanksgiving trips should check updates twice daily and prepare for delays at regional airports if winds increase.
Tuesday offers a welcome break as skies clear, winds calm, and temperatures climb into the low 60s. Sunshine provides ideal conditions for errands, shopping runs, and early holiday preparations. Models hint at a Winter Tease returning Wednesday, bringing another surge of rain that may again slow travel during the afternoon push, though temperatures stay comfortably above any frost risk.
A brighter stretch returns for the weekend, giving the region a gentle window for decorating, outdoor plans, or short holiday getaways before another system forms late Sunday.
