Sacramento, CA – Thick fog hangs low across the valley this morning, blurring headlights and swallowing familiar roads. Visibility drops suddenly, especially near rivers, farmland, and open stretches of highway, creating hazardous driving conditions as the day begins.
According to the National Weather Service in Sacramento, a Dense Fog Advisory remains in effect until 11 a.m. Visibility may fall to one-quarter mile or less across the Sacramento Valley, Delta, and Carquinez Strait. The advisory includes Sacramento, West Sacramento, Davis, Woodland, Elk Grove, and surrounding communities.
Drivers should expect rapidly changing visibility on major routes including I-5, I-80, Highway 99, and Highway 50. Low speeds, longer stopping distances, and sudden slowdowns are likely during the morning commute. Use low-beam headlights, allow extra following distance, and avoid sudden lane changes.
Fog lingers into late morning before slowly lifting. Skies stay mostly cloudy through the afternoon, with highs near 44 degrees, keeping the air cool and damp. Patchy fog may redevelop again tonight and early Monday, continuing a familiar December pattern across the Central Valley.
By Monday afternoon, clouds increase as a weak system approaches. Rain chances rise late Monday into Tuesday, with scattered showers possible by Tuesday afternoon and evening. While snow is not expected in the valley, cooler nighttime temperatures combined with wet roads could lead to slick conditions during early morning hours.
This is the week before Christmas, and travel volume increases daily. Morning fog and later-week rain could create delays at the worst times. Plan ahead and check road conditions before leaving home.
Five-Day Outlook for Sacramento:
- Today: Dense fog early, mostly cloudy, high near 44
- Monday: Morning fog, mostly cloudy, high near 50
- Tuesday: Patchy fog, chance of showers late, high near 56
- Wednesday: Showers likely, high near 61
- Thursday: Slight chance of showers, high near 58
