California – Headlights glow through thick gray air across the Sacramento Valley this morning as dense fog blankets neighborhoods, freeways, and river crossings. Moist pavement shines under streetlights, and visibility drops quickly in low-lying areas, especially near the Sacramento and American rivers.
According to the National Weather Service in Sacramento, widespread dense fog developed before sunrise and lingers through the morning hours, with visibility dropping to a quarter mile or less at times. Temperatures sit in the mid-40s early, allowing fog to cling stubbornly before partial clearing later in the day.
Across Sacramento, Elk Grove, Davis, and Roseville, drivers should expect slow travel during the morning commute. I-5, Highway 99, and I-80 are especially vulnerable to sudden visibility drops. Calm winds allow fog to redevelop again tonight, repeating the pattern into Friday morning.
By Friday, clouds increase with highs in the mid-50s. Fog remains a concern early, then gradually thins as daylight strengthens. Saturday turns brighter and warmer, with sunshine pushing highs near 60. Clear skies Saturday night allow temperatures to fall into the upper 30s, raising the risk of slick spots where moisture lingers.
Sunday stays mild but cloudier, with highs in the mid-50s and another cool night to follow. Early next week trends slightly unsettled, with increasing cloud cover and a growing chance for rain by Tuesday night into Wednesday, signaling a possible shift toward wetter conditions.
For now, plan extra time during morning drives, use low-beam headlights in fog, and avoid sudden braking. Conditions can change quickly before noon.
