California wakes up under a thick gray veil as dense fog settles across the Sacramento Valley, swallowing headlights and blurring familiar skylines. Moist air hangs low over roads and rivers, making even short drives feel uncertain as the morning unfolds.
A Dense Fog Advisory remains in effect across Sacramento and surrounding communities through late morning. Visibility has dropped to a quarter mile or less in many areas, especially near the Delta, river corridors, and open farmland. Drivers may encounter sudden near-zero visibility with little warning.
Travel impacts are most pronounced along I-5, Highway 99, and surface streets near the American and Sacramento Rivers. Slow speeds, increased following distance, and constant headlights are essential right now. Conditions may vary block by block, which increases risk during early travel hours.
Temperatures sit in the low 40s, keeping moisture locked close to the ground. Calm winds allow fog to persist longer than usual. While widespread icing is not expected, damp pavement may remain slick in shaded areas through midmorning.
Improvement arrives later today as fog gradually lifts and clouds thin. Skies trend partly sunny by afternoon, with highs climbing into the low 60s. The air feels noticeably milder for early February once visibility improves.
Tonight turns calmer with patchy fog redeveloping after sunset. Cooler temperatures return to the low 40s, setting up another fog-prone morning on Monday. Drivers should remain alert during early hours.
Looking ahead, a quiet and mild pattern settles in. Tuesday through Thursday bring mostly sunny skies and highs in the mid-60s. Winter stays subtle for now, though overnight fog remains a recurring concern during clear, calm nights.
Meteorologists continue monitoring valley moisture levels closely. Conditions can deteriorate quickly when fog reforms, especially near waterways.
