California – Headlights glow faintly through a curtain of dense fog across Sacramento this morning, softening the city’s edges and slowing early travel along I-5 and Highway 99. Pavement feels damp under steady mist, and the crisp December air hints at another round of wet weather building for the middle of the week.
The National Weather Service continues a Dense Fog Advisory across portions of the Central Valley as visibility drops to a quarter mile or less. These pockets of thick, stubborn fog may persist into the early afternoon. Drivers should move slowly, use low beams, and leave extra braking distance — small shifts in terrain or traffic can hide sudden low-visibility zones.
Clouds hold firm today with highs near 50. Conditions stay cool, and patchy fog redevelops this evening as calm winds return. Meteorologists are now tracking a Tuesday moisture push, with a 30% chance of showers by late afternoon, followed by stronger rain potential Tuesday night. This early-season setup brings slick roads rather than winter precipitation, but temperature whiplash could still trigger patchy frost in outlying areas if skies briefly clear before rain arrives.
By Wednesday, shower coverage increases to around 60%, then tapers late in the evening. Another system lingers nearby, hinting at additional December rain chances into the weekend — a developing pattern that could complicate Christmas travel for those hitting the road early.
