California – Streetlights glow through a low gray haze across Los Angeles this morning as patchy fog settles into valleys and neighborhoods. Visibility drops quickly in spots, and the calm start can catch drivers off guard during early travel.

According to the National Weather Service in Los Angeles/Oxnard, patchy dense fog is expected through the morning hours, especially in inland valleys and lower elevations. Visibility may dip below one mile at times before gradual clearing late in the morning. Temperatures stay mild, climbing into the upper 60s and low 70s by afternoon.

Drivers along I-5, I-10, U.S. 101, and surface streets should slow down and use low-beam headlights where fog thickens. Moist pavement from overnight humidity can also turn slick, particularly on ramps and shaded roadways. Morning commuters should allow extra time and watch for sudden stops.

Saturday follows a similar pattern. Fog redevelops early, then breaks for sunshine by midday with highs near the upper 60s. Sunday stays mostly cloudy and mild, but clouds thicken again, signaling a shift early next week.

Meteorologists are tracking a developing change as Christmas travel approaches. Rain chances increase by Tuesday and Wednesday, with steady showers possible into Christmas Day. While snow is unlikely at lower elevations, higher terrain could see early winter impacts if colder air filters in behind the system.

For now, the main concern is visibility. Keep windshields clear, reduce speed in fog, and stay alert during early drives. The weather remains quiet this weekend, but conditions will turn more active heading into next week.

More updates are expected as the rain timeline sharpens. Driving this morning or planning holiday travel? Tell us what conditions look like in your area.
