California – Cool air lingers over Los Angeles this morning, with damp pavement and low clouds hinting at changes ahead as year-end travel accelerates. Drivers heading out early notice crisp air, light breezes, and a calm start that won’t last all week.
According to the National Weather Service, much of Southern California begins Monday dry and mild, with highs near 70 degrees in Los Angeles. Clouds increase tonight, setting the stage for a wetter pattern by midweek as a large national storm reshapes weather across the country.
While Arctic air and blizzard conditions hammer the Plains and Great Lakes, California sits on the quiet edge of the system. Still, impacts arrive here in subtler ways. By Tuesday night, rain chances rise across Los Angeles and surrounding communities. Wet roads and reduced visibility become more likely during evening commutes, especially along I-5, I-10, and Highway 101.
Rain turns more widespread Wednesday, with temperatures cooling into the 60s. Patchy fog may develop during heavier showers, creating slick conditions after sunset. Travelers heading into New Year’s Eve celebrations should plan extra time and expect slower traffic. By New Year’s Day Thursday, periods of rain continue, keeping roads damp for holiday gatherings and return trips.
The bigger story remains contrast. While much of the nation deals with snow, ice, and flash-freezing roads, Southern California’s risk centers on wet pavement, fog, and sudden slowdowns during peak travel. Even brief downpours can trigger spin-outs and congestion.
Conditions stay unsettled into the first days of 2026, and additional advisories may follow if rain intensity increases. Traveling this week? Share what you’re seeing on the roads as the New Year approaches.
