Winter is drawing closer, bringing cooler temperatures and the potential for snowfall in mountainous areas of Southern California as a Pacific storm system approaches the region.
While much of Southern California has experienced relatively warm conditions in recent days, forecasters say temperatures are expected to gradually decline beginning this weekend.
Through Thursday, December 18, highs are projected to reach around 81°F (27°C) in some areas. By the weekend, however, daytime temperatures could drop to approximately 70°F (21°C).
According to long-range forecasts from the National Weather Service, a storm moving in from the Pacific could bring snow to mountain communities, potentially complicating travel in the days leading up to Christmas. Snowfall is most likely beginning around December 22.
Meteorologists are also monitoring the possibility of heavy rainfall in parts of the state between December 23 and 26.
Forecasters note that snowfall may not be particularly intense in some areas. An upper-level trough is expected to initially draw moisture from the southwest, followed by additional moisture moving north from the south, limiting snow accumulation in certain regions.
Residents and travelers are advised to stay informed as conditions develop, especially when planning trips through mountain passes during the holiday period.
