Southern California Braces for Wet Christmas as Atmospheric River Arrives

Holiday shoppers in Southern California are bracing for a wet Christmas as a developing weather system threatens to bring rain to the region.

Weather System Overview

Meteorologist Melissa Magee said the jet stream above the Southland is expected to buckle, allowing moisture to move south. She described the incoming system as an atmospheric river from the Pacific Northwest that will likely bring rain rather than snow.

Timing and Potential Impact

Magee highlighted that the system could arrive around Christmas Eve and Christmas Day, with showers expected Tuesday into Wednesday (Christmas Eve) and continuing into Thursday. She noted the exact timing and intensity are still being fine‑tuned.

Forecast Uncertainty

While the long‑range forecast points to a storm during the holiday, it is too early for precise predictions. The meteorologist emphasized that the system is milder and primarily rain, with little snow expected.

Key Takeaways

• Jet stream expected to buckle, allowing moisture into Southern California.
• An atmospheric river from the Pacific Northwest could bring rain on Christmas Eve and Christmas Day.
• Forecast timing and intensity remain uncertain; no significant snowfall anticipated.

With holiday plans underway, residents and visitors should stay alert for changing weather conditions as the system moves in, and prepare for possible rain during the festivities.
