December 30, 2025 7:28 am
Southern California Overview:
- Cloudier conditions with warm weather is expected today. Santa Ana winds remain gusty this morning, then weaken by this evening across the mountains and western valleys. A low pressure system will bring periods of showers for New Year`s Eve and New Year`s Day with the potential for more cloudier and wet weather by the end of the week into early next week.
- Heavy lake-effect snow expected to linger across the Great Lakes as a big cyclone pivots away into eastern Canada. Arctic air will dominate the eastern two-thirds of the country including Florida followed by a quick warm-up across the Northern and Central Plains amid a mild and tranquil Intermountain West. Rain associated with an anomalous low pressure system from the tropical latitudes is forecast to bring the threat of flash flooding for southern California on New Year's Eve into New Year's Day.
