Winter returns as Southern California braces for back-to-back weeks of rain, snow

LOS ANGELES – Southern California is bracing for a shift from unseasonably warm conditions to a series of winter storms, beginning with a light system Tuesday and transitioning into a much more aggressive, cold pattern by next week. 

What we know:

Enjoy the sunshine on Monday as it remains the final warm day of the stretch, with temperature 10 degrees above normal for many areas, according to the National Weather Service. 

But by Tuesday evening, rain is expected to spread across the region, particularly the Central Coast and coastal slopes, the NWS said. 

Estimated rainfall totals for this first storm system are between 0.25 and 0.50 inches for most areas, though coastal slopes could see up to an inch due to winds. 

The storm is predicted to be relatively light in comparison to a “major pattern change” starting Saturday night that is forecast to bring multiple heavy, cold storm rounds through late next week.

What we don’t know:

While confidence is high on what to expect with this first round of winter weather, there is uncertainty regarding a much stronger system looming for the following week, according to forecasters. 

Some models are suggesting much higher rainfall totals – between 2 and 3 inches – for the mid-week period, as the timing continues to be monitored by meteorologists. 

The exact timing and intensity of the cold front expected next Sunday also remains uncertain due to the prolonged seven-day outlook.

Timeline:

Monday: Mostly cloudy by afternoon; remaining warm with highs in the 70s.Tuesday: Rain chances begin in the morning for the Central Coast, spreading south toward Ventura County by evening.Wednesday: Peak rain arrives early morning; showers linger through the afternoon as temperatures cool further.Thursday–Friday: A brief drying trend with the “nicest day” expected Friday under a temporary ridge.Saturday Night — Sunday: A major pattern change begins with rain overspreading the area and snow levels dropping to 5,000 feet.

What’s next:

People are advised to prepare for a much more active weather window between Feb. 14 and Feb. 19, the NWS warns. 

This period is expected to feature multiple rounds of rain and significantly cooler weather conditions. 

Forecasters are calling it a “major pattern change” that will be updated as the system draws closer.
