Southern California’s weather is about to take a major turn.

After a stretch of ideal spring days with highs in the upper 70s and 80s, a low-pressure system will sweep through the region this weekend, bringing cooler temperatures and rain.

“A ridge of high pressure over SoCal is breaking down and sliding to the east,” said KTLA 5 News weather anchor Kaj Goldberg. “As that happens, it will allow the clouds to begin to fill in as the cold front moves in.”

Daytime high temperatures will drop by about 10 degrees on Friday in most locations. When the rain arrives Saturday, much of Southern California will see highs in the low to mid-60s, Goldberg says.

Rain showers will be scattered and limited to less than an inch in the coastal areas and valleys of metro Los Angeles, according to the National Weather Service. Mountains and foothills could see up to 2 inches of rain by the time the storm system moves out on Sunday.

“This is not going to be a big rainmaker, but it will certainly bring us cooler weather with cloud cover and rain showers off and on,” said Goldberg.

Snow levels are expected to drop to around 4,500 feet. One to four inches of snow is forecast at lower elevations, and 4-8 inches are possible on higher peaks, the Weather Service said.

Southern California can expect clear skies and daytime highs in the upper 60s and low 70s on Monday and Tuesday of next week.
