Rain moves into Southern California on Saturday. Here's what to expect

LOS ANGELES (KABC) -- It's still April, but May gray is definitely here, bringing weekend rain to the forecast.

The National Weather Service has issued a winter weather advisory all across the mountains of Southern California, forecasting 3 to 5 inches of snow by Saturday night.

An area of low pressure and a trailing cold front is approaching the California coast. Southerly winds right ahead of the front are generating showers, meaning a band of rain is headed our way.

The front is expected to arrive in Southern California in the late morning on Saturday -- around lunchtime -- producing the snow in the mountains and rain elsewhere. The front isn't expected to arrive in the Inland Empire until the afternoon.

Rainfall totals will generally be less than a half an inch for most areas.

After the front moves through, residual moisture will still hang around, though the skies should clear up by Sunday afternoon.

Los Angeles and Orange counties Saturday will stay on the cool side, with a high of 62. Expect a lingering 20% chance for showers Sunday and then a beautiful, warm week after that.

The valleys and the Inland Empire Saturday can expect a 70% chance of rain with a high of 60.

At the beaches Saturday, expect rain with a high of 61 degrees and a low of 53.

Mountains can expect snow, with a high of only 42 and a low of 20. Though, like the rest of the region, temperatures are expected to warm back up next week.

Deserts Saturday can expect gusty winds, with a high of 54 degrees and a low of 39.
