Rain, Snow Returning To Northern California This Weekend

SACRAMENTO (CBS13) - The forecast for the weekend has changed - it'll be warmer but also wetter.

A Pacific frontal system will move inland over Northern California on Saturday, bringing light rain to the valley and more snow in the Sierra.

This system should only produce about a half-inch of rain, but snow levels will be fairly low because of the cold air, around 3,000 feet elevation. Up to 4 inches of new snow could accumulate.

Overnight temperatures this week have dropped below freezing and it will be foggy and frosty Friday night, but the cloud cover will keep it warmer this weekend. Overnight lows should stay in the 40s. Highs will be in the mid-50s.

The wet weather is expected to fizzle out by Sunday afternoon, giving way to clear skies overnight and into Monday.

The Sierra snowpack is already well ahead of last year's pace after a series of big storms. The first survey of the season earlier this week read 133 percent of normal.
