SACRAMENTO (CBS13) – It’s been a warm start to fall, but that’s about to change, with temperatures next week dropping about 25-30 degrees from this week’s highs.
By Sunday, a cold low pressure system is expected to drop into the valley from the Gulf of Alaska, according to the National Weather Service. As the main low pressure system becomes established off the coast on Sunday, cloudiness and cooler air will bring daytime highs down to the 70s and high 60s. Overnight lows could drop into the high 40s.
A cold front is expected to swing through Northern California on Sunday night into Monday, bringing with it wet weather to much of the region.
A quarter of an inch of rain is projected for the Central Valley on Monday into Tuesday. Snow levels will start at about 6,000 feet over the northern Sierra Nevada, with several inches of snow expected over the mountain passes.
The National Weather has issued a winter storm watch for areas above 5,500 feet from Sunday night through late Monday night. Six to 12 inches of snow is possible, with wind gusts up to 40 mph.
The chance of showers in the Sacramento area extends into next Thursday.
