A strong low pressure system sliding south from the Pacific Northwest into the Sacramento region will prompt windy conditions and a chance of isolated showers and thunderstorms in the area Saturday.

The National Weather Service also issued a wind advisory, noting that high winds “may topple drought-stressed trees and damage power lines” in some areas of Northern California.

Cooler temperatures will accompany the building low-pressure system, with Saturday’s projected high of 80 being 12 degrees cooler than Friday’s high of 92 at Sacramento’s Executive Airport.

Nathan Owen, a meteorologist with the National Weather Service in Sacramento, said rain is more likely to fall this afternoon and evening in the Sierra Nevada.

“It’s going to be hit of miss in the valley,” he said.

Owen said winds are expected to build Saturday afternoon, with gusts of around 15 to 20 miles per hour in the Sacramento area and up to 40 mph in the Sierra Nevada.

Daytime high temperatures will return to the mid-80s by Wednesday.
