A swift-moving winter storm will blow into Kern County on Tuesday, dropping about a quarter-inch of rain on the San Joaquin Valley and up to a foot of snow above 4,000 feet in the Sierra Nevada.

It will be mostly gone by Wednesday, said Mike Bingham, a meteorologist with the National Weather Service in Hanford, with only spotty showers and snow flurries lingering in the mountains.

The system is expected to move down the valley late tonight, and rain is expected to begin on Tuesday.

Bingham said the bulk of the system will move through the area on Tuesday.

About a foot of snow is expected in the Sierra Nevada, he said, with around three or four inches expected in the mountain passes around Tehachapi and the Grapevine. Snow levels could drop as low as 3,000 feet.

Reports on the Hanford Weather Service facebook page indicate the winter weather could make the roads dangerous or impassable.

Most of the valley can expect a quarter-inch of rain with some areas getting up to half-inch.

Bingham said the system should be similar to the last storm that blew through the area.

That system dusted the mountains with a blanket of silver and white on Feb. 8, and closed the Grapevine for some time.
