Make sure to bundle up this weekend, as frost warnings are in place for parts of Kern County.

From Saturday night to Sunday morning, a freeze watch is in place in Kern County's deserts. And in the valley, frost is expected Sunday morning before 10 a.m., according to the National Weather Service.

In the deserts, temperatures are expected to drop to between 22 and 28 degrees. Periods below freezing, or 32 degrees, will last for up to seven hours.

"It's enough to kill plants, things like that," said Jim Andersen, meteorologist with the National Weather Service. "Keep an eye on your pets."

The most recent frosts come after a Friday afternoon and night of cold weather. In Bakersfield, overnight temperatures had been expected to drop to 40 degrees.

Some places saw snow. In the Tehachapi Mountains, snow dropped down to 3,500 feet. Wind gust up to 45 mph through and below the mountain passes. And in Frazier Park, snow levels dropped to 4,200 feet, and temperature only rose to 28 degrees.

A storm has left up to 18 inches of snow in the Sierra Nevada and raised the hopes of skiers and snowboarders after a subpar snowpack last winter.

Frigid temperatures also have allowed ski resorts to crank up snow-making machines in advance of the Thanksgiving holiday period.

Mammoth Mountain Resort, just east of Yosemite National Park, says the storm brought 6 to 12 inches of new snow. It was the only resort open in California on Friday, a day after it began operations for the season.

Boreal Mountain Resort, atop Donner Summit north of Lake Tahoe, plans to resume daily operations Saturday after receiving 8 inches of new snow.

Northstar California resort, just north of Lake Tahoe, reports up to 18 inches of new snow.

Grapevine drivers also needed to exercise caution Friday night as it rained and, in the higher elevations, snow fell.

"It's very light showers and snow showers, but any frozen precipitation can create problems," Andersen said.

Once Saturday night and Sunday morning's cold passes, the weather should warm up until Tuesday. Tuesday's high in Bakersfield is forecast at 69 degrees. After that, the temperature will dip again, but only by a few degrees.

"We're looking at most of the weather moving through now," Andersen said Friday night.
