Cold storm system on its way, complete with possible thunderstorms and snow

Los Angeles Times Staff Writer

Say goodbye to the summer-like weather. A wintry storm is expected to sweep through Southern California beginning Thursday and could bring thunderstorms.

The "primary impact of this system will be temperatures," with the mercury falling into the 30s and 40s along the coast and in the valleys; temperatures could dip below freezing in the Antelope Valley, the National Weather Service said.

The Grapevine on Interstate 5 could see snow showers and gusty winds Thursday night into Friday morning, the weather service said.

Forecasters called the storm "exceptionally cold for this time of year, but with not a lot of moisture and as a result not much in the way of precipitation." The valleys could see 0.10 to 0.25 inches of rain, while the mountains could see 0.25 to 0.5 inches of rain.

The cold low pressure system is moving south from Alaska along the West Coast. Showers could last through Saturday.

Temperatures are expected to get back to normal by Sunday.
