Temperatures Plummet Nearly 30 Degrees As Storm Moves Into LA

LOS ANGELES, CA — Within the course of 48 hours, Southern California swung from a heat advisory to a winter weather advisory as temperatures dropped nearly 30 degrees.

Southern California's heatwave came to a dramatic end Monday as record high temperatures dropped across wide swaths of Los Angeles County. From unseasonably high scorching temperatures that baked the region over the last week, Tuesday will bring notably cooler temperatures, a chance of rain and snow to the local mountains.

According to the National Weather Service, Tuesday's high for Downtown Los Angeles is 60 degrees with a 30 percent chance of rain. That's down 29 degrees from Saturday's record high of 89 degrees.

The local mountains may also get a light dusting of snow. Above 3500 feet, local mountains are expected to get a couple of inches of snow Tuesday, according to the National Weather Service.

Drivers are advised to expect slippery road conditions, gusty winds and snow on the Grapevine.

"Well this will be a change. A winter storm will drop into southwest CA on Tuesday bringing a few showers and much cooler conditions," the Weather Service in Los Angeles tweeted. "It will be windy, especially in the mountains where snow accumulations will occur mainly above 3500 ft."
