SoCal storms timeline
Here's a look at what to expect from this week's storms.
A system over the Pacific dropped south Tuesday into Wednesday as it neared the California coast and moved into the Los Angeles area.
Widespread light rain is in the forecast Wednesday morning with the best chance for wet weather from 10 p.m. Tuesday to 10 a.m. Wednesday. Snow levels will be around 4,500 to 5,500 feet. There is a 20-percent chance of thunderstorms.
"By 10 a.m., we're mostly done with the rain. A few isolated showers this afternoon," said NBCLA forecaster Belen De Leon.
Wednesday night into Thursday, scattered light showers are expected with the most activity in SoCal's mountains. One to 2 inches of snow are possible on the Grapevine section of the 5 Freeway north of Los Angeles.
"The Grapevine, watching that very closely, because it does seem a couple of inches are possible Wednesday night if there's enough moisture left over once that cold air settles on top of it," Magee said.
Looking ahead to the weekend, light rain is possible with snow levels dropping to 3,000 feet.
