Rain, wind, snow and frigid temperatures are on their way to the Southland this weekend, with expectations of heavy showers, snow in the mountains and possible thunderstorms, according to the National Weather Service.
The downpour is expected to begin late Friday afternoon, with about an inch of rain expected in the coastal and valley areas and one to three inches of snow in the mountains, said weather specialist Stuart Seto of the National Weather Service.
"The rain will get heavy at times, especially overnight Friday," Seto said. "This is ahead of the front. Once the front comes in we will get cold air and rain which means thunderstorms."
The Grapevine will see snow behind the front, and Seto said he expects gusty winds between 20 and 30 mph overnight in the mountains, with gusts up to 50 mph, possibly "making visibility zero at times."
Snow levels overnight Friday will drop to 1,000 to 1,500 feet, with the heaviest snow in the East San Gabriel Mountains at 12 to 22 inches above 4,000 feet.
"Take this storm very seriously," Seto said. "We will have some very cold temperatures. With wind and moisture in the air it can really get chilly."
Cold winter conditions are expected through Wednesday while the storm is expected to last through Saturday night, according to the National Weather Service.
