More L.A. rain is on the way: A timeline of what to expect

"The cold front will have moved away from Los Angeles, but the cold core of the low-pressure system will still be around. Snow levels were at around 7,000 feet on Monday but were expected to drop to 5,000 feet by Tuesday. Officials issued a winter weather advisory for the eastern San Gabriel Mountains and the northern Ventura County mountains that is set to last through Tuesday night. About 2 to 5 inches of snow could fall in the mountains."

""As for the Grapevine area, there is a chance of a dusting of snow Tuesday morning as the snow levels lower," the weather service said. The Grapevine is a key travel corridor on the 5 freeway that connects L.A. and Santa Clarita with the Central Valley and the San Francisco Bay Area. The highest point of the Grapevine section is the Tejon Pass, which peaks in elevation at 4,144 feet above sea level. At that location, "some non-accumulating snow is possible," the weather service said."

A cold core from the recent low-pressure system will keep instability in place Tuesday, allowing a small chance of scattered showers and isolated thunderstorms. Snow levels are expected to fall from about 7,000 feet to near 5,000 feet, prompting a winter weather advisory for the eastern San Gabriel and northern Ventura County mountains with 2 to 5 inches possible. The Grapevine and Tejon Pass could see a dusting or non-accumulating snow, potentially impacting travel. Coastal and valley temperatures remain cool. Wednesday will be sunny and cool, then a larger storm Thursday could add 0.25 to 0.75 inches of rain.
