A soggy and cool start to December continues this week when another storm moves into Southern California.

A cold storm will move across the region Tuesday and bring snow and scattered light rain. Snow levels will drop to 5,000 feet in SoCal's mountains.

Thunderstorms are possible Tuesday afternoon.

"The main rain doesn't get here until (Tuesday) afternoon," said NBC4 forecaster Belen De Leon. "Some of these showers could linger into the evening hours."

Light showers might continue into Wednesday morning.

Only about .25 inches of rain is expected from the early December storm. About an inch of snow is expected in the mountains.

Highs will be in the 50s and 60s for most of Southern California, below normal for this time of year.
