It looks like Southern California will kick off December with a cold, wet, and rainy start!

While the week started off with some clouds and sun, cool onshore breezes, and below-average temperatures, things really kick into full gear beginning Thursday and lasting through the weekend. 

That's when the region is expected to experience periods of wet weather, colder temperatures, and even some mountain snow.
