Drizzle is expected Wednesday with temps in the mid 60s in Los Angeles and Orange County. There is a 20 percent chance of showers Thursday and a 40 percent chance of rain Saturday.
The valleys and Inland Empire will also see temps in the 60s, Wednesday through Saturday with a chance of drizzle and even rain.

"It's kind of weird," said Chatsworth resident Cindy Mora. "I would expect it to be really cold. But I guess this was nice weather for today."
Some transplants to Los Angeles find it hard to believe.
"I'm actually from Pittsburgh and Buffalo, so 80-degree weather here is a little unusual," said Lee Gordon of Granada Hills. "With the Christmas spirit with other people, you start to feel it."
