At first glance at the photo below, you might think you're looking at snow dusted mountains in Colorado.
It's actually from the Santa Monica Mountains in Southern California, which saw light snow on Thursday as well as in many other cities nearby.

A very cold upper level low pressure system moved through the area, helping drop snow levels down to as low as 700 feet and allowing for snow to fall in places such as Malibu, Thousand Oaks, Pasadena, Simi Valley, and other surrounding communities near Los Angeles.

There was no official report of snow in downtown Los Angeles, and it's been a while since an event like this one.
According to the National Weather Service in Los Angeles, it was back in 1962 that there was a trace that fell on January 21 and 22.
Measurable snow in the City of Angels has only been on record twice since 1877 -- on January 9, 1949, and also on January 15, 1932.

The last significant and widespread measurable snow to affect the Los Angeles and Ventura County valleys was on February 8th, 1989, when up to 5 inches of snow fell in portions of the San Fernando Valley westward to Thousand Oaks and Simi Valley.
