I lived in the East Los Angeles metropolitan area from 1946-1998, and in Red Bluff, California, from 1998-2017. We rarely saw snow fall and it melted quickly in these areas. We always had to drive up into the mountains, e.g., the San Gabriel or San Gorgonio Mountains in the LA area, or Mt. Lassen or Mt. Shasta in Red Bluff if we wanted to play in and enjoy the snow.
Here in Vancouver, Washington, where we live now, snowing is a more common occurrence. I think that last year Vancouver had about 8 - 10 inches of snow. The nearby foothills and mountains (Mt. St. Helens, Mt. Adams, Mt. Ranier, and Mt. Hood of the Cascades) have lots of snow.
Last night, about three inches fell as temperatures dropped and the cold front rolled into the Northeast Pacific Coast region.
We live about 500 miles north of Red Bluff, and 300 miles south from Vancouver, Canada.
