I mean, yeah it's unusual, I guess, but it's not like it's unprecedented.

*Yes. I remember those wintersthat happened from time to time as I was growing up, fun at first, the becomes as drag as you take on adult responsibilities.

The snow hits at the point of transition from cold front to warm front; the precipitation moves in off the water but the temperatures are still low enough for it to fall as snow. This is why we have gotten walloped with snow when the temperatures are between roughly -3C and 3C, but it's been sunny and crisp when temperatures fall below that range and rainy, "normal" west-coast weather conditions when temps have been warmer.
That said, this is considered to have been a very weak La Niña so that says winter as we've experienced it this year could have been much worse.

Yes, I've read up a bit pn the enormous, period, often anomylous Pacific Ocean current cycles, and what a La Niña winter means. The Pacific is so huge it produces unique phenomena.
Example: the warm jetstream Pineapple Express doesn't come from Hawaii, but from waters around Fiji in the Southern Hemisphere!
Another, the upwelling cold corrent off the northern half of Baja California. On the Pacific side Of the peninsula, desert high sun, but cool with afternoon mist. Seaside; low 15° High 21°.
The ocean there is cold, a dark sludgy green in color,and no good for surfing. A lot of fish and seaweed. (it's also very rocky).
The eastern side, in The Sea of Cortez, are the the world's most northerly coral reefs, and 40++° temps. in high school often read was "The Pearl," by Steinbeck, set here, (tho' ++south)

any meteorologists out there?
