Here's an article previously posted by Geos on SSW's and how they can bail out a snowless winter in the PNW lowlands, even in an El Nino.  Some of the classic PNW winters were started by an SSW.



That graphic showing the evolution of the SSW last winter is pretty amazing.

No SSW on the horizon.

Not yet!

I’m starting to become interested in the period around the Holidays. But still many ways that could fail.
