@hasmis Oh I’m not saying it isn’t being blown out of proportion by the clickbait crowd, but SSWs have been a useful tool for us in the Pacific Northwest to predict lowland snow events 2-3 weeks out.

The earliest mention I remember of it associated with a forecast was 2019. SSWs are caused by, and then further disrupt, the wave pattern on the southern edge of the polar vortex (another term that is clickbaited into oblivion).
