The shortening of the wave legths itself is inherently sufficient to "completely disrupt things". I thought you knew that.
Does it have to mean snow and cold?
No.
I def. don't see a 2018 like turn around...I was confident of the big finish heading into that seaaon and it was apparent by this time that year that the script would indeed flip. However, I still think this one has more to offer than this.
I think everyone understands that the pattern sucks for sne...I think its best for the welfare of the forum if we just operate under the assumption that that is implicit, and refrain from pounding anyone over the head that dares to discuss snow during winter in a weather forum.
