I understand that too and I have suggest that the warmer climate, while it doesn't nullify analogs and teleconnections, might render them less effective prediction tools. I will stop short of saying things don't work like they used to, because of what I said above, but I think there is at least some possibility that things are being impacted in a way that we don't fully grasp, which, if true, would make it less cold today under similar patterns of the past, thus making it harder to snow, particularly later in the season. I think it is at least a possibility worth acknowledging.
That said, making a statement like it can't snow when daytime highs are in the 40s, using a two week out ensemble mean as your baseline, is a little foolish.
