I disagree. That chart may matter a lot or a little or not at all. And the latest link from eagles does not make that crystal clear. If temps jump non-linearly off that trend line with El Nino in my neck of the woods - which the chart at least implies is possible, then there is little doubt that my neck of the woods will be impacted in terms of snow quantity and quality.
Some of you guys live in places where snow usually falls cold. A degree or two difference is neither here nor there. In the Cascades, lots of our snowfall is right on the margin. Yes, we get a ton of snow. But we also get rain events. And much of our "base building" snow is just this side of being snow.
Looking at Tony's charts, my local areas are strongly favored by La Nina and negatively impacted by El Nino. Now (as Tony noted) when an average year is 400 to 500 inches or more, getting only 75% of that may not sound so bad. But if we really are seeing more of a temperature step function as the chart implies - that could be quite interesting in a not so happy way.
To my mind, cutting out the discussion of that chart (until someone lays out a clear case rebutting its rather rough implications - which I am more than open to), is simply letting politics get in the way of the winter snowpack discussion. Just my .02.
