So the thing is, he is not making any specific predictions per se. Notice the wordings: "may not mean", "you may feel", "favorability/potential". If our hoped for pattern does indeed fail, he will surely crow "I told you so". If there is an epic snowy period, he'll just say: "I said 'may', not 'will'".
I'd have more respect if he said something specific like: I predict that the advertised pattern will occur but very little snowfall will result..."
