I can firmly predict that many of the predictions, whether informed, uninformed, sophisticated, scientific, heuristic, statistical, intuitive, mystical, or just flat-out clueless, for the arctic weather in mid-May, ten days from now, will be wrong. Some of them will also come close to the truth.
The thing that I find fascinating about this subject is that there's no readily apparent correlation between the amount of money, science, expertise, and technological awesomeness that goes into such predictions and their eventual accuracy.
