It looks unusual, and I agree with you that it might be an example of the things to come. But I'd love to see an analysis of snowstorms in central Spain using extreme value theory. It might not be that infrequent. In EVT terms, the return level might not be more than a few decades. Central Spain is quite cold. For example, when the International Brigades came to fight in the Civil War they were expecting a mild Winter, but they were shocked by pretty extreme temperatures. Luckily, everyone got prepared as next few years were even worse. In 1937, Teruel Battle was consistently fought below -20 C. Aside from 1937, 1956 and 1971 saw pretty intense snowstorms. The 1971 one was much worse than the current storm according to the data I've seen.
