雪

xuě - snow

雪 is a word that I've know for a long time, but I couldn't not use it today. Also, 大雪 (not to be confused with 大学) normally refers to one of the 24 solar terms, which is mentioned in A Key to Chinese Speech and Writing, but here (according to dict.cn at least), it just means a heavy snowfall. And don't forget 白雪 is Snowy in Tin Tin and shouldn't be confused with 白雪公主, who is Snow White.
