Hi! I am going to Xian on 10-15 january 2015. May I know is it snowing there?

Well, according to the weather forecast, the temperature during that period of time is 23 F to 48.2 F. It's cold and has large temperature difference. But it mainly contains sunny days. So it maybe doesn't snow in the following days. You should remember to bring your thick overcoats, jackets and pants in order to keep warm. :-)
