#snow is a hashtag that allows you to view lists any other occurrences of this word. It's actually fairly useful - not in this case - when there are news events happening. For instance during the Paris attacks, people were posting #PorteOuverte to allow people safe houses when attacks were going on.

Or #uksnow is commonly used when people report snow that is use by websites such as uksnowmap.com. I think it's fairly clever and interesting.
