Is this a lot of Snow? Interpret These Snowfall Graphs

Okay, you say this is a lot of snow, right?  

Take a look at these snowfall graphs from Royalston, in North Central Massachusetts.  Would your students be interested in discussing/interpreting these? 

Is this more snow than "normal"?

Would graphs of snowfall in your town be similar as these or different?
