I would call them. The worst case scenario is they will fully refund your tickets, if they cancel it, and you are traveling to this area from afar. If you are local, they might offer an exchange date. Contact your point of sale to find out options.
I agree, call them to inquire about their refend/exchange policy. Pending what the weather we actually get, the show may go on.
I was just there two weeks ago during a "bad noreaster" and it was business as usual. The storm wasn't bad at all. Double check though.
